Three AIIMS doctors, two of them women, passed away on Sunday and four others were injured in an accident on the Yamuna Expressway near here, police said.A team of seven doctors from AIIMS were travelling to Agra from Delhi in an SUV which rammed into a canter around 2.30 a.m., they said. While three doctors died on the spot, the four others were rushed to a private hospital here. They were then referred to the AIIMS trauma centre, SP (Rural) Aditya Kumar Shukla said.The speeding SUV rammed the canter and partially entered into it, he said, adding three of them succumbed to injuries on the accident spot, while four injured doctors were rushed to a nearby private hospital for first aid.The deceased have been identified as doctors Dr. Yashprit (25) and Dr. Hembala (about 25), and Dr. Harshad (35) .According to Mr. Shukla, Dr. Jitendra, Dr. Mahesh, Dr. Abhinav and Dr. Catherine were later rushed to the AIIMS. The SP said immediate help was provided as the information reached the police through the emergency number, 100.The canter driver abandoned his vehicle and fled, the police officer said.

Some things are more important than football, and somebody’s personal well-being belongs at the top of that list. Despite how much you may think you know about a person, it’s impossible to know what kind of battles they’re fighting in their own heads each and every day, struggles too painful to share. So on Sunday, when Washington wide receiver Isaiah Renfro courageously took to Twitter to explain the battles he’s been fighting over the past year, the fact that he has decided to step away from football should be the last thing you take from his announcement. Yes – that was one of the reasons for it, but it was so much more than that; it was a young man finding enough strength to open up and be true to himself, true to others. It was what he believes to be a step in the right direction. Been debating on posting this but this is me taking steps in the right direction to becoming myself again.. pic.twitter.com/ptE1k9oKKJ— Isaiah Woods-Renfro (@WaveGodZay) May 29, 2016Here’s the message he posted to Twitter Sunday night. Renfro will obviously be missed on the football field, but I think it’s safe to say he’ll be supported in any way necessary through this difficult time. read more
MONTREAL – It was a game of lacrosse like few get to see: a group of youths, shirtless and mostly barefoot, with no helmets or padding, racing after a leather ball with hand-made wooden sticks.There were no referees, few rules and no line changes — only a wild free-for-all as the boys jostled and shoved, working to fling the ball at the wooden posts at each end.The game, which took place recently at McGill University in Montreal, was organized to celebrate the 150th anniversary of organized lacrosse — and to highlight the game’s First Nations origins, which go back much further.While the rules of modern lacrosse were adopted in 1867, the sport developed from a centuries cultural and spiritual activity practiced by several First Nations tribes.Louis Delisle, a Hall of Fame lacrosse player who hails from the Kahnawake Mohawk territory south of Montreal, said it’s impossible to know when the game started.“But what’s important is we all played it, and called it the creator’s game because was a gift from the creator,” he said in an interview.He said the game was sometimes played with hundreds of players on each side on a terrain that could span several kilometres.“It was a sport but it was also a training ground, a way to develop your endurance, your toughness, your tactics in learning how to use that stick to protect yourself and also to attack your enemy,” he said.In 1867, Canada’s first sports governing body adopted the first official lacrosse rulebook, which had been written by George Beers, a dentist from Montreal who had fallen in love with the game.Nets were brought in, field sizes were reduced and the number of players was standardized, according to Jim Calder, who has authored a book on the sport’s history.But although lacrosse quickly became popular, Calder says no government records exist to prove it was ever officially designated as Canada’s national game.He says while it’s possible the documentation has been lost, it is more likely that Beers simply convinced people to view it that way.“Beers was such a great promoter of the game, and wrote so many articles for so many newspapers on the game, that people naturally assumed that it was given by Parliament as our national sport,” he said.Hockey and lacrosse were only designated as Canada’s national winter and summer sports in 1994.The game played at McGill was part of a series of events organized by Calder and the Canadian Lacrosse Foundation in honour of the modern sport’s 150-year anniversary.It began with a ceremony that included a bald eagle, and featured youths from the Kahnawake Survival School re-enacting a traditional medicine game, played to help heal an ailing community member.One of the 14-year-old players described the no-holds-barred contest as “painful.”