New NEC Technology Isolates Viruses At the Core

first_imgNEC Multi-Core CPU Explore further Bacteria live on our eyeballs—and understanding their role could help treat common eye diseases NEC has developed a new technique for running software in separate processes on each core of a multi-core CPU whereby it stops viruses before they spread throughout the Internet-connected device, according to Digital World Tokyo.NEC has not named the new technology that is designed to spot the virus in any of the software processes and immediately isolate and shut down that core. The technology allows the device to continue operating while the infected core is shut down, thus preventing the infection from spreading into the system. Utilizing this method of isolation and disabling the mal-functioning core then allows anti-virus software to tackle the problem. In addition, the technique allows the user to hold the virus in place while anti-virus updates are created and then downloaded from the Internet. The technology can be applied to cell phones, cars, and potentially computers. NEC may be encouraging manufacturers to buy their multi-core chip due to its design with the capability to segregate, isolate and treat sophisticated viruses. As noted by most security companies and software engineers the current and future range of potential harm created by rampant and uncontrollable viruses is a world wide concern. A technology that allows commercial, governmental and private users to stop the virus dead in its tracks without creating a pandemic spread of sophisticated viruses throughout systems is a innovation worth noting. NEC has developed a new technology for spotting, isolating and stopping viruses at the core level of its multi-core CPU. Thus, the system keeps running, while the infected core is disabled while a fix is developed and then downloaded from the Internet.

Intel unveils Rosepoint—CPU and WiFi on same chip

first_img A wireless future where everything that computes is connected Explore further (Phys.org)—Justin Rattner, Chief Technology Officer at Intel, got up on stage at a recent Developer Forum sponsored by the company and talked about some of the communications technology it’s working on; chiefly a chip it calls Rosepoint, a System on a Chip (SoC) that has a dual core Atom processor along with a WiFi radio transceiver. It’s the culmination of ten years of research he told the audience, in trying to integrate digital processing with analog radio signals. © 2012 Phys.org The presentation by Rattner made clear a major problem computer hardware makers are facing; as chips are made ever smaller, faster and less energy intensive, radio communications devices have lagged. Making them smaller causes them to work less well because they are analog based. They also tend to cause interference with other digital parts which has forced hardware makers to keep the different types of components separated. For Intel, this has been a problem that needed to be overcome as they made clear in their presentation that they believe the day will come when virtually every computer enabled device will need to talk wirelessly, with every other. What needed to happen, they said, was for radio to go all digital and that’s what they’ve done. Rosepoint is, a “Moore’s Law Radio” they say, a radio that can be made smaller without loss of signal strength.To make a digital radio, Intel engineers had to go back to the very basics of how radio technology works and reinvent new ways to build each part; digital phase modulators, power amps, frequency synthesizers, etc. The last, one, the synthesizer, is the part that deals with interference, canceling it on the fly and preventing it from interfering with Atom digital processors.None of the Intel speakers gave any indication as to when Rosepoint might begin showing up in actual products, but by showcasing the new technology, Intel has demonstrated their willingness to invest heavily in technology aimed mostly at handheld devices, an area where Intel has not been nearly as dominant as they have been in desktop and laptop computers.The company also gave a few details about other projects it’s working on, such as a way to allow laptops or ultrabooks to seem as always “on” as smartphones, a next generation wireless standard they call WiGig, and biometrics technology that hopefully will offer consumers a better way to protect themselves from those trying to gain access to their personal data, e.g. devices that read palm signatures rather than rely on passwords.center_img Rosepoint chip combines CPU with WiFi.

Researchers devise means to combine scanning tunneling microscopy and infrared spectroscopy

first_img Journal information: Physical Review Letters (Phys.org) —A team of researchers at the University of California with members also from Lawrence Berkeley National Laboratory and Stanford University has succeeded in combining tunneling microscopy and infrared spectroscopy to gain a better understanding of how molecules behave when they stick to a surface. In their paper published in the journal Physical Review Letters, the team describes how they used a custom built laser to allow for performing infrared spectroscopy with scanning tunneling microscopy without heating its tip. Explore further Citation: Researchers devise means to combine scanning tunneling microscopy and infrared spectroscopy (2013, September 24) retrieved 18 August 2019 from https://phys.org/news/2013-09-combine-scanning-tunneling-microscopy-infrared.html Remote sensing of molecular vibrations with a scanning tunneling microscope (STM) tip. Pechenezhskiy et al. illuminate molecules on a gold substrate by a tunable infrared laser. When the illumination is resonant with a particular vibrational mode, the excitation is transferred to the substrate. This, in turn, causes the surface to shake, which is detected by variations in the tunneling current through the STM tip. As the laser frequency is changed, the STM signal maps out the vibrational spectrum.

