IEEE Specturm reports on how the robot works:The result is this little device. It’s simple motor turns an unbalanced mass at a uniform velocity. As the mass swings around, it causes the robot to bounce back and forth between the tube walls. Two rubber o-rings let the researches specify the exact contact points and increase friction with the walls. Instead of using bristles or fibers, and vibration that moves the robot in a low-friction direction, the o-rings provide a little more control for the robot’s operators. And, the design employed by Carnegie Mellon also overcomes another design flaw common to tube climbing robots of the past: Difficulty getting out of the tube. Because of the way robots designed with bristles and fibers use the lowest-friction direction to climb the tube, operators have to work against maximum friction to remove the bot. With the o-ring design, this is no longer an issue.In addition to easier removal, the Carnegie Mellon bot also features a payload capacity of five times its weight. Depending on the size of the tube, this robot can move up to 20 body-lengths per second. The versatility of this robot could lead to a number of different applications, especially for those that require that quick navigation of 3D tubes.

Researchers drill historic hole in atlantic ocean floorcenter_img © 2010 PhysOrg.com The Earth’s mantle is the part of the planet that lies between the crust and the iron ball at its center, and to reach it, would require drilling down from a position in the ocean, because the crust is much thinner there. Even still, it would mean drilling through five miles of solid rock. And if that doesn’t sound hard enough, temperatures increase the farther down you go, and could reach as high as 1,050 degrees Fahrenheit; high enough to render useless most modern drill bits. Last but not least is the problem of atmospheric pressure, which increases the deeper you go, to somewhere in the neighborhood of 4 million pounds per square foot near the mantle. That last one may not seem like much of a problem, but with exploratory drilling, it becomes a problem rather quickly when you remember that it’s not just a hole they plan to dig, but a hole that can be used to extract samples from very far below.To retrieve a sample, the drillers would have to rely on drills without a riser (drills that use double pipes for venting gases) which would mean pumping seawater down into the hole through the drill pipe with sufficient pressure to force whatever is being dug back up to the surface so that it can be examined.This would not be the first time that a sample of the mantle would be recovered however, as volcanoes and such have been forcing under-crust material to the surface for eons; it would be the first time that a sample was found though that hasn’t been tainted by the process that brought it up to us, and that scientists say, is worth whatever the cost might add up to over time as the project carries on through years of laborious drilling.The pair plan to begin searching for a suitable site somewhere in the Pacific this spring, but don’t expect the technology, nor the funding to allow them to start drilling till perhaps 2018.

The Showa Hanako 2 actually goes much farther lengths to create a realistic experience for the training practitioner. The robots mouth is designed to be as realistic as possible, down to the way that it feels. The creators of this dental bot got help from an unusual source in order to create that realism. Orient Industry, a company that is recognized as one of Japans top makers of sex dolls, was consulted to help the research team make up realistic skin, tongue and mouth areas. The system is also equipped with a basic program for voice recognition; this allows the training dentist to carry out some basic conversation with the robot during the exam or procedure. Like any good patient Hanako can give the dentist feedback about his or her performance. Unlike most patients however, she can store and analyze the student’s performance, giving then a detailed amount of experience on the computer. The robot will be on sale in Japan later this year. No details about pricing have been released at this time. Explore further (PhysOrg.com) — Going to the dentist is something that we all have to do. Going to a novice dentist, and his or her drill, is something that most of us would rather avoid but they have to practice somewhere.

