Romelu Lukaku revealed that Manchester United players are enjoying the happy atmosphere in training since the exit of Jose Mourinho.The Belgian forward may not be having more game time under Ole Gunnar Solskjaer, but he admitted the positive vibes in the squad has been a key factor to their success.“It’s different, a lot more positive,” he told Canal+.“People are smiling. At the moment everything is going well, and we have to continue like this. We’re enjoying it.”Lukaku further claimed everyone is getting back to their best again after a difficult start to the campaign, with the improved form of Pogba and Rashford a testimony to the assertion.“We tell him at training, Paul is happy, and then he laughs,” Lukaku disclosed via FourFourTwo.Chelsea hat-trick hero Tammy Abraham hopes for more Andrew Smyth – September 14, 2019 Tammy Abraham hopes this season will be his big breakthrough at Chelsea after firing his first hat-trick for the club in Saturday’s 5-2 win at Wolves.“At the moment, everyone is playing at their level. That’s what’s good. Paul, Marcus (Rashford), even myself when I play, I try to bring something to the team, Anthony (Martial). The competitive mindset is returning in every player.“You see it at training when we do mini games, 6 vs 6, 8 vs 8, you can see the players are wanting to prove themselves to the manager because they want to take their chance, but the most important remains the team. That’s what’s going to help us to return where we belong.”Up next for Manchester United is a tricky tie against relegation-threatened Fulham on Saturday.Lukaku: “This competitive spirit is coming back out of each player, it has already started in training when we play small-sided matches, 6 vs 6, 8 vs 8, you can see it the players want to prove themselves to the manager.” #MUFC #GGMU pic.twitter.com/74u1IXB7Jp— UnitedReds.com (@UnitedRedscom) February 4, 2019
I love Google. I believe it to be one of the greatest American businesses ever launched. For the last dozen years, I have been a partner as well as competitor to Google. I have seen firsthand the incredible breadth of engineering talent and resources they bring to the market. As a publisher, I was a long-time customer of syndicated Google search advertising as well as embedded, contextual text advertising.Google is brilliant at serving and monetizing text advertising. Whether done on the search result page or via contextual mapping to page level content into a dedicated module, these are solutions that no publisher can directly offer. These are solutions based on mapping scale of advertisers to scale of potential keywords, something no individual publisher can possibly replicate. The money generated from these placements is incremental and does not compete with the publishers’ own direct efforts to sell a similar product.Display is a different ballgame. A premium publisher’s core business is in selling a high-value display placement into their curated environment at a premium price. While programmatic buying is surely challenging the value of this model, it still represents a significant market with hundreds of top-tier brand marketers placing value on the age-old premise of the right ad delivered to the right individual in the right environment. Google’s core display product undercuts this model in damaging ways. Google will serve what its algorithm perceives to be the best possible ad at that given moment. It does not discern the appropriateness of the ad content itself or the economics involved. This often defaults to the lowest common denominator served into a premium display position—a text ad, from a direct response marketer, sold for less than 10 percent of what the publishers’ direct sales force is trying (and succeeding ) to get for that same inventory.This is particularly damaging in emerging areas like mobile. Because most premium publishers don’t sell their mobile inventory yet, you often see Google text ads appearing in prime display mobile real estate. Because many of these publishers are using DFP as their first party ad server, Google wisely makes it very easy for them to automate their Adsense backfill.Here is the prime example. This is a screen shot of The New York Times mobile home page from a few months back. The NYT has not sold this position so it defaults to a backfill solution from Google. This is what served: Now I’m an old digital guy and still view the home page of the NYT as a very premium buy. I see top 50 brands paying top dollar to get that position. Google has done a great service to the Counseling Anxiety in Miami advertiser. I wonder if they even know they owned the homepage of the NYT. For the NYT, this is a horrible result. Never mind the poor quality of the ad content and how that sullies the environment for the reader; I’m not sure how their sales team can go to market selling the exclusivity of the placement to their top-brand advertising partners when this is what’s running there.So what can you do if you’re a premium publisher with lots of unsold inventory?1. Put the right resources in place to sell it yourself, and in the way it needs to be sold—as a high-value, high-impact display unit.2. Work with specialist networks that focus on premium inventory and premium brands.3. If you’re going to backfill, do it via an SSP (Pubmatic, Rubicon, or even AdMeld, which Google owns), where more competition for the inventory should produce better ads and better economics.4. If you’re going to just run Google ads, then have somebody at the switch watching to make sure there are minimum standards of ad content quality and yield.Don’t get me wrong; Google is a great and critical partner to the publisher and would be the first to point out they give the publisher control to manage their inventory. The reality is that most publishers don’t have the resources to do this, so they default to something that in the long run undermines their business. Be smart. Protect the premium value of your brand and inventory.
