South Carolina star running back Marcus Lattimore suffered one of the most gruesome injuries seen on a football field Saturday when he was hit by Tennessee’s Eric Gordon and his leg flapped in the wind and onto the turf, as if it was snapped in half below his right knee.”I don’t know that I’ve ever seen anything like that,” Gamecocks coach Steve Spurrier said.The official injury announced Sunday is awful for anyone, but potentially career-ending for a running back like Latitmore, who was sure to be an early-round NFL draft pick: a dislocated knee.Hardly ever are players from both teams impacted by a player’s injury, but both teams were emotional by what they witnessed in the second quarter of South Carolina’s 38-35 victory.Lattimore was running through the left side when he was struck around the knees by Gordon, Lattimore’s right leg whipping around and slamming against the turf. South Carolina trainers immediately rushed to his side, keeping Lattimore flat on his back as the junior attempted to sit up and see the injury.“I just tried to tell him to stay mentally strong,” said receiver Ace Sanders, whose eyes teared up when discussing Lattimore. “I saw the look in in his eyes when he was on the ground and he was really heartbroken.”Coming into the game, Spurrier had said Lattimore was 100 percent and would carry the load for the Gamecocks. Lattimore rushed for 65 yards, including a breakaway 28-yard TD run, in the first half against Tennessee after coming in with 597 yards rushing and 10 touchdowns this season.He became an instant star as a freshman, rushing for 1,149 yards and 17 touchdowns. Lattimore was on his way to eclipsing those numbers as a sophomore until the injury at Mississippi State. He holds South Carolina records with 41 overall touchdowns and 38 on the ground.Last year Lattimore had surgery to repair ligaments and cartilage in his left knee and needed six months of rehabilitation and recovery before he was cleared to return to action.This injury, however, might be too devastating for Lattimore to overcome.
Bournemouth boss Eddie Howe is happy with his team’s response after they beat Blackburn 3-2 in the Carabao Cup on Tuesday night.Eddie Howe made nine changes to his starting XI on Tuesday, following his team’s 4-0 drubbing at Burnley. And the Cherries responded well with a victory thanks to a late goal from Callum Wilson.“We desperately needed a performance tonight after the Burnley game, of course, we needed a reaction,” he said.“You feel better but still Burnley is not far away in my thoughts. That’s just how I am and until we put that right in the Premier League that will still be with me.”Eddie Howe pleased with attacking poise, but feels Wilson was too honest Stuart Heath – August 25, 2019 A.F.C Bournemouth manager Eddie Howe felt as though his striker Callum Wilson was too honest against Manchester City and may have won a penalty,…He added: “I’d say (tonight) 90 percent was positive. I thought we played some good football and then suddenly bang, bang, we concede two goals.“Only we could do that to ourselves. We shot ourselves in the foot twice, made some bad decisions and then it’s in the balance.“And then you’re thinking the lottery of a penalty shoot-out was going to be the outcome of the game and it should never have been in that position.“But credit the players again because we get ourselves in these positions and sometimes we get out of that hole we’re in because of our attitude, because of our spirit.”
