The 49 megawatts the farm is projected to produce would be enough to power more than 10,000 homes
the company hosted a public engagement session at the Royal Canadian Legion in Fredericton Junction
a few people made the trip to learn more about the project
dubbed the White Spruce Wind Energy Project
“It would be connected to the New Brunswick power transmission grid,”
Jason Parisé said the power generated would be fed into the NB Power grid and likely utilized “wherever there’s load nearby
so good transfer towards Fredericton Junction

“It will replace some of the existing fossil fuel sources on the grid here.”
The cost of the project, being done in partnership with Woodstock First Nation, and Nikutik Limited Partnership, and the Soverign Wealth Fund, which was founded by the North Shore Mi’kmaq Tribal Council, is expected to be in the $150-200 million range and construction could take up to 18 months, all on Crown land, 11-15 kilometres south of Fredericton Junction.
The group is hoping to start construction by June 2026.
The public meeting Thursday was part of the steps necessary to have the project formally approved by the province’s Department of Environment.
Those in attendance were mostly hearing about it for the first time.
Debbie Gillett, from Tracy, has lived in the area for 55 years. She said she was there to learn more about the windmills, and that she sees benefits and drawbacks, such as how it could change the scenery at their family camp.
“I think this is probably a good thing. I’m still kind of learning and processing all the things that they said,” Gillet said.
Jason McLaughlin has a house and camp roughly six kilometres from the site. He attended the session with his father, Bob McLaughlan, who’s lived in the area at Upper Tracy all 68 years of his life.
Jason said his biggest concern was not necessarily the noise from construction, but the low frequency sound from the turbines once they’re up and running.
“(I’m) learning about it as I go,” Jason McLaughlin said. “I just heard about this.”
When asked about the noise factor, Parisé said that’s a common concern in more populated areas, but as there no residential properties near the site, any noise heard from afar would be “negligible.”
Parisé said the purpose of these open house sessions is to work with the community and see if there are other special interests in the area, or camps nearby, in case they need to make adjustments to the project.
“It’s really about getting feedback, helping to integrate it into the project design.”

Toronto’s grab-and-go lifestyle is often synonymous with downtown living
some of the best food is on the city’s outskirts
That’s why we are looking at the best places to grab a sandwich in Toronto’s Junction neighbourhood.
When the Pig Came Home (384 Keele St)
A blink-and-you’ll-miss-it delicatessen (and likely one of the best in the city)
When The Pig Came Home is an institution that has been nestled in the Junction for over a decade.
Specializing in working directly with Ontario farmers
This leads us to When the Pig Came Home’s premiere sando — their Reuben on rye.
garnished with sauerkraut and provolone cheese
is the physical embodiment of ‘less is more’ and is one of Toronto’s best sandwiches.
These Michelin-recognized experts have perfected bringing Nashville-style heat to Toronto
Just on the corner of Keel and Dundas in the Junction
these masters of all things fried have carved out their own poultry empire — as they are the only place to get a high-quality fried chicken sandwich in the area.
Their ‘OG’ sandwich is where the magic happens
complete with Nashville-style fried chicken (we recommend medium
pickles and ‘Chica’s Sauce.’
this is the closest thing to southern hospitality in the great white north.
Modeled in the stylings of a Europen corner store — complete with wine and beer to-go — this locale specializes in Italian fare by serving delicious sandwiches on focaccia bread.
The stand-out sandwich for this Junction location is The Giovanna
This delicious picnic-ready snack features hot soppressata
and arugula and demands to be eaten with an espresso or a glass of wine (or two).
UB (Unemployable Baker) Social & General Store (3015 Dundas St W)
coffee and sandwiches the neighbourhood offers.
While visitors will likely be spoiled for choice
the best UB Social & General Store fare on display is the sandwiches on freshly baked croissants or ciabatta
that Noctua’s Breakfast Brioche Bun pretty much is
Filled with all of the base ingredients you’d yearn for in a breakfast sandwich—farm-fresh eggs
and bacon (optional)—this freshly baked miracle tastes as good as it looks.

“How is it this wasn’t blasted to everyone
and how is it we don’t know about it until there is an arrest?”
was arrested last Tuesday after allegedly approaching several children in the city’s west end
Investigators say the incidents occurred between Feb
Petrini was charged with 10 counts of failing to comply with a long-term supervision order and two counts of assault
Petrini had also been previously convicted of kidnapping and repeatedly sexually assaulting a nine-year-old boy at knifepoint in Brampton
He was sentenced to 10 years in prison in 2010 for the 2008 attack and was released in 2018 with a 10-year long-term supervision order
Concerned about Petrini’s past and the current allegations
the parent council at Keele Street Public School issued a statement
“We are gravely concerned about the possibility of his imminent release and the ongoing danger he poses to children.”
A letter addressed to Parkdale-High Park City Councillor Gord Perks
MP Arif Virani and Ontario Premier Doug Ford from the parent council advised them to take action
“We urge you to take immediate and decisive action to ensure Mr
Petrini is not released back into the community … we cannot afford to take risks when it comes to the safety of our children,” the letter reads in part

Andrew Parashis (right) and Andrew Cowe flip houses for a living
Their latest project was a heavily water-damaged Junction semi that they flipped for double the purchase price
They bought the heavily water-damaged home for $950,000 and sold it for over $1.8 million
Andrew Parashis grew up working construction in Toronto with his dad from the age of 16
commute to job sites where he swept floors and helped as needed 10 to 12 hours a day
His mom talked him into buying a house instead
the first thing they do is buy depreciating items and rich people invest,” his mom
echoing a sentiment from a personal finance book she was reading called “Rich Dad
Poor Dad” by Robert Kiyosaki and Sharon Lechter
They co-invested in a rental property in Hamilton
Parashis has bought and rented or flipped about 150 properties in Hamilton
He hosts a YouTube Channel called Property Hustlers that details his adventures in real estate
Flipping is big business across the Greater Toronto Area
where nearly 30 per cent of existing housing was built in 1960 or before
Re/Max Canada flagged renovations and rebuilds as “one of the most underestimated factors” driving up the value of detached houses
which has shot up 35 per cent from 2019 to 2023
The Star asked Parashis and one of his business partners
to walk us through the nitty gritty of one of their newest flips
a brick semi-detached Victorian on a tree-lined street in the Junction
which they bought for less than a million late last year and sold in June for almost double
They agreed to pull back the curtain on the challenges of flipping in one of Canada’s most expensive real estate markets
how much they really make and the one thing that drives them in this high-stakes industry
old high school friends who reconnected after the pandemic
love finding a property that only needs elbow grease and a few cosmetic upgrades to turn a quick sale
two-bath property near Annette Street and Runnymede Road
Water damage from a leaking roof stained the ceiling
There were holes and cracks in the plaster walls
The original hardwood floors creaked terribly
The owner hoped to avoid a stream of nosy neighbours showing up at an open house to gossip about how far the home had fallen into disrepair
so they asked if their realtor knew of any potential buyers
Parashis and Cowe quickly did the math and stepped up
Semis in the Junction have jumped 23 per cent in value over the past year and 120 per cent in the past decade
The median sale price for semis in the neighbourhood was just over $1.08 million when the flippers purchased the home last November
If Parashis and Cowe could gut and modernize this home on budget
restaurants and High Park — would likely ensure a lucrative sale
The owner agreed to let them apply for building
plumbing and electrical permits with the city before the deal closed
allowing them to hit the ground running on renovations soon after the property changed hands
Parashis and Cowe thought their buyer would be a young family trading up from a smaller house or condo and planned the project accordingly
First they asked questions: what did other 2.5-storey brick semis in the area sell for
bungalows and small homes are disappearing
the Star takes a look at the impact of house flipping on Toronto’s neighbourhoods and housing market
Looking for a Toronto house under $1 million? So are house flippers. Here’s how they’re pushing up prices across the city
An $845,000 loss, forced home sales: Is the era of the pandemic home flipper coming to an end?
“We basically need to always look to not renovate beyond what the area commands,” explains Parashis
you need to be able to show that things were done safely
Nobody wants to move into a million-dollar home that somebody might feel has been hacked together.”
While Parashis often converts basements of his flips into in-law or rental suites
his homework and his realtor’s advice assured him this feature wasn’t a priority on the street
tore down non-structural walls to open up the main level
The primary bedroom got built-in wall-to-wall closets
quartz counters that look like Carrara marble and an island that seats three
“Look at what’s going on around you and don’t get too emotional about it,” Parashis says on choosing finishes and features
“We need to make something that is not going to offend somebody but is also not going to be completely unstimulating to somebody.”
he experimented by installing an open-concept bathroom in the primary bedroom
a design idea he borrowed from a boutique hotel
“We got very mixed reviews,” says Parashis
“I’ll never do it again.”
they reached out to a private lender for a six-month open mortgage
While the interest rate in situations like this is generally high at 10 to 15 per cent
Parashis and Cowe said they’re focused on the potential profit margin and how quickly they can reinvest into the next project
Parashis has been practising something called the “BRRRR method” (pronounced like brrrr
though he’s skipping the rent and refinance stages on this one
Parashis and Cowe relied on five friends to help provide the combined $350,000 in “hard cash” for the renovation plus an extra $85,000 in carrying costs
The funds they raised through friends also covered closing costs
The friends loan the money in exchange for a projected return on their investment
pricing it under what they wanted in a potentially risky but calculated move to attract a larger pool of buyers who capped their search at a max price at $1.5 million
The real estate listing called it a “showstopper” and a “stunning back-to-the-bricks renovation.” It highlighted the renovators’ attention to detail: stair lighting
the revamped Victorian sold for $1.810 million
which is about $800,000 more than the median value of a semi-detached in the neighbourhood
The buyers turned out to not be a young family but a retired couple who wanted a nice space to host their grandchildren
Cowe and their partners split a profit of roughly $300,000
which they divided based on a set percentage they agreed on before the project began
The shares are weighted according to the level of risk they agree to carry and their assigned roles
Cowe gets a larger cut because he acted as the project’s managing partner
success carries a weight; it perpetuates the stereotype of the “greedy investor,” said Parashis
“For the people who do particularly well
there’s always an interesting driving force
It sounds very fortune cookie-like when you say it
but it really does seem more like money is a byproduct of that force.”
it’s the voice of his mom in his head
She died a few years after they started investing together

