When the Raiders play their last game at the Oakland Coliseum on Sunday, there will be lots of nostalgia.Decades of winning football, although at times that’s hard to remember. Three Super Bowl victories. The memories of Jim Otto, George Blanda, Gene Upshaw, Fred Biletnikoff, Ray Guy, Art Shell, Daryle Lamonica, Willie Brown and Ken Stabler. For those in the Bay Area who grew up on Raiders football, the team brought memories that have lasted a lifetime.But it’s been like a bad marriage. We …
Inter Milan striker Alexis Sanchez cuts ties with Man Utd palsby Paul Vegasa month agoSend to a friendShare the loveAlexis Sanchez has cut ties with his former Manchester United teammates.Sanchez has had a promising start to life at Inter Milan, where he’s on-loan, scoring twice on Saturday however he was sent off shortly after in their win over Sampdoria. Insiders at Manchester United have revealed Alexis Sanchez’s role in the changing room was rather minimal, and that is reflected with his lack of activity in the WhatsApp group.The source told The Sun: “It’s as if he was never here.”New Roma signing Chris Smalling is however said to be involved in the chat, while he is out on loan in Italy.

Title College Football Playoff (CFP) rankings as of Nov. 3. But back to football substance. I mentioned before how lots of teams, even if they don’t technically control their own destiny,7No team controls its own destiny, technically, since there are no guaranteed bids in the playoff. are favored to make the playoff if they win the rest of their games. Now that the model is (hopefully) doing a better job of mimicking the emphasis that human voters place on wins and losses, we can be more precise about that. Specifically, the model estimates that 14 teams have a 50 percent or greater likelihood of making the playoff conditional on winning out.The model figures that Michigan State, for instance, has an 86 percent chance of making the playoff if it wins out. Even the lowliest one-loss major conference team, North Carolina, which wasn’t ranked by the committee last week, is about even-money to make the playoff if it wins out. And undefeated Iowa (91 percent) and Oklahoma State (97 percent) are all but assured of making the playoff if they finish the year without a loss, even if the committee doesn’t have them in the top four tonight. Baylor 8-067234%32%12% Notre Dame 8-1569—30%7% Iowa 9-09132927%18%2% Texas A&M 6-3194923<1%<1%<1% And here’s a new summary table showing the playoff picture heading into tonight, when the playoff committee will release its new rankings at 7 p.m. Undefeated Baylor has moved slightly ahead of one-loss Notre Dame in our forecast, but otherwise the top six are unchanged. LSU 7-129814%15%4% Oklahoma 8-11514119%17%7% Last season’s first-ever College Football Playoff might have miscalibrated everyone’s sense of what it takes to make it to the final four. Six power conference champions or co-champions1Thanks to a dubious decision by the Big 12. — Alabama, Baylor, Florida State, Ohio State, Oregon and TCU — were undefeated or had one loss against reasonably good schedules. There’s plenty of room to critique how the committee went about leaving Baylor and TCU out, but there was no one inherently correct way to slot six fairly equally matched teams into four playoff positions.But a field as crowded and qualified as last year’s was atypical. Most of the time there are a couple of teams that are weak links: a three-loss conference champion here, a one-loss team that played an incredibly weak schedule there. A mess like last year’s isn’t impossible, obviously. But usually the knot will untangle itself through conference championships, rivalry games and upsets that knock teams out late in the season.So don’t despair, Michigan State fans. (Of which I’m one.) Yeah, you probably lost on a bad call last weekend. But you’re still highly likely to make the playoff if your team wins all of its remaining games, in which case you’ll have defeated Ohio State and (probably) Iowa in the Big Ten championship. Pretty much every one-loss team from a power conference is more likely than not to make the playoff if it wins out.And an undefeated power conference team like Oklahoma State shouldn’t fret, even if it is currently outside the committee’s top four. Some of the teams ranked in front of it are almost certain to lose — and even if they don’t, there’s a good chance Oklahoma State will leapfrog some one-loss teams if it keeps winning.Our subjective perceptions of the playoff picture aren’t the only thing that may be miscalibrated, though. The same could be said about the FiveThirtyEight College Football Playoff model. At least, that’s the conclusion we came to when we were conducting research for this article. Although the model seems to give basically reasonable answers, a couple of things left us