“I’m not worried,” coach Diego Simeone said. “I’m calmer than ever because it’s a wake-up call, a call for more focus.”It also means five points stand between Atletico and Spain’s two grandees, who have swept up 13 of the last 14 league titles, with Simeone’s surprise triumph in 2014 the anomaly.That was Atleti’s first in 18 years and a surprise of such gigantic proportions, that even Barca’s fans applauded when it was signed off at the Camp Nou, in their own back yard.A repeat next May would be no less impressive but certainly more believable.In the four years since, Atletico have finished third, third, third and second, won the Europa League and gone to the final of the Champions League, only to lose to Real.But it was their business in the summer, or rather lack of it, that deepened the sense this could again be their year. Antoine Griezmann felt like a new signing after he snubbed Barcelona – and announced it in a documentary – while the arrivals of Thomas Lemar from Monaco and Rodri from Villarreal bolstered two areas of weakness.But defensive errors in the Super Cup win against Madrid have continued into the league, while Diego Costa, Griezmann and Lemar have yet to catch fire.“We have lacked a little bit of precision at the end of our plays and that’s why we didn’t score against Celta,” Simeone said.“But what is clear to me is that this start is the best thing that can happen to us.”Atleti will surely react and there was cause for optimism too over the international break, when their midfielder Saul Niguez proved himself the standout performer across two excellent Spain victories.But it means they can ill-afford another slip at home to Eibar on Saturday, particularly with the city derby at the Santiago Bernabeu fast approaching at the end of the month.– Courtois or Navas? –Their rivals could hardly have made a better opening under Julen Lopetegui, with a trip to come on Saturday to Athletic Bilbao, who will have not kicked a competitive ball in three weeks after their last match against Rayo Vallecano was postponed.Gareth Bale extended his sensational start to the season with a brilliant goal for Wales last week and Karim Benzema also appears a player transformed under his new coach, boasting four goals in three.The only doubt has been at the other end. If Thibaut Courtois retains his place in goal versus Bilbao, the temptation will be to conclude Lopetegui is plumping for the Belgian as his first-choice, ahead of UEFA’s recently named keeper of the year, Keylor Navas.“It’s clear that I have two excellent solutions,” Lopetegui told Cadena SER last week. “The decision we make, it’s not a problem. We have an idea in our heads that we will not make public and we will see where it takes us.”Luka Modric should make his second league start of the season, alongside the same clutch of Spaniards who helped inflict a 6-0 thrashing over his Croatia on Tuesday.Ivan Rakitic may be in for similar taunting as he returns to Barcelona, who face Real Sociedad on Saturday at Anoeta.With PSV Eindhoven to come at the Camp Nou three days later, Ernesto Valverde will have been relieved to see the likes of Lionel Messi, Gerard Pique and Jordi Alba resting up over the international period.FixturesFridayHuesca v Rayo Vallecano (10pm)SaturdayAtletico Madrid v Eibar (2pm), Real Sociedad v Barcelona (5:15pm), Valencia v Real Betis (7:30pm), Athletic Bilbao v Real Madrid (9:45pm)SundayLeganes v Villarreal (1pm), Espanyol v Levante (5:15pm), Real Valladolid v Alaves (7:30pm), Sevilla v Getafe (9:45pm)MondayGirona v Celta Vigo (10pm)0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Diego Simeone’s Atletico Madrid are five points behind Barcelona and Real Madrid just three games into the season © AFP/File / MIGUEL RIOPAMADRID, Spain, Sep 14 – Atletico Madrid were billed as serious contenders to win La Liga this season but three games in and they are already playing catch-up.A creditable draw away to Valencia was followed by a stodgy one-goal win at home to Rayo Vallecano.

