Mens hockey team lets potential sweep slip away

With a 2-1 lead after two periods, the Ohio State men’s ice hockey team (5-7-1, 2-5-1-1 CCHA) seemed poised to “sweep” a two-game series with the No. 14-ranked University of Alaska-Fairbanks (8-5-3, 5-4-3-2 CCHA) Saturday at Nationwide Arena. But the Buckeyes quickly lost control of the game and gave up four third-period goals, including three in the final 5:30 of play, as Alaska skated to a 5-2 win. “It was a good team effort tonight,” Alaska coach Dallas Ferguson said. “We were missing a couple of guys but we feel like we have good depth at our positions. The guys did what they had to do to be successful.” OSU senior forward John Albert gave OSU a 1-0 lead with his wrap-around goal just 2:16 into the first period. Freshman forward Alex Lippincott gave the Buckeyes a 2-0 lead in the second period, and OSU appeared to be in control of the game. Momentum quickly shifted to Alaska’s favor when OSU junior forward Danny Dries received a major penalty for hitting an Alaska player from behind. The Buckeyes had to play a man down for five minutes. Alaska scored on the power play, the start of a 5-0 run. After the goal, OSU senior defenseman Corey Toy had to sit two minutes for a slashing penalty, giving Alaska a 5-3 man advantage. OSU coach Mark Osiecki said the two penalties in the second period changed the game in Alaska’s favor. “The difference in the game was the five-minute major and the two-minute minor in the first 40 minutes,” he said. “The penalties killed us. We wasted so much energy killing the penalties that it wore on us the rest of the game.” Despite the disappointing loss, OSU did not leave the series empty-handed. In the first game of the series Friday, the teams skated to a 3-3 tie, and OSU won in a shootout. OSU trailed 3-2 into the final minute of the game, but with just 10 seconds remaining, Dries scored for the Buckeyes to force overtime. Neither team scored in the five-minute overtime period, so the teams went into a shootout. OSU goalie Cal Heeter stopped all three of Alaska’s shootout attempts as Dries scored for OSU, giving the Buckeyes a shootout victory, 1-0. The game is considered a tie in the NCAA standings, but the shootout win benefits OSU in the CCHA conference standings. The Buckeyes will now turn their attention to Michigan as OSU starts a two-game series with the Wolverines on Friday. Michigan is second in the CCHA, but Albert said OSU will be up to the challenge if the Buckeyes play as one unit. “We have to play as a team. We can’t play as individuals,” he said. “If we do that, I hope we can get two wins next weekend.” read more

