Ohio State footballs Kerry Coombs Chris Ash and I are going to

OSU cornerbacks coach and special teams coordinator Kerry Coombs talks to the media on National Signing Day Feb. 5 at the Woody Hayes Athletic Center.Credit: Shelby Lum / Photo editorWith the introduction of Ohio State’s new co-defensive coordinator and safeties coach Chris Ash, some questions had to be answered.What is he going to do to fix a pass defense that finished 2013 ranked 112th in the country? How does he feel about the group of young players that will be playing next season?But perhaps the most important quandary is how cornerbacks coach and special teams coordinator Kerry Coombs and Ash will get along.“What I would tell you is that Chris and I are going to function as a team in the back end. We will have one voice,” Coombs told the media on National Signing Day Wednesday. “We both may be saying it, but we’ll be saying the same thing so that when we meet together, when we coach together, when we’re practicing together, we’re all using the same terms, the same phrases, the same words, coaching things and I don’t know, the same style. I haven’t been able to watch Chris coach, I don’t know his style yet, but (we’ll be) using all of the same language and verbiage out there. And I think that’s very important.”Coombs, who has been with the program for each of the last two seasons, added that there is not a rigid set of rules dictating who coaches what on any given day.“I believe very strongly that those things, the more you can do things in a group setting, the better off you’re going to be,” Coombs said. “And so our approach — Chris and I will work together to make that happen and there will be times when we will be working right half and left half. And at times, we’ll be working corners and safeties and at times we’ll be functioning with four guys doing things together … I would think they would tell you the same thing, that all of that will lead, I think, to great communication, which should be our objective moving forward.”Ash spent 2013 at Arkansas after spending three seasons with one of OSU’s Big Ten rivals, Wisconsin.Agreeing with his new coaching partner Coombs, Ash said coaching on the defensive side of the ball will be all about balancing everyone.“Everything we’re going to do is going to be a team effort,” Ash said. “You know a lot of people have asked about coach Coombs and I coaching the secondary. It’s going to be a team effort, and the defensive staff is a team, putting this package together. Trying to identify the direction we’re going to go and what we need to get fixed, and gameday, it’ll be a team effort.”At Wisconsin, Ash was a part of three consecutive Big Ten Championships and led a pass defense that finished an average of 16th in the country during his tenure.A big part of improving the Buckeyes’ struggles against the pass is changing the mentality, Ash said.“Well you play fast, you play with reckless abandon, you’re fast, you’re physical, you throw your body around,” Ash said. “There’s no confusion, you know exactly what you’re doing. You can react to your key and there’s only one speed: it’s full speed. And that’s the way we gotta play.”Coombs agreed, saying the intensity of play is likely to increase in 2014.“Yeah, I would think you would see a more aggressive style of play across the board from alignment to attack and so forth,” Coombs said.The secondary is only returning one regular starter in junior cornerback Doran Grant, and Coombs said it’s impossible to predict who is going to win the starting positions because players are battling for them.“There will be some changes. The competition I would tell you is wide open,” Coombs said. “You’ve got to perform to play. And I think that the expectation on the part of every player on this football team is you gotta show up every day and you’ve got to perform in order to play in the fall. We’re going to work really hard on finding those guys who can compete and who will challenge in tough situations.”Coach Urban Meyer said Wednesday the defense needed something new after struggling in the latter part of the season.“We won a lot of games, but there were some holes,” Meyer said. “Holes very easy to blame players or blames coaches. Just overall, we need to freshen up our defense. That’s what’s going to take place over the next few months.”Ash and Coombs are set to receive their first chance to patrol the Buckeye sidelines together Aug. 30 when OSU is scheduled to take on Navy at M&T Bank Stadium in Baltimore. read more

Football How offensive coordinator Kevin Wilsons offense at Indiana translates to Ohio