A man arrested by the Toronto Police Service (TPS) on Tuesday after an investigation into a trio of suspicious incidents involving children in the Junction area was previously convicted of kidnapping and repeatedly sexually assaulting a nine-year-old boy at knifepoint in Brampton
was sentenced to 10 years in prison in 2010 for the 2008 attack
At the time, police said the boy was kidnapped at knifepoint on his way to school in Brampton
managed to get the boy into a nearby home where investigators say the child was repeatedly sexually assaulted over a six-hour period
The boy managed to escape into the woods behind his school and run home
Police said the boy was understandably “traumatized.”
ultimately serving eight years in prison before he was released in 2018 and began living in the Kingston
area under a 10-year long-term supervision order
According to The Kingston Whig-Standard newspaper
Petrini’s presence in the community prompted Kingston Police to issue a rare public safety notice
The Whig Standard also reported that Petrini had more than once violated some of the conditions of his release while living in the city
with the Parole Board of Canada deeming him a “risk to society.”
It’s not clear when Petrini began living in Toronto
CityNews reached out to TPS to ask if the public was informed that he was living in the city but did not hear back before publication
Petrini was arrested on Tuesday after allegedly approaching several children in the city’s west end
was charged with 10 counts of failing to comply with a long-term supervision order and two counts of assault
The friends and family of a 46-year-old Toronto-based jazz musician are remembering the woman as a beautiful and talented individual gone too soon
Julia Cleveland was identified as the female victim fatally struck by a driver who was involved in a two-vehicle crash in the Annette Street and Pacific Avenue area on Monday night
Toronto police said a Hyundai Elantra collided with a Hyundai Tucson
The vehicle was redirected onto the northwest corner
striking Cleveland and her partner as they were out for a walk in the Junction neighbourhood
suffered minor injuries and was transported to hospital
The driver of the Hyundai Tucson was also treated for minor injuries
Tributes poured in following news of the woman’s death
with friends and family members taking to social media to honour Cleveland
described as an accomplished jazz musician and percussionist
“Julia Cleveland was a wonderful person
and kind all rolled into one,” read one post on Facebook
“Unbelievably saddened to hear that you are gone,” another post read
Cleveland was working as a finance manager with the Toronto Musicians Association
Scott Shutt called the incident “tragic” as being hit by the vehicle involved was “unavoidable.”
“Speed looks like it was a factor,” said Shutt
who added the investigation is still ongoing when asked whether charges would be laid
The drivers remained at the scene and are cooperating with the police
Toronto police’s homicide unit is investigating after a woman was found dead in The Junction on Tuesday

inside the residence with trauma to her body
Investigators are working to identify the woman and contact her next-of-kin
No further details were immediately available
Critical care paramedic Christopher Wilkinson arrived at Westfield 30 minutes after Joel Cauchi attacked 16 people
A New South Wales ambulance officer who attempted to save the lives of Bondi Junction stabbing victims on 13 April 2024 says he was “frustrated” after not being able to access injured and potentially dying patients
Six people were stabbed to death by schizophrenic man Joel Cauchi at the Westfield shopping centre
Critical care paramedic Christopher Wilkinson on Wednesday told the inquest into their deaths that he arrived on the scene at 4.03pm that Saturday
Read moreWilkinson travelled to Bondi Junction from Bankstown in a critical care ambulance equipped with blood
plasma and a surgical pack that allowed multiple surgeries on the scene
“We were on scene only a short period of time … when a paramedic came down to us and said they had a baby who needed help,” he said on day three of the coronial inquest
Sign up for the Afternoon Update: Election 2025 email newsletter
The paramedic told the court he provided specialist equipment for the baby
then went back to the triage station he had set up
“I was tapped on the shoulder by a man who was covered in blood,” Wilkinson told the court
He said the man was a doctor who told him that another man who had been brought out of the shopping centre urgently needed care
and “he thought he was going to pass away”
A CareFlight medical team was sent to take care of the patient
Wilkinson and most other paramedics were not given access to the Westfield
security guard Tahir was brought out on a stretcher
Wilkinson was immediately “tied up with trying to treat him”
They conducted surgery but Tahir was declared dead at 4.24pm
“The family can rest assured that we did everything possible to save his life,” the paramedic told the courtroom
A woman in her early 20s with a stab wound in her chest was then brought out
she was able to talk in sentences,” he said
She did not require the need of a medical team and was sent to hospital
Another woman who was stabbed in the upper right part of her back was next
did not have a high heart rate and was transported to hospital
“I was left standing there wondering whether there were any other patients like Mr Tahir to be treated.”
Wilkinson was told there was a “hot zone” established before Tahir was brought outside
But the zone was not officially declared until 4.28pm
He was told the hot zone was put in place after concerns were raised that there could be a second offender at large inside the shopping centre
Wilkinson understood it was an “active situation”
with the hot zone designation preventing paramedics from entering the Westfield
“I was trying to understand why people weren’t coming out or we weren’t allowed in,” he said
“I felt there was quite a long time involved in decision making for either paramedics to go in or paramedics to go out.”
Wilkinson was highly experienced in active armed offender situations, he told the court, including in the case of fugitive Malcolm Naden
He said it took “far too long” for the paramedics at Bondi Junction to be given access to potential patients inside the centre
“Standing around on the outside … and not going in simply because there could be another offender,” he said
He said he was frustrated “thinking that people may well be dying upstairs”

