Penn Theorists to Create Optical Circuit Elements (PhysOrg.com) — “If you open up almost any electronic gadget, you will see various elements that operating using electric circuitries,” Nader Engheta tells PhysOrg.com. “Many of them have different functionalities, such as inductors, capacitors, resistors, transistors, and so forth. These well-known elements have been around for decades. But what if you could bring these concepts to the nanoscale, and what if they could operate with light instead of electricity?” This document is subject to copyright.

Engheta and Alů describe their concept of an optical nanoscale circuit in Physical Review Letters: “All-Optical Metamaterial Circuit Board at the Nanoscale.””If you go to the nanoscale,” Engheta explains, “you would have to conceive of nanoparticles that effectively act like the elements seen in current devices. It would be necessary to create nanoparticles of a specific shape, and made from specific materials, that would allow them to act as capacitors, resistors, and other well-known elements.”There are three main advantages of using optical nanoparticle circuit boards, Engheta says. First of all, being able to further miniaturize various communications devices would ensure that technology continues to evolve. “We are moving toward having more and more information compacted into a smaller volume.” The second advantage is that using optical frequencies would provide more bandwidth. Finally, there is a very real possibility that nanoscale circuit boards, properly constructed, would use less energy. “We have to look more into this possibility, but it is quite likely that optical nanoparticle circuit boards would be low energy in nature,” Engheta insists.So far, Engheta and Alů have only used computer simulations to test their ideas related to nanoscale circuit boards. The Engheta group is, however, working toward an experimental realization of their theories with a proof of concept for lumped circuit elements. “What we’ve come up with is compatible with the nanofabrication techniques already in use today,” Engheta says. “We are in the midst of trying to construct some nanowires to serve as our proof of concept for lumped optical circuit elements, and hopefully we’ll see some results in the next six months or so.”One of the biggest challenges to realizing this type of nanoscale circuitry is that it is difficult to form the structures needed at such a small size. “Additionally,” Engheta admits, “we would have to put these structures next to each other in specific patterns. This is doable, using present nanofabrication techniques, but not easy.” The fabrication process would include creating structures out of metamaterials and a process that imitates the electronic circuitry we are more familiar with. “One of our ideas is to cut a groove in the material, one that could contain the light used in the circuit board, to connect nanoparticles together. It would be similar to the way wires connect various elements in electronic devices.”Once a proof of concept is realized for this circuit board, Engheta hopes to take optical nanocommunications to another level. “We are extending our concept to other elements that are non-linear,” he says. “This could allow us to develop switches, opening the door to computation.”More information: Andrea Alů and Nader Engheta, “All Optical Metamaterial Circuit Board at the Nanoscale,” Physical Review Letters (2009).

