Wilkinson signs short Stoke deal

first_img Wilkinson has not featured for the Potters since sustaining a bang on the head in the FA Cup defeat at Blackburn in February. A brief club statement read: “Stoke City can confirm that Andy Wilkinson has been given a contract until December 31, 2015 to enable him to regain full fitness with the support of the club’s medical staff after sustaining an injury last season.” Stoke defender Andy Wilkinson has signed a short-term deal with the club to enable him to recover from a serious head injury. Press Associationcenter_img Wilkinson, who has spent his entire career at his hometown club since progressing through the academy, was out of contract and waved an emotional goodbye to fans at the end of last season. The 30-year-old has made over 190 first-team appearances for Stoke since making his debut in 2001 and has had loan spells at Telford, Partick Thistle, Blackpool and Shrewsbury. He is hoping to return to competitive action in January. last_img read more

Apparent roadblock in the development of quantum lithography

first_img © 2010 PhysOrg.com (PhysOrg.com) — Just when it began to appear that scientists had found a viable way around the problem of the blurring that occurs when using masks to create smaller and smaller silicon wafers for computer chips, a previous study on beam splitting optics showed that the new approach would not work, at least as it has thus far been proposed. A group of researchers explain why in a paper in New Journal of Physics. Quantum electronics: Two photons and chips Currently, the silicon wafers that make up computer chips are made by the process of lithography, whereby optics are used to create an image on a piece of wafer. To create the channels that make up the transistors, masks are used to prevent some of the photons directed towards a wafer from arriving. When the wafer is then immersed in special chemicals, the parts that were struck react differently than those that weren’t, creating the channels. The problem is in the clarity of the image produced on the other side due to the use of optic lenses to focus the photons, as some degree of blurring will always occur due to the nature of lenses. As researchers try to make smaller transistors, the blurring eventually becomes a roadblock, which is why some are looking for alternatives.One such approach is to take advantage of the unique properties of entangled photons; those wily quantum particles that for some inexplicable reason, tend to mimic the behavior of one another, without any apparent means of communication, and at a rate faster than the speed of light. Because they are correlated, the thinking went, they’d always arrive at the same place at the same time (in this case a sensor) creating a near perfect image; so if say a mask were made, in this case a simple one with just two slits in it; it would make sense that the pair of entangled photons would interfere with one another as they tend to do, as they pass through the slit, then arrive together on the other side at exactly the same place and time, which is just what you’d need if you wanted to impact the material on the other side to create your wafer the way you intended. Unfortunately, things haven’t worked out quite that way, because as it turns out, while you can expect a pair of entangled photons to do their thing simultaneously, you can’t rely on them to arrive at the same target, or again in this case, the same sensor, while they are doing so; which of course is a big problem if you’re trying to make a wafer where the photons have to hit their target not only at exactly the same time, but in exactly the right place or you’ve got nothing to show for your efforts.Even so, researchers hoped that enough photons would arrive in the same place at the same time by chance to allow for the process to work; but this meant adding in an exposure time (waiting for enough of the photons to arrive at the same place) which as it turned out rose too rapidly as the feature size requirements went up, making the process unfeasible.While it appears the original idea for using entangled photons for the development of quantum lithography won’t work, researchers aren’t giving up hope just yet; the stakes are too high. The hope now is that some other new imaginative way can be thought of to get around the problems encountered, allowing for the creation of almost unimaginably small chips.

Phys. 13 043028 doi:10.1088/1367-2630/13/4/043028AbstractQuantum lithography promises, in principle, unlimited feature resolution, independent of wavelength. However, in the literature, at least two different theoretical descriptions of quantum lithography exist. They differ in the extent to which they predict that the photons retain spatial correlation from generation to absorption, and although both predict the same feature size, they vastly differ in predicting how efficiently a quantum lithographic pattern can be exposed. Until recently, essentially all quantum lithography experiments have been performed in such a way that it is difficult to distinguish between the two theoretical explanations. However, last year an experiment was performed that gives different outcomes for the two theories. We comment on the experiment and show that the model that fits the data unfortunately indicates that the trade-off between resolution and efficiency in quantum lithography is very unfavourable. Explore further When sending two photons through a double slit they will produce an interference pattern on a detection line after the slits. Denoting the arrival position of the photons with s and t one can plot the detection probability where lighter colour indicates higher probability. If the photons are constrained to arrive at the same place the left figure applies; if they propagate independently the right figure applies. Image credit: New J.

Slew of measures to help speciallyabled voters

first_imgKolkata: Election officials of the North Kolkata Parliamentary constituency segment have initiated various steps to reach out to the specially-abled voters under its jurisdiction and encourage them to exercise their electoral franchise.Braille-enabled Electronic Voting Machines (EVM) will be arranged for visually-impaired voters, officials are visiting the homes of the specially-abled persons to know about their disabilities and locations, a ramp will be put up on the ground with handrail so that wheelchairs can be rolled on the them and some of them will picked up from home and dropped back after the voting process.

The district election officer (DEO) of North Kolkata, Dibyendu Sarkar, has already directed the other election officials to make all the necessary arrangements to ensure a pleasant voting experience for all the specially-abled voters. The officials have also been asked to chalk out a detailed plan to help differently-abled voters to exercise their franchise without any difficulties. Also Read – Lightning kills 8, injures 16 in stateThe office of the DEO has already carried out a survey to identify these voters and their locations in order to make special arrangements for them on the day of poll. The poll personnel have started visiting their homes to know about their disabilities and what kind of assistance they would need to reach polling booths to cast their votes. They have been asked to collect details of the locations and contact numbers of such voters. According to district election officer Dibyendu Sarkar, there are altogether 1,500 differently abled voters in North Kolkata. The election officials have prepared a list of these voters with the data provided by the Kolkata Municipal Corporation and the office of the commissioner for persons with disabilities. “We are making necessary arrangements for the differently-abled voters at the polling stations. A ramp will be put up on the ground with handrail so that wheelchairs can be rolled on the ramp. Voters with physical deformities need not to stand in the queue and they will be allowed to cast their votes the moment they step into the booth,” Sarkar said. Sarkar further said: “Braille-enabled Electronic Voting Machines will be arranged for visually-impaired voters. There will be special arrangements for elderly voters as well. We have decided to arrange 150 wheelchairs in North Kolkata. Vehicles and wheelchairs will be arranged for persons requiring special assistance. We have already spoken to various organisations and NGOs to arrange for wheelchairs. Arrangements will be made to pick up these individuals from their homes and drop them back after voting.” An audio-visual documentary for specially-abled people has been released by the District Election Officer where these voters have been urged to cast their votes. The video will encourage the specially-abled people to take part in the election process, said a senior election official.last_img read more