telling you what’s happening and why it matters
He said he would have liked paramedics to have been able to take stretchers inside with a police escort
there is a delay and sometimes that delay costs lives
I think we need to change the way we do things.”
Wilkinson acknowledged that a hot zone was designated with good reason
He told the court the sound of Westfield’s emergency alarm made radio communication and conversation hard on the day
heard a radio message at 4.01pm that intelligence suggested a second armed offender was at the scene
and all crews were to remain in place and not move until advised
he could see an ambulance marshalling and egress area had been set up “extremely well”
The inquest heard a police officer at Bondi Junction had a conversation with a senior ambulance officer who asked whether the scene was a hot zone
The ambulance officer then asked why paramedics were in a hot zone
claimed the senior ambulance officer then allegedly told him: “If any of my paramedics get hurt or stabbed it’s on your head.”
Armitage on Wednesday categorically denied saying or hearing those words
He made the decision to withdraw all NSW ambulance personnel
with a radio message at 4.28pm declaring Westfield a live hot zone
a police review of security CCTV room footage determined there was no second offender
the area would not have been hot,” Armitage said
adding he would probably still have withdrawn paramedics from Westfield given there were no other victims at the scene
Armitage said the hot zone declaration was not downgraded
but should have been after he learned at about 5pm that there was no second offender
“the NSW Ambulance response was all but concluded
The court heard the hot zone declaration made no clinical impact
Armitage said seamless communication between agencies was needed
He said the volume of people still at the scene
including children and an elderly woman who needed attention at the rear of an Apple store
meant non-urgent ambulance care was in place into the early evening
Both witnesses offered condolences to the family members of the victims
A multi-building proposal at 43 Junction Road in Toronto’s Stockyards District has been revised in a resubmitted Official Plan Amendment application. Designed by Core Architects for Diamond Corp
the updated plan greatly reduces proposed employment uses while adjusting the affordable housing terms
The six-tower development would now range from 18 to 35 storeys
designed by Core Architects for Diamond Corp
The 2.6-hectare site at 5 and 43 Junction Road is bordered by Keele Street to the west
the site includes surface parking and commercial uses like an LA Fitness
A medical office located in the northeast corner of the site would be retained as part of the redevelopment
The surrounding neighbourhood features a mix of residential
Looking southeast from Junction Road to the LA Fitness at the current site
In 2021
an initial application proposed six residential towers with nearly 1,888 units and 6,728m² of employment space
The developer revised the proposal in 2023 to include a 6-storey office podium
The latest revision to 43 Junction significantly reduces the amount of employment space
slashing the non-residential Gross Floor Area (GFA) to just 3,095m² of retail use
such as rising office vacancy rates and the lasting impacts of remote work trends.
Previous design by Core Architects for Diamond Corp
The revised plan would also modify the affordable housing obligation
the commitment was that affordable units would be maintained for 99 years
but this has now been reduced to a 25-year term
The developer has attributed this change to the legal and operational complexities of enforcing such a long-term obligation and the site falling outside of any Major Transit Station Areas (MTSA)
The commitment aims to deliver approximately 80 to 100 affordable units
representing 5% of the residential GFA set at Average Market Rent (AMR)
The revised plan proposes 124,834m² of residential GFA with 2,001 residential units
a reduction from the previous plan’s 126,453m² of residential GFA and 2,593 units
It includes approximately 5,185m² of combined indoor and outdoor amenity spaces
Bicycle parking has been increased to 2,231 spaces
Phase 1 would feature 1,017 units across three buildings at 18 storeys (66.50m)
The shorter towers would sit on a shared podium
which would transition from a 7-storey height along Junction Road to a 4-storey streetwall
with a GFA of approximately 58,697m².
Its three-level underground garage would provide 478 car parking spaces and 1,133 bicycle parking spaces
With nine elevators servicing the three buildings
Phase 1 would offer a ratio of one elevator per approximately 113 units
indicating longer than preferable wait times
Phase 2 would house 24-storey (84.50m) and 35-storey (117.50m) towers adjacent to the newly relocated public park spanning 2,380m²
There would be 716 residential units with seven elevators
or approximately one elevator per 102 units
The single-level underground garage in Phase 2 would include 369 car parking spaces and 794 bicycle parking spaces
Phase 3 comprises a single 18-storey tower standing at 63m
This building is significantly scaled back from the previous two-tower proposal to maintain a mid-rise form along Keele Street
With 268 residential units and three elevators
there would be approximately one elevator per 89 units
indicating minimal wait times for residents
The single-level underground garage shared with Phase 2 would offer 202 car parking spaces and 304 bicycle parking spaces
the area is served by the 512 St Clair streetcar and several TTC bus routes
The development is located approximately 900m south of the future St Clair-Old Weston GO station

Reproducibility of Al/AlOx/Al Josephson junctions is a challenge for scaling up superconducting quantum processors
The frequency uncertainty of the transmon qubits arising from the fabrication process is attributed to deviations in the Josephson junction microstructure and electrical properties
we present a solution for this problem using the post-fabrication Josephson junction thermal annealing process
The developed thermal post-exposure method allows not only to increase the junction resistance by 175%
but also to decrease by 60% with a step of 10% in Rn
which opens up new possibilities for tuning the frequency of qubits
The resistance is shown to be strongly temperature dependent
and is weakly dependent on the holding time
The linear dimensions of the electrodes and the sidewalls contribution to the total JJ area also have a significant impact on the final resistance after annealing
a theoretical model of the structure modification in a tunnel barrier with changes in oxygen concentration gradient is proposed
The proposed thermal annealing approach can be used to form stable and reproducible tunnel barriers and scalable frequency trimming for widely used fixed-frequency transmon qubits
we introduce a post-fabrication tuning JJ method for a controlled changing of a normal resistance Rn
We demonstrate wide range of resistance tuning with an increase to 175% and a decrease to 60% for JJ areas of 0.01
We observe a not standard behaviour of the JJ tunnel barrier at temperatures of 200 and 300 °C
Such annealing lead to a decreasing of the normal resistance
We show the resistance depends on a temperature and a holding time
and can decrease to 60% for a small junction area of 0.01 μm2
Our hypothesis is that some temperature exposure lead to reduce a normal resistance by the tunnel barrier thinner
The thin layer contains a smaller TLS density that need to improve the qubit coherence
We also believe our experimental results can helpful to understand the internal mechanisms of the tunnel barrier under thermal exposure
the proposed technique allows to increase and decrease of the JJ normal resistance in a wide range and can be further improved with local JJ tuning techniques
Obtained results open up possibilities for the scalable high coherence quantum circuits
A total of 420 JJs inside 12\(\:\times\:\)12 mm2 area chip tested for each thermal annealing mode
The quality and uniformity of the deposited electrodes were examined using scanning electron microscopy
To investigate the microstructure of Josephson junctions
lamellae were prepared and then examined using the facility of TEM
which is equipped with an X-ray Energy Dispersive Spectroscopy (EDS)
The JJ room temperature resistance was individually measured using an automated probe station
The stylus profiler was used to measure the surface roughness of the bottom JJ electrode
Thermal annealing was performed in a rapid thermal process powerful multi-zone infrared lamp furnace
The substrate temperature was controlled using thermocouples
Annealing was performed in an argon atmosphere with varying temperature and holding time
Typical process of thermal annealing at 400 °C with 10 min heating time
and 60 min cooling time (a); SEM image of the fabricated junction used in this work with diagram of a single JJ (b); oxygen concentration gradient in the tunnel barrier at the Al/AlOx interface before and after thermal annealing (c); dependence of the change in the resistance value on the thermal annealing mode for JJ with area (above each mode indicated the coefficient of variation Rn): 0.010 μm2 (d)
This result was noticed only in one mode of thermal annealing (400 °C and 60 min holding) for all JJ sizes
Before reaching a certain temperature and holding time
the system does not have enough energy for the transition from an amorphous state to a crystalline state
This threshold is reached at 400 °C and holding times in the range of 10–60 min
Dependence of the change in resistance on the thermal annealing mode for JJ with different contributions of the sidewall (junction area – 0.025 µm2) (a); TEM image of the AlOx layer (b); quantitative map of oxygen (atomic percentage) (c); cross-sectional line profile of the oxygen ratio from the marked area (zone I – centre) (d); cross-sectional line profile of oxygen ratio from the marked area (zone II – sidewall) (e)
the thinnest region in the barrier may act as an active region or «hot spot» for tunnelling
Increasing the RMS surface roughness of the electrode may decrease the percentage of the area involved in tunneling
decreasing the effective area increases Rn
Changing the resistance in both directions (increase and decrease) opens up new possibilities for the frequency detuning of superconducting qubits
The developed method of thermal annealing allows not only to increase the junction resistance by 175%
The tuning technique is capable of a step of 10% in Rn as the resistance decreases
LASIQ allows you to point-to-point increase in resistance
Our method allows us to roughly reduce the resistance by raising the frequency value

Please either cite it or delete this reference from the reference list."
To solve the problems of frequency collisions and decoherence of superconducting qubits
we performed a systematic study of Josephson junction thermal annealing technology
we fabricated a significant number of junctions and directly measured the change in their room temperature resistance depending on the thermal annealing mode
We achieved an Al/AlOx/Al junction Rn increase of 175% and a decrease of 60% with a step of 10% in Rn
The increase in JJ resistance is a typical result that can be obtained by crystallizing the amorphous structure of aluminum oxide and changing the bottom electrode morphology
We suppose the resistance reduction connect with an effective thickness decrasing due to the diffusion of atoms in the oxygen concentration gradient
Thermal annealing increases the effective junction area by equalizing the thickness of the tunnel barrier and incorporating the sidewalls into the tunneling process
The results obtained open up new possibilities for frequency tuning of qubits: raise or lower the frequencies of already fabricated qubits across the chip
The proposed method is compatible with technologies of local anneal Josephson junctions
and their combination will allow tuning of the qubit frequencies over a wide range for scalable superconducting processors

