Ibrahimovic in talks over return to Old Trafford

first_imgHis rehabilitation has continued at the club’s Carrington training complex, with Jose Mourinho saying in July that he could resume at United despite Romelu Lukaku’s arrival. “Why not wait for such a good player that gave us so much?” he said.And with the latest news from Italy, it would seem United are stepping up their efforts to secure a return for the player who shone in his first season in the Premier League, scoring 28 goals in 46 appearances before injury struck.Ibrahimovic’s agent Mino Raiola told Sky in May there had been offers from “many leagues” for the former PSG and Barcelona striker and that he would “remain in Europe 100 per cent”, adding he still had “one more year, maybe two” left in his career.AC Milan have been the latest side to be interested in Ibrahimovic as they continue to overhaul their squad in a summer that has seen several Serie A sides make big statements in the transfer market.Atletico Madrid were also linked, while LA Galaxy president said their doors were “always open” for a player they had an “incredible relationship” with.Ibrahimovic would also be welcomed by his former team-mates. Paul Pogba said earlier in August: “He’s still a big leader because he’s still in the team, even he’s not playing he’s a leader outside of the pitch.”United get their Premier League season under way on Sunday when they host West Ham, live on Sky Sports Premier League.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Manchester United’s Zlatan Ibrahimovic pictured during the club’s Europa League quarter-final first leg against Anderlecht at the Constant Vanden Stock stadium in Brussels on April 13, 2017LONDON, United Kingdom, Aug 9 – Manchester United have started talks over a new deal to bring back striker Zlatan Ibrahimovic, according to Sky in Italy.The 35-year-old Swede is a free agent following his release from Old Trafford at the end of last season and is battling back to fitness after suffering a cruciate knee ligament injury in April.last_img read more

Darwinian Phylogenists Do the Funky Chicken

first_imgAfter all this reluctant criticism, Ronquist manages to find something to compliment, in closing:Although it is easy to criticize a book that tries to cover so much, in this case doing so is like throwing stones in a glass house.  Every phylogeneticist can probably find some points they understand better than Felsenstein, but I can think of no one who could provide a better and more comprehensive summary of the current methods for building evolutionary trees.  It will be a long time before there will be a comparable book; perhaps the field is now growing too fast for there to ever be one.  The publication of Inferring Phylogenies is a milestone for evolutionary biology in general and phylogenetics in particular.1Fredrick Ronquist, “Phylogenetics: A Broad Look at Tree-Building,” Science Volume 303, Number 5659, Issue of 6 Feb 2004, pp. 767-768.Sometimes you have to just stand back and let the Darwin Party members do it to each other.  Does anyone have confidence in evolutionary tree-building after this indecent exposure?  When an expert in the field omits significant parts of the story (why? because he feels they are invalid?), characterizes it as a battle over the most prestigious authorities, and describes one of the chief methodologies to be as mystical as casting chicken bones and using magical incantations, what are we supposed to conclude?  Don’t they realize it’s confusing to the peasants when the shamans are exorcising one another?For more on phylogenetic tree-building, see 11/26/2002 and 06/13/2003 entries, and follow the Chain Links on “Genes and DNA.”(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0 Fredrik Ronquist is active in phylogenetic systematics, the art of drawing evolutionary trees from DNA comparisons.  And he admires Joseph Felsenstein, an “icon in the field.”  But when he reviewed Felsenstein’s new book, Inferring Phylogenies (Sinauer, 2004) in the Feb. 5 issue of Science,1 he had mixed feelings about the author’s biases and his choice of humor.    Ronquist has much to praise about the iconic master’s work, concluding “I can think of no one who could provide a better and more comprehensive summary of the current methods for building evolutionary trees.”  Nevertheless, his criticisms are revealing about the state of this art:What is it about, anyway?  The book seems to omit a rather important part of phylogenetic systematics:What I found most surprising about the book is that it is not at all about systematics.  Readers will find no coverage of many basic concepts in phylogenetic systematics–such as synapomorphy, symplesiomorphy, sistergroups, outgroups, and monophyly.While Felsenstein covers many subjects like “techniques for statistical testing of evolutionary trees,” uses of phylogenies, and “nearly every quantitative approach to tree-building that has been tried,” Ronquist is most surprised there is no coverage of these important terms and concepts in a 684-page definitive treatise by an expert in the field.No help on classification.Another topic that many phylogenetic systematists consider important but the book glosses over is how one should convert phylogenetic trees into classifications of organisms.  According to Felsenstein, “The delimitation of higher taxa is no longer a major task of systematics, as the availability of estimates of the phylogeny removes the need to use these classifications.”  Even a cursory look at the literature would prove that many active systematists disagree; indeed, the discussion of classification and naming principles seems to be as vigorous as ever.  This neglect of the classification issue is all the more remarkable because Felsenstein devotes an entire chapter–one of the more original and important contributions in the book–to the drawing of trees (specifically, to algorithms for drawing diagrams of trees).  After all, drawing trees is just another way of communicating the results of a phylogenetic analysis.  Often a diagram is better, but sometimes a name is necessary.  I do not think we will ever see papers with titles like “The biology of .”Controversy is bitter.In a field that has been plagued by outrageously bitter controversy, the book is remarkably balanced on the whole.  For example, consider Felsenstein’s summary of the debates on statistical inconsistency.  It reveals when parsimony is inconsistent and suffers from “long-branch attraction,” but it makes no secret of the fact that likelihood methods can also be misled by similar phenomena when the model used for inference is incorrect.  The attempt to provide balanced coverage probably will not stop ardent parsimony advocates from being disappointed.This is because Ronquist feels Fenselstein was unfair in his choice of algorithms to exalt, and ones to ignore.The Bayesian Funky Chicken.  “The book’s coverage of Bayesian inference of phylogenies is surprisingly short and critical,” Ronquist complains.  Bayesian inference is a fancy mathematical form of educated guessing by applying values to likely causes, but it suffers from GIGO: garbage in, garbage out.  Ronquist disagrees with the author’s criticisms, and is not amused by the joking description Fenselstein gives to this technique as applied to evolutionary tree-building:I find the author’s complaints about prior distributions partly misdirected.  For instance, Mau and Newton’s prior on clocklike trees is described as “technically inadmissible” and “an impossible distribution” because it is an improper probability distribution.  But improper priors are often unproblematic in Bayesian inference, and there is an entire school of “objective Bayesians” who routinely use them.  The comment on the choice of proposal distributions is more funny than helpful: “At the moment the choice of a good proposal distribution involves the burning of incense, casting of chicken bones, use of magical incantations, and invoking the opinions of more prestigious colleagues.”last_img read more

