TORONTO – Prime Minister Justin Trudeau met with the founder of the Invictus Games hours before the competition for wounded veterans was set to get underway.Prince Harry and the Prime Minister exchanged laughs and pleasantries at a downtown Toronto hotel shortly before both were expected to attend the opening ceremony of the Games.Harry told Trudeau that the event had created “a real buzz around Toronto,” which will play host to the Games for the next week.Trudeau, in turn, thanked Harry for founding the Games and creating opportunities for veterans.Harry will meet with Gov. Gen. David Johnston before attending the star-studded opening ceremony at the Air Canada Centre, which will feature performers such as Sarah McLachlan and Alessia Cara.A few well-wishers gathered outside the room where Harry and Trudeau were meeting, though the crowd paled in comparison to the one assembled to greet the prince earlier in the day when he touredone of Canada’s premier mental health facilities.
COPENHAGEN – American rapper G-Eazy has cancelled a partnership with H&M after the Swedish clothing retailer was accused of racism over a promotional image of a black child dressed in a hoodie reading “coolest monkey in the jungle.”The rapper, whose real name is Gerald Earl Gillum, tweeted that he decided “our partnership needs to end” after seeing “the disturbing image,” joining singer The Weeknd, who has said he would end his ties with the company where he has a clothing line.H&M reiterated Wednesday its “humble apologies,” adding “we have got this wrong.”The retailer said in an email that “we completely understand and agree with the reactions by The Weeknd, G-Eazy and others.”NBA star LeBron James and rapper Diddy were among those who earlier had responded with outrage.
COPENHAGEN — In a symbolic first, electric cars outsold fossil fuel-powered ones in Norway last month.Christina Bu, the Norwegian Electric Vehicle Association’s general secretary, says sales figures show 58.4 per cent of new cars sold in the country in March were battery-powered, calling it “historically high.”Bu added Monday that electric cars’ share of the market in the first three months of 2019 was 48.4 per cent and is expected to hover around 50 per cent for the whole year.Norway has waived hefty vehicle import duties and registration and sales taxes for buyers of electric cars to boost sales. Owners don’t pay road tolls and use bus lanes in congested city centres. The aim to have all new cars in the Scandinavian country be electric by 2025.The Associated Press
Rabat – The International Mathematical Olympiad (IMO), held from Thursday, July 11 to Monday, July 22 at the University of Bath in the United Kingdom, saw a spectacular performance from the Moroccan team. The team took home a bronze medal as well as four honors, winning a total of 80 points.The competition saw Morocco’s best performance in 15 years, with the team placing 64th in the world ranking of 112 countries.

It has gradually expanded to over 100 countries from 5 continents.
15 September 2009Road traffic should get quieter in the near future, thanks to a new procedure for measuring noise in vehicles, according to the United Nations Economic Commission for Europe (UNECE). The new test, known as the Additional Sound Emissions Provisions (ASEP), is currently under development by the World Forum for Harmonization of Vehicle Regulations, which is managed by the UNECE. “ASEP is a completely new way of measuring noise levels and it will provide a more accurate measurement, because cars will be regulated in a broader engine speed range,” said Christian Theis of Germany’s Transport Ministry. “The ultimate goal of ASEP is to prevent tweaking of test results,” he added. Growing noise levels in urban areas have caused mounting concern recently as noise pollution can have serious adverse effects on human health and the environment. The World Forum limits sound from passenger cars at 74 decibels and has adopted a regulation on reducing the sound of tyres. Road surfaces can also play a role in reducing noise. In another development, UNECE announced that it would sign a Declaration for Road Safety during the EuroBasket 2009 tournament in Poland today, with the cooperation of the International Basketball Federation FIBA, the Polish Ministry of Infrastructure and the Polish Ministry of Sports and Tourism. The Commission said the new Declaration was aimed at offering a new perspective on traffic rules, emphasizing respect for fellow road users, rather than the “avoid getting caught” mentality.
Blackberry has signed a deal with Ford Motors to expand the use of the firm’s automotive and security software in Ford vehicles. A team of Blackberry employees will work directly with Ford to increase how its technology is used to create safe, connected vehicles. According to The Canadian Press, the head of Blackberry QNX, John Wall, said they hope to sign similar deals with other automakers in the future. Blackberry’s QNX software already powers Ford’s interactive SYNC system and is in more than 60 million cars.
