Latest in Robotics Shuffle Twists Turns 90°

first_img Professor Masanao Koeda affiliated with Ritsumeikan University has developed a robot measuring nearly 20 inches that can shuffle its feet, twist and bend. The robot can make a 90° turn without taking its feet off the ground. According to Digital World Tokyo, this breakthrough will allow future robots ease in motion without losing balance and falling. Currently, two legged robots must perform a circular turn likened to an oil tanker to change course.A video of the robot performing the “Koeda Shuffle,” is available here. The significance of this advancement is that the shuffling action will allow robots in the future to maintain balance while carrying objects in its arm-like extensions. The ability to shuffle its feet in one spot and make a turn is a major achievement that holds significant potential for the utility of future robots.The current method requiring the robot to lift one foot and in rapid succession balance on one foot to perform a change in direction can impede balance. It is difficult for the robot to perform arduous turns and hold objects in its hands. The shuffling action of the Koeda Robot allows the robot to change directions without having to pick up it feet in the process. This factor allows increased balance and smooth, non-jerking motions which will afford the robot greater agility carrying objects while in motion. The accomplishments of Dr. Koeda in collaboration with T. Yoshikawa and K. Nakagawa and others in the field of robotics has achieved scientific recognition. Recently an abstract on “Stability Improvement Using Soft Sole on Humanoid Robot” was presented at The 9th International Conference on Climbing and Walking Robots. Other noteworthy scientific abstracts include, “Grasping and Manipulation by Soft Fingered Robot Hands,” and “A Quantitative Evaluation Method of Handiness Using Haptic Virtual Reality Technology.” Professor Koeda has an impressive scientific background in the field of robotics, communications and innovations in unmanned helicopters used in assessing damage in natural disasters. His collaborative efforts in this area was conducted for the United Nations World Conference on Disaster Reduction. His current work on the prototype shuffling, twisting and turning robot is a logical extension of his scientific endeavors. The future of the agile humanoid robot include modifications that will allow it to move on rough surfaces and sloped land areas. The ultimate future of the humanoid robot may include the role of caretaker for severely disabled or wheel chair bound human counterparts. The range of duties and tasks the Koeda Robot may handle in the future is by all estimates up to the imagination of the Koeda team of scientific explorers.

More than 21 percent were PayPal accounts. This brings a total of almost 298,000 unique credentials that were intercepted from over 52,000 infected machines.Torpig’s secret behind siphoning data from computers is by infecting programs such as Mozilla Thunderbird, Microsoft Outlook, Skype, ICQ, and other applications, by monitoring every keystroke. Every 20 minutes, the malware automatically uploads new data to servers. The software is then able to intercept passwords before they may be encrypted by secure sockets layer or other programs.The security researchers were able to hijack the botnet after discovering weaknesses in the way it updates the master control channels that are used to send new instructions to the infected computers. A technique know as domain flux sporadically generates a large list of domain names of computers to report to but only uses one address, ignoring all the others.The researchers were able to monitor the botnet’s behavior over a period of 10 days by registering one of the domain names on the list and seizing control of the machine. The hijackers eventually gain back control of the machine by using a backdoor built into the infected computer.In all researchers counted over 180,000 infected computers that connected from 1.2 million IP addresses. Torpig gains control of a computer by rewriting the hard drive’s master boot record. As a result, control of a computer is gained during the early stages of a PC’s boot process, allowing it to bypass anti-virus and other security software.© 2009 PhysOrg.com This document is subject to copyright.

