Chiefs stay in F4 hunt

But nonetheless, this win gives us hope.” The Chiefs shot 50 percent from the field as five other players posted double digit outputs, including Zach Nicholls and Lervin Flores, who chipped in 13 points and 12 points, respectively.“We expected this performance from Kent (Salado) because he’s really matured,” said Codiñera, whose team took an early double-digit lead and never looked back. “We had a good start and the support group also responded.”The win gave the Chiefs a lifeline in the race for the two remaining Final Four spots. As it stands, Jose Rizal holds pole position with a 9-7 record with Letran (8-7) and San Sebastian (7-7) also in the running.While Codiñera knows their fate is no longer in their hands, the Arellano coach is hopeful the other teams slip.“We just have to win our remaining games and hope for the best,” he said. “If we end up with nine (wins), we might finish third especially with the win over the other rule.

Operating room doctors lament attacks on personalized cloth caps

first_imgRetired anesthetist Dr. Glenn Gibson believes he was an early trendsetter in slipping on brightly coloured cloth caps before heading into the operating room.So he was a bit disappointed when some hospitals started to ban the cloth protective headwear, which allow doctors to show a little personality.“I like cloth OR caps. I got tired of wearing the plain green ones, so about 25 years ago I started making my own … with ridiculous colours and designs that nobody would buy,” said Gibson, who estimates he had about four dozen at one point.A recent edition of the Journal of the American College of Surgeons suggests that freshly laundered cloth operating room hats are better at controlling microbial shed than the disposal shower-cap style “bouffant” hats that many hospitals have been forcing staff to wear in the name of infection control.For many, the publication was cause for celebration.Some operating room staff have long complained that the disposable bouffant caps are hot, make it hard to hear people, and reduce the little bit of personality available in a place where all staff wear the same scrubs.Many also grumbled that the evidence that resulted in banning cloth hats was weak and that disposable bouffant caps create a lot of garbage.“The cloth cap ban did generate some debate, some of which centred on evidence-based medicine (or lack of it) and some of which was likely vanity driven,” said cloth cap fan Dr. Lesley Barron, a general surgeon in Georgetown, Ont.Some have argued that personalized caps — featuring cartoons, favourite team logos, or festive scenes —can also improve patient care by decreasing pre-operative anxiety.“You can chat about your hat while (the patients) are going off to sleep,” said Barron.But Molly Blake, president of Infection Prevention and Control Canada, is not quite as enthusiastic. She highlighted the main caveat of the study: that reusable cloth caps need to be regularly washed.“The safe and appropriate management of scrubs is already challenging … you may have seen health-care workers wearing scrubs — and cloth skull caps — travelling throughout hospitals and then wearing the same into the ORs,” Blake said, adding that the cleaning methods discussed in the study were not “normal practice” in her experience.Blake also suggested the findings of the study should be replicated in an experiment with a bigger sample size before endorsing cloth caps.But not all hospitals banned cloth hats in the first place.“To be honest, we did not give a great deal of consideration to banning cloth hats because we felt the evidence wasn’t strong enough to support it,” said Jason Hann, director of surgical and critical care services at the Children’s Hospital of Eastern Ontario.“Of course, we have conditions that must be met in order to ensure patient safety, but this has not been a problem.”While an individual hospital’s infection control policy might be explicit, the fashion rules about operating room headwear are often more subtle: some feel there are gendered norms and silent expectations.“The culture is definitely (cloth) skull caps for boys, bouffants for women,” said Barron.Though confessing that she finds cloth caps “ugly,” Barron does admit that they give more room for hair, prevent overheating, and are less likely to create “OR head” — a condition similar to “bed head”. While women with short hair often wear cloth caps in the operating room, in doing so, they risk gender misidentification.Family doctor and anesthetist Dr. Annie Lu owns several cloth caps with Asian-styled dragon prints, but said, “when I wear them, I get mistaken for a guy by patients sometimes. There seems to be some notion of gender based on the style or design of the cap.”And though a medical student might be eager to show off a little personality, tradition dictates otherwise.“It would seem pretentious of a med student to already have custom cloth hats,” warned Dr. Kyle Sue, a family doctor in Arviat, Nunavut. Some surgeons believe that medical students should only wear cloth hats after they have matched to a surgical specialty for their residency.Most operating room staff who do wear cloth hats get them from a co-worker who makes them.After volunteering in a hospital in the Volta region of Ghana, Montreal nurse Julia Garland decided to start fundraising with handmade cloth hats and has raised over $10,000 to date, enough to fund three separate yearlong scholarships for Ghanaian nurses.Beyond the print design, there are other ways the hats can be customized: built-in sweatbands can be added, a little extra room for those with ponytails, and reversible fabrics for the indecisive.Gibson is glad he managed to avoid a cloth cap ban during his career.“I would have been sad, as I felt the crazy designs on my hats were very helpful with children,” he said.“I was up to a total of 48 different hats. Every morning it was a tough decision which one to wear, depending on whether the patients were adults or children.”— Dr. Sarah Giles is a family/emergency room doctor and a fellow in global journalism at the Munk School of Global Affairs at the University of Toronto.last_img read more

