SHERBROOKE, Que. – Surging water levels in a Quebec river have washed away part of a railway bridge east of Montreal.Genesee & Wyoming Canada Inc., which owns the St. Lawrence and Atlantic Railway, says the water levels in the St-François River rose overnight Friday night.No trains were involved and the damage affects only railway infrastructure.Genesee & Wyoming Canada says there were no injuries.A railway emergency and recovery team is on site in Sherbrooke to assess damage and prepare the ground for future work.Alternative routes will be established shortly to maintain customer service.
Workers at the General Motors plant in Oshawa have stopped working as they wait for details on the company’s plan to close the facility.A source familiar with the situation has told The Canadian Press that General Motors Canada will shutter the plant as part of a shift in global production that will also affect operations in other countries.Unifor, the union representing more than 2,500 workers at the plant, said it has been informed that there is no product allocated to the Oshawa plant past December 2019.On Monday morning, dozens of workers were seen walking out of the Oshawa Assembly Plant, with some saying they were very unhappy with news of the planned closure.One man said the union had told workers at the plant to go home and would be speaking with employees at an afternoon meeting.A spokeswoman for GM Canada said Sunday that the company had “no news or comment tonight” and would not be commenting on speculation.According to GM’s website, the Oshawa Assembly Plant employs 2,522 workers with Unifor Local 222. Production began on Nov. 7, 1953, and in the 1980s the plant employed roughly 23,000 people.
PITTSBURGH — Autonomous vehicles won’t be coming to your city anytime soon.Even the most optimistic of experts say it will be 10 years before the cars are everywhere, but others believe it will take decades.The biggest reasons are camera and laser sensors that can’t see through heavy snow or figure out where to go if lane lines are covered. Autonomous vehicles also have trouble with missing lane lines or poorly placed lines showing where to stop at intersections. They also are challenged by when to turn left in front of oncoming traffic.And a fatal crash last year involving an Uber autonomous test vehicle has rattled consumer confidence in the technology.Tom Krisher, The Associated Press
“He is also raising with the authorities the allegations regarding human rights violations, and meeting with a range of pro-Russian as well as pro-Ukrainian civil society representatives,” Ravina Shamdasani, a spokesperson for the Office of the UN High Commissioner for Human Rights (OHCHR), told reporters in Geneva.Mr. Šimonovic, the Assistant Secretary-General for Human Rights, is in Ukraine to stress the “paramount” importance of ensuring respect for international human rights laws and standards during these difficult times, Ms. Shamdasani stated.“He is assessing the human rights situation in the region, calling for respect for human rights and discussing options for the UN and international partners to assist in strengthening capacity on the ground where necessary.”Mr. Šimonovic, who is based in New York, was dispatched by Secretary-General Ban Ki-moon on a week-long mission to Ukraine to continue the UN’s high-level engagement with the country, to assess the human rights situation, and to develop recommendations for further action. Senior UN officials have appealed to all parties to de-escalate tensions and to engage in direct and constructive dialogue to forge a peaceful way forward in Ukraine, which has been witnessing unrest for several months. Tensions heightened last week as lawmakers in the autonomous Ukrainian region of Crimea, where additional Russian troops and armoured vehicles have recently been deployed, voted to join Russia and to hold a referendum on 16 March to validate the decision. Although Mr. Šimonovic had planned to travel to Crimea on Wednesday, it was announced today that he will not be able to do so due to logistical constraints, especially given the fact that the airport there is closed for flights coming from other regions of Ukraine. He will instead travel to Lviv. So far during his visit, he has met with the Acting Foreign Minister, the Ombudsperson, human rights defenders, the diplomatic community and the various UN agencies working in the capital, Kiev. He is due to hold further high-level meetings there on Friday.
The illicit substance in questionA passenger was on Tuesday afternoon nabbed by ranks with some 3283 grams of cannabis concealed in seven taped parcels on the Weldaad Public Road, West Coast Berbice (WCB).The suspect, a 28-year-old of Angoy’s Avenue, New Amsterdam, Berbice was intercepted at about 14:10h while enroute to Georgetown.This publication understands that acting on information, the ranks stopped the vehicle in which he was traversing in and searched him when the discovery was made.As such, he was taken into Police custody where he is presently being processed for Court.

