Citation: Doubts continue on claim to have solved P vs NP mathematical question (2010, August 17) retrieved 18 August 2019 from https://phys.org/news/2010-08-p-np-mathematical.html One of the most complex mathematical problems in the world is proving either that P ≠ NP or P=NP, a riddle that was first formulated in 1971 by mathematicians Leonid Levin and Stephen Cook. The question was one of seven millennium problems set by the Clay Mathematical Institute (CMI) in Cambridge, Massachusetts as being among the most difficult to solve. P vs. NP — The most notorious problem in theoretical computer science remains open More information: www.hpl.hp.com/personal/Vinay_ … r/Papers/pnp12pt.pdfcenter_img Explore further Vinay Deolalikar, a computer scientist from Hewlett-Packard’s research arm based in Palo Alto, California, claims to have solved the problem and stands to win $1 million if his proof is accepted.P refers to problems with solutions that are easy to find, in other words P is a class of problems for which an answer can be found in polynomial time. NP refers to problems with solutions that are almost impossible to find, but easy to verify, or in other words a class of problems for which an answer can be verified in polynomial time. The Clay Mathematical Institute offers the following problem to illustrate NP: you have a list of 400 university students to be accommodated but there is only room in the dormitory for 100 students. The Dean has provided a list of pairs of incompatible students who cannot be on the final list. This is an NP-problem because it is extremely difficult to go through all possible combinations to come up with a list, but very easy to verify once a list is obtained. According to CMI the number of possible combinations is greater than the number of atoms in the universe.If P ≠ NP some complex problems, such as the one above, could never be solved efficiently and there are serious limits on what computers will be able to accomplish in the future, whereas if P = NP every such problem would have a polynomial time solution. Mr Deolalikar writes that this would have profound implications for applications such as cryptography and on the question of whether or not human creativity could be automated.Among those skeptical of Deolalikar’s claim is Scott Aaronson, assistant professor of electrical engineering and computer science at the Massachusetts Institute of Technology (MIT), who said on his blog that he will personally add $200,000 to the prize, even though he can ill afford it, and he has not read Deolalikar’s entire paper. He said if the proof was correct it would change his life so dramatically that “having to pay $200,000 will be the least of it.” He later also gave his reasons for being so confident in MIT’s technology review.Another skeptic is Professor Richard Lipton at Georgia Tech College of Computing, who has been working on the P vs NP problem for three decades.Deolalikar’s paper is available online, and is being peer-reviewed by computer scientists. To be considered for the million dollar prize the paper must be published in an approved mathematics publication and must also retain general acceptance by mathematicians two years after the proof is published. © 2010 PhysOrg.comlast_img read more

Eurocopter demonstrates new emergency backup electric motor for helicopters

The content is provided for information purposes only. Citation: Eurocopter demonstrates new emergency backup electric motor for helicopters (2011, October 14) retrieved 18 August 2019 from https://phys.org/news/2011-10-eurocopter-emergency-backup-electric-motor.html © 2011 PhysOrg.com Explore further Eurocopter X3: The world’s fastest copter (PhysOrg.com) — Normally, when a helicopter loses power in flight due to engine failure, the pilot reverts to using a technique called autorotation to avoid crashing. What happens is the rotors keep spinning automatically due to the air rushing past as the aircraft descends, which prevents the aircraft from picking up speed as it descends, eventually leading to a reasonably safe landing. The problem though, is that controlling such a descent is quite difficult due to the lack of power adjustments to the angle of the rotors, which can lead to pitching. In a sense it’s much like the difference between regular and power brakes. The pilot is forced to rely on a lot of muscle power. To make things easier for pilots, and thus safer for all concerned, Eurocopter, the biggest maker of helicopters in the world, has come up with a way to allow a pilot to more easily maintain control of the rotors while descending and landing using an electric motor add-on. Traditionally, the most difficult parts of using the autorotation technique, is the beginning of the event and the landing. The beginning is difficult because more often than not the helicopter is leaning towards its destination to head forward in that direction, thus the aircraft needs to be leveled off. Landing is always the most difficult part of flying a helicopter because of the many tiny adjustments that need to be made just as the aircraft touches the ground; doing so with no engine power is far more complicated due to the inability to alter the speed of descent and the difficulty in changing the rotor angle. Plus, the pilot only gets one shot.To help in both cases, the engineers at Eurocopter have developed an electric motor and battery system that can be used in the event of engine failure. It appears that the backup motor doesn’t actually make the rotors go around, but instead allows the pilot to effortlessly adjust the rotor angle, which allows for much easier stabilization both during the initial switchover and during landing.In the demonstration, a AS350 helicopter outfitted with the new motor was able to land very nearly as easily as it would have using its normal gas engine.Eurocopter is a global company with main offices in France, Germany and Spain. It makes both commercial and military helicopters. As part of its announcement, the company said it plans to implement the new technology in all of its aircraft and will continue to look into using what it’s learned with the electric motor to help in the development of true hybrid helicopter technology to help cut fuel consumption.last_img read more

