Skyrmion reshuffler comes to the aid of stochastic computing

first_img Explore further One of the main advantages of stochastic computing is its error-tolerance. If one bit in a string becomes flipped, then in the traditional computing scheme that minor error completely changes the value of the encoded data. In stochastic computing, however, a flipped bit only slightly changes the probability of finding a 1, and in a sufficiently long bitstream the effect is negligible. This advantage becomes especially important when electronic devices are scaled down to the point where errors become more frequent, resulting in the need for error-correcting codes in traditional computing.A stochastic computing device can perform arithmetic with p-values, but, due to the way these calculations are implemented, the device often does not give the correct answer when the two input bitstreams are identical—that is, when they have the same 0’s and 1’s in exactly the same order. To address this problem, the signals must be reshuffled while conserving the p-values. Although reshuffling signals can be done using pseudo-random number generators, these require large memories and consume large amounts of energy. The skyrmion reshuffler uses orders of magnitude less memory and energy than these devices, suggesting that it may offer a low-energy, high-efficiency solution to this problem. Skyrmion neuronThe researchers also showed that, with some modifications, the skyrmion reshuffler can function similarly to a biological neuron. When a neuron receives electrochemical signals from other neurons, it integrates the incoming activity and, if the activity is sufficiently high, it sends out a voltage spike of its own. Neurons are also “leaky” in the sense that, when they do not receive signals, their voltage slowly decays over time.Similarly, when the “skyrmion neuron” receives a bitstream of skyrmions as input, it accumulates the skyrmions in one of its chambers, and then sends out a reshuffled bitstream. Moreover, when skyrmions are crammed together too tightly, they begin to annihilate, emulating a leaky neuron.The researchers expect that both the skyrmion reshuffler and skyrmion neuron may one day serve as the building blocks of future spintronic stochastic computers. “The skyrmion reshuffler is actually a very versatile device,” Pinna said. “On top of reshuffling telegraph noise signals (or, equivalently, bitstreams), it can also be used to generate bitstreams with well-defined p-values. In fact, by injecting skyrmions in specific ratios in the device’s two chambers, the device effectively takes an imposed p-value as input and outputs a scrambled stream of skyrmions defining it. Although this is probably more efficient to implement with super-paramagnetic tunnel junctions, it does turn out to be pretty elegant that the same device can be used to both scramble and generate random bitstreams. “The skyrmion neuron is a smaller tassel in the big picture of neuromorphic techniques in magnetism. It is of great interest to study all the ways we can functionally reproduce a neuron’s behavior in condensed matter systems. The philosophy behind it is that one can then attempt to construct analog neural networks bottom-up by coupling many such elements together.” A stochastic computing device multiplies the p-values of two input signals using an AND gate. (a) The result is accurate when the two signals are not correlated, but (b) inaccurate when the signals are correlated. (c) After the signals have been reshuffled, they are no longer correlated but still have the same p-value, resulting in a better approximation.

In stochastic computing, on the other hand, data is encoded in bitstreams of random 0’s and 1’s where the order does not matter. Instead, the important thing is that the probability of finding a 1 in any given position in the bitstream, i.e., the p-value, corresponds to the value of the data being encoded. Researchers have designed a “skyrmion reshuffler”—just as a card shuffler shuffles a deck of cards, the skyrmion reshuffler does the same with a type of quasiparticle called magnetic skyrmions. The reshuffler is the first low-energy, compact device that can reshuffle signals of any kind (skyrmions, electrons, etc.) with a high efficiency, which may enable it to address one of the long-standing challenges facing an alternative type of computing called stochastic computing.