Metals Economics Group (MEG) marks 2011 as a milestone-30 years as a leading provider of global mining industry information and analysis. It is celebrating the occasion with a new web presence, including an online store. Building on a (perhaps) “unmatched” level of historical data and essential current information, MEG continues to deliver increasingly powerful and comprehensive services that allow users to effectively address business-critical questions. Thirty years ago, the mining industry was much less information-oriented. Reporting of key competitive information, such as operating costs and exploration spending, was very spotty. Few companies had the research capacity to look at all the various print-based press releases and annual reports when they needed to compare projects, evaluate strategies, or look for opportunities.MEG started in 1981 with the objective of becoming the collector, analyser, and disseminator of the relevant worldwide information required to support planning and major strategic and tactical moves on the supply-side of the mining industry.But simply locating and reporting the raw data wasn’t sufficient.“We found that it was extremely important to not only be accurate about information but to pay very careful attention to context,” remarks MEG founder and CEO, Michael Chender. “It’s easy to throw around numbers and never realise you are comparing apples and oranges from one company or one project to the next. Carefully normalizing data such as that for reserves, costs, and spending is crucial for allowing efficient comparison of companies, projects, and activities.”MEG saw an opportunity with evolving personal computer capability and developed the MineSearch project database for use inside the company in late 1981. “When we started allowing client access to MineSearch in 1982, it was one of the first online databases in any industry. MineSearch sat on an IBM mainframe in Florida,” recalls Chender. “We had it on a time-sharing basis and would port information from our own smaller computers every month-information which our clients would then access through dial-up modems. When we showed a demonstration to a group of mining company librarians in Denver, nobody believed we were showing it to them live. They thought it was canned, simply because they had never seen an online database before.”With the advent of the World Wide Web, the whole landscape of information began to change. “Data and information became much more readily available and the noise-to-signal ratio rose quickly,” adds Chender. “Ensuring that client needs are met with information that is comparable and credible has remained as challenging as ever.”MEG migrated all its separate services to the Web a number of years ago and has been working for the past several years to migrate them all to a common interoperable platform, further leveraging the richness and depth of the data.Since its beginnings, MEG has used the information it collects to produce detailed analytical reports and studies. The Mine Development Monthly, later renamed the MEG Strategic Report, became MEG’s platform for providing insights into supply-side issues facing the global mining industry.As MEG’s industry knowledge expanded, consulting requests increased. Addressing specific requests helped MEG better understand how data was being used and what information was needed by the industry, and this resulted in the creation of numerous MEG products. Chender recalls how a few of those products came into being.“In 1989, we realised that companies were looking for information to benchmark their exploration activities. The key factor for companies was to understand what was going on in the field and what their peers were doing,” says Chender. “We began collecting information directly from the explorers, and the industry trusted us to be the brokers of this knowledge through MEG’s Corporate Exploration Strategies study.”Now in its 21st year, the Corporate Exploration Strategies study remains the industry’s only comprehensive source of detailed global exploration budgets and the acknowledged benchmark for exploration-related spending, strategies, and worldwide trends. MEG’s team collects and analyses exploration-related information from thousands of companies around the world, providing subscribers with both a global and a granular view of exploration strategies.Requests to evaluate acquisitions and exploration data resulted in MEG’s first study on comparing the costs of exploring vs acquiring-Reserves Replacement Strategies. The study provides a detailed examination of how, and at what cost, major companies are replacing their reserves of copper, gold, and nickel.“There are many assumptions around data-what a discovery is, when a discovery was made, what expenditures actually went into a discovery, whether the cost of acquisition includes future capital costs, etc.,” notes Chender. “We created a very sophisticated model so that our clients understand MEG’s definitions and reporting methodology. In addition to MEG’s analysis, the online tools that accompany our studies allow companies to apply their own assumptions to the data.”Continuous examination of client information needs led to the launch of the Industry Monitor in 2010. The bimonthly service assembles and collates exhaustive current data on exploration, development, financings, and acquisitions drawn from a number of MEG services.“The service reveals trends, provides an overview of where and how the whole supply pipeline is developing, and facilitates exploration of key strategic questions,” comments Chender. “Key indicators signal impending opportunities and industry shifts, allowing subscribers to makes forecasts and modify strategies.”MEG’s clients span the globe, including most major international mining companies, investment banks and fund managers, intermediate and junior mining companies focused on growth, service and equipment providers, governments, and consulting firms. The company has seen many changes and supported clients through many cycles.“Our success is measured by the thousands of users of our services who have gained competitive advantage and operational efficiencies, recognised windows of opportunities opening, and avoided threats sooner,” conveys Chender. “We work with our clients to understand their business objectives and to help them find the best solution for their specific needs.”MEG takes great pride in its experienced and knowledgeable team of analysts-combining a tremendous wealth of industry experience with fresh ideas from a new generation of geology-trained staff. MEG’s continuous development of its people, processes, and services are the foundation of the company’s success. Drawing on three decades of innovation and experience, MEG continues to deliver outstanding customer service and solutions in support of business goals, from exploration, development, and production to strategic planning and acquisitions.
