Researchers analyze performance of first updatable holographic 3D display

first_imgThese digital camera images show holograms created with the photorefractive polymer in an updatable holographic 3D display. Image credit: Christenson, et al. ©2010 IEEE. As the researchers explain, there is a big jump between developing static holograms, such as those that appear on credit cards and drivers’ licenses, and updatable holograms. A variety of materials can be used to make full-color, large-size static holograms, but none of these materials are updatable. As the researchers’ previous study showed, photorefractive polymers have the potential to offer colorful images and large sizes in an updatable display. The display they demonstrated was, at 4 in. x 4 in., the largest yet created. It could display new images every 3 minutes, and images could be viewed for several hours without the need for refreshing. With these features, the display could serve as the basis for future displays that could offer a variety of glasses-free 3D applications in medical, industrial, military, and entertainment imaging. “Photorefractive polymers are primarily beneficial because the method for achieving an index of refraction change is reversible and can be very fast, which is necessary for a real-world display,” coauthor Cory Christenson from the University of Arizona told PhysOrg.com. “Some materials currently used to make holograms are permanent and take hours to write. Additionally, the material permits making displays with large sizes (at least 4 in. x 4 in.), and in principle is scalable. Also, a single display device is stable for many months to a year or more before a noticeable drop in performance is observed. Photorefractive polymers are also attractive because modifying them with different polymers is relatively easy. If we want to test the effects of a different or new polymer to see if it helps increase speed or efficiency, it is not a significant challenge to make that composite.”Holograms, like photographs, are recordings of reflected light. Here, the researchers created a hologram based on a 3D model of an object on a computer, and no real physical object was required. They then generated 2D perspectives of the object on the computer, which were processed and combined to create about 120 holographic pixels, or “hogels.” To create a single hogel, the researchers modulated a laser beam with that hogel, focused the beam on a thin vertical line, and made the beam interfere with a second, unmodulated laser beam. The entire hologram could be written by repeating this process with all 120 hogels and positioning them next to each other. After all hogels were written, the researchers could illuminate the sample with a simple LED to make the 3D hologram viewable. The sensation of 3D is created due to parallax: each eye is seeing a different perspective of the object. Ideally, a polymer material should have a combination of a fast write-erase rate (required for video applications) and a high efficiency (required for bright images). Getting a high efficiency means adding traps for the charges generated, but traps also take time and slow down the write-erase rate, resulting in a tradeoff between these two features. In their study, the researchers tested two slightly different copolymers, each of which exceeded in one of the two areas. “In looking at both the standard display material composition and one that was slightly different, we were able to study the effects of adding more sensitizer and traps (in the form of C60) to the material,” Christenson said. “The greatest significance of this is a more in-depth understanding of the physics that leads to the formation of the hologram. This understanding gives us a better idea of its potential for use in new applications and will guide future studies as we attempt to improve the material.”The researchers determined that improvements could be made by mechanisms such as pulsed writing and reflection geometry, with the ultimate goal of creating realistic 3D holographic applications.“The primary area for improvement is the sensitivity of the material,” Christenson said. “The media for permanent holograms is more sensitive to light than these photorefractive polymers, which permit better looking holograms. We are trying to find ways of decreasing the light needed to write a hologram, which will make it much easier to expand into the areas mentioned in the paper, such as white-light viewing and writing at video rates.” Copyright 2010 PhysOrg.com.