Posted: October 16, 2018 AP Stocks surge on earnings and economic data; Dow climbs 500 October 16, 2018 NEW YORK (AP) — World stock markets are rallying Tuesday, and U.S. stocks are on track for their second-largest gain in 2018 following strong earnings reports from major U.S. companies in finance and health care. Technology companies are also rising after their recent slump. The Dow Jones Industrial Average rose as much as 502 points.Even with the big gains, major indexes are still broadly lower for the month following a two-day rout last week that erased nearly 1,400 points from the Dow.Investors were encouraged by some good news on the economy. The Federal Reserve said output by U.S. factories, mines and utilities climbed in September despite the effects of Hurricane Florence, and the Labor Department said U.S. employers posted the most jobs in two decades in August while hiring continued to increase.KEEPING SCORE: The S&P 500 index jumped 54 points, or 2 percent, to 2,805 as of 2:45 p.m. Eastern time. The Dow gained 494 points, or 2 percent, to 25,745.The Nasdaq composite climbed 192 points, or 2.6 percent, to 7,623 as technology companies reversed some of their outsize losses from the last few days. The Russell 2000 index of smaller-company stocks rose 39 points, or 2.6 percent, to 1,592.Earnings for U.S. companies climbed about 20 percent in each of the first two quarters of 2018 as economic growth picked up and corporate taxes were slashed. Analysts expect similar results in the current period.Stocks have gyrated over the last three days following a six-day losing streak that included some of their biggest declines of the year. The S&P 500 fell 6.9 percent from its record high on Sept. 20 to its recent low on Thursday. It remains 4.3 percent below that record level.HEALTHY…: UnitedHealth, the largest U.S. health insurer and provider of privately-run Medicare Advantage plans, once again topped Wall Street forecasts and raised its projections for the year.

A research group in the UK has crafted a source of single photons – photons emitted one by one – with a convenience and ease of use they liken to “plug and play” computer hardware devices. This is a key step forward in single-photon production, which is essential to successful, secure quantum communication, the transmission of data using individual photons to carry bits of information. Quantum sensor breakthrough using naturally occurring vibrations in artificial atoms Citation: ‘Plug and Play’ Source of Single Photons (2007, March 15) retrieved 18 August 2019 from https://phys.org/news/2007-03-source-photons.html A sketch of the single-photon source with the integrated optical-fiber bundle. The quantum-dot wafer is mounted onto the sample holder (right inset) with the fiber bundle attached directly to its top surface. The “WDM” is the beamsplitter. Explore further The device’s plug-and-play quality lies in its novel design. A bundle of optical fibers is coupled with – or “plugged into,” so to speak – a wafer patterned with quantum dots. Quantum dots are tiny atom clusters of a semiconducting material, such as silicon, that contain as few as a hundred atoms and play a key role in many single-photon-production schemes. In this case, they emit photons when excited with laser light.“Pairing the optical fiber bundle and the quantum-dot wafer presents a way to implement real quantum communication that other single-photon sources do not have,” said lead researcher Xuilai Xu, a scientist at Hitachi Europe Ltd. in Cambridge, to PhysOrg.com. Xu and his colleagues at Hitachi performed the study in collaboration with researchers at the University of Cambridge.The wafer is mounted onto a sample holder, immersed in liquid helium, and then excited with a laser. During this process, the dots’ atoms absorb the laser photons and jump to a higher energy state, but almost instantly re-emit the photons and return to a lower-energy state. The emitted photons travel through the fiber bundle to a beamsplitter, which sends the emitted photons out one fiber and the residual laser photons out another.Accurately determining if the source produced single photons was a tricky task. Xu and his colleagues had to use several devices to analyze the emitted photon signal. These included a spectrometer, which measured the intensity of the light, and two single-photon-counting “photodiodes,” semiconductor devices used to detect light. They also applied a filter to subtract out background photons, ensuring that the photons emitted from the quantum dots were not mixed with photons emitted from the wafer’s “wetting layer,” a thin layer of residue formed on the surface of the dots as the wafer was created.Analysis of the data produced by the measurement and detection devices showed that the photons tended not to be emitted in pairs. And, according to the researchers’ calculations, the addition of the filter, when it was placed at the proper angle, greatly reduced the probability that photon counters would detect more than one photon at once – specifically, the likelihood of this was reduced 100-fold.“This indicates a nearly ideal single-photon source,” said Xu.To test the stability of their design, the group measured the photons emitted from 27 quantum dots, traveling through different optical fibers in the bundle, over a 24-day period. The results showed the photon source to be stable over a timescale of weeks, with no evidence that a considerably longer period would result in degradation.Citation: Xiulai Xu, Ian Toft, Richard T.