Updated at 18.58RORY MCILROY JOINED the elite list of golfers to have won three of the four major titles at Hoylake on Sunday, but he had to battle all the way against Sergio Garcia and Rickie Fowler before bagging his first British Open title.At 25, McIlroy joined legends Tiger Woods and Jack Nicklaus as the only players to have achieved that feat by the time they were 25.The Co. Down man closed with a 71 for a 17-under par total of 271, two strokes clear of Garcia who closed with a 66 and Fowler with a 67.A further two strokes back came American Jim Furyk with a final round of 65. Australians Adam Scott (66) and Marc Leishman (65) were on 12 under.It was a magnificent wire-to-wire win from McIlroy, who is just the seventh player in Open history to to so, but the day was not without its share of drama.Starting with a whopping six-stroke lead, McIlroy confidently birdied the first, but back-to-back bogeys at five and six saw his lead halved as Garcia emerged from the chasing pack.But he birdied the 10th to keep his challengers at arm’s length and then stood firm down the back nine against Garcia and a late push by Fowler.His third major title follows eight stroke triumphs in the 2011 US Open and the 2012 US PGA Championship.DangerSuch was the majesty of McIlroy’s three first rounds of 66, 66 and 68 at Royal Liverpool that few believed he was in any danger of repeating his collapse at the 2011 Masters when he led by four strokes going into the final round only to shoot 80.And despite some early movement from such as Robert Karlsson, Marc Leishman and Victor Dubuisson, the rest of the field were too far behind to be able to apply any real pressure on the leader.But suddenly it changed after McIlroy’s back-to-back bogeys, followed shortly after by an eagle from Garcia at the 10th.The lead was back down to two and the Spaniard had a sniff of possibly finally winning a major title at the age of 34 after a long run of near misses.But he narrowly missed a birdie at the 11th and playing behind him, McIlroy grabbed another birdie at 10 to ease back to three ahead.Garcia saw his chances all but vanish when he took two shots to get out of a greenside pot bunker at the par-three 15th and a superb chip by McIlroy to set up par at the 17th sealed the deal.The man from Holywood had a three-stroke lead with a hole to play and he was able to enjoy a victory walk down the lastFor Garcia, it meant the Spaniard remains ranked second in most major starts without a victory with 62, trailing only Lee Westwood who has two more.Fowler, a 25-year-old American also seeking a first major title, never really got close enough to worry McIlroy apart from playing in the final pairing with him.Much prior to the day’s main action Tiger Woods struggled in with a 75 which left him 69th out of the 72 players who made the cut – his worst performance in the 18 Opens he has played in.Defending champion Phil Mickelson was never in the hunt as he closed with a 68 to get to five under and one of the biggest rounds of applause of the day went to 64-year-old five-time former Open winner Tom Watson who had a fine 68.But the day deservedly belonged to McIlroy and the focus will now inevitably switch to Augusta National next April when he will be in a position to become just the sixth player to win all four major titles during their career.Slow-mo replays, place-kicking and the World Cup; the week’s best sportswriting>Fancy watching the second oldest tennis tournament in the world in Dublin this week?>
DENVER — Three-fourths of Americans say it’s inevitable that marijuana will be legal for recreational use across the nation, whether they support such policies or not, according to a public opinion poll released Wednesday that highlights shifting in attitudes following an era of drug war and “tough on crime” legislation.The Pew Research Center survey also shows increased support for ending mandatory minimum prison sentences for non-violent drug offenders and doing away altogether with jail time for small amounts of marijuana. The opinions come as public debate on these topics has led lawmakers around the nation to consider policy changes. Since California became the first state to legalize medical marijuana in 1996, at least 19 others, and the District of Columbia, have followed suit, including two that have approved recreational use. More than a dozen state legislatures considered legalization measures this year. Meanwhile, critics and political leaders, both liberal and conservative, have clamored for an end to harsh drug sentences, saying mandatory minimums have contributed to prison overcrowding, civil rights violations and strained budgets. U.S. Attorney General Eric Holder has been pushing Congress to overhaul drug sentencing policies. The telephone survey found that 75 percent of respondents — including majorities of both supporters and opponents of legal marijuana– think that the sale and use of pot eventually will be legal nationwide.