The Madison Information Station dates from 1929–30 and is a National Historic Landmark
It began its new life as an information station and bookstore during the summer of 1995
The rustic station contains touch-table exhibits and is staffed by a ranger
Two different trailheads lead to Fairy Falls
which at 200 feet (61 m) high is one of Yellowstone's most spectacular waterfalls
The northern trailhead starts at the end of the Fountain Flat Drive and follows an old road across meadows and near hydrothermal features
The southern trailhead starts at the Fairy Falls parking area and follows an old road along the edge of the Midway Geyser Basin
Also along this trail is the side-hike up to the Grand Prismatic Overlook Trail to a wonderful view of Grand Prismatic Spring and the rest of the Midway Geyser Basin
The Firehole River starts south of Old Faithful
runs through the Upper Geyser Basin northward to join the Gibbon River and form the Madison River
The Madison joins the Jefferson and the Gallatin rivers at Three Forks
The Madison is a blue-ribbon fly-fishing stream with brown and rainbow trout and mountain whitefish
the Firehole River is world-famous among anglers for its pristine beauty and abundant brown
There are a lot of hydrothermal wonders to discover in this region
from small geysers and fumaroles to more well-known mudpots and hot springs
This is also a popular area in the summertime
Terrace Springs is a small thermal area just north of Madison Junction where a short boardwalk leads out to hot springs
Fountain Paint Pot is a popular stop where you can take in all four of the park's major hydrothermal features: fumaroles
Fountain Paint Pot is one of the more famous mudpots in the park
Next to Fountain Paint Pot is the Firehole Lake Drive
This drive leads you past many hydrothermal features
including Great Fountain Geyser and White Dome Geyser
Further to the south is Midway Geyser Basin
home to perhaps the most photographed hot spring: Grand Prismatic Spring
Next to Grand Prismatic Spring is the massive steaming crater of Excelsior Geyser
which back in the late 1800s was still erupting over 300 feet (91 m) into the air
Firehole Canyon Drive follows the Firehole River upstream from Madison Junction to just above Cascades of the Firehole
The drive takes you past 800-foot thick lava flows and to a viewing area of Firehole Falls
Also along the drive is an unstaffed swimming area, which is very popular in the warmest part of the summer season. Learn more about the hazards of swimming and soaking in Yellowstone

Block context plan for the Sterling Master Plan
The earliest proposal for this block was Castlepoint Numa’s 10-storey Museum FLTS
with a subsequent sale made to Marlin Spring
The Sterling Master Plan — being carried out by three different owners — is divided into five further subdivided development blocks
and POPS (Privately-Owned Publicly-accessible Space)
Marlin Spring's initial proposal for Block 3B was a tower rising to 14 storeys from a 5-storey podium
Previous design by Giannone Petricone Associates for Marlin Spring Developments
designed by Giannone Petricone Associates for Marlin Spring Developments
Where the previous Block 3B proposal rose to 51m and comprised 181 residential units
the current submission would soar to 92.74m with 349 units
The residential Gross Floor Area (GFA) would now be 21,097m²
a significant increase from the previous 12,282m²
This would be complemented by 1,206m² of non-residential GFA
which includes retail and commercial spaces at grade
This results in a Floor Space Index (FSI) of 8.53 on the block
The design allocates 718m² for indoor and 525m² for outdoor amenities
the design introduces retail and commercial spaces
The two-storey daycare centre would face the Block 3D POPS to the south and have its own private elevator
while three elevators would serve the residential suites
resulting in approximately one elevator for every 116 units
indicating slightly longer than preferable wait times for residents
Three levels of underground garage would provide 97 parking spaces for residents
plus 47 spaces for the Tower Automotive Building
The proposal also includes 315 long-term and 36 short-term bicycle spaces for residential use
the site is flanked by Dundas West and Lansdowne stations on Bloor Line 2
placing it within the Major Transit Station Areas of both subway stations
The Bloor GO/Union Pearson Express (UPX) station is also within walking distance
There are dedicated bicycle lanes along Bloor Street West
an additional GO station on the Barrie line is planned near Bloor and Lansdowne
potentially to commence service in November
a redevelopment of the existing shopping centre would feature seven buildings ranging from 6 to 38 storeys
that tracks projects from initial application.
The Conservation Officer Service (COS) has attended and confirmed reports of a Grizzly Bear in the Function Junction and Cheakamus area of Whistler
This is the same bear that was on the Western outskirts
but has now moved to the South end of the community
Residents and visitors are asked not to travel to these areas to view the bear
to ensure the bear is not crowded and has the space it needs to feed and perform natural behaviours
The following actions can be taken to reduce the risk of conflict with bears:
carrying bear spray when hiking and biking can help if a situation escalates beyond an encounter
Check around you to ensure there are no other bears
cubs or a food source the bear may be trying to access
If you do find yourself between a bear and cubs or a food source
move calmly and quietly to the free area to create space between yourself
Remaining calm and not making loud noise shows the bear that you are not a threat to them and want to leave the area
Please report any conflicts with grizzly bears to the COS on: 1-877-952-7277.

The former chief of a Delta Junction-area volunteer fire department has been indicted on felony charges related to the alleged theft of some $400,000. The loss of funds forced the Rural Deltana Volunteer Fire Department to suspend operations last year
A Fairbanks grand jury last month indicted 62-year-old Michael Paschall with two counts of first-degree theft and one count of falsifying business records. According to a news release issued last Friday by the state Department of Law
Paschall also is charged with scheming to defraud
evidence tampering and misapplication of property
Rural Deltana board chair Dave Neuberger told KUAC early last year that board members contacted Alaska State Troopers after discovering what he called “accounting discrepancies.”
“Once we discovered this serious breach of trust
we took immediate action to address the situation,” Neuberger said
Paschall had for years served as chief of Rural Deltana
which provides fire protection to areas outside of Delta Junction
And he held the secretary’s seat on its board of directors
But the board fired him in January 2024 and removed him from his seat after an audit showed that $400,000 had been stolen from the department over the preceding seven years
Board treasurer Nelson Grier said board members also discovered that Paschall had for years failed to pay for the department’s insurance policy
“We did not have insurance for a substantial amount of time
Grier said in an interview Tuesday that board members couldn’t get any other insurance company to cover the department
so they shut it down and locked all its equipment in its two fire stations north and east of Delta Junction
the board worked out a deal with the City of Delta to allow Rural Deltana volunteers to train with the city’s volunteers and cover their insurance while responding to a fire
The city also agreed to lease Rural Deltana fire trucks
“So we have kind of teamed with the city,” he said
“The City of Delta has done a very good job in helping our firefighters get under their insurance policy … They’re our volunteer firefighters
but they came under the city umbrella for responses.”
Paschall left Alaska in January 2024 and is now living in North Carolina
he declined to talk much about his indictment
saying only that he’s “cooperating with authorities.”
State investigators say Paschall falsified records to hide the $400,000 theft and that he took the department’s laptop with him when he left the state
A spokesperson for the state Law Department said in an email Thursday that the case was assigned the Alaska Bureau of Investigations and that it was also investigated by the Alaska State Troopers’ Financial Crimes Unit
The case is being prosecuted by the Law Department’s Office of Special Prosecutions
Paschall pleaded not guilty to the charges during a hearing Wednesday at the Rabinowitz Courthouse in Fairbanks
He also asked the court to appoint a public defender to represent him
The court allowed Paschall to remain in North Carolina
But he'll be required to pay a $250,000 unsecured bond if he does not appear at future court proceedings as ordered
The case has been assigned to Judge Patricia Haines

A passenger on board a small aircraft that crashed at the Haines Junction airport has died
the Yukon Coroner’s Service confirmed by press release on June 12.
The release identifies 68-year-old Jean-Jacques Gemme of Amherst
Gemme was one of five passengers plus a pilot on the flight
The notice from the coroner's service doesn’t provide the status of the other four passengers and the pilot.
Haines Junction RCMP went to a report of a plane crash at 1:52 p.m
emergency medical services including air ambulance
airport personnel and the Haines Junction Fire Department all took part in the emergency response
The coroner’s service was notified shortly after 2 p.m
when a death was confirmed at the crash site.
The release notes the Cessna U206 aircraft was flying commercially and returning from a sightseeing flight in the Haines Junction area
Gemme and his partner had been travelling through the western United States and Canada
The pair was en route to Alaska when they stopped in Haines Junction on June 10.
The Transportation Safety Board of Canada and the Yukon Coroner's Service previously confirmed they are investigating a fatal plane crash that took place in Haines Junction on June 10.
A notice issued by the safety board at 7:30 p.m
on June 10 confirmed that it has deployed investigators following the crash of a Cessna aircraft operated by Rocking Star Adventures Ltd.
The coroner’s service continues to investigate alongside the safety board and RCMP and extended condolences to Gemme’s family and the Haines Junction community.

