Zoonotic infections (swine-human) caused by influenza A viruses (IAVs) have been reported and linked to close contact between these species
we describe eight human IAV variant infections (6 mild and 2 severe cases
Genomes recovered were closely related to Brazilian swIAVs of three major lineages (1 A.3.3.2/pdm09
Five H1v were closely related to pdm09 lineage
one H1v (H1N2v) grouped within 1B.2.3 clade
and the two H3v grouped within a clade composed exclusively of Brazilian H3 swIAV (clade H3.1990.5.1)
Internal gene segments were closely related to H1N1pdm09 isolated from pigs
IAV variant rarely result in sustained transmission between people
however the potential to develop such ability is of concern and must not be underestimated
This study brings into focus the need for continuous influenza surveillance and timely risk assessment
we describe in detail eight cases of zoonotic infections of swIAV in humans that occurred in Brazil from 2020 to 2023

Case 1 patient sought medical assistance and was fully recovered after treatment. Notably, one co-worker presented similar symptoms at the same week, and 218 employees of the slaughterhouse presented ILI symptoms within a window of one month before and two months after Case 1 diagnostic (Supplementary material)

Swine sequences isolated in Brazil contains the state of isolation within its names (Brazil_MG = Minas Gerais
The accordant clustering and by assuming that these are not related human infections indicate that this lineage is circulating among pigs without any reassortment
The recognition that this lineage is being maintained in the swine population and managed to be transmitted from swine to humans
is alarming and suggests that this combination of genes may facilitate the jump of the virus between the two species
and all branch lengths are drawn to scale representing nucleotide substitutions per site

B Topology details of the H3 Brazilian clade and subclades (1990.5.1
No available vaccine strain or CVV is in the genetic group correspondent to the clades of variants found in Paraná
due to the inability to isolate the IAV variants for functional testing
we could not investigate potential new genetic markers
and the real effect of the reported genetic markers found in IAV variant detected in Brazil
This criterion excludes many rural areas where variant influenza likely circulates initially
Strategically placing units in rural regions of swine and poultry production or advising the population and workers in these areas to seek care at existing sentinel units
can help enhance the capacity to detect influenza variants
Influenza A viruses can be regularly transmitted from humans to swine15
and might then be reintroduced to humans as novel reassortant viruses
The eight influenza variant viruses described here were first detected by LACEN and sent for sequencing at the NIC
that is responsible for characterizing strains for which regional laboratories detect either influenza A or B viruses but are not able to identify the viruses to the subtype or lineage level
the gene segments of all variant viruses grouped within swine clades
some gene segments were closely related to human viruses (for instance
the intensive surveillance of human influenza along with the long branch observed in the phylogenetic tree suggest the absence of swine sequences rather than unsampled human viruses
has ‘genetic potential’ to be transmitted from pigs back to humans
The same clustering pattern across different phylogenetic trees for some of the cases (especially Cases 6
7 and 8) also brings into the discussion the possibility of a sustained transmission of this lineage within the human population instead of separate swine-to-human transmissions
the genomic pattern observed in the H3N2v in Case 4 and Case 5
suggest the occurrence of limited transmission among individuals sharing the same residence
These findings highlight the remarkable ability of swIAVs in crossing inter-species barriers and to quickly be transmitted between close contacts
The phylogenetic clades defined for the influenza A virus variants described in this study also revealed differences in the genome constellations
This demonstrates the high diversity of strains that can cross the animal-human barrier
reinforcing the need to improve surveillance both throughout the country and in the region
A constellation of genes in a particular influenza strain within a specific host determine the pathogenicity or virulence of an influenza virus
Few described genetic markers associated with pathogenicity
or virulence were observed in the analyzed genomes
and no phenotypic studies have been conducted on them
we cannot exclude the possibility that these viruses possess as-yet unidentified markers that may confer an advantage in adapting to the human species
We emphasize the need to preserve the collected samples to ensure viral integrity and allow the virus isolation for functional and phenotypic testing
The genetic data observed may indicate antigenic mismatch and a potential lack of immune protection against the IAV variants
The worker’s swine industry should be included in the preferential group for influenza vaccination of the Brazilian MoH
once the transmission of human seasonal influenza viruses to swine has heavily influenced the extensive genetic diversity observed in swIAVs (15)
These new Brazilian IAV variant cases were considered as sporadic cases and had good clinical outcomes that did not spread throughout the local human population
and actionable surveillance systems remains the key to early detection of the threat posed by new influenza variants
This study was conducted under the terms established by the Ethical Certificate presented for appreciation (CAAE) to the Brazilian Platform (http://plataformabrasil.saude.gov.br/) and approved by the number 68118417.6.0000.5248
The SISGEN (National System for Management of Genetic Heritage and Associated Traditional Knowledge) number is A15FAF3
The samples were collected within the National Surveillance System for Influenza viruses
individual identities have been safeguarded by ensuring that personal data
is presented in aggregate or averaged for relevant identifier categories
Information on sex and/or gender has been maintained in compliance with the study’s sex and gender reporting policies
Each clinical sample was inoculated in Madin-Darby Canine Kidney (MDCK) cell culture in the Biosafety Level 3 (BSL3) laboratory
MDCK cells were seeded at a density of 2.0E + 5 per well in a 24-well culture plate and incubated for 24 h in Dulbecco’s Modified Eagle’s - Medium (DME-M) supplemented with pen-strep and 10% Fetal Bovine Serum (FBS)
The viral inoculum was prepared by mixing 200 µL of the original clinical sample with 100 µL of an inoculation medium constituted of DMEM supplemented with 2% bovine serum albumin (BSA)
and 0,1% TPCK (N-tosyl-L-phenylalanine chloromethyl ketone) trypsin
MDCK monolayers were washed once with Phosphate Buffered Saline (PBS) and once with inoculation medium
Inoculum was then added to cells and incubated for one hour at 37 °C
and cells were cultured in the inoculation medium described above for up to 72 h or until cultures displayed evidence of cytopathic effect
which uses the IAV universal primers for the amplification of the eight gene segments of all influenza subtypes in a multiplex reaction
the library was constructed using the Nextera XT DNA Library Preparation Kit (Illumina) and submitted to sequencing by the Illumina MiSeq System using MiSeq Reagent Kit v2 Micro (300 cycles
Illumina) to achieve an estimative of at least 3000x depth of genome coverage
Conventional Sanger sequencing was also used in some cases due to the low coverage observed in some genes
The first round of PCR was performed using the universal primers and a second round of PCR using HA gene specific primers was performed according to the CDC protocol (available by CDC under request)
the DNA fragments were purified using the ExoSAP-IT™ PCR Product Cleanup Reagent (Invitrogen) and quantified by Qubit™ dsDNA HS Assay Kit (Thermo Fisher Scientific)
The products were then sequenced using the BigDye Terminator v3.1 Cycle Sequencing Kit (Thermo Fisher Scientific)
and the DNA products were read by a 96-capillary 3730xl DNA Analyzer (Thermo Fisher Scientific)
The bioinformatics pipeline for assembling the reads and obtaining the consensus was carried out by the CLC Genomics platform (Qiagen)
reads were mapped against a database containing all IAV available references (a panel including around 120 influenza genomes from different subtypes)
the genes with the best score of reads were selected to be mapped
at this point just genes with the highest number of reads were mapped
and then the consensus was retrieved for further phylogenetic analysis
and sequences were removed when: (i) presented a mixed serotype
(ii) data with “lab” or “laboratory” in the host record
(iii) sequences with more than 5 ambiguous bases
and (iv) sequences with less than 75% of the total alignment size
This process resulted in 11 discrete datasets: H1pdm (1 A.3.3.2 lineage; 2851 viruses)
H1hu (pre-2009 human seasonal virus-like or 1B lineage; 374 viruses)
and the 6 internal gene segments: PB2 (2378 viruses)
Each data set included swine and human IAV sequences isolated within the period from 1969 to 2023
The objectives of the epidemiological investigation were to describe the events in terms of person
and place; to identify potential causal factors contributing to the case
and to provide evidence-based recommendations for prevention and control measures
The strategies used for the investigation included videoconferencing with local surveillance to discuss the case
and establish the necessary following steps
which involved interviewing the infected individual and/or their family members
A search for the contacts of the index case
and healthcare professionals who remained in the same ward and attended to the case was conducted
all records of ILI treated during the investigation period (1 month before and 1 month after the onset of symptoms) were surveyed to identify potential cases that meet the case definition
whether or not they have undergone sample collection for detailed investigation
SARI positive cases for IAV were used to survey the circulating respiratory viruses among the residents of the municipality or region where the case occurred