Since Sarbanes-Oxley (SOX) regulations were passed after the Enron scandal, businesses, particularly those small and medium sized, have complained about Section 404 which they have viewed as being onerous to comply with. The problem has been with the language of the ruling. The vagueness of the SOX language has made many accountants and auditors interpret the law very conservatively. Accountants and auditors are often worried that they could be sued by the SEC or investors if fraud is discovered at a later date.The result has been that companies fees for auditing and accounting have soared. An AMR report shows that costs related to SOX have increased from $2.5 billion in 2002 to $6.1 billion in 2005.For companies targeting SOX with products, services and consulting, this has been good news. Many software vendors have targeted the problem with specialized software. Companies addressing the problem include IBM, Oracle, SAP AG and Microsoft. The Big Four accounting firms have also benefited.Proposed guidance for SOX compliance from the SEC is expected in December. The Wall Street Journal this weekend reported that the new language will relax requirements of Section 404 compliance. In the long-term that is likely to save companies money and provide them with confidence that their procedures are compliant. But in the short-term it may mean that recently implemented processes for achieving compliance will again need to be reviewed, changed and updated.
Slamming the Centre over alleged lack of transparency in the ongoing Naga peace talks, former Union Minister Jairam Ramesh has said that the Congress will oppose any agreement, if it changes the geography of Manipur and any other northeastern State. A six-member Congress delegation arrived here on Sunday to take stock of the situation in Manipur arising out of the Naga peace talks and gather the opinions of people and party leaders on the National Register of Citizens (NRC).“There is no transparency regarding Naga peace talks on the part of the central government. The progress in the ongoing Naga peace talks has not been disclosed,” Mr. Ramesh told reporters at the Congress Bhawan here. Any accord which would change the geography of any State of the northeast region, including Manipur, will be opposed by the Congress, he said.“During the tenure of former prime minister Rajiv Gandhi, the Centre had signed Assam, Mizoram and Tripura accords “without changing the geography of any state”, the senior Congress leader said. The former Union Minister was accompanied by AICC general secretary Mukul Wasnik, former union minister of state Jitendra Singh, MP Manickam Tagore, AICC secretary Ranjit Mukherjee and Mohammed Ali Khan. Last week, the Union Home Ministry had said that lot of rumours and misinformation was being spread that the final Naga settlement had been arrived at and would be announced soon.“This is creating anxiety and concern in some parts of the country. It is clarified that before any settlement is arrived at with Naga groups, all stakeholders including states of Assam, Manipur and Arunachal Pradesh will be duly consulted and their concerns will be taken into consideration. No credence needs to be given to such rumours and incorrect information,” the MHA statement had said. Former Manipur Chief Minister O. Ibobi Singh said that the Centre, according to media reports, has rejected the NSCN-IM demand for separate flag and Constitution during the Naga peace talks.“People in Manipur are confused whether the demand for greater Nagaland has been accepted or not. If it is accepted by the present government, the party will oppose it tooth and nail,” the Congress Legislature Party leader in Manipur said.
REDWOOD CITY, Calif. — Leaders of the U.S. Olympic Committee are sticking with Boston as a candidate for the 2024 Olympics, knowing full well that getting the city to the starting line in this contest could be as tough as actually landing the games.The USOC board met June 30 to discuss the Boston bid, which has been troubled by tepid polling data and opponents who, among other things, don’t want taxpayers footing the bill for a huge international event.Thoughts that the board might turn elsewhere or pull the plug altogether were put on hold. They were replaced by a show of support for the Boston 2024 team, now under new management, along with a not-so-subtle nod to the reality that the city needs to find a support level among its residents well above the current low to mid-40 percent range.“We want to see a positive trend, and the sooner the better,” said USOC Chairman Larry Probst, who was joined by CEO Scott Blackmun and the leaders of the Boston bid at a news conference.“We want to see it get to 50 percent relatively soon, and ultimately get to the mid-60s range, certainly before the vote of the IOC.”That vote comes in 2017, but the key date is Sept. 15, 2015, which is when all cities must declare themselves candidates. Probst made reference to “circling back” with the Boston leadership in the next few weeks, and both Probst and Blackmun said they’d be monitoring the polling numbers carefully.Boston joins Paris, Rome and Hamburg, Germany as the officially declared candidates.Had the board wanted more certainty, it could have ditched Boston and looked to Los Angeles — an awkward and difficult choice that may have netted a better final result because Los Angeles has hosted the Olympics twice and there has been talk that some IOC members would like a “safer” American choice.Instead, the USOC said it was all-in with Boston, which unveiled its new “Bid 2.0” to the public on June 29.