Pelicans3850.5100.4 That’s more proportionate to the small difference separating Minnesota, New York and Philly in the standings.Here’s how the lottery balls would have been distributed in each of the past 10 seasons.4For 2012, which was shortened by a labor dispute, I’ve prorated loss totals to an 82-game schedule. On average, the worst team would have had about a 25 percent chance of winding up with the top pick, as it does now. But those chances would have been as high as 38.5 percent (for the record-setting 2012 Charlotte Bobcats) or as low as 19.0 percent (for the 2013 Orlando Magic), depending on how much separated the very worst team from the almost-as-bad ones. In a year like 2010, in which there was a big gap between the second-worst team (the 15-67 Timberwolves) and the third-worst (the 25-57 Sacramento Kings), that’s where the sharpest break in lottery chances would have been.It’s not the radical change that I’d prefer! But it’s a simple enough reform that even the Knicks couldn’t screw it up.CORRECTION (April 15, 3:36 p.m.): An earlier version of the chart in this post gave the incorrect location of the second-worst NBA team in 2005. At that time, the Hornets were located in New Orleans, not Charlotte.

What wasn’t so unusual — from a franchise that starred in such tragicomedies as Amar’e Stoudemire punching a fire extinguisher and Andrea Bargnani nearly snatching defeat from the jaws of victory — was the Knicks’ poor sense of timing. Having spent most of the season ridding their roster of anyone who could possibly help them win, the Knicks have now won twice in a row.Those two wins could make a lot of difference to the Knicks’ chance of drafting Jahlil Okafor or Karl-Anthony Towns. With one game left for each team, the Knicks are 17-64, a game better than the Minnesota Timberwolves at 16-65. The Philadelphia 76ers have the third-worst record at 18-63.Let’s say each team loses its final game. Under the NBA’s lottery formula, the Timberwolves would have a 25.0 percent chance of landing the first pick, the Knicks would have a 19.9 percent shot, and the Sixers a 15.6 percent chance.That seems like an awfully big difference for teams that are separated by just one or two games in the standings. But it’s how the NBA’s rules work. The number of losses doesn’t matter, only the order of the teams.1The league does, at least, split the difference in the event of ties, so if the Knicks and Timberwolves each finish at 17-65, they’ll each have about a 22.5 percent chance at the first pick.There’s a better way to award those pingpong balls, one that maintains the spirit of the current lottery system without allowing a one-game difference to matter so much.Here’s how it works. Take each team’s number of losses. Subtract 41 (41-41 represents a breakeven record in the NBA). Then square the result. That’s how many pingpong balls a team gets. (OK, one more provision: A team gets a minimum of 10 lottery balls, including if it has a winning record.2Otherwise, a team with a winning record would get more lottery balls than a team with a 41-41 record, since subtracting 41 from a number less than 41 and squaring the result would produce a positive number.)That might seem arbitrary — but it produces results that are remarkably similar to the current formula, only fairer. What chance would each team have at the first pick this year, for example? Assuming each team’s final game goes according to the FiveThirtyEight NBA Power Ratings,3Meaning that the Wolves, Knicks and Sixers all lose. that would leave the Wolves with a 22.0 percent chance at the first pick, the Knicks at 20.3 percent and the Sixers at 18.6 percent.

Turned On Share your voice Tulipan has placed the limited-edition product in bars and at events around Buenos Aires, and is sharing the product on social media with the hashtag #PlacerConsentido, or “permitted pleasure.” Tulipan plans to sell the condoms online in the future, TNW reports. “Tulipan has always spoken of safe pleasure, but for this campaign we understood that we had to talk about the most important thing in every sexual relationship — pleasure is possible only if you both give your consent,” Joaquin Campins of BBDO said in a statement. Click for more on the intersection of technology and sex. Tulipan’s unusual rubbers arose, TNW reports, after AHF Argentina, an advocacy organization for people living with HIV, revealed that only 14.5% of Argentinian men regularly used a condom. While 65% said they occasionally used condoms, an alarming 20.5% said they’d never used a condom. Many on social media applauded the message tucked into the marketing, though some noted the types of people who commit sexual assault wouldn’t pay attention to it.This isn’t the first creative product to highlight issues around sexual boundaries. The Dress For Respect measures how many times the wearer is groped, with sensors sewn in that measure where on the body, and when, the wearer is touched. The information gets transferred via Wi-Fi to a control unit in real time. The conceptual frock by advertising agency Ogilvy got a test run last year in Brazil, where 86 percent of women have been harassed in nightclubs, according to data from Think Olga, a feminist collective founded by a Brazilian journalist. Three women wore the sparkly conceptual dress to a Sao Paulo club in one night, and the data showed they were touched nonconsensually 157 times in less than four hours. That averages more than 40 touches per hour. Comments 4 Tulipan Two hands aren’t enough to open the package for the new “Consent Pack” of condoms. It takes four hands pressing simultaneously on all four sets of buttons on the top and sides of the box. “If they don’t say yes, it means no,” the tagline on a video demonstration reads. Ad agency BBDO Argentina created the “Consent Pack” for Tulipan, an Argentine seller of sex toys and sexual-health products, including condoms. You probably won’t find this unusual condom in a drugstore near you anytime soon, but it’s still a reminder of the importance of consent in any sexual encounter. It’s a topic that’s gotten increasing attention on college campuses and workplaces in the US amid the #MeToo movement. “Why can’t this box be opened with two hands? Because that’s how consent works in relationships,” reads a translated post from Tulipan’s Facebook page.

