More information: UEFIVia: BBC News (PhysOrg.com) — The 25 year old PC BIOS will soon be replaced by UEFI (unified extensible firmware interface) that will enable PC’s to boot up in a matter of seconds. In 2011 we will start seeing UEFI dominate new PC’s, according to BBC News. UEFI is designed to be much more flexible than the old PC BIOS that dates back to some of the first IBM PC’s since 1979. The BIOS has not changed much in the past 25 years and is one of the main reasons why a PC’s boot-up time is over 25 seconds.The original EFI specification was developed by Intel but has now evolved into a standard which is now known as UEFI. The UEFI forum, which is a non-profit corporation, is responsible for the management and promotion of the specification. Their goal is to replace the 25 year old BIOS that’s responsible for slow boot-ups.Mark Doran, head of the UEFI Forum, is quoted as saying: “With UEFI we’re getting it under a handful of seconds. In terms of boot speed, we’re not at instant-on yet but it is already a lot better than conventional BIOS can manage, and we’re getting closer to that every day.”Some PC manufactures have already started using UEFI and system administrators who oversee thousands of PC and servers have already seen the benefits of swapping old-fashioned Bios for UEFI. © 2010 PhysOrg.com UEFI is an interface that takes care of handing over the pre-boot environment to the operating system.

Credit: IEEE Spectrum Citation: World’s most powerful MRI gets set to come online (2013, October 24) retrieved 18 August 2019 from https://phys.org/news/2013-10-world-powerful-mri-online.html (Phys.org) —The most powerful MRI machine in the world is nearing completion. The new instrument will be able to generate 11.75 Tesla, a field strong enough to lift 60 metric tons. Squeezing out those last few Tesla (the previous record for field strength was around 9.4) requires extraordinary precision in the design and manufacture of the superconductor magnets at its core. As a recent article in IEEE Spectrum reports, fields of this magnitude are stronger than those used in the Large Hadron Collider which famously discovered the Higgs boson. As a research tool, a machine like this would allow the brain to be imaged in unprecedented detail—a voxel size of .1mm as compared to 1 mm previously. But as medical device makers struggle to design implants that won’t move, heat up or otherwise fail in fields of that strength, the opportunity for new discovery in the brain, will by guided also by a few new challenges to be overcome. More information: spectrum.ieee.org/biomedical/i … rful-mri-takes-shapewww.nature.com/news/brain-deco … eading-minds-1.13989 MRI machines normally image the relatively strong signals associated with the nuclei of hydrogen. With higher field strengths it is possible to image signals from sodium or potassium, the ions that are also among the most mobile in carrying the charge associated with spikes in neurons. An area of 0.1mm still might have over 1000 neurons so this technology is not going to be imaging neuron activity individually. It may however, provide recent efforts to decode the private imagery associated with our inner thoughts and dreams with much greater accuracy than current methods. While a recent paper in Nature contains an air of optimism regarding the progress of the decoding algorithms used in these kinds of studies, cautionary tales regarding the interpretations of the results still abound.The 270 million dollar scanner project, know as INUMAC (Imaging of Neuro disease Using high-field MR And Contrastophores), has been in development for the last seven years. Delivery was taken this summer of some 200 km of superconducting niobium-titanium wire. When cooled with superfluid helium to 1.8 Kelvins, this wire will be able to carry 1500 amps. The key to making a magnet that won’t melt or vibrate itself apart, is a new winding design that permits the helium to get where it needs to for cooling, and also provides for winding alignment to micrometer precision. Today electromagnetic devices, like precision servomotors, are no longer wound willy-nilly like a random spool of yarn, but rather put together so that each turn is in the proper place. The idea is that entire electromagnet hums coherently as a whole and creates a uniform field. A more expensive wire material, niobium-tin, would in theory carry enough current at the same diameter to create fields up to 20 Tesla, but it is much more brittle than niobium-titanium and difficult to wind.Pushing field strengths ever higher raises a few concerns. Implant manufacturers, like Medtronic, have a tough job to do to insure the safety of their devices inside magnet bores. One indicator of the gravity of the situation, is that they have taken to naming their devices according to their tolerance of fields strong enough to turn gas cylinders in adjacent rooms into guided missiles. Their SureScan pacemaker comes with guarantee of MRI compatibility—at least up to certain fields strengths, and their spinal cord neurostimuluators, commonly used to subvert chronic pain, come with documentation that doesn’t shy away from some hard-core physics. For example, an MRI system generates three kinds of fields, each of which have different potential for interaction with a device. The static fields are present at all times around the magnet, while the three orthogonal gradient fields kick in only during the scan. A pulsed RF field is also present during the scan, and is created by a variety of different methods. We might note here that when an airplane takes-off or lands, powering down your devices in the face of the unknown is only a nuisance. Powering down an implant, if it is advised, may have more inconvenient consequences.A final cautionary tale before leaping in to one of these new machines, is that the effects of double-digit field strength on the tissues of the body itself are not completely understood. Computer models and simulations will be invaluable in setting guidelines here, but ultimately the proof is in the pudding. Physical tests will be needed, both as reality check for the things missed by the model, and also to help indicate areas perhaps where the models might be too restrictive.