TV technology provider KIT Digital is set to file

first_imgTV technology provider KIT Digital is set to file for bankruptcy, in a move to recapitalise the company put its core operating into newly formed group called Piksel.The firm said that as part of its reorganisation plan its three largest shareholders had agreed to file for Chapter 11 bankruptcy in the US – a move that allows firms to reorganise their business affairs and assets and is generally filed by corporations that need time to restructure their debts.Through the plan, KIT Digital said that it “expects to be in a position to pay all vendors, suppliers and other holders of valid pre-petition claims.” It said that the chapter 11 would only impact the “non-operating parent company Kit Digital” and that its subsidiaries, including Ioko 365, Polymedia, Kewego, Multicast and Megahertz will not be impacted. These will make up the new entity, Piksel.“We are pleased to announce this comprehensive solution that will provide KIT with relief from the financial, legal, and regulatory issues currently encumbering it,” said non-executive chairman of the KIT Digital board, William V. Russell.“The plan allows all shareholders the opportunity to participate in the future growth of the company and at the same time it will complete the company’s restructuring by strengthening the balance sheet and positioning it for profitable growth.”Interim chief executive officer Peter Heiland added: “By moving the core businesses forward together unburdened by the issues currently plaguing the corporate parent, our customers and products can once again become the sole focus of this exciting business.”KIT’s bankruptcy filing is expected to happen by April 24.last_img read more

The photo above shows a queue of people waiting at

first_imgThe photo above shows a queue of people waiting at a currency exchange booth in Montevideo, Uruguay. Only a year ago, such queues were uncommon, but now they exist, literally at every such booth, at every hour of the day. Are Uruguayans suddenly becoming spendthrifts who need repeated daily infusions of cash to get through each day? No; and in fact, very few of those in the queues are Uruguayan. They are Argentines. The reason these people are in a foreign country, trying to extract a foreign currency from the exchanges is that the Argentine currency has been devalued dramatically through inflation and is on the way to further inflation. Argentines have understandably sought to bypass the peso in favor of the US dollar, in order to keep from losing their purchasing power any more rapidly than necessary. In response, the government of President Cristina Fernández de Kirchner has imposed a “dollar clamp,” which is intended to limit the use of dollars by Argentines. Not surprisingly, Argentines are trying everything they can think of to circumvent that dollar clamp, including taking the one-hour Buquebus ride across the Rio de la Plata to Uruguay to extract US dollars from their peso-based Argentine credit cards, for “spending money.” The day-tripper “tourism” has become so extreme that Cristina Fernández has passed a new credit-card limit to Argentines. An Argentine overseas now may extract only US $800 per month. More pointedly, if the destination is a neighbouring country (read: Uruguay), the limit is $100 every three months. No need to question whether $100 every three months would actually pay for the expenses of a visit across the river – there has been no attempt to disguise the measure as anything but a currency control. The purpose is that, as the monetary collapse completes its downward spiral, the sheep are penned in ever more firmly, to ensure that the final shearing may be as productive as possible. As one Argentine commented to me recently, “After October, there will be no more new Versace for Cristina. They have to take all they can from us now.” That’s a reference to both Mrs. Fernández’s rather extravagant wardrobe expenditures and the expected outcome of the October elections. But surely, all the above are the machinations of a south-of-the-equator, tin-pot dictatorship and have little relevance to the First World. Not so. Argentina provides us with a very useful lesson. Over the decades, its politicians have repeatedly collapsed the economy through the classic progression of governmental overspending/creation of massive debt/dramatic inflation/currency controls. Historically, this progression has always led to an eventual collapse of the economic system (wherever and whenever it has occurred, not just in Argentina). We can therefore observe the developments as they occur in Argentina and project out as to what may be on the way in the First World. The First World countries have most certainly reached the point of having top-heavy governments that have enormous appetites for funding, and are expanding those appetites dramatically at a time when they should be cutting back dramatically. As governments in this situation always do, they have turned to indebtedness as a solution, in order to prolong the current trend as long as possible. In order to cope with the debt, massive money printing is undertaken, which leads directly to inflation. Inflation leads to an outflow of wealth from the country in question, which is then addressed through currency controls and protective tariffs. Argentina is in the last stage of this progression and is poised to go over the edge. Its last production of this economic stage play was in 2001, and when the collapse came, the situation in Buenos Aires became so volatile that Argentina went through five presidents in just three weeks. The US, on the other hand, has reached the point in its money-printing scheme that it is now buying $85 billion per month in Treasury bonds and mortgage-backed securities and is committed to continuing to do so “until conditions improve.” This is equivalent to a railroad train approaching the cliff of the Grand Canyon whilst a crew of workers shovel dirt into the canyon to fill it in, in time to prevent a train wreck. If the classic progression continues as it does historically, we can anticipate dramatic inflation, followed by currency controls and protective tariffs in the US and other First World countries. As yet, there is little on the news regarding protective tariffs, but currency controls are very much in the works. Many have been implemented, and more are to come. At this point, anyone whose primary address is in a First World country might wish to ask the question, “Is there a dollar clamp in my future? Will my government soon be at the stage that my national currency will be inflating dramatically; and if I choose to divest myself of it, shall I find that I am unable to do so, as a result of hastily implemented government controls?” The answer is unequivocally “Yes.” Governments are in the habit of claiming that their first priority is the safety and well-being of their citizens. However, when a citizen of any country chooses to exit from the relationship, either physically or monetarily, governments have a nasty habit of turning, suddenly and forcefully, vindictive. For those who have a difficult time getting their heads around this fact, the following may be useful in providing a very real perspective. Picture a situation in which you are married and have reached the decision that your spouse’s wasteful spending is crippling you personally. You then request a divorce. You make plans for splitting up the bank accounts and personal possessions and are hit with an injunction from your spouse’s attorneys. You say, “But these possessions are mine. This money is mine. I worked with the sweat of my brow to earn them.” The attorneys then advise, “That’s not the way we see it. We regard them as community property, and we’re prepared to negotiate with you as to how much we will allow you to walk away with.” The above situation is virtually the same as one in which you choose to split the sheets with your government, should you choose to do so at a time when that government is facing economic collapse. Your net worth is not your own; it is community property, and your government can, if anything, become more vicious than a divorce lawyer. First Worlders are not yet queued up, as are the Argentines in the photo above, because the First World has not reached that stage in the progression as yet. What these Argentines are doing is a last, desperate measure. However, First Worlders may use the Argentine situation to forewarn themselves. They may choose to diversify their wealth beyond the confines of the nation-state to which they are presently married – and to do so whilst they still retain a modicum of control over their own wealth. Jeff Thomas is British and resides in the Caribbean. The son of an economist and historian, he learned early to be distrustful of governments as a general principle. Although he spent his career creating and developing businesses, for eight years he penned a weekly newspaper column on the theme of limiting government. He began his study of economics around 1990, learning initially from Sir John Templeton, then Harry Schulz and Doug Casey, and later others of an Austrian persuasion.last_img read more