Credit: Nicholas McWilliams | Former Sports EditorIt is no secret that Ohio State’s offense over the past several years has been heavily scrutinized by the fanbase.Now that Ohio State has hired a new offensive coordinator, all eyes will be on Kevin Wilson in his debut season as he tries to appease those cries for an improved offense. But with Wilson leaving Indiana for Columbus, many are probably wondering how this new offense will look. QuarterbacksCalling the plays for redshirt senior J.T. Barrett, Wilson will be presented with a new style of quarterback to work with. Over his six seasons at the helm of the Hoosiers, Wilson has coached 15 different quarterbacks, who have amassed a total of 1,820 rushing yards. Barrett has 2,465 rushing yards in three seasons. While mobile quarterbacks have never been a major part of Wilson’s offensive arsenal at Indiana, his signal-callers have always seemed to find success in the passing game. Since 2011, Wilson’s offense has led the Big Ten in passing yards three of the six seasons (2012, 2013, 2015) and finished second in 2016. In four of Wilson’s six seasons at Indiana, the Hoosiers’ aerial attack tallied at least 3,000 yards, a feat the Buckeyes have accomplished only once in the Urban Meyer era (2014). Twice, that milestone was reached by just one quarterback (Richard Lagow with 3,362 in 2016; Nate Sudfeld with 3,573 in 2015), without the assistance of a backup quarterback. While Wilson will likely conform a little to Barrett’s game and coach a more mobile quarterback, his track record indicates that Barrett might be counted on for a little more production in the passing game. Wide ReceiversSince 2011 Wilson’s first season as a head coach, 80.6 percent of Indiana’s receiving yards have been tallied by wide receivers. With wideouts like now-Denver Broncos wide receiver Cody Latimer and now-Jacksonville Jaguars pass-catcher Shane Wynn, the Hoosiers had for several seasons one of the more potent receiving corps in the Big Ten. This provided their quarterbacks — including Sudfeld, who now plays for the Washington Redskins — plenty of opportunities to air it out.During Wilson’s tenure, wide receivers averaged 13.6 yards per catch. Wideouts totaled at least 2,600 receiving yards, twice surpassing the milestone of 3,000, in four of Wilson’s six years.In Meyer’s first five seasons at Ohio State, wideouts have only accounted for 69.7 percent of all receiving yards, and just 64.4 percent of all receptions.With a wide array of wide receiving options available next season, including redshirt junior Johnnie Dixon, sophomore Binjimen Victor, redshirt sophomore K.J. Hill and redshirt junior Terry McLaurin at his disposal, Wilson can be counted on to make the Buckeye wideouts more heavily involved than in past offensive schemes. Tight EndsThis season, Meyer and Wilson will feature four former four-star recruits at tight end, including trusted senior Marcus Baugh, who will have to shoulder much of the burden with redshirt sophomore A.J. Alexander out for the season with a knee injury. And Buckeye fans should expect to see Wilson target those tight ends frequently when his offense gets near the end zone. Though Indiana tight ends tallied only 9 percent of total receiving yards during Wilson’s tenure, they accounted for 15.2 percent of the program’s receiving touchdowns over the past six seasons. The biggest season for Hoosier tight ends came in 2015, when they were on the receiving end of 18.5 percent of the team’s passing touchdowns that season and 13 percent of all receptions. Wilson’s tendency to distribute the ball to his tight ends might turn around a trend of reduced tight end usage by the Buckeyes over the past two seasons. After a 2014 season when the position was heavily involved, accounting for 19 percent of all touchdown receptions and 11 percent of all total yards, Barrett has not been targeting tight ends over the past two seasons, as they have only caught 4.4 percent of passing touchdowns and 9.4 percent of receiving yards.Running BacksSince Wilson took over the Hoosiers, no position has been drafted as frequently as the running back position at Indiana, with Jordan Howard going in the fifth round of the 2016 draft and Tevin Coleman going in the third round of the 2015 draft. Despite the individual success of Howard and Coleman, a rush-based offense was never something Wilson ran on. Still, the Hoosiers twice finished in the top three for total rushing yards in the Big Ten (second place in 2015, third in 2014). However, the ground game for Indiana dropped off a bit in 2016 as it finished 11th in the conference with only 1,979 yards (3.7 yards per carry).Running backs have also not proven to be a featured part of the passing game at Indiana, like they have at Ohio State. The position accounted for only 15.8 percent of all receptions, 10.5 percent of all receiving yards and just 7.2 percent of receiving touchdowns over the past six seasons. Wilson’s reluctance to fully utilize the ground game stands in stark contrast to Meyer’s track record of keeping the backs busy in both the rushing and passing game. Since 2012, 16.3 percent of all receiving yards, 21.9 percent of all receptions and 12.0 percent of all touchdown catches have come from Meyer’s running backs.Part of the reason for this has been Meyer’s consistent inclusion of an H-back, with Curtis Samuel being the most prominent example of this role. Samuel led the Buckeyes with 865 receiving yards a season ago, and finished fourth in 2015. It awaits to be seen exactly how Wilson features the running backs in 2017 and beyond, but Meyer’s past track record of keeping running backs heavily involved could mean Wilson will need to work on utilizing them in his offensive schemes a little bit more than in past years. read more