scratching our heads when we examined it more deeply.For instance, it posited a conspicuously large gap between Iowa’s chance of winning the Big Ten championship (27 percent) and making the playoff (8 percent). Iowa is undefeated, and while it’s possible they could win the Big Ten with one loss or more, the internal calculations in the model also implied that they’d have only about a 55 percent chance of making the playoff even if they ran their record to 13-0. One can see why a computer might come to that conclusion — Iowa has played a pretty bad schedule, and its margin of victory hasn’t been impressive — but human beings are going to vote an undefeated Big Ten champion into the playoff unless almost everything else2For instance, incredibly strong contenders from the other power conferences. is working against them.Readers had some questions for us too. Why was USC, which already has three losses, given any realistic chance by the model (granted, it was just 4 percent) of making the playoff? And why was one-loss Alabama’s chance of making the playoff so much higher than its SEC championship chances? There are some good reasons for that one,3In particular, if both Alabama and Mississippi had won out, Alabama would have lost the tiebreaker in the SEC West and missed the SEC championship game. The model inferred, correctly I think, that a one-loss Alabama team probably would still have made the playoff (perhaps along with a second SEC team) under those circumstances. This became a moot point when Mississippi was spectacularly upset by Arkansas. but even accounting for those, the gap seemed to be too wide and the model seemed to be too optimistic about Alabama still making the playoff if it endured a second loss.The theme here is that human beings pay a lot of attention to wins and losses — more than our computer seemed to be doing. An undefeated power conference team is going to get in except under rare circumstances. Two-loss power conference teams have historically finished in the AP top four more often than you might think, but it’s still a hard road. And a three-loss team making the playoff? Almost impossible unless there’s total carnage everywhere else.Since the whole point of our model is to mimic human intuition, reader feedback made us think it had some blind spots. So we re-examined the historical data4Since the playoff selection committee is only one year old, this also includes the behavior of the coaches’ poll since 2002. and concluded that our model should be placing more weight on plain-vanilla wins and losses. Or at least, it should be doing so for power conference teams (and for Notre Dame); minor conference teams historically haven’t been treated that kindly by either poll voters or the committee. Even if the committee currently ranks a one-loss team ahead of an undefeated team, or a two-loss team ahead of a one-loss team, it may re-examine the case in future weeks, and the team with fewer losses will often get the benefit of the doubt. (For a more technical explanation of how this is implemented in the model, see the footnotes.5One change we introduced earlier to the model is that it reverts the projected committee standings each week toward a team’s Elo rating. Elo ratings are a fairly simple method that often correspond pretty well with human judgment in ranking sports teams. But there’s an even simpler method: a rating based solely on a team’s win-loss record and whether it plays in a power conference. The new version of the model reverts a team’s ranking based on a combination of its Elo rating and its win-loss record, instead of its Elo rating alone.)This relatively simple change has little impact for most teams, but it does affect a couple of the cases that had bothered us (and some of our loyal readers). Iowa’s chances of making the playoff are now 18 percent instead of 8 percent. Alabama’s are 42 percent instead of 54 percent. USC’s are 1 percent6USC has a decent chance of winning the Pac-12 championship, but it would take a perfect storm of circumstances to get them into the playoff even if they did. instead of 4 percent. Here’s how everyone’s odds were affected by the change: USC 6-3—19719%1%<1% UCLA 7-22321186%3%<1% RankingProbability of … Utah 8-112112122%12%2% Temple 8-122283943%<1%<1% Mississippi St. 7-22016153%3%<1% Florida State 7-21624170%<1%<1% Navy 7-1—155419%<1%<1% Stanford 8-11151152%26%5% Wisconsin 8-2—17243%<1%<1% TCU 8-1812310%11%4% Florida 8-110101438%19%3% Michigan 7-217201613%6%1% Houston 9-025223633%2%<1% Northwestern 7-2212961<1%<1%<1% Alabama 8-141435%42%12% Toledo 7-12440539%<1%<1% North Carolina 8-1—182030%5%<1% Michigan St. 8-1782212%10%1% Mississippi 7-31826109%<1%<1% So the tough part for teams like Michigan State isn’t sweating the committee’s decision if it wins the Big Ten; it’s getting to that point in the first place.

