The company has focused on refining the technology of their electric bikes for best performance.The company–the result of founder Richard Hatfield getting together with engineers who shared his belief that clean tech transportation can deliver high performance–continues to work out technical challenges. Its key goal is placing electronic motorcycle technology in parity with gas-powered motorcycles.Lightning Motorcycles is especially happy with its choice of the Ener1 lithium-ion battery pack used in the record-breaking run. The driver of the SuperBike was Paul Thede, the owner of Race Tech. Thede, who has a degree in mechanical engineering from California Polytechnic University, is known as a motorcycle suspension guru. He developed the Lightning SuperBike’s suspension system. For Thede, breaking the 200 mph mark on an electric motorcycle was special not just for the numbers, he said, but because it is a step toward “green” technology.

first_imgCredit: Linnaeus University (Phys.org) —A trio of researchers at Stanford University has shined a light on a problem many in the social science research arena are aware of but tend to ignore: the problem of null result papers not being written or published. In their paper published in the journal Science, Annie Franco, Neil Malhotra and Gabor Simonovits suggest that not publishing null result papers produces a bias in the literature, skewing the reliability of papers with strong results that are published. Jeffery Mervis offers an In Depth piece on the team’s work in the same journal edition.

We leverage TESS, an NSF-sponsored program where researchers propose survey-based experiments to be run on representative samples of American adults. Because TESS proposals undergo rigorous peer review, the studies in the sample all exceed a substantial quality threshold. Strong results are 40 percentage points more likely to be published than null results, and 60 percentage points more likely to be written up. We provide not only direct evidence of publication bias, but also identify the stage of research production at which publication bias occurs—authors do not write up and submit null findings.center_img This document is subject to copyright.

What should a social scientist do if he or she comes up with a hypotheses regarding human behavior, designs a way to test it, runs that test, but then learns that nothing new has been found by doing so? At first blush, it might seem logical to toss the idea into the trash, or file drawer and move on to something else, which is exactly what a lot of researchers do, the researchers with this new effort report. After all, if you don’t find anything relevant or pertinent, others might think you didn’t actually accomplish anything, so why would you write up a paper describing what happened and submit it to a journal?The answer lies in the domain of published results, if respected journals only ever publish strong result papers, an impression is created that only research that provides strong results is important, which of course is nonsense. It also leaves the science open to wasted effort when other researchers come up with the same hypotheses and the same result.To learn more about the problem, the researchers pulled data from TESS, an online program that allows researchers to get data from surveys that have been conducted as part of research efforts sponsored by the National Science Foundation. The team found that only 48 percent of studies begun were completed, so they contacted the study leaders to find out what happened to those that weren’t represented. Their work revealed that just 20 percent of null result papers wound up being published, and that an astounding 65 percent of the null result studies had even resulted in a written paper—the researchers had simply walked away. When asked why, many suggested that to do so would be wasted effort as there would be little interest by journals.The researchers suggest that perhaps a new repository be set up for the placement of null result papers, one that would be accessible by other researchers. That would allow for a future scenario when a scientist could ask their computer about an idea, and get back a history of the research surrounding it, rather than a skewed list that shows only the work of successful endeavors. © 2014 Phys.org Journal information: Sciencelast_img read more