NASA Roscosmos to discuss nuclear powered rocketry

first_img Explore further Russia hopes nuclear ship will fly humans to Mars Citation: NASA, Roscosmos to discuss nuclear powered rocketry (2011, April 6) retrieved 18 August 2019 from https://phys.org/news/2011-04-nasa-roscosmos-discuss-nuclear-powered.html Cooperation between the Russians and the United States in space exploration, is nothing new of course, dating back to the 1970’s and the Apollo-Soyuz missions, and more recently with astronauts from the U.S. and many other nations riding up to the space station on Russian rockets. What is new is the possibility of not just a rocket powered by nuclear energy, but a joint international project based on a technology that causes people from most any country to feel a little fear. The idea of a nuclear powered rocket exploding in the air shortly after takeoff (Challenger) or burning up upon reentry (Columbia) and spreading radioactive material over thousands of miles below is an issue that won’t go away any time soon.This would not be the first time that a spacecraft has employed the use of nuclear power (Soviet Topaz spy satellites, etc.) but it would be the first time an actual nuclear reactor would be installed onto a rocket and sent into space.Perminov, in his announcement, reiterated that Roscosmos has been working on nuclear powered rocket designs for quite some time and is now ready to move forward on developing an actual rocket, though there seems to be some discrepancies regarding the type of engine the agency has in mind. In earlier reports, it seemed the Russians were considering a reactor heat engine, but of late seem to be more of a mind to use the reactor to produce electricity to drive an ion or plasma type engine.The idea of using nuclear power to drive a rocket is not unique to the Russians, NASA and likely other space agencies have been working on their own designs for a nuclear powered rocket, as most in the field agree that chemical based engines just won’t work for long range space exploration. The sheer weight of the fuel along with the huge amount of cargo space required to hold it, prevent any serious thought of very long missions. Nuclear power on the other hand would require far less of both, plus it would require fewer moving parts.At this point, though not stated specifically, it appears the only thing holding back the Russians is the money to pay for their project, with current estimates at or near $600 million; and it’s the likely reason that the Russians are looking to form a consortium. Whether the United States or any of the other invited guests is willing to sign on to such a partnership though, is anyone’s guess. This document is subject to copyright.

62year old man makes car that runs on whisky

first_imgInventor Mickey Nilsson and his bourbon powered car (PhysOrg.com) — Mickey Nilsson, a 62 year old resident of Bardstown Kentucky, has found a way to turn his junk, into a car that runs on Kentucky Bourbon Whiskey. Nilsson, a long time tinkerer, got his inspiration from a character in the film Chitty Chitty Bang Bang. The character in question, one Caractacus Potts was best known for re-purposing junk to create new and more useful machines, which is exactly what Mr. Nilsson has done. Citation: 62-year old man makes car that runs on whisky (2011, April 25) retrieved 18 August 2019 from https://phys.org/news/2011-04-year-car-whisky.html The idea of doing something with an old still came to him last October, after he had some unusual visitors. The cast of a TV show, American Pickers, Mike Wolfe and Frank Fritz, came to try and purchase some of his items for the show. While they did manager to grab an older oil can from Mr. Nilsson, after making a disparaging crack about the use of his still, they were gently encouraged to leave his property, with the help of a fire arm. After a hasty retreat by the crew, Mr. Nilsson began to think about what he could do with that old still. After that, he spent six months in his workshop turning his pile of junk, still included, into a pretty snazzy looking car. According it is creator it will run on almost any bourbon created. Apparently, the engine prefers Maker’s Mark, though some people may find the cost, and the taste, of Maker’s Mark to be a deterrent from putting it into the car. This car has even attracted attention from the White House. President Obama released a statement saying, “the type of ingenuity that makes this country great. With brilliant minds such as Mr. Nilsson at work, we will soon purge our dependence on the middle east for oil”. A commercial version of this car may even come out in the near future. On Wednesday, Nilsson cut a deal with Nissan. who hope to release the vehicle to the public by 2014.

Research pair theorize metamaterials that exhibit negative compressibility transitions