A federal appeals court issued an opinion today saying the roadless rule should not apply to Alaska’s Tongass National Forest.Download AudioThe Tongass National Forest could resume allowing logging in roadless areas under a court ruling. But it won’t happen immediately — or at all. (U.S. Forest Service Image)The rule was enacted nationwide more than a decade ago. It prohibits logging and other industrial activity in national forest lands without roads.The Tongass forest, the nation’s largest, was later granted an exemption. That was struck down three years ago in U.S. District Court and the rule was re-imposed.The Forest Service did not appeal that decision, but the state of Alaska did. The 9th Circuit Court of Appeals granted its request. (Read the decision.)Tom Lenhart is the state attorney involved in the case.“Removal of the roadless rule won’t in and of itself increase timber harvests or mining or anything like that. But it will take down the barriers that are preventing some things from happening,” he says.The 9th Circuit Court’s decision does not immediately lift the rule. It sent the case back to the lower court to decide whether additional environmental review is needed.Buck Lindekugel is attorney for the Southeast Alaska Conservation Council. It’s one of a dozen groups that sued to bring back the roadless rule.“The reality is the decision does not immediately reinstate the Tongass exemption. And the Forest Service’s actions have shown it has no desire to go back to the damage, expense and controversy associated with roadless area logging on the Tongass,” he says.Forest Service officials referred calls about the ruling to the Department of Justice. The staffer handling the issue could not be reached for comment by this report’s deadline.Plaintiff’s attorney Tom Waldo of Earthjustice says the decision won’t change much. That’s because the Forest Service is already moving away from the type of timber sales the roadless exemption allows.“I think that’s where the future direction of the policy debate is going to lie, rather than trying to turn the clock back in time to fight the battle of the 1990s over whether we should be logging in roadless areas of old growth on the Tongass,” he says.The state has a different view.“We’re hoping the Forest Service will meet its obligations to seek to meet timber demand. And we feel that some sale from roadless areas is necessary to do that. I’m sure the state will continue to use every means available to encourage the Forest Service to take actions that will further a certain level of development,” says attorney Tom Lenhart.The state, the timber industry and other development groups have been pressuring the Forest Service to allow more logging.That includes a proposal for the federal government to turn over or sell some Tongass lands.

