Leicester City’s Kasper Schmeichel is hoping club teammate Harry Maguire ends speculation surrounding his future and commit to the club.Jamie Vardy, Wilfred Ndidi and now Schmeichel have committed their futures to Leicester City, and the Denmark international hopes defender HarryMaguire will be the next to sign up for the project. The defender was a subject of summer interest from Manchester United after an impressive outing at this summer’s World Cup with England and the Foxes are keen to tie him down at the club by offering him a new contract.Schmeichel, who signed a new five-year deal on Friday, said everyone would love to see Maguire agree a new contract, but no one would put any pressure on him.Liverpool legend Nicol slams Harry Maguire’s Man United form Andrew Smyth – September 14, 2019 Steve Nicol believes Harry Maguire has made some “horrendous mistakes” recently, and has failed to find his best form since joining Manchester United.“I hope Harry signs but I don’t want to put pressure on anyone,” said Schmeichel, according to LeicesterMercury.“It is up to him, his family and his situation. I am not going to start saying anything about his situation because I don’t know enough about it.”“If he feels it is something he wants to do then we would be delighted, but it is up to him.”City certainly showed signs of their youthful promise during the 2-1 defeat to Liverpool at the King Power Stadium.
Arsenal loan star Reiss Nelson has stated that he aims to become a club legend as he dropped a hint of a possible return in JanuaryThe 18-year-old forward has already bagged six goals in seven appearances on loan at Hoffenheim this season.Following Danny Welbeck’s horrific injury last week, Nelson has been tipped to make an early return to the Emirates Stadium.Now the teenage star himself hinted that it could happen while discussing his plans to become an Arsenal legend.“Arsenal are my boyhood club,” Nelson told BBC.Merson believes Arsenal should sign Sancho Manuel R. Medina – September 14, 2019 Borussia Dortmund winger Jadon Sancho might be the perfect player to play for the Gunners, according to former England international Paul Merson.“I’ve been with them since I was eight, so that’s 10 years.“I just want to go back there stronger because at the time I was at Arsenal I was 16, 17 and I didn’t feel confident.“I didn’t think I was a man, but now I’m feeling stronger and I think a couple more months or even a year in Hoffenheim will make me strong and give me the belief and confidence to go back to Arsenal and do very good there.“I want to be an Arsenal legend. And, for England, it’s the best. You can’t beat playing for your country I don’t think.”Nelson made 15 appearances for Arsenal last season and signed a new long-term contract with the Gunners in the summer.
Share Veteran diplomats say it could take years to assess the results of this week’s nuclear summit between President Trump and North Korean leader Kim Jong Un.Trump doesn’t expect to wait that long.“I think within the first minute, I’ll know,” whether Kim is serious about giving up his nuclear weapons, the president told reporters Saturday. “Just my touch. My feel. That’s what I do.”The same impulsive confidence led Trump to accept Kim’s invitation to the summit without consulting his advisers back in March. The president abruptly called off the meeting in May, only to revive it eight days later.The two leaders are finally set to meet Tuesday morning (Monday night in the U.S.) at a luxury island resort in Singapore, the climax of a diplomatic roller-coaster rivaling any at the nearby Universal Studios theme park.“Be prepared for surprises,” said Victor Cha, a Korea expert who worked in the George W. Bush administration. “These two leaders certainly have a flair for the drama and the dramatic in these sorts of meetings.”Secretary of State Mike Pompeo, who’s met twice with Kim in preparation for the summit, said he and other advisers have been briefing Trump on a near-daily basis. But the president, who sees himself as a born deal-maker, downplayed the value of such last-minute cramming.“It’s going to be something that will always be spur of the moment,” Trump told reporters, as he left a G-7 meeting in Canada en route to Singapore. “It’s unknown territory in the truest sense. But I really feel confident. I feel that Kim Jong Un wants to do something great for his people and he has that opportunity.”Analysts say Kim will check off one of his goals simply by sharing the summit stage with Trump. The first such meeting with a sitting U.S. president will help rebrand the North Korean leader from pariah to peacemaker.“Just the fact of a superficially successful summit is a big gain for him,” said Richard Bush, a senior fellow at the Brookings Institution. “He has sat across the table from the president of the United States, the superpower. That elevates his position, prestige, and power tremendously.”Cracks in the sanctions campaignCracks have also begun to appear in the “maximum pressure” campaign of economic sanctions against North Korea, even though Trump insists the U.S. won’t loosen the screws until Pyongyang’s nuclear program is dismantled.