Raspberry Pi wants to inspire young people to start technology careers. User-focused lessons on how to write letters or enter data on Excel spreadsheets may be fine but the devices will place students on a learning and discovery track closer to computer science than end-user skills. The students would receive these credit-card sized computers and courses would be structured around their use. A posting on the Raspberry Pi blog this week revealed the announcement that the computers are almost ready, seen as good news by many who have been watching for progress updates. The posting said the first finished circuit boards had arrived and that test versions are to be put through electrical, software and hardware testing. If all goes well, volume production will kick in and orders for the computers will also be taken early next month.This week’s arrival of the circuit boards is treated as a milestone, as the bare bones circuit boards are the first to be populated with all the components to go into the finished product. Mice, keyboards, network adapters and external storage connect via USB hub. The computer can be plugged into a TV or monitor and keyboard. Explore further This document is subject to copyright.

Lett. — 10 May 2012 — Volume 48, Issue 10, p.582–583. dx.doi.org/10.1049/el.2012.0849AbstractDirect intensity modulation and wireless data transmission characteristics of terahertz-oscillating resonant tunnelling diodes (RTDs) is reported. A direct intensity modulation of the RTD oscillators was demonstrated, and the frequency response was measured. It was found that the 3 dB cutoff modulation frequency was limited by the parasitic elements of the external circuit, and increased up to 4.5 GHz by reducing such parasitic elements. Wireless data transmission by direct amplitude shift keying was demonstrated using an RTD oscillating at 542 GHz with cutoff frequency of 1.1 GHz. The BERs for bit rates of 2 and 3 Gbit/s were found to be 2×10−8 and 3×10−5, respectively.

Research sites performing imaging make use of terahertz because it is a less damaging alternative to x-rays, in that terahertz waves can penetrate materials but deposit less energy. Outside such settings, where heavy and costly machines are at work, the spectrum has not been considered as a practical solution for daily use. The researchers’ work may make such considerations plausible. The team developed specialized hardware that was capable of achieving the 3Gb data transmission. They made use of resonant tunneling diode, which produces smaller voltages with increasing current, i.e., the voltage decreased as the current increased. “By tuning the current, the team could make the device resonate and spit out signals in the terahertz band,”as Gizmodo commented.Findings of the T-ray researchers, who are from the Tokyo Institute of Technology, have been, published in Electronics Letters. The study suggests that Wi-Fi using the system may support data transmission rates of up to 100 Gbit/s. The researchers note that terahertz Wi-Fi, however, would probably only work for ranges up to 10 meters, but data transmission within that range would be orders of magnitude higher than current alternatives. Their research is still a work in progress, and they intend to extend the range.Beyond their research, Wi-Fi watchers expect favorable progress to come from the new standard 802.11ac, which is said to be the next evolutionary stage of wireless networking.

(Phys.org) — Wednesday headlines trumpeted how “Japanese researchers smash Wi-Fi records” and “Scientists show off the future of Wi-Fi.” The excitement is for good reason. A team of scientists have broken the record for wireless data transmission. They showed that they were capable of transmitting data at 3Gb/at frequencies up to 542GHz. They have done so in uncharted territory, so to speak, the terahertz band, a part of the electromagnetic spectrum that is currently unregulated. They reported success in making Wi-Fi twenty times faster. Location of Terahertz waves in the electromagnetic spectrum. Image: Wikipedia. © 2012 Phys.Org
Changes in optimized traffic in the central London subway network after the removal of the station “Bank” (black node). The corresponding costs are γ= 2 (A) and γ= 0.5 (B). Nodes and edges that show an increase (decrease) in traffic appear in red (blue), where their size and thickness correspond to the magnitude of increase (decrease). Nodes and edges with no traffic changes appear in white and black, respectively. Passenger source–destination pairs are identical to those of Fig. 3 [cf. paper], except for the removal of pairs starting or ending destinations in Bank. Copyright © PNAS, doi:10.1073/pnas.1301111110 Finding a single optimal route is easy, but optimizing the combination of multiple routes is a challenge found in a wide range of applications including Internet instant messaging, peer-to-peer networks, subway traffic, airport flight management, water distribution systems, sensor deployment, military convoy logistics, and trip planning. Historically, due to the computational complexity of deriving a global path optimization (that is, one that simultaneously considers all path possibilities), existing routing algorithms typically optimize each paths in isolation. As a consequence, the resulting solutions are less than optimal. Recently, however, scientists at Aston University, United Kingdom and The Hong Kong University of Science and Technology used the physics of interacting polymers (large molecule composed of many repeated subunits, known as monomers) and disordered systems to analyze macroscopic properties of generic path optimization problems. By so doing, they derived a simple yet global, routing algorithm capable of simultaneously considering all individual path alternatives. The researchers then demonstrated the algorithm utility by applying it to Internet-like random graphs, travel on the London Underground, and the global airport network. Moreover, their analysis revealed phase transitions, scaling laws, non-monotonic growth (that is, not always stable or increasing), and other new routing phenomena related to physics.