by Lauren Krugel, The Canadian Press Posted Oct 20, 2012 1:07 am MDT Ottawa sends proposed Petronas-Progress deal back to drawing board CALGARY – The proposed $6 billion takeover of Canadian natural gas producer Progress (TSX:PRQ) by Malaysian state-owned energy giant Petronas has hit a potentially lethal snag.After reviewing the deal, Federal Industry Minister Christian Paradis has given it the thumbs down.“I can confirm that I have sent a notice letter to Petronas indicating that I am not satisfied that the proposed investment is likely to be of net benefit to Canada,” Paradis said in a statement issued late Friday night.The minister did not explain his decision, saying only that it was made after “a careful and thorough review of the proposed transaction.”Under the terms of the Investment Canada Act, Petronas now has up to 30 days to make any changes to the proposed deal and send it back to Ottawa for another review.“Canada has a long-standing reputation for welcoming foreign investment. The Government of Canada remains committed to maintaining an open climate for investment,” Paradis said at the end of his statement.At $6 billion, Petronas’ offer for Progress is substantial, but it’s eclipsed by the $15.1 billion China National Offshore Oil Co. is offering for Nexen (TSX:NXY).And observers had been looking for signals from the review of the Petronas deal about the government’s thinking on the more controversial deal to buy Nexen Inc.Both takeovers are by Asian state-owned players, are worth billions of dollars and sprang from joint-venture partnerships with Canadian firms, but the Chinese bid has stoked a great deal more political furor than the Malaysian one.“China comes with more baggage, as befits a great power,” said Gordon Houlden, director of the University of Alberta’s China Institute.Political scientist Wenran Jiang said the challenge for Ottawa will be to show consistency in how it applies the Investment Canada Act’s key net benefit test to foreign deals.“They will have to appear that they use the same set of rules to evaluate, rather than using different tailor-made rules,” said the senior fellow at the Asia Pacific Foundation of Canada.“They will have to show some seriousness as well as consistency.”Paradis has extended the review of the CNOOC-Nexen deal until mid-November. The reviews can be extended by further 30-day increments, with the buyer’s consent.Jiang said the perception of Chinese firms compared with other state-owned counterparts is unfair in many ways.“The Chinese state-owned companies are considered more menacing in a sense by some people than, say, a national oil company of Malaysia,” he said.“We need to figure out how do we treat China? Is this potentially treating China as an enemy? Or do you treat China as a business partner?”A year before their acquisition deal was announced, Progress and Petronas formed a partnership to jointly develop shale natural gas in northeastern B.C. and look at exporting the gas off the West Coast in liquid form.CNOOC and Nexen also had a pre-existing relationship. Last year, CNOOC scooped up Opti Canada, Nexen’s beleaguered minority partner in its troubled Long Lake oilsands project. The two firms also worked together in the Gulf of Mexico.While Nexen’s headquarters are in Calgary, its strategic importance to Canada is questionable. Only about 30 per cent of its forecasted daily production in 2012 is from its Canadian operations, with the vast majority coming from offshore platforms in the North Sea and elsewhere around the globe.“I don’t see these companies as being that material to the Canadian landscape,” said John Stephenson, portfolio manager at First Asset Investment Management in Toronto.“The government, I would suspect, would give its blessing to both deals…If you look at our oil and gas industry, we need hundreds of billions of dollars to develop the resource, to do the infrastructure. We just simply don’t have the ability to finance all of that here.”Canada’s spy agency raised a red flag on foreign investment by state-owned firms in its annual report earlier this year.Though CSIS didn’t name specific countries or companies it said certain state-owned enterprises have pursued what it called opaque agendas or received clandestine intelligence support for their pursuits in Canada.Prime Minister Stephen Harper has said the Nexen-CNOOC deal “raises a range of difficult policy questions.”At a news conference in Senegal last week, he said there’s a national security angle that factors into Canada’s relationship with China.“The relationship with China is important. At the same time it’s complex. It’s complex because the Chinese have obviously very different systems than we do — economic and political systems,” he said.“Of course, as you know, there’s a national-security dimension to this relationship, in fact to all of our activities, that we take very seriously.”While the NDP doesn’t have a position specifically on the Petronas-Progress takeover, it has raised a litany of national security, environmental and human rights concerns with the CNOOC deal.What the two deals have in common, though, is that the federal review process is too secretive and doesn’t set out clear enough guidelines on what constitutes a net benefit, said NDP natural resources critic Peter Julian in an interview.“There is a deplorable process in place. It’s a mess,” he said.“It’s difficult for Canadians to determine whether it’s in the best interest of the country because they haven’t put forward that clear definition of net benefit and a process that allows for public consultations.”
Trump welcomes some unions over others at the White House by Laurie Kellman, The Associated Press Posted May 7, 2017 6:14 am MDT Last Updated May 7, 2017 at 6:00 pm MDT AddThis Sharing ButtonsShare to TwitterTwitterShare to FacebookFacebookShare to RedditRedditShare to 電子郵件Email FILE – In this Feb. 2, 2017, file photo, President Donald Trump, flanked by then-Commerce Secretary-designate Wilbur Ross, left, and Harley Davidson President and CEO Matt Levatich, talks to media before a lunch meeting with Harley Davidson executives and union representatives in the Roosevelt Room of the White House in Washington. Trump says labor unions have an open door to his White House, but so far, he is holding it a little more ajar for some organizations than others.

(AP Photo/Carolyn Kaster, File) WASHINGTON – President Donald Trump says labour unions have an open door to his White House, but so far, he’s holding the door a little more ajar for some organizations than others.Trump has put out the welcome mat for the nation’s construction trades, with whom he’s had relationships during decades of building office towers and hotels. Also invited in have been auto, steel and coal workers who backed him during the 2016 election.But there’s been no White House invitation for other unions representing the sprawling but shrinking pool of 14.6 million workers who collectively bargain with employers in the labour movement.“You can tell Congress that America’s building trades and its president are very much united,” Trump told North America’s Building Trade Unions, even as he pledged in the same speech, “America’s labour leaders will always find an open door with Donald Trump.”But he has not courted all union leaders or advocated for all labour priorities. For example, he’s against a $15-an-hour minimum wage and has let linger a rule expanding overtime pay. Much like President Ronald Reagan did, Trump is not so much pursuing a labour agenda but one that appeals to those who share his “Buy American, Hire American” priorities and happen to be union members.“Trump is clearly working to be the blue collar president,” said F. Vincent Vernuccio, director of labour policy at the centre-right non-profit Mackinac Center for Public Policy in Michigan. “He’s trying to bring back the Reagan labour coalition and get the Blue Dog Democrats back.”The White House says the president is “open to meeting with various individuals and groups on how to improve the lives of all Americans.”But even among unions with most-favoured status, there’s some skepticism about whether he’s for workers or just the executives who hire them.Trump got some boos and hisses during his address to the building trades union. And Chuck Jones, president of United Steelworkers Local 1999, with whom Trump feuded, raises an eyebrow at the talk coming from the White House.