Toure Yaya thinks Paul Pogba is very similar to him

first_imgDuring an interview with Sky Sports, Toure Yaya praised Paul Pogba and explained why Jose Mourinho misused him at Manchester United.The Ole Gunnar Solskjaer effect on Paul Pogba was explained earlier on Monday by Toure Yaya, there is an undeniable improvement that the French midfielder had since Jose Mourinho left the club and it’s mostly related to the urge that Paul has to impress his manager.Some people may think that the French player didn’t deliver the results expected from him because he had a grudge against the Portuguese manager, but Toure doesn’t think that’s the case.In fact, Yaya is convinced that Pogba tried to play his best football but the problems lied in Jose Mourinho’s lack of understanding he had of the player. In a way, the Frenchman was going through a very similar problem that Toure Yaya went through with Pep Guardiola and he feels very identified with the way things developed in the last few months.It wasn’t until the Ivorian player moved from Barcelona to Manchester City when he started showing his true self as a versatile midfielder who couldn’t only defend, but also had some very impressive stats as an attacking midfielder.Paul Pogba suffered that same problem, as Jose Mourinho always regarded him as a player who was very similar to the likes of N’Golo Kante, Blaise Matuidi or Fernandinho.Paul Pogba has more belief in Ole Gunnar Solskjaer now and wants to “feel the love” from his manager, Yaya Toure has said.https://t.co/NoVYzw8XP6— Sky Sports Premier League (@SkySportsPL) January 14, 2019It’s almost as if Jose Mourinho completely forgot to watch Pogba during his time at Juventus, which was the place where he proved the world what he was capable of.With the Italian giants, Paul delivered outstanding performances every single week as an all-terrain midfielder who had the ability to be omnipresent all over the pitch and never gave up his attacking nature.During the match against Tottenham, there was actually a moment in the second half when Pogba didn’t like that the Manchester United left-back failed to go back to his position when the Red Devils lost a ball and he made an impressive 50-yard run just to cover the whole that his teammate left open.Right after that play, we could see Pogba arguing with a player who was out of frame but he never gave up on his intention to help out the squad on defense.Harry Maguire, Manchester UnitedSolskjaer praises Harry Maguire after Man United’s 1-0 win Andrew Smyth – September 14, 2019 Ole Gunnar Solskjaer singled out Harry Maguire for praise after helping Manchester United keep a clean sheet in their 1-0 win over Leicester City.During his time with Jose Mourinho, Paul Pogba never gave up that defensive nature but the manager did limit him to a certain place on the pitch in the most important matches.For Toure Yaya, Pogba’s awakening has a lot more to do with that newly acquired freedom than proving a point to the Portuguese manager.Yaya Toure: “He (Pogba)can deliver like he has done in the past at Juventus. He can shoot from far, he can pass – it’s what the fans want and it’s what the club has paid for this kind of player. What he has to do now is to continue to believe in himself.” #mufc [Sky]— United Xtra (@utdxtra) January 14, 2019Perhaps Yaya Toure is one of the very few players who completely understand what Paul Pogba was going through, as he was one of the most affected professionals who needed to prove themselves repeatedly in order to be fully understood by their manager.Now that life seems to be smiling back at him, Pogba is getting a new chance to give the fans what they have been demanding from him all this time.“A player like me, I just want to give more, produce more, and I like the challenge,” said Toure on Sky Sports.“Sometimes it has been very difficult because to be able to deliver your best qualities, you can’t say to Pogba to be like N’Golo Kante or Blaise Matuidi, it is impossible.”“But what he has delivered in the past at Juventus… he can shoot from far, dribble, give passes like he did this weekend against Tottenham. It’s what the fans want and what the club has paid for in this type of player.”Just make sure it continues. He has to now continue to believe in himself. Criticism is going to come in all day long, but he’s a professional man, and you have to accept it and continue to work hard,” he added.What do you think is the most striking similarity between Paul Pogba and Yaya Toure’s style of play?