first_img(Phys.org) — Yet another ATM card-reading heist technique to worry about: Thieves have evolved their ATM techniques in coming up with skinny skimmers to work inside the ATM that are so small they can be fitted inside the credit card insertion slot. They record the data stored on the magnetic stripe on the back of the card as it is slid into a compromised ATM. The skimmers when equipped with a secondary component also record ATM customers entering their PINs, such as with a PIN pad overlay or hidden camera. The news was revealed, as police in an unidentified European nation retrieved the wafer-thin skimmers. Windows XP ATM’s Under Hacker Attacks in Europe – US Could Be Next! The European ATM Security Team (EAST), an organization that collects ATM fraud reports, has been publishing their ATM fraud alerts, They have been issuing country crime updates from representatives of countries in the Single Euro Payments Area (SEPA), and from non-SEPA countries. They say a number of European countries are noticing higher-quality and more efficient skimming devices.According to EAST, one country which they have not named, alerted them about a new form of skimming device that is thin enough to be inserted directly into the card reader slot. These devices record the data stored on the magnetic stripe on the back of the card as it is slid into the compromised ATM. EAST notes that these insert-skimmers are continuing to evolve whereby a secondary component to record customers entering their PINs, such as a PIN pad overlay or hidden camera, is being used.EAST was alerted to the new skimmer by one of its reporting countries; the U.S. is no stranger to the fact that techniques in ATM card-reading crimes are always evolving. According to the FBI, ATM skimming is a growing criminal activity that some experts believe costs U.S. banks hundreds of millions of dollars annually. ATM card skimming is defined as a method used by criminals to capture data from the magnetic stripe on the back of an ATM card. The devices used are small enough to escape notice by most ATM customers. What is unique about the new skimmers is that they are inserted into the slot where other types reported have been fastened in close proximity to a card reader. Pin capturing refers to a method of attaching cameras and other imaging devices to ATMs to catch the victim’s PIN. Interestingly, the FBI says that ATMs are not the only target of skimmers. The agency has also seen them at gas pumps and other point-of-sale locations where customers swipe cards and enter PINs. © 2012 Phys.org More information: www.european-atm-security.eu/W … tion=fullnews&id=110center_img Explore further Citation: Security team sees evolution of skinny slot-fitting ATM skimmers (2012, July 25) retrieved 18 August 2019 from https://phys.org/news/2012-07-team-evolution-skinny-slot-fitting-atm.html This document is subject to copyright.

first_img NIST System Sets Speed Record For Generation of Quantum Keys for ‘Unbreakable’ Encryption (Phys.org)—A team of German physicists has successfully demonstrated an ability to perform quantum key distribution (QKD) exchange between an airplane in flight and a ground station, paving the way perhaps to the same kinds of communications between satellites and ground stations which could lead to a global quantum based secure communications network. The team presented their results at the QCrypt convention this past week. Explore further Optical ground station. a Telescope of the optical ground station located on the roof of the DLR institute building next to the airport Oberpfa enhofen. b Closeup of the optical breadboard attached to the back of the main telescope mirror indicating the signal path for the qubits (green) and the beacon light (red). Credit: Sebastian Nauerth et al. Two make such a system work, the photons must be sent from one station and received by another. In this case, they were sent from a moving airplane using a laser and mirrors to a ground station that also used mirrors, no easy feat due to the sensitivity of attempting to read individual photons. Still the researchers managed to make it happen and perhaps even more remarkably, were able to hold on to the connection for ten minutes; long enough to transmit 10 kilobytes of data (at 145 qubits per second) with an error rate of just 4.8%. That’s enough to send a key, and that’s all that’s really needed to build quantum based network.Based on these results alone, it’s clear that a truly secure network could be put in place, in a battle zone for instance, with keys being transmitted from drones hovering overhead. But of course, that won’t be enough, the real goal will be to see if the same feat can be achieved between satellites and ground stations giving us a world where all communications can be made almost perfectly secure. Scientists have over the years developed some very powerful encryption schemes that are almost impossible to crack, yet virtually all of them rely on one weak point, the key that is used to unlock them. For this reason, cryptologists have been pinning their hopes on QKD. This is because of the nature of quantum bits; looking at or measuring them causes them to be changed, which would alert the true owners of the key that a breach has occurred.QKD is where encryption keys are generated based on the polarization of photons to represent 1s and 0s. The photons in such a system are converted to qubits on the receiving end where they can be read and interpreted. While the idea has been around for quite some time, it’s only recently that workable devices have actually been built. Prior to this new development, another team had achieved a QKD exchange between two stationary buildings. © 2012 Phys.org More information: Paper PDF: www.qcrypt.net/docs/extended-a … 12_submission_12.pdf The Do228 aircraft equipped with the ight terminal.

