[FC Tokyo Park Fuchu] Announcement of recruitment for participants in the May Promotion Department coaching event About the FC Tokyo Soccer and Futsal School Staff for the 2025 Fiscal Year [Updated: 4/4] FC Tokyo Adult Soccer School Now Open Notice of the Spring Man × J League Special Collaboration Event on 4/11 (Friday) against Kashiwa [May] "FC Tokyo Goalkeeper Clinic" Announcement Recruiting participants for the "Adult Futsal Class in Kodaira Gymnasium" to be held in May 2025 Japanese speed skater Kodaira Nao turned her attention outside her sport in order to find a way to "express the value of sports beyond the gold medal at the Olympics" Picture by 2018 Getty ImagesBy Jo Gunston“When I stood on top of the podium at the 2018 Olympic Winter Games in PyeongChang I realised that I didn't aim to win gold but just to show the best performance of my life to everyone at that moment I want to express the value of sports beyond the gold medal at the Olympics." Accolades followed including the Chino Sports Park International Skating Center in her home city of Chino "Through the 2018 Olympic Winter Games but I also learned from them that I wanted to become a person who can cheer others up.” Kodaira had already shown her compassion in her gold medal-winning race to the Republic of Korea athlete she had beaten to the title. Lee Sang-Hwa had been expected to win her third consecutive title in the event following victories at Vancouver 2010 and Sochi 2014 but made a mistake on the last turn. In tears during the lap of honour, Kodaira approached her competitor and wrapped her in a flag hug. After the Games, Kodaira turned her attention not only homeward but outside her sport. In late 2019, two powerful typhoons – Faxai and Hagibis – caused damage to the nation’s agriculture, forestry and fishing industries, causing extensive destruction across the country including flooding crops and damaging irrigation channels. In Kodaira’s home Prefecture of Nagano, the apple orchards were flooded so in 2020, Kodaira worked as a volunteer in the region's Yamadaino Orchards. View this post on Instagram A post shared by Nao KODAIRA 小平奈緒🍎 (@nao.kodaira) Kodaira wore a red racing suit decorated with an apple motif at the All Japan Single Distance Championships in Nagano in October 2020 in a continued show of support for the relief efforts in the region Still stunned by what happened and the ongoing impact Kodaira posted: "Seeing demolished houses and facilities that were washed away still hurts me." Kodaira's social media feed is still peppered with orchard updates as she heads toward Beijing 2022 I gained the courage that I couldn't get in my daily life or during training,” she posted on Instagram “I want to put this energy on the ice." Hataji and Kodaira share lead at weather-hit ACN Championship Golf Tournament Takahiro Hataji completed 24 holes on Friday to take a share of the second round lead with Satoshi Kodaira at the weather-hit ACN Championship Golf Tournament. Kodaira who held the first round lead at six-under through 12 holes also returned to finish his remaining six holes signing for a six-under-par 65. Barely an hour later Hataji and Kodaira were back at the starting tee to commence their second round where Hataji continued where he left off with another birdie blitz. He stormed ahead with four birdies on holes two then added four more birdies in his back-nine for a bogey-free 63. Reflecting on his marathon round Hataji credited his good fortunes for ensuring he heads into the weekend in a commanding position again. "I guess it's luck and I started the morning by missing a 70cm par putt things started to turn around and I ended the first round with 4-under. “I began the second round with that momentum My shots weren’t that great but I made several 5-6 meter putts and managed to ride on that luck This is because when so many 5-6 meter putts go in It feels like that kind of day when the putts are just dropping." “Yesterday I spent over five hours waiting before starting my round this tournament has been particularly draining," said Hataji. While Hataji took advantage of his putting prowess Kodaira relied on his iron play to put him in contention for his eighth win on the JGTO as he shares the lead with Hataji with their matching two-day total of 12-under-par 130. "My shots have been really good over the last two days I found something during the practice rounds it brought me back to the feeling I had when I was playing well in the past. My shots are really solid I didn’t sink enough putts and that can be a bit frustrating for me." "If I can get my putting right I’d like to be in a position to aim for the win by the back nine on the final day I'll work on improving bit by bit to make that happen," said Kodaira. 12 players have yet to complete their second round as it had to be suspended due to darkness It will resume at 7:30am on Saturday morning with the third round expected to start at 9:30am.