Credit: Pinna et al. ©American Physical Society Meet the skyrmions—exotic quasiparticles could revolutionise computing The researchers, Daniele Pinna and coauthors from the University of Paris-Saclay, have published a paper on the new method of manipulating skyrmions for stochastic computing in a recent issue of Physical Review Applied.Skyrmions in two dimensionsMagnetic skyrmions are tiny defects in a magnetic field where the magnetic field is reversed. One of their interesting properties is their ability to move freely along the two-dimensional surface of the magnetic field. When many skyrmions come together, their high mobility causes them to act as a freely moving gas in two dimensions. In recent years, magnetic skyrmions have captured the attention of researchers because their tiny size (roughly 10 nm) and high mobility suggest that they have the potential to serve as information carriers for future miniaturized, high-speed, low-energy devices. So far, however, most of the work in the emerging field of skyrmionics has used skyrmions in one-dimensional tracks, rather than taking advantage of their full two-dimensional freedom.The skyrmion reshuffler presented in the new study is one of the first devices to harness the dynamics of skyrmions as a two-dimensional gas. The reshuffler receives an input stream of skyrmions and thermally reshuffles their order, while still maintaining the same skyrmion states as in the original stream. That is, if the skrymions were encoding data using 0’s and 1’s, then both the input and output bitstreams would have the same number of 0’s and 1’s. Consequently, the probability of finding a 1 (referred to as the p-value in this context) would be the same in either bitstream, meaning that the p-value is conserved. As it happens, reshuffling while conserving p-values is exactly what’s needed to perform certain operations using an alternative type of computing called stochastic computing. “The greatest significance of this work is, in my opinion, having rid skyrmions from the 1-D shackles they have been forced to live in,” Pinna told Phys.org. “At every magnetism conference, research work on skyrmions preambles with their potential use for racetrack memory applications. [But] skyrmions are intrinsically 2-D objects with extremely interesting mobility and spatially extended properties. My work (past and current) attempts to design, theorize and demonstrate novel devices in the realm of unconventional computing where I firmly believe that nanomagnetism and spintronics can pave the way for the development of scalable and energy-efficient analog computational devices.” Citation: Skyrmion reshuffler comes to the aid of stochastic computing (2018, July 6) retrieved 18 August 2019 from https://phys.org/news/2018-07-skyrmion-reshuffler-aid-stochastic.htmllast_img read more

New Research From Clinical Psychological Science

first_imgWeaker Memory Performance Exacerbates Stress-Induced Cannabis Craving in Youths’ Daily LivesRobert Miranda, Jr., Stephanie E. Wemm, Hayley Treloar Padovano, Ryan W. Carpenter, Noah N. Emery, Joshua C. Gray, and Ethan H. Mereish Heterogeneity of the Anxiety-Related Attention Bias: A Review and Working Model for Future ResearchTracy A. Dennis-Tiwary, Amy Krain Roy, Samantha Denefrio, and Sarah Myruski The Influence of Stress on Depression and Substance Use Problems Among Young Male Same-Sex Couples: Relationship Functioning as an Underlying MechanismBrian A. Feinstein, Elizabeth McConnell, Christina Dyar, Brian Mustanski, and Michael E. Newcomb Read about the latest research published in Clinical Psychological Science: Most of the past research on suicidal thoughts and behaviors (STBs) relied on long follow-ups and examined risk factors in isolation when predicting suicide is more complex. To address whether these methodological constraints have the ability to predict suicide risk, the researchers recruited a large sample of individuals worldwide who were at elevated risk of STBs, evaluating them in a first session and again 3, 14, and 28 days later. The researchers also used machine-learning algorithms to examine the complexity underlying suicide risk. Results indicated that machine-learning algorithms were better than individual follow-ups at predicting STBs. Some predictive factors such as suicide ideation, were already strong predictors in more standard analyses, but complex models in this research were a way to better predict imminent suicidal thoughts and nonfatal suicide attempts. Taken together, these findings support the use of complex models and inclusion of artificial intelligence in clinical decision making. This study examined the interaction of stress, reminders of cannabis use, and craving for the drug among adolescents and young adults. Miranda and colleagues recruited participants who used cannabis at least twice weekly and reported at least one symptom of cannabis abuse. At the beginning of the study, participants performed a memory-for-words test that captured working memory performance.  Then, over 4 to 14 days, they were prompted on their mobile devices every 3 hours to report their cannabis cravings, consumption, current levels of stress, and presence of cannabis-related stimuli in their environment (e.g., presence of drug paraphernalia, interactions with people they frequently smoked marijuana with). Individuals reported stronger craving in the evenings and late night relative to the morning, in the presence of other cannabis-related stimuli, and when experiencing more interpersonal stress. Importantly, individuals with weaker working memory performance experienced stronger craving when their stress was heightened than individuals with stronger working memory performance. However, working memory performance did not affect the association between cannabis-related stimuli and craving. These findings indicate that stronger working memory may protect individuals from craving cannabis at stressful moments. Predicting Imminent Suicidal Thoughts and Nonfatal Attempts: The Role of ComplexityJessica D. Ribeiro, Xieyining Huang, Kathryn R. Fox, Colin G. Walsh, and Kathryn P. Linthicum To examine the associations between stress and health (including depression and substance use) among male same-sex couples, Feinstein and colleagues analyzed data from an ongoing longitudinal study on HIV and substance use among gay, bisexual, and other men who have sex with men. Participants completed measures of perceived stress, internalized stigma (e.g., fear of coming out), microaggressions (e.g. someone expressing a stereotype, such as “Gay men are so good at fashion”), victimization (e.g., being physically assaulted), outness, depression, alcohol-use problems, marijuana-use problems, and relationship functioning (i.e., satisfaction, trust, and commitment). Results indicated that when a member of the couple reported internalized stigma and microaggressions, relationship interactions were more negative and were linked with greater depression and alcohol abuse. These findings suggest that individual stress might increase conflict within a relationship. Results also highlight the importance of considering general stress as a risk factor for negative health outcomes among male same-sex couples. Relationship education and interventions focused on sexual minority individuals and same-sex couples may be enhanced by showing them strategies to cope with stress and understand how their relationship quality influences health, Feinstein and colleagues propose. Anxiety-related attention bias (AB) is characterized by selective or exaggerated attention toward threatening information and seems to be a concept with different aspects and with complex relationships with anxiety. In this review, Dennis-Tiwary and colleagues propose a working model of AB that incorporates subtypes and variability. They say AB should no longer be considered solely a tendency to focus attention on a threat instead of away from it. Behavioral and neurophysiological research indicates, for instance, that AB toward threat is associated with distress-related disorders, such as generalized anxiety disorder. Meanwhile, AB away from threat is associated with fear-related disorders, such as phobias. According to this threat-discrimination and cognitive-control model of AB, four subtypes of AB heterogeneity can be identified: (a) labile, characterized by low threat-safety discrimination (TD; ability to discriminate between safe and threatening cues) and low cognitive control (CC), with high variability in AB; (b) vigilant, characterized by high TD and low CC, with a bias toward threatening information; (c) avoidant, characterized by high TD and high CC, with a bias away from threatening information; and (d) no bias, characterized by low TD and high CC. The authors propose that this model can lead to personalized interventions for anxiety disorders, with treatment tailored to an individual’s AB subtype.last_img read more