The development of next-generation materials such as hBN and Ga2O3 remains a topic of intense focus owing to their suitability for efficient deep ultraviolet (DUV) emission and power electronic applications
forming a pseudo-vertical pn hBN/Ga2O3 heterojunction device
Rectification ratios > 105 (300 K) and \(\:\sim\)400 (475 K) are observed and are amongst the highest values reported to date for ultra-thin hBN-based pn junctions
The measured current under forward bias is ~2 mA
which we attribute to the shallow Mg acceptor level (60 meV)
device performance remains stable and highly repeatable after a multitude of temperature ramps to 475 K
Capacitance-voltage measurements indicate widening the depletion region under increasing reverse bias voltage and a built-in voltage of 2.34 V is recorded
The hBN p-type characteristic is confirmed by Hall effect
a hole concentration of \(\:7\times\:{10}^{17}\) cm−3 and mobility of 24.8 cm2/Vs is achieved
Mg doped hBN resistance reduces by >108 compared to intrinsic material
Future work shall focus on the optical emission properties of this material system
This naturally leads one to consider the formation of hBN/Ga2O3 heterostructures where the aforementioned challenges can be overcome owing to their complementary material properties
we show that Mg doped hBN (ambient wet-transfer process) on n-type Ga2O3 can lead to the formation of high quality stable pn junction diodes
this is the first report of a pn heterojunction formed between multilayer p-type hBN and n-type Ga2O3
Vacuum base pressure was 7\(\:\:\times\:{10}^{-2}\) Pa prior to growth
The electron carrier concentration is \(\:\sim\)1 \(\:\times\:\) 1018 cm−3 determined by Hall measurement

Morphological and thickness measurements were performed by scanning electron microscopy (SEM)
optical microscopy (OM) and atomic force microscope (AFM)
X-ray photoelectron spectroscopy (XPS) was used to determine B: N stoichiometric ratio
Raman spectra (JadeMat DPL 532 nm laser) was obtained with a 100 mW laser and 20 s integration time
λ = 1.54 Å)) was used to confirm hBN crystallinity
Ultraviolet photoelectron spectroscopy (UPS) was performed using a ULVAC-PHI 5000 Versaprobe II system (He UV light source) with an energy resolution of 0.02 eV (beam diameter 300 μm) to locate Fermi level position
The Mg acceptor level was identified through temperature dependent Hall effect analysis on a reference sample transferred onto sapphire substrate
Capacitance-Voltage (C-V) and Current-Voltage (I-V) analysis is performed by a Solartron 1260 A impedance system and a HP4140B

In Fig. 4d built-in potential (Vbi) and doping concentration (NA) can be determined assuming an abrupt pn+ junction (Eq. 1)
Extrapolation from 1/C2 yields a \(\:{v}_{bi}\) of 2.34 V from the linear gradient
The 1/C2 gradient is non-linear implying a non-uniform doping profile at the pn junction interface
A net NA concentration of 7.0 \(\:\times\:\)1017 cm− 3 has been extracted from the slope of the linear segment when ND is 1.0 \(\:\times\:\)1018 cm− 3 (Ga2O3 doping level)
These findings are in agreement with Hall effect measurements
(ΔEv < ΔEc34)
Band diagram of the p-hBN/n-Ga2O3 junction by Anderson’s method
Pseudo-vertical high performing hBN/Ga2O3 pn junctions have been demonstrated
Rectification ratios > 105 and leakage currents < 0.2 \(\:\mu\:\)A are measured at 300 K and devices continue to operate reliably after high temperature ramping to 475 K
C-V analysis indicates device performance follows classical pn junction behaviour as bias voltage varies
The hBN carrier concentration is \(\:\sim\)7\(\:\times\:\)\(\:{10}^{17}\) cm−3 in reasonable agreement with C-V analysis
UPS analysis suggests FLP effects are present
and the theoretical Vbi is in good agreement with the measured value
We expect further performance gains as hBN doping and growth improves

A powerful storm ripped its way through Carl Junction on Easter Sunday afternoon
leaving a trail of destruction in its wake
With wind gusts clocked as high as 92 miles per hour
prompting the closure of Carl Junction schools today
particularly along Fir Road and other western Jasper County neighborhoods
With emergency first responders working tirelessly
the Carl Junction community also saw volunteers checking in at the CJ Community Center to assist with cleanup efforts
Damage in the area included uprooted trees
broken windows and a lot of debris scattered
A large portion of Carl Junction lost power
with Carl Junction Schools announcing the Monday closure via their Facebook page
urging residents to “be safe Bulldogs” as the community rallied to recover
Rainfall totals in the area reach five inches and more in some spots
beta This is a new service – your feedback will help us to improve it
Major work to improve safety at the Maumbury Cross junction in Dorchester moves to the main crossing areas from Tuesday 11 February
This phase includes installing more signal-controlled pedestrian crossing points
widening and levelling of footways where possible and upgrading existing equipment
which took place just south of the Maumbury Cross junction
Focus will now shift to the main junction area
Four-way temporary traffic will be set up to start after the morning peak commuter/school traffic on 11 February
These signals will be monitored and adjusted to maintain traffic flow as much as possible
The signals will remain in place 24 hours a day during the improvement work
Please allow extra time whenever possible for your journey through the junction
Once the current signalling equipment and pedestrian islands have been removed
alterations will start in the southeast and northwest areas of the junction on Maumbury Road
Edward Road will be closed between Coburg Road and Weymouth Avenue (B3147) from 9am on 11 February for the duration of the works
Pedestrian access will be maintained through the site
but as it is a working area there will be times when a slight diversion is necessary
Cabinet Member for Place Services at Dorset Council said: “Thank you for your co-operation while we carried out our initial works which are scheduled to complete on time
"Our team will endeavour to minimise disruption as they carry out the main junction work
there will be times when traffic is slower so we thank you for your patience
“The completed upgrades will create a safer environment for the thousands of residents
and commuters who rely on this crucial junction daily.”
limited space to pass or wait to cross and only one controlled crossing point can make it a daunting experience
especially for anyone with limited mobility or vision impairments
Full views of approaching vehicles can be difficult
and the current layout means some people have to wait in the middle of the road to cross
The junction can also be particularly challenging during rush hours when commuting to and from work or school by foot
Watch a video of the difficulties faced when using the junction before improvements.
There will be a new layout and an upgrade of the existing signalling equipment
The works are scheduled to complete by May 2025

