The four processors, which will be based on the new Krait architecture, will be called MSM8270, MSM8930, MSM8960, and APQ8064 Snapdragon chips. The processors, which are expected to sample this year and to begin showing up in the works of Qualcomm’s partner companies products by the end of this year. The processors are expected to be shown off in single, dual and quad-core CPUs that can be clocked at speeds of up to 2.5GHz.So, how much real difference will these next generation processors give to the end user? Well, according to the slides that were leaked, the next generation processors are expected to give machines five times greater performance than the existing line of Snapdragon chips. The newer chips will, at the same time, consume significantly less power than the current generation of Snapdragon chips, about 75% less power. That means that these processors could be of use in mobile systems, where power use becomes a serious issue for battery life.The details get a little sketchy when you begin to talk about graphics. While we do know that these processors will rely on a next-gen Adreno GPU, but we do not know which one. No specific mention has been made of the most likely candidate, the Adreno 3xx. Others have speculated that it may be the Adreno 22x. Either way, the company claims that the system will be capable of delivering both console quality gaming and by able to support 1080p displays.

“Skype first deployed ‘mega-supernodes’ to the cloud to improve reliability of the Skype software and service in December 2010,” he said. The nodes were deployed at Skype’s data centers, in third-party infrastructure such as Amazon’s EC2, and most recently in Microsoft’s data-centers and cloud.The move was made to improve platform reliability and “to increase the speed with which we can react to problems,” he added.Gillett said reports of changes to facilitate law enforcement’s access to instant messages were false too. He acknowledged that some messages are stored temporarily on Skype/Microsoft servers for immediate or later delivery to a user, “to provide for the delivery and synchronization of instant messages across multiple devices, and in order to manage the delivery of messages between clients situated behind some firewalls which prevent direct connections between clients.”Skype does make an exception to cooperate with law enforcement, he said, “if a law enforcement entity follows the appropriate procedures and we are asked to access messages stored temporarily on our servers,” and he said that will happen “only if legally required and technically feasible.”Meanwhile, the China-only version of Skype remains a glaring exception to privacy. The China-only version is provided locally through Skype’s joint venture partner operating “tom.com” which contains a “chat filter” in order to comply with local laws. The Chinese government monitors communications in and out of the country. TOM Online, like other communications service providers in China has an obligation to comply in order to operate in China.Skype traditionally has been credited with its use of strong encryption and complex peer-to-peer network connections as a safeguard against interceptions. What fed on recent alarm and speculation were reflections on the supernode move in the light of how Microsoft had filed in 2009, before the acquisition of Skype, an application to the U.S. Patent and Trademark Office, which was later published in 2011, describing “recording agents” to legally intercept VoIP phone calls. Microsoft’s application noted that “Sometimes, a government or one of its agencies may need to monitor communications between telephone users. To do this with POTS, after obtaining the appropriate legal permission, a recording device may be placed at a central office associated with a selected telephone number. Electrical signals corresponding to sound to and from the telephones at the selected telephone number may be monitored and transformed into sound. This sound may then be recorded by the recording device without the telephone users being aware of the recording. With new Voice over Internet Protocol (VoIP) and other communication technology, the POTS model for recording communications does not work.” This “Legal Intercept” patent application discussed an idea for how communications on VoIP networks can be silently recorded.Skype serves 250 million active users each month and supported 115 billion minutes of person to person live communications in the last quarter alone, according to numbers cited by Gillett on the Skype blog. The reports have suggested that Skype infrastructure upgrades may make it easier to hand over users’ chat data to eager legal agencies wanting access to conversations over the Skype service. The reports were largely based on a recent addition of supernodes in the data centers of Skype’s new corporate parent, Microsoft. Skype moved its supernodes into Microsoft’s data centers for the purpose of reliability, not to please legal surveillance agents, assured the company in its statements.Earlier this month, Mark Gillett, Skype’s corporate vice president of product engineering and operations, described all claims that Skype was bending its policy rules as false. In contact with ExtremeTech, Gillett said any changes in infrastructure were to improve user experiences.“As part of our ongoing commitment to continually improve the Skype user experience, we developed supernodes which can be located on dedicated servers within secure datacenters. This has not changed the underlying nature of Skype’s peer-to-peer (P2P) architecture, in which supernodes simply allow users to find one another (calls do not pass through supernodes). We believe this approach has immediate performance, scalability and availability benefits for the hundreds of millions of users that make up the Skype community.”More recently, he decided to pen a detailed explanation of what Skype has done and why on Skype’s own, The Big Blog. He was concerned that reports could mislead the Skype community about how Skype handles user security and privacy.“It has been suggested that Skype made changes in its architecture at the behest of Microsoft in order to provide law enforcement with greater access to our users’ communications,” he said, which he repeated as false.Regarding the supernodes, he said that even before Microsoft came into the picture for acquisition of Skype, the latter was already in the process of moving supernodes to cloud servers.

