The main advantage of having six states is that it would increase the memory density while avoiding the problems inherent in miniaturization. Currently the primary strategy for increasing memory density is to miniaturize each memory element so that more of them can fit on a chip. However, at these small scales, the memory elements are so close together that they begin to interfere with each other’s states. The new design can avoid this problem, and also offers other advantages.”Going from two to six states would triple the density under certain conditions (for example, maintaining the lateral scale of the bit),” Klein said. “In addition, other advantages are also expected. The cost of the memory would probably decrease significantly, and when such bits are incorporated in a magnetic memory array, we may witness other benefits such as increased reading speeds.”The researchers expect that it may be possible to design patterns with even more magnetic states. For example, their simulations show that a pattern of four crossing ellipses would yield a memory element with eight magnetic memory states. “We intend to further increase the number of magnetic states and explore the limits of such an extrapolation,” Klein said. “In addition, we would like to progress towards fabricating a prototype that will help us convince the magnetic memory industry to make a shift towards multi-level magnetic memory.” Realizing the six-state magnetic element does not require any significant increase in complexity, such as adding layers, but rather involves simply structuring one of the magnetic layers differently—specifically, arranging the magnetic film into a pattern of three crossing ellipses. In the middle region where all three ellipses overlap, the researchers found that there are six different stable magnetic orientations. The orientations are parallel to the long axis of each ellipse, and can run in two opposite directions. If such a pattern with six magnetic orientations can be controlled and incorporated in a magnetic memory element, then the number of memory states can be increased from two to six. The researchers showed that such control is possible by using a technique called spin-orbit torque switching, which uses spin-polarized electric current to switch between magnetic states. This demonstration shows that the spin-orbit torques can write data onto the magnetic structure, showing the potential for using the structure as a memory element. The researchers, Yevgeniy Telepinsky et al., from Bar-Ilan University in Israel and New York University in the US, have published a paper on the new magnetic structure in a recent issue of Applied Physics Letters.This isn’t the first time that researchers have designed memory cells with more than two states, or bits. The best-known example is multi-level flash memory cells, which can store up to four bits per cell. While multi-level flash cells have advantages such as a higher density and lower cost, they also suffer intrinsic drawbacks such as lower writing speeds and higher power consumption.The new six-state memory element presented here is different because it is magnetic, whereas flash memory is electronic. Although electronic memories are currently the most commonly used type of memory, various types of magnetic random access memory (MRAM) are being actively researched due to advantages in low power consumption, fast operation, and long lifetime.”Our proposal paves the way for enjoying the benefits of multi-level cells in MRAM, making it even more attractive for applications,” Lior Klein, a physics professor at Bar-Ilan University and one of the study’s lead authors, told Phys.org. “Furthermore, since MRAM is different in its nature from flash, there is no reason that it should suffer from the drawbacks of multi-level-cell flash memory.” By arranging magnetic film into a pattern of three crossing ellipses, researchers demonstrated six magnetic configurations are possible in the overlapping region.

Also Read – Rain batters Kolkata, cripples normal lifeA total of 7 persons including Binay Tamang, Mandip Sharma, Amod Mukhia, Jyoti Kumar Rai, Dewraj Dewan and John Rai has been discharged owing to lack of evidence. “However, the charge-sheet stated that investigation is still open and that the CID can file a supplementary charge-sheet later on,” added Prasad. The accused have been charged under various sections of the Indian Penal Code including Sections 307 (attempt to murder); 120B (criminal conspiracy), along with different sections of the West Bengal Maintenance of Public Order Act and Prevention of Damage to Public Property Act. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe Gorkha Janmukti Morcha (GJM) under the leadership of Gurung had locked horns with the security forces on June 8, 2017. The GJM party was on agitation in the Hills. Police reports claim more than 45 security force personnel were injured in the clash. A police booth was set on fire. Around 15 police vehicles were torched along with a state government Bus. Army was deployed in Darjeeling, Ghoom and Kurseong to control the situation. On that day, the GJM had taken out rallies and staged a sit-in demonstration a short distance away from Raj Bhawan where the Cabinet meeting was taking place. Later, the demonstration turned violent and clashes ensued. The GJM in turn had alleged that many of their supporters were also injured in the clashes. Police had lodged a suo moto FIR and a case had been started at Darjeeling Sadar Police Station on June 9. The case was handed over to the CID on June 29, 2017. On September 6, arrest warrants were issued against Gurung, Asha Gurung, Roshan Giri and 5 front rung GJM leaders. The CJM Court had ordered them to appear in court and surrender in November 2017. Bimal Gurung, Asha Gurung, Roshan Giri and others failed to appear on the designated date. On March 28, 2018, the CID had prayed these absconders be declared as offenders and their movable and immovable properties be attached. The court then issued an order of attachment of Gurung’s house. It was attached on August 2. Following this, properties of other leaders including Prakash Gurung were also attached as per the court order. Prior to this, in June, Bimal Gurung and Roshan Giri’s names were struck off from the electoral rolls in Darjeeling.