By ASHRAF KHALIL, Associated PressWASHINGTON (AP) — When Washington’s $500 million Museum of the Bible held its grand opening in November 2017, attended by Vice President Mike Pence, there were questions even then about the authenticity of its centerpiece collection of Dead Sea Scrolls.Now the museum has been forced to admit a painful truth: Technical analysis by a team of German scholars has revealed that at least five of the museum’s 16 scroll fragments are apparent forgeries.In this Oct. 30, 2017, file photo, security workers stand inside a large open stairwell area at the Museum of the Bible in Washington. Less than a year after it opened, Washington’s Museum of the Bible is admitting that at least part of its centerpiece collection of Dead Sea Scrolls are fakes. The embarrassing announcement on Oct. 22, 2018, is the culmination of a technical analysis by a team of German scholars. (AP Photo/Jacquelyn Martin, File)The announcement has serious implications not only for the Bible Museum but for other evangelical Christian individuals and institutions who paid top dollar for what now seems to be a massive case of archaeological fraud.Jeffrey Kloha, chief curator for the Museum of the Bible, said in a statement that the revelation is “an opportunity to educate the public on the importance of verifying the authenticity of rare biblical artifacts, the elaborate testing process undertaken and our commitment to transparency.”The scrolls are a collection of ancient Jewish religious texts first discovered in the mid-1940s in caves on the western shore of the Dead Sea in what is now Israel. The massive cache of Hebrew documents is believed to date back to the days of Jesus. With more than 9,000 documents and 50,000 fragments, the entire collection took decades to fully excavate.Most of the scrolls and fragments are tightly controlled by the Israeli Antiquities Authority. But around 2002, a wave of new fragments began mysteriously appearing on the market, despite skepticism from Biblical scholars.These fragments, they warned, were specifically designed to target American evangelical Christians, who prize the scrolls. That appears to be exactly what happened; a Baptist seminary in Texas and an evangelical college in California reportedly paid millions to purchase alleged pieces of the scrolls.Also eagerly buying up fragments was the Green family — evangelical Oklahoma billionaires who run the Hobby Lobby chain of craft stores and who famously sued the Obama administration on religious grounds, saying they didn’t want to pay to provide their employees access to the morning-after pill or intrauterine devices.The Greens are the primary backers of the Museum of the Bible and went on an archaeological acquisition spree in the years leading up to the museum’s opening. In addition to the alleged Dead Sea Scrolls fragments, the Greens ran afoul of the Justice Department, which said they had acquired thousands of smuggled artifacts looted from Iraq and elsewhere. The family agreed last year to return those artifacts and pay a $3 million fine.
On November 12 Microsoft will officially launch the backwards compatibility feature of the Xbox One. With it, a growing list of Xbox 360 games will “just work” on the newer console despite having a completely different architecture.The feature will launch with 104 supported games, the full list of which you can find at the end of this post. As well as being playable, Microsoft is supporting online play for the games that include it and with friends who still play on their Xbox 360. Microsoft explains how in the video below:There’s a bunch of additional features available, including screen capture, video recording, Twitch broadcasting, and game streaming to a Windows 10 PC/laptop.

What is it that makes Grumpy Cat so grumpy? These days it’s because she has to go to court because some company misappropriated her image to sell coffee.Four years ago, the Grumpy Cat meme took the Internet by storm. We couldn’t get enough of Tardar Sauce and her signature frown, and marketing departments took notice. That kicked off the second wave of Grumpy Cat as officially-licensed merchandise flooded store shelves.One of those products was Grumpy Cat Grumppuccino, which was bottled and sold by Grenade Beverage. Well, technically it was sold by Grumpy Beverage, LLC — a corporation specifically set up to market a line of iced coffee drinks with the feline sourpuss on its packaging… because, let’s face it, people will buy anything, especially if there’s a picture of something they recognize on it.Grumpy Cat and coffee go together like… well, any random product and an equally random famous thing.The cat claws didn’t come out until bags of Grumpy Cat roasted coffee went on sale. Grumpy Cat’s owners cried foul (or “unauthorized use,” anyway) and slapped Grenade Beverage with a lawsuit. They want Grenade punished for overstepping their bounds to the tune of $600,000 — $150,000 each for four transgressions. That’s the maximum they can seek, because Grumpy Cat Limited doesn’t mess around. You can’t when your CEO has a perma-scowl, really.Grenade has fired back, claiming that they forked over an advance payment of $150,000 without ever receiving “any continuing support” from Grumpy Cat Limited. They’ll be heading back to court next month to straighten things out, and only one thing is certain: Grumpy Cat won’t be pleased with the outcome no matter which side wins.