first_img D-Wave researchers demonstrate progress in quantum computing (Phys.org) — While there has been some skepticism as to whether the Canadian company D-Wave’s quantum computing system, the D-Wave One, truly involves quantum computing, the company is intent on proving that the system is both a quantum device as well as a useful one. In a new study, D-Wave CEO Geordie Rose and other D-Wave researchers have teamed up with Harvard quantum physicist Alán Aspuru-Guzik and post-doc Alejandro Perdomo-Ortiz to demonstrate that the D-Wave One system can solve the challenging task of finding the lowest-energy configuration of a folded protein. D-Wave One and CEO Geordie Rose. Image credit: D-Wave Systems, Inc. The study, “Finding low-energy conformations of lattice protein models by quantum annealing,” is published in a recent issue of Nature’s Scientific Reports. The computer used quantum annealing to find the lowest-energy protein configuration by solving for the configuration as an optimization problem, where the optimal state was the lowest-energy state. Proteins can be folded in a large number of ways because they’re made up of many chains of amino acids. Yet somehow, proteins almost always manage to fold themselves in the correct configuration (when they don’t fold correctly, they can cause misfolded-protein diseases such as Alzheimer’s, Huntington’s, and Parkinson’s). Scientists think that proteins fold themselves correctly because the correct configuration is also the state of lowest energy, the state at which the protein becomes stable.In quantum annealing, the system starts by randomly picking a starting state, and then selecting random neighbor states to see if they have lower energies than the starting state. If they do, the computer replaces the original state with the lower-energy state. The process is considered quantum because it involves quantum tunneling to explore the different states by traveling directly through certain barriers rather than climbing over them. In this way, quantum annealing differs from the classical version, called “simulated annealing,” which explores different states based on temperature. Previous research has shown that quantum annealing has advantages over simulated annealing in some situations.In this study, the researchers showed that D-Wave One – which has the distinction of being the first commercial quantum annealer – can solve some simple protein folding problems by annealing all the way to the ground state. The problems here only contain a small number of amino acids, so they have only a relatively small number of possible configurations, and can still be solved on a classical computer. Also, the quantum technique has low odds of measuring the ground state, with only 13 out of 10,000 measurements yielding the desired solution. The researchers attribute this low percentage in part to the limitations of the machine itself, and in part to thermal noise that disrupted the computation. Nevertheless, the study provides the first quantum-mechanical implementation of protein models using a programmable quantum device.“Harnessing quantum-mechanical effects to speed up the solving of classical optimization problems is at the heart of quantum annealing algorithms (QA),” the researchers wrote in their study. “There is theoretical and experimental evidence of the advantage of solving classical optimization problems using QA, over its classical analogue (simulated annealing). In QA, quantum mechanical tunneling allows for more efficient exploration of difficult potential energy landscapes such as that of classical spin-glass problems. In our implementation of lattice folding, quantum fluctuations (tunneling) occurs between states representing different model protein conformations or folds.”The study also lends more support to the quantum nature of the D-Wave One, since the system behaved exactly as expected if quantum aspects were contributing. The researchers see even more to look forward to in the future.“The approach employed here can be extended to treat other problems in biophysics and statistical mechanics, such as molecular recognition, protein design, and sequence alignment,” they wrote.

DOI:10.1038/srep00571AbstractLattice protein folding models are a cornerstone of computational biophysics. Although these models are a coarse grained representation, they provide useful insight into the energy landscape of natural proteins. Finding low-energy threedimensional structures is an intractable problem even in the simplest model, the Hydrophobic-Polar (HP) model. Description of protein-like properties are more accurately described by generalized models, such as the one proposed by Miyazawa and Jernigan (MJ), which explicitly take into account the unique interactions among all 20 amino acids. There is theoretical and experimental evidence of the advantage of solving classical optimization problems using quantum annealing over its classical analogue (simulated annealing). In this report, we present a benchmark implementation of quantum annealing for lattice protein folding problems (six different experiments up to 81 superconducting quantum bits). This first implementation of a biophysical problem paves the way towards studying optimization problems in biophysics and statistical mechanics using quantum devices.