Razer Respawn mental performance drink mix wants to up your game

first_img Post a comment Gaming Culture Wellness See All More from E3 • Most of the ingredients are the various B vitamins found in energy drinks and antioxidants.  But while Respawn is sugar free — it uses the artificial sweetener Sucralose — it has maltodextrin, a complex carbohydrate that allows the powder to stay all powdery. That’s why it has 20 calories. But maltodextrin breaks down into… sugar. And it has a higher glycemic index than… sugar. So you may still get the spike and crash, and you definitely need to factor it in if you’re diabetic or on a keto diet. It really depends upon how much maltodextrin is in it.

Razer Razer launched an April Fool’s campaign in 2010 for a gamer-focused drink, Project Venom V2. It turns out that seemed like such a good idea to some people that the company turned it into a real product in time for t his year”s E3, Razer Respawn (not to be confused with Jedi: Fallen Order developer Respawn Entertainment). But don’t call it an “energy drink” — it’s a “mental performance drink mix” that “contains premium ingredients that help support increased focus, reaction time, and mental stamina.”Respawn comes in single-serving powder packets that you mix with 16-20 ounces of water. A box with 20 packets of an individual flavor runs $25 (at Razer and Amazon); flavors are green apple, tropical pineapple, pomegranate watermelon and blue raspberry. You can also spring for the $30 custom shaker, which does not support Chroma, but that would be awesome. According to Razer, a serving has 20 calories and 95mg of caffeine. The full ingredient list is:Maltodextrin, Citric Acid, Green Tea Extract, Sucralose, L-theanin, Choline Bitartrate, Caffeine, Natural and Artificial Flavor, Ground Ginger, Modified Corn Starch, Corn Syrup solids, Niacinamide, D-calcium Pantothenate, Silicon Dioxide, Blue No. 1, Pyridoxine Hydrochloride, Cyanocobalamin.Razer distinguishes Respawn from energy drinks, saying “they tend to have excessive caffeine and sugar, giving you an initial burst but eventually leading to jitters or a physical crash.”   0 As for caffeine, one serving of sugar-free Red Bull has 80mg; Respawn’s 95mg of caffeine for a single serving is higher, but because the serving size is bigger (16-20 oz vs. 8.5 oz for Red Bull), math makes the amount smaller if you look at it by volume instead of serving size. The equivalent amount of Red Bull has 150mg or so. (In either case, they’re both less than the approximately 330mg in my morning coffee.)Razer does caution not to drink more than three servings per day.