Increased deaths from lung disease tied to more fires in Southeast Asia

first_img © 2012 Phys.org Journal information: Nature Climate Change (Phys.org) — Sometimes in science, it’s a matter of thinking about things in new ways. That’s what a team of US and British researchers have found after studying the numbers of fires that are set intentionally in Southeast Asia to clear forests during El Niño events as compared to so-called normal years, and the incidence of lung disease leading to deaths in the region. After studying a decade’s worth of satellite images, the team, as they describe in their paper published in Nature Climate Change, found what appears to be a correlation between El Niño events and increased deaths due to the pollutants in smoke from fires.

The content is provided for information purposes only. In the western world, people are used to associating an El Niño event with warmer waters in the Pacific Ocean, leading to altered weather patterns across North America. But the same events lead to cooler waters in the eastern Pacific, most specifically around Indonesia and Southeast Asia. That leads to less rainfall during the annual monsoon season, which allows for more burning of forests to produce more crop land. And burning more forests produces more smoke with the associated pollutants, which the team has found, might conceivably be adding up to 15,000 deaths per event.To find these correlations, the team studied satellite images taken during the decade 1997 to 2006 to discern how many fires were being set and how much pollution they were generating. They then plugged that information into chemistry models to see how much of which pollutants would be generated by such fires. Because a strong El Niño occurred in 1997, the team was able to follow the chain reaction of events. They found that shortly after the event began, the number of fires picked up and fine particulates in the atmosphere increased to over 300 times the amount the World Health Organization has established as a safe benchmark, for a period of 200 days. They found that levels of ozone were also elevated. They compared this with data from the opposite type of event, a La Niña that occurred in 2000, bringing more than normal rain to the area and a reduction in the number of fires. Particulates from the fires that year were 98% lower than in 1997.In studying the satellite images the team was also able to follow the track the pollutants took and found they were concentrated mostly around Indonesia and Malaysia. They then estimated the number of people that would die from the inhalation of the particulates based on the population of the area where the pollutants traveled and found they likely amount to between six and fourteen thousand deaths per event. Ozone from the fires likely add another two to six thousand deaths.The one upside to the study, the authors suggest is that because the fires are man-made, they could be stopped given the right set of circumstances.center_img More information: El Niño and health risks from landscape fire emissions in southeast Asia, Nature Climate Change (2012) doi:10.1038/nclimate1658AbstractEmissions from landscape fires affect both climate and air quality. Here, we combine satellite-derived fire estimates and atmospheric modelling to quantify health effects from fire emissions in southeast Asia from 1997 to 2006. This region has large interannual variability in fire activity owing to coupling between El Niño-induced droughts and anthropogenic land-use change. We show that during strong El Niño years, fires contribute up to 200 μg m−3 and 50 ppb in annual average fine particulate matter (PM2.5) and ozone surface concentrations near fire sources, respectively. This corresponds to a fire contribution of 200 additional days per year that exceed the World Health Organization 50 μg m−3 24-hr PM2.5 interim target4 and an estimated 10,800 (6,800–14,300)-person (~ 2%) annual increase in regional adult cardiovascular mortality. Our results indicate that reducing regional deforestation and degradation fires would improve public health along with widely established benefits from reducing carbon emissions, preserving biodiversity and maintaining ecosystem services.

