This image was created by simulating the formation of our galaxy using a supercomputer, which, in this case, consisted of 2,000 computers linked together. Credit: Hopkins Research Group/CaltechAstronomers have created the most detailed computer simulation to date of our Milky Way galaxy’s formation, from its inception billions of years ago as a loose assemblage of matter to its present-day state as a massive, spiral disk of stars.The simulation solves a decades-old mystery surrounding the tiny galaxies that swarm around the outside of our much larger Milky Way. Previous simulations predicted that thousands of these satellite, or dwarf, galaxies should exist. However, only about 30 of the small galaxies have ever been observed. Astronomers have been tinkering with the simulations, trying to understand this “missing satellites” problem to no avail.Now, with the new simulation—which used a network of thousands of computers running in parallel for 700,000 central processing unit (CPU) hours — Caltech astronomers have created a galaxy that looks like the one we live in today, with the correct, smaller number of dwarf galaxies.“That was the aha moment, when I saw that the simulation can finally produce a population of dwarf galaxies like the ones we observe around the Milky Way,” says Andrew Wetzel, postdoctoral fellow at Caltech and Carnegie Observatories in Pasadena, and lead author of a paper about the new research, published August 20 in Astrophysical Journal Letters.One of the main updates to the new simulation relates to how supernovae, explosions of massive stars, affect their surrounding environments. In particular, the simulation incorporated detailed formulas that describe the dramatic effects that winds from these explosions can have on star-forming material and dwarf galaxies. These winds, which reach speeds up to thousands of kilometers per second, “can blow gas and stars out of a small galaxy,” says Wetzel.Indeed, the new simulation showed the winds can blow apart young dwarf galaxies, preventing them from reaching maturity. Previous simulations that were producing thousands of dwarf galaxies weren’t taking the full effects of supernovae into account.“We had thought before that perhaps our understanding of dark matter was incorrect in these simulations, but these new results show we don’t have to tinker with dark matter,” says Wetzel. “When we more precisely model supernovae, we get the right answer.”Astronomers simulate our galaxy to understand how the Milky Way, and our solar system within it, came to be. To do this, the researchers tell a computer what our universe was like in the early cosmos. They write complex codes for the basic laws of physics and describe the ingredients of the universe, including everyday matter like hydrogen gas as well as dark matter, which, while invisible, exerts gravitational tugs on other matter. The computers then go to work, playing out all the possible interactions between particles, gas, and stars over billions of years.“In a galaxy, you have 100 billion stars, all pulling on each other, not to mention other components we don’t see like dark matter,” says Caltech’s Phil Hopkins, associate professor of theoretical astrophysics and principal scientist for the new research. “To simulate this, we give a supercomputer equations describing those interactions and then let it crank through those equations repeatedly and see what comes out at the end.”The researchers are not done simulating our Milky Way. They plan to use even more computing time, up to 20 million CPU hours, in their next rounds. This should lead to predictions about the very faintest and smallest of dwarf galaxies yet to be discovered. Not a lot of these faint galaxies are expected to exist, but the more advanced simulations should be able to predict how many are left to find.The study, titled “Reconciling Dwarf Galaxies with ?CDM Cosmology: Simulating A Realistic Population of Satellites Around a Milky Way-Mass Galaxy,” was funded by Caltech, a Sloan Research Fellowship, the National Science Foundation, NASA, an Einstein Postdoctoral Fellowship, the Space Telescope Science Institute, UC San Diego, and the Simons Foundation. Other coauthors on the study are: Ji-Hoon Kim of Stanford University, Claude-André Faucher-Giguére of Northwestern University, Dušan Kereš of UC San Diego, and Eliot Quataert of UC Berkeley.