Water sports may expose you to antibioticresistant bacteria

first_imgLove to play water sports like surfing or bodyboarding? Beware, you may be three times more likely to swallow antibiotic-resistant Escherichia coli or E.coli bacteria in your guts, new research has revealed. Surfers were found to swallow ten times more sea water than sea swimmers, making them more vulnerable to E.coli bacteria.Regular surfers were also found four times as likely to harbour bacteria that contain mobile genes that make bacteria resistant to the antibiotic. Also Read – Add new books to your shelfThis is significant because the genes can be passed between bacteria – potentially spreading the ability to resist antibiotic treatment between bacteria, the researchers said. “Antimicrobial resistance has been globally recognised as one of the greatest health challenges of our time, and there is now an increasing focus on how resistance can be spread through our natural environments,” said Anne Leonard, from the University of Exeter. Scientists compared faecal samples from 300 surfers and non-surfers to assess whether the surfers’ guts contained E.coli bacteria that were able to grow in the presence of cefotaxime. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe study, published in the journal Environment International, found that 13 of 143 (9 per cent) of surfers were colonised by these resistant bacteria, compared to just four of 130 (3 per cent) of non-surfers swabbed.A treatment with cefotaxime – a commonly used and clinically important antibiotic previously prescribed to kill off E.coli bacteria – showed that the bacteria has acquired genes that enable them to survive this treatment, the study showed.According to the 2016 O’Neill report commissioned by the UK government, antimicrobial resistant infections could kill one person every three seconds by the year 2050 if current trends continue.There is an urgent need to curb antibiotic-resistance or else we may be entering an era in which antibiotics are no longer effective to kill simple, and previously treatable, bacterial infections, warned the World Health Organization.last_img read more

Kyrie Irving is officially injuryprone

first_imgTiger is the most powerful athlete of this generationTiger Woods Masters return is expected to draw massive ratings as viewers tune in to see if Woods can win another green jacket after most thought he was finished. Even after years out of contention, Tiger is still far and away the most popular golfer on tour and moves the needle like no other.Unlike icons in other sports who were eventually replaced by other stars, no golfer has come close to filling Woods. In terms of impact on a sport, Woods is the most powerful athlete of this generation.

