Citation: Prospecting for Scientific ‘Gems’ with Google (2006, May 3) retrieved 18 August 2019 from https://phys.org/news/2006-05-prospecting-scientific-gems-google.html So how can one calculate the GPR of any site when you first need to know the GPR of all its neighbors? It’s not a problem to be solved by pencil and paper! The answer is found through a recursive calculation: every website in the network is initialized with the same GPR, so that a new GPR can be calculated for each website simultaneously. This calculation is repeated until all the values stabilize.Researchers Patrick Chen and Sidney Redner at Boston University, along with their colleagues Huafeng Xie and Sergei Maslov at Brookhaven National Lab, recently applied the PageRank algorithm to all 353,268 articles published by the Physical Review between 1893 and 2003. It comes as no surprise that on average, GPR correlates nicely with the citation index. More interesting are the outliers—those articles that somehow achieve a high ranking with relatively few incoming references.After applying PageRank, Chen et al. sorted the papers in this network by their GPR values. Their recent article provides a sampling of famous papers from the top hundred results. Number 85, with only three citations, is a startling poster child of this new approach! The paper in question is a classic example of delayed influence. While it was the first to present a model which today sees widespread use, its result was refined and popularized by other researchers in a separate article. The “child paper” has accumulated 680 citations but makes only ten references to other works itself. The original paper thus collects a large share of its child’s impressive impact.Nor is this the only example! Among the papers with over a hundred citations, most of the papers with an unusually high GPR are easily recognizable as seminal works. Such works compare favorably in overall influence with the very small population having over a thousand citations.While “influence” may be easy to measure crudely, it is hard to measure reliably. These results show that although the two methods are comparable, Google’s PageRank algorithm seems to identify important scientific papers more reliably than a simple citation index. If there is a lesson here, it is this: in giving due credit, one should not be short-cited! Reference: Patrick Chen, Huafeng Xie, Sergei Maslov, & Sidney Redner 2006, “Finding Scientific Gems with Google”, xxx.lanl.gov/physics/0604130By Ben Mathiesen, Copyright 2006 PhysOrg.com Science is all about quantitative measurement, so it should come as no surprise that scientists have a long tradition of measuring their influence on each other. Traditionally, the most important measure of scientific impact has been the number of citations an article receives — but this method’s chief virtue is its simplicity. The authors of any given paper are much more likely to reference recent works, so a result whose importance is not immediately recognized can end up with a much lower citation index than it deserves. A well-written and relevant paper is typically referenced by two or three dozen papers, mostly from researchers working on the same highly specialized problem. A particularly useful or innovative result will often receive a hundred or more citations. Seminal works can achieve over a thousand citations, although they usually take decades to reach that point. While the system works well overall, it has no way of distinguishing a highly relevant citation from the polite mention of a colleague’s work.Many articles, for example, include an introduction section describing the history and current status of their specialized subject. This section can easily generate up to half of a paper’s references, even though few of the results given mention are actually used.A database of scientific literature is very similar in structure to the World Wide Web. Just as individual web pages are connected to each other by one-way links, journal articles are connected to each other by one-way citations. The number of external sites linking to a given website, or “in-degree”, is equivalent to the citation index of a given article. When Google tackled the problem of ranking websites by their influence, it didn’t consider the in-degree to be an appropriate measure. This would make it too easy to inflate the importance of a site by creating a host of useless linking pages. Instead they crafted a customized statistic, the Google PageRank (GPR) algorithm.To illustrate this algorithm, consider the webpage PhysOrg.com. PageRank finds every other webpage with a link to PhysOrg.com, and divides each neighbor’s GPR by its total number of outgoing links. The GPR of Physorg.com is then calculated as the sum of all these factors. In other words, each site in the network can be thought of as evenly distributing its influence over all the sites that it links to. A page thus gains influence mainly by being associated with other influential pages. (The actual algorithm is a little more complicated, but this is its essential feature.) This method strikes a nice balance between content and connectivity, reducing the influence of high-traffic directories on the sites that they list.