Trade association leaders plead for Congress to Act on tax extenders

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Executives from 11 national trade associations sent a letter to House and Senate leaders, highlighting the urgent need for Congress to extend the expired biodiesel tax incentive before the end of the year.The association executives state in the letter, “There is broad bipartisan support for the biodiesel tax credit, and we believe that Congress can, and must, pass an immediate extension before returning home at the end of the year.”“America’s farmers and rural communities are facing overwhelming economic uncertainty right now due to policy instability. They are waiting for Washington to complete work on trade deals and stabilize markets for U.S. agricultural output in China, Canada and Mexico. The economic hardships are spreading throughout the economy,” the executives write.“One thing Congress can do before the end of the year to help rural economies and provide some policy stability is extend the expired biodiesel and renewable diesel tax incentive.”Made from an increasingly diverse mix of resources such as recycled cooking oil, soybean oil and animal fats, biodiesel is a renewable, clean-burning diesel replacement that can be used in existing diesel engines without modification. It is the nation’s first domestically produced, commercially available advanced biofuel. NBB is the U.S. trade association representing the entire biodiesel value chain, including producers, feedstock suppliers, and fuel distributors, as well as the U.S. renewable diesel industry.Kurt Kovarik, NBB’s VP of Federal Affairs, adds, “Biodiesel producers simply can’t wait any longer. Ten facilities have been shuttered this year, and more are on the verge of making that painful decision. More than 250 million gallons of production is now offline, idling hundreds of workers and impacting thousands of jobs. Our industry needs Congress to act before the end of the year to stop more shutdowns and job losses.”last_img read more

