0Shares0000Jump for joy: Barcelona striker Luis Suarez celebrates his goal © AFP / Josep LAGOBARCELONA, Spain, Apr 5 – Barcelona coach Ernesto Valverde admitted his side were well below their best despite beating Roma 4-1 in the Champions League quarter-final first leg on Wednesday.Two own-goals, from Daniele De Rossi and Kostas Manolas, and a close-range finish from Gerard Pique, presented the Catalans with a flattering 3-0 advantage at the Camp Nou before Edin Dzeko snatched Roma a late away goal. But, just as the Italians looked to have grabbed a lifeline, Luis Suarez restored the three-goal cushion, by scoring a fourth in the 87th minute.It means Barca will head to Italy next week with a place in the last four firmly in their grasp but this was not a virtuoso attacking display.Instead, they benefited from two fortuitous own goals and some careless Roma finishing. They are unlikely to meet as generous an opponent in the semis.“We did not that have continuity in the game,” Valverde said. “We had some errors and there were times that we rushed into the attack, instead of having some control.”Barca also had referee Danny Makkelie to thank for not awarding Roma an early penalty, after Nelson Semedo pushed Dzeko in the back.Poster boy: Lionel Messi holds a framed poster celebrating his 100th Champions League goal ahead of Wednesday’s game © AFP / Filippo MONTEFORTE“They are already good on their own, they don’t need help,” Roma coach Eusebio Di Francesco said.“Tonight they had help both from the referee and from us.”After Cristiano Ronaldo’s spectacular bicycle kick for Real Madrid on Tuesday, even Lionel Messi, back from injury, endured a slightly frustrating night, his shots and dribbles for once meeting opponents rather than the net.Messi returned to the starting line-up after recovering from his hamstring complaint, as did Sergio Busquets, back after breaking his toe against Chelsea three weeks ago.But while Messi completed the 90 minutes seemingly unscathed, Busquets had to be replaced by Paulinho midway through the second half.“Busquets has played with some small discomfort for the injury he has,” Valverde said. “In the end he was suffering a lot and we have changed it, but that’s fine.”Barca led at half-time after De Rossi slid to prevent Andres Iniesta’s pass reaching Messi and inadvertently stabbed into his own net.Two goals in four second-half minutes then took the tie away from the visitors as Samuel Umtiti’s finish cannoned off both the post and then Manolas, before Pique sidefooted home from close range.Dzeko’s finish might have given Roma hope had it not been cancelled out by Suarez scoring a fourth, as Barca wrapped up a win that did not wholly reflect a scrappy performance.“The truth is we know that in the game we can and we must improve in several points,” Barca’s Ivan Rakitic said.“But we’re very happy for the work. When maybe you’re not playing at 100 per cent, you have to stay together, to be strong. 5-1 would be better than 4-1, to be more calm, and we know Roma will try to turn it around.”0Shares0000(Visited 1 times, 1 visits today)
Danny Welbeck’s double guided a heavily rotated Arsenal to a hard-earned 3-1 win over Brentford and into the fourth round of the EFL Cup.One of nine changes from the weekend win over Everton, Welbeck was on target twice before a splendid Alan Judge free-kick set up a tense final half hour at Emirates Stadium.The Championship side were emboldened and, for a period, pressed hard in search of an equaliser that ultimately never came, Arsenal stabilising adequately and eventually sealing Unai Emery’s sixth straight victory through substitute Alexandre Lacazette in stoppage time.

