Intels new X79 chipset details leaked
(PhysOrg.com) — Today’s technology rumor has to do with Intel. A Chinese site, it.com.cn, has supposedly gotten its hand’s on a slide from Intel, a slide that outlines their next platform chipset. The slide even has a handy little road map on it. If the data on the slide, which has yet to be verified, turns out to be true, the X79, will be the successor to the popular X58 platform, which was launched about three years ago. The X79 is expected to seat four-core and six-core Sandy Bridge-E processors , and have significant upgrades to system memory. There will also be some changes in connectivity, but the details on this point are a bit sketchy.The X79 is also expected to feature an LGA 2011 socket. The PCI-E hub has been moved from the northbridge to the processor die, which would be similar to another Intel technology, the P67. The chipset has a DMI connection to the processor that is augmented with a PCI-Express 2.0 x4 link to the processor’s PCI-E hub. This would give the chipset a total bandwidth of 8GB/s. This bandwidth exists to support an integrated 10-port SATA 6Gbps controller with an additional four 3Gbps ports.

The chip is also designed to be overclocked, which means that this is meant to be a machine for serious enthusiasts.If the slide turns out to be genuine, the X79 will be arriving on the shelves of stores in the final quarter of 2011. Though again, one must remember that this is all conjecture based on a single slide. Do not plan your next upgrade based on this information. At least not until it is confirmed by the company. So, fact or fiction, you decide. Citation: Intel’s new X79 chipset details leaked (2011, March 31) retrieved 18 August 2019 from https://phys.org/news/2011-03-intel-x79-chipset-leaked.html

© 2012 Phys.org Explore further It was Einstein’s theory of relativity that got everyone believing that because the gravity of a black hole is so great, it’s not possible for anything to escape once it passes the event horizon, or point of no return. Witten says that while the theory is right, of course, it’s only right in a certain respect, because it violates the laws of thermodynamics, which say that if a reaction is possible then there is always supposed to be an opposite reaction. Applied to black holes, it suggests that if something can be consumed, then it ought to be able to be un-consumed as well. This whole idea is backed up by something Stephen Hawking came up with back in 1974, where he suggested that certain quantum particles should be able to escape a black hole, but that they would be too small for anyone to detect. He called the process Hawking radiation, and sure enough, no one has ever been able to detect them.Witten says that despite the seeming contradiction in the two views, there is a way to explain the differences; it’s about perception and point of view or looking at things in a macroscopic versus microscopic way and using the idea of entropy. Seen up close and personal, a black hole surely is capable of the occasional lapse, allowing a particle or even a whole atom to escape. But looking at the hugeness of a black hole across the vast distance of space, it definitely appears all consuming; always taking and never giving, to us appearing as if nothing, not even a photon could ever escape it’s clutches. That’s how you reconcile the two viewpoints. Color composite image of Centaurus A, revealing the lobes and jets emanating from the active galaxy’s central black hole.

More information: Quantum Mechanics of Black Holes, Science, 3 August 2012: Vol. 337 no. 6094 pp. 538-540. DOI: 10.1126/science.1221693ABSTRACTThe popular conception of black holes reflects the behavior of the massive black holes found by astronomers and described by classical general relativity. These objects swallow up whatever comes near and emit nothing. Physicists who have tried to understand the behavior of black holes from a quantum mechanical point of view, however, have arrived at quite a different picture. The difference is analogous to the difference between thermodynamics and statistical mechanics. The thermodynamic description is a good approximation for a macroscopic system, but statistical mechanics describes what one will see if one looks more closely. (Phys.org) — The journal Science is running a series of Reviews and Perspectives on the current state of knowledge and theories regarding black holes, written by leaders in the field. Some discuss what is believed to happen if two black holes collide, others describe what happens as binary stars are sucked up by black holes and whether intermediate size black holes really exist as new evidence is indicating. Yet another by doctoral fellow Rubens Reis, discusses a lucky break that allowed scientists to listen to the “cry” of the last bits of some matter just before being consumed by another black hole. But generating the most interest perhaps, is an article by Edward Witten of the Institute for Advanced Study in Princeton, New Jersey, a theoretical physicist, who argues that one of the most basic beliefs about black holes, namely, that nothing can ever escape it’s gravitational pull, is wrong, but only sort of.

