Verizon Wireless to start selling first 4G phone © 2011 PhysOrg.com (PhysOrg.com) — The United States Computer Emergency Readiness Team (U-CERT) has issued a warning to users of some HTC Android phones regarding a security vulnerability that has been found. The warning pertains to 802.1X WiFi user information and SSID data that can be viewed by rouge applications, taking advantage of a weakness in the OEM Android build of certain HTC phones.

HTC Desire HD Explore further Affected phones allow 802.1X WiFi information to be seen by applications that have access rights to WiFi information stored on the phone. This means errant applications could find their way to a stored SSID (Service Set Identifier – an identifier attached to the header of packets sent to a wide area network), login names as well as passwords. Also, should the phone connect to the Internet, identified information could then be sent back to those that created the application and who are looking for such information. And if the phone also connects to a corporate network, the vulnerability could lead to data being stolen.According to U-CERT, the phones at risk are:Desire HD (both “ace” and “spade” board revisions) – Versions FRG83D, GRI40Glacier – Version FRG83Droid Incredible – Version FRF91Thunderbolt 4G – Version FRG83DSensation Z710e – Version GRI40Sensation 4G – Version GRI40Desire S – Version GRI40EVO 3D – Version GRI40EVO 4G – Version GRI40HTC, a Taiwanese manufacturer of Smartphones, has had other security issues with their phones in just the past few months, and according to some unofficial sources, this particular vulnerability was discovered by Chris Hessing, a senior engineer with CloudPath Networks. Google and HTC were both apparently notified about the vulnerability last September after it was discovered. Since that time, both have been hard at creating a fix, which is now available to worried owners at HTC’s support site.Google has also reportedly performed a full scan on all of the applications available for download in the Market, and has found none that have tried to take advantage of the vulnerability, indicating that it’s possible nobody but Hessing and workers at HTC and Google were even aware of the vulnerability, which means despite the lapse by HTC, it’s likely no one was actually harmed by the problem.
Using 30nm class technology, Samsung develops industry’s first DDR4DRAM Explore further (Phys.org) — Micron Technology is polishing up its DDR4 memory modules, “sampling” the modules and getting feedback from major customers. The company plans to reach volume production later this year. In brief, Micron is getting ready to bring its DDR4 DRAM modules for market This means the computer industry can expect a new memory standard to make a difference across a range of computing devices, from enterprise computing to so called ultra-thins and tablets. Boise Idaho based Micron this week announced the first piece of its portfolio of DDR4-based modules as the 4-gigabit (Gb) DDR4 x8 part. The announcement said the complete portfolio of DDR4-based modules will include RDIMMs, LRDIMMs, 3DS, SODIMMs and UDIMMs (standard and ECC). Citation: To DDR3: Thanks for the memory but time for DDR4 (2012, May 10) retrieved 18 August 2019 from https://phys.org/news/2012-05-ddr3-memory-ddr4.html For the “soldered down space,” said Micron, the x8, x16, and x32 components will be available, with initial speeds up to 2400 megatransfers per second (MT/s), increasing to the JEDEC-defined 3200 MT/s. Observers assume that the DDR4 modules will first appear in enterprise machines with ultrathins and tablets up next. Advantages will be twofold; in terms of power savings and performance enhancements. Beyond Boise, one piece of unfinished business is still to be finalized, the JEDEC definition for DDR4. JEDEC stands for Joint Electron Devices Engineering Council and publication of the specification is awaited. JEDEC apparently intends to publish quite soon. According to JEDEC, “With publication forecasted for mid-2012, JEDEC DDR4 will represent a significant advancement in performance with reduced power usage as compared to previous generation technologies.“JEDEC said per-pin data rates, over time, will be 1.6 giga transfers per second to 3.2 giga transfers per second. With DDR3 exceeding its expected peak of 1.6 GT/s, it is likely that higher performance levels will be proposed for DDR4 in the future. Also planned in the new standard are a “pseudo open drain interface on the DQ bus, a geardown mode for 2667 Mhz data rates and beyond, bank group architecture, internally generated VrefDQ and improved training modes.” JEDEC will host a DDR4 Technical Workshop following the publication of the standard. Micron’s DDR4 technology was co-developed with Taiwan-based Nanya Technology. Founded in 1995, Nanya does research and development and design, as well as manufacturing, of DRAM products. In 2008, Nanya and Micron entered a joint technology development agreement. While the JEDEC publication will be complete midyear, Micron is wasting no time, with plans to reach volume production of its products in Q4 2012.Commenting on what to expect with DDR4, Nebojsa Novakovic, writing in VR-Zone, said DDR4 has better ways of handling parity and ECC errors than previous memory types, and it can provide recovery from both command and parity errors without crashing the system. Nonetheless, any real deployment will happen in 2014, he said, with AMD and Intel platform support of the new memory. © 2012 Phys.Org This document is subject to copyright.