first_imgFuller et al. propose a model for the synthesis of heavy elements in which a rapidly rotating neutron star is swallowed from the inside by a tiny black hole. The centrifugally deformed star, shown in cross-section, sheds considerable mass at its equator as it spins up and angular momentum is transferred outward. Heavy atomic nuclei, including gold and platinum, can form via the r-process in the neutron-rich matter that’s expelled from the imploding star. Credit: APS/Alan Stonebraker, via Physics Citation: New theory suggests heavy elements created when primordial black holes eat neutron stars from within (2017, August 24) retrieved 18 August 2019 from https://phys.org/news/2017-08-theory-heavy-elements-primordial-black.html Space scientists are confident that they have found explanations for the origins of light and medium elements, but are still puzzling over how the heavier elements came to exist. Current theories suggest they most likely emerged during what researchers call an r-process—as in rapid. As part of the process, large numbers of neutrons would come under high densities, resulting in capture by atomic nuclei—clearly, an extreme environment. The most likely candidate for creating such an environment is a supernova, but there seem to be too few of them to account for the amounts of heavy elements that exist. In this new effort, the researchers offer a new idea. They believe it is possible that PBHs occasionally collide with neutron stars, and when that happens, the PBH becomes stuck in the center of the star. Once there, it begins pulling in material from the star’s center.PBHs are still just theory, of course. They are believed to have developed shortly after the Big Bang. They are also believed to roam through the galaxies and might be tied to dark matter. In this new theory, if a PBH happened to bump into a neutron star, it would take up residence in its center and commence pulling in neutrons and other material. That would cause the star to spin rapidly, which in turn would fling material from its outermost layer into space. The hurled material, the researchers suggest, would be subjected to an environment that would meet the requirements for an r-process, leading to the creation of heavy metals.The theory assumes a certain number of such collisions could and did occur, and also that at least some small amount of dark matter is made up of black holes, as well. But it also offers a means for gathering real-world evidence that it is correct—by analyzing mysterious bursts of radio waves that could be neutron stars imploding after internal consumption by a PBH. Explore further Primordial black holes may have helped to forge heavy elements Journal information: Physical Review Letterscenter_img (Phys.org)—A team of researchers at the University of California has come up with a new theory to explain how heavy elements such as metals came to exist. The group explains their theory in a paper published in the journal Physical Review Letters—it involves the idea of primordial black holes (PBHs) infesting the centers of neutron stars and eating them from the inside out.

DOI: 10.1103/PhysRevLett.119.061101ABSTRACTWe show that some or all of the inventory of r-process nucleosynthesis can be produced in interactions of primordial black holes (PBHs) with neutron stars (NSs) if PBHs with masses 10−14 M⊙ < M PBH < 10−8 M⊙ make up a few percent or more of dark matter. A PBH captured by a NS sinks to the center of the NS and consumes it from the inside. When this occurs in a rotating millisecond-period NS, the resulting spin-up ejects ∼0.1 M⊙–0.5 M⊙ of relatively cold neutron-rich material. This ejection process and the accompanying decompression and decay of nuclear matter can produce electromagnetic transients, such as a kilonova-type afterglow and fast radio bursts. These transients are not accompanied by significant gravitational radiation or neutrinos, allowing such events to be differentiated from compact object mergers occurring within the distance sensitivity limits of gravitational-wave observatories. The PBH-NS destruction scenario is consistent with pulsar and NS statistics, the dark-matter content, and spatial distributions in the Galaxy and ultrafaint dwarfs, as well as with the r-process content and evolution histories in these sites. Ejected matter is heated by beta decay, which leads to emission of positrons in an amount consistent with the observed 511-keV line from the Galactic center. © 2017 Phys.orglast_img read more

first_img Journal information: Proceedings of the National Academy of Sciences Three-dimensional shapes fill physical space in a certain way. If you pour marbles into a jar, the marbles will randomly pack within the jar. If you carefully placed every marble, layer-by-layer in the jar such that the marbles in one layer sit within the crevices between marbles on the layer below it, you can pack a few more marbles in the jar than if it was randomly packed. This will give you the highest density packing, or the least amount of space between particles. This document is subject to copyright.