DOI: 10.1098/rsos.140452AbstractThe adaptive significance of zebra stripes has thus far eluded understanding. Many explanations have been suggested, including social cohesion, thermoregulation, predation evasion and avoidance of biting flies. Identifying the associations between phenotypic and environmental factors is essential for testing these hypotheses and substantiating existing experimental evidence. Plains zebra striping pattern varies regionally, from heavy black and white striping over the entire body in some areas to reduced stripe coverage with thinner and lighter stripes in others. We examined how well 29 environmental variables predict the variation in stripe characteristics of plains zebra across their range in Africa. In contrast to recent findings, we found no evidence that striping may have evolved to escape predators or avoid biting flies. Instead, we found that temperature successfully predicts a substantial amount of the stripe pattern variation observed in plains zebra. As this association between striping and temperature may be indicative of multiple biological processes, we suggest that the selective agents driving zebra striping are probably multifarious and complex. People throughout history have wondered about the black and white stripes displayed by zebras, many asking themselves what caused the evolutionary changes that led to the unique design. Many ideas have been put forth, from suggestions that the stripes ward off flies, to ideas that they somehow confuse lions when they are in a herd. In this new effort, the researchers looked at many of the most prominent ideas and tested them for soundness. They also noted that there is considerable stripe variation among the zebras depending on where they live.In studying prior theories, the researchers found no evidence that any of them were sound—lions appeared to be unfazed by the stripes, for example, and only some types of biting flies appeared to be put off by the stripes. That led them to wonder if some other factor might be at play that might be revealed by stripe pattern variations between groups. To find out, they noted stripe characteristics on zebras at 16 different locations and compared them with 29 environmental factors such as heat, biting flies, predation, etc. In analyzing the data, the only correlation they could make was stripe pattern and heat—lower temperatures meant fewer or fainter stripes—higher temperatures meant more or darker stripes.The researchers do not know why temperature might have caused stripes to come about, but suggest it might have something to do with body heat regulation (the difference between the heat absorbing black and reflective white might create air movement) or that stripes evolved in zebras for a variety of reasons related to both heat and as a means of warding parasites or some other unknown problem. They believe more research needs to be done before the riddle can be truly solved. Scientists solve the riddle of zebras’ stripes © 2015 Phys.org

Kolkata: City dwellers on Thursday witnessed hot and uncomfortable weather, with many preferring to stay indoors during the afternoon hours. The sultry condition has been prevailing in the city and South Bengal districts for the past few days, as there was no rain. There was a drizzle in some parts of the city in the late afternoon hours on Thursday, but it failed to bring any respite to the people as it did not last too long.The regional meteorological centre in Alipore predicted that the hot and humid condition may continue to prevail in the next few days as well. However, there is a possibility of thundershower in some of the South Bengal districts, towards the evening hours in the next few days. Also Read – Heavy rain hits traffic, flightsIn view of the growing level of discomfort and high humidity level, the city doctors have issued some instructions on how people can avoid the sweltering heat during daytime. This time of the year generally does not see such a rise in the temperature but this year, there is an exception due to the heat wave coming from neighbouring states.A senior official of the weather office said that the weather condition may remain hot and humid during daytime, as a result of which people would perspire more, particularly in the afternoon. Many of those who came out on roads in the scorching summer heat on Thursday, wrapped their faces with handkerchiefs. The doctors have suggested that people, particularly those who are going out, must drink adequate amounts of water and other liquids. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedPeople have also been advised to carry umbrellas, to avoid the sunrays falling directly on their heads. People can also use sunglasses to get relief from the sun’s glare. The doctors also suggested that the city dwellers must wear cotton dresses, to get some relief from the heat. They have also advised against drinking soft drinks from shops and roadside stalls, while travelling in the sun. A large number of people were seen drinking lemon water or soda at the roadside stalls, while some others were found drinking soft drinks to comfort themselves in the sweltering heat. Many were also found standing in queues to have lassi from stalls in Dharmatala area, during daytime.Doctors also advised that if anyone is suffering from irritation or redness in the eyes, they should get medical help immediately, without wasting time. They also advised that anyone suffering from fever should be taken to nearby health care establishments without delay.