Through his company Global Research Technologies, based in Tucson, Lackner has built an early model and hopes to have a fully working prototype within three years.As Lackner explains, the technology is similar to that used at coal plants to capture carbon from flue stacks, but can be used anywhere. Lackner notes that half of carbon emissions come from small sources, including cars and airplanes, and is usually nearly impossible to collect. But since the carbon dioxide in the air is actually very concentrated, the device required to collect it can be fairly small. Lackner’s goal is to make the synthetic tree highly efficient for its size. Compared to the amount of carbon dioxide that a large windmill can avoid generating, for example, a synthetic tree of equal size could collect several hundred times the amount of carbon dioxide that the windmill avoids. Each synthetic tree would cost about $30,000 to build, with most of the cost due to the technology used to release the carbon dioxide from the sorbent. In addition, since the device requires energy to operate, it also generates some carbon itself if plugged into the power grid. Lackner calculated that, for every 1000 kg of carbon dioxide the synthetic tree collects, it emits 200 kg, so that 800 kg are considered true collection.via: CNet News© 2009 PhysOrg.com First Successful Demonstration of Carbon Dioxide Air Capture Technology Achieved A synthetic tree could collect carbon coming from small, distributed sources, which is usually very difficult to collect. Credit: Global Research Technologies. (PhysOrg.com) — Scientists have designed a synthetic tree that traps carbon dioxide from the air in an attempt to combat growing emissions. The device looks less like a tree and more like a small building, but it can collect carbon about 1,000 times faster than a real tree. One synthetic tree could absorb one ton of carbon dioxide per day, an amount equivalent to that produced by about 20 cars, on average. After being trapped in a chamber, the carbon would be compressed and stored in liquid form for sequestration.last_img read more

Microsoft streaming storage patent maps OS future

first_img(PhysOrg.com) — Microsoft might be planning a future where Windows open to something far bigger, the next time you push your power button on. A patent filed by Microsoft points to its plan for an operating system environment beyond Windows 8 that depends on cloud computing, not locally installed software. The patent suggests your computer will be booted through remote storage in a cloud computing construct, where software services control your digital work.

The patent says:“Various aspects of the subject matter described herein are directed towards a technology by which a virtual storage device for a physical or virtual computing machine is maintained as a chain of data structures (e.g., files) including far data maintained at a far (e.g., remote) backing store and near data maintained at a near (e.g., local) backing store (which initially may be empty).”Reports in ConceivablyTech and Geek.com detail the patent, filed in February 2010, but which are surfacing now.The patent 20110197052 is called “Fast Machine Booting Through Streaming Storage.“ Inventors’ names are listed as Dustin Green, Jacob Oshins, and Michael Neil.One of the advantages is called out as fast booting time.“Described is a technology by which a virtual hard disk is maintained between a far (e.g., remote) backing store and a near (e.g., local) backing store, which among other advantages facilitates fast booting of a machine coupled to the virtual hard disk,” says the patent. The patent explains that “the virtual disk is available for use immediately, rather than needing to download an entire operating system image before booting from that downloaded image. For example, during a boot operation, only a relatively small amount of data is needed from the boot disk, which is available from the far data and/or the near data.”News of the patent is seen as proof that rumors and tips over Microsoft’s research project Midori back in 2008 and 2009 were on to something big. Midori, an operating system project at Redmond, was believed to be focusing on the company’s OS future directions and a path to integration with Azure, which is Microsoft’s cloud platform.The patent’s details and intent will most likely be the subject of conversation in the corridors if not meeting places next month in Anaheim, at the sold-out Microsoft BUILD conference for developers.

Through a nanopore ionically Graphene quantum transistor for nextgeneration DNA sensing

first_img © 2013 Phys.org. All rights reserved. Journal information: Proceedings of the National Academy of Sciences Prof. Jean-Pierre Leburton briefed Phys.org on the research he and his colleagues – Anuj Girdhar, Chaitanya Sathe and Klaus Schulten – conducted. “Simulations are presently leading experimental efforts on this specific topic – but transport models based on density functional theory cannot handle a large number of atoms due to limited computational resources,” Leburton tells Phys.org, recounting some of the challenges the scientists faced. (Density functional theory, or DFT, is a quantum mechanical modeling method used in physics and chemistry to investigate the electronic structure of many-body systems.)”In addition,” Leburton continues, “these models are restricted to solid-state systems, while we’re dealing with a hybrid solid-liquid system. For this reason, very simplistic and idealistic physical conditions are assumed on graphene nanoribbons.” Such assumptions include uniform GNR widths with perfect armchair or zigzag edges, the nanopore being placed in the center of the graphene nanoribbon, and an absence of electrostatic perturbations from either the electrolytic solution or the dielectric supporting the graphene nanoribbon.”In our approach, we use a multiorbital tight-binding (TB) technique that can handle a much larger number of atoms than DFT to account for the non-uniform GNR width, its irregular edges, and various sizes and positions of the nanopore,” Leburton explains. (The TB technique uses a superposition of wave functions of isolated atoms located at each atomic site to calculate the electronic band structure of solids.)”The electronic spectrum obtained from the tight binding model is then fed into a transport model based on a non-equilibrium Green function technique to compute the electrical conductance in general GNR configurations.” A non-equilibrium Green (aka Green’s) function, or NEGF, can be used to solve an inhomogeneous differential equation with boundary conditions in a way that is roughly analogous to the use of Fourier series in the solution of ordinary differential equations. Over the last decade, NEGF techniques have become widely used in corporate, engineering, government, and academic laboratories for modeling high-bias, quantum electron and hole transport in a wide variety of materials and devices.