Apples iPhone 4S Announcement Disappoints

first_img Opinions expressed by Entrepreneur contributors are their own. Apple’s unveiling of its newest iPhone on Tuesday disappointed some who were looking for a major technology upgrade for the device. The chief hardware innovations of the iPhone 4S (not the iPhone 5 some were expecting) are its voice-command capability and better camera — not exactly market-changing improvements.While those are helpful advances for those who use Apple’s smartphone in the field, most business users will likely see more of an impact from changes to the iPhone’s wireless service availability, and from new prices across the entire iPhone line.The iPhone 4S has a smarter processor that allows it to be used on a wider variety of networks, including that of Sprint Nextel, which will sell and host an iPhone on its network for the first time. Apple says the iPhone 4S will be available for use by networks in 70 countries by the end of the year – what it called its fastest global rollout for any iPhone version. min read That’s a plus for business users who travel overseas and want to use their favorite apps while there. And obviously, entrepreneurs who have a Sprint account can now use the iPhone to boost productivity without having to change providers.Still, most of the iPhone’s most-advanced features are not much use in countries such as India, which have been slow to roll out the kind of high-speed networks those features need. This is partly why Apple has only a tiny fraction of the market in India, which according to data researcher IDC has the world’s second-most wireless subscribers, with more than 600 million.For small business owners in the U.S., Apple’s new pricing scheme is worth noting, as it makes older models available at either nominal prices or, in the case of the iPhone 3GS, free.The new iPhone 4S is priced beginning at $199 for a 16-Gigabyte version, which is plenty except for those who like to put a lot of songs and video on their phones. A 32-Gigabyte version will cost $299 at introduction, and a 64-Gb version, $399.Meanwhile, the older iPhone 4, with 8 Gigabytes of storage, will be priced at just $99 if you sign up for a two-year contract with Sprint, AT&T, Verizon Wireless, or any other provider who sells the device. Even better for those who don’t want to pay for the leading edge of Apple technology, an even older model, the iPhone 3GS, will come free with a two-year contract.The pricing moves are a strong argument to not buy the most recent iPhone version but instead choose an older model, as I did in August when I purchased an iPhone 3GS for $49 plus tax. The device has already boosted my productivity, even though I’m an independent contractor who uses it primarily to email, call and surf the web.Even more gains are being realized by businesses who regularly use a broader range of apps, such as Evernote (to get organized), Square (to accept payments) and Print n Share (for on-the-go printing).Apple’s new voice-activated personal assistant software, called Siri, may yet turn out to be a hit among mobile users. For now though, if you’ve been waiting to try the iPhone platform, Apple just provided some inexpensive ways to do so – just not with its newest phone.The iPhone 4S will be available Oct. 14 in the U.S.Will you buy an iPhone 4S?

Is Your Companys Data Safe in the Cloud Infographic

first_img At this point it probably goes without saying that cloud services are becoming crazy popular. So much so, more than half of all U.S. businesses use some form of it. Whether managed internally or contracted to a third party like Google or Amazon, cloud services allow businesses to manage their information and files in one location that’s easy to access and secure.But exactly how secure is the cloud? Even if your IT staff or service provider is vigilantly securing your cloud with the latest safety measures and security systems, cloud storage can still be risky business. Everything is hackable. Nothing is breach-proof.Related: Why You Shouldn’t Be Afraid of the CloudTech giant Dell recently surveyed 200 IT managers in the United Kingdom about their use and understanding of the cloud. Based on the results, the company put together the infographic below, which looks at three critical areas of cloud security: Virtual Private Networks (VPN, which allows a computer or a Wi-Fi-enabled device to send and receive data securely across a shared or public network), bring your own device (BYOD) policies and a Domain Name System (DNS, the system that Internet domain names and addresses are tracked and regulated by).So, the question is obvious: How safe is your cloud?Click to Enlarge+ Related: Why Uncovering a Network Security Breach Can Take Weeks or Months November 5, 2014 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.center_img 2 min read Register Now »last_img read more

