Explore further Hasegawa, a scientist affiliated with the Atominstitut der Österreichischen Universitäten and PRESTO at the Japan Science and Technology Agency, feels that the most recent experiment undertaken by him and his colleagues will offer a new way to look at questions involving quantum information processing. The results of the experiment appear in Physical Review Letters with the title “Quantum Contextuality in a Single-Neutron Optical Experiment.”Hasegawa explains that photons are most often used in quantum information technology, but that he hopes that this recent experiment, which is fundamental in nature, will contribute to the consideration of different quantum systems, including neutrons, for quantum information processing. Hasegawa and his colleagues, Rudolf Loidl and Matthias Baron from the Atominstitut and from the Institut Laue Langevin in France, and Gerald Badurek and Helmut Rauch at the Atominstitut, suggest that noncontextual theories involving neutrons are clearly violated with the results of this experiment. This most recent experiment is related to a paper published in 2003 in the journal Nature. In the previous paper, Hasegawa and his colleagues address Bell-like inequalities found in neutrons. However, with this new experiment the Kochen-Specker theorem is tackled, looking at quantum contextuality: “We use a neutron interferometer, and the Schrödinger equation represents our phenomena. We wanted to show a contradiction in noncontextual theories. We wanted to show a prediction in quantum mechanics. There’s a contradiction in Kochen-Specker with photons, and we wanted to show it with neutrons.” Hasegawa explains that the experiment took place at Institut Laue Langevin (ILL) in France, with the largest reactor in the world, and made use of polarized neutron beams split inside the interferometer. With some manipulation, observations of three separate products were measured. After the analysis was performed, the values were found to be outside the limits predicted by noncontextual hidden variable theory. The contradiction was found.There is no way to obtain a completely ideal experimental situation, Hasegawa admits, but the interferometer was key to the experiment. “Our neutron interferometer experiment is one of the best suited for such a fundamental experiment.” He also points out that single neutrons were used. “Instead of two particles as usually used in two-photon entanglement experiments,” Hasegawa says, “we used two degrees of freedom in single particles.” Even though entanglement between different particles is considered essential for their use in quantum information processing, this does not appear to be the case with single-neutrons. With the use of entanglement between degrees of freedoms in this experiment, Hasegawa believes that single particles are good candidates for quantum information processing: “This neutron case is completely different from the photon case,” he says. “They have mass and spins and obey Schrödinger equation. This experiment shows that they can probably be used for information processing as well as for fundamental research in quantum mechanics just like photons.”Hasegawa continues: “I hope that this fundamental experiment can help with further technical development in quantum information processing.”By Miranda Marquit, Copyright 2006 PhysOrg.com.All rights reserved.

Citation: Sign language puzzle solved (2009, December 15) retrieved 18 August 2019 from https://phys.org/news/2009-12-language-puzzle.html More information: Frequency of Occurrence and Information Entropy of American Sign Language, Andrew Chong, Lalitha Sankar, H. Vincent Poor (Princeton University); arXiv:0912.1768; arxiv.org/abs/0912.1768 Sign languages such as American Sign Language (ASL) use hand gestures to indicate words, and are used by millions of deaf people around the world for communication. In American Sign Language every sign is made up a combination of hand gestures and handshapes. (The sign language for British English is quite different to ASL, and the two sign languages are not mutually intelligible.)Scientists Andrew Chong and colleagues at Princeton University in New Jersey have been studying the empirical entropy and redundancy in American Sign Language handshapes to find an answer to the puzzle. The term entropy is used in the research as a measure of the average information content of a unit of data. The fundamental unit of data of ASL is the handshape, while for spoken languages the fundamental units are phonemes. A handshape is a specific movement of the hand and specific location of the hand.Their results show that the information contained in the 45 handshapes making up the American Sign Language is higher than the amount of information contained in phonemes. This means spoken English has more redundancy than the signed equivalent.The researchers reached this conclusion by measuring the frequency of handshapes in videos of signing uploaded by deaf people to websites YouTube, DeafRead, and DeafVideo.tv, and videos of conversations in sign language recorded on campus. They discovered that the entropy (information content) of the handshapes averages at 0.5 bits per shape less than the theoretical maximum, while the entropy per phoneme in speech is around three bits below the maximum possible.This means that even though making the signs for words is slower, signers can keep up with speakers because the low redundancy rate compensates for the slower rate of signing. Chong believes the signed language has less redundancy than the spoken language because less is needed. The redundancy in spoken language allows speech to be understood in a noisy environment, but Chong explains the “visual channel is less noisy than the auditory channel”, so there is less chance of being misunderstood.The researchers speculated that errors are dealt with differently in signing and speaking. If hand gestures are not understood, difficulties can be overcome by slowing the transition between them, but if speech is not understood speaking phonemes for longer times does not always solve the difficulty.Understanding sign language and its information content is essential if automated sign recognition technology is to develop, and the language needs to be understood to allow sign language to be encoded and transmitted electronically by means other than video recordings.