UPDATED Good Samaritans Help Save Mackey Lake Plane Crash Survivor

first_imgCES Chief Roy Browning: “CES crews responded around 11am, and CES activated their dive team for response and put Nikiski dive team on standby. Nearby residents on the lake reported that the plane was sinking as crews were in route.”  Facebook0TwitterEmailPrintFriendly分享The pilot and sole occupant of a plane that crashed Tuesday into Mackey Lake, in Soldotna, survived with “minimal injuries” according to Central Emergency Services. A nearby good samaritan rode his boat out to the downed plane to assist the pilot. The Alaska State Troopers also responded to the scene, and it was confirmed that there was only one occupant onboard the plane at the time of the crash. According to Browning the plane was a Maule MX-7. The investigation into the cause of the crash has now been handed over to the troopers. The initial call to CES was that a plane had overturned upon landing in Mackey Lake. Browning: “Upon arrival by CES crews the pilot was able to get out of the plane with the assistance of local residents as they responded by kayak and were able to get him to shore to our ambulance crews.” last_img read more

Defects in 2D semiconductors could lead to multicolored lightemitting devices

first_img The researchers, led by Sefaattin Tongay, Joonki Suh, and J. Wu, at the University of California, Berkeley, the Chinese Academy of Sciences in Beijing, and MIT, have published their paper on the effects of point defects on 2D semiconductors in a recent issue of Nature’s Scientific Reports.”Typically, defects in materials are considered something not wanted,” Tongay told Phys.org. “On the contrary, most of the functionalities of the materials are enabled by various imperfections such as defects. In this work, we show that engineering the defects in two-dimensional materials allows us to create another light emission channel and also enhance the light emission. “This is likely to be a milestone in the field. We scientists did not know how to observe defects by optical methods, and here we have found the first signatures of defects in 2D semiconductors. That’s exciting. Apparently, defects are another way to tune/activate the material’s properties on-demand.”While the physics of point defects in 3D semiconductors has been widely studied, much less is known about point defects in the more recently developed 2D semiconductors. The low-dimensional electronic systems are highly susceptible to disorder and imperfections. In 2D semiconductors, this propensity is expected to strongly influence electronic and excitonic processes. One such type of newly emerging 2D semiconductor is monolayer transition metal dichalcogenides (TMDs). Because TMDs have direct band gaps, meaning electrons can directly emit photons, they are promising light-emitting materials. Here, the scientists found that removing chalcogen (sulfur) atoms from a 0.7-nm-thick sample of the TMD MoS2 significantly changes its optical properties. As the number of defects in the material increases, the overall brightness of the light that is emitted by the material increases. This light has a photoluminescence peak at 1.90 eV, which determines its wavelength and color. But the defects also created a new photoluminescence peak at 1.78 eV.

DOI: 10.1038/srep02657center_img Journal information: Nature The photoluminescence spectrum at 77K for pristine MoS2 and MoS2 with defects created by two different irradiation doses. The defects enhance the intensity of the original photoluminescence peak (X0) as well as create a new peak (XB). Credit: Tongay, et al. ©2013 Nature Scientists enhance light emission in 2D semiconductors by a factor of 100 The scientists found that this lower energy peak dominates the photoluminescence spectrum at low temperatures, and becomes weaker as the temperature increases until it completely disappears above 250 K (-23 °C). However, at room temperature, the presence of such defects enhances the light emission. This observation goes against the conventional wisdom in the new field of 2D semiconductors, which has been that optical emission intensity at room temperature is sufficient criteria for assessing the crystal quality of 2D semiconductors; the results here suggest that assessments of crystal quality should involve low-temperature photoluminescence measurements.The scientists also demonstrated that vacancy defects have similar effects on the optical properties of two other TMDs, MoSe2 and WSe2. These results indicate that the effects of point defects are likely universal in other 2D semiconductors, as well.The researchers propose that the underlying mechanism of these effects depends on the interaction of the defect sites with nitrogen gas in the air. In vacuum, the defects did not have any effect on the TMDs’ optical properties. The scientists explain that N2 molecules in the air may drain free electrons from the material at the defect sites, which results in a greater proportion of free excitons (electrons bound to holes) in the material. Some portion of the free excitons then get trapped and bound by the defect vacancies, forming bound excitons. Eventually, both free and bound excitons recombine radiatively and yield two distinct light emission peaks at 1.90 eV (~650 nm) and 1.78 eV (~700 nm), respectively. Since researchers can create these defects by irradiation or thermal annealing, the defect density—and the resulting changes in the material’s optical properties—can be controlled via defect engineering. This ability could lead to the production of 2D semiconductors with multiple bandgaps, multi-colored light-emission devices, and optical gas sensors, among other applications.”With a smart design, point-defective 2D semiconductors potentially show better materials performance, which can be realized by uncovering defect physics in 2D systems,” Suh said. “That’s our team’s ultimate goal!” When scientists remove individual atoms in a semiconductor material, the resulting vacancies become point defects. Contrary to what their name implies, these defects can have beneficial effects on the semiconductor’s properties and enable most functionalities of electronic materials. In a new study, researchers have demonstrated that point defects in 2D semiconductors result in an increase in the overall room-temperature photoluminescence intensity. Further, the defects create a new emission peak that could lead to a better understanding of defect physics in 2D semiconductors as well as future applications such as multi-colored light-emitting devices.last_img read more