The new entry is defined in a promotional video (with symphonic, celestial music and a British voiceover for gravitas) as the world’s first cloud computer. The product combines a hardware controller integrated with software for an all in one storage, compute, and networked services system. To hear Nebula’s team describe it, the Nebula One is a product that can reinvent cloud computing. Explore further The fundamental selling point of Nebula One is that it will make private clouds easier to operate. The goal underlying development of the new product has been to make a private cloud system something that the business user can plug in and turn on, achieving, at log-in, an availability of computing resources on demand. “Previous cloud solutions often required users to put in hours of work to provision and maintain their computing environment. The Nebula One private cloud system frees the organization to focus on applications instead of infrastructure,” according to Nebula’s team.center_img The controller itself is on sale now, at a starting price of $100,000, which may run higher, depending on the customer’s needs and configurations. The new Nebula One system must be coupled with certified industry-standard x86 servers. Customers can choose on their own which vendor’s certified servers, such as from Dell, or HP, that they want to include as part of the system. The Nebula One controller can do all the pooling of resources from up to 20 server nodes, so that it can deliver its business customer a unified cloud system. NASA’s Nebula Cloud Computing Technology To Play Key Role In New Open Source Initiative Nebula One’s software could configure extra servers if and when they are added. A single-rack deployment is enough for most medium-sized businesses, but the Nebula One system can scale to multi-rack deployments for large enterprises.Chris Kemp, co-founder and CEO of Nebula, who had served in CTO and CIO posts at NASA, along with his team, worked on their product with the intent of providing a cloud computer solution that can allow a business to go “self-service” in operating a private cloud infrastructure. The Nebula One solution runs Cosmos, Nebula’s distributed enterprise cloud operating system. which builds on OpenStack, according to the company’s press release, providing compatibility with Amazon Web Services and OpenStack APIs.(OpenStack, founded by Rackspace Hosting and NASA, is defined as a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, managed through a dashboard, that gives administrators control while empowering users to provision resources through a web interface.