This illustration shows the ExoMars rover on Mars. ESA Next year was shaping up to be a big one for Mars rovers. NASA is aiming to launch its Mars 2020 rover and the European Space Agency is also planning to send off its own ExoMars rover. But the ESA’s schedule might be in jeopardy after a series of parachute testing failures. ESA shared the news Monday of an “unsuccessful high-altitude drop test.” The rover, named Rosalind Franklin for the DNA pioneer, is meant to be gently lowered down to Mars with the help of two main parachutes attached to a descent module. Enlarge ImageThis graphic shows the parachute deployment sequence for ExoMars. ESA Those two parachutes each have a smaller pilot chute that helps deploy the bigger chutes, one of which would be the largest ever flown on a Mars mission with a diameter of 115 feet (35 meters). That parachute passed a low-altitude drop test in 2018, but a high-altitude drop test for all four parachutes in May didn’t work out as planned.The deployment mechanisms worked properly for the May test, but the main parachute canopies were damaged in the process, ESA said. The space agency tweaked the parachute design and tried again last week, but once again the parachute canopy suffered damage. The test module descended from a high-altitude helium balloon down to Earth with just the drag of a small pilot chute to slow it down.ExoMars team leader Francois Soto described the test failure as “disappointing.” Mars parachute experts from ESA and NASA will help troubleshoot the issue. Dying space missions remembered in inspiring final images ESA Mars rover named after Rosalind Franklin, brilliant DNA pioneer Scientists finally know where they’re sending the new Mars Rover Share your voice Post a comment Rover fever 14 Photos 0 Mars rovers Space Sci-Tech Space missions are notorious for delays and ESA will need to sort out the parachutes very quickly if it hopes to stay on track to launch the rover in mid-2020. ESA is already planning a new main parachute test before the end of the year. ExoMars is a joint effort between ESA and Roscosmos. The rover is designed to drill into Mars and analyze the soil in search of evidence of life on the dusty planet.The rover itself is on track for completion soon, but the landing systems will need to work flawlessly before they’re given the green light to go all the way to the red planet.

Logos of Tata Consultancy Services (TCS) are displayed at the venue of the annual general meeting of the software services provider in Mumbai, June 29, 2012.ReutersTata Consultancy Services has doubled the normal salary for freshers who have new-age digital skills.The Indian MNC is now offering up to Rs 6.5 lakh per annum compared to the Rs 3.5 lakh per annum it was offering until now.However, this is only for engineering freshers with new-age digital skills on which they will be tested before they are offered the job. They will have to sit for the National Qualifier’s Test where they would take the digital skills-based examination, according to TOI.”The NQT was open to graduates and postgraduates of the 2019 batch, across engineering colleges in India. This re-imagination of the campus hiring process, using sophisticated technology platforms, has transformed traditional recruitment models and reinforces TCS’ philosophy of being an equal opportunity employer,” TCS said according to a PTI report.TCS has had a 175 percent increase in test applications than before after the NQT was announced.”People who have done well in the NQT will get a chance to write another test for the digital talent pool, and if they clear and go through the interview, then they will get into the digital pool and their compensation will be differentiated,” Ajoy Mukherjee, executive VP and head of global human resources reports TOI.The test by TCS is longer and more difficult than the NQT and requires coding skills and a basic knowledge of artificial intelligence, machine learning and data intelligence. The exam will also test the candidates programming skills.

California Attorney General Kamala Harris (Twitter Photo)WASHINGTON – Kamala Harris, the California attorney general and the early odds-on favorite to become the state’s first Black U.S. senator, returned to her Howard University roots during homecoming week to raise money and reconnect with her sorority members, longtime friends and supporters.Harris, who political experts say is the frontrunner in the race to replace retiring Sen. Barbara Boxer, hosted a few private events and fundraisers last week to further solidify her network of supporters.“I came to reconnect with friends and supporters and hear their concerns,” she said.Howard, she said, has been a special place in her career and her life. “Howard is really a place that teaches us who we can be, and most importantly teaches us we can be anybody,” she said.The attorney general said it was important to meet with her fellow members of Alpha Kappa Alpha Sorority’s Alpha Chapter, which was founded in 1908 at Howard University.“My sorors support me spiritually and professionally,” Harris said. “That’s the great thing about a sisterhood.”Harris’ time at Howard was spent studying economics and political science, arguing on the debate team and working with Howard University Student Association (HUSA).It was at Howard where she won her first election, becoming the freshman class representative the College of Arts and Sciences. The experience molded her political career and sense of duty towards people who need their voices to be heard, she said.“I was working with HUSA in our tiny office creating priorities around folks that needed a voice,” she said.After graduating from Howard in 1986, Harris returned to her hometown in the San Francisco Bay area and earned a degree from University of California Hastings College of the Law. Harris was deputy district attorney of Alameda County and district attorney of San Francisco before receiving the Democratic nomination for California attorney general in 2010.One of Harris’ main priorities has been to reduce recidivism among California inmates. According to the California Department of Corrections and Rehabilitation 2013 Report, 61 percent of California inmates find themselves back in institutions within three years of release. Harris, California’s first Black woman attorney general, said as she talked with friends and others during homecoming week, they were focused on, “criminal justice reform, early education, minimum wage, the environment and immigration.”Harris said she hopes to influence young women to be persistent and determined in chasing their own success.“I always want to encourage young girls to never listen to or hear the word ‘no’,” Harris said, “I eat that word for breakfast. I hear ‘no’ maybe on the fifth time.”