Kolkata: With India’s fighter pilot Abhinandan Varthaman returning to his homeland on Friday night after being in Pakistan’s custody for two days, Chief Minister Mamata Banerjee welcomed his return.”Welcome home #AbhinandanVarthaman Welcome home sweet home,” Banerjee wrote on her Twitter handle. Banerjee on Thursday accused the Narendra Modi government of seeking political mileage over the air strike carried out by the Indian Air Force in Balakot, stressing on the fact that the Centre is yet to divulge the truth about the terrorists allegedly killed in the strike. Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose”The people of India have a right to know what exactly happened during the air strike. The Centre must allow our forces to speak the truth. They should also come clean on the number of terrorists claimed to have been killed during the air strike,” Banerjee had maintained. While speaking to the media at Nabanna on Thursday, the CM hit out at the Modi government, saying: “Ahead of the forthcoming elections, the Centre is keen on deriving political mileage from the air strike that has been conducted by our Air Force. The jawans defend our borders and we all hold them in high esteem. But politicising the whole issue only to satisfy one’s political interest is condemnable.”
When children her age would only think of their upcoming board exams, Niharika Prakash – a disciple of world-renowned Odissi dancer Ranjana Gauhar – is leaving no opportunity to showcase her craft on the international stage. An eleventh-grade student of Modern School, Barakhamba Road was introduced to the art of Odissi dance at a tender age of seven, and since then Odissi has become an integral part of Niharika’s growth. With time she has learned to strike a balance between academics and her passion for dance. Also Read – Add new books to your shelf”I began dancing when I was seven. Back then, there wasn’t much academic pressure, but with time the work burden increased. Studies are hard, but I can confidently say that dance has helped me to perform better academically. It has taught me the importance of discipline and hard work,” says Prakash, adding, “There is no half-heartedness, there is no room for complacence for a dancer. Dance demands you give it your all, which is what I have tried to do. I wouldn’t have done any better at studies if I didn’t dance. Over the years, I have learned to prioritize, to multi task, to work hard and persist. I still spend 3 hours a day in my dance class and yet manage to get 90% and above.” Also Read – Over 2 hours screen time daily will make your kids impulsiveThis dedicated pupil knows there is no substitute for hard work. The young dancer – along with Utsav Dance Troupe – has performed at multiple prestigious events, including the Konark Dance Festival, the Khajuraho Dance Festival, Sangeet Natak Akademy (Imphal and Delhi), Kurukshetra Mahotsav, and regaled audiences in Spain and Argentina. On being asked about the most memorable experiences in her career, Prakash narrates the time when she was selected to represent her school (Raghubir Singh Junior Modern School) in an inter-school exchange program held in Boardilla Del Monte, Madrid, Spain. (In 2012). “I was ten and barely knew how to dress myself up. I had to muster up the courage to perform my first solo in front of hundreds of little Spaniards. It was a cold morning and the entire school of Teresa Berganza in Boardilla Del Monte was out in the court to watch me perform. I was so anxious. The music played, I began to dance, bare feet on the cold concrete ground of the school field. The audience was so appreciative of the performance that the children imitated my eye gestures and hand movements for days.”Every classical dance form has its own specialty and each person views a dance form differently. Niharika was more drawn to Odissi than any other style of dancing. “Odissi appealed to me as a confluence of grace and strength. A dance form with delicate eye and neck movements, supple torso movements yet rigorous footwork,” she says. Recalling how her grandmother and mother have always taken a keen interest in Indian culture, Niharika feels a tad nostalgic. “When I turned three, I tagged along for dance recitals and cultural events and learned to appreciate Indian art. This is how it all started,” she says.
Kolkata: A fish trader was shot dead by a few miscreants in Howrah on the wee hours of Friday.According to sources, the deceased fish trader identified as Tarak Bhuniya, used to sell fish at Parbati Bazar near Bose Para in Byantra. He used to buy fish from the Howrah wholesale fish market. Like other days, Bhuniya was going to the Howrah fish market to buy fish on his bicycle, on Friday at around 4 am. When he was crossing the Bankim Setu over Howrah railway station, a few miscreants surrounded him and tried to snatch away the bag containing money.

Two bullets penetrated his abdomen and chest and he fell on the road, bleeding profusely. Hearing his screams, some local residents ran to his rescue. Seeing them, the miscreants fled from the spot. Bhuniya was rushed to Howrah District Hospital, where he revealed his identity. However, a few minutes later, he succumbed to his injuries at the hospital. The hospital authorities immediately informed Golabari police station. Also Read – Lightning kills 8, injures 16 in stateSources informed that there is a CCTV camera installed near the murder spot. In the footage collected from it, the miscreants were seen firing at Bhuniya. Police claimed that the killers have been identified and will be behind bars soon. However, till Friday night no one has been arrested. Though police are claiming that the miscreants have been identified, the motive behind the murder is still not clear. Sleuths suspect that Bhuniya might have had some business rivalry with someone, or it could have been a case of snatching money, where the miscreants shot Bhuniya because they were resisted. Sleuths are also checking to know if he has any family problem as police came to know that he had got married twice and both of Bhuniya’s wives are alive.