Handicapped city

first_img23-year-old Abhinav Nagar set out to explore this Christmas charm a couple of years ago in and around St James’ Church in Kashmere Gate, known to be the oldest surviving church in Delhi. Accompanying him were his three friends, all students from the same college, nurturing generous dreams of a grand future full of accomplishments. Nagar remembers chatting amiably with his friends and enjoying the cool breeze and the Christmas air. But what happened next changed their lives forever. Also Read – Find your own happinessThere was total blackness as a cow darted in front of their vehicle, forcing Nagar to lose control of the car completely and crash into a nearby lamp-post on the pavement. He hit his spine instantly and his friends were injured too. Nagar woke up the next day in hospital. He could not move either of his legs and his doctor told him that he could never walk again. At 23, Abhinav became wheelchair-bound, overnight, and his life changed forever.This is not an isolated case of compulsive disability. There are hundreds and thousands of people all over the world witnessing their lives change all of a sudden due to a mishap, accident or some disease. But what we, the other half of the population who can walk, run, jump and enjoy life and every bit of it, do not realise is the pain these people experience everyday to walk that extra mile which once seemed impossible. Also Read – Into the wildThere are ambitions plans to turn Delhi into a smart city. But our national Capital is thoroughly devoid of a disabled-friendly infrastructure and basic sensitivity essential to make this place accessible to them too. There is a gross negativity prevailing for the differently-abled, who are always subjected to mercy of others for any kind of help or acceptance. It would thus be a great idea to create an infrastructure or give them an ambience that would not make it imperative for them to move around with someone else’s help or acceptance. A recently conducted study reveals that some of the city’s busiest places like Connaught Place, Lodhi Road, Sarai Kale Khan and Nehru Place are devoid of street infrastructure for the differently-abled and even for the elderly to navigate. These places are even inaccessible for those with reduced mobility, pregnant women, children, persons carrying luggage and those with temporary ailments. Some of the key problems found at Connaught Place were lack of proper signages and audio signals, non-continuity of tactile pavers and pelican crossings. Footpath height and width varied at many places and there was lack of kerb ramps and pedestrian crossings in front of busy bus terminuses like the ISBT, coupled with open drains on footpaths and encroachments by hawkers.Abha Khetarpal, president of NGO Cross the Hurdles says: “Essential services like banks, ATMs, post offices still remain inaccessible for the differently-abled. Even many of the doctors’ clinics and diagnostic centres are not disabled friendly. Schools do not have proper infrastructure to accommodate students with disabilities. Though public buildings, many stadiums might have ramps for wheelchair users to enter the premises but washrooms inside the campus are inaccessible. Personally speaking, I have found no washrooms for disabled people at Thyagraj stadium near INA market that was built as a venue for the 2010 Commonwealth Games.”She further elaborates: “Movie theatres again are not friendly. ‘Disabled friendly’ does not mean just a ramp being made outside the premises for wheelchair users. It must cater to the needs to all the different kind of disabilities. Tactile surfaces and Braille signage are rarely found. Many hotels and restaurants still remain unfriendly.”The differently-abled also face insensitive behaviour of bus drivers and conductors, who many a times charge more than the designated fare, despite travel for the visually impaired being free in all state-run Delhi Transport Corporation (DTC) buses and the National Capital Region (NCR). But statistics show that this is not restricted to Delhi or the NCR area alone. The 70 million disabled in India face similar problems in other parts of the country too and, possibly, things are much worse. Transportation in every Indian city and town has failed disabled citizens to live a smooth and uncomplicated life. Lack of awareness, contempt and lapsed policies contribute to their plight. Though low floor buses in several metropolises including Delhi are initiatives for making transportation smooth, it has hardly come as a boon.Javed Abidi, director, National Centre for Promotion of Employment for Disabled People in India mentions in a report: “Despite it being a norm, there are no ramps to get on to the bus stands in the national capital. It’s a shame that the DTC plays hoax on