“I’ve seen their presentation five times in the last six days, and each time, it keeps getting better,” Probst said.So, the board decided the right thing to do was to see how that plan plays out before simply walking away.The $4.6 billion blueprint was filled with before-missing specifics about venues and cost. Probst and Blackmun said they were impressed with the man who will oversee it: Celtics co-owner Steve Pagliuca, who replaced John Fish as chairman nearly six weeks ago.“We’ve had so many conversations with Scott that he hasn’t had time to talk to anyone else,” Pagliuca deadpanned, after Blackmun was asked if anyone at the USOC had, in fact, had conversations with Los Angeles.The answer: An emphatic “No.”“We’re focused exclusively with Boston,” Blackmun said. For now, at least.A referendum on the Olympics is set for next year in Massachusetts and Boston 2024 leaders have vowed to pull out of the race if it doesn’t win.That’s why the polling trends are so crucial, and that’s why the “announcement” certainly doesn’t end this debate, but rather, kicks it down the road.Much of the handwringing in Boston has been about public funding. Pagliuca described an intricate, $128 million insurance plan that gave Boston “five levels of protection” against cost overruns, contractor bailouts and the sort of things the IOC wants guarantees for before awarding its premier event to any city.“Nothing in life is risk-free,” Pagliuca said. “I could walk off the podium and trip on the carpet. But this is five layers of protection. People will look at it and say the risk is limited and small, but the reward is great.”His task is to get the word out about the 4,100 construction jobs, 7,000 new apartment units and $362 million in tax revenue that a Boston Olympics could generate.He has a big sales job ahead. Shortly after the news conference, the opposition group “No Boston Olympics” tweeted pictures of residents at a rally. Many held up signs saying schools and infrastructure were higher priorities than hosting the games.“Citizens want better schools, better transit, not a 3wk, taxpayer-backed event in 2024,” the tweet said.All this is set against a backdrop that indicates now should be a great time for the United States to be bidding.The U.S. hasn’t hosted a Summer Games since 1996. An Associated Press-GfK poll from last week found 89 percent of Americans would like to see the an Olympics on home turf, though the support dwindled to 61 percent when respondents were asked if they would want the games in their local area.“I love seeing those polling numbers,” Blackmun said. “They speak to the fact that, as a nation, we want to see the Olympic Games in the United States. … The games always create questions in the city where they’ve been chosen to be held.”(EDDIE PELLS, AP National Writer)TweetPinShare0 Shares
In terms of dovetailing HTML5 development with standard app product development, Weinberg says the two are separate, but related, operations. “The apps are done in a separate group, but they’re aware of what we’re doing and we’re aware of what they’re doing. We all have shared but slightly different missions in this. For instance, an app in the future can be designed to link to the Web site for certain information or slideshows or content that the user wouldn’t have wanted to download as part of the native app. What’s really cool about that is it gives us a seamless consumer flow opportunity for delivering whatever content wherever they are whenever they need it through whatever device they have. My only issue right now is if we can go faster to implement more of the HTML5 products more comprehensively across all of the brands my life would be much better.”Next StepsGoing forward, Christie says HTML5 Web apps will be built on a case by case basis. The trigger will depend on the brand’s business model. “We are looking at HTML5 for some of the other FT Group titles. They’re more pure b-to-b titles. For some of them we are probably going to come out with more native apps. Some we might do Web apps. We’re looking at the business model for each of those and being quite pragmatic about it because for titles that have no registration, no subscription and are completely ad-based, you don’t have to do a Web app, you can do a native app. It just depends on where you see the future of each of the titles.”As an example, Christie cites the release of FT’s native How to Spend It app, which is available in Apple’s App Store. “From a business model point of view we don’t require registration or subscription and it’s completely advertising-based. It wasn’t going to compromise our business model to launch it in iTunes because we didn’t have an issue with the subscription process.”As for Weinberg, he sees HTML5 as a way to position the brands for whatever new features become available in the near future. “I’m looking down the road and saying this is going to create new creative capabilities that we haven’t had before and to the extent that it’s possible now, great. To the extent that it’s going to become possible later, all the better. But it does start to chart a new course for what the digital desktop is and how it works.” In the case of Hearst, the company is doing both. In September, the company announced that it was beginning the process of converting all of its magazine Web sites to HTML5. The plan was to build out specific components within the sites optimized with the new standard starting in the fourth quarter of this year and continue into 2012. The first to get the treatment was GoodHousekeeping.com, which went live in September and became compatible with the majority of mobile devices—meaning rich media elements were touch and swipe enabled, among other features.