first_img Hitachi in collaboration with NTT Communications and Tokyo University of Science have come up security solutions that will protect citizens from unwarranted intrusion of their personal and financial data, according to Digital World Tokyo. The fact that world-wide governments collect gargantuan amounts of data on citizens is not a surprise to anyone. Whether it is birth certificates, drivers licenses, unemployment insurance, social security and a host of other events, there is a record. Governments have done several things to both create and solve the problem with mixed results. Primarily the two solution/problems are; “contracting out” and attempts to digitize the gargantuan amount of data. The BBC reports that a series of “gone missing” CDs developed and promulgated by UK governmental agencies. Specifically, a contractor of the Drivers Standards Agency was given personal data on a CD listing the names of individuals who took their driving theory test from 2004-2007. The CD was sent to another private contractor in the United States for analysis and somewhere in the process, the CD with millions of UK citizens data went missing. In the recent past, the United States had similar incidences of compromised personal data by the Veterans Administration. According to Digital World Tokyo, NTT Communications has developed a technique for distributing data to three different locations for safe storage with more efficiency. The NTT improvement allows the data to be sent in a compressed mode that reduces the size by one-third. Thus, allowing the data to be sent simultaneously to the three locations. Hitachi’s contribution to the project involves applying different levels of encryption to the various levels of secure data. Data concerning financial and sensitive personal data is hidden by layers of encryption. The University of Tokyo in collaboration with Hitachi has developed another means to bring security to every day life. This technology would enable cell phones to apply advanced encryption techniques that heretofore were reserved for high-end mega computer systems. The technology can be applied to any form of communication. Whether it is financial data, video or compilations of data. It appears the East anticipated the common sense need for secured data collection and spent the last three years developing a solution. As of this writing, the Japanese have not solved the problem of errant contractors or cavalier governmental agencies.Copyright 2007 Mary Anne Simpson & Citation: Gone Missing CDs: Personal & Financial Data Solutions (2007, December 19) retrieved 18 August 2019 from The collaborative efforts of Hitachi, NTT and Tokyo University have come up with means to protect secure data stored on CDs.

first_img Scientists take next step towards observing quantum physics in real life In the emerging field of cavity optomechanics, physicists may have the opportunity to investigate the boundary between quantum and classical systems. Optomechanical systems are mechanical systems that can be manipulated by light – for example, a thin membrane being vibrated by light in an optical cavity. Two recent studies have proposed that, with current technology, it should be possible to cool down two of these millimeter-scale membranes in such a way that they act like a single molecule. No matter how far apart they are, the membranes could be interrelated through quantum entanglement, so that measuring one membrane instantly affects the other.In a study published in Physical Review A last October, physicists Mishkat Bhattacharya and Pierre Meystre from the University of Arizona in Tucson took the first steps toward showing how a pair of vibrating membranes can form a molecule-like state. By interacting with photons from a laser, the membranes become coupled together. According to the scientists’ calculations, this results in a state with two different modes with different resonant frequencies: in one mode, the membranes move together, while in the other mode, the membranes move opposite to each other. By shining a particular laser frequency on the membranes, it should be possible to cool down each mode’s vibrations separately. Since these vibrational states are analogous to the excitations of a single molecule, the experiment demonstrates how the two membranes act as a single system. In a second study published in Physical Review Letters last November, Michael Hartmann and Martin Plenio of Imperial College London proposed a similar experiment, with the additional step of entangling the two membranes. The researchers calculated that, by using certain laser frequencies to cool the modes, the interactions between them could entangle the membranes for as long as the lasers remain on. Two weak lasers could then verify the entanglement without destroying it.Experimentally demonstrating this membrane entanglement will require precise and challenging methods, but the results could enable physicists to investigate the transition from the quantum to classical world.More information: M.

While such quantum properties have been widely observed for electrons and molecules, recent experiments have shown that larger objects may also demonstrate quantum effects.