“The ball is harder to pick up, harder to shoot, and when you get hit, it hurts,” Rahsakaienhtha Cross said.It was, he added, the best lacrosse game he’d ever played.One of the enthusiastic supporters on the sidelines was Alfred Jacques, a maker of traditional wooden lacrosse sticks like the ones used in the game.Jacques, a member the Onondaga nation from near Syracuse, N.Y., called the 10-month stick-making process a “labour of love” that involves cutting, shaping, drying and steaming the wood before it can be shaped and strung with cow hide.He says the modern game has come a long way when it comes to acknowledging the contribution of First Nations, whose players were once banned from many leagues because they were deemed to be professionals.“There was that resentment right there because this is our game, and you tell us we can’t play,” he said.Now, the 68-year-old says there’s renewed interest in the traditional game.“Respect is coming now, now it is,” he said. read more

Former Arkansas defensive coordinator Chris Ash was named Ohio State co-defensive coordinator and safeties coach Jan. 23.Credit: Courtesy of Arkansas Athletic DepartmentUrban Meyer’s rejuvenated coaching staff might be complete.Ohio State officially announced the hiring of Chris Ash as co-defensive coordinator and safeties coach Thursday, rounding out coach Meyer’s coaching staff for now, according to a press release.“We’ve competed against a Chris Ash defense before and I have respect for him as a coach,” Meyer said in a released statement. “I like the fact he has experience in the Big Ten Conference and that he is a great recruiter. He was highly recommended by everyone I spoke to.”An OSU spokesman said in an email Thursday afternoon Ash is set to earn $520,000 as part of the Buckeyes’ coaching staff, $30,000 less than what he made in his previous position.Ash comes to OSU after spending one year as the defensive coordinator and secondary coach at Arkansas. He is set to replace former OSU co-defensive coordinator and safeties coach Everett Withers, who was named the next head football coach at James Madison University Dec. 20. Withers earned $580,000 this past season at OSU, according to The Lantern archives.“I was attracted to this position because it is Ohio State,” Ash said in a released statement. “And I had to wonder if I ever would have this opportunity again. This is one of the top five college football programs in the country. It has tremendous history and tradition, and it is a great academic institution.“The opportunity to work for coach Meyer and to learn as a part of his staff will absolutely enhance my knowledge of the game and my coaching experiences.”Prior to coaching at Arkansas this past season, Ash spent two years at Wisconsin with former Badgers and current Razorbacks coach Bret Bielema. In 2011, the Wisconsin defense allowed just 163.6 passing yards per game, good for fourth-best nationally. It also ranked 13th in the country in scoring defense, giving up just 19 points per game, and 15th in total defense, allowing 316.3 yards per game.In 2012, the Badgers defense finished ranked 15th in the country in total defense, allowing 322.6 yards per game, and 16th in scoring (19.1 points per game) and 18th in fewest passing yards allowed with 193.6 yards per game. He was part of the coaching staff that helped lead the Badgers to three straight Rose Bowls from 2011-13.Ash will look to bring stability to OSU’s defensive secondary, which finished ranked 112th in the nation last season, giving up an average 268 yards per game.“To be successful, I think you have to be detailed,” Ash said in a released statement. “You have to be able to coach and teach the fundamentals of the game, and that’s how you develop players. You have to have a consistency with how you prepare yourself so you can prepare them and then get them to play hard.”Ash, a 1996 graduate of Drake University who grew up in Iowa, said in a statement he is looking forward to recruiting for OSU.“You can recruit anywhere in the country,” Ash said in reference to the OSU coaches. “You can recruit players that are talented, that have character and that believe education is very important. When you have all three of those attributes in players, then you can build upon this outstanding program.”Ash earned $550,000 this past season at Arkansas, according to the USA TODAY coaches database.The Buckeyes are set to open their 2014 campaign Aug. 30 against Navy at M&T Bank Stadium in Baltimore. read more