first_img Citation: Quantum computer that ‘computes without running’ sets efficiency record (2015, August 31) retrieved 18 August 2019 from https://phys.org/news/2015-08-quantum-efficiency.html © 2015 Phys.org Journal information: Physical Review Letters The researchers explain that the “on” and “off” states can be thought of as the two paths of an interferometer, where a photon may take one path or the other, but not both.”Such a situation is very similar to the case of a photon passing through a two-way interferometer,” Jiang said. “When a detector on one of the paths catches the photon, then one says the photon does not go on the other path. Similarly, when the whole system collapses into the ‘off’ subspace, one can conclude that the computer does not run. After each repetition, the state changes slightly. It finally evolves to a certain value after N repetitions from its initial value. By detecting its state, we get the information that is ‘programmed’ in the computer, although the computer has not run.” Breaking the efficiency limitPrevious experimental CFC protocols have faced a counterfactual efficiency limit of 50%, where the counterfactual efficiency is defined as “the average probability of learning the result of a computation without running the computer.” But the generalized CFC (first proposed by G. Mitchison and R. Jozsa in 2001) does not face this limit, which allowed the researchers in the new study to experimentally demonstrate an efficiency of 85% at 17 pulse repetitions. “The key difference between the two protocols is that the ‘off’ subspace of the generalized CFC is dependent on the choice of the ‘algorithm’ (Ur), whereas it is independent in the controlled-Ur CFC,” said coauthor Chenyong Ju at the University of Science and Technology of China. “As a consequence of this fact, the sum of the ‘volume’ of each ‘off’ subspace, which has a direct relation to the counterfactual efficiency, is much larger for the generalized CFC than the controlled-Ur CFC.”The higher efficiency opens up the possibility of developing highly efficient yet very low-light imaging technology. This technology could be useful in any situation in which light may damage or destroy the illuminated sample, which makes the method particularly relevant for biological imaging. Applications may include imaging green fluorescent proteins that might be bleached under laser light, as well as UV imaging of cells and safe X-ray imaging. In some situations, these applications might be performed using only a single photon.”The use of one photon is just for the special case that the object to be imaged has only one pixel being transparent, whereas the other pixels are opaque,” said coauthor Fei Kong at the University of Science and Technology of China. “To image the object with our protocol, one may imagine that the situation in which a photon is absorbed by an opaque pixel is just like the computer evolving into the ‘on’ subspace. Such a process is effectively avoided in our protocol. The photon will eventually ‘find’ the transparent pixel and pass through it. Through a detector below, one can locate this pixel and hence accomplish the imaging with just one photon. The number of photons needed is proportional to the number of transparent pixels, whereas normal imaging methods need [many more] photons.”In the future, the researchers also plan to investigate potential applications of counterfactual computing for secure communication.”We are looking forward to exploring more realistic applications of the generalized CFC,” Du said. “There are several recent works on the topic of counterfactual quantum cryptography and communication. Employing the counterfactual quantum phenomenon, several groups have proposed and demonstrated a new model of secret communication in which no physical signal particles are transmitted, which provides practical security advantages. [For example, see here, here, and here.] We wonder what the potential of the generalized CFC is in this area.” Paving the way for a faster quantum computer Now in a new paper, scientists have experimentally demonstrated a slightly different version called a “generalized CFC” that has an efficiency of 85% with the potential to reach 100%. This improvement opens the doors to realizing a much greater variety of applications, such as low-light medical X-rays and the imaging of delicate biological cells and proteins—in certain cases, using only a single photon. The researchers, led by Prof. Jiangfeng Du at the University of Science and Technology of China and Prof. Liang Jiang at Yale University in the US, have published a paper on the high-efficiency counterfactual computing method in a recent issue of Physical Review Letters.”The main keys to achieving high-efficiency CFC include the utilization of exotic quantum features (quantum superposition, quantum measurement, and the quantum Zeno effect), as well as the use of a generalized CFC protocol,” Du told Phys.org. How counterfactual computing worksBy “not running,” the scientists mean that the computer—which can operate in either an “on” subspace or an “off” subspace—stays in its “off” subspace for the entire computation. Physically maintaining the computer in the “off” subspace, in this scheme, involves controlling the spin properties of a diamond system, which acts as a quantum switch. Some of the spins must be kept in a superposition state, in which they occupy two states at the same time. To control the spin superposition, the physicists took advantage of the quantum Zeno effect, in which frequent measurements on a system can “freeze” the system in its current state. By applying a sequence of pulses to the system, the scientists could keep the system in its “off” subspace, and so keep it from running. “The procedure comprises a quantum switch and a quantum register,” Jiang explained. “For each repetition, we prepare the quantum switch into a quantum superposition state, including two coherent parts (‘on’ and ‘off’). Then the ‘algorithm,’ a NOT gate on the quantum register in our case, is performed in the ‘on’ subspace. Although it seems the computer has run in this step, a consequent projective measurement will remove all the changes in the ‘on’ subspace, since the probability of the whole system collapsing into the ‘off’ subspace during the measurement is very large (approaches 100% as the number of repetitions tends to infinity utilizing the quantum Zeno effect).” More information: Fei Kong, et al. “Experimental Realization of High-Efficiency Counterfactual Computation.” Physical Review Letters.

Credit: Kong, et al. ©2015 American Physical Society Explore further (Phys.org)—Due to quantum effects, it’s possible to build a quantum computer that computes without running—or as the scientists explain, “the result of a computation may be learned without actually running the computer.” So far, however, the efficiency of this process, which is called counterfactual computation (CFC), has had an upper limit of 50%, limiting its practical applications.