Leave or we will kill you all

first_imgSmoke is seen on Myanmar’s side of border as Rohingya refugees collect their belongings on a shore after crossing the Bangladesh-Myanmar border by boat through the Bay of Bengal in Shah Porir Dwip. Photo: ReutersThousands of Rohingya Muslims in violence-racked northwest Myanmar are pleading with authorities for safe passage from two remote villages that are cut off by hostile Buddhists and running short of food.“We’re terrified,” Maung Maung, a Rohingya official at Ah Nauk Pyin village, told Reuters by telephone. “We’ll starve soon and they’re threatening to burn down our houses.”Another Rohingya contacted by Reuters, who asked not to be named, said ethnic Rakhine Buddhists came to the same village and shouted, “Leave, or we will kill you all.”Fragile relations between Ah Nauk Pyin and its Rakhine neighbours were shattered on 25 Aug, when deadly attacks by Rohingya militants in Rakhine State prompted a ferocious response from Myanmar’s security forces.At least 430,000 Rohingya have since fled into neighbouring Bangladesh to evade what the United Nations has called a “textbook example of ethnic cleansing”.About a million Rohingya lived in Rakhine state until the recent violence. Most face draconian travel restrictions and are denied citizenship in a country where many Buddhists regard them as illegal immigrants from Bangladesh.Tin Maung Swe, secretary of the Rakhine state government, told Reuters he was working closely with the Rathedaung authorities, and had received no information about the Rohingya villagers’ plea for safe passage.“There is nothing to be concerned about,” he said when asked about local tensions. “Southern Rathedaung is completely safe.”National police spokesman Myo Thu Soe said he also had no information about the Rohingya villages but that he would look into the matter.Asked to comment, a spokeswoman for the US State Department’s East Asia Bureau made no reference to the situation in the villages, but said the United States was calling “urgently” for Myanmar’s security forces “to act in accordance with the rule of law and to stop the violence and displacement suffered by individuals from all communities.”“Tens of thousands of people reportedly lack adequate food, water, and shelter in northern Rakhine state,” spokeswoman Katina Adams said. “The government should act immediately to assist them.”Adams said Patrick Murphy, the US deputy assistant secretary of state for East Asia, would reiterate grave US concern about the situation in Rakhine when he meets senior officials in Myanmar this week.Britain is to host a ministerial meeting on Monday on the sidelines of the annual UN General Assembly in New York to discuss the situation in Rakhine.NO BOATSAh Nauk Pyin sits on a mangrove-fringed peninsula in Rathedaung, one of three townships in northern Rakhine state. The villagers say they have no boats.Until three weeks ago, there were 21 Muslim villages in Rathedaung, along with three camps for Muslims displaced by previous bouts of religious violence. Sixteen of those villages and all three camps have since been emptied and in many cases burnt, forcing an estimated 28,000 Rohingya to flee.Rathedaung’s five surviving Rohingya villages and their 8,000 or so inhabitants are encircled by Rakhine Buddhists and acutely vulnerable, say human rights monitors.The situation is particularly dire in Ah Nauk Pyin and nearby Naung Pin Gyi, where any escape route to Bangladesh is long, arduous, and sometimes blocked by hostile Rakhine neighbours.Maung Maung, the Rohingya official, said the villagers were resigned to leaving but the authorities had not responded to their requests for security. At night, he said, villagers had heard distant gunfire.“It’s better they go somewhere else,” said Thein Aung, a Rathedaung official, who dismissed Rohingya allegations that Rakhines were threatening them.Only two of the 25 Aug attacks by the Arakan Rohingya Salvation Army (ARSA) took place in Rathedaung. But the township was already a tinderbox of religious tension, with ARSA citing the mistreatment of Rohingya there as one justification for its offensive.In late July, Rakhine residents of a large, mixed village in northern Rathedaung corralled hundreds of Rohingya inside their neighbourhood, blocking access to food and water.A similar pattern is repeating itself in southern Rathedaung, with local Rakhine citing possible ARSA infiltration as a reason for ejecting the last remaining Rohingya.‘ANOTHER PLACE’Maung Maung said he had called the police at least 30 times to report threats against his village.On 13 Sept, he said, he got a call from a Rakhine villager he knew. “Leave tomorrow or we’ll come and burn down all your houses,” said the man, according to a recording Maung Maung gave to Reuters.When Maung Maung protested that they had no means to escape, the man replied: “That’s not our problem.”On 31 Aug, the police convened a roadside meeting between two villages, attended by seven Rohingya from Ah Nauk Pyin and 14 Rakhine officials from the surrounding villages.Instead of addressing the Rohingya complaints, said Maung Maung and two other Rohingya who attended the meeting, the Rakhine officials delivered an ultimatum.“They said they didn’t want any Muslims in the region and we should leave immediately,” said the Rohingya resident of Ah Nauk Pyin who requested anonymity.The Rohingya agreed, said Maung Maung, but only if the authorities provided security.He showed Reuters a letter that the village elders had sent to the Rathedaung authorities on 7 Sept, asking to be moved to “another place”. They had yet to receive a response, he said.VIOLENT HISTORYRelations between the two communities deteriorated in 2012, when religious unrest in Rakhine state killed nearly 200 people and made 140,000 homeless, most of them Rohingya. Scores of houses in Ah Nauk Pyin were torched.Since then, said villagers, Rohingya have been too scared to leave the village or till their land, surviving mainly on monthly deliveries from the World Food Programme (WFP). The recent violence halted those deliveries.The WFP pulled out most staff and suspended operations in the region after 25 Aug.Residents in the area’s two Rohingya villages said they could no longer venture out to fish or buy food from Rakhine traders, and were running low on food and medicines.Maung Maung said the local police told the Rohingya to stay in their villages and not to worry because “nothing would happen,” he said.But the nearest police station had only half a dozen or so officers, he said, and could not do much if Ah Nauk Pyin was attacked.A few minutes’ walk away, at the Rakhine village of Shwe Long Tin, residents were also on edge, said its leader, Khin Tun Aye.They had also heard gunfire at night, he said, and were guarding the village around the clock with machetes and slingshots in case the Rohingya attacked with ARSA’s help.“We’re also terrified,” he said.He said he told his fellow Rakhine to stay calm, but the situation remained so tense that he feared for the safety of his Rohingya neighbours.“If there is violence, all of them will be killed,” he said.last_img read more