What it means: Gunners in syncThis kind of banana skin fixture could well have eroded some of Arsenal’s momentum, but Emery’s second string handled the occasion professionally when required and, at times, with real style.Emery’s decision to retain only Monreal and Mustafi on his starting XI was justified as the fluidity of the second goal demonstrated an entire squad operating on the same wavelength.Leno looks the partThough beaten by Judge’s free-kick – for which he could do very little – two moments in the first half served to illustrate how comfortably Leno can slot in should Petr Cech’s form tail off.The German recovered from a nervy early moment to instigate Welbeck’s second with a brave pass from the back, having not long earlier raced off his line to snuff out a counter-attack in true sweeper-keeper fashion.Guendouzi lapse punishedSupplier of the opening goal, Guendouzi undid that good work by offering Brentford a way back into the match after half-time. It was the teenager’s unnecessary foul on the edge of the area which Judge emphatically converted.3 – Danny Welbeck is the first @premierleague player to score in three different club competitions this season (League, Europa League and #CarabaoCup).

Los Angeles, Sep 16 (AFP) Male tennis players are almost three times more likely to be fined for losing their temper and smashing racquets than their female counterparts, The New York Times reported. Male players were slapped with 1,517 fines compared to 535 fines for females according to data compiled by officials at Grand Slam tournaments for the period covering 1998 to 2018. The figures obtained by the Times show that men received 649 fines for breaking racquets to 99 for women in tens of thousands of matches in the four Grand Slams over the last two decades. Men were fined 344 times compared to 140 for “audible obscenity” and 287 to 67 for unsportsmanlike conduct. Last week, Serena Williams accused the chair umpire Carlos Ramos of being a “liar” and a “thief” after she was cited for verbal abuse during the US Open women’s final against Japan’s Naomi Osaka. “Because I’m a woman you are going to take this away from me?” she said to the tournament referee Brian Earley. “That is not right.” In the post-match news conference, Williams doubled down on her claim there is a double standard when it comes to punishment. “I have seen other men call other umpires several things. I am here fighting for women’s right and women’s equality …. and for me to say ‘thief’ and for him to take a game it made me feel like it was sexist,” she said. “He’s never took a game from a man because they said thief. For me, it blows my mind.” She also smashed her racquet and threatened to make sure that the Portuguese umpire never worked another match of hers again in the second set of a 6-2, 6-4 loss to Osaka.advertisement “You will never, ever, ever be on another court of mine as long as you live,” she said during the on court outburst. “You are the liar. When are you going to give me my apology?” The incident led to scores of Williams’ supporters coming to her defence but also to widespread criticism, especially on social media, of the 23-time Grand Slam winner. Williams’ first code violation in the Osaka match was for coaching which women have received 152 fines compared to 87 for men during the 20 years.One factor in the disparity in the data is that men play best-of-five set matches in Grand Slam events while women play best-of-three. – 2009 meltdown – ================= This was not the first time Williams has had a meltdown at the US Open. In 2009, Williams refused to apologize after threatening to shove a ball down a lineswoman’s throat in an expletive-laden outburst. Earlier this year at the Indian Wells tournament, Williams berated a female reporter in the players’ lounge area for asking a question at a news conference about therapeutic use exemptions. One Australian commentator took issue with Williams’s claim she is fighting for women’s rights. “She is doing a terrible disservice to women’s rights, to the #metoo movement, to gender equality,” Caroline Wilson of the Australian Broadcasting Corp. said. “To say she’s fighting for women’s rights, when what she is, is a bad sport.” (AFP) AH

internet People have been experiencing slow internet since Monday morning as mobile phone operators have been asked to slow down internet speed in the morning for 150 minutes to check question paper leaks during the SSC examinations.The Bangladesh Telecommunication Regulatory Commission (BTRC) has instructed the operators to slow down internet speed from 8:00am to 10:30am from 12 to 24 February, says UNB.The instruction was given in a bid to prevent question paper leakage during the ongoing the Secondary School Certificate examinations, according to the BTRC.The internet was slowed down for 30 minutes from 10:00pm on Sunday as trial run following the directive of BTRC.Although the government took some measures to stop question paper leaks, the SSC question papers are being leaked out from the very first day of the examination.