These additional electrodes will have the dual purpose of controlling the lateral and vertical motion of the DNA molecule during its translocation through the nanopore. By so doing, the scientists expect to reduce the jitter and flossing due to thermal motion of water molecules and ions in the solution, and thereby improve the identification of each nucleotide when it passes in front of the detecting graphene layer.”One of the major features of our model was to assume that the DNA passes through the nanopore rigidly,” Leburton continues. “Aside from improving our multi-scale approach, the next steps in our research will consist of implementing our computational model by including the thermal motion of the DNA through molecular dynamic simulation; the proximity effects of dielectrics sandwiching the detecting graphene layer; the effect of the gate on the GNR conductance for enhanced detection performances; the electrostatic effects of additional controlling electrodes on the DNA molecular dynamics; and determining the optimum membrane design for high sequencing performances.”Regarding other areas beyond genomics that might benefit from their study, Leburton says, their research will also contribute to the development of novel miniaturized bioelectronic devices with broad range of applications in personal medicine. “Indeed,” he illustrates, “if solid-state membranes can be energized electronically, one can imagine them performing similar functions as biocells, but with electrical stimulation, control and detection. This would open the door to new practices in portable in situ bioanalysis without the need for costly and time-consuming lab analysis. In a more general context,” he concludes, “the interaction of biology and nanoelectronics at the molecular level – with the possibility of manipulating biological information by nanoscale electronic devices – opens new horizons in information processing technology by taking advantage of the biological capability of storing huge amount of information, on the one hand, and the ability of semiconductor technology to process it quickly, reliably and at low cost, on the other.” Schematic diagram of a prototypical solid-state, multilayer device containing a GNR layer (black) with a nanopore, sandwiched between two oxides (transparent) atop a heavily doped Si back gate, VG (green).

(Phys.org) —In the ongoing quest to devise faster, lower-cost methods for sequencing the human genome, scientists at University of Illinois at Urbana–Champaign have developed a novel approach: DNA molecules are sensed by passing them through a layer of constricted graphene embedded in a solid-state membrane containing a nanopore (a small hole with a roughly 1 nm internal diameter), located in a graphene nanoribbon (GNR). A critical feature of the new paradigm is that graphene’s electrical properties allow the layer to be tuned in several distinct ways – namely, altering the shape of its edge, carrier concentration and nanopore location – thereby modulating both electrical conductance and external charge sensitivity. The researchers found that their novel technique can detect the DNA strand’s rotational and positional conformation, and demonstrated that a graphene membrane with quantum point contact geometry exhibits greater electrical sensitivity than on with so-called uniform armchair geometry. The team has proposed a graphene-based field-effect transistor-like device for DNA sensing. “One of the major challenges in computing GNR sensitivity to external charges arises from the latter’s different natures and origins,” Leburton points out. “Specifically, these are the static charge in the dielectric materials supporting, or sandwiching, the GNR, and – most importantly – the dynamical ionic charge in the electrolyte containing the DNA, which is in liquid phase.” To address this, the researchers used a multi-scale technique, where the GNR and DNA are simulated atomistically (with a tight-binding technique and molecular dynamics, respectively) while the electrolyte and dielectric are treated as continuum media. “The former is simulated as an intrinsic semiconductor with large dielectric constant and a pseudo-band gap in the presence of a self-consistent potential, and the dielectric charge is modeled by assuming a static fix distribution,” Leburton adds. “The induced potential variations on the GNR and nanopore edges are obtained self-consistently by solving the Poisson equation, and fed into the NEGF code to compute the resulting conductance variation in the GNR.”last_img read more

