US womens national soccer team down to nittygritty on road to 2011

With 44 days remaining until the start of the FIFA Women’s World Cup in Germany, the U.S. women’s national soccer team’s preparations have reached their peak. The U.S. capped off a week of training at Ohio State’s Jesse Owens Memorial Stadium with a 2-0 international friendly match win against Japan on Saturday at Crew Stadium. Two tuneup matches remain for the U.S. squad before its first World Cup match on June 28 against North Korea in Dresden, Germany. The U.S. will face off against Japan again Wednesday in Cary, N.C., before having its traditional send-off match against Mexico on June 5 at Red Bull Arena in Harrison, N.J. American goalkeeper Hope Solo said prep work for this summer’s tournament extends beyond the soccer field. “We have two more games to prepare for, and we have to crack down on everything,” Solo said. “There is no time to let anything go unnoticed. We are watching video; we are in meetings; we are cracking down on everything so that we can win this tournament.” Defender Becky Sauerbrunn agreed, adding that the team has focused on “smaller” details, such as set pieces, corner kicks and defensive formations. “We’re really getting down to nitty-gritty,” Sauerbrunn said. “Right now, it’s the small details that are gonna make the biggest difference.” Forward Abby Wambach said the U.S. might rearrange its lineup and strategies for its second match against Japan so potential World Cup opponents can’t scout the team as easily. “We don’t want to do the exact same thing,” Wambach said. “We want to throw a little wrinkle into our game here or there. Look to see some different things and maybe even some different personnel (against Japan).” Wambach, who scored her 118th career international goal Saturday, said she hopes the attention to minute details will allow the team to emulate the success of the U.S. women’s national team that won the World Cup in 1999. But make no mistake — Wambach wants the legacy of the 2011 national team to be unique. “We want to define this team,” Wambach said. “Obviously, everybody knows the (1999) World Cup-winning team. We want to prove ourselves. We want to show the world that this team is, in fact, great still and we still are capable of winning world championships at the World Cup level.” Wambach also said she expects the Americans to compete at a high level once the tournament begins. “I’m pretty confident that, no matter what goes on from now until (the World Cup), we’re gonna show up,” she said. U.S. coach Pia Sundhage said she is certain the team will be ready for its first World Cup match. “We need a couple more days together,” Sundhage said. “When the game against North Korea comes on (June) 28, we’ll be ready.” The U.S.’s next match against Japan is scheduled to kick off at 7 p.m. Wednesday. read more

Pepe Reina eyes improvements at AC Milan

first_imgAC Milan new signing Pepe Reina is “looking forward” to integrating into the club and hopes that they will be able to build on their results from last seasonThe veteran goalkeeper joined from Serie A rivals Napoli on a free transfer earlier this month and has travelled with his new teammates to America, where they will be participating in the International Champions Cup.Reina had a successful spell at Napoli, whom he joined in a loan deal from Liverpool in 2013 and won the Coppa Italia that season, before rejoining the Light Blues on a permanent deal in the summer of 2015 from Bayern Munich.And three years later with 153 appearances under his belt, Reina chose to end his stay at Napoli in favour of joining Milan after coming so close to winning the Serie A last season.The 35-year-old told the club website: “I’m very happy. I’m really looking forward to adapting to the team quickly and contribute. I want to improve and help the team to become even stronger and overcome what was achieved last year.Reina’s experience will undoubtedly prove to be an invaluable asset for Milan alongside their teenage goalkeeper Gianluigi Donnarumma and his 28-year-old brother Antonio Donnarumma.Maurizio Sarri, JuventusMaurizio Sarri satisfied despite Juventus’ draw at Fiorentina Andrew Smyth – September 14, 2019 Maurizio Sarri was satisfied with Juventus’ performance on Saturday afternoon after finishing a tough game at Fiorentina 0-0.“I already had a good relationship with both before (the Donnarummas). It will be a fun year. All three of us feel we are number one. We are in a very important Club: we will all give our best, then coach Gattuso will decide,” he said.Reina could make his debut for Milan on Thursday in their first game of their US tour against Manchester United.Pepe Reina arrives at Milanello just in time to join the #DevilsInUSA! [email protected] per la prima volta a Milanello, pronto a volare con noi negli Stati Uniti! ?? ¡Bienvenido al equipo, Pepe! ?⚫#weareacmilan pic.twitter.com/SPozJoe76b— AC Milan (@acmilan) July 22, 2018last_img read more