“This project forms the basis for the kind of site structure that we expect to roll out to the rest of the network over the next six to 18 months,” Mark Weinberg, vice president of programming and product strategy for Hearst Digital Media, said at the time. “We have a number of sites that we’re in the process of redesigning and relaunching now and they will be relaunched fundamentally on the same kind of code base of HTML5 and they will be designed to be multi-platform. The kind of innovations we’ve baked into the Good Housekeeping relaunch will drive where we go with the rest of the network sites.”Going All-inThe decision to go all-in with the entire stable of Web sites was largely influenced by the belief that mobile is going to be a huge influence on digital content access in the near term. “The major motivator for us was both the recognition that it would create a more future-oriented programming and content delivery approach, given that it is an evolutionary step for the Web as a whole, but also, very importantly, that it was an evolutionary step that would allows us to have a functional site on iOS devices,” says Weinberg. “That’s what really got us started down the road—looking at the iOS devices and the clarity that had about not adopting Flash. Continuing down the road using Flash was not a good idea. While we’re still using Flash in some places, it was very clear that we needed to be compatible.”As the strategy got underway, Weinberg realized that ditching Flash was not the only benefit. Consumers, as they use their devices more often, are expecting to have the same functionality wherever they go on the Web. “Once we got going it became clear that it would allow us to do a number of other things, not the least of which was to be functional on touch-screen devices. And that I think is one of the really future-oriented aspects of this—that people are beginning to expect that. So this really meets consumer expectations. It makes us flexible and functional on all devices and it gives us the functionality that you get with HTML5 that its predecessor didn’t have,” he says.That freedom from the confines of proprietary formats and the ability to give customers what they expect were similar motivators for the Financial Times when it developed its Web app and snubbed Apple’s App Store. But fundamentally, it’s about the explosion in mobile usage. “An obvious trend is device proliferation,” says MB Christie, online product manager for the Financial Times. “Users expect to get everything everywhere. Everything they have on the desktop they are absolutely expecting to get on the phone and on the tablet. They just expect it to be there and don’t think about the fact that there’s a different transition, a different screen size and there will be different interactions [with the content].”Yet with that proliferation of devices comes a proliferation of formats and operating systems, each having unique access requirements. “So as publishers we have to think about how to do this quickly and get on all of the devices without breaking the bank,” says Christie. “Because you’ve got to make sure you’re on all the different sized tablets, all the different sized small screens and still on the desktop—all with an optimal user experience. Otherwise, your users will think, ‘They have a really nice Web site, but I can’t use it when I’m on the go.’ And then they’ll stop using you altogether. It will hurt your brand.”Christie notes that in order to cover the bases in terms of device coverage, HTML5 was the clear path. “You have to think about how you can do it across the board, which is what prompted us to start looking at an HTML5 solution very early on.”Is It Ready Yet? For now, publishers are taking one of two paths. They’re either rebuilding their Web sites with the HTML5 standard that lets users view them from a mobile or desktop machine, or they’re building HTML5 sites designed specifically for mobile devices as a separate option from providing apps through the app store. Now that the early enthusiasm behind generating magazine apps for tablet and smart phone devices has settled into a more or less pragmatic approach for publishers, a nagging question is bubbling ever closer to the top of digital content development efforts for the mobile platform: HTML5 or native apps? A concern from the start for Weinberg and Christie was HTML5’s readiness. The standard was essentially still under development and certainly not as established as HTML4 and there wasn’t yet a large base of developers skilled in the standard. “It does take some skilled developers, but I think the speciality is improving. The more demand there is in the market the more people will pick up the skills needed to do this,” says Christie. And then around that time Apple and the FT bumped heads on App store subscription terms and customer data. “That’s when we decided to seriously focus attention on the Web app,” says Christie. “What was great was we could sell the idea because we already had it in front of us. We weren’t scared, it didn’t feel like such a big leap for us because we had a working prototype.”According to Christie, an early challenge was figuring out how to make offline caching a smoother experience. Mobile browsers limit file sizes for downloading and in order to read the Financial Times offline, users had to take the semi-technical and extra step of boosting the database size to 50 MB. “We had to come up with a way for us to allow people to store a fairly large amount of data. They had to go through an extra step of saving a larger database than the browser would normally allow them to. Making the message user-friendly and not scary was challenging.”The step allows the user to save the file to their homescreen, enabling