Citation: Close-packing rules may not guide nanoparticle self-assembly after all (2018, January 29) retrieved 18 August 2019 from https://phys.org/news/2018-01-close-packing-nanoparticle-self-assembly.html Explore further Cersonsky et al. found that in all of polyhedral systems that they studied (FCC, SC, and BCC) the packing density was greater than the random close-packing density, which was greater than the minimal density for self-assembly. This result shows that spontaneous order does not occur because of a packing mechanism and that these systems cannot be ordered by packing. In other words, packing rules are not necessarily predictive of the ideal shapes for self-assembly even though the dense packing structure is the most thermodynamically stable structure.This paper looked at nanoparticles that were not confined. According to Greg van Anders, assistant professor of physics and co-author of the paper, “We expected that we would find that colloids would order by packing. Instead, we found that they don’t. This is particularly surprising because particles don’t pack even when the structures they form are so-called ‘close-packed’ structures.”Usually in materials science, packing rules are used to predict the optimal shape for a nanostructure, but given these results, the question becomes if, and when, packing rules can be used to predict the thermodynamically optimal shape for self-assembly.There is still some correlation between packing shape and optimal particle shape, and therefore, packing shape may be helpful in guiding predictions, but ideal packing shapes should not be the goal in nano-structure assembly. Dr. van Anders points out that this is actually good news for people trying to synthesize polyhedral nanoparticles that self-assemble into nano-structures:”After we found that the mechanism that drives the formation of structure is not packing, we realized that this might mean that perfectly-shaped particles, which pack most densely, but can be technically challenging and expensive to make, might not be the ideal shape for target structures.” More information: “Relevance of packing to colloidal self-assembly” Rose K. Cersonsky, Greg van Anders, Paul M. Dodd, and Sharon C. Glotzer, Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.1720139115 , On Arxiv: https://arxiv.org/abs/1712.02473center_img Linus Pauling applied this idea of packing density to ions, and proposed that packing principles lead to the formation of crystal structures. Nature does not like empty space, so particles should pack in the highest density or close-packed formation. In the field of materials science, colloid crystals and nanoparticle superlattices form via self-assembly of small particles in which the particles form a thermodynamically stable structure. The structures nanoparticles form are very often those found in conventional metals: face-centered cubic, simple cubic, and body-centered cubic.The theory is that packing principles guide the self-assembly of colloidal crystals. However, researchers from the University of Michigan have shown that the ordering mechanism for colloid crystals does not cause particles to self-assemble. Instead crystal assembly and packing are correlated, not causal. Furthermore, they show that packing principles may not be the best prediction tool for colloidal crystal shape. Their work appears in The Proceedings of the National Academy of Sciences.In self-assembly, a thermodynamically stable structure is formed. This structure minimizes free energy. For colloids, this frequently happens when entropy is at a maximum. However, when studying the mechanisms that guide self-assembly, researchers look at what happens at extreme conditions. At very high pressures, rather than maximizing entropy, hard particles will maximize density.To investigate the fundamental question of whether packing principles guide self-assembly, Cersonsky, et al. used modeling methods to compare three different density terms. The first is the self-assembly density, which is the lowest density where self-assembly is observed. The second is packing onset density. As the name implies, this is the lowest density where packing behavior is observed. The third term is the random close packing density, which is the maximum density that the system can be found in a disordered state.When looking at mathematical models at very high pressures (i.e., infinite pressure), there should be a boundary at which particles being to pack. The authors tested for this boundary using Maxwell relationships to define packing onset density. If the self-assembly density is found to be approximately equal to the packing onset density, then packing is likely guiding self-assembly. However, if the self-assembly density is less than the packing density, then something other than packing rules guides self-assembly. Furthermore, packing density is compared to the random close-packing density. , arXiv How particles pack in a confined space © 2018 Phys.org Shape Family and Structures.

Credit: arXiv:1804.02385 [math.CO] Journal information: arXiv The Hadwiger-Nelson problem came about when Edward Nelson and Hugo Hadwiger wondered about the smallest number of colors necessary to color all of the points on a graph, with no two connected points using the same color. Over the years, mathematicians have attacked the problem, and have narrowed the possibilities down to four, five, six or seven. Now, de Grey has eliminated the possibility of four colors as the solution.Interestingly, de Grey is well known for his work in his primary field, biology. More specifically, he has made public comments suggesting that some people alive today will live to be a thousand years old due incipient medical breakthroughs. He has established a foundation dedicated to reversing aging and continues working on the problem. His journey to math puzzle solver, he notes, has roots in his love of the game Othello. He used to be a competitive player, through which he befriended a group of mathematicians. They wound up teaching him some math theory, which he began to explore as a means of unwinding after a hard day at work.Several years later, a group of mathematicians put together the Polymath Project, a collaboration of mathematicians around the world—their online platform allows those interested in working on difficult math puzzles to collaborate with like-minded individuals. It was on that platform that de Grey found the Hadwiger-Nelson problem. He began working on it over his Christmas break, and after some time exploring the problem using the Moser spindle, discovered that one of the assumptions of prior mathematicians was wrong, and because of that, he was able to rule out four colors as a possible solution.The amateur mathematician is not taking himself too seriously though, describing his findings as “extraordinarily lucky.”last_img read more