first_img © 2012 Phys.Org Negative compressibility contrasted with other effects. Image (c) Nature Materials (2012) doi:10.1038/nmat3331 (Phys.org) — In the real world of so called “normal” materials, people expect certain things to occur as a result of certain actions. Covering an object with a cloak for example, should hide the object, but the cloak should still be visible (or vice-versa), or if you push or sit on a couch cushion, it should contract. Lately though, new science has been changing our perception of how materials should behave. For example, recent research into metamaterials; materials that aren’t normally found in nature, has been turning some of what we see as normal, on its head. The development of cloaking devices that hide objects and are themselves invisible, is one example. Explore further Improving on the amazing: Scientists seek new conductors for metamaterials More information: Mechanical metamaterials with negative compressibility transitions, Nature Materials (2012) doi:10.1038/nmat3331AbstractWhen tensioned, ordinary materials expand along the direction of the applied force. Here, we explore network concepts to design metamaterials exhibiting negative compressibility transitions, during which a material undergoes contraction when tensioned (or expansion when pressured). Continuous contraction of a material in the same direction of an applied tension, and in response to this tension, is inherently unstable. The conceptually similar effect we demonstrate can be achieved, however, through destabilizations of (meta)stable equilibria of the constituents. These destabilizations give rise to a stress-induced solid–solid phase transition associated with a twisted hysteresis curve for the stress–strain relationship. The strain-driven counterpart of negative compressibility transitions is a force amplification phenomenon, where an increase in deformation induces a discontinuous increase in response force. We suggest that the proposed materials could be useful for the design of actuators, force amplifiers, micromechanical controls, and protective devices.Press releasecenter_img Journal information: Nature Materials Citation: Research pair theorize metamaterials that exhibit negative compressibility transitions (2012, May 23) retrieved 18 August 2019 from https://phys.org/news/2012-05-pair-theorize-metamaterials-negative-compressibility.html Now, two researchers Zachary Nicolaou and Adilson Motter, from Northwestern University have proposed another material that doesn’t behave the way we’ve come to expect. They are proposing a metamaterial that reacts contrary to the expected norm, to pressure. When pushed on, it expands, when pulled, it contracts. The two have written a paper describing how such a matermaterial could be made and have had it published in the journal Nature Materials.While such a material might seem contrary to the laws of nature, the two explain how a metamaterial could be made that actually exploits such laws, rather than changes them. They suggest that if a material were constructed out of a row of four, as yet undetermined elements, where each was made of groups of molecules that are attracted to one another, then, if a force was applied to the inner particles that would be weak enough such that pulling on the metamaterial would cause those bonds to break, then the outer particles would become more strongly attracted to one another, causing compression. If on the other hand the material is squeezed, the inner particles would be brought closer together strengthening those bonds, causing the material to expand.The two have not yet made an actual metamaterial that exhibits such behavior, but it’s not difficult to see how it could be put to practical use if real ones are constructed; in fact, it’s not a far cry from the properties of the shield Captain America uses to ward off violent attacks. Military vehicles with such a material could expand out when driving over an IED, for example, preventing injury to occupants or car cushions could be fashioned creating perhaps, the smoothest ride ever.

Researchers find link between amount of silica in subduction zones and frequency

first_img Scientists have only known about slow earthquakes for a few years—since they can’t be felt, there was no real indication that they were occurring. They happen when silica rich sediment is pushed from below when one plate pushes beneath another. The fluid is trapped causing pressure to build—eventually that pressure is released by slow sliding (due to lubrication provided by the silica), rather than the jolt associated with surface quakes. After the sliding stops, the pressure begins to build up again and the whole process is repeated. Such quakes can occur over days or even weeks, releasing energy equivalent to large surface quakes. Scientists now know that such quakes occur off the coast of Japan, New Zealand, the United States and Canada, but, they all have a different frequency rate. They happen every two years in New Zealand, every six months in Japan and every 14 months beneath Canada’s Vancouver Island. The difference in rates, the researchers have found, is due to the amount of silica in the fluid—there more there is, the faster faults knit together after the sliding has stopped.The pair of researchers note that much more study needs to be done before it can be determined if slow earthquakes can be used to help predict surface quakes. In their experiments, they found the crust to be 5 to 15 percent quartz above the plates in the Cascadia subduction zone, an area that experienced a magnitude 9 quake in 1700. Scientists believe a major quake will likely occur again there sometime over the next 200 years. If slow earthquakes are found to portend larger ones, perhaps enough warning time can be given to save lives in the heavily populated area. (Phys.org) —A pair of researchers, Pascal Audet and Roland Burgmann of the Universities of Ottawa and California, respectively, has found a connection between the amount of silica rich quartz above subduction zones and the frequency rate of “slow” earthquakes. In their paper published in the journal Nature, the two describe how they measured quartz amounts in the Cascadia subduction zone using seismic waves, and how it relates to slow earthquakes.