Spinal cord cross-sectional area (CSA) is a relevant biomarker to assess spinal cord atrophy in neurodegenerative diseases
the considerable inter-subject variability among healthy participants currently limits its usage
Previous studies explored factors contributing to the variability
yet the normalization models required manual intervention and used vertebral levels as a reference
which is an imprecise prediction of the spinal levels
In this study we implemented a method to measure CSA automatically from a spatial reference based on the central nervous system (the pontomedullary junction
we investigated factors to explain variability
and developed normalization strategies on a large cohort (N = 804)
Following automatic spinal cord segmentation
the spinal cord CSA was computed on T1w MRI scans from the UK Biobank database
the CSA was computed at the level of the C2–C3 intervertebral disc
the CSA was computed at 64 mm caudally from the PMJ
this distance corresponding to the average distance between the PMJ and the C2–C3 disc across all participants
The effect of various demographic and anatomical factors was explored
and a stepwise regression found significant predictors; the coefficients of the best fit model were used to normalize CSA
CSA measured at C2–C3 disc and using the PMJ differed significantly (paired t-test
The best normalization model included thalamus
sex and the interaction between brain volume and sex
The coefficient of variation went down for PMJ CSA from 10.09 (without normalization) to 8.59%
This study introduces an end-to-end automatic pipeline to measure and normalize cord CSA from a neurological reference
This approach requires further validation to assess atrophy in longitudinal studies
The inter-subject variability of CSA can be partly accounted for by demographics and anatomical factors
Various neurodegenerative diseases such as multiple sclerosis (MS) are associated with spinal cord (SC) atrophy, which is caused by demyelination, neuronal and/or axonal loss (Lukas et al., 2013; Bonacchi et al., 2020). New techniques have now become available through recent advancement in magnetic resonance imaging (MRI) and are relevant to assess SC atrophy (Moccia et al., 2019)
SC atrophy at the upper cervical levels can be defined within its cross-sectional area (CSA) (Losseff et al., 1996; Lukas et al., 2013)
The use of this metric is yet still limited due to considerable inter-subject variability
Finding factors that contribute to the observed variability is important to improve the SC CSA's sensitivity and specificity
the absence of a statistical difference could be explained by the relatively small sample size (30 participants)
The effect of age on SC CSA needs further investigation
small sample size and narrow range of age are limiting factors to assess the effect of age on SC CSA
A notable difficulty for computing the axial canal area is the ability to properly segment it
brain/skull metrics and sex are important factors to consider in a possible normalization method
the mentioned normalization methods are only reported in the related papers; they are not easily reusable to integrate directly within analysis pipelines
In addition to the biological-derived normalization strategy, previous studies have reported a variability in CSA measures associated with the MRI acquisition parameters, and segmentation method (Kearney et al., 2014; Papinutto and Henry, 2019; Chien et al., 2020; Cohen-Adad et al., 2021)
the PMJ is a more appropriate landmark due to its proximity to the cervical SC
hence limiting the required field of view in MRI scans
compared to conus medullaris which could be more appropriate for lumbar SC measures
While SC CSA variability across participants was shown to be associated with multiple demographic, anatomical and biological factors (Papinutto et al., 2015, 2020; Solstrand Dahlberg et al., 2020; Kesenheimer et al., 2021)
no previous studies have addressed the variability associated with limitation of vertebral based SC CSA measurement in the search for a normalization method of SC CSA at a large scale
In this study we quantify the contribution of various factors on the inter-subject variability in cervical SC CSA measurements. We notably introduce a method to replace the commonly used vertebral-based referencial system (Moccia et al., 2019) by an anatomical reference from the central nervous system to overcome the imprecise prediction of the spinal segments
we (1) establish a fully-automatic MRI data processing pipeline to compute SC CSA
(2) process MRI data from a subset (N = 804) of the UK Biobank database
(3) introduce a method to automatically use the PMJ as a referential system to measure SC CSA
(4) develop a statistical model and normalization method for SC CSA measurements
1,000 participants (48–80 years old
56.3% female) were selected from the UK Biobank database
we could not base this number on any reliable power analysis
the number of participants was selected as a compromise between the statistical power we wanted to achieve in comparison with the previously-published studies addressing similar scientific questions (typically <300 participants) and the time required to manually validate each step of the processing pipeline (visual inspection
manual correction of SC segmentation and/or PMJ labeling and/or vertebral labeling)
Participants with a history of neurological diseases were excluded from the study. Fields from the UK Biobank dataset included in the category Nervous system disorders were used to identify these participants
This brought the number of participants from 1,000 to 972
Data used for this study were unprocessed NIfTI T1w structural scans from the UK Biobank Brain Imaging dataset (Miller et al., 2016)
Images were acquired in four different assessment centers on a Siemens Skyra 3T running VD13A SP4 with a standard Siemens 32-channel receive head coil
T1w structural scan has a field of view of 208 × 256 × 256 with an isotropic resolution of 1 mm3
The superior-inferior field of view of 256 mm typically covers down to C3 vertebral level
which is relevant for the present study as SC CSA was measured around the C2–C3 vertebral level
The UK Biobank data includes preprocessed data (corrected for gradient non-linearity and masked)
however we could not use these data because the SC was masked out
We therefore used the unprocessed T1w images as input of the processing pipeline described in the next section
Data processing pipeline is based on spine-generic v2.6 pipeline (Cohen-Adad et al., 2021) and SCT v5.4 (De Leener et al., 2017). The processing pipeline and its documentation are both available on GitHub.
SC CSA was computed using SCT's sct_process_segmentation with two different methods further explained below
Correction for gradient non-linearities was applied on the T1w image and SC was segmented automatically
and SC CSA was computed at C2–C3 levels
and the centerline was extracted to compute SC CSA from the PMJ
To overcome the limitation of SC segment prediction with vertebral bodies, SC CSA was measured from a distance of a neurological reference; we chose the PMJ (Stroman et al., 2008; Cadotte et al., 2015)
First, the PMJ was identified using SCT'S sct_detect_pmj. Briefly, a 2D support vector machine trained with histogram of oriented gradient features (HOG + SVM 2D classifier) was run on the mid-sagittal slice to detect the PMJ (Gros et al., 2017)
the mid-sagittal slice does not necessarily correspond to the anatomical medial plane if the participant's head is slightly tilted in the scanner for example
We used a sliding window centered on the first estimated PMJ coordinate based on the mid-sagittal plane and computed cross-correlation within the window and its mirror image in the right-left orientation
We assumed that the maximum cross-correlation corresponds to the right-left symmetry slice
The HOG + SVM 2D classifier was run again on the updated medial plane
The SC centerline was extracted from SC segmentation and the PMJ label using linear interpolation and smoothing
The distance from PMJ is measured along the centerline following the arc-length
The extent mask is centered at 64 mm from PMJ
The second and more commonly used method to compute the SC CSA was to use C2–C3 vertebral levels as an anatomical reference for spinal segments (Casserly et al., 2018; Moccia et al., 2019). We proceeded to vertebral labeling using sct_label_vertebrae (Ullmann et al., 2014)
SC CSA was then averaged across C2–C3
these images were excluded from the statistical analysis
This brought the number of participants from 972 to 826
manual corrections were done on the segmentation and/or labeling
Making these corrections ensured that the derived CSA measures are reliable
Segmentations were corrected using ITK-SNAP by adding or removing voxels when appropriate
we manually labeled the posterior tip of the intervertebral discs C1–C2
C2–C3 and C3–C4 using SCT's sct_label_utils
All manual corrections were added to the dataset under the folder “/derivatives/labels” that follows the BIDS convention
The whole analysis was then re-run and when existing
the corrected segmentations/labels were used in lieu of the automatic segmentations/labels
Processing was distributed across 40 CPU cores (one participant per CPU core) using sct_run_batch on a 64-core CPU cluster
To study the relationship between the PMJ-based and vertebral-based CSA measures
we built a scatterplot and derived a model
We also computed the distance between the C2–C3 disc and PMJ
median and coefficient of variation (COV) for both CSA measures were computed
We performed a two-sided paired T-test to assess if there is a statistically significant difference between PMJ-based CSA vs
All subsequent analyses were done on both CSA at 64 mm from the PMJ and at the C2–C3 disc
a T-test for two independent samples was performed to establish if the mean CSA for male and female has a significant difference
We fitted a linear and quadratic regression to assess the effect of age on SC CSA
The level of significance was the same for both entry and exit tests
we proceeded to a residual analysis and computed R2
Pearson's correlation coefficient between candidate predictors was used to choose which parameter to include in the stepwise model due to possible collinearity between parameters
With the best multilinear regression fit, a regression-based residual method (Sanfilipo et al., 2004; Papinutto et al., 2020) was developed using the significant predictors
where CSAmeasi is the computed SC CSA value from a given participant i, CSAnormi is the normalized CSA value, cj are the coefficients of the multilinear regression, Xj, mean are the mean values of all significant predictors, Xj, measi are values for the given participant's predictors, for j predictors (Papinutto et al., 2020)
Since this method assumes that the regression line slopes are parallel for both groups for sex (Sanfilipo et al., 2004)
the interaction between significant predictors and sex was also explored afterward
The interaction term corresponds to the predictor multiplied by sex (0 or 1) as we can see in the following equation:
The effect of normalization was then evaluated by comparing the COV of the normalized SC CSA (CSAnormi) and the measured CSA (CSAmeasi)
We also present the mean (μnorm) and STD (σnorm) of the normalized CSA measures (CSAnormi) and the z-score equation:
In this study we compared SC CSA measured using the PMJ as a reference or the C2–C3 disc as a reference (more popular)
When using the PMJ as a reference (64 mm caudal to the PMJ)
the CSA ranged between 51.9 and 95.6 mm2 (mean ± STD: 66.2 ± 6.69 mm2)
When using C2–C3 vertebral levels as a reference
the CSA ranged between 51.5 and 96.9 mm2 (mean ± STD: 66.4 ± 6.61
Figure 3A shows the relationship between CSA at 64 mm from the PMJ and CSA at C2–C3 vertebral levels. The linear regression led to a R2 of 0.97. Figure 3B shows a scatterplot of the distance from the PMJ and C2–C3 disc
Mean distance from the PMJ to the C2–C3 disc is 64.37 ± 5.53 mm
(A) Scatterplot of PMJ-based CSA at 64 mm and vertebral-based CSA at C2–C3 vertebral levels
(B) Scatterplot of the distance between the PMJ and the C2–C3 disc
We found a significant difference between the CSA calculated at 64 mm from the PMJ and the CSA measured at the C2–C3 disc (paired t-test
Ventricular CSF volume was the only parameter to present a non-significant correlation coefficient with both SC CSA measures (p-value > 0.05)
brain WM and brain GM volume present the highest correlations out of all parameters (Pearson's r > 0.4)
we notice in particular a very strong correlation between thalamus volume and brain
Pearson's correlation among SC CSA
Participants in this study include 43.7% of males and 56.3% of females. Figure 4 presents SC CSA violin plots for female and male with mean and STD
We found a significant difference for CSA between female and male for both CSA at 64 mm from the PMJ and at C2–C3 disc (CSA(PMJ): t = −5.37
(A) Violin plot of SC CSA at 64 mm from the PMJ for female and male with mean (μ) and standard deviation (σ) for each sex and t-value and p-value from the two independent samples t-test
(B) Violin plot of SC CSA at C2–C3 disc for female and male with mean (μ) and standard deviation (σ) for each sex t-value and p-value from the two independent samples T-test
To explore the relationship between age and SC CSA, we calculated a linear and quadratic fit. The age of the participants ranged between 48 and 80 years old. The linear fits are presented at Figure 5
The constant and the linear coefficient are the same for both linear and quadratic fits per CSA methods (PMJ and C2–C3)
The quadratic coefficient is very small for both methods (CSA(PMJ): 9.07 × 10−4; CSA(C2–C3): 4.75 × 10−4)
There is almost no quadratic trend in both cases
(A) Linear fit for CSA at 64 mm from the PMJ as a function of age
(B) Linear fit for CSA at C2–C3 disc as a function of age
Based on the Pearson's correlation analysis presented in Table 1
the following parameters were input in the stepwise linear regression: sex
GM volume and brain volume have a very strong correlation (0.94 and 0.96)
brain WM volume and GM volume were not included in the model to avoid collinearity
The stepwise method yielded a model including brain volume and thalamus volume for CSA(PMJ) and CSA(C2–C3). The resulting model is shown in Table 2 for CSA at 64 mm from the PMJ and at Table 3 for CSA at C2–C3 disc
Adjusted R2 is 0.265 for CSA(PMJ) and 0.271 for CSA(C2–C3)
Both models show a significant association with CSA (p-value < 0.0001)
Multilinear regression analysis for SC CSA(PMJ) (N = 804 participants)
Multilinear regression analysis for SC CSA(C2–C3) (N = 804 participants)
The presented model's coefficients led to the following normalization equation with thalamus volume and brain volume and their respective mean for CSA at 64 mm from the PMJ and at C2–C3 disc
Normalized CSA(PMJ) had a mean and STD of 66.26 ± 5.72 mm2 and for CSA(C2–C3)
With the CSA at 64 mm from the PMJ normalization
COV went from 10.09 (CSAmeasi) to 8.64% (CSAnormi)
With the CSA at C2–C3 disc normalization
COV went from 9.96 (CSAmeasi) to 8.51% CSAnormi) a reduction of 14.61%
Figures 6, 7 show scatterplots of CSA at 64 mm from the PMJ and at the C2–C3 disc with both predictors (brain volume and thalamus volume) separated for sex
we observe that the slopes for female and male are different with the brain volume predictor
however the slopes are closer with the thalamus volume predictor
To quantitatively validate if the interaction coefficient is significant in the model
we computed the interaction of both predictors with sex
The interaction coefficient for brain volume was significant (CSA(PMJ): p-value = 0.006; CSA(C2–C3): p-value = 0.005) and sex was also significant when adding the interaction parameter (CSA(PMJ): p-value = 0.005; CSA(C2–C3): p-value = 0.004)
the interaction coefficient was not significant (CSA(PMJ): p-value = 0.227; CSA(C2–C3): p-value = 0.218) neither was sex (CSA(PMJ): p-value = 0.227; CSA(C2–C3): p-value = 0.213)
The interaction of brain volume and sex was therefore added to the previous model since it has a significant effect
The following equation presents the corresponding normalization equation: CSA(PMJ):
The model was significant (p-value < 0.0001) for both CSA(PMJ) and CSA(C2–C3)
Normalized CSA(PMJ) had a mean and STD of 66.26 ± 5.69 mm2 and for CSA(C2–C3)
The COV of CSA(PMJ) went from 10.09 to 8.59%
The COV of CSA(PMJ) went from 9.96 to 8.42%
Adjusted R2 was 0.271 for CSA(PMJ) and 0.276 for CSA(C2–C3)
Scatterplots of CSA(PMJ) as a function of brain volume and thalamus volume separated for sex with linear fit
Scatterplots of CSA(C2–C3) as a function of brain volume and thalamus volume separated for sex with linear fit
The normalization model has the following equation:
we quantified the contribution of various factors on inter-subject variability in cervical SC CSA measurements in 804 participants with a fully-automatic processing pipeline
We implemented a measurement method for SC CSA that uses the PMJ as opposed to the vertebral reference to overcome its limitations associated with the head position variability
we developed a normalization model which can reduce inter-subject variability by up to 14.85% for CSA(PMJ) or 15.13% for CSA(C2–C3)
Regarding vertebral-based CSA and PMJ-based CSA, COVs are very similar (9.96% C2–C3, 10.09% PMJ) as for CSA values (see Figure 3)
The CSA measures between the PMJ and C2–C3 disc reference were statistically different (p-value = 0.0002)
This suggests that using the PMJ as a reference for CSA measurement is relevant to overcome the imprecise prediction of the spinal segments
This enforces the fact that vertebral levels are not a precise surrogate for spinal levels
there is no clear conclusion if the PMJ-based method reduces the inter-subject variability
which is a relevant indicator in cross-sectional studies (e.g.
used to assess the signature of a biomarker with different phenotypes)
given that head tilting might change across sessions
it is possible that a PMJ-based method is preferred
While no clear conclusion can be drawn from the PMJ-based method in comparison with the vertebral-based method in terms of inter-subject CSA variability
to further investigate the relevance of a PMJ-based method since it is fully-automatic and suggests promising results for longitudinal studies
Some limitations are associated with the PMJ-based CSA method
The use of the PMJ label to interpolate with the centerline is not the exact extrapolation of the centerline
SC curvature at the PMJ varies across individuals
which adds variability to the computed distance
PMJ label positioning across participants may also differ
Moreover, the absolute distance from PMJ doesn't consider the fact that the SC length varies across individuals (Lang and Bartram, 1982; Boonpirak and Apinhasmit, 1994)
Using a relative distance to predict the spinal segments from the PMJ could be relevant to overcome this limitation
Results from this study show a difference between SC CSA using a vertebral-based vs
but not between the inter-subject variability
A comparison with the nerve rootlets is necessary to assess which method ensures proper prediction of the spinal segments; it will be the subject of further investigations
Another question remains about the robustness of the PMJ-based CSA method in the presence of lesions in the brainstem and the spinal cord
The presence of lesions in the brainstem could lower the performance of the automated identification of the PMJ
which needs to be further assessed in pathological data
The other important aspect of the PMJ-based method is the spinal cord centerline
which is extracted from the spinal cord segmentation
the automatic segmentation could also be less reliable
Future developments of spinal cord segmentation algorithms that are robust to the presence of lesions would address this limitation
In the case of high atrophy rate in the brainstem
we expect that it is very unlikely that the PMJ won't be easily identifiable
considering it is the only required label in the brainstem region for this method
we don't expect that the centerline extraction will be affected by lesions in the brainstem since it only relies on the spinal cord segmentation
a high atrophy rate in the spinal cord would affect the spinal cord segmentation
The centerline would lose some precision since it is extracted by computing the center of mass of each slice of the spinal cord segmentation
This could result in loss of precision in the computation of the distance from the PMJ in order to compute CSA
but further investigations are needed to establish the impact of lesions in the brainstem or spinal cord on the PMJ-based CSA method
No significant correlation was found with ventricular CSF volume
Correlations with height and weight are low
It would have been interesting to explore other potential regressors explaining SC CSA
medulla) due to their closeness to the cervical SC
These additional regressors would help elucidate if the strong correlation between the thalamus volume and SC CSA is unique to the thalamus or if it is also found in other structures
We found a statistical difference between SC CSA between male and female; females have a significantly smaller CSA than males as previous studies have shown (Papinutto et al., 2015, 2020; Solstrand Dahlberg et al., 2020)
The interaction between thalamus volume and sex wasn't significant
sex and sex/brain volume interaction led to a COV of 8.59%
a reduction of 14.85 % for CSA(PMJ) and for CSA(C2–C3)
Including sex and brain volume interaction led to the best COV reduction
interaction of sex and brain volume was never considered in previous normalization models
only the fixed effect of sex on CSA was included
These findings reveal the importance to consider that factors can vary differently for males and females
We also proposed a model without the thalamus volume
given the difficulty to measure it (it requires the proper anatomical sequence with sufficient contrast and resolution) and/or in the case of abnormal thalamic atrophy
which could happen in various pathological conditions
This model reduced CSA variability less than when including thalamus volume [11.22% of reduction for CSA(PMJ) vs
brain volume and sex better explains CSA variability
Even if CSA at 64 mm from the PMJ and at C2–C3 disc differed significantly
the normalization analysis and obtained models did not vary and the coefficients of the models were very similar
which impacts the distribution and coverage of the data of the participants and affects the normalization method
Age was not a significant predictor for SC CSA. Trends for CSA and brain volume for the age range of our study are very similar. The effect may differ for younger people since brain volume decreases linearly with age while CSA increases until about 45 years old and decreases afterward (Papinutto et al., 2020)
We have to consider the fact that older people may be more subject to motion in the MRI than younger people (discomfort
difficulty breathing) resulting in a bias in the measured CSA (blurring
Further investigations are needed to validate if the model can expand to ages not included in this study
The normalization model was generated from T1w data with a specific protocol. Subsequent studies should assess whether the model is adequate for other acquisition parameters and contrasts. It is known that the output CSA varies for different acquisition protocols (Cohen-Adad et al., 2021)
since there is a direct relationship between CSA values from different contrasts
there would be a systematic offset in the produced CSA
It is important to note that the choice of processing software package (and its version) used to compute the brain morphometrics affects the measured brain and thalamus volumes, and hence the proposed normalization model. The proposed normalization model would then require data to be processed using the same processing software as that used for the UK Biobank analysis pipeline (Alfaro-Almagro et al., 2018)
intracranial volume could be a relevant substitute for brain volume since it is not affected by neurodegenerative diseases
Including sex interaction here will also be important and can improve the normalization model
Further studies could include intracranial volume in the normalization model
other confounding factors could possibly affect image acquisitions for pathological patients
Severe motor disability could induce some breathing difficulties which induces considerable motion artifacts
This study features an analysis of factors contributing to SC CSA variability at a larger scale than what was done previously to our best knowledge using an automatic processing pipeline
We introduced a new reference in the context of CSA measurements based on a neurological reference (PMJ) to overcome vertebral reference limitations (neck flexion and extension) which sets ground for further investigation regarding the prediction of spinal segments and cervical CSA studies
We computed over a large cohort of participants SC CSA at 64 mm from the PMJ on T1w scans from the UK Biobank database
The pipeline is based on regular brain MRI scans
making it of interest for a broad range of study types
No significant age trend was found while SC CSA was significantly different for males and females
We present an effective normalization model including thalamus volume
sex and sex/brain volume interaction readily usable in SCT
The most relevant factors to explain SC CSA variability are related to the brain; these findings show the importance of having a brain MRI acquisition in SC studies/research
Reducing inter-subject variability could improve comparison between CSA measures to increase its sensitivity and specificity to better assess pathology-related changes