What if you didn’t have to touch the screen? A group from University of Alberta, Toronto, and Autodesk Research presented their answer at the ACM Symposium that took place from Oct. 7-12 in Cambridge, Mass. Their Magic Finger is a thimble-like device worn on the user’s finger and allows the user’s gestures to control smart devices like phones or tablets. “If I am walking down the street and the cellphone is in my pocket, I can make a swiping gesture and execute a function like making a call,” Tovi Grossman, a scientist at Autodesk Research, told Discovery. Magic Finger is placed on the fingertip using an adjustable Velcro ring. As a demo video shows, commands can be placed on a variety of surfaces for content to be displayed on the screen.

Sharp Releases Notebook PC with Optical Sensor LCD Pad Explore furthercenter_img Interestingly, the Magic Finger can differentiate its input to a device according to the surface with which the device is interacting: wood or cloth. “While texture has been previously explored as an output channel for touch input we are unaware of work where texture is used as an input channel,” the authors said in their paper, “Magic Finger: Always-Available Input through Finger Instrumentation.”The researchers worked on Magic Finger as a proof-of-concept prototype that enables input through finger instrumentation. And they emphasize that this “instrumentation” is what makes the Magic Finger unique. “We propose finger instrumentation, where we invert the relationship between finger and sensing surface: with Magic Finger, we instrument the user’s finger itself, rather than the surface it is touching.” Tests of the device’s accuracy are encouraging: Results show that Magic Finger is able to recognize 22 environmental textures or 10 artificial textures with an accuracy of above 99 percent. Overall, their evaluation showed that Magic Finger can recognize 32 different textures with an accuracy of 98.9 percent, allowing for contextual input. “Accuracy levels indicate that Magic Finger would be able to distinguish a large number of both environmental and artificial textures, and consistently recognize Data Matrix codes,” they said.They also recognized the study’s limitations: Their hardware was tethered to a nearby host PC. “This simplified our implementations, but for Magic Finger to become a completely standalone device, power and communication needs to be considered.” The interactions that they demonstrated should be treated as “exploratory,” they added. Magic Finger is a research project from Autodesk Research, in collaboration with the University of Toronto. Xing-Dong Yang, Tovi Grossman, Daniel Wigdor and George Fitzmaurice authored the paper presented at the ACM UIST 2012 conference proceedings. A small plastic casing holds the components. There is a small micro camera and optical flow sensor attached to the finger. Magic Finger senses touch through the optical sensor, enabling any surface to act as a touch screen.For the optical flow sensor, an ADNS 2620 optical flow sensor with a modified HDNS-2100 lens. Used in optical mice, the sensor is reliable on a variety of surfaces. The sensor detects motion by examining the optical flow of the surface on which it is moving. For an enhanced scope, they used an AWAIBA NanEye micro RGB camera embedded on the edge of the optical flow sensor. Magic Finger senses texture through the micro RGB camera, allowing actions to be carried out based on the surface being touched.