“I don’t think from our perspective, he’s a friend of the working class person,” Jones said, noting that Trump’s tax plan would benefit the president himself, and that Trump campaigned on “getting rid” of a long-standing free trade deal with Canada and Mexico. “Trump always had some kind of relationship with the building trades. But for regular manufacturing? This is not a good time for working people.”The 2016 election suggests labour is fertile political ground for Trump. Exit polls showed he pulled within 8 percentage points of Democrat Hillary Clinton among union members — the best showing for any GOP nominee since Reagan in 1984.During his first 100 days, Trump has tried to appeal to those frustrated by seeing U.S. jobs go overseas. For example, he scrapped U.S. plans to participate in an Asia-Pacific trade pact and belittled the North American Free Trade Agreement, although he backed away from a campaign pledge to withdraw from it.He’s taken to Twitter to criticize American companies with plans to move some operations to other countries and threatened to tax any products they tried to sell in the U.S. He’s pushed a reluctant Republican-controlled Congress to pay for a $1 trillion rebuilding of the nation’s roads and bridges, and he’s green-lighted the Keystone XL pipeline.But while some unions have received the red carpet treatment, others have been largely ignored at the White House.Take teachers unions, traditional allies of Democrats. While Education Secretary Betsy DeVos joined Trump for White House sessions with teachers and other educators, neither of the two big teachers unions — the National Education Association and the American Federation of Teachers — was invited. DeVos did accept an invitation from AFT President Randi Weingarten to tour a school in Ohio.“Trump in New York was never involved in education. He was a blank slate on education,” Weingarten said.“The big test for him even on infrastructure is: Is he going to stop the Republicans in Congress from trying to take out the protections for prevailing wage,” she said. “Is he actually going to have enough money in there for projects?”Trump is picking and choosing among labour unions at a vulnerable time for the movement in American politics. Union membership declined 240,000 in one year to 10.7 per cent of the workforce in 2016, about half as much as when the Census Bureau began collecting such statistics in 1983.“There are some unions that, in fact, he has gone after. Teachers come to mind. Government employees come to mind,” said the AFL-CIO’s Richard Trumka, referring to the president’s pledges to close or slash spending for the Department of Education and efforts to shrink the federal workforce.Trump is starting with what he knows, and where labour is concerned, that means building trades go to the top of the list.“Did you ever think you’d see a president who knows how much concrete and rebar you can lay down in a single day?” he said at their conference last month. “We’re a nation of builders, and it was about time we had a builder in the White House.”This president, said Gary N. Chaison, a labour historian at Clark University, “knows very well from his old days working in the hotel industry in Manhattan that it’s important to get along with the construction unions.”
Concussions have become a hot-button topic all over the country. As science and medicine are continuing to discover how big an impact head injuries can have on someone’s day-to-day functions and future livelihood, sports organizations, and even Congress are beginning to take notice. Just this week, the NFL made its players aware of a new policy that will institute suspensions for its athletes for malicious helmet-to-helmet hits on a defenseless player. While once seen as a minor deterrent, the long-term effects associated with concussions have helped to paint a frightening portrait of what’s to come for our favorite athletes if they aren’t properly protected. Starting Monday, The Lantern will run a series on concussions beginning with part 1, prevention. Part 1 will be focusing on what can be done to better prepare oneself for avoiding a head injury, as well as offering a detailed look into why concussions are so hard to predict, who gets them, and what’s being done to protect athletes from having to worry about receiving one. Part 2, running Tuesday focuses on treatment. The story explains the dangers caused by head injuries both physically and mentally, what physicians and trainers look for in terms of symptoms, and what athletic trainers are doing to ensure that football players are ready to play after going through a concussion. Part 3, Second Impact Syndrome, focuses on a rare condition associated with a second head injury. SIS can lead to permanent disabilities and even death, but determining who’s susceptible to SIS is nearly impossible beforehand. Make sure to check out The Lantern in print or online for this exclusive look at concussions.

I hope that witnesses and those from that group who did not know how serious the attack was will now come forward.” DCI Noel McHugh, investigating, said: “Someone might see this video and remember that they witnessed this incident; you will see a female who is clearly shocked by what has happened and holds her hands up to her face. “You may have been part of the group and did not realise how seriously Desmond was hurt and that he has now died. That may prey on your mind. You can contact us and help us get justice. Desmond was an inoffensive man, a big man and character, who was out having a drink. The CCTV shows that he was senselessly attacked and he never stood a chance. Police have released the footage of the moment a 51-year-old man was attacked, apparently randomly, in Trafalgar Square, in a bid for witnesses.Desmond O’Beirne, 51, from Westminster was attacked outside the National Gallery at around 00:25 on Saturday, 3rd June 2017.He was approached by two men, who assaulted him, and then both calmly walked away.Mr O’Beirne, who was out for a drink with friends, fell into a vegetative state due to head trauma, and died in hospital in December last year.A woman appeared shocked by the attack, holding her hands up to her face – but the police have had no witnesses come forward yet.His death in December prompted a murder inquiry, and a serious crime reward of £20,000 is available to anyone providing vital information that leads to the arrest and conviction of the people responsible. “The events of Desmond’s attack precede the London Bridge Terrorists attacks which were in the following evening. So whilst there is a passage of time, people will remember where they were in London, and could remember this incident. I’m asking anyone who took any footage or selfies around that time in to contact us; take a look through your photos and see if you have something that can help us.” Desmond O’Beirne, 51, died in Dec ’17 after being assaulted in #TrafalgarSquare in June ’17. Do you have information that could help officers? https://t.co/QElsJuA57F pic.twitter.com/jYchrxpyln— Metropolitan Police (@metpoliceuk) April 9, 2018 His sister, Vivienne Folan, said: “My brother Desmond was hard working and larger than life. He was on a night out in Trafalgar Square when he was brutally and viciously attacked by two cowards who then calmly walked away and left him for dead.“As a direct result of this attack he suffered a traumatic brain injury and was left in a vegetative state. Desmond’s life was ended far too soon and our family is left devastated by his loss.“Unfortunately for Desmond, his attack happened less than 24 hours before the London Bridge/Borough Market terrorist attacks and I feel that possible witnesses may have focused their attentions on those events. I am appealing to members of the public who may have been in the Trafalgar Square area on the night and witnessed this assault to come forward to the police.