New study of crows and parrots highlights different types of intelligence

first_imgThe Multi-Access-Box (MAB). (PhysOrg.com) — In an experiment designed to illustrate the different ways that animals use their own unique type of intelligence to accomplish certain goals, a team of zoologists and biologists from the University of Vienna and Oxford University, led by biologist Dr. Alice Auersperg have shown that New Caledonian crows and a type of green parrot called the kea, are both able to accomplish similar difficult tasks, but go about doing so in very different ways. In a paper published in PLoS ONE, the team describe how when confronted with a box with food inside, both species of birds showed high levels of intelligence in getting at that food, but went about doing so in ways uniquely suited to their physical and behavioral attributes. More information: Auersperg AMI, von Bayern AMP, Gajdon GK, Huber L, Kacelnik A (2011) Flexibility in Problem Solving and Tool Use of Kea and New Caledonian Crows in a Multi Access Box Paradigm. PLoS ONE 6(6): e20231. doi:10.1371/journal.pone.0020231AbstractParrots and corvids show outstanding innovative and flexible behaviour. In particular, kea and New Caledonian crows are often singled out as being exceptionally sophisticated in physical cognition, so that comparing them in this respect is particularly interesting. However, comparing cognitive mechanisms among species requires consideration of non-cognitive behavioural propensities and morphological characteristics evolved from different ancestry and adapted to fit different ecological niches. We used a novel experimental approach based on a Multi-Access-Box (MAB). Food could be extracted by four different techniques, two of them involving tools. Initially all four options were available to the subjects. Once they reached criterion for mastering one option, this task was blocked, until the subjects became proficient in another solution. The exploratory behaviour differed considerably. Only one (of six) kea and one (of five) NCC mastered all four options, including a first report of innovative stick tool use in kea. The crows were more efficient in using the stick tool, the kea the ball tool. The kea were haptically more explorative than the NCC, discovered two or three solutions within the first ten trials (against a mean of 0.75 discoveries by the crows) and switched more quickly to new solutions when the previous one was blocked. Differences in exploration technique, neophobia and object manipulation are likely to explain differential performance across the set of tasks. Our study further underlines the need to use a diversity of tasks when comparing cognitive traits between members of different species. Extension of a similar method to other taxa could help developing a comparative cognition research program.

Video: PLOS ONE, doi:10.1371/journal.pone.0020231 In the video that accompanies the paper, it’s easy to see the differences in the bird’s makeup; the crows are careful and appear worried about being seen while working to get at the food, while the keas throw caution to the wind and attack the box with abandon, resorting to using the tools and such only when they find they can’t simply knock the box apart or turn it over. In some respects, it’s sort of like watching the difference between cats and dogs. Cats slowly stalk their prey, sneaking up on it and catching it by surprise, whereas dogs bound in, all engines firing, hoping to outrun or outlast whatever it’s trying to catch. © 2010 PhysOrg.com Explore furthercenter_img This document is subject to copyright.