Testing device for performance-enhancing drugs provides immediate results © 2018 Phys.org More information: Damith Perera et al. A platform for automated nanomole-scale reaction screening and micromole-scale synthesis in flow, Science (2018). DOI: 10.1126/science.aap9112AbstractThe scarcity of complex intermediates in pharmaceutical research motivates the pursuit of reaction optimization protocols on submilligram scales. We report here the development of an automated flow-based synthesis platform, designed from commercially available components, that integrates both rapid nanomole-scale reaction screening and micromole-scale synthesis into a single modular unit. This system was validated by exploring a diverse range of reaction variables in a Suzuki-Miyaura coupling on nanomole scale at elevated temperatures, generating liquid chromatography–mass spectrometry data points for 5760 reactions at a rate of >1500 reactions per 24 hours. Through multiple injections of the same segment, the system directly produced micromole quantities of desired material. The optimal conditions were also replicated in traditional flow and batch mode at 50- to 200-milligram scale to provide good to excellent yields. A team of researchers at Pfizer, the pharmaceutical giant, has developed an automated flow chemistry system that is capable of carrying out 1500 reactions over a 24-hour period. In their paper published in the journal Science, the group describes the system, how well it tested and its limitations.

Schematic depiction of the flow system. Credit: Science (2018). DOI: 10.1126/science.aap9112 Developing new drugs to treat human ailments is both expensive and profitable—researchers at pharmaceutical giants such as Pfizer are constantly looking for ways to develop new drugs that cost less which, in turn, will increase profits. In this new effort, the team at Pfizer built a machine that allows researchers to carry out and sample reactions every 45 seconds.At its most basic level, a lot of what pharmaceutical researchers do involves optimizing chemical reactions to discover which is best for scaling up for testing and producing commercial drugs—a process that is notoriously expensive because it is so time consuming. To speed things up, the researchers devised a platform that supports continuous flow of chemicals through a reactor coil for precise control of residence time, rate of flow, pressure and temperature. It also hosts two ultrahigh performance liquid chromatography devices, one for analyzing reagents, the other for analyzing the reagents as they emerge. The setup allows for pipetting reagents into solvent samples at nanoliter volumes prior to analysis with the chromatography devices.The researchers select a carrier solvent to flow through the device and then engage the sample device, which injects tiny amounts of reagents into similarly tiny samples of the solvent, and then test it to see what happens. They tested the system by carrying out 5,760 Suzuki-Miyaura coupling reactions with a host of reagents under varying conditions in just four days.The researchers note that while useful, the device is not suitable for use in commercial applications, in part because it cannot handle heterogeneous or biphasic mixes. They will continue to work with the device, hoping to expand its capabilities, and suggest other researchers might want to build similar systems for testing of their own ideas.

December 1, 2006 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Enroll Now for Free This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. 5 min read I don’t know about you, but I can’t wait for one of our nation’s last great monopolies to be subjected to free market competition. Internet protocol TV is what will finally give cable TV a real race for your money, and 2007 is the year it begins in earnest.I want my FiOS TV or DAVE.TV! I want multiple PCs connected to multiple TVs at Chez Hogan simultaneously playing news and different HBO content on my PCs, as well as PC videos, spread-sheets and e-mail on my TVs. I want to pause, play back or skip ahead in live TV programs. And before business trips, I want to use Google to fetch Gilligan’s Island episodes for my laptop.Unfortunately, this vision hasn’t come into sharp focus yet, and IPTV hasn’t reached my neighborhood. But triple-play IPTV bundles (broadband, voice and video) are available to millions of folks in communities large and small, from Boston to Pottawatomie, Oklahoma, to Beaumont, California. A potentially fruitful aspect of these deployments is a new connection between your PC network and entertainment constellation. For example, subscribe to Verizon’s FiOS triple play, and the tech installs a wireless router connected to a TV set-top box/digital video recorder that’s actually a 160GB server. It can save 120 hours of video and let you view different videos, live programming, or