them to open the FT and read it whenever they want to.That local caching on the device is a critical feature, and one that differentiates a Web app from standard mobile sites, such as FT’s m.ft.com. “The Web app has a lot more advantages. It allows for a lot more richness than the pure mobile site, m.ft.com. We can have videos, images and most importantly, you can read it offline. That is a huge advantage of an app over a straight old mobile site. It’s more like a newspaper. You can take it on the train and read it,” says Christie.Where a reader is directed to depends on the device they’re using. “We can look at your device and the we serve you the right site, whether it’s m.ft.com or the Web app. We look at how smart your phone is and then we serve you the right thing based on that,” adds Christie. At Hearst, the process of rebuilding the sites took a templated approach. Specific components were optimized for HTML5, such as promo players and other features, and then repeated throughout the rest of the sites. “We’re creating products, which are essentially features or functionality that can then be cascaded into all the sights in our network. It’s a build once, use many approach,” says Weinberg.For example, the promo player, which is basically a rotating slideshow that graphically features the top stories on the site, was one of the first to get the HTML5 treatment. “Historically, those were all Flash-based and after we developed the HTML5 promo player for Good Housekeeping, we cascaded that to all of our brands. Now, when you open any of the sites on an iPhone you will have a touch/swipe-enabled promo player that you can actually see. In the old version you couldn’t even see it because it was Flash. And it works on all phones, all devices,” says Weinberg.In all, Weinberg says the process of rolling out HTML5 is more of a design process than a technical one, and the templated approach as made it easier to apply the new features across the Hearst network of sites. “The team has made it very modular, so that the areas where we need to make these kinds of improvements in the near term we can make them in a more seamless way. The implementation of HTML5 is relatively easy. For example, we’re about to roll out our slideshow, or what we call a Flipbook, so there’s an HTML5 version of that that we’re cascading across the network. So by January almost all of the rest of our sites will have it. That’s how quickly it can cascade out. It’s much more of a design iteration than it is a technical challenge.”The FT began experimenting with an HTML5 Web app in the summer of 2010, says Christie. “We worked with one of our development partners and gave them time to play, really. It was just a few months after we’d launched the iPad app. We didn’t do anything really formal, and by January/February we had a pretty nice proof of concept going.” Browser compatibility had been one hurdle, but that has since been resolved says Weinberg. “So we weren’t really as worried at the time we were doing this work as those who came before us that people wouldn’t be able to see it or use it. In fact, we looked at it as the opposite, that this would increase the usability and increase the good functional behavior across more platforms and for more consumers in more circumstances. That actually proved out to be the bigger idea.”Another key motivator is the fragility of print revenues. As a stark reminder, consumer magazine ad pages fell 5.6 percent in the third quarter of this year, erasing the growth from the first six months of the year, per PIB numbers. Prior to the third quarter, consumer magazines enjoyed a run of growth for five consecutive quarters.“Print advertising money is no longer as easy to get as it used to be,” says Christie. “So that means that we all have to look for other solutions and digital is an obvious way. So we need to make sure that we are selling things on digital, whether it be ads, subscriptions or a combination. But in order to pay for the content, to pay our journalists, we absolutely need to make sure that we have a clear and strong digital strategy that will succeed and bring in the revenue needed to do so.”For the FT, the strategy is proving out, as is the theory that mobile is becoming a larger and larger component of media access. According to reports, the FT’s online operation now accounts for 30 percent of its revenues. Digital subscriptions were up 34 percent in the first half of 2011 and FT’s Web app reached the one millionth registrant milestone mid-November.Execution The latest Web standard has opened up new opportunities for building mobile-optimized content that, on the surface, frees it from the constraints of proprietary formats, such as Adobe’s Flash, and Apple’s onerous control of the app store retail environment and customer information. The Flash problem has largely been answered now that Adobe is no longer supporting it for mobile, but some publishers have been moving quickly to optimize both their sites in HTML5 and build products based on the standard to head off what they think is an inevitability: Mobile is going to be core to any content publisher’s product strategy going forward, and HTML5 is promising a seamless access standard that makes it easy for customers to view content on any mobile platform. “It did take a bit of a leap of faith,” adds Weinberg. “From what I understand there was a reluctance for people to move down this road for two pretty obvious reasons. One was it was not yet fully developed and so there were some concerns that people had about how the behaviors would work and what the issues might be; and there wasn’t as full of an understanding as there was with HTML4.”

