first_imgJust give up. AI’s got you beat. Getty Images An artificial intelligence algorithm is putting humans to shame by solving a Rubik’s Cube in just over a second. The algorithm, called DeepCubeA, was created by researchers at University of California, Irvine. The results are described in a study published Monday in Nature Machine Intelligence. The algorithm was presented with 10 billion combinations for the cube. The goal was to decode them all in 30 moves, which exceeds or is equal to human performance. DeepCubeA was then tested on 1,000 combinations and solved them all, doing so in the least number of moves around 60% of the time.Pierre Baldi, an author of the study and professor of computer science at UCI, told The BBC the algorithm “learned on its own.” He added that he believed the “AI’s form of reasoning is completely different from a human’s.”The authors also discussed their research in a paper published last June, which described a machine that could solve a Rubik’s Cube without algorithms created by human beings.They’re not the only ones who’ve looked for shortcuts to solving the complex puzzle. Last year, an MIT robotics student and a software developer built a robot that can solve a Rubik’s Cube in 0.38 seconds. And for anyone looking for an easy way out, there’s a self-solving Rubik’s Cube that’ll spare you plenty of time and stress.  Lenovo 130-15AST 15.6-inch laptop: $210 (save $90) $59 at eBay Free Echo Dot with an Insignia or Toshiba TV (save $50) Other Labor Day sales you should check out Best Buy: In addition to some pretty solid MacBook deals that have been running for about a week already, Best Buy is offering up to 40% off major appliances like washers, dryers and stoves.

Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening. Perhaps unsurprisingly, Labor Day doesn’t bring out bargains to compete with the likes of Black Friday (which will be here before you know it), but there are definitely some sales worth your time.For example:We’ve rounded up the best Labor Day mattress deals.We’ve also gathered the best Labor Day laptop deals at Best Buy.The 2019 Vizio P Series Quantum is back under $999.Be sure to check out Amazon’s roughly three dozen Labor Day deals on TVs and audio. Google Express is having a big sale as well, one that includes deals on game consoles, AirPods, iPhones, laptops and more.Below I’ve rounded up a handful of individual items I consider to be the cream of the crop, followed by a handy reference guide to other Labor Day sales.

first_img Journal information: Physical Review Letters More information: Experimental and Theoretical Evidence for Pressure-Induced Metallization in FeO with Rocksalt-Type Structure, Phys. Rev. Lett. 108, 026403 (2012) DOI:10.1103/PhysRevLett.108.026403AbstractElectrical conductivity of FeO was measured up to 141 GPa and 2480 K in a laser-heated diamond-anvil cell. The results show that rock-salt (B1) type structured FeO metallizes at around 70 GPa and 1900 K without any structural phase transition. We computed fully self-consistently the electronic structure and the electrical conductivity of B1 FeO as a function of pressure and temperature, and found that although insulating as expected at ambient condition, B1 FeO metallizes at high temperatures, consistent with experiments. The observed metallization is related to spin crossover.via Physics Synopsis Explore further (PhysOrg.com) — Scientists studying the rotation of the Earth have long known that our planet doesn’t have a perfect spin. Most believe this is due to the different types of materials that make up the core, mantle and crust, which all have different rates of spin causing inherent friction. Most models researchers have developed however agree that in order for the planet to wobble the way it does, the mantle would have to respond to the magnetic tug of the core. The problem with this though, is that the mantle is made mostly of rock, not metal, which means it’s not supposed to be conductive. A new kind of metal in the deep Earth Citation: Part of Earth’s mantle shown to be conductive under high pressure and temperatures (2012, January 20) retrieved 18 August 2019 from https://phys.org/news/2012-01-earth-mantle-shown-high-pressure.html © 2011 PhysOrg.com New research by a Kenji Ohta and his colleagues at Osaka University in Japan indicates they’ve found a possible explanation. As they describe in their paper published in Physical Review Letters, it appears that Wustite (FeO), believed to be one of the components that make up the Earth’s mantle, can be made to conduct electricity at high pressure and high temperatures.This new work by the team builds on findings from the 1980’s that showed that FeO becomes more conductive when exposed to shock waves. To find out if other conditions might cause the same outcome, the team placed a sample of FeO in a diamond anvil and heated it using a laser. As the experiment proceeded, they also measured the conductivity of the FeO sample.After heating the sample to 1600°C and applying 70 gigapascals of pressure, the team found the sample became as conductive as an average metal. They also noted it did so without any changes occurring to its structure.To find out if the same conductive properties would occur under more harsh conditions, comparable to those found inside the Earth, the team turned up the temperature to 2200°C while ratcheting up the pressure to 1.4 million atmospheres and found the same results. Such measurements suggest, the team theorizes, that the same conductive properties would likely hold under even more extreme conditions such as those found near the boundary between the mantle and the core.To better understand why FeO becomes conductive under high pressure and heat, the team did density and electrical conductivity tests as they relate to temperature and pressure and now believe that the metallization is related to spin crossover.

first_img by NPR News Avie Schneider 8.23.19 1:28pm Updated at 11:35 a.m. ETSignaling the possibility of more interest-rate cuts, Federal Reserve Chairman Jerome Powell said the central bank will “act as appropriate” to sustain the economic expansion as the trade war with China takes a toll on global growth and the U.S. economy. In prepared remarks Friday to a Kansas City Fed gathering in Jackson Hole, Wyo., Powell said the economy faces “significant risks” and cited several developments that have roiled financial markets in recent weeks. Those developments include new U.S. tariffs on imports from China; signs of a global slowdown, namely in the economic powerhouses Germany and China; and the growing possibility that the United Kingdom will leave the European Union without a deal.”Trade policy uncertainty seems to be playing a role in the global slowdown and in weak manufacturing and capital spending in the United States,” Powell said. He said the U.S. economy has continued to perform well, driven by consumer spending, but job creation has slowed. “Based on our assessment of the implications of these developments, we will act as appropriate to sustain the expansion,” Powell said.Last month, the Fed cut interest rates for the first time in over a decade, lowering the cost of borrowing for credit cards, auto loans and mortgages. President Trump has repeatedly pressured the Fed to lower interest rates further to boost the economy, and this week, he called for a dramatic one-percentage-point cut. On Friday, Trump again tweeted his criticism of the central bank. “We have a very strong dollar and a very weak Fed. … My only question is, who is our bigger enemy, Jay Powell or Chairman Xi?” Trump’s tweets came shortly after China announced retaliatory tariffs against $75 billion in U.S. goods.In his remarks, Powell said that “while monetary policy is a powerful tool that works to support consumer spending, business investment, and public confidence, it cannot provide a settled rulebook for international trade.”He also addressed another issue on the mind of market watchers: whether the long U.S. expansion is leading banks and other financial firms to take more risks. “We have not seen unsustainable borrowing, financial booms, or other excesses of the sort that occurred at times [before the Great Recession], and I continue to judge overall financial stability risks to be moderate,” he said. “But we remain vigilant.”Copyright 2019 NPR.