Scratch another Guinea worm hot spot off the list

first_imgScratch another Guinea worm hot spot off the list.One of the countries hardest hit with the parasite — South Sudan — has finally stopped transmission, the Carter Center announced Wednesday.The country reported zero cases in 2017 and hasn’t had a case in 15 months. There are also no signs Guinea worm is circulating in dogs in South Sudan, as it is in Chad and Mali.”I come from an area that had the most Guinea worm,” South Sudan’s Minister of Health, Dr. Riek Gai Kok, said at a news conference. “I never thought — even one time — that the area would be free of Guinea worm, let alone all of South Sudan would be.””But today that dream has come true,” he added.The international effort to eradicate Guinea worm has been a huge success. Back in the mid-’80s, more than 3 million people were catching the parasite each year. Now Guinea worm is circulating in only three countries: Ethiopia, Mali and Chad. Last year, there were only 30 human cases worldwide.But to eradicate the worm, health workers also have to stop transmission in animals. Last year, there were nearly a thousand cases in dogs and cats in Chad and Mali.Guinea worm is a horrific infection. First, a painful blister starts to form on the skin. Then a thin, white worm — up to 3 feet long — emerges from the blister over the course of a few weeks. It is an incredibly painful process and temporarily handicaps a person while he or she waits for the worm to come out of the skin.People catch Guinea worm by drinking contaminated water. Simply filtering drinking water can stop transmission of the parasite. An infected person can also stop the spread of the parasite by keeping the emerging worm away from water. When the worm touches water, it releases tens of thousands of baby worms and contaminates the whole body of water.Back in 2006, South Sudan reported more than 20,000 cases, making it the third hardest hit country in the world. Only Nigeria and Uganda had reported higher annual cases, at about 650,000 and 126,000, respectively.”This an incredible story, given all of the challenges that South Sudan has faced, especially the ongoing conflict,” says Dr. Sharon Roy of the Centers for Disease Control and Prevention, who leads an international team working on Guinea worm eradication.Former President Jimmy Carter has led a massive campaign to eradicate the worm. “I’d like for the last Guinea worm to die before I do,” he told reporters.Sudan was especially challenging. Civil war has plagued the region since the 1960s. To begin the eradication program in the area, Carter had to negotiate a special “Guinea worm cease-fire” back in 1995. And just a few years ago, the Carter Center had to evacuate its staff from the country because of violence.”If South Sudan can stop Guinea worm, Chad can do it. Mali can do it. Ethiopia can do it, too,” Roy says. “It’s really an amazing accomplishment.” Copyright 2018 NPR. To see more, visit http://www.npr.org/.last_img read more