João Resende-Santos
an associate professor of international studies
has been honored with a 2024-2025 Fulbright U.S
a highly competitive and prestigious academic fellowship offered through the U.S
Resende-Santos will spend part of the upcoming academic year at the LusoGlobe Research Center at the University of Lusófona in Lisbon
examining newly declassified archives for his forthcoming book on U.S
foreign policy in response to the decolonization of Portugal’s African colonies from 1950 to 1975
“The Fulbright fellowship is one of America’s oldest programs for international cultural and educational exchanges and I’m honored to join its global network of scholars,” he says. Crediting colleague Juliet Gainsborough, a professor of political science and chair of Bentley’s Global Studies department
for her steadfast support throughout the application and selection process
Resende-Santos observes that participating in the Fulbright Program is particularly meaningful given his academic discipline
which were established in 1976 to foster peaceful relations between America and other nations
constitute an “overlooked but important dimension of U.S
foreign policy and its so-called ‘soft power’ influence in the world,” he explains
I’m honored to now become a part of it.”
response to the liberation movements of Portugal’s African colonies — today the independent nations of Angola
Cape Verde and São Tomé and Príncipe — his Fulbright project “examines a neglected but significant chapter in U.S
policy during the Cold War,” Resende-Santos explains
Noting that decolonization “sparked one of the longest proxy wars in history” between America and the Soviet Union
he says the political realities of Lusophone (Portuguese-speaking) Africa “compelled the U.S
to choose between commitments to military allies like Portugal versus the aspirations of Black liberation and independence ..
[and] represented the broader collision between U.S
policy and revolutionary nationalism in Africa and the Global South.”
Resende-Santos is grateful that his Fulbright Award will enable him to access newly declassified documents reflecting Portugal’s perspective on decolonization
impact and outcomes — by viewing it from the outside in,” he says
“As declassified materials and archives become available in foreign countries directly involved in major Cold War events
we have a unique opportunity to contribute to a fuller understanding of U.S
an honor society for first-generation college students
and was recently recognized by students in Bentley’s Honors Program with the 2024 Arts & Sciences Honors Faculty of the Year Award
Resende-Santos is active as a policy practitioner and international consultant in economic development
trade policy and entrepreneurship and has worked with the United Nations
African Development Bank and the World Trade Organization
Believing that the African Diaspora has a role to play in promoting development back on the continent
he continues to be actively involved in educational and policy activities in Cape Verde.
I'm from Portugal
and was looking for jobs in scientific writing
the US seemed more promising for my career
I missed the laid-back pace and work-life balance back home but enjoyed the energetic vibes of Memphis and the hustle culture
where I felt like I was growing in my career
There was one unfortunate experience I'll never forget that changed how I see the US medical system and the way I seek medical care
I was feeling intense and worsening abdominal pain for about two weeks
so I went to my US doctor who advised me to go to the ER
I'd never been to an ER in the US before and didn't know what to expect
After my biopsy results came back showing the mass wasn't cancerous
I decided to go to Portugal for a second opinion
I spoke with three separate oncologists and two general surgeons
the oncologists confirmed that the mass in my abdomen was benign
I was treated at a private hospital in Portugal
All my exams plus treatment cost me about $380 — less than a quarter of what I was charged at the US ER just for exams
The experience caused me extreme stress for months
I received my biopsy results six days after leaving the hospital indicating the mass was not cancerous
but I was already so afraid of the possibility of it being cancer that I wasn't able to calm down until months later after I'd consulted multiple doctors in Portugal who confirmed the diagnosis
This is why I've decided to fly back to Portugal once a year to complete all of my medical needs including regular and specialized check-ups
I continue routine check-ups with my family doctor in Portugal
Specialized check-ups are also free as long as my family doctor recommends them
Despite my unfortunate healthcare experience
I believe the overall quality of life in the US is superior to Portugal's and I intend to continue living here
and there are endless opportunities for career advancement that simply aren't available in Portugal
with higher salaries and the freedom to explore different cities without major language or cultural barriers

Lawyers love legal theories. President Trump’s unprecedented executive actions have reignited interest in theories about the U.S
Is he working with an extreme conception of the unified executive theory
a strong version of “originalist” or even “post-originalist” legal reasoning
or will the “political question doctrine” dominate
Because Trump’s supporters are not deploying them in good faith
these theories are being used as rhetorical maneuvers to dress up a power grab in theoretical garb
I am sure of that for a simple reason: Trump’s backers invoke these theories only to defend Trump’s actions
When Biden used the powers of the Presidency – and perhaps overstretched them – Republicans regularly brought him to Court and celebrated each and every decision against his administration
Not once did they argue that the Supreme Court erred because Biden
should operate under the unified executive theory or any other legal construction that would grant the President massive powers
Trump’s supporters use the theory only when it serves them
operated under extensive assumptions of presidential power – and were often stopped by the Supreme Court
presents the most extreme case of such overreach
When a party advances a theory only when it is useful to them
it is not a theory: it is a thinly veiled attempt to legitimize actions
A theory about the American Constitution (or any other) should apply regardless of who is in power
That is a fundamental premise of the rule of law that underlies the democratic state
The fascination with such theories is not limited to lawyers
Many political scientists insist that “populists” are against checks and balances and favour raw forms of majoritarian rule
They take the momentary justifications of authoritarian actors at face value rather than examining their overall record
Take the authoritarian Polish Law and Justice Party
it made much about the will of the majority
invoking it to destroy Poland’s rule of law to appoint its own people to courts
it stopped talking about the majority will and invoked the rule of law and the judgements by courts it had captured to slow down the new government
the party seemingly transformed overnight into a “liberal” party in love with checks and balances
happy to use any constitutional argument that serves its interests in a given context
My plea is this: constitutional theories are interesting and important
You may not agree with the unified executive theory
but they are not inherently absurd propositions
They are worth discussing – just as other approaches – if they are genuinely intended to apply to any presidency
it makes no sense to present any of them as the theory of the Republican Party – or of Donald Trump – because neither has ever thought it was a general theory for the American presidency
There is no good-faith theory underpinning the administration’s actions
It simply grabs power because it can – until someone stops it
Which brings us to the role of the Supreme Court
When adjudicating cases involving overreach by the Trump administration
the Court should question the parties to the case about their good faith in advancing constitutional theories
but the credibility of the parties lends weight (or not) to their arguments
Many decisions by the Trump administration and its agencies will raise the same question: How much regulatory authority do they have in the absence of clear congressional legislation
And Trump will face the reverse question as well: Can the president act unilaterally
even if doing so violates rules clearly established by Congress
Are executive orders invalid if they violate such rules
And what about actions like the de facto dismantling of a congressionally mandated agency like USAID
Will the highly polarized Supreme Court apply its theories and precedents to the cases before it without fear or favour
And if the Supreme Court reins in Trump’s power grab
Analysts say that failure to comply would result in a full-blown “constitutional crisis” (The Economist)
is overly generous to the Trump administration
it should be described as a coup – and the end of the US Constitution

Jason Michael Perry joined as the senior advisor for corporate technology and innovation
and is spearheading the growth of two signature programs at WTCI – the AGILE Global Innovation Series and the Maryland Innovation Lab
He has extensive experience in designing and engineering digital solutions for businesses with a focus on AI and emerging technologies
in partnership with the Maryland Department of Commerce
a program that pairs global startups with Maryland-based companies to identify innovative solutions to challenges
It is part of the state’s $2 million Global Gateway Program
which helps attract more international businesses and eases the transition into the U.S
market by connecting them with local incubators and accelerators
The Maryland Innovation Lab is based on a model developed by the United Kingdom’s L Marks
where corporations are matched with global startups in a 10-week accelerator
The lab's goal is to help corporations bring in new talent and ideas to scale innovation without the in-house expertise needed to run an accelerator program
“We had 600 startups apply for our first cohort,” says Resende
nine were invited to pitch their product before three were selected
This is an opportunity for Maryland to expand inbound foreign investment and attract startups to establish a location here.”
The first cohort focused on sustainable food systems with corporate partners Sodexo US
the startups deployed several disruptive solutions including a seaweed-based alternative to fossil-fuel plastic packaging
the first sensorless behavioral AI software for retailers and fast-moving consumer goods
and a blockchain-based traceability solution for sustainable food supply chains
The program is preparing to launch a second cohort focused on revolutionizing logistics and strengthening supply chains
population living within an overnight drive
Maryland offers unmatched access to major markets
and the Port of Baltimore is a leader in cutting-edge infrastructure and technology
While the Maryland Innovation Lab is a new program for WTCI
the AGILE Global Innovation Series began 10 years ago when it explored the innovative approach of a featured company
the program is evolving to focus on a specific topic and foster dialogue among several leading companies in the state to share powerful personal stories and experiences that inspire executives to face challenges head-on
the program recently relaunched to provide members with access to experts who will address topics of concern related to tech innovation
took place in November and featured three panelists: Seema Alexander of Virgent AI; Alex Goranin of Duane Morris; and Steve Shapiro of Prometric
“Jason is our partner for all things tech
who is helping us elevate and grow our tech and innovation expertise and expand our programming,” Resende said at the November AGILE event
Empowering Global Disaster Response with Technology
will take place February 18 at Johns Hopkins Carey Business School
The yet-to-be-announced panel of experts will explore how technology is transforming disaster relief worldwide
from drones delivering aid to satellite communications supporting remote areas
WTCI continues to be the leader in connecting and informing businesses and leaders interested in learning more about the global marketplace
It has created a library of content for members
and has launched a podcast that explores international news and features conversations with member companies

What makes them so special? Here's who won best Cape Verdean restaurant in Brockton
How the business startedResende began her career after becoming a registered nurse during COVID-19
which completely burnt her out and she was itching to start something new
she was working in California as a travel nurse
living with her fiancé and business partner and their children
The idea of switching to the beauty aspect of nursing seemed like a dream come true

'Drip Queen' Hungover? Brockton nurse makes IV injection house calls
A quick turn of events“Once I started taking my courses
I fell in love and became obsessed with the aesthetic industry
I knew working in the ICU was the first step that got me through the door
I always dreamed of becoming an entrepreneur,” Resende said
The young nurse grinded her way to the top and followed her new aspirations and with the support of family and friends
Resende suffered several tragedies in life
but it made her want to invest time and effort into something that will flourish
As a first-generation Cape Verdean American Resende is living “the American dream” but in her own way
“The American dream right now is so hard even as a working nurse
Being with my fiancé for almost twenty years and meeting at BHS and having kids young
we were expected to fail statistically speaking
but we always had such big dreams and never stopped dreaming,” Resende said
One of the best lessons the spa owner learned on her journey is that “you’re responsible for your failures and successes
There’s no one looking over your shoulder to make sure you’re hustling.”
the business has been open for a few months and hopes to expand and be a staple in the beauty world on the South Shore