On Sunday, he gets a chance to create new memories as he chases a home victory at the ZOZO CHAMPIONSHIP. The 34-year-old Kodaira fought to a 1-under 69 in the third round for tied fifth place, just three strokes back of leader Justin Suh who earned his career first 54-hole lead on 9-under after a 67 put him in pole position for a maiden PGA TOUR title. Overnight leader Beau Hossler (69) and rookie Eric Cole (66) share second place, one stroke back, while two-time major winner Collin Morikawa brilliantly signed for a 66 after going 3-over in his opening five holes at Accordia Golf Narashino Country Club for solo fourth on 7-under. Satoshi Kodaira's tee shot to 7 feet sets up birdie at ZOZO CHAMPIONSHIP As quickly as Kodaira rose to fame when he stunned a top field for his triumph at the 2018 RBC Heritage, he has slipped off the grid without a single top-10 since enjoying the career breakthrough. “I’ve almost forgotten what that win was like, but I’ve started to recall what being in contention feels like,” said Kodaira, who played in the final group alongside Hossler and Suh. “I’ve had a lot of great experiences since my win but I’m not always in contention unfortunately.” Playing on a sponsor exemption, staying patient, especially when high winds wreaked havoc on Friday, has helped him emerge as Japan’s best hope to secure a second victory in the ZOZO CHAMPIONSHIP on Sunday following Hideki Matsuyama’s famous triumph in 2021. Ryo Ishikawa, who has enjoyed stints on the PGA TOUR previously, enters the final round in tied eighth, five off the lead. Ryo Ishikawa nearly chips-in for eagle at ZOZO CHAMPIONSHIP “I know I have to be more patient when I play which is probably helping me at the moment,” said Kodaira, who made two birdies against a lone bogey in his third round. “I know it’s not over until it’s over, and I can only focus on my own game.” With seven wins on the Japan Golf Tour, which is co-sanctioning this week’s US $8.5 million event, Kodaira is excited at the opportunity to snap a five-year winless drought and knows there will be pressure on his slender shoulders to come from behind and deliver in front of his home fans. When he won at the RBC Heritage, the Japanese overturned a six-shot deficit on the last day. “There’s nerves, the atmosphere of the crowd, and other players are playing great,” he said. “It’s a joy to play and just to play in that atmosphere. I know there will be nerves tomorrow but I hope I can turn that into confidence and end on a high before I go back to the States.” Copyright © 2025 PGA TOUR, Inc.

We assume that people can travel between any pair of locations. Technically, this assumption corresponds to the case of complete graphs in the method’s general description (see Methods for the details) we consider the net flow of movement from a given OD matrix M as when 150 persons move from location i to another location j and 50 people move in the opposite direction we consider the net movements of 100 persons from i to j where $M^{\intercal }$ denotes the transpose of M and is possibly described by combinatorial gradient of a potential s we define the optimisation problem for potential s: According to the combinatorial Hodge theory11 the space of net flow ${\mathcal {A}}$ is orthogonally decomposed into two subspaces: where $\text {curl}$ is the combinatorial curl operator and $\text {curl}^*$ is its adjoint operator the optimisation problem is equivalent to an $l_2$-projection of A onto im(grad) and the minimal norm solution is simply given by where $s_i$ is the potential at the ith location and N is the number of locations. Using equation (1) Note that $s_i$ is negative potential ($s_i=-V_i$) This means that we see more trips from a location with low potential to another with high potential The matrix A is orthogonally decomposed into gradient and curl components To determine how well the potential describes human flow we define the percentage of gradient component as: This quantity is known as the ‘coefficient of determination’ in statistics It is a reasonable choice for assessing the explanatory power of the potential which is determined using orthogonal projection and is similar to ordinary least squares we will show the values of $R^2$ as percentages by multiplying 100 Before investigating the potential of human flow in real cities we validate potential extraction methods by benchmark tests for which the OD matrix was synthetically derived from a given potential ${\bar{V}}$: where $[x]_+ = \max (0,x)$ is a rectifier to ensure positive trips we treat ${\bar{V}}$ as the “ground truth” of the potential We validated the extracted potential ${\hat{V}}$ from the synthetic OD matrix ${\bar{M}}$ by comparing with this true potential and calculated the mean squared error (MSE): the potential is standardised such that its maximum value matches with the reference value ($V=0$) (d-f) single peak situation is similar to the point