Kolkata: Want to savour the traditional fish items associated with the Durga Pujas of Sarbamangala Temple in Burdwan or Kanakdurga shrine at Chilkigarh in Jhargram in Kolkata? Here is your opportunity to relish Magur Macher Tok of Sarbamangala Temple or Shol Pora of Kanakdurga Shrine, thanks to State Fisheries Development Corporation (SFDC), which is leaving no stone unturned to serve such unique fish items in five of its restaurants.”Every year, we come up with something special for the fish loving Bengalis during Durga Puja. This year, we will be offering fish items of the old and traditional pujas of zamindars. We are already in talks with Sovabazar Rajbari, Sabarna Roy Choudhury Rajbari and some others for finalising such menus,” SFDC managing director Soumyajit Das said. Also Read – Rain batters Kolkata, cripples normal lifeThe bhogs cooked at the venues of some traditional pujas in the city will also be an integral part of the menu list.The SFDC has its restaurants at Nalban Food Park, Nabanna, Eco Park, Bidhan Sishu Udyan in Ultadanga and infront of Nicco Park. There will be a discount of 7 percent in the thali items and on the online delivery app during the Puja. Food items will be served in kansa (brass) or terracotta plates. It will be for the first time when people from this part of the state will be able to satiate their taste buds with Boroli fish during Durga Puja. Boroli variety is one of the most delicious fishes available in clear streams in the foothills of North Bengal. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIt was in April this year when as many as 23,000 Boroli fish seeds from Jalpaiguri in North Bengal was brought and are now being cultivated in three large waterbodies – Nalban Jheel adjacent to the Nalban Food Park, Goltala jheel near Chingrighata and Chotkhand jheel at Memari in East Burdwan. The SFDC will also experiment with two new varieties of fishes — Groupers and Indian Pompano — that they have cultivated in the last few months. The Indian Pompano, which belongs to the fast-growing Carangid family, has a great demand in Andhra Pradesh especially due to its good meat quality and nutritious value. It tastes more or less same as the Pomfret variety but will be available at a cheaper rate.The SFDC will set up stalls at the premises of 23 Durga Pujas in the city and offer a plethora of fish items. The Singhi Park, Hazra Park, Kalighat Milan Sangha, Hindustan Park in south Kolkata while Jagat Mukherjee Park, Sovabazar, Tala Sarbojonin, Nalin Sarkar Street will be some of the spots for SFDC’s puja stalls.
The loving bond that India and Bangladesh share is no secret to the world. Even though they are separated by a geographical border, India, especially West Bengal, shares a deep bond with Bangladesh.The Art Acre foundation organised for an art workshop recently, where 10 eminent artists from Bangladesh arrived at Arts Acre and created artworks along with 6 eminent artists who had sent their works as they could not be present in person. The contribution of Bangladeshi artists in the development of Bengal Modern Art as a whole is very significant. Along with Rabindranath Tagore, Abanindranath Tagore, Nandalal Bose and others, artists like Zainul Abedin and Quamrul Hassan can be considered pioneers of the Bengal Contemporary Art Movement. Also Read – ‘Playing Jojo was emotionally exhausting’The Arts Acre Museum of Bengal Modern Art is the largest museum dedicated to modern Bangla art. The museum hopes to devote a permanent gallery to the works of eminent artists from Bangladesh. Arts Acre believes that it would be a great opportunity and platform for artists from Bangladesh to showcase and express their work in the City of Joy as well as the country. While, it will add an extra dimension to an already well stocked museum, it also hopes to add a new perspective and enable access to a previously untapped source of art. The works were displayed in a special ‘Bangladesh Gallery’ in the museum.