Syria is facing massive political upheaval after the fall of dictator Bashar al-Assad
How do questions of transitional justice relate to building a functioning state
And what role will international actors play in the political transition process in the months ahead
Executive Director of “Democracy Reporting International” (DRI)
an international NGO headquartered in Berlin that has extensively supported constitutional reform processes in the Middle East and North Africa
global attention is now focused on the country’s political future
international legal advisors have often been quick to propose grand concepts such as federalism or presidential/parliamentary democracy following major state upheavals
I hope that such questions will come into play and that the country does not descend into another civil war
has somewhat stabilized in recent years despite many expectations to the contrary
Anyone who wants to support a peaceful process must understand that negotiating political solutions is an extremely sensitive process
Syrians must deliberate and make decisions themselves
International organizations and NGOs can help ensure that they receive good comparative information
This often includes Syrians who work on these issues within international organizations and NGOs
foreign observers are often quick to propose simplistic solutions
Syria is a relatively large and highly heterogeneous country that fears concentrated power
Then federalism must be the ideal solution
Labels like federalism often evoke different associations than we might imagine
often has the reputation of being a precursor to state collapse
raising fears of the secession of federal states
A term like federalism can immediately harden negotiations
Syrians must negotiate what kind of state they want to have
What powers should be vested at what level and in which institution
It is not important how solutions they find might be labelled
What matters is that all relevant groups are involved and that there are viable
functioning compromises that have broad support
Syria has had a new constitution since 2012
but its content and drafting process were sharply criticized by opposition groups
Does this constitution play a role in the country’s political future
or will the priority now be to quickly initiate a new constitutional drafting process
Assad drafted a new constitution in the context of the rebellion
It was meant to appear as a concession to the people but it further expanded his power
The referendum on the constitution was widely boycotted
The Syrian opposition demands the drafting of a new constitution
the new Hay’at Tahrir al-Sham (HTS) government currently gives the impression of a managed transition rather than a revolution
It recently announced that it would “suspend” the constitution and parliament for three months
with a committee tasked with reviewing how the constitution can be adapted
I believe we are at a crossroads: either the new government will adjust the constitution executively (and possibly attempt to quickly legitimize it through a referendum)
or it will use the three months to outline a more nuanced reform process that involves all relevant groups and includes the drafting of a new constitution

You mentioned that we are observing more of a managed transition than a revolution
personnel continuity play in transitions like the one in Syria
The Bush administration’s decision to dissolve state institutions triggered the collapse of the state
HTS secured support largely by ensuring that the zone functioned administratively and economically to a reasonable degree
It achieved a kind of “output legitimacy” there
It is possible that HTS views the issue of continuity pragmatically
leaning toward the mentioned “executive solution.” On the other hand
it has also announced that “all those who have committed crimes against the Syrian people will be prosecuted under the law.”
many soldiers and officials from the Assad regime could be prosecuted
only high-ranking individuals might be targeted
isn’t there a tension with issues of transitional justice—that is
addressing the injustices and atrocities committed during the dictatorship
this tension is very strong and always exists when dictatorships fall
there is a need to maintain the functionality of the state; prosecuting many soldiers and officials could weaken that functionality
The destruction in Syria is immense—half the population has been displaced
If ever a functioning and pragmatic state was needed
the Assad regime was among the most brutal governments in existence
There is now extensive reporting on the Saidnaya prison
which has long been a nightmare for Syrians
This slaughterhouse is just the tip of the iceberg of a heinous regime
Who are we to tell Syrians whose families and friends were tortured and murdered that they should forgo justice
Only Syrians can negotiate this among themselves
How far do they want to go with prosecutions
Should they address the issue through non-criminal institutions like truth commissions
morality is not solely on the side of justice
The functionality of the state and its ability to solve problems also carries a moral dimension
Let’s briefly touch on international law and geopolitical interests in the region
Some states have proposed basing the political transition process on UN Security Council Resolution 2254
which outlined initial elements for a political process after the civil war
and could it play a role in the power transition in Syria
Since the Assad regime violently suppressed protests and the situation escalated into a civil war
the United Nations and many states have made intensive peace efforts
including numerous studies and proposals on what a new Syrian state could look like
many of which were developed by Syrian experts
This could now be an advantage if the HTS government opens up to them
there was hope for an agreement between the regime and the opposition
UN Resolution 2254 provided a legal framework for those talks
as it no longer aligns with current circumstances
It was intended to broker peace between the regime and the opposition
The regime no longer exists as an organized force
rendering that part of the resolution irrelevant
as it establishes key pillars for a potential process
This is reflected in yesterday’s G7 declaration
which pledged full support for an “inclusive Syrian-led and Syrian-owned political transition process” in the spirit of UN Resolution 2254
Foreign actors must act with sensitivity but should also articulate their positions and interests
Take Germany as an example: Germany has provided immense support to Syrians in need (and also benefited
considering issues like brain drain and addressing labor shortages)
The German judiciary decided the first-ever case related to state torture in Syria (the “Koblenz case”)
Over a million people in Germany are either Syrian or of Syrian descent
The situation in Syria directly affects us
Germany has the right to demand something from the new government—primarily an inclusive process
The German government should insist on this and make its support for reconstruction conditional upon it
It is positive if the new government wants to solve problems quickly
but it must also dedicate time and energy to involving all major Syrian groups in the reform process
This type of “input legitimacy” is crucial for long-term stability
especially regarding sensitive issues like state structure and individual rights
What is needed now is not megaphone diplomacy but rather dialogue with the government and all other groups
The Wind Knows My Name by Isabel Allende weaves together the stories of two children—one in 1938 Europe and the other in present-day America—whose lives are shaped by the trauma of family separation
is put on the Kindertransport to England by his mother in a desperate attempt to save him from the Nazis
is forcibly separated from her mother after they seek refuge in the United States. Allende artfully connects these two historical episodes to capture the cruelty and emotional trauma that experiences of flight and loss inflict
resistance and compassion that persist in the face of state-sanctioned violence.
the Romanian Constitutional Court annulled the first round of the presidential elections
The decision has sent shock waves through Romania and Europe
and it does not only have domestic implications but potentially also geopolitical dimensions
The court’s intervention was prompted by evidence of Russian interference in the electoral process and campaign
There are therefore many reasons to make the events in Romania a focal point here as well – and that is precisely what we have done:
and face value are such that it risks shooting Romanian democracy in the foot
The gravity of the interference in Romania’s elections implied a need to intervene quickly
the decision could prove counterproductive
While the German Supply Chain Act faces criticism for its potential economic impact, compliance offers companies significant advantages. SARAH MASOUD (ENG) argues that amending or repealing the German Supply Chain Act risks diminishing these advantages for German businesses
Almost immediately after the fall of the Assad dictatorship, German politics began discussing forced returns to Syria. However, legally and practically, the situation is more complex than some suggest. DANIEL THYM (GER) outlines the legal framework of the current discussion
AGNE LIMANTÉ and YULIIA MOSKVYTYN (ENG) examine Ukraine’s recent steps toward AI integration in the courts
highlighting initiatives and plans for the future
While these efforts reflect a growing recognition of AI’s potential
are just as significant in judicial contexts as they are in other areas
In Croatia, a conflict between the European Public Prosecutor’s Office and the Croatian Anti-Corruption Bureau is escalating. The European Public Prosecutor’s Office is now accusing Croatia of systematic rule of law deficiencies. TIM HUYENG and SINAN KURT (GER) highlight that the Croatian population increasingly views the EU as a guarantor of the Croatian rule of law
it could establish a completely new type of agreement
as the accord pioneers and demonstrates mechanisms that could transition trade law into a new era of sustainability law
The AfD is also increasingly represented in local councils. The party tries to present itself as a caretaker party while simultaneously playing a significant role in damaging public discourse. This poses a serious threat to democracy and a diverse society, observe ANNA-SOPHIE HEINZE and BENJAMIN HÖHNE (GER)
the minority coalition was able to reach an agreement with the Left Party at the last minute

The sudden enhancement in the mesospheric neutral metal layers (Ns) has been studied in different latitudes for decades
Sodium Ns layers have been analyzed since their first observation at the end of the seventies
Several studies have reported Sodium Ns during events of energetic particle precipitation (EPP) and the formation of auroral-type sporadic E (Esa) layers at high-latitude stations
The Esa layers are also observed in the Brazilian low-latitude sector during the EPP events due to the South American Magnetic Anomaly (SAMA)
despite extensive studies on the SAMA region
no reports exist about the co-occurrence of the Ns layer and the Esa layer
we observed on 26 April 2023 a peculiar Ns layer event synchronously occurring with the development of the Esa layer in the SAMA region
They showed that Ns layers were observed in more than 88% of nights
reaching an average peak density of 300 and 6,000 atoms cm−3
the authors showed that the strongest layers
have peak density higher than 500 (10,000) atoms cm−3 K (Na)
the averaged peak height around 92 km (94 km) for K (Na) and often have a downward movement in the peak density height
it is stablished that a metal ion first form an ion-cluster
Na+ + N2 + M → Na.N2+ + M (M = third body)
then this ion-molecule undergoes a dissociative recombination with an electron and finally releasing the metal atom
According to their laboratory experiments and modelling
descending Es layers which are major formed by metallic ions
can produce Ns layer bellow 100 km by ion-molecular neutralization mechanism
The authors suggested that the pitch angle scattering driven by hiss waves triggers the dynamic mechanism responsible for the low-energy electron precipitation over the SAMA region that generates and maintains the Esa layer in this low latitude during the recovery phase geomagnetic storm
the authors suggest that the signature of this atypical Esa layer in the Brazilian sites could be used as an indicator of the occurrences of the low-energy electron precipitation over the SAMA region
it seems this event refers to a peculiar Ns layer
Ns layer observed in the height-time-intensity plot of (A) K and (B) Na layers on 26 April 2023 over São José dos Campos
The local time at this site is given by LT = UT−3 h
The suggested theories for explaining the Ns layers formation can be grouped into three categories: (i) injection of fresh atomic metals by meteoric ablation; (ii) vertical redistribution of atomic Na from the background layer; and (iii) in situ production of atomic metals from a reservoir species
there are compelling arguments that lead us to reject the (i) and (ii)
Direct meteoric ablation to produce the observed Ns layer characteristics
would requires large meteoroids and/or a strong meteor shower
no fireball nor significant meteor shower was observed on the night in question
the present observation of the increases in the total column abundance
clearly indicates that Na and K are formed from a fresh source of Na

