Cuttlefish Inspire Reflective Screens

first_img“Cuttlefish are masters of disguise, able to change their skin color in less than a second to hide from predators or draw in prey for the kill,” begins an article on MSNBC News.  A team at MIT, fascinated with the physics of this capability, tried to imitate it.  They found they could electrically control the spacing of layers of material in an artificial screen and reflect a huge range of colors.  The tuning of the material is “fantastic,” said one researcher, offering a wide variety of potential applications, such as “Electronic ink applications, pressure sensors and advertising billboards,” the article said.    For prior entries about cuttlefish, see 02/09/2005, 12/15/2006, 06/06/2007, and 12/18/2007.Better living through biomimetics – the saga continues.  The cuttlefish actually has a superior design.  The human engineers are only imitating the basic physics of reflectivity of surfaces.  The cuttlefish has exquisite control of its reflecting elements, plus built-in maintenance, plus reproduction, plus feedback response from the environment.  If humans keep trying, they might approach the capabilities of the animals.  (Notice, however, that the animals are not attempting to mimic the science or philosophy of the humans, even if your dog is named Plato.)(Visited 26 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

DevOps Booms In The Enterprise

first_imgTags:#Devops#enterprise IT#IBM#Open Source#Opscode#Puppet Labs IT + Project Management: A Love Affair Matt Asay The meek may inherit the earth, but at this rate, DevOps will inherit the enterprise. At least, that’s one lesson to take from a Puppet Labs survey of over 4,000 IT operations and development professionals. Whereas developers used to be second-class citizens within the enterprise, today they’re taking on new authority and forcing a change in mindset as to how software is developed and deployed.(DevOps, for those not in the know, is a relatively recent style of collaboration between software developers and IT departments intended to speed the deployment of new applications and services.)This enterprise shift reveals itself in a number of ways. As 451 Research analyst Jay Lyman illustrates, DevOps communities around Puppet and Chef, two of the industry’s most popular configuration management tools, have been booming, as have the commercial opportunities for Puppet Labs and Opscode, the two respective companies behind these tools. But there is one particular sign that DevOps is making waves in the enterprise, Lyman notes:Further evidence of these tools and practices going mainstream lies in expanded integration and support for Windows management and Microsoft environments, which represent a growing number of customers for CFEngine, Opscode and Puppet Labs.Small wonder, then, that Puppet Labs found a 26% increase in the rate of DevOps adoption by organizations of all sizes, compared to 2011, with 63% of organizations now indicating they use DevOps practices. This could be easily discounted — “Well, of course a DevOps-oriented vendor survey would find lots of DevOps adoption” — except that one would expect the numbers to actually be higher. Given that Puppet Labs presumably sells to the converted, why isn’t the number 100%? Presumably because even among those interested in Puppet Labs configuration management tools, the ambition to deploy DevOps practices outpaces real-world adoption of them.But that’s changing at a 26% clip. More revealingly, such DevOps adoption translates into a 75% jump in job listings: Why is DevOps reshaping enterprise IT? Quite simply, because it works. Because IT operations and development are better in collaboration than in competition. As the survey uncovered, high-performing, DevOps-savvy organizations deploy code 30 times faster with 50% fewer failures. And, strikingly, the longer DevOps practices are followed within an organization, the lower that organization’s app failure rate and the faster its recovery from failure:Source: Puppet LabsWhile some of DevOps’ rise can rightly be credited to a startup ethos and the evangelism of companies like Puppet Labs, it also gets a boost from IBM, ostensibly the most fuddy-duddy company on the planet. RedMonk analyst Donnie Berkholtz notes:IBM’s people really get it. They understand trends that are happening at the frontlines of tech today in startups and in open-source development. IBM is way out in front on enabling DevOps in big enterprises….A lot of my experience with enterprises is that they’re slow-moving and often lagging trends by years, to the point where it’s nearly laughable, but in this case IBM is definitely a front-runner.Embedded in that comment is perhaps the biggest reason for the rise of DevOps within the enterprise: it mirrors the rise of open source. Or, rather, follows it. Open source puts developers in charge of their IT. Hence, as we find a massive spike in demand for Linux professionals, and as we see the top job trends dominated by open-source technologies, we should expect DevOps to rise along with it, both in the startup and in the enterprise, with significant benefits for all.Image courtesy of Shutterstock Massive Non-Desk Workforce is an Opportunity fo…center_img Related Posts 3 Areas of Your Business that Need Tech Now Cognitive Automation is the Immediate Future of…last_img read more

Genetic study shows explosion of diversity in fish after endCretaceous mass extinction