first_imgKolkata: Amid continuing agitation at the tea gardens in north Bengal and an ongoing three-day strike over minimum wage, planters on Thursday appealed to the unions to call off the protest programmes and allow normalcy to be restored. A tripartite meeting was held on Monday in Siliguri where the state Labour Department officials outlined the progress on the issue of minimum wage. The Joint Forum of Trade Unions, an umbrella organisation of trade unions working in the tea sector, however, called the strike after the meeting to negotiate their demands on minimum wage turned out to be inconclusive. According to planters, the tea industry in north Bengal’s Dooars and Terai regions have already suffered substantial production losses during the peak season in 2018 due to frequent gate meetings in the first and second week of July. Darjeeling’s tea industry, which is in recovery mode after suffering huge losses to the tune of around Rs 500 crore in 2017 due to the 105-day strike, is in “no position to bear any further disruptions”. “Therefore, unless normalcy is restored immediately, the production and productivity would decline further,” the Consultative Committee of Plantations Association (CCPA) said in a statement. Tea producers also reiterated that the industry in West Bengal is “under severe financial stress” as tea prices over the last many years have remained stagnant and have not kept pace with the rising cost of production. “Unless price realisations and productivity improve, the industry cannot sustainably implement any further enhancement of wage. Moreover, disruptions by way of strikes and gate meetings would aggravate the situation further and make it extremely difficult for the industry to recover on the production front as well as in sustaining the expected quality of Tea made and obligations of payments in future,” the statement said. Planters also said it has to be appreciated by all stake holders that the finalisation of minimum wage is only possible after conclusion of the ongoing discussions of the Minimum Wage Advisory Committee and submission of the committee’s recommendations to the state government. As many as 11 meetings of the Minimum Wage Advisory Committee have already been held. The next meeting is scheduled to be held on August 20. Tea planters said the government has offered to examine all the pressing issues at the next meeting. Usually, wage agreement for tea workers is executed for a three-year period and the last agreement had expired on March 31, 2017. In fact, West Bengal government proposed an interim hike of Rs 17.50 to increase the remuneration from Rs 132.50 to Rs 150 with effect from January 1, 2018. Unions had protested against the “minuscule hike” in the interim measure. The state also introduced interim payment of compensation on account of savings on the procurement cost of food grains at the rate Rs 9 per day per worker from May 1, 2018.last_img read more

Watch while you walk: Try to avoid stepping into puddles and walking in rain altogether to save your feet from fungal diseases. Wash your feet afterwards and dry them as soon as you can.Pedicure: Always visit a salon which maintains cleanliness in all aspects including the tools and the products used for the treatment as these could cause fungal and bacterial infections. If you want a more pocket-friendly and a safer care routine, you could opt for home treatments. Dip your feet in lukewarm water with a drop or two of an anti-septic liquid in it for about 10-15 minutes and moisturise them after patting dry.Footwear: Sprinkle some talcum powder in your footwear to avoid infections.Clothes: Always wear a clean set of clothes since dirty clothes are a source of contamination and may lead to skin disorders when worn unclean. Similarly, wear a pair of clean socks daily.Body odour: Monsoon causes humidity after rain which leads to sweating. Thus, use anti-perspirant lotions and deodorant.

