Royal Challengers Bangalore suffered a major blow hours ahead of their match against Gujarat Lions later tonight when AB de Villiers was ruled out with an injury.Disappointed to be missing the match tonight for RCB, due to injury. Good luck to @imVkohli and the team. Lets go @RCBTweets !!- AB de Villiers (@ABdeVilliers17) April 18, 2017De Villiers, who had hurt his back before the start of the IPL, had to miss the first two matches, before returning to slam a stunning 89 not out against Kings XI Punjab, albeit in a losing cause. He also looked dangerous against Mumbai Indians and Rising Pune Supergiant, making 19 and 29 respectively.(After two weeks of frenetic action, Sourav Ganguly, Michael Clarke pick their XIs for India Today)The South African superstar is one of RCB’s most successful batsmen of all time and peaked last year, smashing 687 runs in 16 matches. (Brendon McCullum 158* brings Royal Challengers Bangalore to their knees in IPL opener)ABD’s unavailability could mean another comeback for Chris Gayle, who has already been dropped from the playing XI. This is a great opportunity for Gayle to become the first man to bring up 10,000 runs in T20 cricket – the West Indian powerhouse is currently three short.

Posture Keeper Yesterday I shared a deal on a desk and a desk chair. Today, let’s talk about how to improve your posture while you’re sitting there.I’ll preface this by saying that I’m a pretty typical desk-bound worker (because writer, duh). And I’ve definitely experienced my share of neck and shoulder pain — some of it severe. I know my chair posture is terrible, alternating between slumping, leaning and rigid uprightness when I catch myself doing the other two.This is pretty common. Lots of people suffer from neck, back and shoulder issues resulting from poor posture. And so Posture Keeper was born. It works with most desk chairs to help you correct your posture — and, hopefully, reduce pain.The PK just transitioned from successfully funded Kickstarter project to commercially available product, and I’ve got an exclusive deal for you. For a limited time, and while a fairly limited first batch lasts, Lifecycle Gifts (via Amazon) has the Posture Keeper for $71.10 with promo code cheapskate10. It’s normally $79.See it at AmazonI realize that’s not much of a discount, but I also think that for anyone who suffers from the kind of desk-related pain I described, even full price is a bargain — assuming the PK actually works.Does it? I’ve been test-driving an early production sample for the past couple months. And I like it — a lot — but with a couple caveats.Imagine putting a backpack over your chair and then putting the straps over your shoulders. Presto: Now you’re effectively strapped to the chair and forced to sit upright — with lumbar support to round out the equation.For me this prevents my two biggest issues: slumping and craning my neck forward. Consequently, I’ve seen a noticeable reduction in neck and shoulder pain. Your mileage may vary, of course, and I can’t comment on how this might affect back issues, because luckily I haven’t had them.Although it’s quite easy to get in and out of the straps, I do find it a hassle sometimes when I need to reach for something across my desk. I’m literally trapped, so I have to unstrap myself, grab what I need, then strap in again. That can be annoying, no question.It also takes a bit of doing to get the Posture Keeper positioned just right. The included instructions are helpful, but plan on some trial and error — possibly over the course of a few days. Once I got it placed to my liking, however, I never had to move it again.I have no idea how this compares with less expensive posture-correcting braces, because I’ve never tried one. I’ll just say that I like the Posture Keeper much more than I thought I would, and it seems to be helping me exactly the way it’s supposed to.Your thoughts?Bonus deal: As you may know, I’m something of a Battlestar Galactica fan. (Just wrapped up a podcast covering the entire series, in fact.) You can currently stream the show on Amazon Prime and Hulu, but if you’d rather own it outright, here’s the best deal I’ve seen to date.For a limited time, Vudu is offering Battlestar Galactica: The Complete Series: Volume 1 (HD) for $14.99. That bundle includes the mini-series, season 1 and season 2. It normally sells for $112 (!).See it at VuduWhile you’re at it (as if you could stop with S2), grab Volume 2 for $14.99 — it completes the series with S3 and S4.If you prefer to stick with Apple’s ecosystem, good news: iTunes also has Volume 1 and Volume 2 for $14.99 each. Wherever and however you watch it, I can’t recommend this show highly enough. It’s in my top five of all time.Bonus deal No. 2: I love mobile chargers that have built-in cables. One less thing to deal with, you know? If you’re an iPhone or iPad user, here’s one you might like.The Olala S102-i comes with an internal Lightning cable and can charge two devices at once. Olala For a limited time, and while supplies last, the Olala S102-i 10,000-mAh power bank with Lightning cable is just $15.05 with promo code OLALA57OFF. It normally sells for $32-$35.See it at AmazonThe MFi-certified cable that accompanies this is fully removable, meaning you can also use it to sync your device if need be. And there’s a secondary USB port for charging additional devices.A few reviewers cited issues with the reliability of that cable, hence the 3.9-star average. However, the S102-i is backed with a one-year warranty, should you encounter a similar problem. For $15 out the door, I’m liking this deal.CNET’s Cheapskate scours the web for great deals on PCs, phones, gadgets and much more.