Designation Exhaustion

first_imgMany industries have designations and certifications available for practitioners, some of which have strong legal implications, such as MD and RN. Many others have been created by professions themselves, and, while requiring varying levels of rigor to attain, these are primarily marketing tools, proper usage of which is enforced by the industry or association.In the green building arena, we have seen a range of these titles emerge recently. One of the oldest and most prominent is LEED Accredited Professional (AP) . More recent entrants include the NAHB’s Certified Green Professional (CGP) and NARI’s Green Certified Professional (GCP). Other professional designations include Building Analyst Professional from the Building Performance Institute (BPI), Home Energy Rater (HERS) from Resnet, and Green Advantage Certification.Three green labelsI recently obtained my LEED AP Homes designation under the beta test of its new accreditation system. Starting later this year, people seeking LEED AP designation must take an expanded test that includes questions on their specific areas of expertise, rather than the general test that was available previously. Having taken and passed that test, I can honestly say that it was a disappointment. While it did address green building knowledge, fully half of the test was on commercial concepts, and many of the questions were literally a trivia contest requiring students to memorize arcane details such as how many points are available for a specific LEED credit. Qualified professionals should not have to submit to this kind of abuse—having to study minutiae that’s readily available with just a few minutes’ research to anyone with an elementary education.NAHB’s CGP designation (interestingly, even though “Certification” is in the name, it is referred to as a designation—curious wordplay, inspired by lawyers, no doubt) and can be obtained by taking a three-day class and passing a short test. I was involved in the creation of this training and have taught it many times. It is currently undergoing a much-needed update, which will bring it in line with the new National Green Building Standard, and, I hope, improve some of the less-effective parts of the training.During the development process, I argued strongly for a requiring builders to have completed buildings that were certified under a recognized green building program before they could achieve this designation, but that was left out of the final requirements. The biggest problem with this program is the inconsistent quality of instruction. I have heard from many attendees that their particular teacher did not have the depth of knowledge of green building to effectively present the material, diminishing the value of the class. I was recently informed that during the revision of this program, more stringent requirements for instructors will be implemented.NARI’s GCP designation requires professionals to self-certify that they have at least five years’ experience in remodeling, are currently employed by or own a remodeling firm, and have received a minimum of 16 hours green training in the last five years; they then must pass a test consisting of approximately 200 multiple-choice questions. There is an optional 24-hour study session that most candidates take advantage of. This program is offered nationally either through webinars or in-person through local NARI chapters.Three more, just for good measureHERS rater training involves five or more days of classroom and field training, followed by written and field tests. To become a certified HERS rater, one must obtain liability insurance and work under a “provider” organization that supervises the work and provides quality assurance on all their certified ratings. While this program is limited mostly to energy efficiency, it is among the most rigorous certifications available.BPI’s Building Analyst certification requires both a written and a field test, although the training is optional. Green Advantage is similar to BPI, requiring a test, with training being optional.Where do we go from here?So where does that leave our industry, or consumers, for that matter? Well, in reality, sort of nowhere. There are literally tens of thousands of people with LEED AP designations. NAHB’s CGP is coming on strong, with about 3,000 certified to date. There are a lot of HERS raters out there, and BPI and Green Advantage are plugging along, taking advantage (pardon the pun) of expanded interest in green building. LEED has definitely won the media race, although until very recently, its designations were exclusively commercial. While the actual value in this designation is questionable, the public awareness and added marketing value are tangible benefits of the program. It remains to be seen how much market presence the rest of the designations will command.I think we can all acknowledge that the primary value of a designation to industry professionals is marketing. A string of letters after your name can provide credibility and differentiation from the competition. I am very concerned that the wide range of requirements will add to marketplace confusion, not unlike what is currently happening with green-home certifications. Maybe one day we will see training and designations for professionals that are both comprehensive and have a strong market presence. Right now, however, we have one or the other, but not both.last_img read more