peak situation but the central place has some spatial extents (d) The potential is estimated by the previous method (e) and the proposed method (f) (g-i) double peak situation represents a polycentric city in which there are two attractive places (g) The potential is estimated by the previous method (h) and the proposed method (i) (j-l) In the restricted area situation (j) the potentials at some locations (white cell) are not available (NA) These NA locations cannot be the origin or destination of flow The potential is estimated by the previous method (k) and the proposed method (l) This suggests that the area near the centre is differentiated from more peripheral areas by the potential ${\hat{V}}$ This is inconsistent with the ground truth of the city structure in which all the locations are identical except for the central point the central area by ${\hat{V}}$ appears larger than its actual size the previous method would be unsuitable for discussing polycentric structures within metropolitan areas it identifies those locations as a part of a central area The potential at a non-land cell or restricted area would be difficult to interpret These observed deviations from the true potential ${\bar{V}}$ are quantitatively measured in terms of mean squared error. Although the large errors obtained via the previous method are partly caused by inconsistencies in the generation process of the OD matrix by equation (8) the concepts of the investigated situations are generic and independent of the specific equation The conversion process from the place-to-place flow to the 2D vector field discards the essential information of the urban structures represented in the given flow it should be noted that these benchmark examples are not unduly detrimental to the previous method It is actually advantageous: the method requires flows to be provided at grid points are typically aggregated by administrative units in survey-based collections or Voronoi polygons of cell towers in call detail records (CDRs) of mobile phones necessitating some resampling treatments to grid points the proposed method is applicable to the OD matrix aggregated by any shape of the geographical zones As a first demonstration, we show the potential landscape in Greater London in 2011, using a person-trip dataset from home to workplace. The OD matrix shows the number of commuters aggregated by the middle layer super output area (MSOA) in the 2011 census (see "Methods" for details) The trips were categorised based on the method of travel used for the longest part by distance We first show the potential by all the methods and then by specific transport methods This allows us to investigate the urban structures from different viewpoints through transport methods Negative potential $-V$ of the home-work trips in London (a) The potential at a place is indicated by its colour and its height (b,c) The potentials are depicted for the selected trips by specific transport methods and the other locations have very low potentials without small peaks the potential amplitude is smaller than that for other cases reflecting the volume of commuters (public transport = 1.6 million trips Next, we demonstrate how the urban structures in Tokyo have either changed or remained unchanged over 30 years in terms of the time evolution of the potential landscape. We used the commuter datasets of successive person-trip surveys from 1988 to 2018 in the Tokyo metropolitan area (see "Methods" for details) Time-evolution of the potential landscape in Tokyo metropolitan area The potentials are obtained from the home-work trips of successive surveys over 30 years in the Tokyo metropolis and surrounding provinces Each zone is basically equal to a municipal district the metropolitan area is given by core-based statistical area (CBSA) a standard definition of the geographical area of cities The dataset covers almost all CBSAs in the USA and compares the percentage $R^2$ across many metropolitan areas Percentage of gradient component $R^2$ in human flow (a) Percentage $R^2$ in home-work trips for each Core-based statistical area (CBSA) in 2018 CBSAs are classified into metropolitan statistical areas (MSAs) and micropolitan statistical areas ($\mu$SAs) (c) Percentage $R^2$ is plotted against the population of the CBSAs it is clearly shown that some cores have emerged over the years as new peaks in the potential landscape We first discuss the practical meaning of the potential we introduced. According to equation (6) the potential is clearly interpreted as the difference between incoming and outgoing flux of people a location with a greater incoming flow from other locations and a smaller outgoing flow to other locations becomes a location with a higher potential The total balance of incoming and outgoing flux determines the attractiveness of a location in terms of potential s human flow has been discussed in terms of paired locations: origin and destination The circulation along triangle places addresses a new aspect of human flow with another question: What drives the circular flows in populated areas The decomposition method opens up new research avenues in human mobility and urban structures the potential landscape by Hodge–Kodaira decomposition provides an intuitive perspective of human flow by its gradient flow from a higher place to a lower place The landscape allows us to understand the spatial structure of cities based on human movements rather than administrative circumstances and to study the dynamic changes in the spatial structure under different conditions we can study whether the global increase in remote workers due to the COVID-19 pandemic is alleviating over-concentration of population in city centres by checking the emergence of new potential peaks in suburbs or the decline of pre-existing ones The method provides an easy-to-use visualisation tool to show the places attracting human flow and will aid relevant applications in commerce The origin-destination (OD) matrix M is a square matrix that represents the number of trips from origin i to destination j by its elements $M_{ij}$ Any square matrix M is uniquely decomposed into a symmetric and a skew-symmetric matrix where $M^{\intercal }$ is the transpose of M The symmetric part can be further decomposed into diagonal and off-diagonal elements The former represents a self-loop flow at each location The latter part is the bidirectional circulation of people between two locations Although investigating these symmetric elements would be interesting we will concentrate on the skew-symmetric part because it may be described by the gradient flow we analyse A ($= M - M^{\intercal }$) by multiplying the skew-symmetric part by 2 The matrix A represents the net movement of human flow by removing the self-loop and bidirectional circulations the combinatorial gradient operator and combinatorial curl operator are defined as follows: the space of edge flow ${\mathcal {A}}$ is orthogonally decomposed into three subspaces where ker($\Delta _1$) = ker(curl) $\cap$ ker(div) and $\text {curl}^*$ is the adjoint operator of the curl With a Euclidean inner product in the space ${\mathcal {A}}$ $\langle X,Y\rangle = \sum _{ \{i,j\} \in E} X_{ij}Y_{ij}$ where $\Delta _0$ is the graph Laplacian of graph G and the divergence is (div A)(i) = $\sum _{j \text { s.t Potential s with the minimal norm is given by where \(\dagger$ denotes the Moore-Penrose inverse the vector potential $\Phi$ of curl flow is derived as the OD matrix $M_{ij}$ is converted into a 2D vector field $\mathbf {W}_i$ by averaging all trips from each location i: where $\mathbf {u}_{ij}$ is the unit vector from location i to location j the empirical potential V is numerically computed on a square grid For a cell i with indices ($\alpha ,\beta$) on the grid the equation $- \nabla V_i = \mathbf {W}_i$ is discretised by The dataset covers the MSOAs in England and Wales we selected only the trips among the MSOAs in Greater London The resultant matrix contains 2.9 million trips between 983 MSOAs The trips in the dataset are categorised by main transport methods used for the longest part and we selected the following two types of transport methods: “Public transport” includes the trips by underground “Private car” includes the trips by driving a car The datasets were categorised according to the purpose of trips and one-directional trips from home to the workplace were selected The OD matrix denotes the number of commuters aggregated by middle-sized geographical zones A middle-sized zone is essentially equivalent to a municipal district with the exception that some zones in rural areas contain several districts The zones have been altered by municipal mergers and dissolutions between 1988 and 2018 and the target regions of the surveys have been extended We selected the areas covered by all surveys from 1988 to 2018 and have a surjective mapping from the zones in 2018 to make shapefiles before 2018 (The shapefile was available only for the last survey in 2018) The resultant matrix contained 11.77 million trips among 121 zones in 2018 11.74 million trips among 120 zones in 2008 10.97 million trips among 114 zones in 1998 and 9.97 million trips among 106 zones in 1988 depending on whether the population is larger than 50,000 Person-trip datasets and the census data that support the findings of this study are publicly available, as noted in the "Methods" section The code is available in the GitHub repository at https://github.com/TakaakiAokiWork/HodgePotentialHumanFlow/ Empirical mathematical rules concerning the distribution and equilibrium of population Equilibrium values and dynamics of attractiveness terms in production-constrained spatial-interaction models The P1 P2/D hypothesis: On the intercity movement of persons The role of transportation and the bases for interaction (ed.)