The white isolines indicate the SAMA region (23,000 nT)
The red isolines indicate the Quasi-Dipole latitudes from −40° to 30°
Following Da Silva et al. (2022), we used their empirical model to verify the agreement between the extra ionization measured by Digisonde and those produced by low-energy electron precipitation. These simulations are based on the work of Fang et al. (2010) and all parameterizations used in the calculations are well detailed in Da Silva et al. (2022)
Figure 5. Estimated parameters for Cachoeira Paulista station at 07:00 UT according to the empirical model proposed by Fang et al. (2010)
(A) Estimated total incident energy of electrons between 100 eV–tens of keV
(C) ionization rate altitude integrated and (D) frequency range altitude
ΦM: Differential number flux (cm−2 s−1 keV−1)
Q0: Total energy flux (keV cm−2 s−1)
The normalized energy dissipation (f) is expressed as follows (Fang et al., 2010):
The next step is obtaining the ionization rate profile [P(z)] by summing up qtotz at each altitude
Thus, we obtain the rate of ion (and electron) production (P). The difference between this term and the rate of loss (L) provides the time variation of electron density (Ne), as indicated by the well-known continuity equation. The Ne (electrons cm−³) is associated with foEs (MHz) as given in Equation 3 by Ratcliffe (1959):
The critical ionospheric frequency is the highest cutoff frequency at which the ionosphere layers reflect electromagnetic waves (Kumluca et al., 1999)
Figure 6. Ionograms from the ionosonde located at Cachoeira Paulista. (A) Beginning of extra ionization at 06:40 UT. (B) Esa layer at 07:00 UT overplotted the estimated critical frequency. (C) Esa at 07:20 UT overplotted the estimated critical frequency. The blue line refers to the critical frequency (MHz) estimated by empirical model (Fang et al., 2010)
Combining the scenario in the inner radiation belt, shown in the ARISE satellite data and the observations of the nighttime Esa layer over CXP and E layer over CG and CXP, both sites within the SAMA region, additionally with the good agreement between the ionization measured and those calculated (Figure 6) supported that EPP event occurred during the observations of the Ns metal layers as shown in Figure 1
This simplest comparison agrees with concomitance Es formation mechanism
caused by tides and extra ionization due to EPP
this last mechanism can be used to explain the present high density of Ns layer
in this hypothetical situation the ions moved down to lower altitude (∼92 km)
as the ion-molecule neutralization is dramatically fast in these altitudes
the time resolution of Digisonde (10 min) is not sensitive enough to detect Es
explaining the differences between altitudes of Ns and Es layer seen in the ionograms
a detailed investigation of the possibility of an extra vertical electric field over the SAMA region during EPP can be addressed in future work
EPP event in the SAMA region can trigger some metal atoms to be released from such or other complex chemical reactions
never thought to be possible in lower latitude region
it is well known that the EPP increases the NOx and OHx in the mesosphere
which has an important role in the reduction of [O3] concentration
and the O3 is one important constituent to the Na and K sink reactions in the MLT region
This would imply in an increase the lifetime of these metal atoms in the MLT region during EPP events
could be explained by the dynamic consequence caused by the advection
This effect can occur because the LIDAR’s beams are narrow and pointed vertically; thus
a descending layer can produce a virtual effect of ascending development when it crosses the LIDAR’s Field Of View (FOV)
imagine a pre-existing Ns layer with a downward structure and horizontal movement that passes through the sky over the LIDAR station
The LIDAR will first record the atoms at the bottom of this layer and then the higher ones
The effect produced in the Lidargram will be an ascending structure event from a pre-existing downward Ns layer advected horizontally through the LIDAR’s FOV
this is unlikely when considering the good correspondence between the starting time of atypical E layer
and the substantial enhancement in the neutral metal layers
Since the plasma density in the Esa layer increases with altitude
the metal ions are expected to follow the same behavior in the vertical profiles
their neutralization will also obey this vertical distribution
increasing the concentration of neutralized atoms with altitude
the EPP can also contribute to release metals in different altitudes that can influence the pattern of Ns layer
Combining these effects can help us to understand the ascending behavior of the Ns layer
Although our results have provided substantial evidence supporting the existence of EPP
the Eulerian effect due to advection is also a possible explanation for this behavior
The occurrence of the Esa layer and the nocturnal E-region within the SAMA region is strong evidence of the EPP event
Even though more efforts are needed to elucidate the coupling mechanisms between magnetosphere-ionosphere-mesosphere systems
the present work shows evidence of a neutral atmosphere response to EPP outside the auroral region
although the Ns over the SAMA region have been studied for more than 50 years
there are not any prior reports regarding metal enhancement during the occurrence of the Esa layer yet
the present work opens new discussions about the mechanism responsible for generating Ns layer and the connection between the increase in neutral metals in the MLT with EPP events in the SAMA region
since this is the first observation of such a phenomenon

The disease has a major social and economical effect
negatively impacting the life of the infected individuals
An early and accurate diagnosis is essential for administration of early treatment
prognostic tests may aid disease management
the serological diagnostic scenario for CD still faces several challenges
making the development of new diagnostic kits a pressing matter
several researchers have expanded efforts in developing and testing new antigens
such as recombinant proteins and recombinant multiepitope proteins
These recombinant antigens offer several advantages
such as improved sensitivity and specificity
it has been possible to observe a rising number of studies using ELISA and point-of-care platforms
employing these antigens in the past few years

demonstrating great capacity to discriminate between positive and negative samples
recombinant multiepitope proteins also demonstrated an improved diagnostic performance
a great number of studies employing these antigens showed sensitivity and specificity values above 90%
it is still possible to observe some bottlenecks in the development of new antigens
such as the scarcity of tests with sera from the acute phase and the variability of results in different geographic areas
aiming to contribute to control and health programs
the continuous search for a more accurate serological diagnosis is essential
both for the acute and chronic phases of the disease
Due to the promising application of recombinant antigens in CD diagnosis
the aim of this review is to discuss studies that used recombinant antigens for CD diagnosis
The use of diagnostic technologies with recombinant antigens is a promising strategy for CD diagnosis, given that these antigens improve sensitivity and specificity of a serological diagnosis.

aside from not presenting false-positive results when analyzing T
the need to confirm the disease through at least two serological tests generates more costs to the public health system
there is an urgent need to develop new diagnostic tests to detect the disease in the chronic and acute phases
primarily associated with statistical programs to calculate the sample number and obtain more reliable results
most of the studies mentioned above used a small sample size
requiring new studies with broader testing
the development of new specific diagnostic kits for both the acute and chronic phases is seen as essential
The vast majority of above-referenced studies used sera from the chronic phase in their tests
It could be hypothesized that the low-level testing of acute phase sera is linked to the lack of access to sera from individuals at this stage
considering that endemic areas are usually developing countries that have limited access to information and health and medical services
the symptomatology in this phase is not specific
which may contribute to delays in seeking medical care at the onset of the disease
making an early and specific diagnosis difficult
Some measures must be taken into consideration when developing new CD serological tests
it is essential that one use low-cost reagents
designed for better accessibility and more widespread testing
the development and implementation of rapid tests are essential to providing a rapid and reliable diagnosis
even in remote areas where access is difficult and nearby specialized laboratories are scarce
could simplify testing as they are less invasive
The need to improve ELISA techniques should also be highlighted
aimed at providing more accurate and reproducible diagnoses
the development of new biomarkers that could allow monitoring the disease progression would greatly assist in clinical decision-making
it is also necessary to strengthen bonds between public and private research with the public health system
It is known that better control or even eradication of several diseases
will probably only be possible with collaborations
whether between researchers or between research and the public health system
aiming to establish a more practical and accurate diagnosis for the disease
more incentives from government agencies are needed to encourage as well as facilitate research
strengthening bonds and creating a bridge between innovation and the implementation of these innovations
this review affirms that the use of recombinant antigens has shown encouraging results when it comes to the need for a better CD diagnosis
there is need to conduct ongoing studies in search of new antigens to develop faster