In Cascadia, slow slip is segmented along strike and tremor data show a gradation from large, infrequent slip episodes to small, frequent slip events with increasing depth of the plate interface. Observations and models of slow slip and tremor require the presence of near-lithostatic pore-fluid pressures in slow-earthquake source regions; however, direct evidence of factors controlling the variability in recurrence times is elusive. Here we compile seismic data from subduction zone forearcs exhibiting recurring slow earthquakes and show that the average ratio of compressional (P)-wave velocity to shear (S)-wave velocity (vP/vS) of the overlying forearc crust ranges between 1.6 and 2.0 and is linearly related to the average recurrence time of slow earthquakes. In northern Cascadia, forearc vP/vS values decrease with increasing depth of the plate interface and with decreasing tremor-episode recurrence intervals. Low vP/vS values require a large addition of quartz in a mostly mafic forearc environment. We propose that silica enrichment varying from 5 per cent to 15 per cent by volume from slab-derived fluids and upward mineralization in quartz veins can explain the range of observed vP/vS values as well as the downdip decrease in vP/vS. The solubility of silica depends on temperature, and deposition prevails near the base of the forearc crust. We further propose that the strong temperature dependence of healing and permeability reduction in silica-rich fault gouge via dissolution–precipitation creep can explain the reduction in tremor recurrence time with progressive silica enrichment. Lower gouge permeability at higher temperatures leads to faster fluid overpressure development and low effective fault-normal stress, and therefore shorter recurrence times. Our results also agree with numerical models of slip stabilization under fault zone dilatancy strengthening15 caused by decreasing fluid pressure as pore space increases. This implies that temperature-dependent silica deposition, permeability reduction and fluid overpressure development control dilatancy and slow-earthquake behaviour.

Pedestrians at crosswalks found to follow the Levy walk process

first_img Journal information: Journal of the Royal Society Interface When large groups of people stand on either side of a road waiting for the light to change and then find themselves walking toward one another, they tend to walk in predictable ways. The approach taken is not generally one that typically provides the most direct or the quickest route, but one that takes into account the other people around them. In this new effort, the researchers sought to learn more about the behavior of people in such situations by studying them very closely in action.To learn more about how people behave in crosswalk-type situations, the researchers enlisted the assistance of volunteers and asked them to walk in what they describe as mock corridors. As the volunteers did so, the researchers filmed them in action. They noted directional changes, the number of steps taken and step patterns.The researchers found that individuals tended to deviate from their expected straight-ahead path as a means of most efficiently reaching their destination, and in so doing, faced a trade-off between path length and speed of transit. They noted that each individual made adjustments to their path based on the actions of those traveling in the same and opposite directions. They also found that collective action tended to arise, though the individuals involved did not seek to become participants. The collective action typically involved the formation of streams of people walking in uniform ways in both directions. Thus, rather than people continually meeting face to face, walkers would simply follow a person moving in the same direction, preventing the constant need to shift their path. Doing so increased efficiency both for the individuals and for the crowd as a whole. The researchers also found that streams created by walking individuals followed the Lévy walk process.The Lévy walk process is a mathematical description of a type of walk in which the pedestrian takes small steps, but then takes long steps at regular intervals. Mathematician Paul Lévy showed that it leads to a power-law distribution of step lengths.