AC Milan manager Gennaro Gattuso has confirmed that he intends to retain both Andre Silva and Nikola Kalinic for next seasonSilva joined the Rossoneri last summer from FC Porto in a €38m deal, but had only found the back of the net 10 times in his 40 appearances.Prior to joining Milan, the 22-year-old had scored 21 goals in 44 matches for Porto.Meanwhile, Kalinic completed a €25m move to Milan but he has appeared to be a mere shadow of the player he was during his time at Fiorentina and the Croatia international only scored six goals all season.Serie A Betting: Match-day 3 Stuart Heath – September 14, 2019 Considering there is a number of perfect starts so early in the Serie A season, as well as a few surprisingly not-so perfect ones….But, despite a lacklustre season from both of them, Gattuso intends to keep the pair at the San Siro.“Kalinic and Andre Silva? I hope that they will improve, Andre Silva has scored. All of you keep talking about an exit for them but we will hold onto them both, tightly,” said Gattuso, via Calcio Mercato.

Comment Share your voice Facebook’s had a rough couple of years. With revelations that its platform was twisted into a tool for election interference, propaganda and harassment, as well as a breeding ground for hate speech, it’s hard to feel good about the social network these days. So Facebook has partnered with The Telegraph, a major UK newspaper, to publish more than two dozen stories as part of a promotional campaign to burnish its image. The series, called “Being human in the Information Age,” includes articles ranging from defending Facebook’s mission to “bring the world closer together” to primers on how the social network is handling cyberbullying, free expression and scammers. The partnership was first reported on by Business Insider. “There’s no doubt that the internet has changed our lives,” the introduction for the series says. “Here, we take a closer look at new challenges raised by the internet like fake news and data privacy — and how social media is tackling these challenges.” A Facebook spokeswoman said the sponsored articles were part of “larger marketing efforts in the UK with the goal of educating and driving awareness of our local investments, initiatives and partnerships here in the UK that have a positive impact on people’s lives.” The Telegraph didn’t immediately responded to a request for comment. 1 Facebook Politics Tech Industry Facebook, Instagram, Twitter: What’s your relationship… The move marks Facebook’s latest effort to respond to the deluge of criticism it’s faced in the past couple of years. Facebook CEO Mark Zuckerberg, who was once whispered about as a potential contender to run for president of the United States, spends most of his time in public defending the company’s latest snafu while extolling the virtues of what it offers to the more than 2.3 billion people who log on each month. Meanwhile, people’s trust in Silicon Valley has dropped. Roughly half of Americans told the Pew Research Center last year they don’t trust social media sites to protect their data, and 62% said in 2017 that they believe online harassment is a “major problem.” Facebook’s challenge with paying for positive articles, which are marked below the headline as “Brought to you by Facebook” to indicate they’re ads, is that they don’t always work as intended. Two days before a gunman used Facebook to livestream a massacre he committed in New Zealand, the Telegraph-Facebook partnership published an article titled “What action is Facebook taking to tackle terrorist content?” It profiled a London employee who works on Facebook’s counterterrorism team, touting how the company has removed terrorist content from its service. “Between human expertise, tooling [software development] and machine learning, we’re achieving extraordinary things, of which I’m very proud,” the Facebook employee says in the article. After the shooting, Facebook quickly found itself explaining why it had failed to identify and stop the gunman’s livestream, copies of which spread across the internet. The series also includes an article with instructions on how to protect your privacy on social media networks, particularly on Facebook. But at no point does it offer instructions on how to close and delete your account, a remedy a former Facebook executive has recommended.