This article is part of the Research TopicEmerging Swine VirusesView all 14 articles
Next generation sequencing (NGS) can be applied to identify and characterize the entire set of microbes within a sample
this platform does not provide a morphological context or specific association between the viral or bacterial sequences detected and the histological lesions
This limitation has generated uncertainty whether the sequences identified by NGS are actually contributing or not for the clinical outcome
Although in situ hybridization (ISH) and immunohistochemistry (IHC) can be used to detect pathogens in tissue samples
only ISH has the advantage of being rapidly developed in a context of an emerging disease
especially because it does not require development of specific primary antibodies against the target pathogen
Based on the sequence information provided by NGS
ISH is able to check the presence of a certain pathogen within histological lesions
helping to build the relationship between the pathogen and the clinical outcome
In this mini review we have compiled results of the application of NGS-ISH to the investigation of challenging diagnostic cases or emerging pathogens in pigs
that resulted in the detection of porcine circovirus type 3
in situ hybridization assay allows the detection of nucleotide sequences in histological sections without requiring the development of such antibodies
Tissue-based diagnosis is undeniably one of the most important approaches for the identification of a potential role of the pathogen as the etiologic agent of that disease. The histological lesions recognized by the pathologist can be associated with the presence of a given pathogen detected by immunohistochemistry within the lesions (4)
production of a sensible and specific antibody and the optimization of the immunohistochemistry protocol can take several months
delaying effective actions to control a particular emerging disease
This mini-review focuses on the development and application of a new platform of diagnostics that combine next-generation sequencing and in situ hybridization for investigating unsolved diagnostic cases in swine
Sequence technologies have risen in the past few years as a meaningful ancillary tool for diagnostic investigation of infectious diseases. Next generation sequencing (NGS) is one of the most recent sequencing approaches included in the range of diagnostic methods for veterinary diagnostic investigations (6–8)
The NGS advantage in relation to simple sequencing relies on a de novo or mapping assembly of sequenced regions
dismissing the use of specific targets to build a complete genome
genome fragments of virtually all the microorganisms present in the clinical samples are sequenced and then
re-assembled based on genome data bases publicly available
These characteristics of NGS make it very convenient for investigation of infectious disease outbreaks in which the etiologic agent is unknown
NGS lacks the association of the presence of a microorganism and the type of histological lesion
Since the development of specific antibodies for immunohistochemistry requires a long period of time
there was a demand for a diagnostic method that would allow the association of the genomes detected by NGS with a tissue lesion
Workflow for diagnostic investigation of unsolved cases using next-generation sequencing and in situ hybridization
The years of 2014 and 2015 were marked in the swine industry of the USA, Canada, China, and Brazil by outbreaks of diseases characterized by vesicular lesions on the coronary band and snouts of sows and growing pigs and acute neonatal pig deaths (22–25)
In addition to the impact of the disease in pig herds itself
the vesicular lesions are clinically indistinguishable from foot-and-mouth disease (FMD) and other vesicular diseases
and a commercial kit for SVA qRT-PCR was developed
It was in 2016 when the new porcine circovirus was found in pigs exhibiting clinical signs similar to the PCV2-associated diseases
it was noted that lymphoid depletion is not a characteristic of PCV3 infection
These results highlight the challenges for interpreting PCR results when animals are positive for PCV2 and PCV3 and reinforce the need of qualified pathologists to interpret the histological lesions and the possible association with the agent identified by NGS
These results represent an important advancement for understanding the potential role of PPV2 in emerging systemic syndromes in nursery and finishing pigs
and reemerging diseases have increased in the past few years
Traditional ancillary tests are routinely used to investigate the involvement of known pathogens when samples from outbreaks are sent for diagnostic investigation
one of the characteristics of traditional ancillary tests is that they are designed to detect known pathogens
The association of NGS-ISH has been instrumental on the investigation of etiologic causes of cases in which the traditional ancillary tests did not identified involvement of known pathogens
one of the most important diagnostic laboratories for swine infectious diseases in the US
is a pioneer in using NGS-ISH as a tool investigate possible emerging diseases
as happens to new technologies are being implemented and optimized
faster and more assessible to non-research purposes
it is still a technology that requires structured laboratories
qualified professionals to interpret the relevance of the several microorganisms' sequences identified by the sequencing in the swine samples
ISH helps to determine whether the virus is metabolically active within lesions
the approach relies on targeting a mRNA that corresponds to the DNA sequence identified by the NGS
If the chosen DNA sequence is not been translated in mRNA
the absence of positive signals can mean a false negative
ISH method used in combination with NGS it is still relatively expensive due to dependency on a single manufacturer that detains the intellectual property of the ISH technique
we anticipate that the in the next few years both the demand for best diagnostic approaches for emerging diseases will stimulate both methodologies to evolve in regards of their feasibility and costs
making the NGS-ISH an important tool for identifying pathogens in swine emerging diseases
the NGS-ISH diagnostic platform presented here combines the comprehensive unbiased detection of nucleic acid sequences with the morphological context shown in the histological lesions
This characteristic has been specifically important to diagnose infectious diseases in which the clinical and laboratory findings are not able to specific determine the primary pathogen involved in the clinical outcome
the ability to detect sequences from previously unknown agents through NGS allows the design and subsequent identification of emerging pathogens within tissue sections
This rapid diagnostic response is critical to implement control measurements and mitigate economic losses in the swine industry

EXCLUSIVE: The agency has brought in McKay Hathaway from VML as SVP
creative and has elevated Nat Resende to ECD in Chicago
Digitas is shoring up its creative talent bench
bringing on McKay Hathaway from VML as SVP
creative and elevating Nat Resende to executive creative director of the Chicago office
Hathaway had been an executive creative director at VML since 2017; prior to that
he was an associate creative director at MullenLowe
most recently as SVP and group creative director.
Resende has worked on an international CPG client
bringing increased cultural relevance to its portfolio of brands
modern and global-minded sensibility to our work and our collective vision,” said Shah
adding that her willingness to consult other teams at the agency and as well as clients is “increasingly important” as the industry feels the “compounding pressures of doing more with less.”
Resende has also been a key driver in incorporating AI into the creative process and briefs
which is where we’re wanting to go as an agency,” she added
Hathaway steps into Resende’s previous role
where he was the executive creative director leading the integrated Wendy’s account.
Shah described Hathaway as a “true maverick in the shaping of brands for new worlds,” calling his work for Wendy’s “rule-bending” and “such an inspiration.”
Shah noted his ability to innovate how Wendy’s appears in emerging online spaces such as gaming
pointing to Hathaway’s role in campaigns like Keeping Fortnite Fresh and the Wendyverse on Horizon Worlds as examples of his “natural cross-platform fluency.”
Digitas is purposefully bolstering its creative leadership team with talent that understands the power of tech as it further invests in the space; it introduced its own generative AI operating system and tool suite
Lanzi said the creative team’s use of AI tools is “focused on creative intelligence and how that makes our brands and our creatives inform our clients how they should be investing intelligently.”

The Appeals Court rejected Resende's argument that he had ineffective counsel when a jury found him not guilty of killing Brockton's Nelson Pina
two previous convictions for robbery during the same incident remain on the books.
"To the extent his current argument varies from his arguments on appeal
we discern no miscarriage of justice," the Appeals Court justices wrote in a May 13 ruling
Plymouth County District Attorney Tim Cruz applauded the decision in a Thursday statement
"This is a just conviction and we only hope that Mr
Pina’s family find peace and will no longer be further victimized by these meritless claims," said Cruz
"Jaime continues to be as upbeat as he always is and says to remind everyone that this is just another step."
Resende's defense team asked the Appeals Court to reconsider its decision
In a motion filed Friday, May 27
LaCivita argues that the lawyer representing Resende when he was found not guilty of murder should have pushed to have that acquittal apply to the underlying charges of attempted armed robbery and unarmed robbery
"It was a gross and material failure for Attorney (Jonathan) Shapiro to stay silent following the NOT GUILTY verdict on February 13
"Due directly to Shapiro’s failure to advocate for his client in that moment
Resende remains unlawfully imprisoned."
Crackdown: Here's how Brockton is cracking down on illegal fireworks ahead of start of summer
Appeals Court justices swiftly denied the motion to reconsider
LaCivita said she is working with Resende to apply to the state's Supreme Judicial Court for further appeal
during an attempted robbery of cash and drugs
Police said they found $48,000 cash in Pina's basement
which was illegal at that time. There was also a ledger of what prosecutors believed were drug deals
convicted Resende and Kenston Scott of first-degree murder

Resende's setbacks at court since his second trial include a 2017 decision by the state's highest court
It rejected Resende's argument that he had been placed in double jeopardy
Cruz said he and his office are keeping Pina and his surviving family members foremost in their thoughts
"Our job as prosecutors is to present the facts," Cruz said in the Thursday statement
"A conviction rests solely in the purview of the jury
And we all have a duty to respect the jury’s presence at trial
and deliberations which resulted in a unanimous verdict of guilt of the crimes of Armed Home Invasion and Armed Assault with Intent to Rob Mr
Resende is serving 20 to 22 years on the armed home invasion count
and 18 to 20 on the armed assault with intent to rob count
meaning he's serving time for both of them at once
He is currently at the state prison in Shirley
Resende's cause has attracted support from social justice groups including the D.A.R.R.C. Coalition, which devotes a section of its website to Resende's case
Cruz detailed all the ways courts have denied Resende's appeals
Resende’s challenge to his convictions were reviewed and rejected on appeal by the Supreme Judicial Court
the highest appellate court in the Commonwealth
by Judge Angel Kelly here in the Brockton Superior Court
and I commend them on their thoughtful decision," said Cruz
Brazil – Nissan's Resende Industrial Complex in Brazil is celebrating its fourth anniversary with major production and export milestones
the Brazilian plant welcomed 600 new employees and introduced a new shift
Employees tweaked processes and ramped up production to meet rising demand of Nissan Kicks
the brand's most awarded crossover in the region
major achievements have followed to streamline production for the domestic and overseas markets
the plant celebrates its fourth anniversary
which coincides with the milestone of 200,000 cars made – thus affirming its position as Nissan's key production hub for the Brazilian and Latin American markets
The crossover has been exported to Argentina since January 2018 and was ranked the segment's top selling model in the domestic market last March
With its three locally produced models – the Kicks crossover
as well as the Nissan March hatchback and the Nissan Versa sedan – the Resende Industrial Complex recently surpassed the mark of 30,000 units shipped to overseas markets
Resende also assembles flex fuel engines: a 1.0-liter 3-cylinder 12-valve unit
Both engines contributed to yet another milestone: 200,000 powertrains since the start of operations
More than R$ 3.3 billion (1,692 billion USD) were invested since the launch of the industrial design phase
The comprehensive production process starts at the stamping shop and ends at the testing track
To meet a rise in demand both in the domestic and overseas markets
600 new jobs were created in the last 12 months
and now the Resende Industrial Complex has 2,400 direct employees