Celtic winger Scott Sinclair believes racism is becoming acute in football and should be exposed and kicked out and never to be ignored.Earlier this month, Sinclair was subject of racial abuse but was defended by his club’s coach Brendan Rodgers and thanked the winger for handling the case maturely.Sinclair condemned football racism and adds that football should adopt a zero-tolerance approach to racial abuse.“It’s unacceptable, not just in football or sport but in society generally,” said the 29-year-old via Scotsman.“I think it needs to be kicked out. It needs to stop and to be shown that it’s unacceptable to use racial slurs or to abuse the ethnicity of players.“The cup final incident was on social media. I was flicking through some things and came across it.Match Preview: Manchester United vs Leicester City Boro Tanchev – September 13, 2019 Old Trafford is the venue for the Premier League encounter between Manchester United and Leicester City, which kicks off at 16:00 (CET) on Saturday.“It’s one of those things that just shouldn’t be happening. It’s 2018.”“This is what I don’t understand,” he added“When I tweeted I called them uneducated and that’s what they are. They are uneducated in this area; they have black players in their team so it’s very confusing.“Why would someone use that sort of slur towards black players? It’s embarrassing. It’s not acceptable for anyone in society to even think they can use that sort of language, whether they are at a football game or in the street. But it’s always around and it’s such a shame to keep hearing the racial slurs.“I think there’s more of a spotlight on racial abuse now, especially with [Manchester City’s] Raheem Sterling experiencing it down south and speaking out,” he said. read more

Post a comment Tags Lexus 2020 Lexus RX first drive: Sharper image 2020 BMW 330e first drive: A plug-in 3 Series without compromise Lexus This week, at a Lexus Milestones event held to celebrate 30 years of the Lexus brand, the Japanese luxury automaker gave a preview of its future. This included Lexus’ plans for upcoming autonomous driving technologies and expanding the number of electrified vehicles and powertrains throughout its entire lineup.Speaking to journalists on Thursday, Executive Vice President of Lexus International Koji Sato said, “Between Toyota and Lexus, we plan to roll out 10 EVs by 2025. At the same time, every Lexus model on the road will be available as a dedicated electrified model or have an electrified option.”In this case “electrified” includes a combination of self-contained hybrid, plug-in hybrid, battery electric and hydrogen fuel cell vehicles, all of which are on the table as options for future Lexus models. Ultimately, which technology is chosen for a particular vehicle will depend on the market in which that vehicle is sold and the needs of the vehicle and drivers in question.”There is not one powerplant that will work for the globe. The reality is that different legality and social conditions have created a landscape where automakers must offer a variety of choices,” Sato said. “We will chose for each model based on the demand or background of the market.”Depending on the market and the model, “electrified” might mean hybrid, battery or even fuel cell-powered vehicles. Toyota When asked about fuel cell vehicles, Sato said that “from a technology point of view” the automaker is “very serious about FCEVs,” but is carefully consider the rollout of hydrogen depending on the local infrastructure conditions. So, in the US at least, that landscape will likely be populated by more hybrids, plug-in hybrids and battery electric vehicles.”A proven history mastering battery management, reduced mass components and electric motors offers an advantage that will help us create a dedicated pure EV platform that speaks to the next generation of luxury consumers that do not want to make compromises for performance, excitement, range or capability,” he said.The automaker is already well on its way toward achieving its goal of a fully electrified lineup. Of the 11 models in its portfolio, only five aren’t currently available as hybrids. The IS, RC and GS make sense to hybridize; the GS, in particular, was offered with a hybrid powertrain previously. Speaking candidly with a Lexus representative later in the day, I learned that the GX and LX — Lexus’ two largest SUVs — are tricky because customers expect a different level of off-road and towing capability from a vehicle in this class and the automaker needs to make sure that it meets those expectations with whatever electrification route it takes.Lexus is off to a pretty good start. More than half of its current lineup is offered in hybrid trim. Lexus Fortunately, Lexus’ hybrid technology is continuing to evolve. The new LC400h halo car, for example, features a trick new transmission technology that aims to make hybrid driving more engaging. The automaker is also developing new battery and electric motor technologies, including in-wheel electric motors. Sato explains, “We expect that four wheels operating independently will offer a greater agility, stability and excitement. Of course, in-wheel electric motors are just a concept currently and it will take years to make the technology perfect. But we will continue to pursue this exciting opportunity.”We should learn more about what the future of Lexus electrification will look like at the 2019 Tokyo Motor Show later this year, where the automaker plans to unveils a new electric concept car. I got an early peek — which I sadly can’t share just yet — and it looks… well, intense.