Physics team entangles photons that never coexisted in time Besides offering a way to create sharper images, the new technique might also prove useful for looking at material that is easily damaged by strong light—it might also lend itself to other types of measuring devices such as interferometers. © 2014 Phys.org More information: An entanglement-enhanced microscope, Nature Communications 4, Article number: 2426 DOI: 10.1038/ncomms3426 . On Arxiv: http://arxiv.org/abs/1401.8075AbstractAmong the applications of optical phase measurement, the differential interference contrast microscope is widely used for the evaluation of opaque materials or biological tissues. However, the signal-to-noise ratio for a given light intensity is limited by the standard quantum limit, which is critical for measurements where the probe light intensity is limited to avoid damaging the sample. The standard quantum limit can only be beaten by using N quantum correlated particles, with an improvement factor of √N. Here we report the demonstration of an entanglement-enhanced microscope, which is a confocal-type differential interference contrast microscope where an entangled photon pair (N=2) source is used for illumination. An image of a Q shape carved in relief on the glass surface is obtained with better visibility than with a classical light source. The signal-to-noise ratio is 1.35±0.12 times better than that limited by the standard quantum limit.

Credit: arxiv.org/abs/1401.8075 Scientists have been using a type of microscope that relies on reading information from pairs of photons reflected off of a surface for several years. The difference between the information provided by each of the photons (the difference in phase) allows for creating an image. The result is stunningly sharp ultra-close-up images of three dimensional surfaces (such as microchips or microorganisms). Until now, however, the resolution of this type of microscopy—known as differential interference contrast microscopy—has been limited by the standard quantum limit—which is based on the Heisenberg uncertainty principle. Scientists have also known for some time that if entangled photons were used instead, they could bypass that limit and create images with better resolution. In this new effort, that’s exactly what the researchers have done.The reason that using entangled photons allow for more information is because measuring one gives information about the other, which results in more information obtained than from two un-entangled photons. The researchers tested this theory by replacing the part of the microscope that emits photons, with one that emitted entangled photons—with it in place they etched the letter “Q” into a glass plate and then proceeded to create an image of it using their new and improved microscope. In so doing, they found an improved signal to noise ratio of 1.35—which can be seen by the naked eye when comparing photographs of the same etching done by both the new and old method. (Phys.org)—A team of researchers with members from Hokkaido and Osaka Universities in Japan has used quantum entanglement of photons to improve image results created using differential interference contrast microscopy. In their paper published in Nature Communications, the team describes how they used entangled photons to enhance an image taken of an etched (to a depth of just 17 nanometers) letter “Q” on a glass plate, and how much improvement was observed.
With the arrest of two persons, who set up a website and duped several Kashmiri youths on the pretext of jobs as crew members and ground staff in Indigo Airlines, the Delhi Police has stumbled upon an inter-state fake job module operating from Central Delhi, the police said on Thursday.The matter came into light when a 22-year-old man, along with 15 other youths, from the Anantnag district of Jammu and Kashmir approached the Jama Masjid police station on March 16. While, two of the identified accused – Irfan and Mohammed Shahid, have been arrested, two others – Amir Shora and Yawar Naik, still remain at large. “We suspect that the module had been working from a long time and have duped hundreds of youths. There could be more members in this module and investigations are underway,” said Paramaditya, Deputy Commissioner of Police (Central). Also Read – Company director arrested for swindling Rs 345 croreAccording to the police, the accused set up a website named Peace Career Consultancy and Job Assistance and advertised themselves through OLX.com. On March 8, the 22-year-old complainant came across the advertisement and applied for the job, for which he first had to meet Yawar and deposit a registration fee of Rs 1,000 at the consultancy office in Anantnag. The next day, the complainant, along with around 50 others were interviewed by Amir Shora, who claimed to be a representative of Indigo Airlines. Soon, the complainant was informed that he has been selected as a ground staff, with a start-up salary of Rs 17,000. But he was also asked to leave for Delhi immediately for the final round of interaction and for collecting the appointment letter.

They lodged themselves in the same hotel in old Delhi’s Jama Masjid area. Meanwhile, the interaction scheduled on March 12 went on getting postponed and on March 15, the applicants were asked to report at the Indigo Airlines headquarters in Gurgaon. When they went there, they were told that there was no interview. That is when they started suspecting the consultant. On March 16, the consultant sent two persons – claiming to be Head Representatives – to the old Delhi Hotel for the final interaction. The job-seekers then immediately asked them to show their identity cards. When they refused, they were asked several questions – like the address of their head office and so – which they apparently had no clues about. The duo then tried to run away when the youths got hold of them and handed them over to the police. They were identified as Irfan and Mohammed Shahid.They have been booked under charges of cheating and other relevant sections of IPC. A team shall soon be sent to Anantnag to nab the other accused, said a police official.