Cup wins in the 500 and 1,000 meters "The last race of my athletic career will be the 500 meters at the national single-distance championships in October this year," she said of the Oct to be held in her home prefecture of Nagano "I wanted to skate one more race while I have some control over my body and I wanted to race my last race in my home of Shinshu (the name of the region Nagano is also known for)," she said As one of Japan's most prominent speed skaters the 35-year-old competed at four consecutive Winter Olympics from the 2010 Vancouver Games and has long been one of the dominant forces in women's sprint races She captained the entire Japan delegation at her best Olympics in 2018 when she also claimed a silver in the 1,000 to add to the gold she won in her pet 500 event An ankle injury hindered her at the Beijing Games in February where she finished 17th in the 500 and 10th in the 1,000 "I had been thinking my last Olympics would likely be Beijing It's about the right time to take the next step forward in my life," said Kodaira who has been speaking to people around her since last summer about her future Kodaira had tears in her eyes as she looked back on an illustrious career that began when she was 3 and took her to the Netherlands for two seasons of training after the 2014 Sochi Games Her spell in Europe played a huge part in her dominance that really kicked off in her late 20s While maintaining her form with a low center of gravity she straightened up her upper body more following advice from star Dutch skater Ireen Wust en route to winning her first World Cup event in November 2014 and a formidable 37 straight events at home and abroad in the 500 between 2016 and 2019 "I wouldn't have thought I'd meet this many people and learn as much as I have It's really been a wonderful skating career," she said "I can choose to continue to skate (at the top level)...(but) it might be a good timing thinking of my long life ahead I'm really interested in the world which has lots of things I don't know yet." "Until October I'll be training and taking part in local community events but it would be nice to have the opportunity to take to the ice with junior-level skaters."

It doesn’t matter when we get together. It always feels like I was with her until the day before. She’s that kind of friend. “My career was full of peaks and valleys, like a rollercoaster. Thanks to so many people, I managed to never look back; I kept going forward with my chin up.

Kodaira only hopes her successors will have an opportunity like she did with Lee, which she believes was only made possible by the stage known as the Olympic Games. “The Olympics is very important to athletes. Or I hope it is, anyway. For anyone involved in sport - whether you’re competing or working with those competing, whatever the role - I really hope it remains a precious thing. “I’ve experienced four Olympics and I’m convinced it is a place that’s helped me grow. I hope it will continue to be a platform that will help make the world a brighter place, bring together people from all corners.” View this post on Instagram A post shared by Sang Hwa LEE 이상화 (@sanghwazz) Japan's Nao Kodaira wrapped up her storied speed skating career Saturday by winning her eighth straight women's 500 meters at the national single distance championships in her native Nagano Prefecture the 2018 Pyeongchang Olympic 500-meter champion clocked 37.49 seconds at the M-Wave ice arena in Nagano that was packed with a home crowd of 6,085 eager to witness her last hurrah and her 13th career national 500 title In a surprising display for someone about to retire from competition Kodaira showed great cornering ability as well as tenacity in the final stretch to better her time from last season's opening event "I'm filled with joy to have skated at the end (of my career) on the stage I've dreamed of," said Kodaira referring to the 1998 Nagano Olympics venue "I'd have started crying if I looked at everyone's faces I just concentrated on the ice in front of me Kodaira appeared in four straight Winter Olympics starting with the 2010 games in Vancouver where she won silver in team pursuit she captained Japan's delegation and also won silver in the 1,000 Kodaira won 37 consecutive international and domestic 500-meter races between 2016 and 2019 and a total of 34 World Cup titles in the 500 and 1,000 She announced her intention to retire in April but has been training vigorously solely for this last race -- to a level where coach Masahiro Yuki said there would be "no drop off" in performance the 1,000 gold medalist at this year's Beijing Olympics where she won four medals in total "I've learned what a great athlete she is the hard way I hope to get as close to her as I can," said Takagi after finishing runner-up to her great rival "I believe I could not have brought out my best without the presence of my rivals."