Katrina Kaif in ZeroYouTube screenshotThere’s no denying that Katrina Kaif has gone through a lot of ups and downs in her both professional and personal life but the starlet overcomed the hurdles that came crashing in her path. She is now considered as one of the most desirable actresses in Bollywood and has many hit films to her name. But not many people would know that Katrina had suffered a heartbreak at the age of 17 when she was the new girl in the city looking for a break in the entertainment industry.In the recent episode of Feet Up With The Stars season 2, host Anaita Adajania recalled an incident when she was Katrina Kaif coming to meet her at her office in South Mumbai in a ‘kaali-peeli’ taxi. She quickly asked Katrina if she remembered what she was wearing at that time.Katrina, who was filled with pride by then, narrated the entire incident (with a smile on her face) to the viewers saying, “So I’ve come to Anaita’s office and I’ve gotten out of, not even a cool cab, but a normal one. So I was hot because it’s hot outside. And I was wearing very short shorts and very small top (Anaita then interjects and corrects Katrina saying ‘sheer top’) and Anaita deemed it inappropriate that I was wearing that.”As Anaita corrected her saying that she was worried about her, Katrina continued to narrate the incident, “So she corrected me on it and at which point, I felt very bad. I was like ‘Ohhh’. Anaita added to the story saying that when Katrina started off, she was voluptuous, a lot more curvy and she felt that she was a danger to the traffic.Katrina gave a nod to Anaita and further continued the conversation to explain how she was left heartbroken at 17.”You were worried for my safety but yeah.., so that’s the first time we met and I remember I was trying to book a story. So, as a model in those days, if you get booked for a fashion feature or an editorial or a cover, it’s a big thing. And I had not yet appeared in any magazine. I was 17, and I was really wanting you to put me in this magazine and say that, “Yeah done babe, you’re on the cover, this is the one.” And you were just about to confirm me for a fashion editorial, which basically means, for those who don’t know, that it goes inside the magazine and my poor little heart, my poor 17 years old heart, so small, it was like so crushed and I am like, “Oh, no! Anaita Shroff is not putting me on the cover,” Katrina said to which Anaita quickly replied that cut to that they’ve done some amazing covers together. read more

Rodney Ellis, D-Houston, leads a press conference about transgender students’ rights on May 16, 2016.The Obama Administration has told schools across the country that they must allow transgender students to use the bathroom that matches their gender identity.The new guidance affects dress codes, athletic policies, locker rooms and other rules.What if Texas schools ignore those orders and instead follow the directive from Lt. Gov. Dan Patrick?“We will not yield to blackmail from the President of the United States,” Patrick, a Houston Republican, told reporters last Friday.Then Texas could lose about $5 billion a year in federal money for public schools.Patrick has pledged that state lawmakers will try to cover the difference.But state Sen. Rodney Ellis, D-Houston, said that Texas can’t afford that, especially since the Texas Supreme Court has ruled that children deserve a better school funding system, even if the current one is constitutional.“At a time when the Supreme Court admits that our school finance system is barely scrapping constitutional muster, we can’t afford to walk away from ten billion dollars in federal funding that helps to educate and feed our state’s most vulnerable kids,” Ellis said. (The $10 billion figure refers to funding over a two-year period).“A lot of money is for kids who have disabilities, special needs and also for food programs. Now it’s interesting who folks are picking on. They’re picking on folk who are the most vulnerable in our society,” he added.”Houston school board member Jolanda Jones said that she knows from personal experience how much kids need free breakfast at school.“This is a difference between a need and want,” Jones said. “Kids need to eat, they just do. Kids who don’t speak English need to have someone who helps them with languages.” Jones said that the federal money at stake doesn’t go towards transgender students, and that HISD already has a non-discrimination policy that includes transgender students.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. “All of these 13 logic operations share the same initial state, that is, the molecule is always ‘reset’ to one and the same state by the use of green light, irrespective of which logic function is to be performed,” said Andréasson. “This is another unique feature of our molecule.”The researchers also demonstrated that the FG-DTE molecule can perform non-arithmetic functions. For example, as a digital multiplexer, the molecule can act as a mimic of a mechanical rotary switch to connect any one of several inputs to an output. As a demultiplexer, the molecule can separate two signals that have been multiplexed into one output.Further, the FG-DTE molecule can perform sequential logic functions, in which inputs must be applied in the correct order, such as for a keypad lock. The molecule can also operate as a transfer gate by transferring the state of an input to that of an output, which is useful for complicated computational operations. The researchers also demonstrated that the molecule can act as an encoder and decoder, by compressing digital information for transmission or storage, and then recovering the information in its original form.While each of these individual logic operations has previously been performed by molecular systems, the FG-DTE molecule is the first to unite them all in a single molecular platform. Transistors and other more traditional logic devices do not have the same functional flexibility, which the researchers attribute to the chromophores’ ability to respond differently to different wavelengths of light and to influence each other’s properties.As for applications, the researchers note that it’s unlikely that such molecular devices will soon replace electronic computers, but they could have applications in nanotechnology and biomedicine, such as for data storage, labeling and tracking micro-objects, and programmed drug release.