GE Shows Off 1TB DVDSized Disks at the Emerging Tech Conference

first_img The first products using this technology will be 1TB drives used for archival storage. GE expects this to reach the market in two to three years with another two or more year before it’s available to consumers. GE is anticipating that this technology can store an entire 3D move that would be impossible to store on current blu-ray disk. The holographic drives will have a 3ms access time and data transfer rates up to five times faster than a DVD. Holographic storage involves holograms, images of data being stored in layers on a DVD size disk. The drives work by splitting a laser beam into a reference beam and a signal beam, which is encoded with data. By crossing the two beams an interference pattern is created which is then stored on the disk. Older versions of holographic drives store pages of a million bits stacked ten thousand deep at hundreds of locations on a disk. GE researchers discovered by reducing the page size to a single bit, called micro holograms, they could store as much data per unit area but was much easier to read. It turns out that the upper data layers can be read by a standard Blu-ray player and by slightly increasing the tracking range of the Blu-ray read head all layers can be accessed.GE is planning to license the technology to manufactures for construction of the drives and disk. Peter Lorraine, GE lab manager stated at the Emerging Tech Conference, that license announcements could be expected soon.

Ambient light powered LCD released by Samsung

first_imgImage: ITportal But what if you did not have to plug in your LCD at all? What if it soaked up the light in the room to power itself?Samsung is betting that consumers will be intrigued enough by the idea to make it worth the purchase. They have tweaked their existing transparent LCD technology, it is now energy efficient enough that it can be powered by ambient light alone. That’s right, just the light in the room, no cords and no batteries to replace. A prototype of the technology was debuted at CeBIT 2011. The prototype featured a 46-inch screen that supported full HD resolution video, at 1920×1080 pixels. The screen was also able to act as a full ten finger touchscreen. The company does have plans for commercial models in the works, but they were not too forthcoming with details such as when devices may be available or how much they will cost. This may have something to do with the fact that this technology is still in development. During the demo the touch screen did have some problems.There are some rumors of Samsung using this technology to develop larger panels than the ones currently in existence. The biggest panels that the company currently releases is a 65-inch model. (PhysOrg.com) — Most of us are familiar with LCD technology. You probably have an LCD monitor in front of you right now. There may be an LCD TV sitting in your living room, or bedroom, at this very second. You know that LCD screens come with a power cord. You plug it in and your screen comes to life. © 2010 PhysOrg.com This document is subject to copyright.

USPTO to stage two forums for software community

first_img According to the notice, “While public attendees will have the opportunity to provide their individual input, group consensus advice will not be sought….” As The Verge interprets this, “This is about examining and potentially tweaking the process, not changing the laws.”Nonetheless, the patent office engaging with the software industry on patent issues may prove to be quite beneficial. The conversation may produce concerns by software developers about unjustifiable protections and the need to clarify the vague and broad terms at times evidenced in the filing language used. According to the Register notice, “The USPTO seeks comments on how to more effectively ensure that the boundaries of a claim are clear so that the public can understand what subject matter is protected by the patent claim and the patent examiner can identify and apply the most pertinent prior art.”Software community members who want to attend the meetings need to register by February 4 via e-mail to SoftwareRoundtable2013@uspto.gov but entry will be on a first-come first serve basis. Those applying will need to specify which of the two events they plan to attend. They need to provide their names, titles, and if applicable company organizations, along with their addresses, phone numbers and e-mail addresses. The organizers are also asking those who seek to register to state if they want to make an oral presentation, its topic, and the presentation’s desired length.Both roundtables are to be webcast. Written comments are invited; the deadline for written comments is March 15, after the events have taken place.Already, web site postings of the USPTO’s intentions to invite dialogue through the two events have produced hundreds of comments from software developers. The reactions indicate how heated the topic of software patents has been and will be in the realm of intellectual property. The comments mirror the opinions among those in the software business who have been saying for some time that patents for software are untenable; that they are innovation killers; and that they hurt small businesses that don’t have the deep pockets of software magnates. On the other side, software patent defenders think that patents help, not hinder, innovators by protecting them.The reactions can be summarized as pro, con, and middling. “As a full-time owner of a small software business… the best way to fix them is to ban them,” said one typical anti-patent response. “They are so counter-productive I wouldn’t know where to start.” Another recent respondent said he is sticking to his corporate job rather than doing a startup for fear that somebody is going to try to shake him down for copying what he did not copy.There does appear to be a middle ground between heatedly pro and heatedly con software players.”Nuking software patents is too broad a solution,” wrote one of the recent respondents to news of the forums, recommending instead that efforts to improve software patents be made by involving software engineers as patent examiners. (Phys.org)—Let the conversations begin. The United States Patent and Trademark Office (USPTO) intends to stage two roundtable discussions with developers on the East and West coasts next month to talk about software patents. The notice appearing in the Federal Register, titled “Request for Comments and Notice of Roundtable Events for Partnership for Enhancement of Quality of Software-Related Patents,” invites software developers to express their opinions. The patent office meetings will take place in California and New York. The West Coast roundtable will be held at Stanford University on February 12 and the East Coast event will be held at New York University in New York City on February 27.