Want to win in the NHL? Score first—but not until the third Explore further © 2014 Phys.org Citation: Study reveals a way to improve chances of winning at rock-paper-scissors (2014, May 2) retrieved 18 August 2019 from https://phys.org/news/2014-05-reveals-chances-rock-paper-scissors.html (Phys.org) —A trio of researchers at Zhejiang University in China has found a way for players to improve their odds of winning when playing the hand game rock-paper-scissors. In their paper they’ve uploaded to the preprint server arXiv, the researchers describe a field study they undertook with a large crowd of volunteers and how it revealed the secret. Scientists in many fields have studied game theory for thousands of years, some to gain military or social advantage, others to better understand human psychology. One game stands out, the hand game rock-paper-scissors, likely because of its simplicity, and because it can be used to make group decisions. Plus, it’s universal, requiring no language skills or preconceived social notions—therein lies its inherent beauty. Also, it’s supposed to be fair, with every player having a 1 in 3 chance of winning any given round. Prior research has suggested that such odds are the case, but now, it appears the experts may have been wrong. In this new effort, the team in China has found that due to human emotion and decision-making strategy, there is a way to better the odds when playing.To find it, the researchers recruited 300 volunteers from the university and divided them up into 60 groups and had them play the game. Winners were given different amounts of money to make sure that all players were trying to win. As the horde played, swapping teams periodically, the researchers filmed the action and afterwards, studied the tape. They found that players had a slight tendency to repeat a wining throw, and, to give up on a throw if they lost using it more than twice in a row. That meant, the researchers report, that in order to improve their chances of winning, all a player had to do was throw down a gesture that would beat the previous winner or throw down a gesture that would beat one of the other two gestures a prior loser had not just used.The researchers note that such predictable play is easy to explain—people naturally continue with a winning strategy and avoid those that don’t work. They call it the “win-stay, lose-shift” strategy, which because most of the people playing use it, results in any given player winning a third of the time—but, not if they know about the strategy used by their opponents, and their opponents don’t. Because the analysis came after the game playing, the researchers didn’t have the opportunity to test their theory that they’d found a winning strategy, but now that the cat’s out of the bag, it’s likely people all over the world will be testing it for them.

For the fundamental model system of Rock-Paper-Scissors (RPS) game, classic game theory of infinite rationality predicts the Nash equilibrium (NE) state with every player randomizing her choices to avoid being exploited, while evolutionary game theory of bounded rationality in general predicts persistent cyclic motions, especially for finite populations. However, as empirical studies on human subjects have been relatively sparse, it is still a controversial issue as to which theoretical framework is more appropriate to describe decision making of human subjects. Here we observe population-level cyclic motions in a laboratory experiment of the discrete-time iterated RPS game under the traditional random pairwise-matching protocol. The cycling direction and frequency are not sensitive to the payoff parameter a. This collective behavior contradicts with the NE theory but it is quantitatively explained by a microscopic model of win-lose-tie conditional response without any adjustable parameter. Our theoretical calculations reveal that this new strategy may offer higher payoffs to individual players in comparison with the NE mixed strategy, suggesting that high social efficiency is achievable through optimized conditional response.