Taxi Companies line up to overhaul Japans staid cab sector

© 2018 AFP This week, Uber’s CEO Dara Khosrowshahi made his first visit to Japan since taking over at the firm, touting “promising partnership talks” on his Twitter feed, where he posted smiling photos of himself alongside Prime Minister Shinzo Abe and Toyota chief Akio Toyoda.The global ride-hailing giant has had little success so far penetrating Japan’s taxi market, which is governed by strict regulations.But instead of pursuing the aggressive strategies it has used elsewhere, the company is opting for a charm offensive, emphasising cooperation rather than confrontation.”Clearly we need a different way of doing business in Japan,” Khosrowshahi said at an event in Tokyo covered by local media.”We need to come in with partnership in mind, and in particular a partnership with the taxi industry here, which actually has a very, very strong product,” he added.”But that product hasn’t kept up with technological change”.Rushing to catch upJapan’s taxi companies have seen little reason until now to innovate, shunning the upheaval seen across the industry elsewhere in the world.Hailing a taxi rarely takes more than a few seconds in major Japanese cities, with the vast majority hired from cab ranks. Uber has had little success so far penetrating the Japanese market But with major sporting events—the Rugby World Cup next year and the 2020 Olympics—expected to bring in an unprecedented number of tourists, companies including Uber think the time is right for a taxi revolution.”We know that the first thing many people do when they arrive in a country is open the Uber app. Our vision is for visitors to Japan to get a taxi via the app, with no language issues,” Uber spokesman Chris Brummitt told AFP.For now, the company has a limited presence in Japan with its premium service UberBLACK, but finding a local partner could change that.”We believe there is immense potential to reach more customers by partnering,” Brummitt said.Uber is far from alone in targeting the market, with Chinese ride-hailing giant Didi Chuxing and Japanese telecom firm SoftBank announcing a deal in early February to develop a taxi app in Japan.

Companies line up to overhaul Japan’s staid cab sector (2018, February 26) retrieved 18 July 2019 from https://phys.org/news/2018-02-taxi-companies-line-overhaul-japan.html Japan’s taxi market is governed by strict regulations Hailing a taxi rarely takes more than a few seconds in major Japanese cities “We’re trying to make it easier for everybody to hail a taxi with more reasonable fares,” said Ryota Fujimura, a spokesman for JapanTaxi, the subsidiary in charge of the project.JapanTaxi estimates the app could reduce ride costs by between 15 to 40 percent for customers, and the company has attracted 7.5 billion yen ($70 million) from Toyota for other projects to update the sector.Under pressure from competitors and anticipating a drop in private car purchases, Toyota says the investment is “part of our transformation from a strict car maker to a provider of mobility.”The Toyota tie-up hopes to bring Japan’s taxis into the digital age, equipping them with on-board tablets and AI technology to help better predict customer demand.Electronics giant Sony is jumping in too, announcing plans to partner with six Japanese companies who would receive AI technology for their vehicles, some 10,000 in Tokyo alone.The innovations aim to rejuvenate the client base for taxis, but perhaps also their drivers, who at present have an average age of 60.And at carmaker Nissan, developers are taking things one step further, testing “robo-taxis”, driverless cabs that could be particularly tempting for Japan given its labour shortages.For now, the cars will be moving around a test route, with a safety driver in place but not touching the steering wheel.But Nissan’s partner Renault hopes it can bring the taxis to market by 2020—just in time for the Olympics. Sony jumps into Japan taxi market with AI app plans With their white-gloved, greying drivers and lace-covered seating, Japan’s taxis seem to belong to another era, but as the 2020 Olympics approach, the sedate sector is facing a quiet revolution.

Scientists help robots understand humans with board game idea

Sadler said it is a signifcant challenge to find ways for a machine to query a human that efficiently takes advantage of the human’s expertise.”Humans are particularly good at accurately answering yes/no questions,” he said. He explained that it is important to minimize the number of queries, while maximizing the value of each one, so as not to waste the human’s time or endanger a soldier who has duties to perform in a dangerous environment.The 20 questions game is a classic pastime, where players can only ask questions whose response is yes or no, while attempting to identify an object. The sequence of questions is designed so that the player can rapidly figure out the answer: “Is it bigger than a breadbox,” “is it alive,” and so on; however, in the Army problem, it is possible that the question may be answered in error.”Unlike the actual 20 Questions game, we admit the possibility that a question might be answered in error,” he said. “We call this the noisy 20 questions game.”ARL and University of Michigan researchers developed a method to automatically formulate a sequence of questions to narrow down the error and provide an answer to the question, “what is the value of x”. The researchers have shown that their querying will achieve the minimum mean-square error between their best guess and the unknown true value of x.Moving forward, as part of research into artificial intelligence and human-machine teaming, ARL will apply methods such as the 20 Questions paradigm to Soldier-robot teaming.