This article is part of the Research TopicVertical Coupling in the Atmosphere-Ionosphere-Magnetosphere SystemView all 21 articles
We present a study about the atypical and spreading Sporadic E-layers (Es) observed in Digisonde data
We analyzed a set of days around space weather events from 2016 to 2018 over Cachoeira Paulista (CXP
The inhomogeneous Es layer is associated with the auroral-type Es layer (Esa) occurrence in this region due to the presence of South American Magnetic Anomaly (SAMA)
we also observe that the spreading Es layers occurred days before the magnetic storms or quiet times
this specific type of Es layer has some different characteristics concerning the Esa layer
and meteor radar to understand the dynamic processes acting in this Es layer formation
Our results lead us to believe that other mechanisms affect the Es layer development
We show evidence that the instabilities added to the wind shear mechanism can cause the atypical Es layers
such as Kelvin-Helmholtz instability (KHI)
an important discovery of this work is that the spreading Es layer
is not necessarily due to the particle precipitation due to the SAMA
We found that the wind shear can be turbulent
our analysis better understood the Es layer behavior during quiet and disturbed times
• Digisonde data is used to study the spreading of Sporadic E-layers (Es) over Cachoeira Paulista
• The inhomogeneous Es layer also occurred days before the magnetic storms or quiet times
not associated with the particle precipitation due to the SAMA
• The results show evidence that the instabilities added to the wind shear mechanism can cause the atypical Es layers
Atypical spreading and multiple Es layers can occur in low and middle latitudes ionograms. This Es layer behavior can be associated with other physical mechanism formations, such as disturbed electric fields. Resende et al., (2020) and Resende et al., (2021) detected anomalous Es layers over the Brazilian sector
dip ∼18º) and São Luís (2.3°S
in which the disturbed electric fields during magnetic storms modified the Es layer structure in these regions
the electric field due to the disturbance dynamo effect (DDEF) caused the Es layer intensification over Boa Vista
a transition station from equatorial to low latitude
causing instabilities during the magnetic storms
Their work used the Hainan COherent Scatter Phased Array Radar (HCOPAR) and frequency parameters of the Es layer driven by Digisonde
Their results suggested that these irregularities occurred due to the Kelvin-Helmholtz instability (KHI) during the daytime
gradient drift instability in the low photoionization background creates unstable Es layers during the nighttime
this work analyses the physical mechanism of these atypical Es layer formations on quiet and disturbed days
providing novel insights about their open questions on this subject
we analyzed a set of days around 5 magnetic storms at a low latitude station
We performed an in-depth analysis of Es layer types and frequency parameters using Digisonde data
we investigated the hiss waves inside the plasmasphere to discard the particle precipitation mechanism in the Es layer development
we include a study about the turbulence in the winds and the gravity wave occurrences
this analysis allowed us to discuss the physical phenomena
which is not much addressed in the literature
We used the data obtained from the Digisonde over CXP to analyze the Es layer behavior. Digisonde is a high-frequency radar that transmits waves from 1 to 30 MHz with a frequency step on 0.05 MHz for CXP and 10 or 15 min of time resolution (Reinisch et al., 2004)
which refers to the frequency point in the upper ionospheric layer where the Es layer blocks the transmitted electromagnetic signal
We also used the ftEs (top frequency) characterized by the maximum frequency that the Es layer reached
We concentrate only on the Van Allen Probes’ data when the satellites are at the perigee
We chose 5 events where the atypical and spreading Es layer were identified over CXP between 2016 and 2018. These events occurred around the geomagnetic storm periods but not necessarily on disturbed days. Figure 1 shows the Disturbance storm time (Dst) variation for the following periods analyzed in this work: (a) March 05–10
Except for the event on May 2018 (panel e)
caused by high-solar wind speed stream (HSS)
the other events were caused by coronal mass ejection (CME)
The Dst index for the events (A) March 05–10
It is well-known that during magnetic storms, disturbed electric fields can influence the ionosphere through the Prompt Penetration Electric Field (PPEF) (Forbes et al., 1995) or by the Disturbance Dynamo Electric Field (DDEF) (Blanc and Richmond, 1980). However, as shown by Resende et al., (2021)
these disturbed electric fields are not capable of causing some influence in the Es layer over CXP
we only want to show that the days of the atypical Es layer presence are around the magnetic storm
occurring on both quiet and disturbed days
we do not present other interplanetary medium parameters
Table 1 shows the day of geomagnetic storm onset
the level of the magnetic storm represented by the minimum value reached by the Dst index
the day of the atypical Es layer occurrence
and the condition of the period (quiet or disturbed)
The Dst threshold used to classify whether the period is quiet or disturbed is −30 nT
the days with Dst lower than −30 nT are assumed to be disturbed in this study
it is possible to clearly see that the Es layer spreading also occurred in quiet periods
the atypical Es layer appears during the recovery magnetic storm phase
which is intriguing since the other Es layer physical formation mechanics also acted in this period
List of the characteristics of selected events from 2016 to 2018 used in this analysis over CXP
the hour of their occurrence and the condition of the period
The significant modifications in the Es layer electron density distribution occurred in the periods shown in Table 1. Figure 2 shows some ionograms for (a) March 05
The fbEs and the ftEs are shown in vertical black lines
We observe a spread Es layer (red and blue arrows) in all ionograms
The main characteristic here is the low values of the fbEs
which means that the Es layer did not block the F region significantly
Ionograms at CXP (A) from 2030 UT to 2050 UT on 05 March
Another important point is that these events occurred in periods considered quiet times, although March 08 and 09, 2016, are in the recovery magnetic storm phase. In fact, this spread Es layer can be attributed to the Esa (auroral) layer during the recovery magnetic storm phase. As discussed by Da Silva et al., (2022) and Moro et al., (2022)
the particle precipitation mechanism can develop the Esa layer over the Brazilian sector due to the SAMA presence
The Esa layer signatures are expected during the recovery magnetic storm phase over Santa Maria and Cachoeira Paulista
which is discussed in the following section
The same spreading Es layer behavior occurred in the other events. Figure 3 presents some selected ionograms on (a) 15 October 2016
the fbEs also have low values (fbEs ≤ 3 MHz)
The Ess presence is also observed over CXP (red arrow)
Some selected ionograms at CXP for (A) 1940 UT
The other case in which the Es layer over CXP suffered a significant modification was on 30 October 2016. Figure 4 shows the ionogram sequences of these Es layers over CXP between 0330 UT and 0610 UT intervals
We notice that the Ess is present between 0430 UT and 0450 UT
the ftEs reached values around 7 MHz at 0410 UT
it is plausible that competition is occurring between the Es layer formation mechanisms
The following section shows the particle precipitation’s role in these events
Ionograms at CXP from 0330 UT to 06100 UT for each 20 min on 30 October 2016
The reason that intrigues us about these events is that the spread Es layer has two different characteristics to the auroral trace
such as: (1) the spread occurrence during quiet periods (Dst larger than −30 nT) and (2) the inclination of the trace in some cases
one important step of this work is to discard the particle precipitation mechanism
we examined the AE index and particle dynamics in the inner radiation belt
the AE is following the same pattern with low values
between 2100 UT and 2300 UT upper-(A) and between 0300 UT and 0500 UT bottom-(B) on 09 March 2016
the low PSD of the hiss waves during these quiet periods (<10−7 nT2/Hz) may not be efficient in causing the low-energy electron precipitation (from 0.5 keV to tens of keV) over the SAMA region
The other cases also presented low values in PSD of the hiss waves (≤10−7 nT2/Hz) (not shown here)
Power spectral density of the magnetic field from EMFISIS instrument onboard Van Allen Probes on March 05
The exception occurred on 30 October 2016, in which it is possible to observe that the hiss wave PSD (∼10−4 nT2/Hz) (Figure 7) is similar to the results discussed by Da Silva et al., (2022)
This value is enough to allow low-energy electron precipitation (from 0.5 keV to tens of keV) caused by hiss waves over the SAMA region
the AE reached values higher than 500 nT
we intend to show that the plasmaspheric hiss waves inside the inner radiation belt reached significant values
and the particle precipitation in the SAMA region can occur in this event
Power spectral density of the magnetic field from EMFISIS instrument onboard Van Allen Probe (A) and (B) on 30 October 2016
we proposed here that the spreading Es layer can occur due to other physical mechanisms than particle precipitation due to the SAMA in most cases
Evidence of low values of the power spectral density of the hiss waves and AE index confirms this statement
we notice the gravity wave presence (Ess occurrence)
we believe that there are competing physics mechanisms in the Es layer formation in this event
the authors mentioned that this instability depends on the strong electric field
the GDI is responsible for the equatorial Es layer (Esq) in stations near the magnetic equator
we believe that the most probable mechanism that acted in the atypical Es layer is the KHI
The first evidence of the instabilities in the ionospheric plasma is the low values of the fbEs, meaning that the upper region above the Es layer has not been blocked. Table 2 shows the difference between the ftEs and fbEs (ftEs-fbEs) during the spreading Es layer occurrence
We present the maximum and minimum differences within the period studied
TABLE 2. Maximum and minimum differences of the ftEs and fbEs parameters of the period shown in Table 1
the differences between the frequency parameters show that the winds have a secondary role in the Es layer development in most cases
The low values of the ftEs-fbEs mean that the upper region is blocked
the high values of these differences mean that the Es layers have not blocked the upper layer
the wind shear that is the main mechanism to form denser layers could be stronger in such hours
The Es layer can be also formed by other mechanisms such as instabilities
the Es layers formed by these other mechanisms do not absorb the digosonde signal
as those denser layers formed by wind shear
This is an indication that irregularities can be present
The minimum values of the ftEs-fbEs observed in our events analyzed here were higher than 1
our results showed an indication that the unstable Es layer in the ionograms profile over CXP can be due to the instabilities since the particle precipitation seems to have influenced only the event on 30 October 2018
Figure 8 shows the previous analysis results using the SKiYMET data for the zonal (right) and meridional (left) wind components on March 05–06
which is the typical altitude of the Es layer occurrence
We also compared the results to the −5/3 Kolmogorov spectrum
The wind speed sampling step is 1 h due to the limitations of the technique and equipment used to obtain the data
We interpolated the values using a cubic spline to 1 min to
Slightly smooth the output due to the signal characteristics
The Fourier power spectral densities of the SKiYMET data for the meridional (upper) and zonal (below) components on March 05–06
The −5/3 Kolmogorov spectrum given in the orange line in these graphs
Although this procedure can change the spectrum in higher frequencies
we analyzed only the frequencies up to 10(−3.5) Hz
This region corresponds to periods of roughly 1 h
the interpolation used in this work does not significantly modify the spectrum in the region we are interested in
The wind components spectra demonstrate an unstable behavior for the frequencies between 10−5 and 10−4 on March 05–06, 2016, as seen in Figure 8
Notice that this result was found close to the −5/3 Kolmogorov value
This fact means that the wind is turbulent at this height during this period
in the specific case of October 29–30
the components of the winds are not oscillating
and the power spectral density is not so close to the −5/3 Kolmogorov value
This analysis provides clear evidence that the spreading Es layer over a low latitude station can occur due to the instabilities. The most probable is the KHI, which is driven by shear flow and is common in the atmosphere (Ecklund et al., 1981; Chen et al., 2020). Using simulations, Wu et al., (2022) analyzed the KHI in the middle and low Es layers
The simulations presented multiple striation structures in the Es layer
The authors found that the polarization electric field is induced in the horizontal structure of the sporadic E (Es) layer
and it is an initial condition to grow up the KHI or GDI
Liu et al., (2022) analyze the Es layer behavior using the Digisonde data applying a technique called frequency domain interferometry (FDI) over Wuhan
The FDI allowed them to observe the inhomogeneous Es layer occurrence in such station
The complex structure of the Es layer found by the authors can be associated with instability or gravity wave modulation
One plausible explanation is the KHI presence in the Es layer formation that is caused by the strong shear of the neutral background wind
The OH images showing the gravity waves presence at 2315 UT on 06 May 2018 (A)
and the Ess layer in ionograms (B) in the nighttime period on 06 May 2018
The Ess is associated with the gravity wave mechanism, and it is characterized by a trace that grows continuously in frequency and emerges from another type of Es trace, as shown in red arrows. This specific Es layer type is not common in the Brazilian sector, as shown in Conceição-Santos et al., (2019) and Moro et al., (2022). We notice that the Ess layer was observed in some hours for all events mentioned in Table 1
there is a possibility that the gravity waves may have a precursor to the growth of instability
is not necessarily due to the particle precipitation due to the SAMA presence
further research is necessary to affirm what is the exact instability that acts on the Es layer formation
We study the atypical and spreading Es layer over CXP in days before
and after the magnetic storms from 2016 to 2018
and meteor radar to understand the dynamic formation processes of these inhomogeneous Es layers
The significant modifications in the Es layer electron density distribution were observed in ionograms on days before and after the magnetic storm
The main characteristic is the low values of the fbEs
which means that the Es layer does not block the F region significantly
the high difference between the ftEs and fbEs (ftEs-fbEs) during the spreading Es layer occurrence indicated that the irregularities could be present
The inhomogeneous Es layer is associated with the Esa layer over CXP due to SAMA
we also observe that the spreading Es layers occurred in days before the magnetic storms or quiet times
We examined the AE index and particle dynamics in the inner radiation belt to discard the particle precipitation mechanism
Our results showed a low power spectral density of the hiss waves in these events (<10−7 nT2/Hz)
inefficiently causing electron precipitation over the SAMA region
the spreading Es layer occurred in hours when AE was higher than 500 nT
the power spectral density of the hiss waves was ∼10−4 nT2/Hz
similar to the previous studies about the Esa layer formation
this value is enough to cause low-energy electron precipitation (from 0.5 keV to tens of keV) by hiss waves over the SAMA region
One of the possibilities of these spreading Es layer occurrences is the instability formation that can affect the wind shear
the Es layer may be formed initially by wind shear
and the environment becomes unstable due to the electric field or gravity waves
creating inhomogeneous layers in ionograms
We used the SKiYMET data for zonal and meridional winds to analyze if the winds were unstable
The temporal resolution of these wind data is 1 h
a linear interpolation was performed every minute to visualize whether the wind could have turbulence
The analysis is not so impaired as we only use measurements between 80 and 100 km
we compute energy spectrum E(k) to verify the turbulence in the winds
we analyzed whether the power spectral densities are close to the −5/3 Kolmogorov spectrum
the wind components spectra were close to the −5/3 Kolmogorov value
This fact means that the wind is turbulent
the wind energy spectrum components were not oscillating
The spreading Es layer observed in our data has an inclined trace in some hours
This Es layer type is associated with the gravity wave mechanism
Several authors mentioned that gravity waves could trigger the instabilities besides the winds
The OH emission in airglow images shows a gravity wave propagation on May 06 and 07
we observe the Ess layer presence in ionograms
the presence of gravity waves may have been a trigger for the instability occurrence
is not necessarily formed by the particle precipitation due to the SAMA
influencing the Es layer development and contributing significantly to our understanding of the different mechanism actions in the atypical Es layer
further research is necessary to conclude precisely what instability caused these inhomogeneous Es layers over CXP