Pieces from Neon Demon Studios will be on display at a pop-up gallery in support of the Junction House development
is a new mid-rise development planned for the Junction
a pop-up gallery of neon displays is headed to the Junction
and the information within may be out of date
the planned neighbourhood development expected to begin construction in the fall
is running a gallery exhibit made up of historic Toronto neon signs
The exhibit will be made up of display pieces collected by a group seeking a permanent museum to house the items
as well as Neon Demon design studio in the east-end where some of the signs are stored but not currently accessible to the public
It will take place April 12-14 daily from 11 a.m
located at the project’s lot space at 2720 Dundas St
The builders of the nine-storey residential tower have applied to the city to install a 32-foot neon sign on the roof which they hope will become synonymous with the neighbourhood
- "Unseasonably warm" conditions Tuesday had fire officials predicting increased burning and smoke will continue to impact the region from the Elk Fire in northern Wyoming
In a Tuesday morning update fire officials said the wildfire in the Bighorn National Forest was now 26 percent contained and had burned 91,905 acres
an increase of 2,590 acres in the last 24 hours
There are currently 939 fire personnel assigned to the blaze that was sparked by lightning on Sept
Key Messages: Expect increased fire activity and smoke today because of unseasonably warm temperatures
Wyoming Department of Transportation (WYDOT) opened portions of US 14 and US 14A previously closed due to the Elk Fire
WYDOT opened US 14 from Greybull to Burgess Junction and US 14A from Burgess Junction to Lovell.US 14 from Burgess Junction east to Dayton remains closed