Season preview Boom or bust for Columbus Blue Jackets in 201718

Credit: Courtesy of TNSAnticipation has reached an apex and optimism is high, but this isn’t unknown territory. The Columbus Blue Jackets had a franchise record 50-24-8 (108 points) and made the Stanley Cup Playoffs for only the third time franchise history last season. For all the firsts the 2016-17 season held, the Blue Jackets have been in this situation before, with thoughts of the previous season blasting the team toward a chain of success. But that has never happened. The team has never won a playoff series or even made back-to-back playoff appearances. The beginning of an 82-game regular-season journey to those goals begins Friday.The Blue Jackets open the 2017-18 NHL season Friday night at Nationwide Arena against the New York Islanders with hopes of a breakthrough and expectations to compete with the league’s elite teams, such as division rivals Washington and back-to-back Stanley Cup champion Pittsburgh.Before the puck drops at 7 p.m. Friday, here’s what to look for ahead of the 2017-18 season.Storylines:Artemi Panarin: How does a front office address goal-scoring concerns on its offense? By trading for one of the top power-play forwards.The Blue Jackets acquired Blackhawks winger Artemi Panarin in a four-player deal, which included Brandon Saad and two draft picks. Panarin played on Chicago’s second line the last two seasons with superstar Patrick Kane and has been credited with a couple of Kane’s best career years, while accumulating 60 goals, 91 assists, 151 points in two seasons himself.He will likely join center Alexander Wennberg and right wing Cam Atkinson on the first line adding elite passing ability, a right-handed shot from the left wing and one of the most feared one-timers in the NHL.Foligno at center: After a down year in 2015, Foligno returned to normalcy in 2016, proving his captain status to Tortorella, who doubted the 29-year-old in his first season in Columbus. Now in 2017, Foligno will be asked to put up a similar 26-25-51 line at the center position for the first time in his 10-year NHL career.Foligno unexpectedly made the Ottawa Senators roster in 2007 and was placed at left wing because of a loaded center position. Now the captain is moving back to his original spot due to an absence of ready talent at the moment.Rookie Pierre Luc-Dubois, who was expected to fill the No. 3 center spot following the departure of center William Karlsson to Vegas in this summer’s expansion draft, will play left wing in a move to alleviate some growing pains the 2016 No. 3 overall pick might have in his first NHL season. Can Jackets have top-10 defense: With Bobrovsky between the pipes, the Blue Jackets will nearly always have a chance to win the game. He was 41-17-5 with a .931 save percentage and 2.06 goals allowed average last season, but it’s difficult to expect those numbers again from the league’s only active two-time Vezina winner without the continued emergence of a young defense.Zach Werenski, 20, and Seth Jones, 23, are two of the best young defensemen in the league and anchor the Jackets’ top defensive pair. Jack Johnson and David Savard will likely man the second pair again, but Gabriel Carlsson is probable to start on the third pair with Ryan Murray with Scott Harrington as the seventh man. Markus Nutivaara, who played in 66 games during his rookie season in 2016-17, will begin the season in Cleveland with the team’s American Hockey League affiliate following offseason hip surgery.Carlsson, 20, played in just two regular-season games last season before being thrown into the playoff series against Pittsburgh. Still qualified as a rookie, the 6-foot-5 Carlsson will become a fixture in Tortorella’s lineup if he can be a factor in the Jackets’ own zone.Josh Anderson, Boone Jenner injury: After missing all of training camp with a lengthy contract dispute as a restricted free agent, right winger Josh Anderson inked a three-year deal Tuesday, but will begin the season with Cleveland. He recorded 17-12-29 in last year’s rookie campaign.Left winger Boone Jenner will miss the season opener and likely longer than that as he is dealing with a back injury. Sonny Milano will likely start in place of Jenner Friday as Milano, a 2014 first-round pick, tries to play a full season in Columbus for the first time in his career.Schedule Outlook:The Blue Jackets being with a division opponent in the Islanders, then head on the road to face Chicago Saturday. Columbus’ first month has the potential for a fast start with seven of 12 games at home and only five of those 12 games are against playoff teams from last year.Forwards: Cam Atkinson, Oliver Bjorkstrand, Matt Calvert, Zac Dalpe, Brandon Dubinsky, Pierre-Luc Dubois, Nick Foligno, Markus Hannikainen, Boone Jenner*, Sonny Milano, Artemi Panarin, Lukas Sedlak, Alexander WennbergDefensemen: Gabriel Carlsson, Scott Harrington, Jack Johnson, Seth Jones, Ryan Murray, David Savard, Zach WerenskiGoaltenders: Sergei Bobrovsky, Joonas KorpisaloThe Lantern will post an article at the beginning of each week summing up all the Blue Jackets action and storylines that took place on the ice during the week. It will analyze the significance of the week’s action, a look ahead to the upcoming week and often include quotes from coaches and players. read more

Physicists design zerofriction quantum engine

first_img Journal information: Scientific Reports (Phys.org) —In real physical processes, some energy is always lost any time work is produced. The lost energy almost always occurs due to friction, especially in processes that involve mechanical motion. But in a new study, physicists have designed an engine that operates with zero friction while still generating power by taking advantage of some quantum shortcuts. Quantum engines must break down Explore further Scientists have devised a way to run a quantum cycle based on the use of quantum shortcuts to adiabaticity, where friction-like effects are quenched. Shown are the four steps of a quantum Otto cycle, where heat enters (exits) the working medium and those where work is performed by (done onto).