“Our experiment is based on the wave–particle duality, which is a basic concept in quantum mechanics,” Wieland Schöllkopf, one of the researchers who carried out the study, told Phys.org. “The idea that microscopic particles such as electrons, neutrons, atoms or even molecules exhibit wave-like behavior dates back to the 1920s, when Louis de Broglie introduced the particle wavelength, which today is referred to as the ‘de Broglie wavelength.'” Since de Broglie first developed his theory, researchers have carried out numerous experiments observing diffraction and interference, two wave phenomena that cannot be explained in a particle picture. The main aim of the study carried out by Schöllkopf and his colleagues was to investigate novel matter-wave diffraction methods that allow for coherent manipulation of atomic and molecular beams. “We observed diffraction of He atoms and D2 molecules scattering off from a grating structure,” Schöllkopf explained. “The latter is formed by a periodic array of polymer film structured on a gold-coated glass substrate. A variety of grating structures, all with identical period, but differing in the width of the polymer stripes, were made at UNIST in Ulsan, Korea. These gratings were used in the diffraction apparatus at the Fritz-Haber-Institut in Berlin, Germany.” The apparatus at the Fritz-Haber-Institut allowed the researchers to generate an intense beam of He or D2 with extremely narrow angular divergence. The generated beam is incident to the grating under grazing conditions, hence, the particles’ velocity component perpendicular to the grating surface is very small. “In previous experiments carried out at our lab, we have observed coherent reflection and diffraction from a grating structure under grazing incidence conditions,” Schöllkopf said. “This was attributed to ‘quantum reflection,’ which is a reflection mechanism different from classical reflection.” In classical reflection, as atoms or molecules approach a surface, they are affected by the atom-surface van der Waals force. This force leads to an acceleration towards the surface, with the particle ultimately bouncing off from the surface. On the other hand, in quantum reflection, the atoms or molecules already bounce back from the region in space dominated by the van der Waals force. Researchers at Ulsan National Institute of Science and Technology (UNIST), in Korea, and Fritz-Haber-Institut der Max-Planck-Gesellschaft, in Germany, have recently conducted a study investigating matter-wave diffraction from a periodic array of half planes. Their paper, published on Physical Review Letters (PRL), reports on the reflection and diffraction of He and D2 beams from square-wave gratings of a 400−μm period and strip widths ranging from 10 to 200 μm at grazing-incidence conditions.

Matter-Wave Diffraction from a Periodic Array of Half Planes, Physical Review Letters (2019). DOI: 10.1103/PhysRevLett.122.040401Hilmar Oberst et al. Fresnel Diffraction Mirror for an Atomic Wave, Physical Review Letters (2005). DOI: 10.1103/PhysRevLett.94.013203 A third reflection mechanism, which differs from classical and quantum reflection, is based on the diffraction of the de Broglie waves of atoms or molecules from the edges of half planes, which are very narrow ridges on a surface. This mechanism, first observed in Japan by Prof. Shimizu and his colleagues, is now referred to as “Fresnel diffraction mirror” due to its analogy with the edge diffraction of light waves in optics. In their study, Schöllkopf and his colleagues observed fully resolved matter-wave diffraction patterns, including specular reflection and diffracted beams up to the second diffraction order. They also found that as strip width decreased, diffraction efficiencies transformed from the known regime of quantum reflection to the regime of edge diffraction. “In our experiment, we observed the transition from quantum reflection for relatively large widths of the grating stripes to the regime at small stripe widths where edge diffraction dominates,” Schöllkopf said. “Furthermore, in addition to the specular (mirror-like) reflection seen previously, we observed intense grating diffraction beams up to second order.”The experimental findings collected by the researchers confirm a previously developed single-parameter model, which is commonly used to describe a variety of phenomena, including quantum billiards, scattering of radio waves in urban areas and the reflection of matter waves from microstructures. Moreover, their observations suggest