15 Tips for Succeeding as an Independent App Developer

first_img Register Now » Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 5 min read How can you succeed as an independent app developer when there is already more than a million apps in the Apple and Google Play App stores? Having interviewed more than 300 app entrepreneurs, I’ve rounded up the best tips from some of the most successful indie app developers to help you find success in today’s ever-changing mobile app space.1. Study the bad apps.Klicktock’s Matt Hall, the developer behind Crossy Road, suggests that you study not just the successful apps, but the horrible ones, too. Ask yourself what the app did wrong and make sure you don’t duplicate that same mistake.Many people only study the top of the charts. Studying the bottom of the charts, however, will help you realize what not to do.Related: A Step-by-Step Guide To Building Your First Mobile App2. Increase output, decrease time.Focus on creating simple apps that can be published in roughly six to eight weeks. This allows you to test many different ideas and create a portfolio of apps, which in turn will increase your likelihood of success.3. Design is everything.Philipp Stollenmayer, from kamibox, had two of his games featured by Apple in consecutive weeks and says, “design is everything.” Clean, flat, iOS 8 design with a good app name and a superbly designed icon increases the likelihood that Apple will feature you.4. Build something you are passionate about.Build something that you want to solve with such immense conviction that the energy that you put into it will shine through and kick start the early traction and positive reviews.It’s important to treat yourself as the most important user of the app. This internal driver should compel you to create something amazing. Remember, some of the top developers would still be creating apps even if they didn’t get paid.5. Invalidate your idea.As contradictory as it sounds, be passionate but don’t fall blindly in love with your idea. Research the competition and do a thorough analysis of the market to make sure it’s something worth building.Don’t focus exclusively on research that supports your idea. Look for reasons why the app is a bad idea.Related: 5 Development Mistakes That Can Destroy Your Mobile App6. Create something simple.It’s important to get ease of use just right and have the app do things that will simply delight users. Your goal is an app you can hand to someone who has no clue what the software does but within seconds they figure out how it works.7. Be persistent.The most notable successes took at least ten years — they weren’t overnight achievements. Be passionate about what you are making. Stay persistent and continually learn with each new version update and each new app published.8. Don’t seek investment.Dan Counsell, founder of Realmac Software, suggests that indie developers should not seek investors but instead “build it in their spare time, be independent and most of all build something useful.”9. Find a technical partner.It’s all about having a small core team that is literally in the same room with you. Having a technical co-founder allows you to bootstrap a minimum viable product to the market with someone who is invested in the idea. People with great ideas don’t always have deep pockets.10. It’s not too late.Focus on solving a problem, designing the solution well and somehow making someone’s day more enjoyable or easier. It’s not too late to find success in the app stores.Related: 5 Questions to Ask Before Developing a Mobile App11. Do one thing well.Focus on doing one thing really, really well. Make sure that one thing is substantial and meaningful to a lot of people. Don’t try to be everything to everyone. Don’t try to solve a problem that doesn’t exist for real people. The best apps solve everyday problems for people.12. Don’t overlook distribution.Distribution is a big challenge for any app. You can build a phenomenal product, but still have difficulty getting it to users. Figure out where your users are and get in front of them.13. Be clear about your goals.Carter Thomas of Blue Cloud Solutions, suggests that you “sit down for a day or two and be honest about why you are getting into the mobile space.”Whether you want to develop an app that changes the world or create a portfolio of apps that allows you to leave your corporate job, having a clear goal in mind will help you find the right direction to take in the app store.14. Just start.Dhanush Balachandran, founder of Sortly, suggests that if you’ve been thinking about building apps to “just do it.”Don’t overthink the initial process. The experience of building your first app and getting it in the app stores is by far the most important thing. The process of submitting an app and getting approved is complicated, so start with something simple and get that experience under your belt.15. Believe in your idea.There’s not a lot of difference between a really good idea and a really bad one. If it’s a great idea, but no one has thought of it, people might think it’s a little off at first. Do your homework on the idea, take a long look in the mirror and think about what you are really willing to invest in this idea. Then, jump in with both feet and assume success.Related: How to Survive Your First 100 Days of App Development Opinions expressed by Entrepreneur contributors are their own.