Kolkata: Mystery shrouds the death of a housewife at Bansdroni in the southern fringes of the city, who died after she complained of illness and was taken to Bijoygarh Hospital by her in-laws on Thursday night. The deceased Payel Chakraborty (32), a resident of Shyamnagar in North 24-Parganas, was married to Mriganka Roy in January 2017. The deceased’s father Swapan Chakraborty alleged that his daughter was subjected to physical and mental torture at her in-laws’ house after a few months of her marriage. Also Read – Heavy rain hits traffic, flightsHer husband, brother-in-law and mother-in-law used to torture her, according to Chakraborty who had lodged a complaint with Bansdroni police station, alleging that her daughter has been murdered.”My daughter had video called me at around 8.30 pm at night. She was absolutely fine. An hour later, my son-in-law called me up, informing that my daughter had fallen sick and had been admitted at Bijoygarh Hospital. As we were preparing to go there, he again called up and told me that Payel has expired. She was tortured and that ultimately resulted in her death,” the deceased’s mother Balaka Chakraborty alleged. Payel had told her mother that she would come on the occasion of Jamai Sasthi, which is scheduled in a week’s time and had told her to purchase a dress for her husband. The police have detained Payel’s husband on the basis of the complaint, but her brother-in-law Mridul Roy is absconding. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedPayel was married to Mriganka Roy in January 2017, after contact was established through a matrimonial site. After they were introduced through the site, they had met each other on more than one occasion and both had consented to the marriage. The deceased’s husband is a teacher at an English medium school in New Town.”We are investigating the matter on the basis of a complaint lodged by the deceased’s father. We are talking to some of the neighbours and other members of the deceased’s in-laws for the sake of probe,” a senior officer of Bansdroni police station said.
Team India cricketer Amit Mishra was on Tuesday arrested here in connection with a complaint filed by a woman for allegedly physically assaulting and abusing her in a hotel room here last month, and later released on bail. Mishra was arrested after nearly three hours of questioning at Ashoknagar police station and released on bail later, DCP (Central) Sandeep Patil said. Complying with a summons issued by the Bengaluru police last week after he was booked for the charges based on the complaint by the woman, Mishra, who was given seven days time, appeared before them.
Kolkata: A Metro rake ran from Belgachia till Kavi Subhash on Friday morning with one of its door open, after it failed to close down due to some technical snag.An RPF personnel stood guard at the door to prevent any untoward incident. According to sources in the Metro, the snag developed after a broken portion of a pen cap somehow got stuck in the door channel.The snag came to the notice of the motorman at around 11 am in the morning, after the train reached Belgachia Station. The front door of the first compartment refused to close as the train was about to depart. Also Read – Rain batters Kolkata, cripples normal lifeAn RPF personnel on duty at the platform noticed a plastic object sticking out of the door channel. As he tried to remove the same, it broke with a portion of it coming off in his hands, with the rest still remaining stuck in the door channel.Within a few minutes, the decision was taken by the railway police in coordination with the Metro authorities that the rake should continue to run. An RPF constable stood guard at the door with his hands on either side of the door, as the train continued its journey. There was a change of duty at Chadni Chowk Metro Station and this time, two RPF personnel stood guard at the door till the journey ended at Kavi Subhash. The motorman tried to close the door in between as the train stopped at stations, but failed to do so.”We could have emptied the rake when the snag took place. This could have inconvenienced the passengers. So we decided on keeping the train running after ensuring the security of the passengers. When the train reached Kavi Subhash, it was sidelined to the car shed,” said a spokesperson of Kolkata Metro.The portion of the broken pen cap was removed and after proper testing of the door, it was found to be working perfectly.