that neither classical nor quantum reflection mechanisms are essential for the reflective diffraction of matter waves from a structured solid, as this can result exclusively from half-plane edge diffraction. “Our observations allowed us to make a quantitative analysis of the reflection and diffraction efficiencies,” Bum Suk Zhao from UNIST, the principle investigator of the study, told Phys.org. “This, in turn, allowed for an experimental test of the Bogomolny-Schmit model of half-plane array diffraction. According to this model description the phenomenon is fully scalable with respect to the wavelength and the dimensions of the half-plane array. As a result, for a given incidence angle, the scattering of atomic matter waves of 1 nm de Broglie wavelength from a 4-μm-period array of parallel half planes shows identical diffraction effects as, e.g., the scattering of 1-cm-wavelength radio waves off buildings separated by 40 m.” The study conducted by Schöllkopf, Zhao and their colleagues provides a clear confirmation of the Bogomolny-Schmit model. In the future, their findings could also be used as a test bench for models of quantum reflection from microstructured surfaces that need to account for half-plane edge diffraction. In their next studies, the researchers plan to apply half-plane array diffraction to the investigation of weakly bound molecules, such as the He dimer and trimer.”Due to their extremely small binding energies, these di- and triatomic helium molecules are not amenable to many experimental tools,” Bum Suk Zhao explained. “For instance, classical scattering of He2 from a solid surface will inevitably lead to break-up. To overcome these limitations, more experimental techniques allowing for non-destructive manipulation of these species are needed. Half-plane array diffraction is a well suited method for this purpose.” ‘Meta-mirror’ reflects sound waves in any direction Journal information: Physical Review Letters “This counter-intuitive quantum effect of attractive forces, effectively resulting in recoil of the particle, can only be observed if the incident velocity in the direction perpendicular to the surface is very small,” Schöllkopf explained. “This is why, in our experiment, we can only observe quantum reflection at near grazing incidence conditions.” © 2019 Science X Network Citation: Observing matter-wave diffraction from a periodic array of half planes (2019, February 20) retrieved 18 August 2019 from https://phys.org/news/2019-02-matter-wave-diffraction-periodic-array-planes.html A photograph of the research team taken inside a lab at Fritz-Haber-Institute, in Berlin.

Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 2 min read September 24, 2014 Last week, Sony released a software development kit for its smartglass – called SmartEyeGlass – and announced that a developer’s version of the wearable will be available in March 2015.In a blog post, Sony hinted at ways its smartglasses could be used, including a cooking app that displays recipe directions directly on the lenses, a pedestrian navigation app that directs users to nearby locations and a facial recognition app.While Sony claims its smartglass features a “slim light wear design,” the prototype — which includes a CMOS image sensor, accelerometer, Gyroscope, electronic compass, brightness sensor, and microphone — is bulky. So bulky, in fact, that it makes the awkward-looking Google Glass appear sleek in comparison. As Michael Andronico wrote for Tom’s Guide, after trying on the device, “it seems a few iterations away from something you’d want to wear on the street.”Related: Will Sony Get Its Groove Back?As Sony’s smartphone business continues to falter – last week the Japanese electronics giant announced it is expecting an annual net loss of 230 billion yen ($2.15 billion), nearly five times its forecast in July of 50 billion yen, due to losses from its embattled smartphone division – the company has invested in wearables, including a smartwatch and an activity wristband.”Sometime there will be a post-smartphone business, a new area of mobile communication business, and if that day comes we have to utilize our assets…we have to create the foundations of the smart business and evolution of that going forward,” Sony CEO Kazuo Hirai said.The slated launch for a Sony smartglass appears to be part of this strategy. No word on pricing yet. Currently, Google Glass retails for $1,500.Related: Would You Spend $1,500 on Google Glass? Opinions expressed by Entrepreneur contributors are their own.