Japans IBIS keyhole surgery robot demonstrated w Video

first_img The team of scientists from the Tokyo Institute of Technology (TokyoTech), have been developing their robotics system for some years. It consists of a master unit connected to a slave unit. The master unit is operated by the surgeon, who views the surgery on a stereoscopic 3D display and moves the robot’s arms by means of two finger- and hand-operated joysticks with multiple controls. The slave unit consists of pneumatically driven arms that carry out the delicate surgery.IBIS is unusual in being driven pneumatically, and they say this makes the robot arms more gentle when it touches the patient because the air pressure at the tip of the robot arm can be used to estimate the force being applied. Being pneumatically operated also means the system can be more lightweight and compact than similar electrically operated robots.One advantage of using robots to perform keyhole surgery is that they eliminate hand shake, which can be a problem in this type of minimally invasive surgery, where a steady hand is vital. The force feedback signals relayed to the operator are produced without the need for force sensors, simply by inference from the air pressure at the tip. The lack of force feedback has been a major challenge in the development of successful robot-assisted minimally-invasive surgery (RMIS). A group of robotics scientists in Japan have demonstrated their pneumatic robot, IBIS, which is designed for performing keyhole surgery. They say it may cost as little as one tenth the price of its main rival, Intuitive Surgical’s da Vinci robot. © 2013 Phys.org Associate Professor Kotaro Todano of the Precision and Intelligence Laboratory at TokyoTech recently demonstrated IBIS, and showed that operators had fine control of the arms in manipulating a variety of small objects.The Intuitive Surgical da Vinci robot is priced at around two million US dollars, and the TokyoTech team think their robot will cost somewhere between one tenth and one third of its American rival, partly because it is more compact and pneumatic, but also because many off-the-shelf components are used in its construction. They expect the robot will be available for practical use in four or five years.Via Diginfo TV OB/GYNs told robot hysterectomy not best optioncenter_img Explore further Citation: Japan’s IBIS keyhole surgery robot demonstrated (w/ Video) (2013, July 26) retrieved 18 August 2019 from https://phys.org/news/2013-07-japan-ibis-keyhole-surgery-robot.html This document is subject to copyright.

Researchers demonstrate teleportation using ondemand photons from quantum dots

first_img Journal information: Science Advances Using one quantum dot to sense changes in another Citation: Researchers demonstrate teleportation using on-demand photons from quantum dots (2018, December 17) retrieved 18 August 2019 from https://phys.org/news/2018-12-teleportation-on-demand-photons-quantum-dots.html More information: Marcus Reindl et al. All-photonic quantum teleportation using on-demand solid-state quantum emitters, Science Advances (2018). DOI: 10.1126/sciadv.aau1255 Explore further On-demand photon source and quantum teleportation setup. (A) The radiative recombination of XX-X states provides two photons entangled in polarization if the energetic splitting of the X state, the fine structure splitting (FSS), is sufficiently low. The on-demand generation occurs via a resonant laser tuned to half the energy of the XX state. EB indicates the XX binding energy. (B) Population of the XX state as a function of the pulse area. The experimental data (circles) are modeled as an exponentially damped sine-squared function (purple curve) to determine the depicted preparation fidelity. (C) The autocorrelation measurements for the XX and X transition of a representative QD. (D) The experimental setup for quantum teleportation. A pulsed laser [titanium sapphire (TiSa)] is used to excite two times the QD, which then emits an early pair (PE) and a late pair (PL) of entangled photons separated by Δt in time. The XX and X photons are then spectrally separated by a filter (F). The early XE and late XL pass a HOM Mach-Zehnder consisting of two beam splitters (BSs), performing the Bell state measurement. Polarizers (POLs) and variable retarders (VRs) are used to define the XL input state and XXE detection state accordingly. The three-photon correlation measurement is then recorded as a function of arrival times τ with avalanche photodiodes (APDs). Credit: Science Advances (2018). DOI: 10.1126/sciadv.aau1255center_img © 2018 Science X Network Scientists and many others are very interested in developing truly quantum communications networks—it is believed that such networks will be safe from hacking or eavesdropping due to their very nature. But, as the researchers with this new effort point out, there are still some problems standing in the way. One of these is the difficulty in amplifying quantum signals. One way to get around this problem, they note, is to generate photons on-demand as part of a quantum repeater—this helps to effectively handle the high clock rates. In this new effort, they have done just that, using semiconductor quantum dots.Prior work surrounding the possibility of using semiconductor quantum dots has shown that it is a feasible way to demonstrate teleportation, but only under certain conditions, none of which allowed for on-demand applications. Because of that, they have not been considered a push-button technology. In this new effort, the researchers overcame this problem by creating quantum dots that were highly symmetrical using an etching method to create the hole pairs in which the quantum dots develop. The process they used was called a XX (biexciton)–X (exciton) cascade. They then employed a dual-pulsed excitation scheme to populate the desired XX state (after two pairs shed photons, they retained their entanglement). Doing so allowed for the production of on-demand single photons suitable for use in teleportation. The dual pulsed excitation scheme was critical to the process, the team notes, because it minimized re-excitation.The researchers tested their process first on subjective inputs and then on different quantum dots, proving that it could work across a broad range of applications. They followed that up by creating a framework that other researchers could use as a guide in replicating their efforts. But they also acknowledged that there is still more work to be done (mostly in raising the clock rates) before the process could be used in real-world applications. They expect it will be just a few more years. A team of researchers from Austria, Italy and Sweden has successfully demonstrated teleportation using on-demand photons from quantum dots. In their paper published in the journal Science Advances, the group explains how they accomplished this feat and how it applies to future quantum communications networks.