Donation worth flaunting

first_imgIn the 65 years since its inception, National Museum (NM) for the first time, is hosting an exhibition of a treasure-trove donated by a private individual. Close to a 100 works which C L Bharany and his father collected from across India will be displayed for over a month in a specially designed gallery. Sculptures in stone, bronze, and wood, besides paintings (on paper and cloth), manuscripts and textiles across the past two millennia will be showcased at the month-long show, titled A Passionate Eye. Also Read – ‘Playing Jojo was emotionally exhausting’The exhibition, mounted on 6,000 sq ft carpeted space, brings out select items from a donation of close to a thousand objects Bharany made to the museum in 1976 in memory of his father. ‘It thus acknowledges one of many people who have helped gather items of our cultural heritage,’ says Venu V, Director-General of National Museum. ‘It highlights the role private collectors have played in enriching the nation’s public museums.’Giles Tillotson, one of the curators of the exhibition, notes the Bharanys – starting from Radha Krishna, the late father of Chote Lal (now 87) — are among the most significant collectors of Indian art in the 20th century. ‘What is striking is not just the range and quality of the works they assembled; their contributions to the work of scholars and of the country’s museums are immense,’ he says. Also Read – Leslie doing new comedy special with NetflixThe objects at the show are diverse in terms of social context as well, ranging from courtly art and elite items to rural and folk art. ‘Indeed Bharany’s breadth of vision is a notable feature of his collecting: irrespective of where and when works were made, and for whom, his eye alights on anything of beauty,’ says curator Venkateswaran. Through its design, the exhibition seeks to reflect this variety and eclecticism. Objects are grouped sometimes by material such as textile and sometimes by subject matter or themes such as asceticism – irrespective of provenance and date – to highlight the varied and layered links that inspire collecting. Venu says National Museum is keen to share more of the collections with people, and similar exhibitions will allow visitors to show more than what is on permanent display. ‘This is the first special exhibition National Museum is holding to explore this subject,’ he adds.last_img read more

Govt to install special devices across city to reduce pollution says Adhikari

first_imgKolkata: State Environment minister Suvendu Adhikari on Wednesday said the government is going to install special devices across the city that are enabled to suck dust particles thereby reducing pollution.During a meeting on air quality in and around Kolkata with renowned construction companies, civic bodies and police, several issues were raised and guidelines were given. Adhikari maintained that the pollution level increases as the Particulate Matter (PM) 10 and PM 2.5, which are commonly known as dust particles, go up in the air. The Nitrogen Dioxide (NO2) also hampers the air quality. To deal with such problems, the construction companies have been asked to cover the area where construction is on and also spread water in and around the area for stabilisation of the dust particles. Also Read – 3 injured, flight, train services hit as rains lash BengalIn Wednesday’s meeting, the civic bodies were asked to keep vigil in their areas to prevent actions polluting the environment. The minister also informed that many people are facing lung ailments due to pollution. Just after the meeting was over, he mentioned that several eminent and aged persons have died recently, who might have survived for a few more years if the pollution level was under control. During Wednesday’s meeting, there were no representatives from Rail Vikash Nigam Limited (RVNL). Regarding this Adhikari said: “We are taking strong note of it. They will be asked to provide a reason for not being present at the meeting.” At the press conference, the minister said the air quality has improved. But the use of some components that are polluting the environment needs to be controlled. “I am urging people not to worry. We are going to check the elements in the air and bring down pollution,” Adhikari added.

Global suicide rate falls by 33 per cent

first_imgThe rate of deaths from suicide worldwide has decreased by almost a third since 1990, according to a study published Thursday which also found that over 44.2 per cent of those who took their own lives in 2016 were from India and China. The study published by The BMJ journal found that total number of deaths from suicide increased by 6.7 per cent globally between 1990 and 2016 to 817,000 deaths in 2016. However, when adjusted for age, the global mortality rate from suicide decreased by almost 33 per cent worldwide over the same period. Researchers from University of Washington in the US show that men had higher mortality rates from suicide than women, and that higher rates tended to be linked to higher levels of social and economic deprivation. Also Read – Add new books to your shelfHowever, the research also showed that suicide trends vary substantially across countries and between groups, reflecting a complex interplay of factors that warrant further investigation. Deaths from suicides in China and India-as the most populous countries-together constituted 44.2 per cent of global suicide deaths in 2016. Suicide is a global public health concern, with around 800,000 deaths reported annually. The World Health Organisation aims to reduce suicide mortality by one third between 2015 and 2030. Also Read – Over 2 hours screen time daily will make your kids impulsiveIdentifying those most at risk is therefore crucial for national prevention efforts, researcher said. They used data from the 2016 Global Burden of Disease Study to describe patterns of suicide mortality and years of life lost globally and regionally, and by age, sex and sociodemographic index (a combined measure of fertility, income, and education) from 1990 to 2016. Suicide was the leading cause of age standardised years of life lost in the high income Asia Pacific region and was among the top 10 leading causes of death across eastern Europe, central Europe, high income Asia Pacific, Australasia, and high income North America. Globally, suicide rates were higher for men (15.6 deaths per 100,000) than for women (7 deaths per 100,000). However, the rate of decrease was lower for men (24 per cent) than for women (49 per cent). Women also experienced higher rates than men in most countries with a low sociodemographic index. Suicide continues to be an important cause of mortality in most countries worldwide, but it is promising that both the global age standardised mortality rate and years of life lost rate from suicide have decreased by a third between 1990 and 2016, researchers said.Whether this decline is due to suicide prevention activities, or whether it reflects general improvements to population health, warrants further research, they said.last_img read more