In the game, a player wishes to estimate an unknown value on a sliding scale by asking a series of questions whose answer is binary (yes or no). In this way, scientists say, their research findings could lead to new techniques for machines to ask other machines questions, or for machines and humans to query each other.ARL senior scientist Dr. Brian Sadler teamed with University of Michigan researchers Hye Won Chung, Lizhong Zheng, and Professor Alfred O.

A real, purposeful conversation, especially in complicated military environments, is different. It requires the AI system to understand a whole sequence of questions and answers, and to handle every question or answer with consideration of what has been asked or answered before. Such computer algorithms do not yet exist, and the scientific theory for building such algorithms is not yet developed.” read more

Google case set to examine if EU data rules extend globally

first_imgIn this April 17, 2007, file photo exhibitors of the Google company work in front of a illuminated sign at the industrial fair Hannover Messe in Hannover, Germany. Google is taking its legal fight against an order requiring it to extend “right to be forgotten” rules to its search engines globally to Europe’s top court. (AP Photo/Jens Meyer, File) Google is going to Europe’s top court in its legal fight against an order requiring it to extend “right to be forgotten” rules to its search engines globally. Google invokes free speech in French fine appeal The technology giant is set for a showdown at the European Union Court of Justice in Luxembourg on Tuesday with France’s data privacy regulator over an order to remove search results worldwide upon request.The dispute pits data privacy concerns against the public’s right to know, while also raising thorny questions about how to enforce differing legal jurisdictions when it comes to the borderless internet.The two sides will be seeking clarification on a 2015 decision by the French regulator requiring Google to remove results for all its search engines on request, and not just on European country sites like google.fr.Google declined to comment ahead of the hearing. Its general counsel, Kent Walker, said in a blog post in November that complying with the order “would encourage other countries, including less democratic regimes, to try to impose their values on citizens in the rest of the world.””These cases represent a serious assault on the public’s right to access lawful information,” he added.In an unusual move, the court has allowed a collection of press freedom, free speech and civil rights groups to submit their opinions on the case. These groups agree with Google that forcing internet companies to remove website links threatens access to information and could pave the way for censorship by more authoritarian regimes such as China, Russia and Saudi Arabia.The court’s ruling is expected within months. It will be preceded by an opinion from the court’s advocate general.The case stems from a landmark 2014 Court of Justice ruling that people have the right to control what appears when their name is searched online. That decision forced Google to delete links to outdated or embarrassing personal information that popped up in searches of their names.Authorities are now starting to worry about the risk that internet users can easily turn to proxy servers and virtual private networks to spoof their location, allowing them to dig up the blocked search results.Google said in its most recent transparency report that it has received requests to delete about 2.74 million web links since the ruling, and has deleted about 44 percent of them.Not all requests are waved through. In a related case that will also be heard Tuesday, the EU court will be asked to weigh in on a request by four people in France who want their search results to be purged of any information about their political beliefs and criminal records, without taking into account public interest. Google had rejected their request, which was ultimately referred to the ECJ. Explore furthercenter_img This document is subject to copyright.

Portable tricorder scans life signs

first_img A Star Trek-inspired handheld device for sophisticated medical diagnostics The device, which combines a handheld sensor and an app running on an Android smartphone or tablet, was partly inspired by the “tricorder” portable scanning/data-capture machine, used by crewmembers of starships in the fictional “Star Trek” universe.The sensor works by using a silicon chip smaller than a fingertip, which is divided into four “zones” to count the number of four different types of metabolites (small molecules found in body fluids). It can detect multiple types of these materials simultaneously, speeding up the process of data-acquisition. The relative levels of these metabolites can provide an indication of the general health of the patient, as well as the progress of certain diseases.The scanner transmits its findings to the Android device, which can provide rapid diagnosis in the case of medical conditions including prostate cancer and heart disease. The chip is made from a new form of complementary metal oxide semiconductor (CMOS) which is often found in imaging devices, is cheap to manufacture, and is more compact than its predecessors.The development team believes this system offers a low-cost means of tracking disease in its early stages, and to provide rapid data results and diagnosis in locations where this may previously have been difficult or impossible to achieve.