“As long as the summitry is going on, and Kim Jong Un is going to be invited to the United Nations and so forth, it will be very hard to get China, Russia, even South Korea back on board,” said Michael Green, who oversaw Asia policy on the National Security Council in the George W. Bush administration. “The leverage will be dissipated.”Brookings scholar Jung Pak agrees.“Whether we like it or not, the other countries see this as the U.S. turning the spigot back on,” Pak said.The U.S. goal for the summit is straightforward: the complete, verifiable, irreversible end of North Korea’s outlawed nuclear weapons program.“A perfect track record of cheating”But while Kim has made some gestures in that direction — suspending nuclear and missile tests and making a show of disabling a nuclear test facility — veteran diplomats are skeptical that North Korea will surrender its nuclear weapons altogether.“I do not know of a single U.S. official — and we talked to a lot of them — or Japanese official below the level of the president who thinks North Korea is going to denuclearize,” Green said.In the 1990s and again the early 2000s, North Korea agreed to halt its nuclear program only to continue with clandestine research. With each round of diplomacy, Pyongyang’s weapons grew more advanced and more dangerous.“We’ve had multiple deals with North Korea,” Green said. “We now know they have a pretty good track record in these negotiations: a perfect track record of cheating every time.”Pompeo said he’s received personal assurances from Kim that North Korea is ready to denuclearize.“President Trump is hopeful, but he’s also going into the summit with his eyes wide open,” Pompeo told reporters. “We’ve seen how many inadequate agreements have been struck in the past. And you can be sure that President Trump will not stand for a bad deal.”Timing and verificationTiming and verification will be crucial to the success of any nuclear deal. But those details aren’t likely to be worked out during this week’s summit and will instead have to wait for follow-up conversations.The administration has backed away from its demand for immediate disarmament, acknowledging that a weapons program a large as North Korea’s would take time to wind down.But officials still wants to see rapid movement.“This has to be big and bold,” Pompeo said. “We can’t step through this over years.”In exchange for North Korea’s cooperation, the administration is offering Kim both security guarantees and economic aid.“He’ll be safe. He’ll be happy. His country will be rich,” Trump said last month.Analysts suggest the president may be underestimating the value that Kim’s family has placed on nuclear weapons for three generations, substituting his own businessman’s priorities for the North Korean leader’s.“If the North Koreans wanted to be rich, they could have been rich a long time ago,” Cha said.“For Kim, the nuclear weapons are part of his national identity,” Pak added. “To assume that one can go in and talk about making him rich is almost antithetical, almost offensive in a way, for somebody who has achieved and completed his grandfather’s goal.”An end to the Korean War?The summit could also produce some sort of declaration — short of a formal treaty — about ending the Korean War, 65 years after the armistice. Eventually, that could lead to pressure from North Korea and China to withdraw many of the 28,000 American troops in South Korea.Trump, who has complained about the cost of those troops, might welcome the opportunity, though a troop withdrawal would also reinforce doubts about America’s commitment to the Asia-Pacific region.The president has also promised Japan’s prime minister, Shinzo Abe, that he will press Kim for the return of Japanese citizens who have been kidnapped and held captive in North Korea. And Trump has said he may raise the issue of North Korea’s dismal human rights record with Kim, although he didn’t do so during a White House meeting with one of Kim’s top deputies.Whatever complications may arise after the summit, both sides seem eager to stage a smiling photo of the historic handshake.“No matter what happens, President Trump and Kim Jong Un are going to call it a success,” said former CIA analyst Sue Mi Terry, who’s now a senior fellow at the Center for Strategic and International Studies. “Both leaders are invested in this and they want to. So the optics are going to look good.”Even those who are skeptical of North Korea’s intentions don’t want a return to last year’s open hostility, when Trump and Kim were calling each other names and boasting about their nuclear buttons.Despite Trump’s confidence in his deal-making instincts, though, the ultimate outcome of the summit probably won’t be known quickly.“President Trump would like to see this as a very different, bigger deal,” Cha said. “Everybody else screwed it up. Now he’s going to fix it.”But the veteran diplomat, who was briefly considered for a post as Trump’s ambassador to South Korea, warns the administration will face the same challenges and trade-offs in North Korea that its predecessors did.“We want to solve this problem. But we may be stuck managing it.” Copyright 2018 NPR. To see more, visit http://www.npr.org/.