People tend to report overeating and comfort eating foods high in fat, sugar, and calories in times of stress,” said Nathalie Michels from Ghent University in Belgium. “Our findings looking at the eating habits of students during exam periods confirm this stress-induced dietary deterioration hypothesis,” said Michels, who led the study being presented at the annual European Congress on Obesity (ECO) in Glasgow, UK. Also Read – Add new books to your shelf”Our findings suggest that students have difficulties eating healthily and find themselves adopting bad eating habits, which over a few weeks can considerably affect your overall health and be difficult to change,” she said in a statement. The results are based on an anonymous online survey of 232 students (aged 19-22 years) recruited from several universities in Belgium. Before and after the month-long examination period in January 2017, respondents were asked to disclose their perceived stress and complete questionnaires that assessed changes to their dietary patterns and various psychosocial factors. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers investigated the relationship between exam stress and change in dietary quality, and whether these associations were modified by psychosocial factors such as eating behaviour, food choice motive, taste preference, impulsivity, coping strategies, sedentary behaviour, and social support. During the month-long exam period, participants found it harder to stick to a healthy diet, and only a quarter fulfilled the World Health Organization (WHO) recommended 400 grammes of fruit and vegetables a day. Students reporting higher levels of stress tended to snack more often, researchers said. The findings suggest that emotional eaters (who eat in response to negative emotions), external eaters (who eat in response to the sight or smell of food), sweet/fat lovers, people who are highly motivated by health, sensitive to reward and punishment, highly sedentary, and with higher stress levels are at greatest risk of making unhealthy food choices during this stressful time. “To fight against stress-induced eating, prevention strategies should integrate psychological and lifestyle aspects including stress management (eg, emotion regulation training, mindfulness, yoga), nutritional education with techniques for self-effectiveness, awareness of eating-without-hunger, and creating an environment that stimulates a healthy diet and physical activity,” said Michels.last_img read more

An earthquake that struck Bellevue, Washington, over two years ago turned into a wake-up call for Smooth Corp. , an operator of several e-commerce companies that sell flooring products– DIYFlooring.com , iFLOOR.com and RugArea.com .”While we had limited disruption of our operations, it made us think about what else could go wrong,” says Steve Simonson, 35, CEO and founder of the 90-employee company, which expects 2006 sales of about $80 million.As a result, Simonson says, the IT department suggested they set up backup web servers at a separate location, or “co-location facility.” This would allow continuous internet connectivity in the wake of disasters that could cause prolonged power outages, such as hurricanes or earthquakes. In May 2005, Smooth signed on with a facility in Seattle.Co-location facilities offer a secure place for companies to physically house their hardware and equipment. Most offer high security, including cameras, fire-detection and extinguishing devices, multiple connection feeds, filtered power, backup power generators and other items to ensure high availability. If necessary, the servers can run at co-location facilities for months, says Simonson, adding that these facilities “are far less vulnerable than we are.”How do you prepare for a disaster? Consider these tips from Chris Kivlehan, sales and marketing manager at INetU Managed Hosting , which offers a Business Continuity Hot Site service that places internet servers in geographically diverse data centers and synchronizes the data between the two locations according to a customized schedule. Should a crisis occur, the disaster recovery site can come online in short order and keep operations running smoothly.Establish a written policy that explains how a disaster should be handled. Says Kivlehan, “In a time of crisis, this will cut down on confusion.”Regularly review your plan to make sure it’s up-to-date.Have a backup website in place, and test it regularly. Says Kivlehan, “All you want to have to worry about in the time of a crisis is flipping the switch.”Create an “after the disaster” plan. Many people forget they may have to make some changes following a major disaster. Says Kivlehan, “Make sure [these changes are] spelled out somewhere.” Growing a business sometimes requires thinking outside the box.last_img read more