photos from a PC on three separate TVs.That’s just a first wobbly step toward converged PC/entertainment networks, which Parks Associates predicts will be found in 30 million American homes by 2010. Not all will include IPTV. There are thorny digital rights and regulatory issues to work out before IP becomes the lingua franca between PCs and TVs. But we’ve passed some important milestones, including super-fast internet access for a critical mass of consumers; PCs and handhelds with enough graphics and computing power to deliver quality video and audio; and big, high-resolution TV/PC flat panels available at commodity prices.More than 5 million people worldwide already subscribe to IPTV version 1.0, reports iSuppli. That number will triple in 2007. By 2010, there should be 63 million IPTV subscribers worldwide, says iSuppli vice president Mark Kirstein, about 13 million of them in the U.S.That’s not most of the viewing public by any means. But IPTV doesn’t have to supplant cable to dampen subscription rates and up the TV ante. It just has to be a viable alternative.Telecom Tuning InIronically, the main proponents of IPTV are the same telcos who’ve had their own monopolies undermined by cable competitors. AT&T and Verizon are committing billions to a last-mile fiber-optic build-out-in part to defend their best markets against cable phone offerings. But video is also the richest vein in the triple play and a brand-new way for even century-old ruraltelcos to serve less populated areas.”It’s amazing how quickly Verizon picked up 25 percent to 30 percent market share in some communities,” muses Kirstein, considering those customers were wrested from cable. Initially, IPTV providers will break in by highlighting multiscreen viewing, expanded DVR and more interactivity for prices comparable to cable. But eight separate studies have found double-digit cuts in cable rates when IPTV comes to town.The speed of deployment will depend on the outcome of a regulatory tug-o-war being fought in state houses and city councils nationwide. TV isn’t just any old free market where technology will win out. As many as 30,000 separate regulatory bodies have to give their blessing and receive their tribute.Besides expanded functionality, New TV ushers in expanded video on demand. Initially, it will be mostly the same content traditional cable pro-viders offer, says Kirstein. But cable is contractually bound to an Old TV establishment that’s conflicted about its digital rights and how many copies of what should be allowed on what platforms. The growth opportunity is not in the same mass-market content–it’s in channels narrowly focused on a particular sport, hobby, music genre or religion, says Kirstein, or foreign-language channels direct from overseas.The BBQ channel on DAVE.TV might not be your cup of sauce. But, as the MySpace/YouTube phenomenon demonstrates, there are millions of wannabe moviemakers out there. They’ll need hardware, software and services that iSuppli projects will constitute a $4.5 billion TV spinoff by 2010. And like blogs or podcasts, VOD offers a low-budget way for entrepreneurs to reach self-selecting, highly motivated customer sets.Imagine marketing to a very defined audience and supporting them with click-to-call URLs and how-to videos. The hallmarks of New TV will be more choice, more flexibility and much more interactivity between you and your customers.It won’t be your father’s TV.IPTV GuideA sampling of nationwide IPTV services:Akimbo: A $180 player and $10 a month bring an eclectic mix of 10,000 vids to your TV.AT&T U-verse: A wireless router hooked up to a set-top network lets three TVs display or record 80 hours of different traditional channels simultaneously.DAVE.TV: This content-sharing community proves anyone with a camera-phone can make movies.ITVN: A $100 player (free with a 12-month subscription at $10 per month) accesses a half-dozen reasonably priced channel packages.Verizon FiOS TV: Like AT&T U-verse, but you can record 120 hours of video and transfer PC pics and music to your TVs.Mike Hoganis Entrepreneur’s technology editor.

But this new-age way of viewing a television show didn’t help The Jetsons, as it only lasted 24 episodes before being cancelled thanks to poor ratings. The production company Hanna-Barbera (the minds behind The Flintstones and Scooby-Doo) gave it another shot and revived it in the ’80s with new episodes that ran in syndication from 1985 to 1987. The cartoon wasn’t around for all that long compared to some of its contemporaries, but its impact is an enduring one. True, there are some aspects of it that are a bit dated — you don’t see a lot of parents naming their sons Elroy nowadays — but it was remarkably prescient about where technology was headed.From interactive newspapers to video chatting, here are some of the inventions from The Jetsons that are a part of our world today.1.