Read: Here are the details of exactly how to get a refund on your Garth Brooks tickets Read: What do you do now if you have a Garth Brooks ticket? THE GARTH BROOKS debacle is over. Probably.Barring a late twist, Ticketmaster will today begin refunding those who had bought tickets to the now-cancelled gigs, an operation that they say is “unprecedented”.A last-ditch attempt to save the gigs failed last night, when Dublin City Council refused to allow Aiken Promotions an uncontested High Court review, which would have allowed the gigs go ahead. Peter Aiken had said that he would only lodge the review if it was uncontested, but Dublin City Chief Executive Owen Keegan said that wasn’t going to happen.It is of course open to any individual or organisation who thinks otherwise to initiate judicial review proceedings and challenge the decision. I should state however, that any such proceedings will be vigorously defended by the City Council.If you bought your tickets over the phone or on-line the company is to automatically refund you, including the service charge, to the card used for the purchase on 15 July.Ticket holders who bought their passes at a Ticketmaster outlet will have to complete a refund form and return it to a Ticketmaster store. The form is available here.Read: No court intervention yet over Garth Brooks gigs after Aiken seeks legal advice
Chelsea midfielder Mateo Kovacic insists teammate Ruben Loftus-Cheek has set standard other midfielders at the club must follow, after his impressive hat-trick against BATE Borisov in the UEFA Europa League on Thursday night.In a team lacking a proven goalscorer apart from Eden Hazard, manager Maurizio Sarri has put pressure on his midfielders to provide more goals, which is an essential asset.Kovacic explained, according to Daily Mail:“We are playing very nice football, people like it, but we can do much better.”“The midfielders need to score more goals, me obviously, and Ruben scored three against BATE so he did well.”Lennon insists Celtic will seal its Europa League Manuel R. Medina – August 28, 2019 The team’s manager, Neil Lennon, believes his team is ready to take advantage of its 2-0 lead against AIK Stockholm and qualify to the group stage.“We need to play much better because we have a lot of quality in our team. I hope to score soon too, but in the end it’s important we play good football and push forward.”Meanwhile, Kovacic insists his only concern is surviving three matches a week and keeping Chelsea in title contention, amid talks about his future.Known as The Professor for his linguistic skills, the Croatia international concluded: “It’s good, I’m a little bit tired. I was not used to playing every three or four games and here it is very tough football. You can’t relax against anybody so it’s a little bit difficult but I really enjoy it.”“There is no pressure. Why? We like to play football and we are enjoying every moment, every training session, so it’s just joy, not pressure.”“We are still unbeaten but we need to look forward because we are not first in the league so we need to look ahead to get as many points as possible.”
Dan Cohen AUTHOR A row of World War II-era barracks at the former Fort Monmouth on the northern New Jersey coast that had been slated to be torn down instead may be converted into a cultural center.The Fort Monmouth Economic Revitalization Authority, which recently put the 4.4-acre site up for sale, is looking for an entity that is interested in turning the property into a cultural center for art, music, entertainment or a museum, reported the Asbury Park Press. The property includes Soldiers Park, which a new landowner would be required to preserve. Alternatively, a buyer could convey the park to a public entity to maintain. The two-story wood frame buildings, located in the Eatontown portion of the property, were built in 1942. The Army converted them into administrative space following the war. A small portion of the site sits in Oceanport, but the LRA intends to work with the two municipalities to adjust the boundary so that it lies entirely in Eatontown.One entity has expressed interest so far, said Eatontown Mayor Dennis Connelly. “It will be a good addition to town,” Connelly said.
A housewife allegedly committed suicide by setting herself afire at Sholakandi village in Brahmanbaria’s Sarail upazila on Sunday, reports UNB. The deceased was identified as Shima Rani Gope, 28, wife of Nantu Gope of Ajmeriganj upazila in Habiganj district.Mafiz Uddin Bhuiya, officer-in-charge of Sarail police station, said Shima came to visit her father’s house at Sholakandi village few days ago. Shima set herself afire after pouring kerosene in a toilet of the house around 1:15pm, he said. Her charred body was recovered from the toilet after breaking open the door.However, the reason behind her suicide could not be ascertained yet.

Wang describes the ways in which the researchers addressed these challenges. “To characterize ferroelectricity at nanoscale, the most widely used technique is called piezoresponse force microscopy, or PFM, which utilizes the converse piezoelectric effect.” (In the converse piezoelectric effect, materials become strained when an electric field is applied.) This is a technique that can be implemented using a commercially available atomic force microscope (AFM), in which AC bias can be applied to the AFM probe that serves as a moving electrode on top of the sample. The resulting AC electric field will cause the periodic oscillation of the ferroelectric sample due to this converse piezoelectric effect. The oscillation signal can then be detected by the AFM. “The amplitude of the oscillation represents the piezoelectric response that is proportional to the ferroelectric polarization,” Wang explains, “while the phase of the oscillation represents the direction of the polarization.” In their study, the scientists employed a state-of-the-art approach known as Dual AC Resonance Tracking (DART) PFM developed by Asylum Research to amplify the piezoelectric response by taking advantage of the resonance enhancement. The scientists are planning to study the pyroelectric properties of CuInP2S6 at its two-dimensional limit and apply their findings to developing energy harvesting devices. To that end, he adds, because mechanically exfoliated 2D materials are usually small and unsuitable for device applications, chemical vapor deposition growth of atomically thin CuInP2S6 is under development.”Ferroelectric properties are also very interesting for solar cell applications because of efficient ferroelectric polarization-driven carrier separation,” Liu concludes, “so 2D ferroelectricity-based solar cells could be very interesting, In its liquid phase, 2D ferroelectric CuInP2S6 could be easily hybridized with semiconductor 2D or organic materials – and a solar cell based on these hybrids would be very promising.” Figure 5 | Electric characterization of the vdW CIPS/Si diode.