Samsung took to the U.S. Supreme Court on Monday in a last-ditch effort to pare back the more than $548 million in damages it must pay Apple for infringing the patents and designs of the iPhone.Samsung’s petition must first be accepted for review by the Supreme Court. It is the latest step in a long-running patent lawsuit between the rival companies that epitomized the global smartphone wars.Samsung Electronics paid Apple $548.2 million on Monday, fulfilling part of its liability stemming from a 2012 verdict for infringing Apple’s patents and copying the iPhone’s look.In its petition to the high court, Samsung said it should not have had to make as much as $399 million of that payout for copying the patented designs of the iPhone’s rounded-corner front face, bezel, and gridded icons.It said that awarding total profits from the sale of its devices with those designs, even if they relate only to a small portion of the phone, allows for “unjustified windfalls” far beyond the inventive value of the patents.”A patented design might be the essential feature of a spoon or rug. But the same is not true of smartphones, which contain countless other features that give them remarkable functionality wholly unrelated to their design,” Samsung told the high court.”Samsung is escalating this case because it believes that the way the laws were interpreted is not in line with modern times,” the company said in a statement.Apple did not address the new petition, but said in a statement, “We make these products to delight our customers, not for our competitors to flagrantly copy.”The South Korean electronics company’s quest to limit damages to Apple comes after the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., the nation’s top patent court, in May stripped about $382 million from the $930 million Samsung owed following the 2012 verdict. The appeals court said the iPhone’s appearance could not be protected through trademarks.Another trial over remaining damages relating to some of Samsung’s infringing products in the case is set for next spring.In its petition on Monday, Samsung also told the Supreme Court that juries should not award damages on certain “functional” aspects of designs, such as flat screens, which allow for the reading of documents, or rounded corners, which make phones easier to slip into a pocket.last_img read more

first_img If you should lose your way in the Swiss forest, don’t fret. Smart drones can probably find you.Researchers in Switzerland have developed artificial intelligence that they say is sharp enough to enable quadcopters to automatically find and follow footpaths in the woods.The new technology is specifically designed to give humans a hand in locating missing persons, an estimated 1,000 of whom send rescuers on the hunt in the woodlands and mountains of Switzerland every year.     Related: Mighty Eagles Are Being Trained to Snatch Drones From the SkyInstead of using high-tech sensors, the drone Swiss scientists deployed in their tests quickly scans hiking and mountain-biking trails, notably beneath — not above — the forest canopy, with an embedded color camera.To see the trail-stalking drone in action, check out the video below:Relying on the image-classifying deep neural network software researchers designed, the unmanned craft autonomously stays on obvious trails, automatically steering itself as it goes. Avoiding trees, twigs and brush is key, as colliding with them could easily down a drone. This ability allows it to assist in search and rescue missions, perhaps even better than humans can, researchers claim.Related: This Man Used a Drone to Walk His Golden Retriever (Video) “Interpreting an image taken in a complex environment such as a forest is incredibly difficult for a computer,” said Dr. Alessandro Giusti, a scientist who took part in the research. “Sometimes even humans struggle to find the trail!”Giusti and his colleagues, hailing from Dalle Molle Institute for Artificial Intelligence, the University of Zurich and the Swiss National Centre of Competence in Research, published their findings in the journal IEEE Robotics and Automation Letters last December.Researchers were wise to position their trail-hugging drone as a search-and-rescue helper. We can only imagine how it might eventually be used in covert forest military operations.Related: Protect Your Privacy With These Strange Anti-Surveillance Frocks and Fashions February 11, 2016 Growing a business sometimes requires thinking outside the box. 2 min readcenter_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now »last_img read more