Isolating Image Channels to Work with Chroma and Luma in Premiere

first_imgMastering color correction means understanding the color channels that make a good image. Here’s how to isolate the chroma and luma channels in Premiere.I’ve covered noise reduction somewhat extensively over the past few months. In my article on manual noise reduction in Resolve, we took a look at the powerful results you can get from isolating the chroma and luma channels to apply noise reduction to each.Today, we’re going to learn how to isolate and work with image channels in Premiere — or any other similarly functional NLE. As with Resolve, there isn’t a plugin or button to quickly split your channels for you, so we’re going to do it manually.Before we start, what is the point of splitting the component channels?Each video clip is actually a blend of three distinct image channels. To put it simply, these component channels contain Luminance (or brightness and contrast) information, red color information, and blue color information. Baking these three channels into a single video stream enables much faster playback and simplicity of use.It is always good to know how to break down anything into its component parts, so without further ado, it’s time to split . . .Splitting Image ChannelsUnderexposed Donuts! The first step after you load your clip into a timeline is to duplicate the clip. In Premiere, the default quick keys for duplicating clips are alt+left click for windows and option+left click on mac.Separating LuminanceTo pull the chroma information out of our luma channel, all we need to do is navigate to the Basic Correction tab in the Lumetri color panel and slide the saturation to 0%.Separating Chroma ChannelsSeparating the chroma channels involves a few more steps. To start, duplicate your original (full-color) clip and place it above your luminance clip on the timeline. From here, navigate to the Curves tab in Lumetri and drag the top right point on all the curves (except for red) all the way to the bottom. Essentially, we’re cutting everything except for the red color in the shot.Duplicate the original clip once more, and place it on top of your red and luma clips. Now repeat the curves adjustments, but this time, isolate the blue channel.Now repeat the whole process once more for the green channel, placing it on top of everything.Technically, there isn’t a green color channel in the original clip, but I usually find the best results by including it. Test using or excluding it for your own clips.Now, go through each color layer and set its Opacity Blend mode to Lighten, but leave the opacity at 100%. (There are multiple blend modes and methods that will yield similar results, so experiment.)Your footage channels are now separated out by luminance and color, and you should finally have a normal-looking image again.Working with Split ChannelsNow, let’s look at a couple of things we can do to improve our donuts a little more.First, I’ll clean the timeline up a bit by nesting the three color channels. This is entirely optional, but I prefer previewing as few video layers as possible.One of the most useful reasons to separate luma from chroma is for sharpening your clip. Because the luma channel determines how we perceive sharpness, we can sharpen it individually from the color info, resulting in a clearer image without a lot of the nastiness that comes from sharpening footage in the color channels.But be careful not to go overboard — I’ve sharpened this clip by less than 20%.Cleaning up BlockinessOn the window to the left of the donut, we can see some severe artifacting caused by bringing the levels up on this shot. Let’s fix that.Select the chroma layer, and then head to the HSL/Secondary tab in Lumetri. Enable grey selection preview, and then find where the problematic blocking is by qualifying each channel.I’m fairly happy with my selection, so I’m just doing some basic tweaks to reduce its visibility.While we haven’t eliminated the blockiness entirely, we’ve pretty effectively covered it up. So let’s pull it out just a touch more.Chroma Channel Noise ReductionNow, we’ll apply Neat Video to the chroma layer and launch the plugin. I’ll do my best here to select this specific region of noise, despite Neat Video’s attempts to tell me that the region is too small. I usually shoot for 60% or greater selection quality, but here I was only able to get to about 45%, which should still work.Now move into the Noise Filter Settings to preview and tweak the results. With a bit of (uncharacteristic) luck, I think I’m good with the default filter settings. So, I’ll commit the changes and return to Premiere to ensure everything looks good there.I’ve tweaked the color on the results just a hair, and I think we’re looking great!Before.After.And that’s it! We have successfully split out our original footage into its component channels and brought the exposure to a much more appealing level while making the clip look even better than before.So try this method out if you’re having trouble salvaging your underexposed clips. There is so much more that you can do with your image channels separated — load up some clips, and see for yourself.Cover image via Simon Mayer.Looking for more articles on post-production?

Temple demolition: bandh by Dalit outfits hits life in Punjab

first_imgThe bandh call over the demolition of the Guru Ravidas temple in Delhi’s Tughlakabad village evoked a strong response in Punjab, even as members of Dalit outfits staged protests in many parts of the State on Tuesday.Most commercial establishments, shops and offices remained closed in Jalandhar, Gurdaspur, Hoshiarpur, Ludhiana, Fazilka, Barnala, Moga and Kapurthala. The bandh call was given by Dalits under the banner of the Guru Ravidas Jayanti Samaroh Samiti.Members of Dalit community were seen taking out marches and sitting on dharna at several places. Vehicular movement on National Highway 1 was disrupted in Jalandhar after protesters blocked the road as well as arterial roads. A holiday was declared for the educational institutions in Jalandhar, Hoshiarpur, Kapurthala, and Gurdaspur.Dalits, especially in the Doaba region of Punjab, have been staging protests ever since the temple was demolished on August 10 following a Supreme Court order over allegations of encroachment. Terming it an act of sacrilege, they are demanding the reconstruction of the temple on the same land where it stood.Punjab has a Dalit population of 32%, the highest in any State.last_img read more