Holi When fun ends care begins

first_imgUndoubtedly Holi is the most awaited festival in India, which brings a lot of enthusiasm for people of all ages. But, at the same time, it also invites an unavoidable hassle of getting rid of the colours used while playing Holi.Taking this grave problem into consideration, experts list down easy ways to deal with the ‘post-Holi’ struggle: Certain precautions are always advised to be taken before you jump into the splash of colours, but Neeleshwari Basak, Owner of WorldWide institute of Grooming and Peagents, says that it is very crucial to realise the importance of post-festive skin care too. She believes that Holi is a festival in which it is necessary to work more after the celebrations, than in the preparation phase. Also Read – Add new books to your shelfRather than scrubbing off the colour with soap, the beauty expert suggests to use a mild cleanser on the skin, followed by applying a light moisturising cream. Listing some natural ways, she tells that one can even make a face pack using two tablespoons of calamine powder, and mixing it with a few drops of honey and rose water. “Apply it on the face and leave it till it dries. Afterward, wash it with cold water and apply a moisturiser,” she recommends. Also Read – Over 2 hours screen time daily will make your kids impulsiveObviously if you did not have your hair covered, you would need hair tips too. Basak suggests to properly rinse your hair with luke warm water. Make a simple hair pack by soaking a few fenugreek seeds in four tablespoons of curd. Apply this pack on your scalp and leave it for 30 minutes. For deep conditioning, you can also apply a mixture of honey and olive oil. After that, just wash the hair with a good shampoo. Shikhee Agrawal, Head- Training, The Body Shop India, also lists some tips and tricks: She suggests that one should just rinse their face with plain cold water at first, and then apply a cleansing cream or a face lotion all over it. This would help in deep cleaning the pores of your skin. It is very important that all the impurity and toxic substances release out of your skin pores. So it is advisable to use a cleanser containing less of chemical elements and more of natural ingredients like Tea Tree. “After a full day exposure to the sun and harmful hues and toxic elements flying in the air all throughout the day, our eyes become really stressful. Apply good and efficient eye cream full of vitamin E before dozing off to sleep. This will make you feel fresh next morning, and will also clear your dark circles overnight,” she states.last_img read more

NIck Wright If Cleveland wins tonight they win the series

first_imgTonight, the Warriors get their emotional leader, physical presence, and primary crotch hunter, Draymond Green back. The usually efficient Golden State Warriors’ were out of synch, and ineffective when he was suspended for Game 5. Green will return tonight under the microscope of the league and fans. The biggest question is; can he control himself?Nick Wright filled in for Colin today, and thinks the best strategy for the Cavs tonight is to bait Green into another flagrant foul so he’ll miss Game 7.“I don’t think he can control himself, I think it’s totally in play that he does something that will get him suspended for Game 7.  Coming off the near suspension against OKC, he was awful.”The Warriors will need the aggressive and agitating Green to win in Cleveland. If he’s less aggressive because he’s concerned with getting hit with another flagrant, the Warriors could be in trouble. The game after he avoided suspension from kicking Steven Adams, Green had his worst performance of the Playoffs. Advertisement In terms of pressure, Game 6 is going to feel a lot like a Game 7. Another Cavs’ win shifts the pressure squarely to the Warriors. Nick made a bold prediction if the Cavs are able to win tonight.“If the Cavs win tonight they win the series.”last_img read more