More information: Evidence for a Dusty Dark Dwarf Galaxy in the Quadruple Lens MG0414+0534, arXiv:1701.05283 [astro-ph.GA] arxiv.org/abs/1701.05283AbstractWe report the 4σ detection of a faint object with a flux of ~ 0.3 mJy, in the vicinity of the quadruply lensed QSO MG0414+0534 using the Atacama Large Millimeter/submillimeter array (ALMA) Band 7. The object is most probably a dusty dark dwarf galaxy, which has not been detected in either the optical, near-infrared (NIR) or radio (cm) bands. An anomaly in the flux ratio of the lensed images observed in Band 7 and the mid-infrared (MIR) band and the reddening of the QSO light color can be simultaneously explained if we consider the object as a lensing substructure with an ellipticity ~ 0.7 at a redshift of 0.5≲z≲1. Using the best-fit lens models with three lenses, we find that the dark matter plus baryon mass associated with the object is ∼109M⊙, the dust mass is ∼107M⊙ and the linear size is ≳5kpc. Thus our findings suggest that the object is a dusty dark dwarf galaxy. A substantial portion of faint submillimeter galaxies (SMGs) in the universe may be attributed to such dark objects.

Dozens of new ultra-diffuse galaxies discovered in Abell 2744 MG 0414+0534 is a quadruply lensed, radio-loud quasar that showcases a strong sign of anomaly in the flux ratio and reddening in the optical and near-infrared band. This anomaly baffles scientists as its origin is not fully understood yet.In order to reveal more insights into this mysterious anomaly, a team of researchers led by Kaiki Taro Inoue of Kindai University in Japan conducted continuum observations of MG 0414+0534 with ALMA. The observational campaign, which was carried out in June and August 2015, resulted in the discovery of a faint object with a flux of about 0.3 mJy in the vicinity of the quasar. For the purpose of the research, this newly found object was designated “object Y.”According to the paper, “object Y” has an ellipticity of about 0.7 at a redshift between 0.5 and 1.0 and its linear size is at least 16,300 light years. The scientists estimate that the dark matter plus baryon mass associated with the object is about one billion solar masses, while its dust mass is approximately 10 million times greater than that of the sun.The images obtained by ALMA allowed the researchers to draw conclusions that the newly detected object is most likely a dusty dark dwarf galaxy, previously undetected in either optical, near-infrared or radio bands.”Our findings suggest that the object is a dusty dark dwarf galaxy,” the paper reads.However, the astronomers also explore the possibility that “object Y” could be an UDG. With stellar masses typical of dwarf galaxies, UDGs are extremely-low-density galaxies. The largest UDGs have sizes comparable to the Milky Way but contain only about one percent as many stars as our home galaxy. Notably, the phenomenon of UDGs still puzzles scientists as they try explain why these faint but large galaxies are not ripped apart by the tidal fields of their host clusters.The researchers explain that if “object Y” is a UDG, then its stellar components may have been expanded due to outflow caused by starburst or active galactic nucleus (AGN) activity. Therefore, the surface brightness in the optical and near-infrared band can be extremely small despite being gas-rich, which makes this object difficult to spot.The team concluded that more detailed analysis of the newly found object could provide important information about the origin of past starburst activity. They also noted that if “object Y” is residing in the intervening line of sight, many faint submillimeter galaxies may be classified in the future as gas-rich dusty dark dwarf galaxies.”A substantial portion of faint submillimeter galaxies (SMGs) in the universe may be attributed to such dark objects,” the researchers wrote in the paper.