On July 25 the Baltimore City Council’s Judiciary and Legislative Investigations Committee voted 5-2 to amend the council’s ill-fated attempt to impose a mandatory minimum one-year sentence on anyone “illegally” carrying a gun within 100 yards of a school, public park, church or any other public facility in the city.The revised bill would impose the one-year sentence only on those committing a second gun possession offense or carrying a gun in commission of a crime against a person or property. Ultimately, the amended measure would be neutralized by existing Maryland law.The response to the original proposed legislation was fast, furious and decidedly negative in many of the city’s mostly Black, mostly poor communities. However, the council’s actions to gut the bill may have avoided a catastrophe similar to what we witnessed in April 2015 following the death (some say murder) of Freddie Gray.Sean Yoes (Courtesy Photo)This wasn’t just a knee jerk response to the very real crisis of violence and murder this city has endured over the last three years (although many would argue the epidemic of violence has been at a crisis level for decades). There is a tone deaf quality to the argument that implementing a mandatory minimum gun law in Baltimore City would somehow assuage our fears and deter violence.In fact, several people who work at City Hall have asked privately, ”Who advised the mayor on this legislation?“ “Mandatory minimums don’t work,” said Councilman Brandon Scott (D-2nd) during last week’s tumultuous hearing prior to the council committee stripping down the hapless gun law.However, the result of implementing the bill as it was originally crafted would have almost assuredly resulted in hundreds, if not thousands, more arrests by the end of 2017.How many of those arrests would have fallen into the category of “illegal arrests” a term made popular during the days of the nefarious zero tolerance policing implemented by then Mayor Martin O’Malley? There are thousands of Black men, their families and communities that still have not recovered from the zero tolerance policy, which at its zenith, was responsible for the arrest of more than 100,000 people per year for several years, in a city of just over 600,000 people.Many argue, with our city being ravaged by violence and 206 homicides (as of August 2), we are at a very tenuous tipping point in Baltimore. The implementation of a mandatory minimum gun law and its aftermath could have had a similar effect as the bad days of zero tolerance policing, possibly recreating circumstances that sparked the uprising of 2015. We underestimate that potential at our own peril.I guess the original bill could technically be resurrected, but it seems highly unlikely because of the vigilance of several of the council’s youngest and newest members.The “renegade eight,” the eight newest members of the council voted in during last year’s general election, entered the chamber with the hopes of many of the city’s most disenfranchised citizens riding on their shoulders. In these cynical political times punctuated over the last six months by the unprecedented and potentially apocalyptic antics of the 45th president, hope in our political leaders has been hard to come by.Yet, the newest members of the council began their tenures by spearheading the unanimous condemnation of statements made by President Donald Trump, just days prior to his visit to Baltimore in December 2016. The first official action of the council denounced Trump’s “divisive and scapegoating rhetoric, rooted in hate and prejudice.” And the rebuke of Trump came as Mayor Catherine Pugh was preparing to ask the 45th president for much needed federal resources for the city. It was a symbolic gesture of course, but perhaps one that set a critical tone going forward.However, the council’s actions in snuffing out the mandatory minimum gun law was real action taken against what many argue was a really bad bill. And in the process they may have diffused a very volatile situation in our city festering beneath the summer sun.Sean Yoes is the AFRO’s Baltimore editor and host and executive producer of First Edition, which airs Monday through Friday, 5p.m.-7 p.m. on WEAA, 88.9.
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. Credit: Avci et al. ©2017 American Institute of Physics (Phys.org)—In 2015, scientists discovered a new magnetoresistance effect—that is, a new way in which magnetization affects a material’s electric resistance—but hadn’t yet found a promising application for the discovery, beyond the existing technologies. 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.