Bending the norm on nanowires Scientists have discovered how to align silver nanowires in a controlled manner with an electric field. Their technique offers a possible route to sculpting and writing on nanowires, an ability that will likely have applications in industrial manufacturing. This series of scanning electron microscope images shows how increasing an electric field can align a bundle of silver nanowires, from disordered (a) to highly aligned (d). The white arrow indicates the direction of the electric current, which caused silver ions to migrate in the opposite direction.

Explore further Silver, one of the most precious metals for its shimmering beauty, also has the highest electrical conductivity of all metals. This property enabled a team of scientists from the Tsinghua University P.R. China to observe that a direct current electric field can align one-dimensional, 60 nm-diameter silver nanowires. The ability to control silver nanowire alignment will likely lead to the development of nanoelectronics as well as nanoscale photonic structures.“This is the first time an electric field has been used to align silver nanowires,” Jialin Sun, coauthor of the paper recently published in Nanotechnology, told PhysOrg.com. “The high quality alignment of nanowires can help form optimal nanoscale optoelectronic devices with periodic structure.”The electric field-alignment technique works because of the fact that the silver compound used by the scientists is a solid electrolyte at room temperature. As an electrolyte, silver ions can roam freely, and diverge from their crystalline lattices. So when the scientists applied an electric field, the disordered silver ions were free to align themselves under the field.The study also found that the degree of alignment increased with an increase of the electric field strength. The series of images above, taken by a scanning electron microscope, shows the effect of progressive electric field strengths on a bundle of silver nanowires. In the experiment, the silver ions tended to migrate along the direction of the current, causing the nanowires to “grow” parallel to the direction opposite the current. In the case of the strongest (400 V m-1) electric field, the nanowire bundle clustered into a dense, sheet-like structure. In fact, the nanowires actually became denser after the applied electric field, further enhancing their usability for nanoelectronics applications.“The alignment of nanowires can be effectively controlled by adjusting the applied DCEF [direct current electric field] strength between the two electrodes, and improved by increasing the DCEF strength,” the scientists wrote.In addition to the novelty, this method’s ease of preparation has smoothed the road toward prospective applications. Because the electric field-alignment technique can occur at room temperature, at normal atmospheric pressure and without any complicated and collapsible templates, the method has overcome many of the challenges of current approaches to nanowire alignment.“It is believed that the synthesized alignment of metallic nanowires can be easily realized under normal conditions,” said Sun. “This technique will be very important for the process of industrial manufacturing. For example, this method can be used for the preparation of metallic nano-circuits, nanowire-grid polarizers, nanoscale photon crystals, nanoscale optical wave guides, and so on.”The scientists also project that an electric field could “sculpt” nanowire structures, drawing lines and shapes with a scanning tunneling microscope.

Facebook is serious about its user community following rules about what is posted on user and group pages. For that reason, they have added a section to the Support Dashboard for users that come across postings or pictures that break the rules so that they can be reported and removed. In looking at how Facebook handled such reports for objectionable photos, Kumar noticed that the code for sending the request could be viewed by the user making the request. He then discovered that the code could be modified as well. Normally, when a report is created it is sent to Facebook, where someone on staff looks at the picture in question and makes a judgment about whether to let it remain or to delete it. If they choose to let it remain, a message is created with a link in it and sent to the owner of the account that holds the photo. That person can then either choose to let the photo remain on their page, or can click the link to have it instantly removed. Kumar found that he could alter the address to which the message would be sent, which meant he could have it sent to himself, rather than the account holder. Once the message was received, he was then free to click the link to delete the photo. That meant he could delete photos from any account, personal or group—even those posted by others on someone’s page, without permission from them or Facebook, and without the knowledge of either. The owner of the page wouldn’t know anything had occurred unless they happened to notice a photo missing on their page.Kumar very carefully followed the rules Facebook has outlined for reporting vulnerabilities (he didn’t remove pictures from real user accounts, for example) and was handsomely rewarded for his efforts. He reports that Facebook has subsequently fixed the vulnerability. © 2013 Phys.org (Phys.org) —An electronics and communications engineer in India has been awarded a $12,500 bounty by Facebook for the discovery of a picture deleting vulnerability in the social network’s Support Dashboard. Arul Kumar details on his blog how he found the vulnerability, how it works and his communications with Facebook regarding the find. This document is subject to copyright.