(Phys.org)—Optoelectronic devices that combine electronics and photonics are incorporating two-dimensional (2D) materials for a range of applications. At the same time, cooperative phenomena – in which a system’s individual components appear to act as a single entity rather than independently – have yet to be widely investigated, an important example being ferroelectricity (spontaneous electric polarization that can be reversed by an electric field) in the 2D limit. Recently, however, scientists at Nanyang Technological University, Singapore have demonstrated room-temperature out-of-plane ferroelectricity (that is, orthogonal to the 2D material) in 2D CuInP2S6 (copper indium thiophosphate) with a ~320 K transition temperature, as well as switchable polarization in 4 nm CuInP2S6 flakes. The researchers state that their findings create the possibility of sensors, actuators, non-volatile memory devices, various van der Waals heterostructures (devices made from layers of dissimilar 2D crystals in which forces are based on molecular attraction or repulsion rather than covalent or ionic bonds), and other novel applications based on 2D ferroelectricity. Finally, in demonstrating a non-volatile memory device with an on/off ratio of ~100 in a CuInP2S6/Si ferroelectric diode, Liu notes that this investigation is just a preliminary demonstration of the possible applications of the 2D ferroelectric material. “A lot of work needs to be done to fully understand the transport mechanisms and how it is coupled to the ferroelectric switching,” he acknowledges. Tunable and mechanically robust ferroelectric ionic plastic crystals Prof. Zheng Liu and Prof. Junling Wang discussed the challenges that they and their colleagues encountered in conducting their study published in Nature Communications. “With reduced dimension, ferroelectricity – namely, long-range electric-dipole order – becomes fragile owing to the depolarization field that is opposing its own electric polarization,” Liu tells Phys.org. “The depolarization field inherently arises in ferroelectric materials due to the imperfect screening of bound charges,” that is, those bound to molecules and so cannot move in response to an external electromagnetic force. The difficulty lies in maintaining a precise geometry, Liu adds, because when the ferroelectric material’s thickness is reduced to its two-dimensional limit, the depolarization field can increase by orders of magnitude. At that point, the depolarization field may place the ferroelectric material into a paraelectric state, the result being disordered electric dipoles with a temporary polarization only when in the presence of an electric field. Therefore, the electrical boundary conditions are extremely important when exploring ferroelectricity at the material’s 2D limit. Moreover, he adds, reporting the experimental observation of switchable polarization in CuInP2S6 films down to 4 nm at room temperature, thickness reduction will greatly weaken the out-of-plane ferroelectric polarization. “This makes characterization of the ferroelectricity very difficult. Moreover, the large ionic conductivity of this material makes the polarization switching quite challenging. We therefore had to choose a small electric field that is just above the coercive field to avoid unwanted ionic motion.”Other concerns include demonstrating the potential of this 2D ferroelectric material by preparing a van der Waals ferroelectric diode formed by CuInP2S6/Si heterostructure. “In the case of CuInP2S6, the chemical composition and phase stability also play a role in stabilizing ferroelectric states – and in the 2D limit, it is difficult to determine the ferroelectricity with traditional methods, such as the time-dependent ferroelectric hysteresis loop measurement, due to large leakage current,” lead author Liu Fucai points out. Regarding potential, he explains that due to the relatively large band gap and thus weak light absorption, few-layer CuInP2S6 appears almost transparent on silicon (Si) substrate. “This situation makes the fabrication of the van der Waals heterostructure quite challenging during the lithography process.” Figure 3 | Ferroelectric polarization switching by PFM for CIPS flakes with different thicknesses.

Thus, the small ferroelectric polarization of the ultrathin CuInP2S6 flakes can still be detected by the AFM, as the signal has been amplified by orders of magnitude. This advanced PFM technique helps us to image the fine domain structure with nanometer lateral resolution and picometer vertical resolution, and thereby realize local ferroelectric switching using an AFM probe.”The paper discusses novel applications, including sensors, actuators, non-volatile memory devices, and various van der Waals heterostructures based on 2D ferroelectricity. “By virtue of the piezoelectric effect, ferroelectric materials always have the piezoelectric and pyroelectric properties that allow the use of atomically-thin CuInP2S6 as a strain sensor with high flexibility, such as electric skin monitoring human body motion,” Liu tells Phys.org. “By using the pyroelectric effect, 2D CuInP2S6 could also be used for thermal energy harvesting, and as we know, commercially available ferroelectric random access memory, or FeRAM” – random-access memory similar to DRAM – “with fast writing speed and low-power consumption, but with destructive readout could be improved by employing a ferroelectric diode to achieve non-destructive readout of the information. Considering the quasi-freestanding nature of 2D materials, ferroelectric diodes, or even ferroelectric tunnel junctions with an atomically thin ferroelectric layer may have a much higher ON/OFF ratio, providing the possibility of high-density ferroelectric memories with non-destructive readout.”Regarding the relationship between, and potential applications deriving from, ferro- and piezoelectric effects and van der Waals heterostructure interactions, Liu notes that vertically stacking of different 2D materials with van der Waals force have revealed unusual properties and have been investigated for the application of tunneling transistors, light emitting diodes, and light harvesting devices. “Incorporating ferroelectricity to the van der Waals heterostructure could demonstrate new functionality, such as ferroelectric field transistors and optoelectronic memory, by combining CuInP2S6 with 2D semiconductors.” © 2016 Phys.org