INB President Carlos Freire Moreira said the development was very important for the country
adding: "This undertaking should be a source of pride
since the isotopic enrichment of uranium is a state-of-the-art technology and 100% national
developed by the Brazilian Navy in partnership with the Institute of Energy and Nuclear Research."
Amazul CEO Newton Costa said the company had been preparing for two years to start working on the project which he said would guarantee "the country's energy security with clean energy
with positive impacts in tackling climate change"
The two men signed the contract during a ceremony to celebrate the 20th anniversary of the creation of INB's Isotopic Enrichment Technical Board
INB's fuel fabrication plant (Fábrica de Combustível Nuclear
has a capacity of 160 tonnes per year pellet production and 280 tonnes per year fuel assembly production
which generate about 3% of its electricity
Amazul describes itself as incorporated in 2013 with "the objective of absorbing
transferring and maintaining activities sensitive to the activities of the Navy Nuclear Program
the Submarine Development Program and the Brazilian Nuclear Program" and says its commitment is to "use nuclear technology to save lives
guarantee energy security with clearn energy and defend the country's sovereignty"
ASHLAND — Police say a Framingham man who was among four arrested Wednesday in connection with a pickup stolen from Worcester faces additional charges involving an armed home invasion earlier that day in Ashland.
21, and a teenage boy were armed with shotguns when they forced their way into a Buckley Avenue home early Wednesday morning and violently robbed a couple in their 70s
“This was a good multi-jurisdictional investigation,” said Alfano
“We all worked together to make this happen.”
The home invasion occurred about 2 a.m. Wednesday
the teen and an undetermined number of others who have not been identified forced their way into the home
The husband tried to fight the invaders off
but one of those armed with a shotgun hit the man in the head with the butt of the gun
Police do not know if the victims were targeted
The only item taken was a single electronic device
Police have not found the item and declined to specify what it is
we though this wasn’t a random incident,” said Alfano
“We’ve developed some information that indicates this may have been by chance
that they may have been driving around and just chose this house.”
tracked a scent through some neighboring properties to a location where police found shotgun shells on the ground
A neighbor who had a security camera caught the group of people jumping into a light-colored minivan and driving off
Framingham police conducting a stolen car investigation found the minivan parked on Staples Drive
A Framingham police officer who was following the minivan as it was being towed saw a Ford F150 parked in the Motel 6 parking lot on Rte
and knew it matched the vehicle Framingham police were looking for
ammunition and a handgun that turned out to be a pellet gun
He admitted to his role in the home invasion
The investigation led police to a similar incident in Wellesley that may be connected
The investigation led them to the Framingham teen linked to the Ashland crime
Massachusetts State Police and Wellesley police all went to a Gordon Street residence in Framingham to arrest the teen
jumping from a window into the awaiting arms of an Ashland police detective
Police charged the teen with assault and battery with a dangerous weapon
assault and battery on a person older than 60
The teen also had four warrants for his arrest — three from Framingham and one from Wellesley
“There are still some people we’re looking for
but the ones who possessed the guns and committed the assaults are in custody,” said Alfano
“This is still an active investigation.”
Resende was arraigned Thursday in Framingham District Court and ordered held on $25,000 bail
The teen is being held at a juvenile detention facility until he is arraigned next week in Framingham Juvenile Court
Federal Ice and Custom Enforcement authorities have filed detainers against both Resende and the teen because they are undocumented immigrants
Alfano went to Buckley Avenue and went door-to-door to speak to residents to assure them they were safe

a revolutionary new Volkswagen factory opens in Resende
The million-square-meter Resende factory did not have an ordinary assembly line staffed by Volkswagen workers: In fact
the only people on Volkswagen’s payroll were the quality-control supervisors
Independent subcontractors were responsible for putting together every part of the trucks and buses that the factory produced
which Volkswagen called the “modular consortium,” reduced the company’s labor costs considerably by making them someone else’s problem: The company simply purchased its labor from the lowest bidder
Volkswagen hoped to export this new system to all of its factories in developing countries
eight different subcontractors operated their own mini-assembly shops along the main line—MWM/Cummins built and installed the transmissions and engines
while Ford Motor Company supplied the cabs—and each of those companies was responsible for installing and inspecting its own components
Any quality problems in the finished product were blamed on—and charged to—the subcontractor responsible
The system was an enormously profitable one for Volkswagen
The company was able to negotiate very low rates from its subcontractors for parts and labor
so it saved money on every truck and bus that passed through the Resende plant and could pass those savings along to its customers
competitors who did not use a subcontractor system had difficulty matching Volkswagen’s low prices
The Resende facility may have been Volkswagen’s “Dream Factory,” as some reporters called it
The mastermind behind the modular consortium idea was VW’s head of purchasing
who had defected from GM three years before

that was remarkably similar to the one VW ended up building at Resende

The district attorney’s office identified Cepeda Williams as Resende’s “female companion” and Nehemiah
Prosecutors in court said Resende and Cepeda Williams had an on-and-off relationship for 13 years, and Resende had helped raise Nehemiah since he was 2, The Boston Globe reported
A girl who identified Resende as her stepfather made the 911 call to police early Tuesday morning and told them that he had killed her brother