Carlton Fields celebrates 100 years with community service programs

first_img August 1, 2002 Regular News Carlton Fields celebrates 100 years with community service programs Carlton Fields celebrates 100 years with community service programscenter_img In celebration of its centennial year, Carlton Fields law firm is giving a number of birthday gifts to each of the communities where it has offices.“Carlton Fields is blessed with a rich history and tradition of service to its clients, the profession, and its several communities throughout the state of Florida,” said Tom Snow, Carlton Fields’ president and CEO. “We have always believed that if we are successful in those three endeavors we will be successful as a firm and as individuals. Our centennial projects are just a snapshot of what this firm has appropriately and gladly undertaken to give back to our communities.”Wm. Reece Smith, Jr., the firm’s chair emeritus, said he wonders what founder Giddings Mabry would think of the firm today. In 1901, Mabry, then age 24 and just graduated from the South’s only law school — Cumberland, in Lebanon, Tennessee — created the firm in Tampa.“Today we are a talented, well run firm that is nationally recognized not only for the outstanding abilities of its lawyers but also for their unselfish pro-bono service on behalf of the less fortunate,” Smith said. “We are known, too, for providing a benign, family-friendly and gender-friendly place to work. We have awards to prove it. We have progressed. But in order to continue that progress we must hold to the values we have developed collectively in our century of effort.”The Tampa office has adopted the Child Abuse Council, Inc., an agency that focuses on child abuse prevention, parenting education and family strengthening. Carlton Fields, along with client First Union, serves as a major sponsor of a fundraiser luncheon showcasing the Child Abuse Council and highlighting the Fathers Resource Center, whose mission is to make available to any father of young children the resources, support information and education that will enable him to develop a positive and nurturing relationship with his children.The Tallahassee office has adopted ECHO (Emergency Community Help Organization) family services program. Having established a legacy of sheltering the homeless, feeding the hungry and finding jobs for the unemployed, the Tallahassee office’s employees have held several furniture and household good drives for echo’s temporary housing facility, Bethany Family Apartments, whose goal is to keep homeless families intact while they work to rebuild their lives by participating in ECHO’s job training program.The Miami office, in collaboration with other organizations, has adopted Welfare to Work, a program designed to provide the occupational skills training necessary for a long, successful career in a law firm environment. Through college classes, law firm internships, and mentoring, candidates are prepared for their desired positions and receive continual support for their first year in the field.The West Palm Beach office has adopted New Hope Charities and will participate in funding projects to assist disadvantaged families in the Belle Glade-Pahokee area of Florida.The St. Petersburg office adopted Resurrection House, Inc., a non-profit, charitable organization that provides interim housing for families in need. Over the course of the past year, the St. Petersburg office has provided pro bono legal services to or for the benefit of Resurrection House; held a Career Clothing Drive, where a significant amount of career clothing was donated to residents of Resurrection House; provided typing and word processing instruction for residents of Resurrection House; held a “Painting Party” to refurbish the premises of Resurrection House; and contributed economically to the benefit of Resurrection House.The Crisis Nursery, which provides temporary day care to abused and at-risk children, has been adopted by the Orlando office that was primary sponsor of the 2001 “Fun Day” at Great Oaks Village. Carlton Fields lawyers spent the day leading in games and sharing refreshments with disadvantaged and abused youth.last_img read more

Houlton knocks off GSA boys’ basketball team in Class C North title game