Despite declarations from the executive branch that the Costa Rican government will not pursue geothermal electricity development in national parks, the office of governing Citizen Action Party (PAC) legislator Ottón Solís is working on a bill to allow it in three volcanic protected areas.The bill would address conservationists’ concerns over exploiting Rincón de la Vieja, Tenorio and Arenal national parks by developing geothermal capacity in the parks in conjunction with the National System of Conservation Areas, or SINAC, in a way that conforms to the conservation goals of the protected areas, said Rodolfo Cordero, an aide to lawmaker Solís.The bill would require the Costa Rica Electricity Institute, or ICE – which would develop the volcano’s geothermal electricity capacity – to compensate land used for the projects with land outside the parks.The land would not be sequestered by ICE as initially proposed, but rather remain in the hands of the Costa Rica National Park Service, which would assure that the projects continue to protect habitat.Conservationists have been particularly concerned about the sequestration of parkland for the precedent it would set for the entire national park system.The new plan would substitute a bill that was shelved in May 2014 amid an outcry by conservationists over plans by ICE to sequester 1,000 hectares of land inside Rincón de la Vieja National Park in the northwestern province of Guanacaste, which as part of the Guanacaste Conservation Area was declared a UNESCO World Heritage Site in 1999. Costa Rica lawmaker and Citizen Action Party co-founder Ottón Solis in a 2010 file photo. Mayela López/AFPPAC divisions?Interestingly, the new bill would run counter to declarations by Costa Rica’s President Luis Guillermo Solís that geothermal electricity generation in national parks is not currently on the table.The plan also would run counter to a letter written last April by Environment Vice Minister Irene Cañas to Kishore Rao, then-director of UNESCO’s World Heritage Center, in response to Roa’s letter of concern over the plan to exploit Rincón de la Vieja.In the missive, Cañas said the bill permitting exploitation of the conservation area was conceived under the previous administration, and the Solís government gives no priority to presenting it during extraordinary session – when the executive branch sets the legislative agenda – beginning in December and running through April.“Also, the president of the republic has repeatedly and publicly indicated that his administration has no interest in promoting geothermic exploitation in national parks,” Cañas said.

Costa Rica’s Rincón de la Vieja National Park. Google MapsUgalde led the effort to scotch the bill based on concerns that the sequestration of land inside Rincón de la Vieja would pose an existential threat to the entire park service system by setting a precedent leading to similar moves inside other national parks.Ugalde also complained that he had lobbied private foundations in the 1980s to fund the purchase of land in Rincón de la Vieja National Park with promises that the land would be protected in perpetuity.

LISTEN: Michael Floyd, Cardinals wide receiver Top Stories Comments Share Former Cardinals kicker Phil Dawson retires At 6-foot-3 and 225-pounds with good speed, Floyd certainly has the look of a go-to receiver.But the production hasn’t quite been there, and Floyd’s failure to establish himself led to some speculation that the Cardinals might be looking to trade him. The wideout was aware of the rumors, but said the chatter did not effect him.“Being a player, you can’t let it bother you,” he said. “I think, mentally, if you let it get to you a lot of things can happen, negativity.”Instead, Floyd said he just works even harder, controlling what he can control. If all goes according to plan, that will lead to him having a big 2015. For Floyd, who said he has plenty he would like to accomplish during his career, that would be a welcome situation.“I just always, since I was young, (wanted) to be the best player that I could possibly be, and putting in the work each and every day,” he said. “But also learning at the same time. Larry has a lot under his belt, and you can’t do nothing but learn from someone like that.“Watching other guys around the league, too, big guys like me, you can learn a lot from them because they experience a lot more and being a vet guy and having that experience, (me) being four years in you can take that into your own game and kind of implement onto the field.” – / 16 “Because they want me to be successful and they count on me and they expect me to make plays when they come my way, and I expect myself to make them, too.”You don’t have to look too hard to find reasons that are beyond Floyd’s control to help explain his down year. The team’s issues at quarterback, where injuries ravaged the position, were a factor. Carson Palmer, Drew Stanton, Ryan Lindley and Logan Thomas combined to throw 97 passes Floyd’s way, with Palmer and Lindley being the only two to complete more than half of them. Stanton, who threw a team-high 45 passes to No. 15, connected on just 40 percent of the throws. Then again, as anyone who watched the Cardinals last year would tell you, there were also certainly times where it seemed as though Floyd could have made a play only to come up short. Now 25 and entering his fourth NFL season after being taken 13th overall in the 2012 NFL Draft, it would seem to be the right time for the former Notre Dame star to put it all together and become the player Arizona thought he would be, possibly supplanting legend and future Hall of Famer Larry Fitzgerald as the team’s top option in the passing game. Your browser does not support the audio element. The 5: Takeaways from the Coyotes’ introduction of Alex Meruelo Michael Floyd knows his 2014 season was not as good as his 2013 campaign. He caught 18 fewer passes, gained 200 fewer yards and, while he scored one more touchdown, his year was generally viewed as a disappointment. “I think last year wasn’t as good as my first year with [Bruce Arians],” he told Bickley and Marotta on Arizona Sports 98.7 FM Tuesday. “A lot of things come into play with that, but I usually look at myself individually and I think some of the stuff that I did was inconsistent, but I heard B.A. say that and I take that as a challenge to myself to be a better player and make plays for this offense and this team.