Astronomers observe unusual outburst activity of binary star AG Draconis

first_img Located in a spherical halo around the Milky Way, AG Draconis (AG Dra for short) is a classical symbiotic variable binary of type S. The system consists of a cool red giant with an effective temperature of about 4,300 K and a hot white dwarf with a high temperature of at least 100,000 K. The red giant is about 30 times larger than our sun, however, it has a mass of only 1.5 solar masses. The system’s white dwarf is about 40 to 60 percent less massive than the sun. The stars fully orbit each other approximately every 550 days.AG Dra is one of the most studied symbiotic star systems as its variations in brightness have been observed by astronomers for more than a century. The binary experiences a characteristic symbiotic activity with the alternation of active and quiescent stages. Its apparent magnitude of around 9.8 is known to increase by up to 1.4 when outbursts occur during active stages that take place at intervals of nine to fifteen years.Previous observations of AG Dra have shown that these active stages consist of several outbursts repeating at about a one-year interval. The observed periods of activity start with a major outburst that is usually cool as the expanding pseudo-atmosphere of the white dwarf cools down. However, the latest phase of activity, which started with an outburst in 2015, appears to be different from previous ones.A team of astronomers led by Jaroslav Merc of the Pavol Jozef Šafárik University in Košice, Slovakia, has analyzed the recent activity of AG Dra using data from the Astronomical Ring for Access to Spectroscopy (ARAS) database. They found that the brightness of AG Dra started to increase in the first half of 2015, with a weak pre-outburst. The second and more prominent outburst occurred in April 2016.The study revealed that in May 2015 the brightness of AG Dra began to rise, achieving 10.7 mag in B and 9.6 mag in the V filter. The researchers described the event as a less prominent, minor outburst. During the second outburst that took place in April 2016, the binary reached maximum brightness of 9.9 and 9.1 mag in the B and V filters, respectively. Given that both brightenings were classified as minor (hot) outbursts, the recent period of activity of AG Dra seems unusual when compared to previous ones.”According to the photometric behavior, both brightenings belong to the minor outbursts of AG Dra. Such photometric behavior of the active stage is very untypical because more often, the activity of AG Dra starts with the major outburst,” the paper reads.The astronomers noted that active periods of AG Dra usually commence with major outbursts when the brightness reaches 8.8 and 8.4 mag in the B and V filters, respectively. The newly observed unusual activity raises questions about the nature of these outbursts. The authors assume that the events could belong to a new type of outbursts or they could indicate some transition between the hot and cool outbursts.

New ultraluminous Xray pulsar discovered

first_imgUsing ESA’s XMM-Newton and NASA’s NuSTAR space telescopes, a team of astronomers from Germany has detected a new ultra-luminous pulsar in the galaxy NGC 300. The finding of this pulsar, which received designation NGC 300 ULX1, is detailed in a paper published November 9 on the arXiv pre-print repository. Explore further More information: Chandreyee Maitra et al.