Cristiano Ronaldo will  be on bench tomorrow– Juventus coach reveals

first_imgJuventus face Atalanta on Boxing Day in Bergamo for the first time after 47 years.Juventus coach Massimiliano Allegri has revealed that Portuguese star International Cristiano Ronaldo will not be featured in the clash on Boxing Day but will watch the match from the bench.Speaking to Sky Sport as quoted by Juventus official website on Christmas Day, Allegri bared his thoughts on the upcoming match, saying:Serie A, Gian Piero GasperiniGasperini reveals why he rejected Inter Manuel R. Medina – September 14, 2019 Atalanta manager, Gian Piero Gasperini, has revealed why he rejected Internazionale Milan’s job proposal over the summer transfer window.“Cristiano Ronaldo will not play tomorrow. However, he is available and will be called up, so for the first time we will watch the game together from the bench! Joking aside, I’m very happy with what he’s doing. I was reading some statistics and this year is his best start to a debut season, but must have him still in top shape come March, when there will be the Champions League and he will have to be decisive, as he has always been.”“The gifts I would like to receive are at the end of the season. We will try to collect one present on January 16, the Italian Super Cup. Then we will have the opportunity to pick up more presents later, but we will have to be playing well to make it happen for ourselves.”last_img read more

Physicists propose first method to control single quanta of energy

first_imgIn the proposed experiment, two energy reservoirs (S and D) made of trapped ions transport energy quanta to each other by coupling to the spins in a quantum magnet placed between them. Credit: Alejandro Bermudez and Tobias Schaetz, New Journal of Physics. CC-BY-3.0 (Phys.org)—Physicists have proposed what they believe to be the first method to control the transport of energy at the level of single energy quanta (which are mostly phonons). They show that it’s theoretically possible to control the flow of single energy quanta through a quantum magnet using lasers with carefully controlled frequencies and intensities.

DOI: 10.1088/1367-2630/18/8/083006 Citation: Physicists propose first method to control single quanta of energy (2016, August 29) retrieved 18 August 2019 from https://phys.org/news/2016-08-physicists-method-quanta-energy.html If implemented, the method could allow researchers to explore quantum energy transport phenomena that are expected to be completely different than what is observed in macroscopic energy transport. In general, understanding energy transport in small-scale devices could lead to the development of methods for reducing the energy dissipation in shrinking computer hardware (however, the researchers note that computer hardware differs from the particular setup proposed here).The scientists, Alejandro Bermudez, at the Institute of Fundamental Physics in Madrid, Spain, and Tobias Schaetz, at the Albert Ludwigs University of Freiburg and the Freiburg Institute for Advanced Studies, both in Freiburg, Germany, have published a paper on their proposed method in a recent issue of the New Journal of Physics. “We have identified a new quantum mechanism that would allow to control the transport of energy/heat at the level of single energy quanta,” Bermudez told Phys.org. “This mechanism can be considered as an analogue of Coulomb blockade in electronic nanodevices, and we have proposed to test it using experiments with crystals of self-assembled trapped atomic ions.”In the study, the scientists propose building an energy reservoir using trapped magnesium ions. By using a laser to heat and cool the ions, the ions can be made to absorb or release tiny amounts of energy, acting as tiny energy reservoirs. Then to transport the energy, the researchers propose placing a synthetic quantum magnet—which consists of a long line of magnetic spins that form a chain—between two energy reservoirs. When the reservoirs are coupled to the spins in the magnet, they can exchange energy with each other in the form of single phonons. In this way, quantum-scale energy transport occurs across the spin chain. The scientists explain that energy transport at the quantum level can be thought of as analogous to charge (electron) transport at the quantum level, which has already been well-documented. Just as single-electron transport is very different than bulk electron transport, quantum energy transport is expected to be very different than energy transport on a large scale. © 2016 Phys.org Long-distance transport of electron spins for spin-based logic devices One particular phenomenon associated with single-electron transport, which is not observed at larger scales, is called the Coulomb-blockade effect. In nanoscale electronic devices, electrons must gain a certain level of charging energy in order to tunnel across a barrier. When one electron manages to gain this energy and tunnel, it blocks the simultaneous tunneling of other electrons because additional electrons would require additional energy. The resulting blockade effect violates Ohm’s law of charge transport, and results in only one electron tunneling at a time.In the new study, the physicists theoretically demonstrated that an analogous Coulomb-blockade effect occurs with nanoscale heat transport, which again does not appear at larger scales. The scientists derived a quantum master equation for the transport of energy that shows that there is a “transport window” that defines the energy level needed for energy quanta to travel through a quantum magnet. Similar to the situation with electrons, energy transport is blockaded when the energy quanta do not have sufficient energy. This effect, which the researchers call the Ising blockade effect, violates Fourier’s law of heat conduction and results in the transport of only one energy quantum at a time.If the proposed experiment can be realized, the researchers expect to observe the Ising blockade effect along with many other interesting quantum effects in energy transport that so far have been restricted to electronic currents. At this stage, it’s difficult to tell what applications quantum energy transport may have.”If the same effect can be shown to be more general, and applicable to other physical setups, it may yield unexpected applications similar to single-electron electronics in Coulomb-blockaded devices,” Bermudez said.One of the biggest challenges to realizing the experiment will be to design a device that can directly measure such tiny amounts of heat energy.”We are considering exploring this type of physics in the laboratory of my coauthor, Professor Schätz, at the University of Freiburg,” Bermudez said. “Although the experimental requirements to implement the proposed scheme are stringent, Professor Schätz leads a world-class team of fantastic researchers with the required technology to face this challenge.” This document is subject to copyright.