Analysis of bones found in Romania offer evidence of human and Neanderthal

first_img(Phys.org)—DNA testing of a human mandible fossil found in Romania has revealed a genome with 4.8 to 11.3 percent Neanderthal DNA—its original owner died approximately 40,000 years ago, Palaeogenomicist Qiaomei Fu reported to audience members at a Biology of Genomes meeting in New York last week. She noted also that she and her research team found long Neanderthal sequences. The high percentage suggests, she added, that the human had a Neanderthal in its family tree going back just four to six generations. The finding by the team provides strong evidence that humans and Neanderthals continued breeding in Europe, long after their initial co-mingling in the Middle East (after humans began migrating out of Africa.) Last year, Fu and her team published a paper describing DNA analysis of a human bone fragment found in an unknown place in Siberia. Dated at 45,000 years old, the team found evidence of Neanderthal DNA, but more importantly, because it was remarkably well preserved, the relic served to strengthen a slower mutation rate than many in the field were embracing. In this new effort, Fu and her team also found that the jawbone (which still had some teeth in it) had visible Neanderthal traits, such as enlarged wisdom teeth. The jawbone was found in a cave accessible only by diving through a watery corridor back in 2002, and has been an object of study ever since. The high percentage of Neanderthal DNA is in sharp contrast to modern out-of-Africa humans, which typically have approximately one to four percent Neanderthal genes.This latest finding, along with the bone found in Siberia and others in Europe has eroded the belief that human interbreeding with Neanderthals occurred only in the Middle East. It now seems possible that humans and Neanderthals were living in the same geographic areas over the course of five thousand years, which would of course explain why their DNA appears in every person not directly descended from people in Africa, on the planet. What is still a mystery, though, is what happened to the Neanderthal? Why did they disappear even as humans continued on? Eerily, this new evidence suggests that the two were interbreeding very nearly right up to the time when the Neanderthals ceased to exist. Genetic testing shows Neanderthals less diverse than modern humans A Neanderthal skeleton, left, compared with a modern human skeleton.

Maslows pyramid of needs

first_imgThen why do we still refer to Maslow’s pioneering hierarchy of needs, named for the late Brooklyn-born psychologist Abraham Maslow, as if it’s a given truth? The visual punch of that easy-to-remember pyramid, in fact, seems to have a lot to do with its longevity, but some scholars now say that Maslow probably didn’t even create it, and many feel it fails to capture the nuances of Maslow’s more complex theories. Let’s examine all the angles. Read the whole story: Quartz Maslow’s hierarchy of needs is probably the world’s most famous framework to explain human motivation. As a refresher: It would suggest that you were driven to open this newsletter by a “higher level” need to achieve and build esteem, in this case, by picking up a bit of knowledge. This indicates that, at the moment, your “lower level” needs for food and safety are sated, as are your desires for love and belonging, leaving you free to gaze higher, toward “self-actualization.” Since the 1950s, when Maslow’s hierarchy blew up, the framework has been associated with a rainbow-hued pyramid. Textbooks carried this graphic for years, and some still do, even though most researchers who tested Maslow’s theory have found it unscientific. Though recent evidence from a large study was mixed, most studies have found the needs Maslow identified are not universal, and our requirements are not pursued in an ascending, linear fashion. One doesn’t need to live in a safe environment to seek meaning and creativity. Hunger doesn’t render love and belonging unnecessary.last_img read more