Boeing FAA say more time needed for fix of troubled 737 Max

first_imgIn this March 14, 2019, file photo, a worker walks next to a Boeing 737 MAX 8 airplane parked at Boeing Field in Seattle. U.S. aviation regulators said Monday, April 1, Boeing needs more time to finish changes in a flight-control system suspected of playing a role in two deadly crashes. (AP Photo/Ted S. Warren, File) Explore further Boeing and U.S. aviation regulators say the company needs more time to finish changes in a flight-control system suspected of playing a role in two deadly crashes. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The Federal Aviation Administration said Monday it anticipates Boeing’s final software improvements for 737 Max airliners “in the coming weeks.”Boeing was expected to complete the work last week, but FAA spokesman Greg Martin said the company needs more time to make sure it has identified and addressed all issues.Chicago-based Boeing offered the same timetable as it works to convince regulators that it can fix software on the planes.”Safety is our first priority, and we will take a thorough and methodical approach to the development and testing of the update to ensure we take the time to get it right,” said Boeing spokesman Charles Bickers.Boeing needs approval not just from FAA, but elsewhere, including Europe and China, where safety officials have indicated they will conduct their own reviews.The planes have been grounded around the world since mid-March.The news from the FAA suggests that airlines could be forced to park their Max jets longer than they expected. Airlines that own Max jets are scrambling other planes to fill some Max flights while canceling others.”We are aware that the resumption of service for our 737 Max aircraft may be further delayed, and our team will work with all customers impacted by any flight cancellations,” said American Airlines spokesman Ross Feinstein.American Airlines had been pointing toward a late-April return of its 24 Max 8s. Over the weekend, Southwest Airlines announced that its 34 Max 8s will be removed from the schedule through May instead of mid-April. United Airlines has idled its 14 Max 9s through June 5.Separately, U.S. regulators and Boeing are awaiting a preliminary report from Ethiopian investigators into the March 10 crash of an Ethiopian Airlines Max 8 jet shortly after takeoff from Addis Ababa. The report will be scrutinized for information from the plane’s data recorders that might suggest similarities between the doomed flight and the Oct. 29 crash of a Lion Air Max 8 into the Java Sea off Indonesia. The two crashes killed 346 people.Data from the Indonesian plane indicates that pilots unsuccessfully fought the automated anti-stall system for control of the plane, which plunged into the sea shortly after takeoff. According to published reports, the same system activated on the Ethiopian Airlines flight.Boeing is making changes in an automated system that is designed to prevent the plane’s nose from rising, which can lead to a dangerous aerodynamic stall. The changes include relying on readings from more than one sensor before the anti-stall system activates and pushes the nose down, and making the system’s actions less severe and easier for pilots to handle. Boeing has said it will pay to train pilots on the technology.Two American Airlines pilots who attended a session with Boeing experts last week expressed satisfaction with the manufacturer’s changes. American’s chief 737 pilot, Roddy Guthrie, said Boeing added “some checks and balances in the system that will make the system much better.”Congress, meanwhile, is looking into the relationship between Boeing and the FAA. The House Transportation and Infrastructure Committee said Monday that it had requested records from both Boeing and the FAA related to the certification of the 737 Max.center_img © 2019 The Associated Press.

Legendary Persecuted CodeBreaker Alan Turing Finally Recognized for His Achievements

first_img Beyond Tesla: History’s Most Overlooked Scientists The Top 10 Revolutionary Computers If it weren’t for the legendary World War II code-breaker Alan Turing, the outcome for the Allied forces might have looked very different. The mathematician and computer scientist has been widely credited with hastening the end of the war, thanks to his work decoding German naval messages. But only seven years after the end the war, Turing, who was gay, was convicted of “gross indecency” for his relationship with a 19-year-old man. Turing wasn’t formally pardoned until 2014. Now, 65 years after Turing’s death, the Bank of England is recognizing the trailblazer’s contributions to science and technology by featuring his face on the brand-new design of their 50-pound note. “It was nothing short of a tragedy how a country he had served with such distinction treated him after the war, persecuting him for his homosexuality,” said Demis Hassabis, a British artificial intelligence (AI) researcher, at the unveiling ceremony in Manchester. “That’s why it’s wonderful to see Turing on the note, as a powerful symbol of the long overdue recognition he deserves.” Not only did Turing’s contributions to math and computer science aid the Allied war effort, they also laid the foundations for modern computers. In his 1936 paper titled “On Computable Numbers,” Turing invented the concept of algorithms, sets of instructions that dictate how computers operate, BBC reported. He was also one of the earliest computer scientists to begin thinking about AI. His ‘Turing test’ is still used to determine whether a machine is “intelligent” or not. “As the father of computer science and artificial intelligence, as well as a war hero, Alan Turing’s contributions were far ranging and path breaking,” Mark Carney, governor of the Bank of England, said in a statement. “Turing is a giant on whose shoulders so many now stand.” The new banknote won’t just feature Turing’s face. It will also include a ticker tape of binary code that spells out his birthday (June 23, 1912), a depiction of the machine he used to help break the German Enigma code, and his signature. Turing wasn’t the only scientist considered for this new note. In total, 989 scientists were nominated. The short list included Rosalind Franklin, Stephen Hawking and Adam Lovelace, among others.