When we think of energy, it tends to be in very broad-based terms: electric companies, oil refineries and green energy solutions. Technology companies, however, are playing a growing role in the energy sector.Opportunity awaits.It seems as though we’ve recently hit a wall in finding solutions for a greener world. We’ve harnessed wind power, converted solar rays and mass-produced electric cars. In the past few years, organizations have sprung up to help advance the greening efforts. But with fierce competition for capital, the kind of green that spends often is in short supply for sustainable causes. In contrast, the tech space is constantly innovating and appears to have no shortage of funders on the horizon.Related: 5 Exploding Niches Within TechAs companies realize the vast energy needed to operate cloud-based platforms and other emerging technologies, they understand they must do more than switch to smart bulbs and mobile-controlled thermostats. At the same time, energy companies are starting to see the need for updated technology. During the past three years, technology has skyrocketed in the energy sector. That’s particularly true for data collection services such as locating and extracting real-time information.New technologies allow oil and gas companies to monitor their equipment from start to finish. This gives them opportunity to streamline the refining process and produce more at a lower cost. The problem lies in maintaining profit upstream while lowering prices for consumers downstream. The tech industry isn’t quite ready to provide these solutions. Budgets of more than $20 million upward are projected to fund analytical programming capable of tracking all this streamlined data. In other words, huge business opportunities exist for tech companies who can take advantage of the increasing cloud-based need to run the energy sector more efficiently.Skepticism still exists.It remains to be seen whether the tech industry can build solutions that are appealing enough to be acceptable for major players in the energy industry. There’s plenty of skepticism about allowing technology to do the job of consulting. And there’s at least one self-fulfilling reason why: Data drawn from technology is consistently more simplified than data gathered by consultants. Related: How Analytics and Data Can Undermine LeadersMany energy companies make the issue even more convoluted. Leaders as Opportune LLP confirm that “energy firms have been widely reported as delaying or cancelling many billions of dollars in capital project additions. Technology consulting firms are vital to improving the capabilities of current working assets to optimize output until additional units can be put in service.” No one wants to reinvent the wheel — or the microprocessor chip. But it wouldn’t hurt to make the ride a little smoother. In the very near future, companies will need to adapt if they wish to reduce production costs and achieve greater efficiencies.Technology is just part of the solution.While data processing will continue to become more tech-savvy, we’ll still need analysts to sort through the data and provide context. Technology merely makes it easier for those analysts and consultants to find solutions that don’t require customers to pay higher prices. Energy leaders who loosen the reigns a bit will discover real excitement. After all, these very changes will allow their companies to perform at extremely high levels while enjoying lower costs.Visionaries who helm the largest energy companies stand to face the most resistance to new business models. The conventional wisdom has been to supplement upstream costs with downstream cash from end-users. But as oil prices drop for consumers, energy companies haven’t done much to change how they acquire it, or the expenses they incur. Energy companies already use technology to find stable wells below the surface. But they’re only starting to apply technology’s power to the analytical process and inform their consulting efforts. But there’s no denying technology is poised to become a huge player in the energy marketplace. And once analytical tech is implemented, energy companies will really start to fire on all cylinders.

Ex-FBI agent details raid on Phoenix body donation facility MINSK, Belarus (AP) – Authorities in Belarus issued an arrest warrant Monday for a Russian billionaire who co-owns the Moscow-based potash company Uralkali as a power struggle escalated over exports of the fertilizer.Belarus’ Investigative Committee said it had charged Suleyman Kerimov in absentia with “organizing the abuse of power” and issued an arrest warrant for him. The statement came a week after Uralkali’s CEO, Vladislav Baumgertner, was arrested in Belarus on suspicion of “abusing his powers.” Sponsored Stories The vital role family plays in society Forbes magazine has estimated that Kerimov, who owns 22 percent of the company, is worth $7.1 billion. If found guilty, the 47-year-old billionaire could face ten years in prison.In July, Uralkali, Russia’s largest producer of this key ingredient in fertilizer, pulled out of a trading venture with its partner in Belarus, raising fears in the former Soviet state of a pricing war with Russia. Analysts have described the arrests and allegations by Belarus as an act of retaliation against Moscow.The venture, which has been accused of fixing the price of potash, suddenly broke up in July when Uralkali accused Belarusian President Alexander Lukashenko of allowing state-owned Belaruskali to export potash independently. Baumgertner sat on the advisory board of the joint trading company, which controlled up to 40 percent of the global potash exports.Uralkali’s shares have lost 20 percent since it decided to quit the cartel and the price of potash has fallen by 5 percent to $390 a ton. Uralkali executives have said they expect the price to drop to $300 by the end of the year.Belarusian authorities said they suspect Uralkali officials of planning to cause a drop in the potash market by quitting the joint venture. Investigators in Belarus claim that Uralkali deliberately caused a market crash in order “to launch a strike on Belarusian producers, who were already regarded as competitors.” 5 things to look for when selecting an ophthalmologist Comments Share Milstead says best way to stop wrong-way incidents is driving sober New Valley school lets students pick career-path academies Former Arizona Rep.

Moscow last week threatened to ban Belarusian dairy imports and said it would cut oil exports to its neighbor, although it denied that these steps were motivated by the attack on Uralkali.Uralkali’s shares were down 0.9 percent Monday afternoon Moscow time.(Copyright 2013 The Associated Press.