But for quantum technologies on the micro- and nano-scale, quantum fluctuations that are insignificant on large scales start to become prominent. As previous research as shown, the large quantum effects call for a complete reformulation of the thermodynamics laws.What a quantum version of thermodynamics might look like is not yet known, and neither are the limitations or possible advantages of the quantum devices that would be described by such laws. However, one intriguing question is whether it may be possible to build a reversible quantum engine—one in which the engine’s operation can be reversed without energy dissipation (an “adiabatic” process).In the new paper, the physicists have shown one example of a quantum engine that is “super-adiabatic.” That is, the engine uses quantum shortcuts to achieve a state that is usually achieved only by slow adiabatic processes. This engine can achieve a state that is fully frictionless; in other words, the engine reaches its maximum efficiency, while still generating some power.”Shortcuts allow us to ‘mimic’ what would be achieved by running a cycle quasi-statically, i.e., very slowly, while performing transformations at finite time,” coauthor Mauro Paternostro at Queen’s University in Belfast, UK, told Phys.org. “Now, consider for instance a compression or expansion stage of a cycle run using a piston. When doing it at finite time, i.e., non-zero velocity, friction might affect the performance of the transformation. Yet, by using a shortcut to adiabaticity, friction-like effects would get quenched, the cycle performance being the same as that of a quasistatic motor.”The work marks a step toward the key engineering goal in this context, which is to find the maximum efficiency allowed at the maximum possible power. As the scientists note, this pursuit is complicated by the existence of a trade-off between the running time of the super-adiabatic process and the corresponding amount of work dissipated.”This work is one of the first steps into the merging of quantum control and thermodynamics,” Paternostro said. “We have shown that it is possible to use techniques that, to date, have only been used for other goals (population transfer, for instance) for thermodynamic tasks and the engineering of efficient cycles.”Overall, the results suggest the possibility of a frictionless quantum engine operating at maximum efficiency, which has implications in designing micro- and nano-scale motors operating at the verge of the quantum scale. In the meantime, there are still several hurdles to overcome.”I think that the real challenge is the use of such techniques in interacting quantum many body systems, whose inherent complexity and rich phenomenology could be ‘tamed’ by the use of this sort of quantum control,” Paternostro said. “At the end of the day, thermodynamics is a theory of many particles, and its quantum formulation should be able to cope with many-body effects, whose control could hugely benefit from the implementation of schemes similar to the one proposed in our paper. We have new and exciting results, in this context, that will come up soon and that will hopefully have an impact in the community interested in many-body physics and quantum thermodynamics.” Citation: Physicists design zero-friction quantum engine (2014, September 16) retrieved 18 August 2019 from https://phys.org/news/2014-09-physicists-zero-friction-quantum.html More information: A. del Campo, et al. “More bang for your buck: Super-adiabatic quantum engines.” Scientific Reports.

TMC members protest against disinvestment in Rajya Sabha

first_imgNew Delhi: Trinamool Congress members in Rajya Sabha on Monday sought to disrupt proceedings of the House by entering the well and raising slogans to protest disinvestment of public sector companies. Some TMC members, including Derek O’Brien and Sukhendu Sekhar Roy, were also on their feet and repeatedly asked the Chair to permit them to raise the issue of disinvestment of state-run firms during the Zero Hour. Chairman M Venkaiah Naidu did not allow them to raise the issue, saying members should not resort to such measures to raise issues and that he would not succumb to pressures. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata Naidu, however told TMC members he would allow them to raise the matter only if there is time left. TMC members continued to raise slogans but the Chair said nothing of that sort would go on record. Some members of the ruling BJP too were seen responding to the sloganeering of TMC members. Just before the House adjourned for lunch, Naidu cautioned members not to enter the Well and use such measures to press for their demands. The last session of the Rajya Sabha, held before the general elections, had witnessed several adjournments due to protests by opposition parties. Also Read – Lightning kills 8, injures 16 in state However, the current Budget session has not witnessed any major protest by opposition parties. Members raise important issues of public interest during the Zero Hour after the Chair permits them to do so. Earlier, the issue of rejection of two bills by the President of India, which were sent to his office in 2017 by the Tamil Nadu government, to exclude the state from the National Eligibility-cum-Entrance Test (NEET) was raised. Arch rivals in Tamil Nadu — AIADMK and DMK — lodged their protest against the rejection of the bills. A Navaneethakrishnan (AIADMK) and Tiruchi Siva (DMK) lodged protests on behalf of their parties. DMK members also staged a walkout. In his Zero Hour mention, Rewati Raman Singh (SP) highlighted the situation in the country due to deficient rainfall. He said 18 states have been hit by deficient rains and it would badly affect paddy sowing.last_img read more