(Phys.org) — Intel sees a future where you simply, wirelessly, use your laptop to charge your phone. To prove its point, Intel pulled off a proof-of-concept charging feat this week at Computex where a laptop wirelessly powered a smartphone positioned alongside the computer. To demonstrate its action, Intel used an Acer Aspire laptop with a Samsung smartphone. The computer was shown as having a plug-in transmitter module on its right side, for the charging. The compatible phone, with its receiver placed alongside the laptop transmitter, started charging. A ping sound and notification confirm the connection has been made and the process is in effect.

Power instantly begins to flow from the laptop to the phone. How long would the exercise take to get a phone working? The demo rep was heard in the video saying “Bring it into your meeting, and by the end of the meeting, you have enough to go for the rest of the day.”Intel claims to be able to deliver up to three watts of power via the system, which is considered as more than enough to charge most mobile devices.While a knee-jerk reaction may be one of high hopes that this will be commercialized soon so that you need not lug around a phone charger when mobile, some tech watchers say to think twice. They are raising interesting questions about how useful this proof of concept may be. In fact, they suggest that possible power downsides could render the inconvenience of carrying around a phone charger trivial. Questions are raised about how much battery life might be sapped from the laptop to power the phone. As Technology Review comments, one may be put in a zero sum game if the phone is drawing down battery power from the laptop. Intel at Computex had earlier drawn visitors toward another charging demo, this time showing an easy charging option for a wireless keyboard. All one would need to do is place the keyboard on the base of the computer and it would begin charging. The user touches the base of the PC to activate the ability of the keyboard. There was no word on production versions. An Intel spokesperson said that the company has considered porting the technology over to other accessories.

© 2014 Phys.org The technique dates back to lab work in the 1940s. In more recent times. Spanish chef Ferràn Adria brought the technique to highly creative modern cuisine at his restaurant elBulli. The Ooho ingredients are water, calcium chloride and brown algae. The Ooho team applied the concept not to elegant caviar or pea soup renderings but to water. Their project involved their experimenting with different portions and dimension of their brown algae, calcium chloride and water ingredients and they developed a suitable double gelatinous membrane. An estimated cost to make this water ball is not exactly prohibitive—two cents a unit. The double membrane protects the inside hygienically, one of the designers said in Fast Company.A report on the team’s efforts in designboom, the digital architecture and design magazine, said the inspiration for their entry came from nature’s way of encapsulating liquid using membranes, as in the egg yolk. The Ooho team succeeded in creating their edible membrane as an alternative to the plastic water bottle. To achieve their double gelatinous membrane they used sodium alginate from the brown algae and calcium chloride in proportions that could generate gelification. While companies have the infrastructure to manufacture packaging, according to the report in designboom, the main idea of Ooho “is that everyone could make them at their kitchen, modifying and innovating the ‘recipe.’ From DIY to CIY (Cook It Yourself).” (Phys.org) —Think about it. A Sunday in the park. Trashbins overflow with plastic water bottles cast off by joggers, power walkers and their cheering supporters. They have gone home after a charitable athletic event to raise money for—you guessed it—the environment. Are we going nowhere very fast? A water container called the Ooho is a potential option; it is biodegradable and edible. The Ooho was created by three designers and has been named one of 12 winners of the Lexus Design Award 2014. This is an international design competition, where 1,157 submissions were received during the application period and from that group, 12 winners were selected after consideration by six judges. One may describe this entry as a water ball or more specifically as membrane packaging for liquids. Rodrigo García Gonzalez, Pierre Pasalier, and Guillaume Couche are the designers. After all, are plastic bottles the choice containers for water? The designers came up with a holder for water in the form of a double membrane. The process they used is known as “spherification,” a technique used in culinary circles for shaping liquids into sphheres resulting in artistic presentations of food that look like magical jewels.