David Saad and K. Y. Michael Wong, conducted – and the challenges they face – with Phys.org. “While, employing tools in physics to solve the system analytically was indeed our most difficult task,” Yeung tells Phys.org, “the analogy between polymers and paths is actually easy to understand. A polymer is a long molecule chain likes a string with two ends,” he illustrates, “Suppose I represent my travel path by a polymer: the two ends will be fixed representations of my starting point and destination, and the polymer body will be flexible depending on my path choice. If every traveler represents their path this way, we’d have a system of polymers on a transportation network – meaning that to suppress congestion, we’d introduce a repulsive force between polymers to discourage users using the same route. On the other hand, to encourage passengers share their path we’d introduce an attraction.”Turning now to their analytic work, Yeung points out that polymer paths are non-local variables, which are more difficult to analyze compared to local variables and interactions in conventional physics models. In addition, he notes that all polymers share the same network infrastructure and any two of them may have overlapping paths. “In our transportation network, when polymers overlap they either interact through an attraction or repulsion. It is thus equivalent to say that any two polymers may interact,” Yeung continues, “and the extent of that interaction depends on the extent of overlap, which is again a non-local consideration regarding all polymers. With all these complications, we had to select the best paths out of all possible individual choices as well as their mutual overlapping.” Compared to ordinary polymer systems (which do not allow overlap), they researchers had a much larger pool of possible states, and thereby a much more difficult question to solve. “After deriving our theoretical results,” Yeung adds, “we obtained the algorithm directly – and testing it on several datasets, found very good results. Once the system was analytically solved, it was straightforward to find its macroscopic properties, such as average path length and energy, by ordinary physics techniques in our area.” One key insight the scientists had, says Yeung, was that while some may think that the shortest path is always the best choice, this is not the case – and in fact, usual choice of going through the shortest path is a bad one when everyone takes the same route. “This isn’t difficult to understand, as some observers may have already noticed. For example,” Yeung illustrates, “during peak hours, some popular routes which lie on the shortest path may be overloaded, causing delays and making this path slower than a slightly longer one.” Yeung points out that their simulations with the London metro data show that – compared to when all passengers travel through the shortest path – if they introduce a repulsive force between passenger paths, and if passengers follow the suggested path, 20% of the assumed cost can be saved at a price of only 6% increase in average path length. “On the other hand,” Yeung continues, “although congestion does not occur in off-peak hours, the shortest path is still a bad choice, because the whole network has to remain active even for reduced usage on the less popular routes. Suppose we encourage off-peak commuters to travel on some common routes and share a large part of their journeys; then, the less popular bus routes or train lines can be discontinued which saves a lot of energy.” Yeung adds that their results show that they can obtain such optimized shared path configurations through the analogy to an attractive polymer system.Other than these results, the scientists also found that when they gradually change the polymer interaction from slightly repulsive to slightly attractive, there is a sharp increase in the number of idle nodes. “This is similar to a discontinuous phase transition observed in other physical systems,” Yeung says. “Surprisingly, while the average path length does not change much, it does have an important implication on transportation or communication networks – that is, one can greatly increase the number of idle nodes without significantly lengthening the average path length, by introducing a slight attractive force between passenger paths. This may save a lot of resources in sparse traffic scenarios.”A key aspect of the researchers’ results was demonstrating the algorithm’s efficacy by applying it to random graphs resembling Internet overlay networks – that is, computer networks built on top of another network, in which nodes can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network. “Networks representing websites interconnected by hyperlinks, or friends linked by instant messengers, are usually not bounded by physical location,” Yeung notes, “and are well described by some specific random structures. We show in a simple random network how we can find the best choice of communication paths according to the attractive or repulsive strength we introduced.”In the case of repulsion, Yeung explains, individual communication paths avoid each other and at last almost everyone has its own path not overlapping with the others. In the case of attraction, the communications go through a small common region of the network, sharing their paths and leaving a lot of other nodes and links idle. “If we consider the idle nodes as routers,” he points out, “a lot of energy can be saved by switching them off.”The researchers also applied their findings to travel on the London Underground network based on Oyster card data. “If we compare to the case where everyone takes their shortest path,” says Yeung, “our simulations show substantial improvement on the London Metro network. Again, at a price of only 6% increase in average path length, 20% and 4% of the assumed cost are saved on the London metro network when one aims to balance or consolidate traffic, respectively. Of course, in practice,” he acknowledges, “some experienced users would adopt a smarter route than the shortest path and the benefit from our algorithm would be less. However, I believe that in many transportation or communication networks there is still a large room of improvement in terms of energy saving if individual paths are well coordinated.” Yeung adds that they did a very similar experiment, and obtain a similar result, in the global airport network.Regarding other innovations that the scientists might develop and apply to the current experimental design, Yeung says that since physicists usually start with a generic model of physical systems, they’ve also assumed a model of interacting polymers which accommodates different type of interaction. “It turns out that we obtain a single algorithm which achieves various goals by tuning a single parameter controlling the attractive and repulsive strength between polymers,” he explains. “Indeed, our approach can take into account interactions other than attraction and repulsion, and which may have other interesting applications. We welcome networking experts to suggest other specific routing problems which our algorithm may be able to tackle.On the practical side, Yeung continues, one idea may be to develop a real-time application, based on their algorithm, to globally coordinate paths for individuals who start their journey at roughly the same time. “It’s not the same as the usual route-finder applications that simply identify the shortest path for individuals without their interactions with others,” he explains. “Rather, the envisioned application would coordinate routes for many individuals who travel at the same time in order to achieve goals like balancing highway or tunnel usage, or to encourage train or plane sharing in off-peak hours or seasons.”Yeung also describes the planned next steps in their research. “Our path solution is static.” He notes. “In other words, it provides an optimized path configuration given a set of destination pairs, and so suits many applications – but not those where the amount of traffic between individual destination pairs is rapidly changing. The next step is, perhaps, to develop routing algorithms based on our framework which address a dynamical routing task.”Yeung notes that other areas of research that might benefit from their study. “Our generic routing algorithm is applicable to any application that involves the path selection and coordination of individual paths,” he tells Phys.org. “I hope our work can contribute to routing problems in transportation and communication networks, as well as sustainability research where the fixed infrastructure of existing transportation or communication systems is better utilized, thereby reducing the needs for further construction. In a more general respect,” Yeung concludes, “I hope that our work demonstrates the power of rigorous physical tools when applied to interdisciplinary areas outside the realm of physics.” More information: From the physics of interacting polymers to optimizing routes on the London Underground, PNAS Published online before print July 29, 2013, doi:10.1073/pnas.1301111110 Optimized traffic on the London subway network.