Tata Steel is reportedly planning to sell its 5.5% stake in sister company Tata Motors.As per reports, the steel manufacturing arm of Tata Group is expected to execute the stake sale worth Rs 5,500 crore in “one or two tranches”.Surprisingly, the buyer is none other than its parent company Tata Group, a section of media reported quoting sources.Tata Steel also seems to be contemplating to “sell cross holding across Tata Group companies”. The company is expected to undertake debt refinancing to reduce interest charges.However, Tata Steel told CNBC-TV18 that the reports on stake sale in Tata Motors to Tata Group were “speculative”.”The company is committed to making disclosures to regulators and the investing community,” it said.Tata Motors, which will announce its earnings for June quarter on Friday, is struggling to increase its revenues due to declining volumes in China. China is the largest market for Tata Motors’ Jaguar Land Rover (JLR).Tata Motors earns more than 80% of its revenues from JLR sales. A drop in business volumes in China, which accounts for 20% of total JLR sales, weighed heavily on its profits in the March quarter last financial year (2014-15).The company profit slumped by 56.19% to Rs 1,716.50 crore in the January-March quarter compared to Rs 3,918.29 crore in the same quarter a year ago (2013-14).”Overall the environment and the numbers for Tata Motors doesn’t look good for the next couple of quarters,” said Sudip Bandopadhyay of Destimoney Securities.Owing to the weak outlook, share prices of Tata Motors have fell sharply by about 32% since the beginning of April this year.
US president Trump gives thumbs up during campaign rally in Cleveland, Ohio. Photo: reutersDonald Trump faced greater restraints on his presidency and intrusive investigations from Democrats who won control of the US House of Representatives and pledged to hold the Republican accountable after a tumultuous two years in the White House.Trump and his fellow Republicans expanded their control of the US Senate in Tuesday’s midterm elections, following a divisive campaign marked by fierce clashes over race and immigration.But they lost their majority in the House, a setback for the president after a campaign that became a referendum on his combative leadership.The split power in Congress combined with Trump’s expansive view of executive power could herald even deeper political polarization and legislative gridlock in Washington.The Democrats will now head House committees that can investigate the president’s tax returns, possible business conflicts of interest and any links between his 2016 election campaign and Russia.There may be some room, however, for Trump and Democrats to work together on issues with bipartisan support such as a package to improve infrastructure or protections against prescription drug price increases.Trump made an unlikely gesture toward Nancy Pelosi, the leader of the House Democrats who he has frequently ridiculed, saying her party should pick her to be House Speaker in the new Congress that convenes in January.”In all fairness, Nancy Pelosi deserves to be chosen Speaker of the House by the Democrats. If they give her a hard time, perhaps we will add some Republican votes. She has earned this great honor,” Trump wrote on Twitter.Earlier on Wednesday, he was less conciliatory, describing the elections results as a “very Big Win” and taking a swipe at the media. Trump was due to hold a news conference at the White House at 11:30 a.m. (1630 GMT).The Democrats fell short of a tidal wave of voter support that would have won them control of both chambers of Congress. But in the 435-member House, the party was headed for a gain of around 30 seats, beyond the 23 they needed to claim their first majority in eight years.A Senate majority would have allowed Democrats to apply even firmer brakes on Trump’s policy agenda and given them the ability to block any future Supreme Court nominees.The House Democrats could force Trump to scale back his legislative ambitions, possibly dooming his promises to fund a border wall with Mexico, pass a second major tax-cut package, or carry out his hardline policies on trade.