Drivendata has come out with a new tool, named, Deon, which allows you to easily add an ethics checklist to your data science projects. Deon is aimed at pushing the conversation about ethics in data science, machine learning, and Artificial intelligence by providing actionable reminders to data scientists. According to the Deon team, “it’s not up to data scientists alone to decide what the ethical course of action is. This has always been a responsibility of organizations that are part of civil society. This checklist is designed to provoke conversations around issues where data scientists have particular responsibility and perspective”. Deon comes with a default checklist, but you can also develop your own custom checklists by removing items and sections, or marking items as N/A depending on the needs of the project. There are also real-world examples linked with each item in the default checklist. To be able to run Deon for your data science projects, you need to have Python 3 or greater. Let’s now discuss the two types of checklists, Default, and Custom, that comes with Deon. Default checklist The default checklist comprises of sections on Data Collection, Data Storage, Analysis, Modeling, and Deployment. Data Collection This checklist covers information on informed consent, Collection Bias, and Limit PII exposure. Informed consent includes a mechanism for gathering consent where users have clear understanding of what they are consenting to. Collection Bias checks on sources of bias introduced during data collection and survey design. Lastly, Limit PII exposure talks about ways that can help minimize the exposure of personally identifiable information (PII). Data Storage This checklist covers sections such as Data security, Right to be forgotten and Data retention plan. Data Security refers to a plan to protect and secure data. Right to be forgotten includes a mechanism by which an individual can have his/her personal information. Data Retention consists of a plan to delete the data if no longer needed. Analysis This section comprises information on Missing perspectives, Dataset bias, Honest representation, Privacy in analysis and Auditability. Missing perspectives address the blind spots in data analysis via engagement with relevant stakeholders. Dataset bias discusses examining the data for possible sources of bias and consists of steps to mitigate or address them. Honest representation checks if visualizations, summary statistics, and reports designed honestly represent the underlying data. Privacy in analysis ensures that the data with PII are not used or displayed unless necessary for the analysis. Auditability refers to the process of producing an analysis which is well documented and reproducible. Modeling This offers information on Proxy discrimination, Fairness across groups, Metric selection, Explainability, and Communicate bias. Proxy discrimination talks about ensuring that the model does not rely on variables or proxies that are discriminatory. Fairness across groups is a section that cross-checks whether the model results have been tested for fairness with respect to different affected groups. Metric selection considers the effects of optimizing for defined metrics and other additional metrics. Explainability talks about explaining the model’s decision in understandable terms. Communicate bias makes sure that the shortcomings, limitations, and biases of the model have been properly communicated to relevant stakeholders. Deployment This covers topics such as Redress, Roll back, Concept drift, and Unintended use. Redress discusses with an organization a plan for response in case users get harmed by the results. Roll back talks about a way to turn off or roll back the model in production when required. Concept drift refers to changing relationships between input and output data in a problem over time. This part in a checklist reminds the user to test and monitor the concept drift. This is to ensure that the model remains fair over time. Unintended use prompts the user about the steps to be taken for identifying and preventing uses and abuse of the model. Custom checklists For your projects with particular concerns, it is recommended to create your own checklist.yml file. Custom checklists are required to follow the same schema as checklist.yml. Custom Checklists need to have a top-level title which is a string, and sections which are a list. Each section in the list must have a title, a section_id, and then a list of lines. Each line must include a line_id, a line_summary, and a line string which is the content. When changing the default checklist, it is necessary to keep in mind that Deon’s goal is to have checklist items that are actionable. This is why users are advised to avoid suggesting items that are vague (e.g., “do no harm”) or extremely specific (e.g., “remove social security numbers from data”).