first_imgThe replicating entities. Credit: (c) Junghoon Kim et al. Nature Nanotechnology, doi:10.1038/nnano.2015.87 © 2015 More information: “Self-replication of DNA rings” Nature Nanotechnology, DOI: 10.1038/nnano.2015.87AbstractBiology provides numerous examples of self-replicating machines, but artificially engineering such complex systems remains a formidable challenge. In particular, although simple artificial self-replicating systems including wooden blocks, magnetic systems, modular robots and synthetic molecular systems have been devised, such kinematic self-replicators are rare compared with examples of theoretical cellular self-replication. One of the principal reasons for this is the amount of complexity that arises when you try to incorporate self-replication into a physical medium. In this regard, DNA is a prime candidate material for constructing self-replicating systems due to its ability to self-assemble through molecular recognition. Here, we show that DNA T-motifs, which self-assemble into ring structures, can be designed to self-replicate through toehold-mediated strand displacement reactions. The inherent design of these rings allows the population dynamics of the systems to be controlled. We also analyse the replication scheme within a universal framework of self-replication and derive a quantitative metric of the self-replicability of the rings. Explore further (—Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature’s building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific chemical interactions that allow for the design of self-assembled structures. In biological systems, DNA replicates with the aid of proteins. However, Junghoon Kim, Junwye Lee, Shogo Hamada, Satoshi Murata, and Sung Ha Park of Sungkyunkwan University and Tohoku University have designed a controllable self-replicating system that does not require proteins. Their work appears in Nature Nanotechnology. To understand how this self-replicating process works, it is important to know the different component parts. Kim et al. designed two DNA T-motifs, r1 and r2, which are double-stranded DNA comprised of functional domains, labeled alpha and beta, and “sticky” ends as connection points. They also designed an extension motif. Twelve units of the r1 motif self-assemble into a small ring, R1, and twelve units of r2 plus twelve extension motifs self-assemble into a larger ring, R2. These components can be in two different states, “fertilized” or “unfertilized”. The fertilized structures contain the features necessary for replication. Fertilization happens when a single-stranded alpha or beta domain of an r1 or r2 motif binds with a strand having a complementary alpha or beta domain. This leaves a single-strand protrusion, or toehold, extending from the ring or from the original motif. The toeholds indicate that the ring or motif is fertilized.These toeholds extending from the DNA ring bind to complimentary invader strands. When this happens, the hybridized structure consisting of the toehold and the invading strand breaks off of the initial ring, and eventually, as these pieces break off due to branch migration, they self-assemble into another ring. This process continues through two different replication pathways. One pathway grows exponentially. The other pathway grows according to Fibonacci’s sequence. The particular pathway taken depends on which invading strands are added to the system.The authors verified that the DNA ring populations grew through this toehold-mediated process with AFM and absorbance studies. For the AFM studies, they took a small sample from each phase and determined the average number of rings present in that phase. Absorbance data was adjusted to determine the relative concentration of rings at each phase. They also verified that the daughter rings were a result of annealing to the single-strand toeholds from the initial ring rather than as a result of self-assembly of residual DNA motifs in solution using gel electrophoresis and extracting the DNA products from each phase. The individual phases were studied with AFM and invading strands were added to a solution during each of the phases to see if rings formed.Kim, et al. demonstrated that nanoscale self-replication can occur using the thermodynamic properties of toehold-mediated strand displacement and the self-assembly abilities of DNA motifs. In this study synthetic DNA T-motifs self-assemble into structures that allow for sequential reactions to take place. This research demonstrates the possibility of functionally programmable self-replicating nanostructures.center_img Journal information: Nature Nanotechnology General principles to explain DNA brick self-assembly This document is subject to copyright.

DOI: 10.1038/s41586-018-0590-4 A very large team of researchers from Stanford University, Chan Zuckerberg Biohub, VA Palo Alto Healthcare System and the University of California has put together an open-source database of mouse cell information it is calling Tabula Muris. In their paper published in the journal Nature, the group describes how information in the database was obtained and the ways in which it might be used. As biological research has progressed, scientists have found that it is useful to gain a more animal-wide perspective when studying the biology of a given creature. In this new initiative, the team has sought to give researchers a more overall view of the biology of mice by creating a database of information about them on a cell-by-cell basis. To that end they used two methods to isolate over 100,000 cells from 20 mouse organs. The first method, called fluorescence-activated cell sorting (FACS) was used to isolate 44,949 cells, while the microfluidic droplet technique was used to isolate another 55, 656 cells. The cells were isolated from several three-month-old mice, offering researchers a road map to the cell biology of a healthy mouse.Isolating cells from all parts of an animal’s body and putting the details into a database allow researcher to study the biology of an animal in a new way. Doing so for a mouse model of Alzheimer’s disease reveals changes throughout the entire mouse, for example, rather than just its brain or its blood. It offers the possibility of learning more about the disease and how it impacts mice, and by extension, people, in a more whole-body sense. It might also lead to better understanding of its cause, and perhaps lead to prevention or a cure. The database could be used to study a wide range of diseases including diabetes, heart disease and even cancer.The group suggests their database could serve as a new tool for biomedical researchers around the world. The work has been sponsored by Chan Zuckerberg Biohub. The organization is also supporting the Human Cell Atlas—an international collaboration geared toward mapping what the group describes as “the basic units of life.” Citation: Chan Zuckerberg Biohub launches Tabula Muris, an open-source database of mouse cells (2018, October 4) retrieved 18 August 2019 from Allen Institute for Brain Science database release nearly doubles mouse brain cell data © 2018 This document is subject to copyright.