Rev. Lett. 111, 126101 (2013). DOI: 10.1103/PhysRevLett.111.126101AbstractWe have developed a new scanning-tunneling-microscopy–based spectroscopy technique to characterize infrared (IR) absorption of submonolayers of molecules on conducting crystals. The technique employs a scanning tunneling microscope as a precise detector to measure the expansion of a molecule-decorated crystal that is irradiated by IR light from a tunable laser source. Using this technique, we obtain the IR absorption spectra of [121]tetramantane and [123]tetramantane on Au(111). Significant differences between the IR spectra for these two isomers show the power of this new technique to differentiate chemical structures even when single-molecule-resolved scanning tunneling microscopy (STM) images look quite similar. Furthermore, the new technique was found to yield significantly better spectral resolution than STM-based inelastic electron tunneling spectroscopy, and to allow determination of optical absorption cross sections. Compared to IR spectroscopy of bulk tetramantane powders, infrared scanning tunneling microscopy (IRSTM) spectra reveal narrower and blueshifted vibrational peaks for an ordered tetramantane adlayer. Differences between bulk and surface tetramantane vibrational spectra are explained via molecule-molecule interactions. This document is subject to copyright.

Researchers use Raman spectroscopy and STM to allow chemical mapping of molecules to 1nm resolution Scanning tunneling microscopy is able to gather information at the atomic level of a material by making use of a tiny tip that is placed near a material and then measuring the amount of current that passes between the tip and the material. Using this method, researchers can gather information about individual molecules and atoms, but cannot distinguish between them. Infrared spectroscopy gathers information about a material via a laser focused on a sample—infrared light is bounced off the material and differences in frequencies reveal which types of molecule are present. Unfortunately, the technique is not precise enough to single out individual atoms that make up the molecules. In this new effort, the researchers set out to combine the two technologies to allow for gaining the benefits of both, while negating their individual drawbacks.To overcome problems with laser heat impacting the scanning tip, the researchers used a custom built laser that was capable of irradiating a gold surface upon which tetramantane or tetramantane crystals had been deposited. The scanning tip was placed far enough away from the surface to avoid being impacted. When the laser was fired, the team found that the current between the tip and the surface increased when its frequency was set to that of one of the crystals’ absorption frequencies. By measuring the increase, the researchers were able to determine which crystal had been absorbed into the gold substrate. This meant that the team had combined the best attributes of both types of scanning devices.The only downside the team reported was that the scanner was only able to use the average signal from a set group of molecules rather than single molecules—they plan to continue their work with the combined devices with the hope of refining the process to allow for both analyzing and identifying molecules at the nanoscale. By comparing such molecules in a free group with those adhering to a surface, the researchers hope to gain new insight into how molecules behave when attaching themselves to a surface.last_img read more

Dads play pivotal role

first_imgFathers play a surprisingly large role in their child’s development – from language and cognitive growth in toddlerhood to social skills in fifth grade, a new study has found. The findings published in two academic journals Early Childhood Research Quarterly and Infant and Child Development, provided evidences of the father’s importance to a child’s outcomes and reinforces the idea that early childhood programmes should focus on the whole family, including mother and father alike.  Also Read – ‘Playing Jojo was emotionally exhausting’The study found that fathers’ parenting-related stress had a harmful effect on their child’s cognitive and language development when the children were two-to-three years old even when the mothers’ influences were taken into account. Fathers’ influence also had a larger effect on boys’ language than girls’ language. Parental stress and mental health issues affect how parents interact with their children and subsequently, childhood development, revealed the study. “There’s this whole idea that grew out of past research that dads really don’t have direct effects on their kids. But here we show that fathers really do have a direct effect on kids, both in the short term and long term,” said Claire Vallotton, Associate Professor, Michigan State University. Using data from about 730 families the researchers studied the effects of parents’ stress and mental health problems such as depression on their children. Fathers’ mental health had a long-term impact, leading to differences in child’s social skills (such as self-control and cooperation) when the children reached fifth grade.  In fact, fathers’ depression symptoms when children were toddlers were more influential on child’s later social skills than were mothers’ symptoms, suggested the research.last_img read more