The red circles denote the source extraction region used for the analysis. Credit: Maitra et al., 2018. Ultra-luminous X-ray sources (ULXs) are point sources in the sky that are so bright in X-rays that each emits more radiation than 1 million suns emit at all wavelengths. Although they are less luminous than active galactic nuclei, they are more consistently luminous than any known stellar process. Astronomers generally believe that due to their brightness, most ULXs are black holes. However, recent observations have found that some ULXs showcase coherent pulsations. These sources, known as ultra-luminous X-ray pulsars (ULXPs), are neutron stars typically less massive than black holes. The list of known ULPs is still relatively short, hence detecting new objects of this class is essential for researchers studying the universe in X-rays.Now, a group of astronomers from Max Planck Institute for extraterrestrial Physics in Garching, Germany, led by Chandreyee Maitra, reports the detection of pulsations from the source NGC 300 ULX1, located in the spiral galaxy NGC 300, some six million light years away from the Earth. Discovered in 2010, NGC 300 ULX1 was initially classified as a supernova, but later re-classified as a possible high mass X-ray binary.By analyzing data from simultaneous observations of NGC 300 ULX1, performed in December 2016 using X-ray Multi-Mirror Newton (XMM-Newton) and Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft, Maitra’s team identified pulsations from this source.”Pulsations from NGC 300 ULX1 were discovered during simultaneous XMM-Newton/NuSTAR observations in Dec. 2016,” the researchers wrote in the paper.According to the study, NGC 300 ULX1 had a spin period of about 31.71 seconds at the start of NuSTAR observations, which decreased linearly within a few days to approximately 31.54 seconds at the end of the XMM-Newton/NuSTAR observing campaign. The observations also found that the pulsar has a spin-up rate of 556 ns/s and a broadband unabsorbed luminosity of 4.7 duodecillion erg/s.Furthermore, the astronomers checked archival data from observations of NGC 300 ULX1 using NASA’s Swift space telescope and Neutron star Interior Composition Explorer (NICER) on the International Space Station. These data show that the spin period of this pulsar decreased exponentially from about 45 to 17.5 seconds during a timespan of 2.3 years.The researchers noted that NGC 300 ULX1 is the fourth ULXP known to date, and exhibits an extreme spin-up rate, as well as a relatively constant luminosity over a long span of time. They added that its spin-up rate is one of the highest ever observed from an accreting neutron star.In concluding remarks, the authors of the paper underlined that due to its properties, NGC 300 ULX1 could provide a rare opportunity for astronomers to study spin evolution of accreting neutron stars at extreme accretion rates. The pulsar could also help us better understand the similarities between ULXPs and supergiant high mass X-ray binaries.

Cinema is cinema. Before criticizing one must understand what goes into the making of a film,” highlights Dr Sharma, who attended the course twice in 2009 and 2014. Also Read – Leslie doing new comedy special with Netflix At FAC one gets to live with films for a month. One gets to witness such archives and real footages which are not easily available. Watching a film on reel with that sound and feel is a rare treasure in the digital era. National Museum Institute (NMI) organises Art Appreciation Course and Bhartiya Kalanidhi (Hindi medium – covers Indian art) consisting of 20 illustrated lectures encouraging students to know and appreciate Indian and global art. “We as citizens are unaware of our own cultural heritage. This course not only enlightened me but also made me proud of our country’s art and culture. To know those roots, this course is a must,” explains Dr Sulekha Bhargava, freelancer contributing to art and craft, a participant of Art Appreciation in 2001 and 2002. This course not just puts light on the importance of symbols, different sculptors, personalised paintings but also on the archaeological aspect of it.  “From lectures to artefacts and visiting museums, it not only develops a visual understanding but also creates an everlasting impact. No other course witnesses people from different walks of life coming together to cherish what we have,” comments Dr Bhargava. National School of Drama (NSD) conducts Theatre Appreciation Course(TAC) that aims to enable the understanding and appreciation of theatre as an art form in India and the world. “My experience at the Theatre Appreciation Course was incredible. The 9 day course in NSD was well designed and covered a huge array of specialized discipline in theatre itself- compositional techniques in music, importance of Natyashastra, Theatre Scenography, costumes, Women and Puppetry Theatre, Proscenium Theatre etc.,” shared Anjana Ghosal, performing artist/ vocalist who was a participant of TAC-NSD 2016.

It helped me to critique and analyse a theatre production intelligently,” Ghosal added.During a week long course at NSD one gets to interact with renowned theatre practitioners and have discussions. They also get the opportunity to watch the treasured archives along with watching and analysing live plays. “TAC at NSD helped me to understand the difference between theatre acting and acting for cinema. Earlier, while watching a play, I never noticed much of its elements. But now, every play I watch compels me to critically analyze and appreciate the creative work,” says Bishwajeet Mookherjee, a budding filmmaker who believes that the course is for someone who wishes to understand the art of theatre and not for someone who wishes to learn acting. For a better understanding of a subject, one must be acquainted with the history of the subject, its evolution and the basics or nuances of various forms. Notifications for admission to these courses are advertised every year on their official websites, newspapers and social media. One can keep a track between the months of April and June.last_img read more