All of eight this Khan rocks

The capital was witness to the parampara tradition when sitar maestro Imrat Khan, introduced his youngest son, Azmat Ali Khan, as the next prodigy of the Khan brood at the ongoing five-day Delhi Classical Music Festival.Eight-year-old Azmat is the son of the Imrat Khan’s American wife Melinda and the youngest of his five sons – the others being Nishat, Irshad, Wajahat and Shafaatullah – all of whom are accomplished international musicians in the family Also Read – ‘Playing Jojo was emotionally exhausting’gharana.‘It is my duty to teach my sons the music we have played for generations and have given to the world. I devote all my time to teach them despite my failing health. Like all his brothers, Azmat shows promise. I cannot abandon my responsibility as a father,’ Imrat Khan said.Azmat played raga Jhinjhoti, a deviation of the Khamaja family of ragas, to a packed hall at the Kamani theatre in the capital. The playful child who drawls on his ‘r’ and ‘s’, tackled a sitar that towered way above his two-foot frame with ease, plucking the same melliflous notes as his father’s despite a few nervous misses. Also Read – Leslie doing new comedy special with NetflixAfter the recital, Azmat spoke to the media. He said he had been learning the sitar and surbahar – two instruments that his father commands at will – since the age of three.‘I practise for a couple of hours everyday under my father’s tutelage. I just love doing it. I don’t have fixed hours for taalim,’ the third-grader said.The little ‘ustaad, however, prefers the complicated surbahar and its basic sound to that of the sitar. He plays both the instruments. ‘But it is a hard choice to say which one I like better…Preferably the surbahar,’ he drawled.His fingers hurt after long hours of strumming the strings. ‘But I have to do it,’ Azmat said.‘Most of my friends in school are musicians.

NKDA takes up project to produce manure from organic waste

first_imgKolkata: New Town Kolkata Development Authority (NKDA) has taken up a pilot project to produce manure from organic waste.The solid waste composting plant was inaugurated by its chairman Debashis Sen on Thursday.The wet waste will be collected from the community market of New Town Kolkata Development Authority (NKDA).This is a situ-solid waste composting plant for conversion of organic/biodegradable waste to compost. The capacity of the plant is 1 MT/day. Continuous feeding of waste shall be done for six days and on the seventh day, the compost will be taken out. 1 MT of waste produces 100 kg of compost. Also Read – Heavy rain hits traffic, flightsOnce the waste is fed into the machine, there will not be any foul smell. Basically, the moisture from the waste is removed and after shredding it into small pieces, the process of composting is fueled by micro-organisms at some controlled temperature.If successful, the project will be replicated in other markets in New Town. This will drastically reduce the carrying cost of organic waste to the trenching ground.This is a part of the green city project by HIDCO.

Tips to stay fit healthy during pregnancy

first_imgExpecting mothers should go for pregnancy friendly exercises and should get comfortable maternity gear for working out, says an expert.Yuvraj Randhawa, gym trainer and owner of Health Plus gym (H+), gives an insight on smart ways to exercise safely during pregnancy:1. Don’t lie on your back: Avoid exercises that require you to lie flat on your back, especially crunches after the first trimester. Lying on your back for an extended period could make you feel dizzy as this can decrease blood flow to you and to your baby.  Also Read – Add new books to your shelf2. Get maternity gear: Comfort and flexibility are must during workouts but the baby bump needs to be accommodated throughout your pregnancy. Look for workout wear that is specifically sized to your times, shoe and measurements. There should be nothing too constrictive, nor anything too loose. Make sure you don’t get too warm, as over-heating can pose a threat to the baby.3. Go for pregnancy friendly exercises: Walking briskly, swimming regularly and parental yoga are all very healthy and easy on baby. Remember that your joints become loose and your centre of gravity shifts with pregnancy, so you cannot just scale down your usual routine. Seek out a moderate program that keeps you strong and fit in a relaxed and safe manner. Also Read – Over 2 hours screen time daily will make your kids impulsive4. Get more rest than usual: Most expectant mothers need more sitting, napping and relaxing, but if you have got a healthy fitness routine going, you need even more time to recoup. Don’t ever keep yourself in overdrive, no matter how much you have got going on or how great your love of working out may be. Keeping yourself fit during this time is a very healthy decision, but it also must be a wise one; listen to your body.5. Be prepared to modify your routine: You may not be able to keep up that five mile run when you’re pregnant, which is totally fine. Hormonal changes during pregnancy make you more flexible and your growing belly can throw off your centre of balance, making your standby workouts more difficult. You may lessen the time.last_img read more

State to urge Centre to reconsider introduction of new rules for DTH

first_imgKolkata: The Mamata Banerjee government will request the Centre to reconsider introduction of new rules for DTH and cable operators by the Telecom Regulatory Authority of India (TRAI) that is set come into effect from February 1.The state government is apprehensive about the step and believes that the move will not only hit the cable operators but also the consumers in the state. “The Centre has come up with this new TRAI directive that will cause inconvenience to both the consumers and the cable operators. The cable operators have been asked to hold meetings among themselves and arrive at a consensus. Accordingly, we will take up the issue with the Centre,” state Urban Development and Municipal Affairs minister Firhad Hakim said after holding a meeting with the cable operators at the Writers’ Buildings on Monday. Hakim was accompanied by Minister of State for Health Chandrima Bhattacharya.