Kodaira had finished off his round of 66 to get to 12 under par about an hour before Kim finished. Kodaira matched Kim with two pars on the 18th hole before rolling in his winning putt on the par-3 17th. Kim came up short on his 21-footer for birdie to keep the playoff going. Bryson DeChambeau (66) and Luke List (72) were tied for third. Third-round leader Ian Poulter's bid for a second TOUR title in three weeks ended with a 75 and a tie for seventh. Kodaira, 28, is ranked 46th in the world. He has won three tournaments in Japan and played in the Masters last week, finishing tied for 28th. Start times were pushed up Sunday morning because of bad weather forecast for later in the day. The tournament appeared in steady hands with Kim, whose bulldog focus and shot-making held everyone off to win The PLAYERS Championship last May. But the 22-year-old faltered over his final nine holes of regulation with three bogeys to fall into the tie with Kodaira. Kim thought the increased winds slowed down the greens, making putts more difficult on the final nine holes. "But I tried my best and the putts didn't drop," Kim said. "It is what it is." Poulter, who dramatically won the Houston Open two weeks ago for his first TOUR win in more than five years, had six bogeys Sunday after making just two in his first three rounds. Kodaira was the hardest charged and few even realized until the final threesome of Kim, Poulter and List all came back to the pack. Playing Harbour Town for the first time, Kodaira opened with a 73, then followed with the tournament's best round of the week, 63, on Friday. That game kicked in once more in the final round, with six birdies on the way to the playoff. DeChambeau, the 24-year-old second-round leader who fell apart with a Saturday 75, bounced back Sunday with a 66 to finish two shots back. His roller coaster of a tournament played out again Sunday as he rose three shots to 9 under, then fell back to 7 under before closing with consecutive birdies on the 15th, 16th, 17th and 18th holes. World No. 1 Dustin Johnson finished with his best round of the week, a 67, and was tied for 16th, good enough for him to keep the top spot for a 61st consecutive week. He will take the next three weeks off, starting with a vacation to the Bahamas --"I'm headed there right now," he said, smiling -- until he returns to action at The PLAYERS Championship. Johnson said his problem this season has been on the greens, calling his putting subpar from what he expects. He said he plans to work things out over the break and "be ready for the PLAYERS." Threatening storms forecast for late Sunday afternoon and early evening forced the PGA TOUR to move up start times to 7 a.m., with the leaders going off about two hours later. The weather, while overcast and windy at times, remained calm enough to get in the final round without disruption. – On a day when some of the biggest names in golf struggled to get on the birdie train at TPC River Highlands Japan's Satoshi Kodaira rode the express to the top the leaderboard 294 in the Official World Golf Rankings coming into this week combined pinpoint accuracy from the fairway with a hot putter to card four birdies on Nos he went birdie-eagle-birdie to start his second nine who shot a 7-under 63 in the morning wave to take the early lead a bogey dropped Kodaira back into a tie with Hickok at 7 under it was easily the best round of the season for the 31-year-old "(I) had a good flow going at the beginning of the round and so it felt really good," Kodaira said afterward "Before the round I wasn't thinking this way but I been playing well these few tournaments so I felt really well going into this round."

birdie on the par-3 17th hole It ended a drama-filled final round in which it appeared that Kim Ian Poulter and Luke List had the lock on the title at different points But it was Kodaira’s relentless grind to the top that won the day And with the game he showed at Harbour Town Golf Links Kodaira appears like he’s got more big moments on tour ahead like countryman and five-time tour winner Hideki Matsuyama “I feel like I’m getting closer to that level,” said Kodaira who is ranked 46th in the world and has played in 15 tour events “I’d like to do my best in major championships and Bryson

the chance to win in regulation but missed a six-foot birdie putt on the 18th hole Kodaira said that was the most nervous he was during his wait of about an hour before the playoff Kodaira might have had a few butterflies on the final playoff hole as Kim had a 21-foot birdie try to extend things Kim thought the increased winds slowed down the greens making putts more difficult on the final nine holes “But I tried my best and the putts didn’t drop,” Kim said who dramatically won the Houston Open two weeks ago for his first tour win in more than five years had six bogeys Sunday after making just two in his first three rounds Kodaira was the hardest charged and few even realized until the final threesome of Kim Poulter and List all came back to the pack Kodaira became the sixth straight

tournament played out again in the final round as he rose three shots to 9-under then fell back to 7-under before closing with consecutive birdies on the 15th Dustin Johnson finished with his best round of the week 1 in the world for at least the next two weeks starting with a vacation to the Bahamas —“I’m headed there right now,” he said smiling — until he returns to action at The Players