Curtains down

first_imgEnthralling 16 days, 71 productions and some magnificent plays, 16th Bharat Rang Mahotsav concluded on Sunday and left the Capital’s theatre enthusiasts craving for more drama. The final day concluded with a tamasha. Originally founded to showcase works of Indian theatre practitioners this year the festival catered 7 overseas plays from China, Poland, Germany, Sri Lanka, Japan and Israel.The concluding ceremony took place at Kamani Auditorium with foot tapping lavani with an engaging and interesting plot and story line, performed by Sambhaji Raje Jadhav’s Also Read – ‘Playing Jojo was emotionally exhausting’Loknatya, Maharashtra’s traditional form of folk theatre, tamasha, was the curtain dropper of the biggest theatre festival this year.The plot goes as one day an argument breaks out between Lord Shiva and Goddess Parvati about who and where the best women in the world are. Parvati believes that Lord Brahma’s Savitri, Lord Vishnu’s Lakshmi, and Parvati herself, are the most superior women in the world. Shiva, on the other hand is of the opinion that Maryada Purushottam Rama’s wife Sita, Sati Anusuyya and King Shriyald’s queen Shanguna, are the most supreme. Paravti remains unconvinced of her husband’s view and decides to put Queen Shanguna to the test and the story unfolds. Also Read – Leslie doing new comedy special with NetflixAnother play that was performed by Nation School Of Drama’s Production titled, Clock Work Orange based on the novel by the same name. The novel is dealing with several concerns amongst which are the necessities of free will, the influence of the idea of original sin over environmental behaviourism, the oppression of socialism, the immaturity of youth culture, and so on. Added to this is an under layer of violence in each concern – the violence for identity as envisioned by the state or by the individual. In this performance of Clockwork Orange the performers try to explore the expectation of violence in the making of our own presence—by state or by the individual.The festival saw a gigantic response in every area be it the 3 phase of ticket sale which grossed lakh on the first day, house full boards on almost every show and repetition of plays on public demand. Various seminars and book launches also took place. Apart from the national and international performances that are staged during the Festival also included were exhibitions, installations, interactive sessions with directors and performers for the general public and professionals, a vibrant theatre café, open forums and meetings and a shorter festival in another city to which some of the productions travel.Unveiling a memoirOn Thursday, a book titled Me and My Plays was launched. Written by Mahesh Dattani, a playwright, stage director, screen writer and film maker whose work has shaped contemporary English theatre in India over the past twenty-five years, boldly explored themes like homosexuality, religious fanaticism, child sexual abuse and gender bias in this book.Included in this edition are Where Did I Leave My Purdah? which explores the life and travails of Nazia, a feisty actress now in her eighties, who is forced to confront her past demons when she attempts to stage a comeback, and The Big Fat City, a black comedy about the residents of an apartment complex in Mumbai who unwittingly become accomplices to a murder. Intense and hard hitting, both plays deal with the lies that simmer beneath the surface of our daily lives.Documenting journeysFor the past five years Sanjay Maharshi has been collaborating with the National School of Drama to produce a series of films on the practice and processes of theatre. These films were also released during the festival. The films have been produced keeping in mind not only their academic purpose but also to appeal to theatre students, scholars, and enthusiasts alike.Maharishi is a photographer, editor and producer of documentary films. His films on Habib Tanvir, The Doyen of Indian Theatre, have been widely screened in India and outside. Sanjay’s films have made him travel the length and breath of India.last_img read more