“Today is more than about Democrats and Republicans, it’s about restoring the Constitution’s checks and balances to the Trump administration,” Pelosi told supporters at victory party.Losing the House will test Trump’s ability to compromise, something he has shown little interest in over the last two years with Republicans controlling both chambers of Congress.He hit back at the prospect of investigations by House Democrats, saying on Twitter that Republicans in Senate would counter with their own investigations of Democrats.GRIDLOCK?US stocks opened higher on Wednesday after the elections, while the dollar dropped on the reduced chances of further US fiscal stimulus.Financial markets often favor Washington gridlock because it preserves the status quo and reduces uncertainty.A Democrat-controlled House will hamper Trump’s pro-business agenda and could lead to uncertainty about his administration, but corporate tax cuts and deregulation measures that have played a large hand in the US stock market’s rally since the 2016 election are likely to remain untouched.”With the Democrats taking over the House we will now have to see what gridlock in Congress means for policy. As for the market impact, a split Congress has historically been bullish for equities and we expect to see the same pattern again,” said Torsten Slok, Chief International Economist of Deutsche Bank.Democrats will use their new majority to reverse what they see as a hands-off approach by Republicans toward Trump’s foreign policy, and push for tougher dealings with Russia, Saudi Arabia and North Korea.Foreign policy has been an area that Trump has approached in a very personal way, sometimes antagonizing allies such as Canada while making what critics see as unduly warm overtures to traditional rivals or foes.Tom Perez, chairman of the Democratic National Committee, said Democrats could work with Republicans to produce a long-awaited bill to upgrade the nation’s roads, bridges and airports.”Of course, we want to work in a bipartisan fashion. I think we can get an infrastructure bill,” he said.Trump had hardened his rhetoric in recent weeks on issues that appealed to his conservative core supporters. He threw himself into the campaign, issuing warnings about a caravan of Latin American migrants headed through Mexico to the US border and condemnations of liberal American “mobs” he says oppose him.DEMOCRATIC PROBESEvery seat in the House was up for grabs on Tuesday and opinion polls had pointed to the Democratic gains. The party with the presidency often loses House seats in midterm elections.The Republicans had an advantage in Senate races because elections were held for only 35 seats in the 100-member chamber and many of them were in states that often lean Republican.Republicans built on their slim Senate majority by several seats and ousted four incumbent Democrats: Bill Nelson in Florida, Joe Donnelly in Indiana, Heidi Heitkamp in North Dakota and Claire McCaskill in Missouri.Those gains are sure to bolster Republicans’ efforts to get conservative federal judges through confirmation proceedings. In the 36 gubernatorial contests, Democrats won in several states that supported Trump in 2016 but lost high-profile races in Florida and Ohio.Democrats could infuriate Trump by launching another congressional investigation into allegations of Russian interference on his behalf in the 2016 election. A federal probe by US Special Counsel Robert Mueller into Russia’s role in that election is ongoing.Moscow denies meddling and Trump, calling the Mueller probe a witchhunt, denies any collusion.A House majority would be enough to impeach Trump if evidence surfaced of collusion by his campaign, or of obstruction by the president of the federal investigation. But Congress could not remove him from office without a conviction by a two-thirds majority in the Republican-controlled Senate, an unlikely scenario.Most Democratic candidates in tight races stayed away from harsh criticism of Trump during the midterm campaign’s final stretch, focusing instead on bread-and-butter issues like maintaining insurance protections for people with pre-existing medical conditions, and safeguarding the Social Security retirement and Medicare healthcare programs for senior citizens.WOMEN, YOUNG, HISPANIC VOTERS FUEL GAINSThe Democratic gains were fueled by women, young and Hispanic voters, a Reuters/Ipsos Election Day poll found. Fifty-five percent of women said they backed a Democrat for the House this year, compared to 49 percent in the 2014 midterm congressional election.A record number of women ran for office this election, many of them Democrats. There were 237 women on ballots for House seats and at least 95 had won their races as of early Wednesday morning, shattering the previous record of 84 women in the House, according to the Center for American Women and Politics at Rutgers University.The party picked up seats across the map but some of the campaign’s biggest Democratic stars lost.Liberal Beto O’Rourke’s underdog Senate campaign fell short in conservative Texas against Republican Ted Cruz. Andrew Gillum lost to Republican Ron DeSantis in his quest to become Florida’s first black governor.In Georgia, Democrat Stacey Abrams was seeking to become the first black woman to be elected governor of a US state. Her opponent, Brian Kemp, was ahead in a very close race early on Wednesday and Abrams said she would not concede until all the votes were counted.