Under visible light illumination, the nanoscale photocatalysts perform the water-splitting reduction half-reaction with 100% efficiency. Credit: Lilac Amirav, Technion-Israel Institue of Technology The researchers, Philip Kalisman, Yifat Nakibli, and Lilac Amirav at the Technion-Israel Institute of Technology in Haifa, Israel, have published a paper on the perfect efficiency for the water reduction half-reaction in a recent issue of Nano Letters.”I strongly believe that the search for clean and renewable energy sources is crucial,” Amirav told Phys.org. “With the looming energy crisis on one hand, and environmental aspects, mainly global warming, on the other, I think this is our duty to try and amend the problem for the next generation. “Our work shows that it is possible to obtain a perfect 100% photon-to-hydrogen production efficiency, under visible light illumination, for the photocatalytic water splitting reduction half-reaction. These results shatter the previous benchmarks for all systems, and leave little to no room for improvement for this particular half-reaction. With a stable system and a turnover frequency of 360,000 moles of hydrogen per hour per mole of catalyst, the potential here is real.”When an H2O molecule splits apart, the three atoms don’t simply separate from each other. The full reaction requires two H2O molecules to begin with, and then proceeds by two separate half-reactions. In the oxidation half-reaction, four individual hydrogen atoms are produced along with an O2 molecule (which is discarded). In the reduction half-reaction, the four hydrogen atoms are paired up into two H2 molecules by adding electrons, which produces the useful form of hydrogen: H2 gas. (Left) Transmission electron microscope images of the nanorod photocatalysts with (a) one and (b) two platinum tips. (Right) A comparison of the efficiencies shows the advantage of using a single platinum tip. Credit: Kalisman, et al. ©2016 American Chemical Society Journal information: Nano Letters (Phys.org)—Splitting water is a two-step process, and in a new study, researchers have performed one of these steps (reduction) with 100% efficiency. The results shatter the previous record of 60% for hydrogen production with visible light, and emphasize that future research should focus on the other step (oxidation) in order to realize practical overall water splitting. The main application of splitting water into its components of oxygen and hydrogen is that the hydrogen can then be used to deliver energy to fuel cells for powering vehicles and electronic devices. Explore further In the new study, the researchers showed that the reduction half-reaction can be achieved with perfect efficiency on specially designed 50-nm-long nanorods placed in a water-based solution under visible light illumination. The light supplies the energy required to drive the reaction forward, with the nanorods acting as photocatalysts by absorbing the photons and in turn releasing electrons needed for the reaction. Citation: Scientists achieve perfect efficiency for water-splitting half-reaction (2016, February 26) retrieved 18 August 2019 from https://phys.org/news/2016-02-scientists-efficiency-water-splitting-half-reaction.html Clean energy from water © 2016 Phys.org The 100% efficiency refers to the photon-to-hydrogen conversion efficiency, and it means that virtually all of the photons that reach the photocatalyst generate an electron, and every two electrons produce one H2 molecule. At 100% yield, the half-reaction produces about 100 H2 molecules per second (or one every 10 milliseconds) on each nanorod, and a typical sample contains about 600 trillion nanorods.One of the keys to achieving the perfect efficiency was identifying the bottleneck of the process, which was the need to quickly separate the electrons and holes (the vacant places in the semiconductor left after the electrons leave), and remove the holes from the photocatalyst. To improve the charge separation, the researchers redesigned the nanorods to have just one platinum catalyst instead of two. The researchers found that the efficiency increased from 58.5% with two platinum catalysts to 100% with only one.Going forward, the researchers plan to further improve the system. The current demonstration requires a very high pH, but such strong basic conditions are not always ideal in practice. Another concern is that the cadmium sulfide (CdS) used in the nanorod becomes corroded under prolonged light exposure in pure water. The researchers are already addressing these challenges with the goal to realize practical solar-to-fuel technology in the future.”We hope to implement our design rules, experience and accumulated insights for the construction of a system capable of overall water splitting and genuine solar-to-fuel energy conversion,” Amirav said. “The photocatalytic hydrogen generation presented here is not yet genuine solar-to-fuel energy conversion, as hole scavengers are still required. CdS is unfortunately not suitable for overall water splitting since prolonged irradiation of its suspensions leads to photocorrosion. We have recently demonstrated some breakthrough on this direction as well. The addition of a second co-catalyst, such as IrO2 or Ru, which can scavenge the holes from the semiconductor and mediate their transfer to water, affords CdS-based structures the desired photochemical stability. I believe this is an important milestone.” More information: Philip Kalisman, et al. “Perfect Photon-to-Hydrogen Conversion Efficiency.” Nano Letters.