Credit: arXiv:1501.01881 [cond-mat.mes-hall] For several years, material scientists, chemists, physicists and others researchers have been excitedly working to find a way to create graphene in bulk and to force it to have a band gap. Thus far, that work has not led to a breakthrough that would allow the so-called miracle material to be used for much in the way of real world applications. In this new effort, the research team has moved their focus to black phosphorus (aka phosphorene) which has many of the same beneficial traits as graphene, but currently has, at least theoretically, a way to induce a band gap. Up till now, however, making black phosphorus was done the same way as making graphene, e.g. using sticky tape to pull layers off a bulk sample—that is obviously not a good way to produce material suitable for commercial applications. Now it appears the team in Ireland has found another way—one that is simple, inexpensive and allows for separating out different sized sheets.To get sheets of black phosphorus the team created a block of it first, then, instead of trying to rip layers off with tape, they submerged it in a CHP liquid solvent and then piped in acoustic waves, which served to knock off layers of phosphorene (nanosheets) into the solution. The team then filtered the sheets using a centrifuge. Using this method the team reports that they have been able to produce nanosheets of black phosphorus in bulk, some of which are just a few layers thick.The researchers have used the results of their efforts to test the usefulness of using black phosphorus in a variety of applications, ranging from increasing the strength of polyvinyl chloride, to an ammonia detector. They note the nanosheets do suffer from one serious drawback—they tend to disintegrate over a short period of time when exposed to water or oxygen, but the team is optimistic that solvents can be created to provide a protective shell around the sheets that will still allow it to perform its useful functions.