Samsung Shipping Samples of New High-capacity NAND Solution to Mobile Customers Explore further The removable SD flash card is only 1 mm thick and 0.7 mm high and will come into production in February. The card comprises a card controller and eight 30-micron thick stacked chips. Samsung says it is the highest capacity microSD ready for production. Users will be able to insert the 32-Gbyte micro SD card into their phone or other device via the built-in micro SD slot. The 64-Gbyte flash chip is 1.4 mm thick and consists of sixteen stacked chips and a storage controller. This moviNAND embedded memory module has been in commercial production since December last year and will be the first to reach the marketplace. It doubles the memory of current memory modules such as that in the latest Apple iPhone.Higher capacity devices such as Samsung’s new offerings will allow mobile devices such as smartphones and media players to have increased memory, and demand for more memory is expected to increase as the market for mobile devices and the applications they run continues to grow. Executive President of Memory Marketing for Samsung, Dong-Soo Jun, said the new memory solutions will bring the storage capacity of computers to mobile devices.The expected cost of the two new high-density storage devices has not been released. (PhysOrg.com) — Samsung Electronics has announced two new flash chip storage devices for mobiles: a removable 32-Gbyte micro SD (secure digital) card and a 64-Gbyte moviNAND flash memory module. Both are based on Samsung’s own 30 nanometer class 32-Gbyte NAND flash memory chips, which use lithography technology that allows much more storage in a smaller unit. © 2010 PhysOrg.com Samsung 32GB microSD memory card Citation: Samsung’s new flash chips for mobile devices (2010, January 14) retrieved 18 August 2019 from https://phys.org/news/2010-01-samsung-chips-mobile-devices.html This document is subject to copyright.

Kolkata: Bengal government is going to reserve seats up to 30 percent for the students having domicile in the state and aspiring law students.Seats would also be reserved up to 5 percent for the poor meritorious students in the same field. The West Bengal National University of Juridical Sciences (Amendment) Bill, 2018 has been passed in the Assembly on Tuesday. It would allow the state government to reserve the seats for the students from the state. Also Read – Rain batters Kolkata, cripples normal lifeMoloy Ghatak, the minister of Judicial and Law Department, said in the Assembly on Tuesday that there are many law aspirants in the state who are unable to pursue law studies due to poverty. The minister said many students from the state will get the opportunity once the law is enforced. Ghatak also clarified that the students would secure admission in West Bengal National University of Juridical Sciences on the basis of merit — a test is conducted at the National level. Despite having being featured on the merit list, many poor but meritorious students cannot afford to study law. This had prompted the state government to amend the existing law of the state.

Seats would be reserved up to 30 percent for the students who have domicile in the state, if they find place on the National merit list,” Ghatak said in the Assembly. The minister also maintained that his department had approached Chief Minister Mamata Banerjee saying there are many students from Bengal who have been able to pursue law studies as they are economically challenged. After listening to the proposal, the Chief Minister assured that steps would be taken in this regard. It may be mentioned that earlier there was no provision in the law which could have allowed the state government to reserve seats for the candidates having domicile in the state. Some other states give opportunity to the students having domicile in their respective states, the minister told the House on Tuesday. While the Bill was tabled in the Assembly, Snehasish Chakraborty, a Trinamool Congress MLA said this move by the state government would be extremely beneficial for the students domiciled in the state. He also alleged that the Left Front government never thought of amending the law, paving way for the poor students to study law.
Kolkata: Chief Minister Mamata Banerjee, while convening a district review meeting in Namkhana, expressed her dissatisfaction over non-completion of the power Grid project at Bhangar in South 24-Parganas.Banerjee sought explanations from the Power department officials on why the project has not been completed yet. She also pulled up Sunil Gupta, additional chief secretary of the Power department and demanded an explanation from him regarding the delay. Also Read – Rain batters Kolkata, cripples normal life”Why has there been a delay when the state government has resolved the issues related to the construction of the power grid?” questioned an irate Chief Minister at the meeting. The Power department officials in the district told the Chief Minister that the project has been delayed due to some technical problems, which will be resolved soon. Meanwhile, the local residents on Thursday morning staged a protest demonstration at the project site, stalling the construction of a tower within the compound. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedSome local residents gathered outside the power grid site, raising their voice to fulfill certain demands. Some of them alleged on Thursday that other development projects which were promised by the government earlier have been stalled as well and hence they would not allow the power project to continue. A high-level meeting would be conducted in the area in this regard. Senior police officers in the district rushed to the spot following the agitation. Some of the villagers, who are members of the Jami Jibika Bastutantra O Paribesh Rakshya Committee (JJBPRC), alleged that the local administration had assured them that dredging of river would take place and a hospital would be set up, but nothing has happened. After a logjam in the power grid project in Bhangar for some time, the matter was finally resolved following intervention of the Power department and administrative officials in the district. JJBPRC members claimed that the government had agreed to meet certain demands of them, including the introduction of vocational training for the unemployed youths in the area and also setting up a cold storage for fishermen and farmers. They alleged that their demands were not properly met. The villagers also alleged that some miscreants have been threatening to resort to violence once the project gets completed. They threatened to stall the project if their demands are not met. A member of the JJBPRC said that they have allowed doing some work inside the sub-station and final decision would be taken on Friday. After a long process of dialogue and deliberations, the government was finally able to resolve the issue and the project was finally flagged off in August this year. The state government has agreed to increase the amount of compensation to people who will lose their land due to the project.
