What causes a concussion? Stanford scientists search for clues

first_imgSTANFORD — Stanford researchers have made headway in understanding the causes of concussions that could lead to improvements in helmet design and onsite detection at sporting events.In a study published in Physical Review Letters the bioengineers found concussions and other mild head injuries seem to occur when an area deep in the brain shakes more rapidly and intensely than surrounding parts of the organ. “We are pinpointing the weak point in the brain during impact with the biomechanical …last_img read more

The Fabulous Prizes of SXSW: Free Phones, Plane Tickets, Vacations & Cars

first_imgHow do you get noticed at the jam-packed tech extravaganza that is this week’s South by Southwest Interactive event in Austin, Texas? How about giving away free cars and flights around the world? A number of startups in the location tech market appear to be trying to one-up each other with bigger and better give-aways at the event. It’s sure to make some people moan “tech bubble!” while other folks will just say “Yipeee! See you in Fiji!”Who’s giving away the most fabulous prizes? There will probably be many more contests unveiled over the next few days but here are three we’ve gotten pitches for already.Austin’s home town favorites Gowalla and AT&T are giving away more than 20 Samsung Captivate phones and Southwest Air is giving away 25 free roundtrip flights at check-in locations around town. (Look for the emblem above.) Gowalla just released a new version of its iPhone app this afternoon and will use SXSW to unveil a new feature called Gowalla Rewards. Location-based social networking competitor Foursquare, which blew up at least year’s SXSW, just unveiled a new local deals feature this morning as well. Short mobile video sharing service SocialCam, featherweight travel service AirBnB and flight search startup Hipmunk are giving away airfare and a week on a private island in Fiji to someone who records themselves doing something silly on SocialCam.Location check-in service Whrrl is giving away $125k in prizes to people who visit a variety of parties after signing up for its ironically named Austin Underground Society. Prizes will include 50 Las Vegas VIP packages, 20 copies of the Funny Or Die flick “Take This DVD and Shove It”, a ticket to and hotel for the Twitter 140conf in New York and two Audis!Location may be hot and SXSW may be a great place for startups, but it’s going to be a very crowded and noisy week. Maybe fabulous give-aways will help some startups stand above the crowd. It might seem a little crass, but you probably wouldn’t complain if you found yourself enjoying an island vacation in Fiji or driving a new car.Team ReadWriteWeb will be in Austin as well. We’ll be giving away free heart-felt handshakes to our favorite readers, commenters and friends. Especially any of you who would like to take us to Fiji with you.

Color Grading: Working with Hue vs. Curves in DaVinci Resolve

first_imgHue vs. LumThe Hue vs. Lum curve will affect the hue’s luminance. While powerful, say, for bringing a hue to life in an otherwise glum scene, it isn’t necessarily used often on 8-bit footage, or footage with a highly compressed codec. That’s because it will quickly bring out the artifacts. However, even with compressed footage, you can still slightly lighten hues to give them more attention without degrading the image.At first, it seems like the Hue vs. Sat and Hue vs. Lum curves are completely similar. In essence, I guess you could say they are. They both make a hue more or less visible. However, you have to remember that luminance accounts for how much black or white is mixed with the hue, while saturation indicates how much gray (or how pure the hue is).Increased saturation on the left; increased luminance on the right.So yes, while the goal of increasing a hue’s visibility will remain the same, the visual result will differ.The Hue vs. curves aren’t designed to completely overhaul the color schematics of your entire image; they are there to tweak and correct. The next time you feel like your image is great but is missing something and you can’t figure out what it is, take to the Hue vs. curves and see if a small tweak to one of the hues completes your image.Looking for more info on using DaVinci Resolve?