first_img Citation: A study of mammalian vocalizations in lead-up to copulations using giant pandas as an example (2018, October 31) retrieved 18 August 2019 from A lot of research has been conducted on vocalizations that are a part of mating rituals in mammals, but what about vocalizations that occur after a potential mate has responded? That is what the researchers with this new effort wanted to know. Do such vocalizations play a role in the success or failure of a given mating attempt? And if so, in what ways? To find the answers to these questions, the researchers chose to study the vocalization rituals of giant pandas as they were about to engage in intercourse.To learn more about how vocalizations are used once a male and female are engaged in the lead-up to copulation, the researchers focused their study on 23 adult giant pandas living near Sichuan, China. The animals were monitored during the breeding season over the years 2016 to 2018. The team used microphones set up in the area to record the sounds the giant pandas made as they went about their courtship rituals.The researchers found patterns in the noises made by their subjects—some noises and the way they were expressed led to successful mating. Other noises, on the other hand, led to failure. They noted also that giant pandas vocalized in different ways—some vocalizations were expressed softly into the ear during intercourse, as one example, an act the researchers described as sort of a love song. They suggest the vocalizations are an important means for achieving synchrony and expressing intentions.The researchers suggest their findings could help those involved in assisting with panda reproduction efforts. It could also help prevent violent conflicts that sometimes arise between giant pandas when mating rituals go awry. Study shows levels of panda hearing A team of researchers from San Diego Zoo’s Institute for Conservation Research and the China Research and Conservation Centre for the Giant Panda has found that vocalizations play an important role in the lead-up to copulation with giant pandas. In their paper published in the journal Royal Society Open Science, the group describes their study of vocalizations leading up to copulation in giant pandas and what they learned. © 2018 Science X Network More information: Benjamin D.

first_imgSubjective Idioms – is a display of surreal and still life through canvas by Nilotpal Dhwaj Sinha and Hans Shinde. ‘Strangers in a strange land’ is the phrase that comes to mind when looking at Sinha’s work. His figures have an odd disconcerting quality about them.While the figures appear highly stylised; sometimes looking like characters from some Japanese caricatures, it is the pathos of their melancholia that makes the works eerily beautiful. Shinde and his series are simple still-life. When it comes to painting, he have always had an inclination to express or depict a subject matter through objects as I find that they reflect the surrounding environment in the most subtle, passive and indirect way. Also Read – ‘Playing Jojo was emotionally exhausting’It is the full frontal gaze of the figures that draws the viewer in. The faces of the people therein wear frightened silences; we see this from their haunted eyes and small mouths. The large eyes indicate fear and passivity, as if they were overwhelmed by some massive sorrow. The small mouth indicates the lack of a voice, in some works the mouth is absent altogether and in another there is just a silent scream, as the mouth remains a mouth no more, morphs into a dark tunnel opening out to the sky above. Also Read – Leslie doing new comedy special with NetflixSinha’s landscape resists interpretation, very much in the same way as a dream reveals to us so much but still leaves us puzzled by its true meaning. These women present themselves to our gaze passively, in their dull, frightened beauty. Yet, despite the gaze and their scars we know nothing about them, while being passively present, it is through their silence that they refuse to reveal themselves, it is the silence of suffering yes, but it is only through it they resist. Artistically, Nilotpal seems influenced by the approach of the Baroda Narrative artists, like them he is interested in particular life narratives, however there are two major ways in which Nilotpal is different. Firstly in his compositional values, while the Narrative movement draws on traditional idioms such as that of the Mughal miniature, Nilotpal draws from popular sources, evoking a comfortable sense of the familiarity of illustrations from a children’s book. And secondly, the ‘local’, ‘mundane’ and ‘bazaar’ elements of the Baroda Narrative still have a sense of familiarity, belonging and comprehensibility. The dream rendering of these Narratives makes them more opaque, incomprehensible, and at times hauntingly nightmarish. He enters Baroda as a stranger in a strange land.For Hans Shinde, the tradition of still life painting is one of the most enduring in the history of art. From the times of the Egyptians when paintings of food and valuables were depicted on tomb walls to the floor mosaics and wall paintings of Pompeii to High Renaissance works of art to contemporary still life painting of today, the genre has always been one that artists turn to again and again.Where: Art and Aesthetic,  Lado Sarai When: December 8 – January 8, 2015 TIMINGS: 11 am till 7 pmlast_img read more