With windows wired, sensors carry occupancy, light and temperature signals. The windows can adjust to varied conditions. Manual adjustments can be made through a wall unit, web interface, or smartphone. The wall switch allows for the selection of dynamic tinting which may range from “clear” down to “dark tint” with intermediate steps in between. View says the glass is extremely durable. Play Credit: View, Inc. View’s glass system is promoted also on the appeal of less costs over time and less complexity. Unwanted heat and glare, according to View, have often resulted in design compromises. where architects and homebuilders have felt compelled to add blinds, external shading structures, and large heating, ventilation, and air conditioning (HVAC) systems. Costs are shaved when there is no need for blinds but as importantly costs are realized when energy bills are shaved. The company claims that in a typical commercial installation, annual HVAC and lighting energy consumption is reduced by 20 percent while HVAC peak load is reduced by 25 percent.The longer-term savings may resonate with building designers and architects who are always interested in smart glass solutions for windows and skylights. View invites their interest in solving problems where “generous glazing” may provide plenty of natural light but also heat and glare. “They also commonly require expensive shading solutions and large, dedicated HVAC systems,” according to View. The View Dynamic Glass can adapt the tint level accordingly. The W Hotel in San Francisco is to showcase View’s glass in its lobby.This week another company, SAGE Electrochromics of Faribault, Minnesota, made their smart windows announcement of having shown “the world’s first dynamic glass window system that enables variable tint zones within a single pane of electrochromic glass.” The company’s Glass Control System can be programmed to work automatically with light sensors, or manually using push-button controls. Their “SageGlass” will ship next year, they said, when a new manufacturing plant starts commercial production.View has manufacturing facilities in Olive Branch, Mississippi. Researchers develop new reversible, green window technology © 2012 Phys.org (Phys.org)—Another step forward in the electrochromic glass trade is this week’s announcement by the Milpitas, California,- company View that its self-tinting window solution, called View Dynamic Glass, is ready for deployment. View’s team has also announced that the glass system is about to go on public display for the first time at the Greenbuild International Conference and Expo in San Francisco, running this week. Everyone likes to sit near a window until it gets too hot or bright, reminds View’s leaders, and therein lies the appeal of a newer breed of “smart” windows that adjusts to surrounding conditions.

Are Magnetically Levitating ‘Sky Pods’ the Future of Travel? © 2013 Phys.org Explore further (Phys.org) —Milton Keynes, a town north of London, has announced that it will be deploying 100 driverless pods (officially known as ULTra PRT transport pods) as a public transportation system. A similar system has been running for two years at Heathrow airport. The plan is to have the system up and running by 2015, with a full rollout by 2017. The move marks the first time that self-driving vehicles will be allowed to run on public roads in that country. This document is subject to copyright.

Passengers can call (and pay £2 per trip) for a pod using their smartphone. The pods travel using rubber wheels on a special roadway, not a track, between curbs that help in guidance. Each pod is computer driven by independent onboard systems, though humans (passengers) can take over if there is a problem. Each can hold up to two people and their luggage and travels just 12mph. Plans call for the pods to carry passengers between the downtown area, the business district and the train station.The pods are expected to be cleaner, quieter and less expensive than the current bus system—each pod has a battery powered electric motor and is charged at various stations between routes. The project is expected to cost £65 million over the next five years and is part of the British government’s initiative to support green technologies. Milton Keynes was chosen as a test site due to its proximity to London, its unusually wide roads and its willingness to embrace new technology. The move has been the next step after the successful implementation of the system first installed at Heathrow airport in 2011 where 4km of track has been dedicated to run 21 of the pods—all without major issues. Officials note the pods have sensors meant to ensure the safety of both passengers and pedestrians.It is widely believed that if the pods prove to be successful (and safe) in Milton Keynes that the day will come when they will no longer be restricted to their own private lanes, opening the door to general driverless public transportation—a move that may ultimately result in driverless passenger vehicles being sold to the public at large.