us by painting disabled-friendly pictures and signages at bus stops, as they never practice what they preach.” Unfortunately, there has been little done in this direction to address the issue.Khetarpal adds: “No railway station in Delhi has a lift. Though the bus stops show the universal symbol of disability has broken ramps or are just unreachable due the rugged surfaces or the large number of street vendors and hawkers.”Though many new pavements and sidewalks in most New Delhi Municipal Council and Municipal Corporation of Delhi (MCD) areas are spacious and well-laid, many of them are blocked by bollards or small iron posts through which a wheelchair can’t pass.According to disabled rights organisations, the special ramps constructed on many roads have faulty designs and do not follow international standards. Ideally, for a height of one metre the ramps should be 18 metres long (1:18 gradient). But the ramps are built on a 1:12 gradient and are steep. Moreover, they also do not provide a landing after every five metres. Even the parks in the national capital are not disabled-friendly. Summed together, there are as many as 14,000 parks in total but all of them more or less lie in a state of shambles and do not support visitors with disabilities. However, Mukesh Yadav, Public Relations Officer (PRO) of South MCD says: “Almost all our parks are disabled-friendly. All of them are at the ground level so there is particularly no need for a ramp. Also, there is one gate at the entrance of every park through which a wheelchair can easily enter.” But in reality, the story is a little different.Kanika Dua, an MA Psychology student in Delhi University who is partially visually impaired, says: ‘I’m very lucky that the crowd in my university is very good. People do help and try to understand our problems. Cops are very helpful. But when I go out of the campus, it is a little difficult as I don’t know all the roads, there are no Braille signages and mobility becomes an issue.’The Delhi Metro, often referred to as the lifeline of the national Capital, and rightly so, has stood the test of time in the last decade regarding performance. There is little doubt that the Metro has contributed in no small measure to taking Delhi and its infrastructural facilities to the next level! But this is just one side of the picture. Delhi Metro does seem ill-prepared not just for emergencies but also when it comes to helping the disabled with wheelchairs. The number of wheelchairs and stretchers at one of the busiest stations Rajiv Chowk, is limited to only three and five respectively!Shopping arcades and malls in Delhi are considerably better in terms of providing a friendly ambience for the disabled. Sonali Manilal, Marketing Head, DLF Promenade says: “The mall has reserved parking for physically challenged and senior citizens in B1. The parking has been reserved next to the elevator lobby with dedicated parking attendants. For physically challenged patrons, the mall is equipped with a dedicated and customized hydraulic elevator; all prominent entrances have wheel chairs stationed with an attendant; each shopping floor houses washrooms for the disabled.” In case of an emergency, she adds: “The staff is well trained in basic life saving skills and safety trainings. There is a medical room with bed and important medical equipment. The concierge is trained to use basic medical techniques and is always equipped with medical kit.” But for the past few years, there is a growing political momentum behind the need to take disability provision seriously.If available figures are to be believed, people with disabilities are more likely to be unemployed, illiterate, to have less formal education and less access to support networks. They are further isolated by discrimination, ignorance and prejudice. The World Bank estimates that about 20 per cent of the world’s poorest people are disabled. Poverty causes disability through inadequate access to medical treatment and vaccinations, and exposure to unsanitary and unsafe living and working conditions. Children with disabilities in India rarely progress beyond primary education, with school enrolment less than 10 per cent in many areas. This then reinforces social alienation and leads to very limited employment opportunities, leading to abject poverty. A universal barrier-free environment is every Indian’s dream. Reassuringly, a few have been lobbying for it for some time now, working towards creating and maintaining environments in which all people can participate in ways that are equitable, dignified, independent and safe for all. Obstacles of any kind affect the lives of people to a great extent, and it is not difficult to imagine the plight of millions of disabled people who face hurdles at every single step.last_img read more