A series based on diplomatic documents declassified by Japan’s Foreign Ministry Here is a collection of first-hand accounts by “hibakusha” atomic bomb survivors chefs and others involved in the field of food introduce their special recipes intertwined with their paths in life A series about Japanese-Americans and their memories of World War II In-house News and Messages No reproduction or republication without written permission Twenty-eight-year-old Tokyo native Satoshi Kodaira grabbed the first PGA Tour victory of his career by firing a final-round 66 at Harbour Town and then outlasting Si Woo Kim in a playoff Kodaira has six victories on the Japan Golf Tour but will now compete on the PGA Tour for the rest of the season Here’s a full list of gear Kodaira used to take home the $1,206,000 winner’s check: Driver: PRGR RS prototype (10.5°) with Graphite Design Tour shaft Fairway Woods: TaylorMade M2 (15°) with Graphite Design Tour shaft PRGR iD Nabla (18°) with Graphite Design Tour shaft Buy Now Irons: PRGR iD Nabla RS Tour (3) with Graphite Design Tour shaft PRGR Tune Forged (4-PW) with True Temper Dynamic Gold Tour Issue shafts Fourteen RM-22 (60°) with True Temper Dynamic Gold Tour Issue shafts Ball: Titleist Pro V1x Buy Now Metrics details Dose assessment on the lunar surface is important for future long-term crewed activity In addition to the major radiation of energetic charged particles from galactic cosmic rays (GCRs) neutrons and gamma-rays are generated by nuclear interactions of space radiation with the Moon’s surface materials We obtained neutron and gamma-ray ambient dose distributions on the Moon using Geant4 Monte Carlo simulations combined with the Kaguya gamma-ray spectrometer measurement dataset from February 10 to May 28 The neutron and gamma-ray dose rates varied in the ranges of 58.7–71.5 mSv/year and 3.33–3.76 mSv/year depending on the lunar geological features The lunar neutron dose was high in the basalt-rich mare where the iron- and titanium-rich regions are present the lunar gamma-ray dose map was similar to the distribution of natural radioactive elements (238U although the GCR-induced secondary gamma-ray dose was significant at ~ 3.4 mSv/year The lunar secondary dose contribution resulted in an additional dose of 12–15% to the primary GCR particles Global dose distributions on the lunar surface will help identify better locations for long-term stays and suggest radiation protection strategies for future crewed missions The lunar radiation environment includes not only primary charged particles but also secondary neutrons and gamma-rays which are generated by the nuclear interactions of primary particles with the Moon’s surface materials as well as natural radioactive nuclides such as 238U While a large part of the exposure rate on the lunar surface is due to the primary charged GCR particles secondary radiation of neutrons and gamma-rays produced by their nuclear interactions with surface materials also contributes partially to the radiation dose Although some previous lunar exploration missions have measured neutrons and gamma-rays using remote sensing in planetary sciences based on lunar geology The ambient doses of neutrons and gamma-rays were calculated for selected lunar surface compositions the global distribution of the ambient dose was derived using the KGRS observation data on the fast neutron flux and gamma-ray energy deposition rate direct dose measurement was not conducted due to restrictions in energy ranges of neutron and gamma-ray measurements which substantially underestimates the measured doses we employed their relative variations normalized by the average of entire Moon to obtain the global dose distribution from the limited calculation points The measured relative neutron fluxes and gamma-ray energy deposits at the Apollo and Luna sampling sites and the feldspathic highland terrain (FHT) were compared to the calculated neutron and gamma-ray ambient doses to derive the correlation between them The measured values for the FHT were obtained by averaging over the northern far-side quarter of the lunar surface The physics list of Shielding was employed by default were used to estimate the uncertainty based on the Geant4 physics model Feldspathic lunar meteorites were included as a representative composition of feldspathic highland terrain (FHT) for which there were no returned samples The density of the modeled lunar surface was set to 1.6 g/cm3 The ambient dose conversion coefficients for neutrons and gamma-rays26. The calculated neutron and gamma-ray energy spectra for the Apollo 16 returned sample composition Table 2 shows the calculated ambient doses of neutrons and gamma-rays induced by the GCR H based on the reference Apollo 16 sample composition The GCR H and He contributed ~ 94% of the total ambient dose for both neutrons and gamma-rays we derived the total ambient dose due to GCR particles by multiplying the ambient dose due to GCR H and He by a factor of 1.06 to consider heavy ion contributions for the other sample compositions The gamma-ray energy spectrum observed by the KGRS for the entire Moon28 which were induced by inelastic scattering between fast neutrons and germanium nuclei We employed