first_img Citation: New two-dimensional ‘borophene’ sheet (2016, April 19) retrieved 18 August 2019 from https://phys.org/news/2016-04-two-dimensional-borophene-sheet.html Researchers from the Institute of Physics at the Chinese Academy of Sciences and the Collaborative Innovation Center of Quantum Matter in China have identified two new types of boron sheets that they grew on an Ag(111) surface. The sheets are stable, relatively inert to oxidation, and bind loosely to the silver substrate, making these “borophene” sheets excellent candidates for further research into boron-based electronic devices. This work appears in Nature Chemistry.Using molecular beam epitaxy to deposit boron onto a silver substrate, Baojie Feng, Jin Zhang, Qing Zhong, Wenbin Li, Shuai Li, Hui Li, Peng Cheng, Sheng Meng, Lan Chen, and Kehui Wu report the formation of two structurally different boron sheets. Both are comprised of a triangular boron lattice, but the hexagonal holes are arranged differently in the two sheets. These sheets follow theoretical predictions that B36 units should have a triangle lattice with a hexagonal hole in the center.The boron sheets were grown on a single-crystal of Ag(111) in high vacuum using direct evaporation of pure boron. Scanning tunneling microscopy studies revealed two different phases that were observed as temperature increased. The first phase, labeled S1, was observed at temperatures above 570K and corresponds to theoretical β12 sheets. The second phase, labeled S2, was observed at temperatures above 650K and corresponds to theoretical χ3 sheets. At higher temperatures, most of the S1 phase converts to S2. Both appear as monolayer islands of parallel boronphene stripes with parallel rows or protrusions.Electron charge analysis confirms the locations of boron atoms on the silver surface and boron atomic density studies provided further evidence for the formation of β12 and χ3 sheets. The atomic density for the S1 phase was found to be 33.6 +/- 2.0 nm-2, which is very close to theoretical β12 value of 34.48nm-2. The boron density did not change for the S2 phase indicative of the χ3 structure, which has a predicted atomic density of 31.3nm-2.Using XPS studies, Feng, et al. found that the boron sheets are relatively stable, particularly within the borophene islands. The edges of the islands tended to oxidize, while the center remained relatively unchanged. This remained the case even after subjecting the sheets to high concentrations of oxygen gas.β12 and χ3 sheets were not necessarily the lowest energy borophene sheets that the models had predicted. In an effort to understand why these structures were observed over the predicted energetically minimum state, Feng, et al. conducted energy formation studies and found that interaction with the silver surface makes formation of the β12 and χ3 sheets thermodynamically favorable. However, even though the silver surface is important for the formation of the sheets, the interaction between the boron sheet and the Ag(111) surface is not very strong. Several factors, including adhesion energy calculations, the distance between the boron sheet and the substrate, and the small charge transfer between the substrate and boron sheet, indicate that the boron sheets are predominantly bound to the surface via the edges. This means that the borophene sheets could be separated from the silver surface, similar to graphene. Several recent publications have spurned greater interest in these borophene sheets. Theoretical work by researchers from Rice University in Houston and researchers from Ningbo University in China supports the structural models proposed in this research paper, and suggest that these two borophene sheets are likely to be superconducting at temperatures around 10K. These sheets in this study are relatively stable and loosely bound to the silver surface, properties that make them good candidates for eventual practical use for boron-based electronic devices. Explore further (Phys.org)—Boron, the neighboring element to carbon on the periodic table, has chemical features that make it an enticing candidate for two-dimensional, conductive, atomically homogenous substrates similar to graphene. Three-dimensional bulk boron is non-metallic and is used in semiconductor chemistry. However, theoretical studies and prior work in trying to isolate two-dimensional boron show that two-dimensional boron should have metallic properties. To date, only one two-dimensional boron allotrope has been identified. For 2-D boron, it’s all about that base (a,d) are large scale STM images showing the monolayer borophene islands on Ag(111) substrate. (b,e) are the corresponding high resolution STM images,(c,f) are the atomic structure models, corresponding to triangular boron lattices with periodic arrangement of boron vacancies.

More information: Baojie Feng et al. Experimental realization of two-dimensional boron sheets, Nature Chemistry (2016). DOI: 10.1038/nchem.2491AbstractA variety of two-dimensional materials have been reported in recent years, yet single-element systems such as graphene and black phosphorus have remained rare. Boron analogues have been predicted, as boron atoms possess a short covalent radius and the flexibility to adopt sp2 hybridization, features that favour the formation of two-dimensional allotropes, and one example of such a borophene material has been reported recently. Here, we present a parallel experimental work showing that two-dimensional boron sheets can be grown epitaxially on a Ag(111) substrate. Two types of boron sheet, a β12 sheet and a χ3 sheet, both exhibiting a triangular lattice but with different arrangements of periodic holes, are observed by scanning tunnelling microscopy. Density functional theory simulations agree well with experiments, and indicate that both sheets are planar without obvious vertical undulations. The boron sheets are quite inert to oxidization and interact only weakly with their substrate. We envisage that such boron sheets may find applications in electronic devices in the future. © 2016 Phys.orglast_img read more

first_imgKolkata: The West Bengal Khadi & Village Industries Board (WBKVIB) has geared up to make muslin more popular and attractive among people. “Our weavers are now successfully using Jacquard machines for doing intricate designs on cotton sarees, which is a very difficult process. Cotton sarees with designs are very much in demand, particularly among the celebrities. So, we are hopeful that with the production of more and more such sarees, the demand will grow,” a senior official of WBKVIB said. Also Read – Heavy rain hits traffic, flights”Till now, Jacquard machines have only been used for designs on silk sarees and we have found that such designer sarees have been selling like hot cakes in the outlets,” he added.The Jacquard machine is a device fitted to a power loom that simplifies the process of manufacturing textiles with complex patterns like brocade, damask and matelassé. The loom is controlled by a “chain of cards”, a number of punched cards laced together into a continuous sequence. Multiple rows of holes are punched on each card, with one complete card corresponding to one row of the design.