The team behind southwest Detroit’s Green Dot Stables and Johnny Noodle King are in the process of adding a popular craft cocktail bar to their portfolio
also behind Yellow Light Donuts with a location inside Michigan Central Station in southwest Detroit and an eastside location on Jefferson
are buying the popular Kiesling in the Milwaukee Junction neighborhood
While the Driscolls weren’t in the market for another project
this buying opportunity came up and made sense for them
“We figured out a way for it to financially make sense because it wasn't really in our plans to do another project,” said Jacques Driscoll
who called the Kiesling one of the best bars in the city
what a what an opportunity and it fits into our mold of what we're trying to do within the city.”
formerly of Kamper’s in the Book Tower and Prime Proper in Detroit's Capitol Park area
In Detroit’s evolving Milwaukee Junction area
the Kiesling is known as a hot spot for its deftly crafted original plus classic cocktails and as a place for food pop-ups including regularly featured Tacos Hernandez
a 2024 Detroit Free Press Metro Detroit Chevy Dealers Top 10 Best New Restaurants and dining Experiences
Built by the Kiesling family in the 1890s, the space first operated as a general store, according to its website
Over the decades its name and space changed
It eventually became Edith’s Hideway in the 1970s and was known as a neighborhood watering hole up until the mid-1990s when it closed
Kiesling was reborn in 2018 and since then has celebrated many accolades for its cocktail program
an attached next-door coffee and espresso bar
Gov. Whitmer signs Michigan tipped minimum wage, paid sick leave bills into law
Jacques Driscoll said the plan is to keep the current setup while enhancing it
“This is an opportunity for us to show that we can do all kinds of hospitality … this is like the stuff we love to … I think that we can really excel at,” Jacques Driscoll said
“I think one of the best parts about that bar is you can get a nice cocktail
It's kind of … it's a bar for everybody.”
Financial details of the sale were not revealed
but the business and the building will be bought

Alternative C Kimball Junction traffic mitigation plan
PARK CITY, Utah — The Utah Department of Transportation (UDOT) released its Draft Environmental Impact Statement (EIS) today
selecting a $48.5 million improvement plan for the notoriously congested Kimball Junction area
After evaluating multiple options
UDOT identified “Alternative C: Intersection Improvements with Pedestrian Enhancements” as its preferred solution to address traffic issues where Interstate 80 meets SR-224 in Summit County
Alternative C improvements for Kimball Junction
The plan promises significant traffic flow improvements with specific changes including additional lanes on I-80’s eastbound off-ramp
a third travel lane in both directions on SR-224 from Olympic Parkway to Ute Boulevard
and a new pedestrian undercrossing near Ute Boulevard
Alternative C would reduce average southbound morning travel time from 11:30 minutes to just 3:15 minutes
increasing average speeds from 9 mph to 33 mph
The plan also reduces vehicle queue lengths on I-80 off-ramps from over 5,000 feet to approximately 400 feet
“Alternative C provides the greatest reduction in travel delay and faster travel speeds in the study area during AM and PM peak periods,” UDOT stated in its documentation
The agency noted that all intersections in the study area would operate at acceptable levels of service under the plan
UDOT selected Alternative C over the more expensive Alternative A
which would have cost approximately $123.9 million and featured a split-diamond interchange with intersection improvements
Public hearings are scheduled for April 8 at Ecker Hill Middle School Auditorium and virtually via Zoom on April 10
The public comment period runs through April 28
with UDOT accepting feedback on the preferred alternative
“Today is also the start of the study’s public comment period and we encourage you to take a little time to review our recommendations and let us know what you think,” Utah Department of Transportation posted on a facebook post this morning
