Bengals ReSign Marvin Lewis Through 2014

Marvin Lewis has as many lives as, well, a Bengal. A Cincinnati Bengal, that is.The coach that has endured a stingy ownership, myriad player arrests, questionable player development and losing. . . . not only remains standing, but has received a two-year contract extension through 2014.This is testament to the value of not giving up on a coach too soon. Lewis looked to be a goner more than once as players showed up on police blotters (not that it was his fault) fairly consistently and the team struggled to find a rhythm in winning. Instead of running him, the Bengals were patient, and Cincinnati emerged as a strong playoff team last year.The last time Lewis’ contract was running,  both sides seemed content to separate. They did not, and the rewards have been grand for the Bengals.Lewis is the franchise’s most successful coach since Sam Wyche, and has led the team to two AFC North titles in the past three years.As CBSSports.com reported that Lewis said negotiating the extension is “a complicated thing” and that he and owner Mike Brown are “comfortable together.”“Coming off a playoff finish last year, with a solid coaching staff and good young players, continuity at the top gives us our best chance to do well,” Bengals owner Mike Brown said in a statement. “We are excited about the team’s prospects and happy to have completed this process with Marvin before the 2012 preseason schedule begins.”Lewis is in his 10th season in Cincinnati, the third-longest current tenure with one team behind Andy Reid in Philadelphia and Bill Belichick in New England.According to CBSSports.com, in 2010, Lewis was up front that he was possibly going to explore other options, and it took something of a sales job to keep him. With the growth and development of the team since then, all the young pieces and the playoff appearance last year, the backdrop was much different now. The team has also beefed up its scouting staff and infrastructure since 2010, which were keys for the head coach. read more

A New Kind of Quantum Pump

first_img“We hope to apply quantum pumping to quantum computing architecture,” Ari Mizel, a professor at Penn State tells PhysOrg.com. In a world where scientists are striving to build quantum computing mechanisms and processes, various blueprints are on the table. And one of the integral parts of any quantum computing scheme is entanglement. Along with his student Sungjun Kim at Penn State and his postdoctoral researcher Kunal Das, now an assistant professor at Fordham University, Mizel proposes a quantum pumping method of delivering entangled electron pairs for use in quantum computing. A method that provides electron pairs and eliminates the background noise associated with single electron transport. Their findings are published in a Letter titled “Controlled Flow of Spin-Entangled Electrons via Adiabatic Quantum Pumping,” in Physical Review Letters.“Quantum pumping,” explains Mizel, “is a lot like swallowing. Electrons are in a channel, and as the walls deform periodically, it pushes stuff down.” Quantum pumping itself is not brand new, although the idea is a relatively recent development. Different experimental groups have been working with quantum pumping and use it to push charge or individual electrons with spin. What is different about the model of Kim, Das, and Mizel is that it would work by gathering paired electrons only, rather than “grabbing” single electrons and pumping them as well. Mizel’s team proposes a quantum pumping method that eliminates the transport of these single electrons that can provide background noise and increase decoherence.“We worked out a way to grab a couple of carriers at a time by changing interactions between the carriers,” says Mizel. The channels that hold the electrons are contorted, and the oscillations force the electron pairs through, carrying entanglement. Mizel explains, “The energy of individual electrons is not changed by the contortions. There is a counterbalance, so the individual electrons don’t feel the change. The electron pairs, though, feel it and get mushed closer together. Then the oscillations force them down and through.”This method would make it easier to eliminate non-entangled electrons. Right now, the background noise they create either has to be accounted for, or scientists attempt to catch and remove individual electrons. With this method devised by Mizel, Kim and Das, there would be no need to try to remove individual electrons; the carriers would just leave them behind, creating better entanglement. “There would be a stream of pairs, an individual electron will only feel contortion if it’s in proximity to a second electron. Then the carriers would be pushed down in groups.”Mizel admits that right now, this idea is in the theoretical stage. “We try to talk to people at conferences, and we’re familiar with who’s been doing quantum pumping in the past. Hopefully we can get some interest in this.” And it shouldn’t be that difficult. While Mizel concedes that this method of quantum pumping would be challenging to instigate, he also points out that it is not far beyond current scientific capabilities. “This doesn’t require any bold, brand new technology,” he insists. “It’s not far outside the possibilities. It would be interesting to see what could be achieved by this method.”Citation: Kunal K.

Google enhances Wear OS design adds a Google Assistant feed and much

first_imgLast week, Google announced that they have made some enhancements in the Wear OS design to provide users a quicker access to information and notifications, proactive help from Google Assistant, and smarter health coaching. Following are some of the improvements they have added to make the user experience better. Notifications on a single scrollable pane To check your notifications at once, you simply need to swipe up. A major improvement is, all notifications are displayed on a single scrollable pane as opposed to having them fill the entire screen one by one. If you receive a message and want to quickly reply to it, you can use a built-in smart reply. Shortcuts and handy features To view shortcuts and handy features you simply have to swipe down. The Quick Settings pane is slightly revamped with two buttons, one for finding your phone and another for Google Pay. Smart suggestions from your Google Assistant Users will now receive a proactive and personalized feed of information from Google Assistant. To view this feed you need to swipe right. Based on your plan, it will give you predictive information about your day. You can plan your day, get answers, and manage your tasks with the help of Google Assistant. To invoke Google Assistant, long press the power button or say “Hey Google”. Start and track your workout goals Recently Google released Google Fit with two new activity goals, namely, Heart Points and Move Minutes. These are based on the activity recommendations by American Heart Association and the World Health Organization, which are shown to have health benefits for your heart and mind. You can swipe left to start and track your workout goals. To stay motivated you can also download or stream your favourite music. The smartwatches are available in various brands such as, Fossil, Huawei, Emporio Armani, and Casio, leaving behind the old boring design. To read the official announcement, head over to the blog posted by Google.