Wedding fashion for men

first_imgIn the wedding season, it’s not just women who want to look their best, but men too like to look dapper. Men can ditch the jutti as footwear and instead opt for the European-style like brogues, suggest experts. 4Embroidery and prints: The 2017/18 wedding season isn’t that much about the fabrics as much as bold textures. Textures are making exceptional style statements. Heavy embroidery is in and so are loud prints. The floral designs are back this season. The pink floral sherwanis to heavy gold floral bandhgalas are the taste of this season. Also Read – Add new books to your shelf4Sherwanis: A short kurta with a Patiala salwar or a dhoti that is loose at the thigh and tapers at the calves, is ideal attire for wedding functions. When going with classic churidar, mocassins and brogues work wonders to the outfit.4Footwear: The juttis are out; fashion leather European footwear is in. Move over the traditional black jutti, and make way for the European style statement. It wouldn’t be wrong to say that this is where the “fusion” starts. Also Read – Over 2 hours screen time daily will make your kids impulsiveMen are preferring the burnish brogues, the croc-leather textures and the hybrid combo footwear to add that class and style to the generally traditional outfit.4Bandhgala Jacket: An embroidered bandhgala jacket looks exquisite and offers a number of styles. A bandhgala jacket opens the door to experiments. Team it up with a classic black kurta and accessorise it with jewels, cuff-pins or a stone studded brooch.4Accesorise it: Today, there are number of accessories options that are available for men.

The angarakha and bandhgalas are being enlightened with the glitter from men’s jewellery – be it subtle chains or heavy pearls.4Play with shades: Gone are the days when only golden was considered as a customary colour code for weddings. A pop of red, green or a vibrant blue is what you need to incorporate in your styling. The colours are indeed festive and will take away the gloomy blues from your mood.But one should always take care of not exploding colours in the outfit. Balancing is very important when playing with shades.Don’t shy away from colours like blue, purple and pink though the gold, black and white are still the ultimate kings.The bandhgalas, angarakhas and sherwanis are being worn with beautiful stoles spreading from shoulder to the end of the right arm in the traditional way. These stoles are heavily embroidered and generally velvet or high-weave cotton blended in wood.4Mix it up: The 2017/18 season has seen lots of fusion – bandhagalas with slim-cut trousers with European footwear and royal accessories.last_img read more

Nuts keep diabetics heart healthy

first_imgEating a handful of nuts daily, particularly tree nuts, may reduce the risk of cardiovascular disease among people with Type-2 diabetes, associated with an increased risk for high cholesterol, heart disease and stroke, say researchers, including one of Indian origin. Tree nuts such as walnuts, almonds, Brazil nuts, pistachios, pecans, macadamias, hazelnuts and pine nuts were strongly associated with reduced risk of coronary events, cardiac death and total mortality compared with peanuts. Also Read – Add new books to your shelfThe results showed that eating even a small amount of nuts had an effect. While the exact biological mechanisms of nuts on heart health are unclear, researchers noted that nuts appear to improve blood sugar control, blood pressure, metabolism of fats, inflammation and blood vessel wall function. “Cardiovascular disease is the leading cause of death and a major cause of heart attacks, strokes and disability for people living with Type-2 diabetes,” said Prakash Deedwania, Professor at the University of California-San Francisco. Also Read – Over 2 hours screen time daily will make your kids impulsive”Efforts to understand the link between the two conditions are important to prevent cardiovascular complications of Type-2 diabetes and help people make informed choices about their health,” Deedwania added. In this study, reported in the Circulation Research journal, the team used data from 16,217 men and women before and after they were diagnosed with Type-2 diabetes. People who increased their intake of nuts after being diagnosed with diabetes had an 11 per cent lower risk of cardiovascular disease, a 15 per cent lower risk of coronary heart disease, a 25 per cent lower risk of cardiovascular disease death, and a 27 per cent lower risk of all-cause premature death. Each additional serving per week of total nuts was associated with a three per cent lower risk of heart disease and six per cent lower risk of heart disease death. Adding more nuts to one’s diets proved beneficial probably at any age or stage. “It seems never too late to improve diet and lifestyle after diagnosis among individuals with Type-2 diabetes,” the researchers said.last_img read more