Of film noir

first_imgAmerican Centre, The Embassy of the United States of America, in collaboration with Cinedarbaar is celebrating Coen Brothers Film Festival. Scheduled from 11-13 December at American Centre, will be showcasing the finest works of director-producer duo Ethan Coen and Joel Coen, the most visionary and idiosyncratic filmmakers of the late 20th century.From their Oscar winning Fargo to critically acclaimed Barton Fink, the box office winners Raising Arizona and Inside Llewyn Davis to the classic The Big Lebowski are among the few movies that will be screened in the festival. The Coen brothers are known to be specific to particular regions and communities, Raising Arizona, a comedy cult classic; it paints a very particular picture of the inhabitants of the American South-West. The Big Lebowski (1998) gains much of its absurdist comedy from its depiction of the very absurd Los Angeles community. Also Read – ‘Playing Jojo was emotionally exhausting’The three day festival is an accolade to Ethan and Joel Coen for their remarkable contribution to cinema over the decade and their unique perspective of realms of various genres, adopting appropriate methods of realization to reflect these representational frameworks. The dialogue in their films is a prominent factor in the organization and maintenance of these generic constructions and in the fulfilment of specific stylistic strategies. The Coens have been drawn to two seemingly irresolvable modes of expression: ethnographic regionalism and artificial fabrication. It is between these two extremes that the remainder of their films can be mapped. Also Read – Leslie doing new comedy special with NetflixThe interactive sessions after each screening will discuss about direction aesthetics and thematic of the movies. Working with his brother Ethan, screenwriter/director Joel Coen has specialty of combining thoughtful eccentricity, wry humor, arch irony, and often brutal violence, the films of the Coen brothers have become synonymous with a style of filmmaking that pays tribute to classic American movie genres — especially film noir — while sustaining a firmly postmodern feel. Beginning with Blood Simple, their brutal, stylish 1984 debut, the brothers have amassed a body of work that has established them as two of the most compelling figures in American and world cinemas.When: 11-13 DecemberWhere : American Centrelast_img read more

A 60000 strong exodus Curtains drawing close over CPMs existence in Bengal

first_imgKolkata: At a time when top CPI-M leaders are holding the party Congress in Hyderabad to determine the tactical line which the party will follow for the next three years, Bengal, once a red bastion, is showing a gloomy picture with 60,000 workers leaving the party in the past one and a half years.The organisational report presented at the party Congress shows that since the 2016 Assembly polls in Bengal till now, 60,000 workers have left the party. Of these party members, around 15,000 idle ones have been dropped by the leadership itself, while the remaining 45,000 members have not renewed their membership. Also Read – Heavy rain hits traffic, flightsThe huge fall in the number of members has also affected the financial health of the party badly.It may be mentioned that a few days ago, Chief Minister Mamata Banerjee had criticised the senior leaders of the party for their failure to stop the exodus of their cadres to BJP.Political experts said there are three reasons responsible for the present situation. The party was thrown out of power in 2011 by Mamata Banerjee. Instead of trying to repair the shortcomings that had led to their defeat, party leaders tried to convince the workers that Trinamool Congress would not be able to come back in the 2016 Assembly polls. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe unofficial alliance with Congress was not liked by the majority of the party workers. The party had bagged only 28 seats out 294 in the Bengal Assembly. The frustrated and dejected party workers had started leaving the party en masse in East and West Midnapore, East and West Burdwan, Bankura, Purulia, Hooghly and Howrah. Most of the local committee offices in these districts are still closed as there is none available to open them.Secondly, the party is losing significance in all India politics. Even in the Hyderabad party Congress, the main issue is whether the party will have alliance with Congress in future. The difference between Sitaram Yechury and Prakash Karat over the issue, which is being reported in the media, has also affected the morale of the workers. Lastly, the development carried out by Mamata Banerjee in rural areas has also given benefits to the families of CPI-M supporters. The cycles under Sabuj Sathi or scholarships under Kanyashree or Sikshashree have helped the student community in rural areas immensely. Initially, CPI-M leaders had tried to convince people that poor quality bicycles are being given to the students. But over the years they have been proven wrong. Political experts feel it is almost impossible for the party to turn the situation around in Bengal. They maintained that the same situation will follow in Tripura, another erstwhile stronghold of the party.last_img read more