are seen throughout the media GE is not alone in latching onto the current trendiness of soft-core feminismbrands like CoverGirl and GoldieBlox have recently put out well-received empowering spots But unlike GE those brands products are specifically for girls and women so their logic is clear GEs motivations are a bit more complicated What does the company stand to gain by showcasing working mothersand why involve daughters In large part its a reflection of the changing workforce "Just in the past year or so" says Kelley Skoloda a partner at the marketing firm Ketchum "youve heard a lot

Comes to America” on Twitter and culture a physicist and eight-term Democratic member of Congresshas been named the new CEO of AAAS(which publishes ScienceInsider) He will succeed Alan Leshner a neuroscientist who is stepping down this winter after leading AAAS since 2001 Holt 66 has represented a New Jersey district since 1999 but in February announced he would not seek another term Although not known for sponsoring legislation Holt has earned kudos from both Republican and Democrat colleagues for being an effective behind-the-scenes advocate for additional funding for research and science education He was part of an unofficial bipartisan “physics caucus” in Congress that at its peak totaled three members who held physics PhDs Holt has a long political pedigree His father was a US senator from West Virginia in the 1930s and his mother was West Virginia’s secretary of state He was elected to Congress in 1998 after spending a decade at the Department of Energy’s Princeton Plasma Physics Laboratory A former physics teacher at Swarthmore College he credits the long-running AAAS Science and Technology Fellowship program which allowed him to spend a year on Capitol Hill for piquing his interest in politics “I will continue to work on trying to bring more scientific thinking to public policy and to American society in general” he told ScienceInsider after announcing his retirement from Congress “Those are ongoing interests of mine I think it’s important to maintain freedom of inquiry and to make sure that we have support not just for research but also for scientific communication” Holt was a vocal—but often lone—advocate in Congress for reviving the Office of Technology Assessment a well-regarded in-house think tank for legislators that Congress abolished when Republicans took control in 1995 He admitted that it was an uphill battle but felt the fight was worth waging “I would say that most members of Congress value science and respect scientists” he told ScienceInsider in February “But I don’t see more scientific thinking evidence-based critical thinking” This fall Holt made an eloquent pitch for the importance of science to society whenthe American Academy of Arts & Sciences rolled out a reporturging the government to commit to steady long-term increases in research funding He began by asking Americans “to banish the pessimism that is dominating our public policy on this issue and so many others” Then he sketched a picture of where the country is and where he thinks it needs to be “Why hasn’t Congress paid more attention to the critical point we’ve reached I’m not sure But it may be because we’ve taken it for granted that America’s leadership will continue as it has for a couple of centuries The sky seemed to be the limit for what we could do And after the Apollo flights we even broke through the sky “This success has continued in some respects enough to make some members of Congress complacent But if you look at transportation energy and every other sectors the transformative breakthroughs that we thought we were heading toward 20 or 30 years ago have not materialized “What we need at this point is a return to America’s traditional optimism I don’t mean empty technological optimism that technology will solve all of our social problems But I do mean optimism that we can increase economic opportunity and personal growth and create jobs and grow to overcome our short-term problems That’s what we have always done” Leshner who was a senior administrator at the National Institutes of Health and the National Science Foundation before coming to AAAS said that “Rush Holt is an ideal choice to lead AAAS and Science into the future His expertise experience and commitment to science and to public service are sure to greatly enhance the association’s impact in all domains” The American Association for the Advancement of Science (AAAS) founded in 1848 is the world’s largest general

editor in charge of economics and business She has written this weeks cover story on General Motors CEO Mary Barra To read the full post you need to be a subscriber Its not too late to sign up here DonQuixotic asks Rana what are your thoughts on the current tech bubble and overvaluing of tech companies Are we inevitably headed towards another tech market crash similar to the dot-com bubble of the early 2000’s Is there anything we can do to mitigate the damage or prevent it I think tech stocks are definitely over-valued; aside from commercial real estate and certain lower grade corporate bonds they are probably the frothiest part of the market right now The model of many Silicon Valley consumer oriented firms is to spend as much money grabbing as much market share as possible the idea being that theyll figure out how to make money later I think a fair number of them wont (although there will still be some big winners in each category) The problem is that when you bet on tech particularly in the early portion of a new business cycle its hard to pick the winners thats why Warren Buffett tells me he rarely bets on tech In terms of mitigating damage Id stay indexed in a diverse mix of big US firms dont focus in too much on one sector nflfoghorn asks If the economy is much better and unemployment – if not more prevalent – has held steady why do so many people think the president is doing a poor job handling it especially since we went through a severe recession Its a great question and as I write in my column this week I think the answer is that people dont feel like we are in a recovery because only a fraction of the middle class jobs have come back (most job creation in this recovery has been in the low pay or very high pay sectors there still arent enough jobs in the middle which is where most Americans are) Until middle class job creation is more robust and income starts to rise I expect poll numbers will stay low nflfoghorn asks Hello Rana – What do you think Mrs Barra’s impact has been on GM’s culture Has she been able to put her stamp on a company notorious for doing things on the cheap and endangering lives What do her peers at Ford Chrysler/Fiat etal think of her leadership As youll read in this weeks TIME cover reviews on Marys handling of the crisis have been good but reviews about her overall management style are mixed some folks that I really respect like Bob Lutz think she may not be able to be confrontational enough to change GM Others say she has an iron fist in a velvet glove My own sense is that shes slowly but surely making changes but that in a company this size its going to be a multi-year process and shell need to bring in disruptors from the outside as well if shes going to effect real change deconstructiva asks Rana what’s your take on raising the minimum wage I think it should be raised if only for two reasons – (1) It never kept pace with inflation else it could in the 20’s or least much higher (2) With current minimum wage many people at that level who are raising families have to rely on govt assistance like food stamps and I think no one working full time should ever have to rely on food stamps Its interesting that people who are against raising the minimum wage often dont address the fact that in many states average hourly wages are already way above the national minimum and it doesnt destroy jobs (the common argument of those against a national raise) My feeling is that we could and should raise the minimum wage but that we have to do many other things at the same time most importantly revamp K-12 education and make sure educators are better connected with job creators to make sure