The content is provided for information purposes only. As scientists continue the quest to fully understand the genome, new tools are constantly being developed. One avenue of research involves delving into the differences between individual cells that are almost identical—embryonic cells, for example—each has its own unique genome,even in the same organism. Prior research has led to tools that amplify differences, or variances between cells, which not only helps to better understand how genomes work, but which has practical applications. One such tool that has been developed and used to study and measure genetic variance among individual cells is MALBAC—it is used for in vitro fertilization to screen embryos. But as the researchers also note, it is subject to allele dropout, which limits its ability to call single-nucleotide variations. In this new effort, the researchers have found a way to improve the technique—the improved version is called Linear Amplification via Transposon Insertion (LIANTI), and they claim it has kilobase resolution.LIANTI works by fragmenting the genetic material in a cell using a transposon the team designed. A transposon is a bit of DNA that is able to alter its position in a genome. It had a 19 base-pair double-stranded transposase binding spot and a single-stranded T7 promoter loop. The transposon carried with it a promoter which was a part of DNA that begins the process of transcription. The promoter was used to amplify the downstream DNA, allowing for the creation of a library that could be sequenced. Initial indications suggested the new technique would outperform other methods.The researchers tested their technique by exposing human cells to ultraviolet light and then measuring their variances—they report their approach covered 97 percent of the genome, which was significantly better than other methods. (Phys.org)—A team of researchers working at Harvard University has developed a new whole-genome amplification method that outperforms other methods currently being used. In their paper published in the journal Science, the team describes their technique and how well it performed when used to measure single-nucleotide variations in a human cell after exposure to ultraviolet radiation.

Single-cell whole-genome analyses by Linear Amplification via Transposon Insertion (LIANTI), Science (2017). DOI: 10.1126/science.aak9787AbstractSingle-cell genomics is important for biology and medicine. However, current whole-genome amplification (WGA) methods are limited by low accuracy of copy-number variation (CNV) detection and low amplification fidelity. Here we report an improved single-cell WGA method, Linear Amplification via Transposon Insertion (LIANTI), which outperforms existing methods, enabling micro-CNV detection with kilobase resolution. This allowed direct observation of stochastic firing of DNA replication origins, which differs from cell to cell. We also show that the predominant cytosine-to-thymine mutations observed in single-cell genomics often arise from the artifact of cytosine deamination upon cell lysis. However, identifying single-nucleotide variations (SNVs) can be accomplished by sequencing kindred cells. We determined the spectrum of SNVs in a single human cell after ultraviolet radiation, revealing their nonrandom genome-wide distribution. Explore further © 2017 Phys.org Journal information: Science