Most of the web sites out there seem stumped as to how these guys pulled off this little trick. Fortunately, the researchers explain it in detail. And even more fortunately, it’s not that hard to understand.First a thin sapphire wafer is created. It is then coated with a very thin ceramic layer of yttrium barium copper oxide which becomes a superconductor (materials that conduct electricity with no loss of energy) at very cold temperatures. The result is a frozen disc. When it is placed over a magnet, the superconductor material and magnet repel one another due to the Meissner effect (the expulsion of the magnetic field from a material when it goes into a superconducting state). But, because the layer of superconducting material is so thin, some of the magnetic force is allowed through at certain particularly weak points. These paths through are called flux tubes, and they are the real secret to the whole trick. Because there are many of them they cause a three dimensional holding or locking effect, which is what viewers see when watching the video.Upon viewing the video, a lot of commentators refer to the scene in Back to the Future 2 when Mary McFly rides a hoverboard for a few minutes. Unfortunately, the science demonstrated in this latest video holds no hope for that; not unless someone figures out how to keep such boards frozen indefinitely (and embeds magnets everywhere) or better yet, figures out a way to make a superconductor that works at room temperature. This is nothing new of course, everyone’s seen it in science class. What is new is that when the demonstrator turns the disc, it stays hovered at that angle. This is in contrast to the wobbling we’re used to in such demonstrations. Next, the disc is set over a different surface where it is made to spin. But that’s only the beginning. The disc is then set on a track where it zips around in midair. And again, it can be made to do so at whatever angle is desired. Then, the track is turned upside down and the disc hovers below it, again zipping around. © 2011 PhysOrg.com Explore further Superconducting magnet generates world’s highest magnetic field at 24T (PhysOrg.com) — A video created by researchers at Tel Aviv University in Israel has the Internet buzzing. Though rather simple, it just looks really cool, hence all the attention. It’s a demonstration of quantum locking, though to non-science buffs, it looks more like science fiction come to life. In the video a disc, obviously frozen due to the vapor rising from its surface hovers over a surface.

Meteorite study suggests Mars’ ancient atmosphere may be locked in its rocky terrain Scientists believe that the Earth has experienced many episodes of global glaciation—where the entire planet is covered in ice, resulting in what is loosely termed, a “Snowball Earth.” To better understand climate change heading into the future, scientists look to the past. In this latest effort, the research team looked at an event known as the Sturtian glaciation—after a billion years with no ice on the planet at all, suddenly, the Earth was covered with the stuff for 55 million years. Until now, why this happened has been a mystery.To find out more, the team traveled to the Mackenzie Mountains—a part of the planet that has been found to be useful for plotting the past due to its glacial history. The researchers collected sedimentary rocks left by glacial movement along with rock samples found above and below them.The rock samples were all taken back to the lab where the researchers tested them for osmium and rhenium levels—the latter breaks down to the former over time, offering a way to determine the age of the rocks. Using this technique, the researchers were able to conclude that the Sturtian lasted for approximately 55 million years. The team also tested the rock samples for isotopes of the same two elements and that led to the discovery that carbon dioxide had been sequestered in them. This led to the development of a theory that suggests that volcanic activity prior to the Sturtian also led to the absorption of so much carbon dioxide (weathering opens up rock causing it to be more absorbent) from the atmosphere that the planet cooled until it eventually became a Snowball Earth.Moving forward, the question of whether the Sturtian was truly one long event, or if it was actually a time of many glacial increases and retreats will be further studied to better understand the mechanism behind such global extremes.

Although the initiation mechanism of these Neoproterozoic Snowball Earth events has remained a mystery, the broad synchronicity of rifting of the supercontinent Rodinia, the emplacement of large igneous provinces at low latitude, and the onset of the Sturtian glaciation has suggested a tectonic forcing. We present unique Re-Os geochronology and high-resolution Os and Sr isotope profiles bracketing Sturtian-age glacial deposits of the Rapitan Group in northwest Canada. Coupled with existing U-Pb dates, the postglacial Re-Os date of 662.4 ± 3.9 Mya represents direct geochronological constraints for both the onset and demise of a Cryogenian glaciation from the same continental margin and suggests a 55-My duration of the Sturtian glacial epoch. The Os and Sr isotope data allow us to assess the relative weathering input of old radiogenic crust and more juvenile, mantle-derived substrate. The preglacial isotopic signals are consistent with an enhanced contribution of juvenile material to the oceans and glacial initiation through enhanced global weatherability. In contrast, postglacial strata feature radiogenic Os and Sr isotope compositions indicative of extensive glacial scouring of the continents and intense silicate weathering in a post–Snowball Earth hothouse. (Phys.org) —A team of researchers conducting a field study in the Mackenzie Mountains in northwest Canada is suggesting rock weathering almost a billion years ago, may have led to the entire planet being encased in ice for 55 million years. In their paper published in Proceedings of the National Academy of Sciences, the multi-national team describes their field study and subsequent analysis of rock samples they retrieved and how doing so led to what they believe is an explanation of one of the most dramatic instances of climate change on record.