“In the near term, molecular logic devices will complement, rather than compete with, electronic devices,” Gust said. “In principle, molecular computing could be implemented with extremely small switch sizes, since the operational units are molecules. Photonically operated molecular devices such as the one we describe can also be easily reconfigured to perform a variety of different logic functions, can operate at high speeds, and can be arrayed in three dimensions, rather than the planar arrangements usually found in electronics. “Molecular logic devices can be employed where electronic ones cannot,” he added. “For example, they can be used to label and track nanoparticles and nanoscale components of biological organisms. On the other hand, most photochromes currently are not sufficiently stable to stand up to the large number of cycles required for useful full-scale computing. In addition, complex computing will require convenient ways for nanoscale logic devices to communicate with one another.”“In addition, the application of molecular logic in biological systems, such as the human body, is still relatively unexplored, although molecular systems are better suited for this purpose compared to electronic devices,” said Andréasson.In the future, the researchers plan to address some of the biggest challenges facing molecular logic, such as the efficient wiring (concatenation) of logic switches.“One of the major challenges of molecular logic is concatenation of logic operations,” Gust said. “In electronics, this can be done simply by wiring the output of one element to the input of the next. We need to find ways of achieving similar results in molecules.” (PhysOrg.com) — While molecules have already been used to perform individual logic operations, scientists have now shown that a single molecule can perform 13 logic operations, some of them in parallel. The molecule, which consists of three chromophores, is operated by different wavelengths of light. The scientists predict that this system, with its unprecedented level of complexity, could serve as a building block of molecular computing, in which molecules rather than electrons are used for processing and manipulating information.

Read-write device offers new architecture for information processing More information: Joakim Andréasson, et al. “All-Photonic Multifunctional Molecular Logic Devices.” Journal of the American Chemical Society. DOI:10.1021/ja203456h The scientists and engineers, Joakim Andréasson from Chalmers University of Technology in Göteborg, Sweden; Uwe Pischel from the University of Huelva, Spain; and Stephen D. Straight, Thomas A. Moore, Ana L. Moore, and Devens Gust from Arizona State University, have published their study called “All-Photonic Multifunctional Molecular Logic Devices” in a recent issue of the Journal of the American Chemical Society.“While previous examples of molecular logic systems have been able to carry out one, or a few different logic operations, this molecule can be reconfigured to perform 13 simply by changing the input or output wavelengths,” Gust told PhysOrg.com. “In addition, it uses light for all inputs and outputs, which avoids some of the problems encountered when using chemicals as inputs.”In general, chromophores are the parts of a molecule that absorb light of specific wavelengths while transmitting other wavelengths, and are responsible for the molecule’s color. When chromophores can be switched between two different states by being irradiated with light of different wavelengths, they have the ability to perform binary logic operations and effectively serve as transistors. These photoswitchable, bistable chromophores are called photochromes.To thank our 25,000 fans in the Facebook community, this story was posted on the Physorg.com FB page a few hours before going live on the main siteHere, the researchers used three photochromes – one dithienylethene (DTE) and two fulgmides (FG) – to build a light-responsive molecule. Each of these photochromes can exist in either an open or closed isomeric form, and can be switched back and forth between forms with light pulses of different wavelengths. The two forms that each photochrome can take represent the two states that serve as the basis for performing binary logic operations. Various combinations of the three photochromes in different isomeric forms can be used to perform binary arithmetic, such as addition and subtraction. Although previous molecular-based systems have performed binary arithmetic, the FG-DTE molecule is the first that can perform these operations using only two inputs: light with wavelengths of 302 nm and 397 nm. Also, all three photochromes can be reset by green light irradiation (460-590 nm). These features allow the molecule to perform addition and subtraction in parallel, simply by having light convert the photochromes to different isomeric forms. This document is subject to copyright.