first_img Mike MandellMike Mandell is the sports editor at The Ellsworth American and Mount Desert Islander. He began working for The American in August 2016. You can reach him via email at [email protected] Bio Latest Posts BANGOR — It’s over.After three straight Gold Ball wins and countless nights of dominating opponents on the Cross Insurance Center floor, the George Stevens Academy boys’ basketball team’s run of mid-February dominance has come to an end. GSA’s latest opponent, the Houlton Shiretowners, proved worthy of dethroning the back-to-back-to-back regional and state champions with an impressive performance from start to finish.Houlton defeated GSA 54-34 in the Northern Maine championship game Saturday to draw the Eagles’ reign as the unquestioned kings of Class C North boys’ basketball to a close. The Shiretowners overcame a sluggish start to the game with an efficient shooting performance and relentless defense to gain separation from GSA, which will end the season without a state title for the first time in four years.“It just wasn’t our night,” GSA head coach Dwayne Carter said. “I’m a little disappointed we didn’t play our best game tonight, but that happens.”This is placeholder textThis is placeholder textIsaac Wardwell gave GSA a two-possession lead to start to the game with a pair of baskets in the first three and a half minutes, during which the Eagles kept No. 4 Houlton (18-4) scoreless. Yet things changed quickly past the halfway mark in the first quarter when Nolan Porter hit back-to-back 3-pointers for the Shiretowners to spark an 11-0 Houlton run.Houlton then followed a Tanner Ashley 3-pointer with a score of its own to end the first quarter, and the Shiretowners continued their momentum into the second with four of the period’s first five baskets. Third-ranked GSA (18-4) kept Houlton in check offensively for the rest of the half, but the Eagles themselves mustered just five points during that span and trailed 25-15 at the break.GSA’s Percy Zentz defends against Houlton’s Cameron Callnan during the second half of the Class C North boys’ basketball championship game Feb. 23 at the Cross Insurance Center in Bangor. Zentz was part of a GSA senior class that boasted an 82-6 record over four years. ELLSWORTH AMERICAN PHOTO BY MIKE MANDELL“They put a lot of ball pressure on, and they made every pass tough,” Carter said of Houlton’s suffocating defense. “We tried a bunch of different sets to try and get going, but we just could never get into a flow.”After GSA scored the first basket of the second half, senior Reece Dannenberg responded to four Houlton points with a 3-pointer to cut the deficit to 29-20. Yet the Shiretowners scored the next nine points and took a 40-24 lead into the fourth quarter when Caleb Solomon made a layup at the buzzer.GSA cut the deficit to 46-33 after Houlton stretched its lead to 20 points early in the fourth quarter, but that was as close as it would get. The Eagles’ only points the rest of the way came on a Percy Zentz free throw as the Shiretowners walked off the floor with a Class C North title.Wardwell led GSA with 14 points. Dannenberg (five points), Michael Moon (four points), Tanner Ashley (three), Zentz (three), Caden Mattson (two), Andrew Szwez (two) and Eric Mote (one) also scored for the Eagles.Carter said Houlton’s string of 11 straight points made a comeback difficult for GSA early in the game. Although there were still more than three quarters to play at that point, Houlton’s shot-making and tough defense made it hard for the Eagles to keep pace with the Shiretowners.“We got off to a good start, but then we missed our assignments and let Porter get open twice,” Carter said. “Once they got rolling, that was it.”Both Carter and Houlton head coach Tim Brewer felt confident about how their teams matched up against one another entering the contest. Yet the Shiretowners, who got 18 points from Keegan Gentle and 14 from Porter, got the better of GSA in the matchup battle as they were too much on offense and limited the reigning champs’ scoring output to roughly half their season average on defense.“Coming into the game, I actually thought we matched up well with them on the defensive end,” Brewer said. “I didn’t think they matched up with us on the offensive end as far as their defense; I didn’t think they had anyone who could guard Keegan.”Houlton will return to the Cross Center to face Class C South champion and No. 1 seed Winthrop (20-1) for the state title at 8:50 p.m. Saturday, March 2. The Shiretowners will be seeking their third state title after winning Gold Balls in 2004 and 2014.Although GSA’s string of regional and state titles is no more, the Eagles still proved they could compete with the best in returning to another Northern Maine championship game. With Szwez, Mattson and Moon back next year, Carter’s team will have title ambitions once again.“People didn’t expect us to get this far, but I knew we could,” Carter said. “It didn’t end the way we wanted it to, but it is what is.” MPA approves golf, XC, field hockey, soccer; football, volleyball moved to spring – September 10, 2020center_img Ellsworth runners compete in virtual Boston Marathon – September 16, 2020 Hospice volunteers help families navigate grief and find hope – September 12, 2020 Latest posts by Mike Mandell (see all)last_img read more

National squads off to winning start at GTT National Indoor Hockey Championships