Citation: High-speed video study reveals the nature of the cobra wave (2017, August 29) retrieved 18 August 2019 from https://phys.org/news/2017-08-high-speed-video-reveals-nature-cobra.html A small team of researchers from multiple institutions in France has learned more about the properties of the “cobra wave” by building structures from popsicle sticks and filming wave progressions with a high-speed camera. In their paper published in the journal Physical Review Letters, Jean-Philippe Boucher, Christophe Clanet, David Quéré and Frédéric Chevy describe the series of experiments they carried out with the sticks and what they learned in the process. A cobra wave is, by definition, a wave that occurs when popsicle sticks are bound together in a certain way under tension and are then released—the sticks become unbound as the wave propagates the length of the structure. Understanding the cobra wave and how it works is important because researchers believe that some biological processes work in the same way.To learn more about the cobra wave, the group assembled a large number of popsicle lattices in arrangements that were similar to previous methods of creating the effect—each resembled a number of Xs lined up next to one another, sort of like the small fences used in a flower garden. The two ends had a different configuration, with sticks placed in such a way as to prevent adjacent ones from unraveling. Once the structure is set, all it takes is pulling one stick from the end to create the wave, which moves in fashion similar to dominoes—one stick unraveling causes the next to unravel, until the structure is undone. There is one particularly unique characteristic of the wave—as it gets going, the part of the structure that has not come undone rises into the air, causing the structure to bend in the shape of a cobra about to strike. Another characteristic of the structure and associated wave is the sticks flying every which way as the wave progresses, creating an impressive display. Via highs-speed video of multiple waves in action with the variably sized popsicles sticks arranged in slightly different ways, the researchers learned that stick length must fit into a narrow range of possibilities. They also found that the recoil was due to sticks being ejected. The sticks, of course, got their kinetic energy from the stored potential energy derived from bending. The team also derived wave speed formulas based on characteristics of the sticks. As for the unique cobra shape, the team found that it resulted from competition between the recoil from sticks being ejected and gravitational forces. More information: Jean-Philippe Boucher et al.