There are a few ways you can work with these curves. You can select the hue icons below the curve, which will create curve points at the corresponding hue position in the curve panel. In example image below, I’ve clicked the cyan icon, and it’s created a broad cyan control point on the curve, and by moving it up or down, the sea changes hue.This method is ok for when the hue change is a very broad adjustment. A better way of using the curves is to hover over the pixel range in the viewer, and left-click with the qualifier. This will then create a more defined curve point for precise manipulation.For example, if I’ve received instruction that the actor actually had a pink jacket on in the scene, and I need to correct it in the before shot, I’ll change the curves to Hue vs. Hue, hover over the yellow jacket, and left-click.When comparing the control points, you’ll see that when selecting the hue from the viewer itself, the control points on the curve become more defined.Now, within seconds, I can shift the yellow jacket to a new hue.This curve is great for smaller elements that need a subtle tweak, and you will find it’s much easier to get a better result than by using a qualification key, which can often be noisy. When comparing the Hue vs. Hue curve and the qualification key, you will see a more significant result using the curve. Of course, you can get the same result using the qualification key. However, it requires fine-tuning.Hue vs. SatThe Hue vs. Saturation curve allows you to change the saturation of any hue selectively. Although the Hue vs. Hue curve is arguably more powerful in regards to creative input, I find the Hue vs. Saturation curve the best curve for bringing an element in the image to life. Again, the curve works in the same manner as the Hue vs. Hue (they all work this way), and by moving over a hue within the preview monitor and clicking, I can then adjust the saturation in the curve panel with the newly added control points. Although there’s no visual indication, you increase the saturation of the hue by pushing the curve point up, or desaturate by pulling the curve point down.In the example image, while the paddle boarder is obviously noticeable as the only object in the composition, he doesn’t necessarily stand out. By increasing the saturation of his jacket, he immediately becomes more dominant in the frame.Conversely, if you felt like the paddle boarder was too visible, and the story required the character to be almost seamless with the composition, you could desaturate his yellow jacket. Note that this goes for all of the Hue vs. curves — you do not need to create a new node when selecting a different hue to manipulate. For example, if I wanted to saturate the yellow jacket and desaturate the ocean water, I could do so on one node on the same curve. Color wheels are certainly the primary grading tool in DaVinci Resolve, but that doesn’t mean you should ignore curves altogether.As an old school After Effects user, the RGB curves was my initial introduction to and primary method of color grading. Unless you had a third-party plug-in, RGB curves were the “advanced” method of color grading in After Effects around 2006-2007. Color panels and Lumetri came just after I had left the platform to become versed in DaVinci Resolve. I was excited to finally leave curves behind and jump into the color wheels, where the professionals seemingly spent all their time.Of course, there’s no denying that the color wheels are the primary grading foundation in Resolve. However, this is not to say that we should dismiss curves. In fact, with curves, especially the HSL curves, you will find a wholly new and advantageous set of tools.Let’s have a look at what the different operations will do.

Manuel Lanzini could make a comeback for West Ham

first_imgArgentine midfielder Manuel Lanzini is in the frame for a possible return to action for the first time in eight months.After being named in Argentina’s final 23-man squad for the 2018 World Cup in Russia, Lanzini had been preparing for the upcoming tournament when he sustained a ruptured anterior knee ligament injury in training in June.The 26-year-old has since spent the past eight months working hard on his recovery from injury and made a welcome return to training in January for West Ham.Now Hammers boss Manuel Pellegrini has revealed he may name Lanzini in the team to face 19th-place Fulham on Friday in a Premier League match.Samir Nasri, who signed for West Ham in the January transfer window after serving a drug ban, is also in contention to return after recovering from a small calf problem.“For this game we have the squad which played most of the games and maybe Lanzini and Nasri can be included on that squad list,” said Pellegrini on the club website.“They worked not only today but they worked the complete week. We will talk to the medical staff about whether we can use them.Harry Maguire, Manchester UnitedLiverpool legend Nicol slams Harry Maguire’s Man United form Andrew Smyth – September 14, 2019 Steve Nicol believes Harry Maguire has made some “horrendous mistakes” recently, and has failed to find his best form since joining Manchester United.“All four playmakers in our squad were injured, which is always difficult, so the return of both of them injects more quality into the squad.”Former Arsenal midfielder Jack Wilshere though continues to be a doubt with a new ankle problem and has made just five appearances for West Ham this season after arriving for free last summer.“We will analyse Jack Wilshere next week, then we will be more clear about his future,” added Pellegrini.Friday’s opponents Fulham are eight points adrift of safety in the Premier League table and have only managed one win in their last six league matches.“It’s a tricky game against a team fighting not to be relegated,” said Pellegrini.“They have a good manager and signed a lot of good players, so it will not be easy if we don’t play as we did against Liverpool and in the first 45 minutes against Crystal Palace.“We must start the game fast and play well with a good tempo to get the result that we want.”LONDON, ENGLAND – FEBRUARY 09: Mark Noble of West Ham United (3R) celebrates with teammates after scoring his team’s first goal during the Premier League match between Crystal Palace and West Ham United at Selhurst Park on February 9, 2019 in London, United Kingdom.