Cats in Australia Kill Over 2 Billion Wild Animals Each Year

first_img Australian officials are exploring multiple strategies for controlling populations of feral cats, including shooting, trapping and poisoning them with bait such as toxic sausages. Such culls are expected to eradicate around 2 million cats by 2020, but some species of vulnerable Australian wildlife may be running out of time, said study co-author Christopher Dickman, a professor in terrestrial ecology with the School of Life and Environmental Sciences at the University of Sydney. Cats are recognized as a threat to 35 species of birds, 36 mammal species, seven reptile species and three amphibian species, according to Australia’s Department of Sustainability, Environment, Water, Population and Communities (SEWPAC). “Many of Australia’s native species cannot withstand these high levels of predation and will become increasingly at risk of extinction unless the problem of cats in Australia is solved,” Dickman said in the statement. Here, Kitty, Kitty: 10 Facts for Cat Lovers When cats roam free, small wild animals die. And the body count in Australia exceeds 2 billion native animals per year. Environmental researchers in Australia compiled the alarming figure by combing through hundreds of studies on the predatory habits of Australia’s free-ranging pet cats as well as feral felines. The scientists documented cats’ historic and ongoing toll on Australian wildlife in the book “Cats in Australia” (CSIRO Publishing, 2019). In just one day, Australia’s millions of cats kill approximately 1.3 million birds, 1.8 million reptiles and over 3.1 million mammals.

Current estimates of the number of feral cats in Australia range from about 2 million to more than 6 million during years with a lot of rainfall, when prey is abundant. And every feral cat kills about 740 native animals annually, co-author Sarah Legge, a principal research fellow with the School of Earth and Environmental Sciences at Australia’s University of Queensland, said in a statement. There are also about 4 million pet cats in Australia. Pet owners who allow their cats to spend time outdoors may never witness their beloved animal’s killer instincts. Yet a single pet cat kills, on average, about 75 animals each year. That may not sound like much compared to the death toll racked up by feral cats. However, urban cat populations tend to be denser than in rural areas; with about 180 cats per square mile (60 per square kilometer) wildlife in urban areas pay a deadly price, Legge explained. “As a result, cats in urban areas kill many more animals per square kilometer each year than cats in the bush,” she said.

NASA Set To Launch a DeepSpace Atomic Clock Tonight

first_img Follow Kasandra @KassieBrabaw. Follow us on Twitter @Spacedotcom and on Facebook. Fusion Powered Spacecraft Could Be Just A Decade Away NASA is set to launch an incredible new atomic clock into orbit on a Falcon Heavy today (June 24) in a technology demonstration mission that could transform the way humans explore space. The Deep Space Atomic Clock, developed by NASA’s Jet Propulsion Laboratory, is a space-ready upgrade to the atomic clocks we use here on Earth and to the clocks that already fly on satellites like those that provide GPS. Ideally, this new atomic clock will make spacecraft navigation to distant objects in space — on the journey to Mars, for example — more autonomous, NASA said in a statement. The precision in measurement of the spacecraft’s position that scientists hope to get with the Deep Space Atomic Clock will allow spacecraft traveling in deep space to act on their own, without much communication with Earth. It’d be a huge improvement to how spacecraft are currently navigated, NASA said.