The Bureau of Indian Standards has taken positive steps towards giving impetus to Modi government’s ambitious “Make In India” campaign by proposing changes in the BIS Act,1986. The need for amendment to BIS Act,1986 accrued from situations demanding BIS to keep pace with the changing requirements of the industry.The BIS Act has never been amended since its enactment in 1986. Due to certain limitations, difficulties being faced in implementation and ambiguity of the provisions, amendment to the BIS Act, 1986, have become necessary. The stakeholders’ meet on the subject was held at BIS which was presided over by Minister of Consumer Affairs, Food and Public Distribution Ram Vilas Paswan. The stakeholders included major industry associations including FICCI, ASSOCHAM, PHDCCI, CII, representatives from Ministry of Power, Ministry of Steel, Ministry of Commerce, Ministry of Health and Welfare and all consumer associations.

The rainy season may affect the immune system, so it is important to keep yourself hydrated and eat lots of green vegetables, says an expert.Here are a few tips:* Go green: Asparagus, cucumber, broccoli, leafy vegetables, zucchini and green vegetables are ideal. They have enough liquid content to keep the body hydrated and enough protein to provide energy. They keep you relaxed without causing any digestive irritations. * Avoid cold water: What that ice cold water does is effectively douse the digestive fires. This will cause digestive problems and a feeling of lack of energy. Water at room temperature assimilates into your body faster and rehydrates you quickly. Also Read – ‘Playing Jojo was emotionally exhausting’* Cold-pressed juices: You might have heard about the term ‘cold-pressed juices’ being thrown around these days in discussions on health and fitness. It is actually an alternate process of juicing fruits wherein they are mashed at first and then external pressure is applied to extract the juice. In this way, the enzymes inside the fruit remain intact. They are also great in alkalising the acid build up in the body to keep the pH level neutral.

Undeniably, however, is the refreshing, delicious taste of this fruit that makes it a perfect drink. * Pomegranate: It helps to enhance the blood flow and detoxify the body of impurities. Another great source of Vitamin C. It is extremely hydrating and its juice delivers essential micro-nutrients and photo chemical to the skin.
A common food additive found in chewing gums, chocolates and breads may significantly reduce the ability of small intestine cells to absorb nutrients and block pathogens, a new study has warned.”Titanium oxide is a common food additive and people have been eating a lot of it for a long time, but we were interested in some of the subtle effects, and we think people should know about them,” said Gretchen Mahler, a professor at the Binghamton University in the US. Also Read – Add new books to your shelf”There has been previous work on how titanium oxide nanoparticles affects microvilli, but we are looking at much lower concentrations,” Mahler said.”We also extended previous work to show that these nanoparticles alter intestinal function,” she said.Titanium dioxide is generally recognised as safe by the US Food and Drug administration and ingestion is nearly unavoidable. The compound is an inert and insoluble material that is commonly used for white pigmentation in paints, paper and plastics. It is also an active ingredient in mineral-based sunscreens for pigmentation to block ultraviolet light. However, it can enter the digestive system through toothpastes, as titanium dioxide is used to create abrasion needed for cleaning.

A previous study had tested 89 common food products including gum, Twinkies, and mayonnaise and found that they all contained titanium dioxide.About five per cent of products in that study contained titanium dioxide as nanoparticles.”To avoid foods rich in titanium oxide nanoparticles you should avoid processed foods, and especially candy. That is where you see a lot of nanoparticles,” Mahler said. Researchers exposed a small intestinal cell culture model to the physiological equivalent of a meal’s worth of titanium oxide nanoparticles – 30 nanometres across – over four hours (acute exposure), or three meal’s worth over five days (chronic exposure). Acute exposures did not have much effect, but chronic exposure diminished the absorptive projections on the surface of intestinal cells called microvilli.With fewer microvilli, the intestinal barrier was weakened, metabolism slowed and some nutrients – iron, zinc, and fatty acids, specifically – were more difficult to absorb.Enzyme functions were negatively affected, while inflammation signals increased.The study was published in the journal NanoImpact.
