The road will be completely closed during these times, with no alternate or detour routes available. Plan your trip accordingly. Expected to occur on Monday, April 15, Tuesday, April 16, and Wednesday, April 17, the Seward Highway will be closed nightly between MP 84 and 86 between 9:00pm and 3:00am.
Now playing: Watch this: 5:30 Internet Services Music MySpace may have lost 12 years of music in a “server migration project.” Lionel Bonaventure / AFP/Getty Images MySpace may have lost your digital memories in a server migration.”As a result of a server migration project, any photos, videos, and audio files you uploaded more than three years ago may no longer be available on or from Myspace,” it said in a note at the top of the site.”We apologize for the inconvenience. If you would like more information, please contact our Data Protection Officer at DPO@myspace.com.” Tags 5 Comments Share your voice Andy Baio, one of the people behind Kickstarter, tweeted that it could mean millions of songs uploaded between the site’s Aug. 1, 2003 launch and 2015 are gone for good.”Myspace accidentally lost all the music uploaded from its first 12 years in a server migration, losing over 50 million songs from 14 million artists,” he wrote Sunday.”I’m deeply skeptical this was an accident. Flagrant incompetence may be bad PR, but it still sounds better than ‘we can’t be bothered with the effort and cost of migrating and hosting 50 million old MP3s,’ ” Baio noted.MySpace didn’t immediately respond to a request for further comment.It might seem like a dim and distant memory now, but MySpace was an essential springboard for musicians like Arctic Monkeys in 2005 and the most popular site in the US in 2006. It was got a makeover back in 2013, when it was refurbished and rebranded as a cool place to share music and video.First published at 5:07 a.m. PT.Updated at 9:44 a.m. PT: Adds background detail.

The researchers, Can Onur Avci et al., at MIT and ETH Zürich, have published a paper on the new memory concept in a recent issue of Applied Physics Letters.”With some device and structural optimization, the bit density of existing random access memory devices may be increased by several factors, with the possibility of all-electrical operation,” Avci told Phys.org.Magnetoresistance effects date back to around 1850, when Lord Kelvin demonstrated that applying a magnetic field to a metal object increases the object’s electric resistance in one direction and decreases it in the perpendicular direction. Since then, several other types of magnetoresistance have been discovered. Most notably, Albert Fert and Peter Grünberg won the 2007 Nobel Prize in Physics for their discovery of giant magnetoresistance, which is used to make magnetic field sensors that are found in many of the hard disk drives in today’s computers.In 2015, scientists discovered the newest magnetoresistance effect, called unidirectional spin Hall magnetoresistance. This effect differs from other kinds of magnetoresistance in that the change in resistance depends on the direction of either the magnetization or the electric current. As the scientists explain, this direction-dependent effect occurs because the spin-polarized electrons created by the spin Hall effect in a nonmagnetic layer are deflected in opposite directions by the magnetization of the adjacent magnetic layer. Previously, this new effect was demonstrated in two-layer structures consisting of a nonmagnetic and a magnetic layer. But by adding another magnetic layer, the researchers achieved a great potential advantage for memories: the ability to distinguish between not just two, but four magnetic states. Other types of magnetoresistance effects are only sensitive to the relative orientation of the magnetizations (parallel or antiparallel), although it’s possible to have four distinct magnetic states. Because the new effect is sensitive to the magnetization direction of individual layers, it can distinguish between all four states.The researchers then demonstrated four distinct resistance levels corresponding to the four different magnetic states in their three-layer device. They showed that the four resistance levels can be read out by a simple electric measurement, paving the way for the development of an all-electrical multi-bit-per-cell memory device.The researchers expect that it will be possible to scale up this memory device to higher bit densities by adding more layers, which could realistically enable eight different magnetization states, each with its own unique resistance level. In the future, the researchers also plan to look for materials that exhibit a larger unidirectional spin Hall magnetoresistance effect, which would further enhance the performance of these memory devices. (Left) With a single ferromagnetic layer, the system has two resistance levels. (Right) Adding another ferromagnet to the system creates four levels of resistance, corresponding to the four different magnetic states indicated by the arrows.

Now in a new paper, the same researchers have demonstrated that the effect can be used to design memories with four distinct stable magnetic states, allowing the memories to store four bits of information in a single magnetic structure. More information: Can Onur Avci et al. “A multi-state memory device based on the unidirectional spin Hall magnetoresistance.” Applied Physics Letters. DOI: 10.1063/1.4983784ABSTRACTWe report on a memory device concept based on the recently discovered unidirectional spin Hall magnetoresistance (USMR), which can store multiple bits of information in a single ferromagnetic heterostructure. We show that the USMR with possible contribution of Joule heating-driven magnetothermal effects in ferromagnet/normal metal/ferromagnet (FM/NM/FM) trilayers gives rise to four different 2nd harmonic resistance levels corresponding to four magnetization states (⇉⇉, ⇄⇄, ⇆⇆, ⇇⇇) in which the system can be found. Combined with the possibility of controlling the individual FMs by spin-orbit torques, we propose that it is possible to build an all-electrical lateral two-terminal multi-bit-per-cell memory device. © 2017 Phys.org Smart multi-layered magnetic material acts as an electric switch Journal information: Applied Physics Letters Citation: New magnetoresistance effect leads to four-state memory device (2017, June 5) retrieved 18 August 2019 from https://phys.org/news/2017-06-magnetoresistance-effect-four-state-memory-device.html Explore further This document is subject to copyright.

In an expression of faith in the assertion of Union Minister Pon Radhakrihnan that permission will be secured to hold bull taming sport ‘Jallikattu’ in Tamil Nadu, DMK on Friday postponed its proposed hunger strike over the issue.“I feel that the proposed hunger strike (to seek nod for Jallikattu) at Alanganallur (Madurai) on December 28 to be led by party treasurer M K Stalin can be postponed considering the letter of Union Minister Pon Radhakrishnan (that permission would be obtained to hold the event),” Karunanidhi said in a release here. Also Read – Rain batters Kolkata, cripples normal lifeRadhakrishnan had said on Thursday, replying to Karunanidhi’s letter to him over the issue, “I am confident that we will be getting permission to hold Jallikattu on Pongal day based on the talks held for the past one month… Our efforts have the support of Prime Minister Narendra Modi.” Citing the assurance, the DMK chief also appealed to pro-Jallikattu groups who had sought his party’s support, “to accept the postponement of the protest by accepting the confidence expressed by Union Minister Pon Radhakrishnan.” An annual affair in southern parts of rural Tamil Nadu, it has socio-economic and cultural dimensions to it.
