The Egyptian midfielder has signed an extension of his contract, which is yet to be disclosed, with the Gunners. Since he joined Wenger, he has made 65 appearances for the team.Elneny joined Arsenal back in 2016 and since then, Wenger has been always proud of his skills, which is exhibited by the extension of his contract.“He is a fantastic boy, we love him here. His best years are in front of him,” Wenger shared regarding the Egyptian at the beginning of the season.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.“Officially we will be together for a longer time, in order to reach what we started, and to put Arsenal in it’s deserved spot in Europe and the whole world,” was the official statement of the player, shared in his official twitter profile, according to the Daily Mail.“We’re pleased to announce that Mo Elneny has signed a new long-term contract with the club,” was Arsenal’s official statement on the matter.
(PhysOrg.com) — Researchers at HP Labs, the central research arm of HP, have discovered that a resistor with memory, a “memristor” can also perform logic operations. This means chips storing data may also be able to carry out computations without the need for a central processing unit (CPU). The discovery could mean computers will be able to become more compact and efficient than imagined previously. HP Labs first demonstrated the memristor in 2008 (see the PhysOrg article), but its theoretical existence was postulated in 1971 by Professor Leon Chua of the University of California at Berkeley. He named them memristors since they combine the electrical properties of a memory element and a resistor. They are able to retain a memory of the amount of charge that flowed through them after the power is turned off, and the resistance depends on the voltage history. According to HP Labs these tiny devices are the fourth basic building blocks of electronics, the others being resistors, capacitors and inductors.

Each memristor is composed of two layers of titanium dioxide connected by wire. As electrical current is applied to one layer, the small signal resistance of the other layer is changed, which may in turn be used as a method to register data. © 2010 PhysOrg.com Self-Programming Hybrid Memristor/Transistor Circuit Could Continue Moore’s Law Now a team of researchers from the HP Information and Quantum Systems Laboratory at Palo Alto, California, have created architectures for memory chips using memristors, including one in which a stack of memristors are layered in a single chip. The team, led by the director of the laboratory, R. Stanley Williams, believe devices using the element could be developed for commercial use within a few years. These could allow supercomputers to work dramatically faster than today, and because memristors retain their memory, computers based on them could be turned off and on like a light switch. In a news release HP Labs said memristors are faster than current storage devices such as flash memory, and they use less energy and can store more than double the data. They could also be used in handheld devices with ten times more embedded memory than today’s devices. HP Lab predicts memristor-based processors could eventually replace silicon in uses such as e-reader display screens.Memristors are also unaffected by radiation, which can affect transistor-based technologies, and this means they could enable the development of smaller and more powerful devices, since the use of transistors is limited by Moore’s Law, which says the number of transistors that can be packed into a chip for a fixed cost has doubled every two years. Transistors on the most advanced chips have feature sizes as low as 22 nanometers, but there is a limit to how small they can become.Williams said that as “our brains are made of memristors,” the discovery could lead to computers that work more like human brains.The paper was published in Nature last week.

They also were able to predict the secondary assembled structure of PRE-1 RNA using RNAstructure Webservers ( rna.urmc.rochester.edu/RNAstru … edict1/Predict1.html ). The upshot of all this work, in the author’s own words, is that the ‘genomic performance of PRE-1 in terms of 7SL RNA-derived SINEs seemed convincing enough to classify the suidae into a family mainly inhabited by primates’.It has not escaped our attention that many readers of physorg who may have availed themselves of our previous coverage of the human hybrid origins theory, and a later follow up report, might come to premature conclusions here. With that in mind, I talked the creator of the hybrid origins theory, Eugene McCarthy, to get his take on this new research. He had this to say:”People have been congratulating me on this SINE study as if it somehow proved the hybrid theory of human origins. That’s nice of them, but it’s just one run in a nine-inning game. True, it does show that pigs are more closely related to primates than has generally been thought, which in turn suggests that a hybrid cross between pig and chimpanzee is more feasible than many have supposed. But to establish whether we’re actually descendants of an ancient cross between pig and chimpanzee, will require a detailed search of the human genome, not just a study of SINEs. I’ve explained the relevant issues in a recent rebuttal of some of the most common criticisms of the hybrid theory. It’s not as simple as some people like to think.” © 2015 Phys.org This document is subject to copyright.