More information: Heiner Saßmannshausen et al. Observation of Rydberg-Atom Macrodimers: Micrometer-Sized Diatomic Molecules, Physical Review Letters (2016). DOI: 10.1103/PhysRevLett.117.083401ABSTRACTLong-range metastable molecules consisting of two cesium atoms in high Rydberg states have been observed in an ultracold gas. A sequential three-photon two-color photoassociation scheme is employed to form these molecules in states, which correlate to np(n+1)s dissociation asymptotes. Spectral signatures of bound molecular states are clearly resolved at the positions of avoided crossings between long-range van der Waals potential curves. The experimental results are in agreement with simulations based on a detailed model of the long-range multipole-multipole interactions of Rydberg-atom pair states. We show that a full model is required to accurately predict the occurrence of bound Rydberg macrodimers. The macrodimers are distinguished from repulsive molecular states by their behavior with respect to spontaneous ionization and possible decay channels are discussed. Physicists have been interested in the properties of macromolecules for many years because they believe studying them will illuminate the fundamental properties of molecules in general. Prior research has shown that large, two-atom molecules should be possible if they were put into a Rydberg state—in which the outer electron exists in a high quantum state, allowing it to orbit farther than normal from the nucleus—and thus allowing for the creation of molecules thousands of times larger than conventional diatomic molecules such as H2. In this new effort, the researchers sought to test assumptions made about such molecules by actually building some. They did so by firing a laser at a pair of chilled cesium atoms to excite them and then by firing another laser with a smaller amount of energy to bring them into a Rydberg state. To make sure they had succeeded in making the large molecule, they used a device to detect that the ions that had been created during the process decayed to the lower Rydberg state, releasing the energy that had ionized the other atom. By actually creating the molecules, the pair were able to test many of the theories and assumptions about them made by others in the field.The team reports that their experiments confirm that some of the theories describing the behavior of macrodimer states were correct, but that others were not. Notably, their work has also advanced the understanding of macrodimers, which could help in a wide variety of research efforts. The researchers also note that the use of such molecules in quantum computers does seem feasible—if qubits were encoded in atoms in a Rydberg state, they note, the lack of force between them could present a more precise way to carry out operations than that used in other approaches. Distant partners. In this sketch, two cesium atoms in high Rydberg states form a weakly bound molecule about 1 micrometer across, comparable to the size of typical bacteria.

A candid conversation with Tarun Shienh unveils his human side as he exudes an urgent sense to do something for society. Tarun Shienh a hard core businessman also known as ‘The Real Estate Guru’ has always taken time out for the betterment of society, with the motive to do something for the underprivileged.He is also known for his passion to stand by any individual, who is in need. His charismatic personality makes him a one of the youngest and one of the most successful entrepreneurs in the real estate industry. He has reached this position by sheer hard work and dedication, which is what differentiates him from other entrepreneurs in this industry. Also Read – ‘Playing Jojo was emotionally exhausting’Shienh is a name to reckon with in the world of Indian real estate Industry and he has built up a team to help the society with any problems pertaining to real estate. The team solves queries of minimum 700 – 1000 people during a day, through emails.For these aggressive efforts and for providing an innovative platform to the society, he has been bestowed with the title of Real Estate Guru by the masses. His efforts are also recognised by some leading organisations and bodies. Also Read – Leslie doing new comedy special with NetflixBut his passion to help and work for the upliftment does not stop there. He wants to give back to the society. He is a true leader who is not just passionate about making real estate sector an organised sector but has taken steps forward for the upliftment of the unprivileged sections of the society. Recently, inspite of his busy schedule he visited a village near by Eta, where he discussed about their problems based on social and economic front, and promised them to take forward their issues. After spending some time with these children he realised that this was just a small step, with which he could bring smile on their faces but still there was a long road ahead to actually work for their upliftment. He is working very closely with NGO Lakshyam for the education of the underprivileged students, as he thoroughly believes that for the growth and prosperity of our country, these are the bricks, which have to be best laid. Over time he has supported many events to raise funds for the education of underprivileged and disabled students. Apart from this, he is also working closely with organisations to raise funds through charitable events for cancer patients.Talking to Millennium Post about his passion for charity Shienh says, ‘Being an entrepreneur and citizen of India, it is my first responsibility to help the society in all ways I can. I am sure our steps would help in providing better education and would give shelter to these young children.’ ‘I feel good when I do something for the needy or for the society, and I feel we all should join hands to work for the upliftment of these underprivileged sectors as a team…to make it sona ki chidiya again. And for this it is very important that we give education to each and every child of our country. I assure that I shall always stand beside such causes where we can facilitate these young kids with education and provide them with basic necessities for a better future,’ he adds. When asked about his title of ‘Real Estate Guru’, he laughed and said, ‘I am not that sort of Guru, its faith of my team and my customers that they always take my advice for investment and other queries related to industry perspective, that’s why I am a guru for them.’ When further asked what makes him different from other real estate entrepreneurs, he says that, ‘I am one of them, but it is just that I believe in transparency and direct dealing with customers providing them complete solutions. Our aim is to facilitate the customers with proper guidance to help them achieve their dream homes.’ Clearly Shienh has big plans ahead and the world needs to watch out!