It may be mentioned that the TRAI had said the new DTH rules will bring down the cable television bill from its existing rate. The initial deadline for migration was December 29, 2018, which was revised to January 31, 2019. With the new rules in place, the consumers will have to pay only for the channels they want to watch. “Unlike the TRAI’s predictions, the new DTH rules will compel consumers to cough up more for watching cable TV. It may happen that a consumer who currently views 150 channels would be able to view only four to five at the same amount later,” said Suresh Sethia, director of SITI Cable, which has over 40 percent market share in cable TV viewing in the city.last_img read more

Kolkata Police gets Rs 47 crore from onetime traffic fine settlement scheme

first_imgKolkata: Kolkata Police have received approximately Rs 47 crore from the one-time traffic fine settlement scheme which ended on February 13 this year. The scheme was in operation since December 1 last year.According to sources, the actual compounding amount of the pending cases was nearly Rs 300 crore. As lakhs of traffic cases were pending since 2003-04, Kolkata Police had decided to introduce a scheme to dispose of the cases and realise fine amounts as fast as possible. After a detailed discussion, it was decided to introduce the scheme in two phases. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseAccording to a senior Kolkata Police official, they had assumed that the realisation amount would cross Rs 30 crore. But no one expected that the amount would reach close to a staggering Rs 50 crore. After completion of the scheme, it was noticed that approximately 1.19 lakh cases were disposed of. The actual amount of the disposed of cases was approximately Rs 128 crore. The maximum amount was received during the first phase where the defaulters had paid only 35 percent of the actual fine amount. In the second and final phase, the defaulters had paid 50 percent of the actual fine amount.

Therefore, the present owners did not show willingness to clear the cases as the vehicle still remained in the name of previous owners. Also, several commercial vehicles completing 15 years’ tenure have been discarded. As the vehicles do not exist anymore, the owners of such vehicles were not keen to clear the pending traffic cases. Questions were raised as to how a 15-year-old vehicle could be discarded without a ‘No Objection Certificate (NOC)’ from the competent authority. Otherwise, the realisation amount could have been higher. According to sources, police will intimate the concerned courts about those who have not responded to the offered scheme. The police may appeal for necessary action against them in the concerned courts as well.last_img read more

Techsavvy people more likely to accept robot doctors

first_imgPeople with advanced computer skills are more likely to accept and use digital healthcare services and robot doctors, says a study by an Indian-origin researcher. “There is increasing use of automated systems in the medical field, where intake is now often conducted through a kiosk instead of by a receptionist,” said a Professor at Pennsylvania State University in the US. “We investigated user acceptance of these ‘robot receptionists,’ along with automated nurses and doctors,” he added. Also Read – Add new books to your shelfFor the study, scientists recruited participants from the online workforce Amazon Mechanical Turk to gain a better understanding of user psychology behind the acceptance of automation in clinics. The research team gauged the participants’ preconceived beliefs about and attitudes toward machines – what is called a “machine heuristic.” The team measured participants’ adherence to the machine heuristic by asking them to indicate their level of agreement with statements such as, “When machines, rather than humans, complete a task, the results are more accurate.” Also Read – Over 2 hours screen time daily will make your kids impulsive”We found that if you’re high on machine heuristic and you’re high on power usage, you have the most positive attitude toward automated healthcare providers. This combination seems to make people more accepting of these technologies,” said the professor. “A power user (a person with advanced computer skills) is more likely to accept a robot doctor, for example, than a non-power user.” The results were presented at the ACM Conference on Human Factors in Computing Systems in Glasgow, Scotland. According to him, the healthcare industry can benefit from increased reliance on automated systems. “Doctors are limited by their human bandwidth, by their experience, knowledge and even state of mind from minute to minute,” he said.last_img read more