In the world of paleoecology, little has been known about the historical record of ecosystems in the West African highlands, especially with regard to glacial cycles amidst a shifting climate and their effects on species diversity. It has long been a subject of debate whether stability or instability of tropical forests is responsible for the high levels of species richness found there. Regarding the glacial intervals, the researchers note that Afro-alpine grasslands dominated for a short period at MIS 5 (~82 ka ago), and for a long period between MIS 4 to MIS 2 from 72 to 15.5 ka ago. They found lowland steppes and desert biomes predominating during the glacial maxima, with a pronounced effect at MIS 2 with “the near-absence of forest elements.” The data at MIS 2 represented the driest episode within the 90 ka core record.Unlike the case in East Africa, there is no record indicating the presence of actual glacier formations in the equatorial West African highlands. In East Africa, glaciers pushed the upper treeline lower. Pollen data do suggest that Afromontane trees in the highlands were in fact more widely distributed at lower altitudes than they are today. As an example of this, they cite the Afromontane tree Olea capensis, which has been able to successfully migrate to lower altitudes during the last glacial maximum only to return to higher altitudes during warmer periods. The record of one species cannot be considered exemplary of the Afromontane biome as a whole, however.In order to understand the dynamics of the Afromontane forest with regard to expansion/contraction and migration over time, the researchers sought to define its upper and lower limits. The upper limit is hence defined as the proportion of Afro-alpine grasslands in relation to Afromontane forests, whereas the lower limit is defined as the ratio of lower-level montane forest to tropical seasonal forest. Interestingly, the supposedly stable Afromontane forests proved to be anything but. As Anne-Marie Lezine and her fellow researchers state “The most remarkable result of our study is the ecological instability of the Afromontane forest belts compared with the relative stability of lowland tropical seasonal forest over the past 90 ka.” The Afromontane forest at its upper limit proved to be most vulnerable to a changing climate, whereas its lower limit was defined by relatively stable equatorial forests. These findings cast doubt on the widely held view that such tropical lowland forests were indeed unstable and in flux, and only survived amidst pockets of refugia.Unlike the case of Afromontane forests in East Africa, where long term ecological stability over the past 40 ka is thought to have contributed to its currently high level of biodiversity, vegetation diversity levels in the highlands of Cameroon have proven to be highly variable over time, an observation in line with the instability of Afromontane forests shown here. While minimum levels of diversity tracked the lowest position of the upper Afromontane treeline between 35 and 26 ka, higher than present levels of pollen richness occurred during forest expansion phases.”The increase in diversity estimates started well before the LGM [Last Glacial Maximum] and accelerated from 20 ka ago onward. The highest diversity was then reached during the Younger Dryas dry event (~12.9 to 11.7 ka ago) (25), during a phase of major ecological disturbance and not during the following early Holocene phase of forest stability at 10 to 9 ka ago.” All of this has led the study authors to conclude “that Afromontane forests of Cameroon are neither ‘glacial’ nor ‘contemporary’ refugia. Glacial climates did not lead to forest disappearance but had a major impact on the upper treeline, which shifted dramatically, revealing the sensitivity of the upper montane biomes to climate change.” One theory holds that stable and species-rich “refugia,” or enclaves, of tropical forest survived periods of climatic instability within larger areas of grassland-dominated landscape. Pollen data to support this theory are ambiguous however, as they come mainly from marine core samples that represent a large region of vegetation zones and do not resolve well to a local level. Continental records and genetic data are similarly inconclusive with regard to stability or instability of this ecosystem. Equatorial mountains, on the other hand, are believed to have been stable moist habitat throughout many glacial episodes, acting as “glacial refugia” to support richly biodiverse montane forests up to the present day. An alternative theory holds that these forests only recently stabilized and became refugia during the Holocene epoch beginning around 20 ka (20,000 years ago). To better understand the ecological history of Afromontane forests, an international team of researchers examined pollen data from two core samples recovered from Lake Bambili, a system of two high-altitude volcanic crater basins in Cameroon. Lake Bambili, at 2273 meters (~ 7500 feet) above sea level, lies within an Afromontane forest belt which is bounded at its upper limits by an Afro-alpine grassland, and at its lower limits by submontane forests and savannas, which in turn form the transition to tropical rain forests.The first core sample, B1, retrieved from the upper basin of Lake Bambili, provided a continuous pollen sequence dating back to the beginning of the Holocene. The second core, B2, which lacked tephra horizons—layers of volcanic ash—to more accurately confirm its radiocarbon chronology, was correlated with adjacent marine records recovered offshore from Cameroon. This core sequence provided a continuous pollen record dating back 88.9 ka to the Last Interglacial period, and in particular provided a picture of three distinct forest phases separated by phases where grasslands predominated during glacial periods. The researchers characterize the contraction and expansion of Afromontane forests amidst the temperature backgrounds of Marine Isotope Stages (MIS). Each of the three forest phases was quite distinct in terms of biome composition. The first phase, during MIS 5—from 82.6 ka to 72 ka ago—is characterized by lower-level montane forest and upper-level Afromontane forest. The second forest development phase, a more moderate phase during MIS 3, from 53 to 38 ka, also included lower-level montane forest and upper-level Afromontane forest, but with lower proportions of woody taxa and a more narrow altitudinal range. The third phase, occurring from 10 to 3.3 ka ago, contained lower-level montane forest as well as tropical seasonal forest. More information: Anne-Marie Lézine et al.

File your response by next date of hearing,” the bench said. The High Court was hearing a PIL filed by advocate Swati Aggarwal, seeking directions to allow banking customers to make unlimited number of transactions free of any charge on own bank ATMs. Also Read – Lanka launches ambitious tourism programme to woo Indian touristsAccording to the plea, the guidelines came into force from November 1 and have already been implemented by several banks, including State Bank of India, the largest bank in India, said the plea. It claimed that the guidelines were issued at the behest of a few banks and IBA, which had approached RBI seeking changes in the extant instructions regarding free transactions at other banks’ ATMs. The plea contended that levying of charges was highly “arbitrary and unjustified” besides being “discriminatory and against good banking practices and reforms and a backward move”. It also said that the RBI guidelines were against international practices in relation to use of own bank ATMs followed across the world. “In almost all modern economies of the world, there is no cap on the number of transactions one can make on own bank ATM and unlimited number of transactions remain free of charge on their own bank ATMs,” it said.