Astronomers already use clocks to navigate in space. They send a signal to the spacecraft, which sends it back to Earth. The time of that round trip tells scientists the spacecraft’s distance from Earth. That’s because the signal is traveling at the speed of light, so armed with the time it took to go to the spacecraft and back, finding distance is but a simple calculation away. By sending multiple signals over time, scientists can calculate a spacecraft’s trajectory — both where it was and where it’s going. But in order to know a spacecraft’s location within a small margin of error, astronomers need very precise clocks that can measure billionths of a second, according to NASA. They also need clocks that are extremely stable. “Stability” here refers to how consistently a clock measures a unit of time. While you’d think that clocks always measure the same length of time as a “second,” clocks have a tendency to drift and slowly mark longer and longer times as a “second.” For measuring the locations of spacecrafts in distant space, astronomers need their atomic clocks to be consistent to better than a billionth of a second over days and weeks. Modern clocks, from those we wear on our wrists to those used on satellites, most often keep time using a quartz crystal oscillator. These take advantage of the fact that quartz crystals vibrate at a precise frequency when voltage is applied to them, NASA said in the statement. The vibrations act like the pendulum in a grandfather clock. But, by the standards of space navigation, quartz crystal clocks aren’t very stable at all. After six weeks, they may be off by a full millisecond, which translates at the speed of light to 185 miles (300 kilometers). That much error would have a huge impact on measuring the position of a fast-moving spacecraft, NASA said. Atomic clocks combine quartz crystal oscillators with certain types of atoms to create better stability. NASA’s Deep Space Atomic Clock will use mercury atoms and be off by less than a nanosecond after four days and less than a microsecond after 10 years. It would take 10 million years for the clock to be wrong by a whole second, according to NASA. Related: A NASA Atomic Clock on SpaceX’s Next Falcon Heavy Will Pioneer Deep-Space Travel Tech It may not be surprising to learn that atomic clocks take advantage of the structure of atoms, which are composed of a nucleus of protons and neutrons surrounded by electrons. The atoms of each element have a distinct structure, with a different number of protons in the nucleus. While the number of electrons each type of atom has can vary, the electrons occupy distinct energy levels, and a jolt of exactly the right amount of energy can cause an electron to jump to a higher energy level around the nucleus. The energy required to make an electron do this jump is unique to each element and consistent to all atoms of that element. “The fact that the energy difference between these orbits is such a precise and stable value is really the key ingredient for atomic clocks,” Eric Burt, an atomic clock physicist at JPL, said in the statement. “It’s the reason atomic clocks can reach a performance level beyond mechanical clocks.” Humans To Mars? Here’s What We’ll NeedDava Newman, NASA Deputy Administrator, explains how solar-electric propulsion, deep space atomic clocks, spacesuits, and laser communication are key technologies for humans to explore Mars and beyond.Credit: NASAVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Better Bug Sprays?01:33关闭选项Automated Captions – en-US facebook twitter 发邮件 reddit 链接https://www.livescience.com/65777-nasa-launching-deep-space-atomic-clock.html?jwsource=cl已复制直播00:0002:3202:32Your Recommended Playlist01:33Better Bug Sprays?04:24Sperm Whale Befriends Underwater Robot01:08Why Do French Fries Taste So Bad When They’re Cold?00:29Robot Jumps Like a Grasshopper, Rolls Like a Ball02:27Robotic Arms01:09Robots to the Rescue关闭  NASA Wants Robots to Sniff Out Moon Pits for Astronaut Homes In essence, atomic clocks can correct themselves. In an atomic clock, the frequency of the quartz oscillator is transformed into the frequency that is applied to a collection of atoms from a specific element. If the frequency is correct, it will cause many electrons in the atoms to jump energy levels. But if it’s not, fewer electrons will jump. That tells the clock that the quartz oscillator is off-frequency and how much to correct it. On the Deep Space Atomic Clock, this correction is calculated and applied to the quartz oscillator every few seconds. But that’s not all that makes the Deep Space Atomic Clock special. This clock doesn’t just use mercury atoms, it also uses charged mercury ions. Because ions are atoms that have electric charge, they can be contained in an electromagnetic “trap.” This keeps the atoms from interacting with the walls of a vacuum chamber, a common problem with the neutral atoms used in regular atomic clocks. When they interact with the vacuum walls, environmental changes such as temperature can cause changes in the atoms themselves, and lead to frequency errors. The Deep Space Atomic Clock won’t be subject to such environmental changes, according to NASA, and so will be 50 times more stable than the clocks used on GPS satellites. After the clock launches today, scientists will be able to begin testing the clock’s precision as it spends days, then months in orbit. The Deep Space Atomic Clock will launch from Kennedy Space Center in Florida on a SpaceX Falcon Heavy rocket as one of two dozen payloads. The 4-hour launch window opens at 11:30 p.m. EDT (0330 June 25 GMT); visit Space.com tomorrow for complete coverage of the launch.last_img read more

Asthana bribery case Delhi HC directs CBI to maintain status quo till

first_imgSupreme Court order on CBI row extremely positive development: Jaitley SHARE SHARE EMAIL judiciary (system of justice) RELATED COMMENT October 29, 2018 SHARE The Delhi High Court Monday ordered the CBI to maintain status quo till November 1 on proceedings against its Special Director Rakesh Asthana, who was sent on leave by the government. A bench of Justice Najmi Waziri questioned the Central Bureau of Investigation (CBI) for not filing reply to pleas of Asthana and another official Devender Kumar, Deputy Superintendent of Police, seeking quashing of FIR lodged against them. CBI has lodged FIR against Asthana and Kumar in connection with bribery allegations. The high court also directed the CBI to file reply on the two pleas on or before November 1. The CBI prosecutor told the High Court that delay in filing of reply occurred as the case files have been sent to Central Vigilance Commission (CVC) and sought more time for filing the response. Kumar, earlier the investigating officer in a case involving meat exporter Moin Qureshi, was arrested on October 22 on the allegations of forgery in recording the statement of businessman Sathish Sana, who had alleged to have paid bribe to get relief in the case. The High Court had on October 23 directed the CBI to maintain status quo on the criminal proceedings initiated against its special director Asthana, who has challenged the FIR lodged against him on bribery allegations.center_img corruption & bribery A file photo of CBI Additional Director Rakesh Asthana   –  V Sudershan Published on SC sets 2-week deadline for probe on CBI chief Below the line: Twists and turns at CBI COMMENTSlast_img read more