has officially launched the second work shift at Nissan's Resende Industrial Complex
Silva welcomed the 600 newly hired employees
part of a new work shift added to absorb an increase in the local demand for the Nissan Kicks
Nissan has assembled Kicks since April at its wholly owned plant in the Southern Rio de Janeiro State
"This is a major milestone for Nissan," said Silva
"Local production of the Kicks demonstrates the company's healthy growth
We are strengthening our commitment to the country with investments and the creation of hundreds of jobs."
Production of the Nissan Kicks at the Resende Industrial Complex in Brazil follows an investment of R$ 750 million ($192 million)
The new employees were added to the production process gradually
after being trained and prepared following Nissan's global quality standards
"Nissan has world class manufacturing standards in Brazil with a focus on product quality
sustainability and efficiency," said Silva
a comprehensive training program is pivotal so that employees may perform their activities with autonomy
the new employees underwent a four-stage training course
a program specifically developed in collaboration between Nissan and SENAI
a National Service for Industrial Training
Those who passed the skills assessment tests after the program continued to Nissan's recruiting process
Nissan's Resende Industrial Complex has now a workforce of 2,400 employees divided in two shifts
as well as the modern 1-liter 3-cylinder 12V and 1.6-liter 4-cylinder 16V powertrains

and how a complex process can lead to a simple object
It goes without saying that one of the many reasons book design is so popular amongst designers is due to its versatility
It’s a specialty that the Porto-based graphic designer Ana Resende knows well
having executed a myriad of book design projects ranging from books on film
“making books sounded like a synthesis of what I enjoy the most.” First off
Ana can be working with an artist on a compendium of their work
she’s studying the details of cartography mapping a city she only knew by name previously
film and architecture; two mediums she knew much about long before her interest in graphic design
“it’s all about creating certain visual narratives by using not only words and images but alternative means such as rhythm
book design bares a similarity to architecture in its crafting of a physical experience
“You have to ‘build’ an object that has shape
Ana first graduated with a degree in architecture which led her to work on a research project on the subject combined with film
her first introduction to the creation of printed matter
She liked it so much she decided to undertake further studies
this time in graphic design and editorial projects – an outlet which largely resembles Ana’s practice to this day but with an emphasis on sophisticated spatial awareness; a product of her previous training in architecture
She describes her gravitation toward graphic design as “not an obvious and premeditated choice
but rather the result of a journey led by experimentation
Possible Anatomies: Ana Resende in collaboration with Filipe Paixão and Corpo Atelier (Copyright © Corpo Atelier
Enjoying each and every project for the new challenges it brings
Ana attacks her briefs with a consistent methodology or way of thinking shaped also by her architecture education
The physical output tends to vary depending on the process
“I believe I don’t have a strong sense of authorship (at least not premeditatedly)” she says
her work is a result of multiple inputs which enriches both the creative journey and the final piece in turn
you raise the bar and always learn something along the way.”
which exemplify Ana’s evolving creative philosophy
Possible Anatomies – a collaboration with fellow Portuguese designer Filipe Paixão and architecture studio Corpo Atelier – details a catalogue of the latter’s practice
Ana explains the challenges with this brief: “For a long time
they wanted to catalogue their practice which is profoundly based in the production not only of buildings but also of physical objects such as drawings and models
they knew by doing so (making a mere catalogue) the very essence of its work would not be properly conveyed in print.” In order to showcase the physicality of Corpo Atelier’s practice
“a performative and mental process of discovery”
Despite working intimately on this makeshift catalogue
Ana and Filipe only met once due to the pandemic
as Ana finds it integral in getting to know one’s ideas
expectations and feelings with this kind of highly conceptual yet technical work
the designers landed on a way to communicate Corpo Atelier’s message while respecting their respective perspectives at the same time
The end result is a book inside a plaster model
a book presented which also acts as question mark
Corpo Atelier adds: “By making it unavailable
with no correspondence to the physical reality of the future reader
the sculpture – here representing both container and content – must be destroyed
Its irreparable loss is required for the book to be discovered
An unavoidable consequence as both objects cannot coexist as integral realities.”
Ana touches on the limited run of books designed by Unbabel
a Portuguese startup developing an AI-powered human translation platform combining Neural Machine Translation with machine learning an crowdsourced model
and acts as a starting point to reflect on language
Ana only has one single copy as the limited distribution halted with the pandemic
the designer values the project for its content
printing techniques and the fact that its purpose was compromised straight after it was completed
The project saw Ana and collaborator João Novais design the first issue of a magazine dedicated to literature
visual art and social commentary; offering up an idea of how language evolves alongside society
Compiles of three texts including a non-fiction essay and two short stories
the publication explores the dialogue between humans and nature
how emails can be seen as emotional connections in the digital age
and the evolution of the first extraterrestrial language
the designers considered how to reproduce the experience of an endless space within the limitation of a book
allowing the text to flow from one page to another in a legible way
they also wanted the illustrations to appear continuous
“It had to express complex ideas with simple forms and limited means,” asserts Ana
the collaborators opted to use offset LedUV printing on black paper as an opportunity to test the limits of the printing method; using only four tools – black
pink and brightness (varnish) – to add to the puzzle
“A complex process to build a simple object,” the beautiful outcome is aesthetically considered to match its rigorous conceptual process
And as long as there are new avenues of intrigue for Ana to interrogate
the future of her creative practice remains intact
“The day I know what I will be doing,” she finally goes on to say

BROCKTON — A 38-year-old Brockton man was arraigned in Brockton District Court Tuesday afternoon on charges he murdered his 14-year-old stepson and seriously injured the boy's mother early Tuesday morning
Justelino Resende was charged with one count of murder
two counts of assault and attempt to murder
and one count of possession of an unlicensed firearm and FID card
according to Plymouth County Assistant District Attorney Sharon Thibeault
Resende is the longtime "on and off boyfriend" of the injured victim Felicia Cepeda Williams
Resende and Williams had been together for 13 years and they cared for Williams' three kids from a previous relationship
as well as three other children whom the pair had together
Resende had helped raise the teenager he allegedly killed since he was 2 years old

She reported Resende shot at least two rounds in her direction
one of which investigators located in the wall near where she was standing
and then the defendant went to seek out Williams
Williams was not originally in the bedroom the pair shared
so the defendant then sought out Williams in the bedroom she sometimes slept in with her children
Williams was in bed with one of her children
and the 14-year-old was sleeping in the closet
which he was frequently known to do," Thibeault said
How violent is Brockton? We compared it to 8 other cities to get the real answer.

but she could not understand what he was saying," she said

I killed Felicia," Resende allegedly told his mother
she asked him where he put the gun and he said he didn't know
Police located Resende at his mother's house after putting a call out for his vehicle
Officers placed Resende in the back of a police cruiser and read him his rights

Resende is due back in court April 27 for a probable cause hearing
According to District Attorney Timothy Cruz who was also present at the arraignment
the couple had previously complained about each other but had never gone through with filing restraining orders
and Resende had also served 18 months in prison for a previous gun charge in 2017
and it is good Resende is being held accountable for his actions," Cruz said
"There is a 14 year old who is dead who should've been in school today
We are left with 'why?,' why did the defendant do this," he continued
"We hope to get justice for him and for this family who has suffered a tragedy today."
Cruz was not aware of Williams' medical status
but added that she had undergone a few surgeries and was still in the hospital
This is the second homicide in Brockton this year, following the Dollar Tree shooting on Jan
Superintendent of Brockton Public Schools Mike Thomas said in a written statement Tuesday morning that the 14-year-old victim was a student at the Brockton Therapeutic Day School who "tragically died at his home last night."

"Our hearts go out to the student's family and loved ones as they process this unthinkable loss," Thomas said

"An address was developed on this date and Resende was taken into custody by deputy U.S
marshals and local task force officers assigned to the Fort Lauderdale United States Marshals Service Regional Task Force," Procopio said
Resende was charged as a fugitive from justice in Florida and awaits rendition on the local charges
Resende is facing numerous charges related to a shooting on Aug
The shooting occurred outside 24-26 Wilmington St.
a street on the city’s north side that was also the location of shots fired last June
the city’s electronic gunfire detection system
Officers found at least five shell casings in the driveway of the home
They didn’t locate any victims at the scene
but they did find a blood trail on the ground leading into one of the homes
showed up at Good Samaritan Medical Center with gunshot wounds to her ankles from the incident on Wilmington Street
The injuries were described by police as as not life-threatening
police filed several charges against Resende
including assault and battery with a dangerous weapon
two counts of illegal possession of ammunition
discharging a firearm within 500 feet of a building
illegal possession of a large-capacity feeding device
possession with intent to distribute a Class D substance and domestic violence assault and battery
He was then added to the state police Most Wanted List on Sept
police said the firearm from the shooting had not been located and Resende was to be considered "armed and dangerous."
"Further investigation led to the recovery of a sizable quantity of illegal narcotics resulting in additional charges of trafficking in more than 10 grams of fentanyl," police said
Resende is known to police and has a lengthy criminal history
He was arrested in April 2015 and charged with drunken driving after police said he drove through a stop sign and struck two cars
He was also charged in April 2014 with possession with intent to distribute cocaine and conspiracy to violate drug laws
He has faced other charges dating back to when he was 17 years old
It wasn't immediately clear when Resende would return to Massachusetts to face arraignment
thinking of architecture as a choreography through space
the architects have developed the whole project as an investigation on sensory spatial perception
with a sequence of closed and open areas towards the sky, allowing visitors to experience an ever-changing environment

the plot featured a pre-existing building, whose structure was preserved and became a guideline for the new opaque facade designed by entre terras and pablo resende
what looks as rigid and geometric from the outside
becomes fluid and flexible when entering the building
the interior is organized as a series of rooms of different shapes
with nothing but the sky forming the ceiling in some areas
the space in between these rooms forms a maze-like structure
with an intimate circulation that leads to the dressing rooms
the surfaces of the project are just the result of adding or unveiling layers of materials
the rough texture of the walls appears as a reinterpretation of ordinary landscapes and cityscapes
while the sandstone used is a reminder of the beaches that ‘haight clothing’ originates from
the whole stone formation is characterized by a spontaneous accumulation of sand layers deposited through time
the project is essentially a handmade process of sculpting
making all the natural features evident within the space