that higher wages dont result in job losses to other countries or to technology yogi asks RF do you think the recent changes to corporate tax rules will stem the tide of corporate inversions If not do you know of a potential better way or will it simply take customers turning away from the companies that invert to cause others not to I think the Treasurys new rules are a good start in large part because they lay down a political market its not OK for US firms that have benefitted from US taxpayer investment (in the form of education infrastructure state R & D etc) to eschew paying their fair share of taxes That said we need to go a lot farther as I wrote in this column on tax inversions we should also rethink and revamp our tax code and stop rewarding the use of debt over equity which is often what fuels these deals DonQuixotic asks Rana how damaging will collapse of China’s housing market be to the global economy Once it’s come and gone how long will it take China to recover and what impacts do you believe it will have on the global market and global trade once they do How do you think it will reshape it Fascinating question and probably the most important question in the global economy today China is already suffering a major economic slow down The government says the economy is growing around 7 %; I think its more like 4 % Either way its clear that theres a crisis in middle class job creation there are more unemployed college grads in China than lower end workers All this connects to the real estate bubble; until China revamps an economy built on cheap labor and cheap capital its growth will remain muted which is one reason the global economy isnt growing faster This isnt a Lehman type situation Chinas banking sector has a lot of bad real estate loans on the books but its a closed mostly government run system so the bad debt itself wont necessarily ricochet around the globe But if unemployment grows it could cause social unrest and if the government were to be destabilized that would be a major shock to the global economy Right now the Chinese leadership is trying to consolidate power and (hopefully) launch a new series of economic reforms Hopefully this will happen But even if it does were looking at a transition that will take a decade or more Chinese double-digit growth is definitely a thing of the past deconstructiva asks Rana where do you think the next big global currency crisis will come from Europe grabbed most of the attention in recent years but might someone take their turn next We remember the big Asian currency woes in past years and Russia’s default in the 90’s caused chaos …and that infamous LTCM fund back then held a LOT of Russian debt only we didn’t know that until THEY crashed and burned Indeed might the next big currency crisis involve rogue trading and speculation as much if not more than said future country’s own economic woes Great question I dont think the European debt crisis is over we could still see defaults flair up But the issue Im most worried about right now is the assumption that the dollar will stay strong forever For starters a stronger dollar isnt an unadulterated good it acts as a kind of dampener on credit and lending in the global economy since so much business is done in dollars (and right now you could argue we need more lending in certain sectors) But also its based on the assumption that the US markets and economy will remain strong (or at least stronger than many other parts of the world) indefinitely As interest rates rise probably in the second half of next year you could see a lot of volatility as the tide of easy money goes out and we see who has been swimming without their shorts PaulDirks asksYou recently wrote “When the majority of people dont have more money they cant spend more and companies cant create more jobs higher up the food chain” But isn’t this a classic prisoners dilemma for managers Every company is doing it’s best to hold it’s own costs down but no one can unilaterally raise wages without their competitors undercutting them on price That’s why a minimum wage adjustment makes sense It lowers all boats slightly but it breaks the logjam that holds everyone back What will it take before the USCOC types actually understand that it’s in their own interest to do something about wages Youve summed up the problem well As I say in one of the answers above I dont think a minimum wage hike would hurt growth but I also dont see the political will to push it through in the next couple of years since were heading into an election cycle Whats interesting is that some enlightened companies are actually trying to create higher wage workers (which they correctly realize are their future employees and customers) themselves IBM for example has started a series of high schools to churn out kids who can walk straight into 50K a year jobs See my cover on that here Sue_asks Rana in your story on the 3% economy (which was very good btw) you mention student loans/debt as the next crisis point As a parent with one child in college and another going next year I have a very personal interest in this issue My daughters are going to graduate college with mortgage-level debt hanging over their heads And not just my daughters but an entire generation of students This is going to have far-reaching effects on the economy just for example home-buying and potential small-business startups Who can do either when they’ve already got such a daunting debt load It also impacts parents who want to help their kids pay off (or at least down) some of that debt We put off things like trips new car purchases home renovations (or buying new homes for ourselves) to help the kids My question has two parts 1) What needs to be done to fix this problem I know Sen Warren has some ideas but what other options are there 2) What are the chances that anything will get done Is there any widespread sense that this is a problem and that it needs to get fixed As the mother of two kids myself aged 8 and 12 Im also extremely concerned about this I make a good living but am struggling to save the 70K or so each of them will need to attend a private university debt free It boggles the mind to think about how average Americans on a median wage can ever imagine doing this Aside from Senator Warrens ideas which I think are great this is one area where some financial innovation could help One of the major problems with the student loan market is that its fixed and static there are two set rates for loans they are high and they cant be refinanced We should change that (a la Warrens ideas) but we should also encourage more innovation in the student lending market For example Ive spoken to internet entrepreneurs who are creating "crowd funding" type models for student loans where alumnae from individual colleges (who have a better sense of the opportunities and risks associated with various degrees from particular schools) can loan money to graduates themselves at lower rates Theres a company called SoFi thats doing this successfully I also imagine that companies themselves will get more involved in sponsoring talented students paying their way through school in exchange for a set number of years of employment with the firm at the end of a degree One could argue this is a kind of paid indentured servitude But in lieu of more government action (which I would of course like to see) its not a bad option for some students particularly in high pay fields like technology deconstructiva asks Rana we still have chronic long-term unemployment in our recovery so how do you think we should best address that so that everyone – literally – who wants to work can go back to work (As one of those long-term unemployed alas I definitely have interest in fixing this but I digress) The major caveat as we know is that Congress is doing almost nothing on this thanks to the GOP and the Tea Party’s obstruction So given that what can we do I’d rather face the classic economic “problem” of wage inflation from full employment than to face mass unemployment which is a problem in ANY sane economic model A couple of years ago I interviewed Warren Buffett and we talked about this question