the reported distribution of the fast neutron flux The relative gamma-ray energy deposit distribution was derived by integrating the product of the count rates Ci and energy Ei at each channel i: Relationship between the calculated ambient doses and the KGRS-measured (a) relative fast neutron flux and (b) relative gamma-ray energy deposition rate The (a) neutron and (b) gamma-ray ambient dose distributions on the entire lunar surface Table 4 presents the differences in neutron and gamma-ray ambient doses among several physics models While the gamma-ray contributions by the GCR protons were similar among the physics models the other particle contributions varied by 27–45% depending on the models The variation in the neutron dose caused by the GCR protons was the most significant The Shielding physics list employed to obtain the above correlation provided the most significant ambient dose of GCR H and a small ambient dose of GCR He This dependence may provide additional uncertainty to the results depending on the calculation models While the dose due to GCR secondary gamma-rays was almost constant at ~ 3.4 mSv/year among the lunar samples the natural radioactive gamma-ray doses ranged from 0.017 to 0.46 mSv/year which defined the regional variation of the gamma-ray ambient dose on the lunar surface The contribution of GCR secondary gamma-rays sufficiently occupies the lunar gamma-ray ambient dose whereas regional variation is attributed to natural radioactive elements The dose contribution of GCR secondary particles should be considered for the space crew’s career dose limit Strategic radiation protection for secondary particles is required for future crewed lunar and planetary missions One possible explanation is that the igneous activity of the Earth transports incompatible natural radioactive nuclides to the surface whereas lunar activity is already inactive The lunar terrestrial dose level is very low and not significantly different from that on Earth If the GCR exposure can be sufficiently relieved a similar safe radiation environment can be achieved on the Moon Global lunar dose distributions of neutrons and gamma-rays were evaluated by combining Monte Carlo simulations with the Kaguya gamma-ray spectrometer dataset The neutron and gamma-ray doses varied in the range of 58.7–71.5 and 3.33–3.76 having distributions relating to lunar geologic features The neutron dose distribution was similar to that of lunar mare materials which have a large average atomic mass owing to their fast neutron production rates The gamma-ray dose variation depended on lunar natural radioactive elements whereas the GCR secondary gamma-ray dose was significant Although the GCR secondary dose rates were smaller than the primary GCR dose rates they contributed an additional 12–15% dose depending on the lunar region These rates will not be negligible for future human space activities Radiation protection against these secondary particles is also important as is that against the primary GCR particles Lunar global dose maps will help identify better locations for long-term stay and suggest radiation protection strategies for future crewed missions The data sets generated in this study are available from the corresponding author upon reasonable request There are no restrictions on data availability Alan Stern, S.

"I don't know whether it is okay for me to say this or not but Sumiyoshi's people told me before the Olympics that she had said to them if I get the gold it would be the same as her winning it." "I actually won the gold medal but I wanted to tell her about it in person and it is such a shame that I am not able to do that." Sumiyoshi was in the same year at Shinshu University as Kodaira who in addition to winning the 500 gold in an Olympic record time also won the silver medal in the 1,000 last Wednesday Sumiyoshi failed to make the team for Pyeongchang Kodaira upstaged two-time defending Olympic champion and close rival Lee Sang Hwa in front of the South Korean home fans to win the women's 500 gold Kodaira said after Sunday's race that she had drawn courage from Hanyu's performance "I watched Hanyu perform on television and when he stood on the rink just before he started Just by looking at him I could tell he would succeed," she told Monday's press conference "I thought to myself I would like to have the same aura I know he has been reading a lot of literature on injuries and I would like to talk to him and find out what he has been reading." Kodaira's gold was the first by a Japanese female speed skater and Japan's first in the sport since Hiroyasu Shimizu won the men's 500 on home ice at the 1998 Nagano Olympics Kodaira also broke a jinx and became the first Japanese Winter Olympic team captain to win a gold medal "When I accepted the offer to be captain I felt a bit shy because I am not very good in front of people and I had heard the jinx about captains not being able to win gold medals," said Kodaira "To be honest I didn't want to be the captain but (coach Masahiro) Yuki-sensei persuaded me and I wondered what I could learn from the experience in the future." "I took on the role and didn't really think about the gold medal jinx and just focused on what I had to do I can lend my support to the team and I will be getting behind the men in the (speed skating) 500 tonight."