first_imgÖzgür Aytürk Culture and Tourism Counsellor of the Turkish Embassy in India takes pride in promoting his country’s culture and tourism and has taken several steps to tap into the ever-increasing outbound travellers market from India. In an interview with Millennium Post he speaks about how both Turkey and India are connected culturally.Can you tell us about the cultural of your country and how similar it is to India?Turkey is on the crossroads of Europe, Asia and the Middle East and that in itself makes it unique. And it is for this reason that for centuries Turkey has seen many civilisations come and go and has had the fortune of evolving a diverse and rich heritage and culture much like India. So when one visits Turkey today you will find richness of this diversity in every part of the country and especially in Istanbul as it was capital to three different empires in the history. So one would find a great mix of religious worship places, cuisine, and cultural all under one roof in Istanbul. Also Read – ‘Playing Jojo was emotionally exhausting’What steps have you taken to improve cultural relations between India and Turkey?We think that culturally we are close to India unfortunately, however, we have to remind this to the people of both the nations. Both India and Turkey share common platforms in terms of cuisine, general characteristics amongst our people, hospitality and even language.  In fact there are more than 9,000 words that are same or similar in both the languages. To remind both the nations of these similarities we have been organising several cultural nights or supporting them. Also Read – Leslie doing new comedy special with NetflixSufism is another string that binds both the countries musically and culturally hence we have orgainsed several Sufi festivals. The last one was performed at the Rastrapati Bhawan. So we are trying to promote and showcase these similarities in order to build stronger cultural ties. We had also organised a Turkish food festival some time back which got a good response. We are also looking at establishing a cultural centre in Delhi, once that is established we will be holding Turkish events more often in the city and we hope to have it established by the end of this year. What is the role of the Indian travel fraternity in promoting Turkey among Indian travellers?Now people are using websites more often but still when you look at this market, majority of them are still going to the travel agents before making their decisions. They still have a great impact on the end consumers while shaping their decisions and making their vacation plans. That is why we will be supporting the travel trade through road shows, fun trips, media campaigns that are going on. What segments are you looking to promote in India? Please tell us about your strategies in targeting these.MICE definitely. Although, we do not have certain breakup for MICE and leisure, we believe that more than 20 percent visit Turkey for MICE purpose and little less for leisure. We are focusing on MICE because we think Turkey has many things to offer. It has very beautiful and big convention facilities. Ontalia is hosting the ICCA 2014 conference, Ismeirs and some other cities have big convention venues.On the other side, wedding is becoming very popular for Turkish private sectors. We are getting queries from Turkish hoteliers and associations. We are willing do so something on wedding and golf. We are inviting decision makers and tour operators to showcase the gold destinations. We have been organising Istanbul shopping fest for the past two years. Istanbul shopping fest is 20 days shopping fest, where we have lucky draws every day and people can win every day.Has Turkey seen many repeat travellers from India?Turkey is  a destination which can’t be explored at one go. If you are curious about the country you have to definitely return. They visit Istanbul and when they return they tell their friends and start planning for other trips. I can’t say about promoting Turkey as a repeat destination because the numbers from India are still below our expectations.last_img read more

Also Read – ‘Playing Jojo was emotionally exhausting’The event was part of the finale event marking a show curated by the Delhi-based artist collective Khoj. Titled Nameless Here for Evermore it showcased art reflecting on global suffering and collective trauma. “It was fairly disturbing”, says Amitesh Grover, an assistant professor at the National School of Drama who was invited by Khoj to put up the performance.“I wanted to investigate what mourning means. I have been observing a lack of collective mourning in urban society. It is entirely absent in society. Nowadays we do not meet to mourn collectively,” says Grover. Also Read – Leslie doing new comedy special with NetflixDuring his research Grover spent some time in Tirunelveli and among Oppori singers, of whom he says there is no correct estimate available. “There are no correct estimates on the community. It is a dying tradition. No new women were interested or allowed to practice and existing Oppori singers are stigmatised by neighbours and not invited to weddings etc because they are thought to carry the stigma of death,” says Grover. Lakshmi, who ran away from her abusive husband provided an intimate autobiographical account of her life and sorrows to a select audience in Delhi, which was visibly moved by the performance. Some people even completely broke down into tears moved by the sheer force of her songs. “The event was designed for her to see death not just as a private affair but also a lament,” says Grover.“Lakshmi has been singing for 20 years now and we set up a tutorial during event so that the young artist Janagi learnt to sing the Oppori repeating after Lakshmi,” says Grover.The show was intended as a way to look at transferrance of the quality of mourning, to set up a dialogue with a traditional performative practice. “It is a deep experience,” says Grover.“From my perspective I wanted to see how Lakshmi managed to produce tears. Everytime, I have seen her perfrom I have seen her cry and the tears are genuine. Sometimes she had to stop and wipe them away. She brings out the intimate sadness and to me that is mark of a true performer,” says Grover. The performer herself draws strength from the responses of the audience. She sings, wails and beats her chest and accompanied to the sounds of a beating drum she helps mourners bring their burried grief to the surface.Meanwhile, the Khoj show has got togther an exhibition of multimedia artworks by 10 international artists based on various incidents like the violence in Jammu and Kasmir over the last decade, the Punjab and Delhi riots of 1984, the occupation of Afghanistan besides others.last_img read more

There is a plan to impart training on beekeeping among unemployed rural youth, particularly in Bongaon and Basirhat sub-divisions. The youth would be trained by forming small groups. According to the plans, the district horticulture officials would conduct awareness campaign among rural youth, to encourage them for bee-farming. It would also convince the people to take up bee-keeping as an occupation to increase agriculture products.Bee cultivators would soon get their identity cards. The scheme would not benefit the poor beekeepers but it would increase the overall production of honey.The state Horticulture department would ensure that beekeepers get a good price for their produce in various state government markets.last_img read more