first_imgTHE annual GTT National Indoor Hockey Championships got off to a fast start on Monday, as the national ladies made their debut against SIDM, a combination of Hikers and Saints HC, at the Cliff Anderson Sports Hall.The new surface at the venue was being tested for the first time in competition and some players struggled to keep pace with the speed of the ball. The national ladies who have been benefiting from regular training at the venue seemed naturally the most comfortable as they dominated the possession, stringing together several passes in each build-up en route to a comfortable 11-0 victory.Marisha Fernandes and Trisha Woodroffe proved an impenetrable defence for the nationals as both demonstrated composure and generated several effective attacks from the back. Striker Kerensa Fernandes was top-scorer of the match with a hat-trick while Woodroffe, Marzana Fiedtkou and Maria Munroe each had doubles. Juniors Aliyah Gordon and Minsodia Culpepper completed the score sheet with one apiece.Pizza Hut GCC began their 2017 quest to retain the title in similar dominant fashion, as Sonia Jardine and Carina Moller both scored hat-tricks in their 8-1 beating of Old Fort Shooting Stars. Bushani Kaladeen was the noticeable standout for Old Fort although she only managed one goal for her team through a counterattack in the 5th minute. Captain Tiffany Solomon and Sandy Roopnarine scored the other two goals for GCC.The men’s first division competition produced a thrilling battle between Old Fort Titans and Bounty GCC as the two fought to a 5-5 stalemate in the end. Old Fort led from the start, going up by two field goals from Jael Gaskin in the first twelve minutes.GCC’s Alan Fernandes replied two minutes later but Akeem Hope restored Old Fort’s two-goal cushion in the fifteenth minute. GCC midfielder Orland Semple, returning from a long hiatus from the game, managed to draw his team within one for the second time just before the half which arrived with Old Fort enjoying a 3-2 lead.The game seemed surely beyond GCC five minutes into the second half as Old Fort hammered home two goals through Ascofu Simon and John Abrams to give Old Fort a 5-2 lead. GCC, however, launched an all-out attacking assault on Old Fort and found gaps in their earlier solid defence.The changed tactic by GCC produced the opportunities they needed as Dwayne Scott, Mark Sargeant and Peter DeGroot each found the back of the net with DeGroot’s equaliser coming in the penultimate minute of the match. The 5-5 draw leaves both teams in strong contention for the title that has eluded them for three years.The National Blacks completely dominated the Pepsi Hikers in their men’s first division duel finishing with a 12-0 score line while the National Greens gave Saints HC a 9-1 drubbing. The Old Fort Warriors pulled off a 5-1 victory over the Hikers in the lone second division matchup of the evening while the GCC Vintage enjoyed a 10-5 victory over Old Fort Goal-getters.Matches continue throughout the week from 17:00hrs with the finals being contested on Saturday. Men’s national selections, the BLACKs and the GREENs will play an exhibition match against each other right before the final presentation.last_img read more

ESI Gambling Report: Who’s doing what in 2018?

first_imgWith news rather slow as the esports industry gets back into the swing of things it’s time once again to put our good friends, the bookmakers, under the microscope and gauge who’s starting 2018 with a bang. We’re also having a look at who is set to do well in the new year and, as per usual, who is lagging behind. Start as you mean to go onBet365Without doubt, Bet365 continues to lead the way as we head into the new year. The bookmaker simply has the widest array of markets on the broadest range of tournaments.The Stoke based operator has odds on each of the League of Legends regions as well as the Demacia Cup, with specials for the upcoming Dota 2 Captain’s Draft tournament as well as outright and match betting. There’s also odds on the AfreecaTV PUBG League, Overwatch League, Starcraft II and some Rocket League and Heroes of the Storm for good measure. The team over at 365 continue to price tournaments that others don’t touch –  and the specials on Dota are continued example of the depth available within esports. It’ll be interesting to see if in 2018 other operators cotton on and expand their respective offerings. BetwayThe Ninjas in Pyjamas sponsor is not in shabby form as we approach what could be the biggest year yet for esports betting. Although they’re not quite on the level of 365 with a few titles missing and without specials, there’s still a broad range of offers available for the esports punter.Credit where credit’s due, Betway most definitely lead the way in promotional offers for their esports fans. There’s often enhanced multiples, money back offers should your team fail to win and plenty more. Plus the social media and content around Betway is second to none, as always. It’s great to have a regulated, well respected bookmaker operating in the space and investing as much as the Betway team in event and team sponsorship. Although there’s always somewhat of a stigma around gambling in an industry where there are likely to be a lot of minors, Betway did a fantastic job in 2017 of pleasing the esports audience and there’s no