first_img Reef fish arrived in two waves Journal information: Nature Ecology & Evolution A team of researchers from several institutions across the U.S. has found evidence suggesting that there was an explosion of diversity in fish after the end-Cretaceous mass extinction. In their paper published in the journal Nature Ecology and Evolution, the team describes their genetic study involving more than 1800 species of fish and what they found. Credit: CC0 Public Domain After the end-Cretaceous mass extinction—the one that killed off the dinosaurs—mammals became much more diverse and dominant. Without the dinosaurs to feast on them, they were free to prosper. Much less is known about what went on in the oceans. In this new effort, the researchers have added some new pieces to that puzzle.Prior research has suggested that the asteroid or comet that smashed into the Earth approximately 65 million years ago killed off more than the dinosaurs—approximately 50 percent of all species worldwide disappeared. These include many sharks and other reptiles, leaving a void of sorts in the world’s oceans that allowed fish to flourish. And flourish they did, according to the researchers with this new effort.To learn more about what happened with sea creatures after the end-Cretaceous mass extinction, the researchers collected tissue samples from 118 acanthomorph species, looking specifically at 1,000 DNA sequences that were similar across the genomes of their samples—as part of that effort, they searched for variations in genetic sequences that offered clues regarding how closely related the fish were to one another.The researchers found that six large groups of fish originated over the course of 10 million years after the mass extinction. Of those groups, five were acanthomorphs (spiny-rayed fish). Today, there are approximately 18,000 members of the acanthomorphs species and they represent approximately one in three vertebrate species alive today. That so many of them originated in the time after the dinosaurs disappeared shows that they, like mammals, found the world a much friendlier place—one where they were allowed to prosper. Such an explosion suggests that sharks and other reptile populations and their diversity must have plunged, leaving a vast void for the acanthomorphs to fill. Still unclear is why acanthomorphs, rather than other fish species, became so dominant. This document is subject to copyright.

Explosive diversification of marine fishes at the Cretaceous–Palaeogene boundary, Nature Ecology & Evolution (2018). DOI: 10.1038/s41559-018-0494-6AbstractThe Cretaceous–Palaeogene (K–Pg) mass extinction is linked to the rapid emergence of ecologically divergent higher taxa (for example, families and orders) across terrestrial vertebrates, but its impact on the diversification of marine vertebrates is less clear. Spiny-rayed fishes (Acanthomorpha) provide an ideal system for exploring the effects of the K–Pg on fish diversification, yet despite decades of morphological and molecular phylogenetic efforts, resolution of both early diverging lineages and enormously diverse subclades remains problematic. Recent multilocus studies have provided the first resolved phylogenetic backbone for acanthomorphs and suggested novel relationships among major lineages. However, these new relationships and associated timescales have not been interrogated using phylogenomic approaches. Here, we use targeted enrichment of >1,000 ultraconserved elements in conjunction with a divergence time analysis to resolve relationships among 120 major acanthomorph lineages and provide a new timescale for acanthomorph radiation. Our results include a well-supported topology that strongly resolves relationships along the acanthomorph backbone and the recovery of several new relationships within six major percomorph subclades. Divergence time analyses also reveal that crown ages for five of these subclades, and for the bulk of the species diversity in the sixth, coincide with the K–Pg boundary, with divergences between anatomically and ecologically distinctive suprafamilial clades concentrated in the first 10 million years of the Cenozoic. © 2018 Citation: Genetic study shows explosion of diversity in fish after end-Cretaceous mass extinction (2018, March 13) retrieved 18 August 2019 from read more

Applying deep learning to motion capture with DeepLabCut

first_img Citation: Applying deep learning to motion capture with DeepLabCut (2018, August 23) retrieved 18 August 2019 from © 2018 Tech Xplore More information: Alexander Mathis et al. DeepLabCut: markerless pose estimation of user-defined body parts with deep learning, Nature Neuroscience (2018). DOI: 10.1038/s41593-018-0209-yAbstractQuantifying behavior is crucial for many applications in neuroscience. Videography provides easy methods for the observation and recording of animal behavior in diverse settings, yet extracting particular aspects of a behavior for further analysis can be highly time consuming. In motor control studies, humans or other animals are often marked with reflective markers to assist with computer-based tracking, but markers are intrusive, and the number and location of the markers must be determined a priori. Here we present an efficient method for markerless pose estimation based on transfer learning with deep neural networks that achieves excellent results with minimal training data. We demonstrate the versatility of this framework by tracking various body parts in multiple species across a broad collection of behaviors. Remarkably, even when only a small number of frames are labeled (~200), the algorithm achieves excellent tracking performance on test frames that is comparable to human accuracy. As Wei and Kording note, scientists have been trying to apply motion capture to humans and animals for well over a century—the idea is to capture the intricacies of all the tiny movements that together make up a larger, more noticeable movement, such as a single dance step. Being able to track such movements in animals offers some clues regarding their biomechanics and how their brains work. Being able to do so with humans can aid in physical therapy efforts or improvements in sports performance. The current process involves video recording the subject and carrying out a laborious process of tagging images frame by frame. In this new effort, the researchers have developed a computer automation technique to carry out the process, making it much faster and easier.To create DeepLabCut, the group trained a neural network using information from a database called Imagenet that contains a massive number of images and associated metadata. They then developed an algorithm that optimized estimations of poses. The third piece was the software that runs the algorithm, interacts with users and offers output of results. The result is a tool that can be used to perform motion capture on humans and virtually any other creature. All a user has to do is upload samples of what they are after, say, pictures of a squirrel, with its major parts labeled and some videos demonstrating how it moves in general. Then the user uploads video of a subject doing an activity of interest—say, a squirrel cracking open a nut. The software does the rest, producing motion capture of the activity. The team has made the new tool freely accessible to anyone who wishes to use it for whatever purpose they choose. Wei and Kording suggest the tool could revolutionize motion capture, making it easily available to professionals and novices alike. The hand of a mouse is automatically tracked with DeepLabCut, and the trajectories show the future (left) and past (far right) movements.