Colins NFL Week 10 Blazin 5

first_img5. Cowboys (+3) at Falcons – No Zeke this week, but Colin still likes Dallas getting 3 on the road in Atlanta. The Falcons are 0-5 ATS over their last 5, and are 1-4 in their last 5 overall. Atlanta is 1-4 when allowing 100+ rushing yards on the year, and will face a Cowboys offense averaging 183.4 Rush YPG over their last 5. Even without Elliott, they should still be able to run it effectively behind their dominant-line with Alfred Morris and Rod Smith platooning.The Cowboys defense has traveled well this season. In 3 road games, they’ve allowed just 15.3 PPG and 302.3 YPG. As a team, Dallas has a +55-point differential in their last 3 away from home.Zeke, or no Zeke, take Dallas and the points over the inconsistent Falcons. 34-26, Cowboys.? Blazin’ 5 is 27-18 through Week 9 ?@ColinCowherd makes his Week 10 picks? and they’re ? pic.twitter.com/TaRNSSq1ma— Herd w/Colin Cowherd (@TheHerd) November 10, 2017 Advertisement It’s NFL Week 10 and time for Colin’s Blazin’ 5 NFL picks. Colin had a small setback with a 2-3 week last week, but he’s still 27-18 on the year (60.0%), and he loves this week’s slate of games, including what might be his favorite pick of the year.Back up the Brinks truck. Here are Colin’s Week 10 NFL plays:Vikings (-1) at Redskins – Colin likes Minnesota and their dominant defense, coming off a bye, going on the road to D.C. The Vikings are 4-2 ATS over their last 6 facing a Washington team that’s just 1-4 ATS in their last 5, and 1-5 ATS over their last 6 at home. Washington hasn’t exceeded 300 yards of total offense in each of the last 2 weeks and likely won’t start this week against a Minnesota D that hasn’t allowed 300 yards to an opponent since Week 3.During their 4-game win streak, the Vikings are averaging 32.5 rushing attempts, 132.0 yards per game, and have a rushing touchdown in each game. They should be able to manufacture enough points against a Redskin defense that’s allowing 24.3 PPG. Take the Vikings, lay the 1. 24-20 Minnesota. 2. Chargers (+4) at Jags – Colin is rolling with the Chargers getting 4 on the road in Jacksonville. L.A. is 12-5-1 over their last 18 on the road, and their only loss in the last month was a one-score loss to on the road at New England.  The Jags are 1-2 at home on the year, and averaging just 18.7 points per game. In their last 9 home games overall, they’re only 3-6 ATS. In their last 5 against the Chargers, they’re 0-5 ATS.Joey Bosa and the L.A. pass rush, ranked 4th in the NFL in sacks (26), should be able to harass Blake Bortles, who has the 2nd worst passer rating (60.3) against the blitz in the league.Take the Chargers, the points, and the outright upset. 26-20, Bolts. 4. Saints at Bills (+2.5) – The Saints have been one of the surprise teams in the NFL, but Colin likes Buffalo getting points at home this week. It might be his favorite pick of the year. Buffalo has been tough at home all year, and this game is crucial if they’re going to contend for a playoff spot because they face New England, K.C., and the Rams on the road the next month.The Saints are averaging over 140 yards rushing during their 6-game winning streak, but it’s unlikely they’ll come close to that against a tough Bills D that ranks 8th against the run, and 5th in scoring defense, at home. The Saints also have a young roster, which could be a factor.The Bills circle the wagons in a must win. Take the 2.5 and the outright win.  26-22, Buffalo. 3. Jets at Bucs (+2.5) – Colin likes the Bucs as a 2.5-point home dog against the upstart Jets. The Jets have been a nice story, but they’re bad on the road. They have 7 turnovers and are allowing 398.5 yards per game to opponents in their four road games, this year.Jameis Winston is out, but back up Ryan Fitzpatrick has a 95.7 passer rating, and is completing 62.5% of his passes in limited action.Take Tampa and the points at home. 28-23, Bucs.last_img read more