reason that it won’t continue in the coming year. Edging ever closerUnikrnUnikrn is a fairly odd bookmaker when you take what it is on the surface. Rahul Sood, the CEO, is a man with a fantastic vision and  it’s all set to come together under the Unikrn umbrella. There’s plans for dominance of the esports space with the crypto token UnikoinGold. Token betting should be allowed later this quarter and the company plans to obtain more gambling licenses across the world. Asian expansion and growth is also evidently a priority and opportunity so it’ll certainly be interesting to see the progress the company makes this year.The team continuously suggest there’s “big announcements” and “great developments” to be revealed this year and the company’s progress will likely depend on the crypto token and the uptake of the aforementioned new features. The website remains aesthetically pleasing and although it’s not quite up there with the 365’s – there’s enough to keep most esports fans happy. It’s definitely worth keeping an eye on Mr Sood & co this year – with a full editorial team, Berlin office and several other investments this could be a big year for the esports dedicated operator. GG.BetAlthough I am personally not the biggest fan of the GG.Bet layout, there’s still a whole lot of selection for punters. There’s now integration of live streams although it can be a little untidy. As far as I can remember, when the bookmaker launched it had very little by way of anything outside esports. Now it features traditional casino games and slots courtesy of some of the industry’s biggest suppliers such as Microgaming, Play’N’Go, Betsoft, Evoplay and Yggdrasil. There seems to be consistent activity there, too, with the “Current Winners” tab consistently refreshing with new winners. There’s even an instant game called “Courier Sweeper” which adds an esports twang to a casino title. Whereas Betway has positioned itself content wise as more of a Counter-Strike bookmaker – with Rob, their head of social media knowing a whole lot about the title, GG.Bet has taken a different approach. On the news tab there’s pretty rarely a story about anything other than Dota 2, which may be down to the popularity of the site in the CIS region. If I were a betting man, I would say that GG.Bet takes a whole more on Dota than Counter-Strike.It’ll be interesting to see the GG.Bet strategy this year. Whilst 2017 was a busy year for the company, appearing out of seemingly nowhere and becoming sponsors of several teams it’ll be interesting to see way the company goes about its business this year. PinnacleOver at Pinnacle there’s little doubt that the bookmaker still prides itself on what it offers, and its heritage in the esports space. The Curacao licensed operator was arguably one of the first regulated bookmakers to offer esports odds and continues to rack up  number of wagers. Although lack of markets is a constant gripe with the Pinnacle folk, that’s the way the business operates. The company prides itself on the best margins and lack of account limits for winners which is the unique selling point over many other bookmakers. When we’ve compared the odds previously, it’s often the case that Pinnacle slightly edge out other operators when it comes to odds on the favourite in an esports match up but fall short on the outsider. There’s still a range of titles to bet on, but nowhere near the amount of markets often seen on other sites. With the company’s revitalised esports hub this year – we’re looking forward to seeing the approach from Pinnacle. It’s evident that the company is not the abundantly clear market leader that it once arguably was in esports anymore so we’ll have to see if or how the approach has changed. We won’t be seeing any huge sponsorship details out of Pinnacle anytime soon, but if the esports hub produces nuanced, educational betting content similar to that of their main site then it could continue to find its place in the heart of many esports bettors. Who knows if they’ll have a dabble? Some of the biggest names, at least in the UK’s gambling world continue to shun esports or not really consider it at this time. There’s still debate around dedicated esports bookmakers, separate portal or just integrated book and to an outsider looking on – it’s impossible to tell whose approach is working best.We would just like to reserve this section for a special mention for Coral who continue to offer nothing. Ladbrokes once upon a time had esports odds, but following the merger with Coral no longer has any such odds. Maybe it’s just the Coral effect.An additional shout out goes to Betfred who actually has an esports section in the sportsbook. When you click it though, nothing happens. Finally, big kudos to PaddyPower. The operator does actually offer some odds but out of nowhere has plucked the classic “e-Sports” spelling. I mean, there’s a lot of guilty culprits here with eSports. Some even with E-Sports. But e-Sports? Come on now, let’s not be having that.last_img read more