It’s beak was never meant for such a task, so, he resorts to using both beak and claws to work the rod until finally figuring out a way to push it through the hole and then to shove it at the food. You can’t help but wonder how some of us human beings would have done under similar circumstances. The box was constructed of clear see-through plastic and had four walls, each of which had a means of allowing access to a bit of food mounted on a pedestal in the center of the box. The first method, and the one that all the birds tested found the easiest, was a string protruding from a wall that was tied to the food; pulling on it resulted in the food being yanked off its platform and rolling downhill and out of the box. The next wall consisted of a hole with a tube leading downhill to the food; pushing a marble through the hole caused it to roll downhill knocking off the food. The next wall consisted of nothing but a hole in the wall, which meant to get the food treat, the birds had to shove a wooden rod through the hole to knock it off its pedestal. And lastly, the fourth wall had a window that could be opened outward by use of a hook, thus allowing access to the inside of the box and the treat.

The origins of handedness in life

first_img © 2014 Phys.org Finding supports model on cause of DNA’s right-handed double helix Handedness is a complicated business. To simply say life is left-handed doesn’t even begin to capture the blooming hierarchy of binary refinements it continues to evolve. Over the years there have been numerous imaginative theories for how life’s amino acids, nucleic acids, and sugars came to favor one orientation over another. Everything from circularly polarized UV light, magnetism of the Earth, oriented clays or quartzes, to the weak nuclear force itself has been considered, but none has yet to securely emerge into realm of plausibility. A recent paper by Dreiling and Gay in Physical Review Letters has now thrown a life jacket to the weak force making it a theoretically viable possibility. To fully vet the author’s conception a little work needs to be done. Effort well spent we might say, because to understand where and when the handedness of life’s molecules originated is to know the origin of life. Citation: The origins of handedness in life (2014, October 1) retrieved 18 August 2019 from https://phys.org/news/2014-10-handedness-life.html Journal information: Physical Review Letters Explore further The capital “L” forms of aminos acids are the chiral orientations mostly preferred in our proteins. They are said to be left-handed when referenced to the optical activity of an L-glyceraldehyde molecule from which they could in theory be derived. However nine of our nineteen L-amino acids are actually dextrorotatory with a lowercase d (rotate polarized light to the right), when measured at the standard optical wavelength of 589 nm. Similarly the D orientation of glucose, the dextrose of life, rotates light to the right, while D-fructose actually rotates it to the left. The handedness of the DNA helix is more straightforward to assign than values for optical rotation of constituent molecules with multiple chiral centers. The A-DNA helix which life mostly employs, threads to the right when viewed from either direction as sure as a nut threads in either direction on the machinist’s screw. While the debate continues on the exact order in which the many key molecules of life first appeared, amino acids have been the center of attention. One possible explanation for their chirality is that circularly polarized (CP) light preferentially destroyed one amino acid enantiomer over the other, potentially giving it a head start. This idea gained some support when CP radiation in the infrared band was discovered in the Orion Nebula. The main problem with this idea is that CP also destroys much of the “correct” amino acid form as well. Moreover, the magnitude and orientation preference for the effect depends on the frequency of the light. The desireable bias—L selection for the narrow UV light band—would be swamped by competing broadband effects with the result that any long term amplification would grow asymptotically small.Experimentatlly, the CP theory of handedness is not completely dead, only weak. The best result to date has been the creation of 20% optically pure camphor in the lab. Unfortunately this was only obtained after 99% of the original stock was destroyed. If the D form amino acids are life’s cancer, than CP light hardly seems to be the most effective chemotherapy. The weak nuclear force, one the other hand, may be a bit more interesting for the origins of chirality. It is one of the four fundamental forces of nature and governs a particular kind of radioactive decay known as β-decay. The weak force has a peculiar handedness, called parity violation, which preferentially produces left-handed electrons during β-decay. For electrons with a left-handed “helicity”, the directions its of spin and motion are opposite to each other.center_img More information: Chirally Sensitive Electron-Induced Molecular Breakup and the Vester-Ulbricht Hypothesis J. M. Dreiling and T. J. Gay, Phys. Rev. Lett. 113, 118103 – Published 12 September 2014. journals.aps.org/prl/abstract/ … ysRevLett.113.118103 Chirality of life. Credit: wikipedia Richard Feynman Beta decay, and the events occuring around it, are perhaps much better described with Feyman diagrams than with words. For many of us, simply explaining why a mirror “appears” to flip left and right but not top and bottom requires more than just imagining circling around it to appear inside it. Determining the far more complex mechanisms that underlie life’s handedness will likely remain a significant challenge for some time. In 1967 Vester and Ulbricht suggested that spin-polarized electrons could have directly generated the kind of CP light described above (as so-called bremsstrahlung radiation) to directly enrich the enantiomeric precursors of life. While notable, that mechanism leaves us right back where we were with the CP light shortcomings mentioned above. In this void, other researchers have suggested the polarized electrons themselves, either from radioactive decay or as cosmic rays hailing at the appropriate energy, might be the emissaries of chirality. Against this tableau of uncertaintly there is an interesting theoretical implication of parity violation. That is that both L-amino acids and D-sugars are slightly more stable then their opposites. Unfortunately, the energy differences we are talking about here are only about 10–17 kT. In a racemic mixture of L and D form amino acids, that energy corresponds to an L excess of only one per every 6×10^17 molecules.Finding evidence that direct beta interactions can transmit chirality to organic molecules has been difficult. What distinguishes the results just reported by Dreiling and Gay is that the uncertainty regarding a photonic or electronic mechanism can be reduced by mimicking beta radiation with longitudinally polarized electrons produced in the laboratory at a precisely controllable energy. The researchers used a brominated form of camphor in which an electron could cause release of the bromine in a process known as dissociative electron attachment (DEA). The key to their success was to use incident electrons with low velocity and energy to maximize the “chirality sampling” interactions.In a nutshell, they found that left-handed bromocamphor reacted better with right-handed electrons at modest energies, and better with left-handed electrons at the lowest energies. The effect was small, but enough to take the Vester-Ulbricht Hypothesis to the next level. This document is subject to copyright.