first_imgFirefox’s new WebExtensions permission system by Martin Brinkmann on March 06, 2017 in Firefox – 14 commentsMozilla plans to turn on a permissions system for the installation of WebExtensions in the Firefox web browser that is similar to that of Google Chrome.Whenever you install an extension in Google Chrome, all of the extra permissions that the extension requests are listed in the installation prompt.The idea is to provide users with information on these extra permissions, so that abusive extensions can be avoided.The main issue with the permissions system is that most users are probably ignoring the permissions prompt. One reason for that is that it is often difficult to find out whether a permission is really needed for functionality, or if it is simply there for marketing or outright malicious purposes.Firefox’s new WebExtensions permission systemMozilla plans to launch similar installation permissions in Firefox 54 at the earliest, but most likely in Firefox 55.Firefox will display the extra permissions an extension requires during installation. The current iteration lists all permissions, but no additional information about them in the interface.The permissions come from the manifest.json file of the extension. If you open it in a plain text editor, or a special json viewer (for instance the json viewer of Firefox), you find them listed under the permissions section. This is true for Chrome and Firefox WebExtensions. Please note that you need to extract the extensions file first to get a listing of files included.Google published a page that lists all optional Chrome permissions that extensions may declare, and Mozilla published one as well. The permissions are not identical at this point in time, and it seems unlikely that they will ever be identical. Mozilla plans to support more APIs, and with that may come extra permissions that only Firefox supports.The installation prompt listing the permissions the extension requires is triggered whenever a WebExtension is installed in Firefox. This includes installations from Mozilla AMO and third-party websites, extensions that get side-loaded, and during upgrades.Firefox users who are interested in the feature can enable it right now. Please note that this landed in Firefox 53 Nightly, and that the permission does not exist by default (yet).If you run at least Firefox 53, you may do the following to enable the permission prompts when installing WebExtensions in the Firefox web browser:Load about:config in the Firefox address bar and hit the Enter-key.Confirm that you will be careful if the warning page opens.Right-click in the main area on about:config, and select New > Boolean.Name that Boolean extensions.webextPermissionPrompts.Set it to true.Any WebExtension installation afterwards triggers the installation prompt that highlights the requested permissions.The main tracking bug for the feature is 1308292. Additional information is provided on Mozilla’s Wiki website.While we are at it: check out Firefox’s permissions manager, and the new permissions system that Mozilla plans to launch.Now You: Do you find the installation prompts useful?SummaryArticle NameFirefox’s new WebExtensions permission systemDescriptionMozilla plans to turn on a permissions system for the installation of WebExtensions in the Firefox web browser that is similar to that of Google Chrome.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more

The download is offered as a web download and torrent download. It can be installed over an existing LibreOffice installation.The new version introduces changes to Mac and Linux compatibility. The minimum required version of Mac OS X to run LibreOffice 6.2.0 is Mac Os X 10.9; the next release of LibreOffice will require Mac OS X 10.10.The development team announced that 32-bit binaries for Linux will be demoted.

first_imgThere are a few different reasons why coffee makes people feel the urge to poop. (Credit: Shutterstock)You may consume coffee to get your day started, as a pick-me-up, or to get you through a lengthy meeting. You may also drink it to, perhaps, get things moving along on schedule.About 29 percent of people claim they felt the urge to poop after drinking coffee, according to a commonly cited study from 1990. But why? Discover reached out to a gastroenterology expert to see if we could get to the bottom of it.Gastroenterology is the study of the digestive system, which starts at your mouth and ends at your butt. You might see a gastroenterologist for digestive diseases such as irritable bowel syndrome, heartburn and constipation. Basically, Jonathan Rosenberg, gastroenterologist and American Gastroenterological Association expert, knows a thing or two about how we poop.Coffee, Then PoopCoffee has caffeine in it, which is a stimulant. Caffeine speeds up the squeezing motion of your gut and increases the propulsion of material through the intestine, Rosenberg says.“The same reason it keeps you awake or makes your heart beat faster, it stimulates your gut and helps you go [poop],” Rosenberg says.He and many other experts look to caffeine for why we have coffee-related poops. But, like many things in science, we haven’t yet reached consensus. After all, people don’t report on a large-scale that they feel like they have to poop after ingesting other caffeine-filled drinks like soda or energy drinks. For many people, smoking a cigarette can also give their insides a bit of a nudge. Instead, some believe the compound chlorogenic acid, which creates higher levels of stomach acid and more gastric acid, could be the culprit.Rosenberg points out that at the end of the day people respond differently to coffee. There really isn’t a sure way to tell you why, exactly, many take a dump after sipping their cup-o-joe.“If you have a routine and coffee is part of that routine, it may be your bias that you’re associating going to the bathroom after having coffee,” he says. Plus, going number two depends on hydration levels, stress levels, and the amount of exercise a person gets.One thing we do know is that we all poop, or at least we all should.last_img read more