Kolkata: The state government in collaboration with Kolkata Port Trust (KoPT) has been able to prevent the oil spill from the vessel MV SSL Kolkata that had emerged as a threat to the ecosystem of the Sunderbans after it caught fire in the Bay of Bengal on the night of June 13.”More than 90 percent of the oil in the ship has been successfully extracted and the remaining work will be completed within 10 days’ time,” a relieved senior official of the state Forest department who has been supervising the entire operation said. Also Read – Rain batters Kolkata, cripples normal lifeApart from being a threat to the ecology and the river and sea creatures, if the oil had actually spilt over, it could have mingled with the water and travelled to human habitat areas of Gosaba and others. “So extracting oil out of the ill-fated vessel was our top priority,” the official added. There was 400 tonne of furnace oil loaded in the affected ship. A drill was made in the oil tanks of the affected ship and after extraction, oil was transferred through a pipeline to another vessel that was stationed at a safe distance from the affected ship. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIt may be mentioned that the state Forest department has provided all sorts of logistics to the Singapore-based company that was roped in by KoPT for extracting oil from the affected ship. The District Magistrate of South 24-Parganas has been acting as the nodal officer for the entire operation and the district administration had also mobilised people from the adjoining villages who helped employees from the shipping company in emptying the oil barrels. State Chief Secretary Malay De organised meetings time to time with the concerned agencies like KoPT Indian Coast Guard, Indian Airforce and top officials of the Forest department to keep a stock of the progress. Initially, all the stakeholders had laid emphasis on transfer of oil with the threat of spilling looming large. Hence, the efforts to tow the ship to the bank was overlooked. “Now, the ship had sunk so deep into the sea soil that it cannot be moved from the spot. So the remains of the ship will gradually sink into the water. This will result in water pollution but the effect will be much less than the oil spill,” a senior official in the district administration said.
Kolkata: The state Co-Operation department will set up 2,631 Customer Service Points (CSP), particularly in areas lacking branches of nationalised banks to render services to the rural population.”Chief Minister Mamata Banerjee has instructed us to take bank services to the areas which lack nationalised and private bank branches. We have set a target of coming up with CSPs in 2,631 Gram Panchayat (GP) areas across the state. Around 250 such CSPs have already come up,” state Co-Operation minister Arup Roy said. Also Read – Rain batters Kolkata, cripples normal lifeSources in the department said the CSPs are being set up in the offices of the co-operative societies and will have all the facilities of a banking service branch. There will be Rs an investment of 15 lakh for each unit and the total cost of the project has been earmarked at Rs 300 crore. The employees of the co-operative societies will be trained for rendering services to the users. It may be mentioned that there are around 710 villages in the state which do not have banks. The state Co-Operation department has already set up 50 banks to cater to these villages and is gradually setting up more and more branches. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe state government is also focusing upon recovering NPAs in the co-operative banks. “We are now offering loan at a rate of 2 percent to the farmers bringing it down from 4 percent. The state government is offering subsidies to the banks in this regard so that they can offer loan at a low percentage,” an official said. The minister mentioned his department has set a target of providing farmer’s loan to the tune of Rs 7,000 crore in the 2018-19 fiscal up from Rs 5200 crore that was allocated in 2017-18. “The loan for Self-Help Groups has been set at Rs 1,200 crore in 2018-19 financial year up from Rs 1,000 crore in the last fiscal,” Roy said. The department will organise Co-Operative fair from November 19 to 22 at Netaji Indoor Stadium. State Finance and Industry minister Amit Mitra will inaugurate the fair.
Your Facebook status updates, ‘likes’ and even photos could help researchers better understand mental health disorders, a new study says. Social networks may even be used in future to treat mental illness, particularly among young people, the researchers said.“Facebook is hugely popular and could provide us with a wealth of data to improve our knowledge of mental health disorders such as depression and schizophrenia,” said the study’s lead-author Becky Inkster from University of Cambridge. Also Read – Add new books to your shelfOver a billion people worldwide use Facebook daily – one in seven of the global population – and social media use is increasing at three times the rate of other internet use. “Its reach is particularly broad, too, stretching across the digital divide to traditionally hard-to-reach groups including homeless youth, immigrants, people with mental health problems, and seniors,” Inkster noted. The researchers believe that Facebook might be used to help improve the detection of mental health factors. Also Read – Over 2 hours screen time daily will make your kids impulsiveFacebook data tends to be more reliable than offline self-reported information, while still reflecting an individual’s offline behaviours, study co-author Michal Kosinski from Stanford Graduate School of Business in the US added.It also enables researchers to measure content that is difficult to assess offline, such as conversation intensity, and to reach sample sizes previously unobtainable. Status updates, shares and likes can provide a wealth of information about users, the researchers noted in the study published in the journal Lancet Psychiatry. “Facebook relationships may help those with reduced self-esteem and provide companionship for individuals who are socially isolated,” Inkster said.“We know that socially isolated adolescents are more likely to suffer from depression and suicidal thoughts, so these online stepping stones could encourage patients to reform offline social connections,” she added.These online – potentially leading to offline – social connections can provide support for vulnerable individuals such as homeless youth, a population at increased risk of mental health problems. Research has shown that this support is associated with a reduction in their alcohol intake and a decrease in depression-like symptoms. Unlike virtual patient communities, an advantage of using social networking sites, especially Facebook, is that people naturally use them in their daily lives, which addresses concerns about the limited duration of participation in virtual communities, the study said.