However, its lack of stability severely limits our ability to synthesise and process this material. Here we demonstrate that high-quality, few-layer black phosphorus nanosheets can be produced in large quantities by liquid phase exfoliation in the solvent N-cyclohexyl-2-pyrrolidone (CHP). We can control nanosheet dimensions and have developed metrics to estimate both nanosheet size and thickness spectroscopically. When exfoliated in CHP, the nanosheets are remarkably stable unless water is intentionally introduced. Computational studies show the degradation to occur by reaction with water molecules only at the nanosheet edge, leading to the removal of phosphorus atoms and the formation of phosphine and phosphorous acid. We demonstrate that liquid exfoliated black phosphorus nanosheets are potentially useful in a range of applications from optical switches to gas sensors to fillers for composite reinforcement.

Kolkata: The Supreme Court has directed the state BJP to move High Court over the extension of deadline of the last day of nomination for the forthcoming Panchayat election.The State Election Commission had announced the extension of the deadline by a day on Monday. On Tuesday, it had issued a fresh order, cancelling the earlier notification. This had created utter confusion among the Opposition parties and the state BJP had moved the High Court as well as the Supreme Court. Kalyan Banerjee, Trinamool MP and advocate, said it was clear that BJP had suppressed the fact and did not inform the High Court about the move it had made before the Supreme Court. BJP leaders, however, did not turn up on Wednesday.

Kolkata: In a shocking incident, an eighty-year-old man was beaten up by his son in Ashoknagar.Locals informed that Maniklal Biswas (80) had given his wife a crumb of sweets, due to which his son Pradip slapped him repeatedly. Sources informed that Pradip is a staff of the Ashoknagar-Kalyangarh Municipality. Local people said that on Friday, the day of Dashami, Maniklal’s wife had touched his feet as a traditional gesture. In return, he had given her a bite of the sweet which he was having. Also Read – Rain batters Kolkata, cripples normal lifeBut before she could eat, Pradip arrived. Seeing her son she went towards the bathroom and handed over the sweet to Maniklal in fear. But Pradip somehow saw this. He was furious as his mother has high blood sugar and hence needs to refrain from sweets. He immediately dragged his father out of the room and started slapping him. Despite Maniklal apologising, Pradip didn’t bother to pay heed to him and kept on slapping his father. Some neighbours heard loud voices. When a neighbour went to see what was happening, he saw Pradip slapping Maniklal. He immediately took out his smartphone and recorded the whole scene. Later, the video was uploaded on Facebook.

Immediately, Ashoknagar police station arrested him. Maniklal informed that he was being tortured regularly by his son. Though Pradip tried to lighten the matter by seeking apology from his father, the neighbours were not convinced at all. When police arrived, Maniklal gained courage to speak up. He himself told the police what his son did to him. Hearing the whole thing, locals tried to beat him up but police obstructed them. He was immediately apprehended.