In addition to the workshop, every evening during the festival, cultural programs were organised, where well known performers, both from Bangladesh and Kolkata enthralled everyone with their performances. The vocal artists from Bangladesh who performed at the event were Subir Nandi, Rumana Islam Khan, Suchitra Rani Sutradhar, Shemonti Monjari, Rocsana Akter Rupsa and Nishita Barua. Choreographer Sudarshan from Kolkata presented his Modern Dance piece ‘Imagining Images’, while singer Iman Chakraborty mesmerised the audience with her electric performance. On the evening of June 3, the special ‘Bangladesh Gallery’ was inaugurated by Asaduzzaman Noor, Minister of Cultural Affairs, Govt. of the People’s Republic of Bangladesh, in the presence of Ganesh Haloi, Bibhash Chakraborty, Gautam Deb, Minister of Tourism, Govt. of West Bengal, Bratya Basu, Minister of Information and Technology, Govt. of West Bengal and many other eminent personalities from across the city.The new ‘Bangladesh Gallery’ was lauded for its beautiful artwork the impressive infrastructure of the Arts Acre Foundation.
The findings showed that obese study participants maintained activation in the midbrain, one of the body’s most potent reward centres. However, this brain activity dropped among lean participants while continuing in their obese counterparts.“Before or after the meal, they’re just as excited about eating. It seems they have an instinctive drive to keep eating,” said Nancy Puzziferri, Assistant Professor at the University of Texas. Further, while the appeal of pictured food dropped by 15 per cent for lean women after they ate, the severely obese women showed only a 4 per cent decline. Also Read – ‘Playing Jojo was emotionally exhausting’“Lean women when full will either stop eating or just sample a food they crave. It’s just not a level playing field – it’s harder for some people to maintain a healthy weight than others,” Puzziferri explained. For the study, published recently in the journal ‘Obesity,’ the team compared attitudes and the brain activity of 15 severely obese women (those with a body mass index greater than 35) and 15 lean women (those with a BMI under 25). Their brain activity was measured using functional magnetic resonance imaging (fMRI). After fasting for nine hours, they were asked to rate their level of hunger or fullness, and then given a brain scan as they viewed pictures of food. Again, after eating, the participants went through another battery of hunger/fullness ratings and fMRI scans while being exposed to pictures of food. The obese women showed a sustained “hungry” brain activation, even though they reported the same increase in satiation as their lean counterparts, the researchers has concluded.
Surfing the internet in classrooms may lead to poorer test scores, even among the most intelligent and motivated students, a new study has warned.Researchers at Michigan State University (MSU) in the US studied laptop use in an introductory psychology course and found the average time spent browsing the web for non-class-related purposes was 37 minutes.Students spent the most time on social media, reading emails, shopping for items such as clothes and watching videos. Also Read – Add new books to your shelfResearchers found that their academic performance suffered. Internet use was a significant predictor of students’ final exam score even when their intelligence and motivation were taken into account, said Susan Ravizza, associate professor of psychology at MSU and lead author of the study. “The detrimental relationship associated with non-academic internet use raises questions about the policy of encouraging students to bring their laptops to class when they are unnecessary for class use,” Ravizza said. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe research was conducted in a one-hour, 50-minute lecture course with 507 students taught by Kimberly Fenn, MSU associate professor of psychology and study co-author.In all, 127 students agreed to participate in the study, which involved logging onto a proxy server when the students went online. Of those participants, 83 checked into the proxy server in more than half of the 15 course sessions during the semester and were included in the final analysis. Intelligence was measured by ACT scores. Motivation to succeed in class was measured by an online survey sent to each participant when the semester was over. Interestingly, using the internet for class purposes did not help students’ test scores.“There were no internet-based assignments in this course, which means that most of the ‘academic use’ was downloading lecture slides in order to follow along or take notes,” Ravizza said.Previous research has shown that taking notes on a laptop is not as beneficial for learning as writing notes by hand.”Once students crack their laptop open, it is probably tempting to do other sorts of internet-based tasks that are not class-relevant,” she added.
India bleeds creativity. Be it in any field- art, culture, music, dance or theatre. We are also home to numerous varied techniques of creativity that has been passed down from generation to generation but in these modern times and in the hustle bustle of life we don’t pay attention to the symphony of life. SPIC MACAY (Society for the Promotion of Indian Classical Music And Culture Amongst Youth), an organisation made for this purpose recently held a conference to address the crowd about their work, their future plans to uphold the art forms of the past and details for the Memorial Concert for Vidhushi Kishori Amonkar by Padma Vibhushan awardee Vidhushi Girija Devi.