US now requires registration of all drones sets January deadline

first_imgUS authorities concerned about safety implications of drones announced plans earlier this year to require registration. Image Credit: techpp Advertisement That drone under the Christmas tree? If you are a US resident, you will need to register it by February 19 or face a possible fine.Rules released Monday by the US Federal Aviation Administration require registration of small unmanned aircraft weighing more than 250 grams (0.55 pounds) and less than 25 kilograms (55 pounds) including payloads such as on-board cameras.The registration fee is $5, but in an effort to encourage people to register quickly, the FAA will waive the fee through January 20.“Make no mistake: unmanned aircraft enthusiast are aviators, and with that title comes a great deal of responsibility,” said US Transportation Secretary Anthony Foxx in a statement. – Advertisement – “Registration gives us an opportunity to work with these users to operate their unmanned aircraft safely. I’m excited to welcome these new aviators into the culture of safety and responsibility that defines American innovation.”US authorities concerned about safety implications of drones announced plans earlier this year to require registration.For recreational drone pilots in the United States, the flight rules are clear: no higher than 400 feet (120 meters), always within sight and nowhere near an airport without prior permission.Owners will be able to use a streamlined online registration system, using a unique identification number for each drone. The registration is valid for three years.Civil penalties for failing to register can go up to $27,500.The Consumer Technology Association, which represents electronics startups and manufacturers, welcomed the streamlined registration process but objected to the new fee.“We disagree with the decision to impose a five-dollar registration fee a ‘drone tax,’ which will hamper registration and discourage compliance,” said Douglas Johnson, a vice president of CTA, formerly known as the Consumer Electronics Association.“With the federal rule’s arrival, the administration must now focus on two critical tasks: informing consumers about the registration program and avoiding unnecessary and duplicative registration proposals at the state and local levels.”[related-posts]The association said it expects the US market will approach $105 million in revenue, up 52 percent from a year ago, with unit sales growing 63 percent to 700,000.[Gadget 360]last_img read more