New Town Lawyers death Wife denies charges

first_imgKolkata: Though police claimed that Anindita Pal Dey has admitted to have killed Calcutta High Court lawyer Rajat Kumar Dey, she herself has denied the charges made against her.On Sunday, she denied the police statement and said she has no hands in Rajat’s murder. She was remanded to police custody after the sleuths told the court about her contradictory and misleading statements. Sources informed that in the course of investigation it was revealed that she had no plan for murdering Rajat. All of those things happened in the hit of the moment. Anindita alleged that Rajat used to torture her both mentally and physically. During altercations Rajat used to threaten her saying he would commit suicide. Also Read – Rain batters Kolkata, cripples normal lifeAccording to the sources, during interrogation in police custody, Anindita informed the sleuths that on November 24 the same situation had occurred and when Rajat told her that he would commit suicide, Anindita lost self-control and used some sort of wire to strangulate Rajat. Though the sleuths could not identify any other motive, some police officers still do not want to believe Anindita’s statements. Several question arose after she made her statements such as — Has Anindita murdered Rajat by strangulation by herself or was there someone else who had helped her in committing the crime? Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedDuring the last few days of enquiry, the sleuths came to know about a third person, a doctor by profession, who might have some connection with the murder. But police have refused to make any comments on this. Another question which arises is that why did she shift her son and the pet dog to her paternal home if she did not have plans to murder Rajat? “The probe is on. Anindita is being interrogated thoroughly. Several questions are cropping up which need to be answered by her. It could be an unplanned murder,” said a senior police official from the Bidhannagar Police. As Anindita was misleading the investigating officers from the very beginning of the case, the sleuths are not holding her statements to be true. On the contrary, police officers are waiting to see if Anindita changes her statement again.last_img read more

GJM calls for Gorkha unity to tackle BJPs conspiracy

first_imgDarjeeling: The Gorkha Janmukti Morcha (GJM) has called for Gorkha unity to thwart BJP’s alleged conspiracy to displace the Gorkhas from this region. This comes in the wake of BJP president Amit Shah’s threat to implement the National Register of Citizens (NRC) in Bengal, if voted to power.Addressing a BJP election campaign rally in Alipurduar on Friday, Shah had stated: “We will implement the National Register of Citizens (NRC) in Bengal to identify and throw out each and every infiltrator from the state. We want to assure each and every Hindu refugee that no one has to leave the country. All of you will have a place to live in India with respect. This is our commitment.” Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataShah’s statement subsequently ruffled a few feathers. “There is a conspiracy hatched by the BJP against the Gorkhas. We have to unite against this. Amit Shah’s statement has come as a shock to the Darjeeling Hill people, where more than 80% of the population do not have land rights. It is a tell-tale sign of uncertain future for the hill people without land rights, if BJP is voted to power. People will be asked to provide land documents. There will be a fixed cut-off year. Gorkhas will then be dubbed illegal immigrants. They will replicate what they have done in Assam. Thousands of Gorkhas have been labelled as ‘D voters’ or ‘Doubtful voters’, despite having lived in Assam for generations,” stated Binay Tamang, president, GJM. Also Read – Lightning kills 8, injures 16 in stateThe GJM president stated that Shah’s statement comes at a time when the sitting BJP MP of Darjeeling SS Ahluwalia alleged that the Gorkhas living in Darjeeling were migrants from Nepal. “Also, the recent revelation from the RTI query on the government’s stand on granting of tribal status to the 11 Gorkha communities is indeed worrying. The RTI reply had stated that the granting of tribal status would only increase influx from Nepal,” Tamang said.last_img read more