People, particularly foreigners, love to watch the entire process of production on their own and then go for buying,” said Mrityunjoy Bandyopadhyay, CEO of WBKVIB. It may be mentioned that in July 2015, the state MSME department had started Project Muslin for the revival and rejuvenation of brand Khadi and wooing back some of the traditionally skilled artisans, who had left the handloom sector and sought employment in less-skilled sectors.In Bengal, there are primarily seven districts which can be identified as major pockets of muslin fabric, namely Murshidabad, Birbhum, Nadia, Burdwan, Malda, Hooghly and Paschim Medinipur. There are around 900 to 1,100 families engaged in muslin production. More importantly, even though muslin is produced in some countries of West Asia, their artisans can hardly go beyond the 200 count. It is only these six districts where yarns of 500 count and more are produced. Such fine yarns are of high demand in the international market, especially in Japan.last_img read more

first_imgWhen it comes to better memory skills, the fairer sex seems to score more than men, researchers have found.However, the memory of women tends to fade as the oestrogen – female sex hormones – levels decline or as women enter the post-menopause phase.Memory loss is a well-documented consequence of the ageing process. In a study published online in the journal Menopause, the findings showed that as women enter the menopause transition period, they develop increased forgetfulness and “brain fog”.  Also Read – Add new books to your shelfFurther, women are also disproportionately at risk for memory impairment and dementia when compared with men. In addition, declines in oestrogen levels in postmenopausal women were found to be specifically associated with lower rates of initial learning and retrieval of previously recalled information, while memory storage and consolidation were maintained. Despite these conditions working against them, middle-aged women still outscore their similarly aged male counterparts on all memory measures, the researchers said.  Also Read – Over 2 hours screen time daily will make your kids impulsive“Brain fog and complaints of memory issues should be taken seriously, as these complaints are associated with memory deficits,” said Jonn Pinkerton, Executive Director at The North American Menopause Society (NAMS) – a US based non-profit organisation. For the study, the team included 212 men and women aged 45 to 55 years and assessed their episodic memory, executive function, semantic processing, and estimated verbal intelligence through cognitive testing.last_img read more

first_imgDarjeeling: The autopsy of the rhinoceros, whose carcass was recovered from Gorumara National Forest has revealed the death could have been caused by poison. Three persons have been detained from a forest village for questioning.Incidentally on December 25, the carcass of an adult rhinoceros was recovered from Gorumara National Forest in the Jalpaiguri district. The horn of the rhino was hacked off giving rise to the doubt that the animal was killed by poachers. Also Read – Rain batters Kolkata, cripples normal lifeNo bullet was found in the body after a four hour long autopsy. The Forest department feels that poison could have been administered to kill the rhino. In order to find out the nature of the poison that could have been administered, body parts including tissues of the rhino are being sent to a forensic lab. Many theories are afloat regarding the poison theory. As chances of poisoning a rhino by giving it fodder laced with poison is bleak, foresters feel that Aconitum could have been used. Poachers from North East have mastered the art of killing animals like rhinos and elephants by using this poison. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIn the past, there are records of elephants being killed by poachers from North East using Aconitum in Buxa Tiger Reserve. In 2016, after a rhino was killed in Jaldapara National Forest, a syringe containing Aconitum was recovered from near the carcass. A high alert has been issued in Jaldapara National Forest. Incidentally in 2016, around three rhinos were killed in Jaldapara. Police arrested three persons in connection with the incident and an AK47 rifle used for shooting rhinos was recovered.”The rhino carcass was recovered from an area called Garati at Gorumara. Garati is such an area where a sound of a shot cannot be avoided from reaching people. Hence, we feel the rhino was not shot using a firearm. A metal detector was also used during autopsy but no bullet could be located inside the body. We feel a lethal poison could have been used. Further forensic examination will help pinpoint the cause of death,” stated Ujjwal Ghosh, Chief Conservator of Forest, Wildlife North. Incidentally on April 21, 2017, the decomposed carcasses of two rhinos was found in the same locality. The horns of the rhinos were sawed off.last_img read more