The researchers, led by Professor Joel K.W. Yang, at A*STAR (the Agency for Science, Technology and Research) in Singapore, the National University of Singapore, and the Singapore University of Technology and Design, have published a paper on the new technique for realizing 3D full-color stereoscopic prints in a recent issue of Nature Communications.”We have created possibly the smallest-ever stereoscopic images using pixels formed from plasmonic nanostructures,” Yang told Phys.org. “Such stereoscopic images do not require the viewer to don special glasses, but instead, the depth perception and 3D effect is created simply by viewing the print through an optical microscope coupled with polarizers.”The work is based on the concept of surface plasmon resonance: metal nanostructures can scatter different wavelengths (colors) of light due to the fact that the tiny nanostructures themselves resonate at different wavelengths. If a nanostructure is circular, its resonance is polarization-independent because the diameter of the circle is the same from all directions. However, if a nanostructure is biaxial (such as an ellipse or rectangle), its resonance will depend on the polarization of the incident light. By tailoring the exact dimensions of the biaxial nanopixels, researchers can generate different colors under different polarizations.Building on these ideas, the researchers in the current study have demonstrated that polarization-sensitive nanopixels that encode two sets of information can be used to produce 3D stereoscopic microprints. To do this, the researchers created nanopixels out of tiny pieces of aluminum a hundred or so nanometers across. The scientists experimented with nanopixels in two different shapes: elliptical and coupled nanosquare dimers (a pair of squares separated by a very small gap). This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. To demonstrate how these nanopixels could enable high-resolution 3D color microprints, the researchers designed a stereoscopic image containing stars on a 2D sheet by overlaying two slightly displaced views of the same image onto the same area. Then they added an x- and y-polarizer to the eyepieces of a microscope. Viewing the microprint through this stereomicroscope reveals a different image for each polarization, and the combined images appear as a 3D image.In addition to 3D prints, the polarization-sensitive nanopixels could have several other applications.”One can envision application of these prints to high-density optical information encoding or holography,” Yang said. “3D security elements that are difficult to replicate, and which offer different levels of authentication, could also be generated for anti-counterfeiting and anti-forgery technologies.”The researchers also note that it’s possible to make pixels that can encode not just two, but three or more images in a single pixel. For example, nanostructures that have circularly asymmetric shapes could have more than two polarization-dependent resonances due to the additional circularly polarized dimension. The researchers also plan to take steps toward commercialization.”Moving forward, there is much interest in developing techniques for creating such prints with significantly lower cost and higher throughput, both of which are imperative for this technology to be implementable at an industrial level,” Yang said. More information: Xiao Ming Goh, et al. “Three-dimensional plasmonic stereoscopic prints in full color.” Nature Communications. DOI: 10.1038/ncomms6361 Because these shapes are biaxial, they exhibit plasmonic resonances at different wavelengths for each axis, with the colors determined almost entirely by the dimension of the axis parallel to the polarization direction. For example, a 130-nm x 190-nm elliptical pixel appears green under y-polarized light and purple under x-polarized light. Comparing the two pixel shapes, the researchers found that the elliptical pixels have a broader range of polarization-dependent colors, while the nanosquare dimer pixels have lower levels of cross-talk, minimizing unwanted mixing of colors.

Each pixel can exhibit one of two colors depending on the polarization of the light used to illuminate it. So by viewing the pixels under light of both polarizations, two separate images can be seen. If the two images are chosen to be slightly displaced views of the same scene, viewing both simultaneously results in depth perception and the impression of a 3D stereoscopic image. © 2014 Phys.org (Left) Elliptical and coupled nanosquare pixels scatter different wavelengths of light depending on polarization.