The Laurasiatheria are the placental mammals believed to have hailed from the northern supercontinent of Laurasia after it split from Gondwana when Pangaea broke up. Their sister group, the Euarchontoglires, are the Supraprimates. These consensus classifications were made using the larger family of retrotransposons of which SINEs, and longer related LINEs, are themselves members of.In the pig genetics business, the preferred classification term for the family is ‘suidae’. Suidae PRE elements have been known since their original discovery back in 1987. The researchers identified the PRE1 element as a polymorphic insertion in the 5′-flanking region (about 686~985 bp upstream from the transcription initiator ATG codon) of the insulin growth factor binding protein (IGFBP7). Postulating that this 300 base pair insert sequence might be related to Alu inserts, they compared it with representative primate Alu sequences selected from the AF-1 database (software.iiar.res.in/af1/index.html). Incidentally, we should note that pig geneticists don’t have a monopoly on the term PRF-1. In related areas of pursuit, like drosophila genetics for example, a search for ‘PRE-1’ might be just as likely to return ‘photoreceptor regulatory element 1’. (Phys.org)—In the past, geneticists focused primarily on the evolution of genes in order to trace the relationships between species. More recently, genetic elements called SINEs (short interspersed elements) have emerged as a much better way to trace mammalian phylogeny, at least in the time since its massive radiation some 60 million years ago. That’s because the prolific SINE family evolved differently in every lineage to become widespread throughout the entire genome of each. But SINEs are more than just highly mobile markers, they have specific functions—functions which researchers are now decoding to understand not just how, but why they move about like they do. Credit: overlay by Eugene McCarthy Secondary structure of ALU RNAs. Credit: rna.berkeley.edu/translation.html In humans, the most familiar and abundant SINE is the Alu transposable element. Originally derived from a small cytoplasmic signal recognition conglomerate known as the 7SL RNA, Alu inserts have since propagated themselves to generate an extended family over a million strong representing 11% of our entire genome. With the exception of the Alu inserts in the primate superfamily (and one seemingly anomalous occurrence of the ‘B1’ SINE the rat) all other SINEs were believed to have been derived from tRNAs rather than the 7SL RNA.A recent paper published in the bioRxiv now suggests that another species—the pig—has a unique family of SINEs whose evolution has closely paralleled ours. This collaboration between researchers from China, and Firefly Bioworks Inc. here in the US, reports that the swine SINE known as PRE-1 (for porcine repeat element), also likely derives from 7SL RNA. This work potentially pushes back the divergence time of 7SL RNA products to 80-100 million years ago—a re-adjustment that would presumably ground the 7SL RNA diversification or hybridization events to a place before the so-called boreoeutherians diversified into Laurasiatheria and Euarchontoglires.

Kolkata: State government employees in the state have reasons to cheer with Chief Minister Mamata Banerjee announcing on Thursday that Dearness Allowance (DA) arrears of all government employees will be cleared by this month. The total DA of the employees will be 125 percent of their basic pay.”The DA arrears will be cleared by this month,” Banerjee said while addressing a public distribution programme at Ilambazar in Birbhum. The Chief Minister has kept her promise that she had made on June 19, 2018, when she had announced 25 percent additional Dearness Allowance (DA) for the state government employees with the merger of 10 percent interim relief. Also Read – Rain batters Kolkata, cripples normal lifeShe had also stated that it will be effective from January 2019 and the total DA of the employees will be 125 percent. It is 90 percent more than what it was till the end of the Left Front period. “We have to pay around Rs 48,000 crore every year to the Centre due to the huge debt burden left upon us by the erstwhile Left Front government, but the Chief Minister has taken up so many projects for the benefit of common people and is continuing to do so,” a senior official of the state government said. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe release of the DA will cost Rs 5,000 crore to the state’s exchequer every year. The DA recipients will also include teachers and non-teaching staff of educational institutions and employees of rural and urban local bodies. Sanket Chakraborty, general secretary of the State Steering Committee, congratulated the Chief Minister for providing the benefit. It may be mentioned that the gap between the Centre and Bengal with regards to DA had been 48 percent. Now, with the state government allocating 25 percent more DA, the difference will come down to 23 percent. The organisation of Trinamool Congress state government employees – Rajya Sarkari Karmachari Federation (RSKF), claimed that the state government’s move comes as a New Year gift for the employees. “We want the state government to bring out a fresh notification in this regard to clear any doubts or allegations from other unions,” said Manoj Chakraborty, convener of RSKF. It may be mentioned that Banerjee had addressed a programme of the RSKF in September 2017 at Nazrul Manch, where she had assured that the demand of the state government employees will be looked into with priority.
Adrian SarbuRomanian media tycoon Adrian Sârbu, the main shareholder in Mediafax Group and former president of Central European Media Enterprises (CME) was arrested and detained for 24 hours on Monday, accused of money laundering, embezzlement and tax fraud.According to local reports, the Romanian state prosecutor’s office has alleged that Mediafax Group set up a scheme involving the creation of dummy companies to avoid paying a tax bill amounting to about RON4 million (€910,000).Sârbu reportedly alleged that his arrest was politically motivated and intended to force the closure or sale of Mediafax’s properties to groups aligned with leading politicians.
