WOODY: College football playoff system is just more of the same

Soon, our long national nightmare with the Bowl Championship Series will be over.

After the 2013 college football season, the BCS will be but a bitter memory.

Then the new national nightmare can begin ? the four-team national championship playoff system.

Those of us who have railed against the BCS are supposed to be thrilled. A playoff system! At long last, reason and sanity have prevailed!

But the emperor has no clothes. This is nothing more than an expansion of the BCS system with a selection committee replacing the convoluted, nonsensical polls and computer ranking methods.

"A four-team playoff doesn't go too far," said Virginia Tech president Charles W. Steger. "It goes just the right amount."

With all due respect to Steger and his colleagues who approved the new system, a four-team playoff doesn't go nearly far enough.

Four teams? OK. Who do you like after the two Southeastern Conference teams destined to be selected each year?

Consider this scenario in 2014 or beyond. Injuries to key players cost Virginia Tech and Virginia consecutive losses to Duke and Maryland.

The key players return. Virginia Tech and Virginia get so hot they obviously belong among the top four teams in the country. But with two bad losses, the selection committee ranks the Hokies and Cavaliers seventh and eighth.

Bye-bye national championship dreams.

Still think a four-team field is the answer?

Of course it isn't. At least eight teams should be included.

The new system, with its selection committee, has been compared to the men's NCAA basketball tournament. But there is a huge difference. In college basketball, underdogs have a chance, as shown by George Mason, Butler and VCU.

In this new football playoff world, four elite teams will be selected, and we know such programs as Boise State, Brigham Young and Houston rarely, if ever, will be among them.

But if Nebraska runs the table in a watered-down Big Ten, hello Cornhuskers in a national semifinal game.

The playoff games will not begin until Dec. 31 or Jan. 1 of each year, leaving the monthlong layoff between the end of the regular season and postseason in place.

No other sport at any level operates with this kind of rust-inducing gap. And please don't mention encroachment on academic commitments and exams as the reason. Don't mention bowl games, either.

College athletics ceded academic integrity arguments when football and basketball teams began playing on almost every night of the week. College baseball teams play 50 to 60 games in three months, costing these student-athletes countless hours of class and study time.

Academic issues seem to matter for football teams only in December and January, when classes aren't even held for at least half those months.

Bowl games have lost importance ever since the BCS title game was created. Even with this faux playoff system, the significance of bowl games will continue to decline.

Unless the college presidents come to their senses before a television deal is cut, we will be stuck with this new albatross for 12 years. Any effort to expand the field will be met with the usual obstinate arguments by coaches, who will claim the four-team symmetry is perfect.

In a way, they will be correct. It does a perfect job of keeping championships, power and money among a select few.

Controversy clarified: Why two insulators together can transport electricity

ScienceDaily (July 3, 2012) ? In 2004, researchers discovered something amazing: If the two materials, SrTiO3 and LaAlO3, both of which are electrical insulators, are joined together, a thin, electrically conducting region is formed at their interface. Over the subsequent three years, a number of hypotheses were proposed to explain this effect, which has led to controversy ever since. "There are conference sessions at which the majority of contributions are about this effect," says Mathilde Reinle-Schmitt, a researcher at PSI and the first author of the work presented here.

Of the various explanations forwarded, effectively only two competing hypotheses have survived. In order to compare their relative merits, an appropriate experiment was performed by scientists at PSI, together with colleagues from the University of Geneva. In addition, scientists from the University of Li?ge have contributed important theoretical insights.

Intermixing or polar catastrophe?

Both substances are complex metal-oxide materials ? so-called perovskites ? with a typical layered structure. In SrTiO3, the structure consists of alternating planes of strontium oxide (SrO) and titanium dioxide (TiO2), while in LaAlO3, they are lanthanum oxide (LaO) and aluminium dioxide (AlO2). The two materials, however, differ in one crucial aspect: In SrTiO3, both planes are electrically neutral, while in LaAlO3 they are alternately positively and negatively charged. The combination of two such materials leads, in the opinion of one school of thought, to the transfer of mobile electrons to the interface between the two materials, thereby making this ultrathin interfacial region conducting. This happens, however, only when the LaAlO3 film is thick enough. Otherwise, the combination of materials remains an insulator. This hypothesis is known as the ?polar catastrophe?. Other researchers are nevertheless convinced that conductivity is created because both compounds are known to combine at their interface and this intermixed material is conducting.

The appropriate experiment

In order to clarify this controversy, the researchers wanted to answer the question, "Is a mixture of the two substances conducting?" Mathilde Reinle-Schmitt says, "We used again SrTiO3 as the substrate, but now, instead of depositing pure LaAlO3 on top of this, we used a mixture of SrTiO3 und LaAlO3 in various proportions and thicknesses and then measured the conductivity. The results were surprising. For thin layers of deposited mixtures, the system was insulating, while for thicker layers the interface was conducting, although the layers themselves were not, just as for pure LaAlO3. What changed was that the mixed layer had to be correspondingly thicker the less LaAlO3 there was in the mixture. This result agrees perfectly with the polar catastrophe hypothesis," says Claudia Cancellieri, PSI scientist and second author of the article. "It would be very difficult to explain these results in terms of intermixing."

Numerous applications in view

Perovskites, the category to which the materials being investigated belong, often have interesting electrical and magnetic properties, some of which have never been observed in any other materials. An additional important property is highlighted by Philip Willmott, leader of the investigating group at PSI, "In contrast to traditional semiconductors used today, different perovskites have a similar crystalline and chemical structure and can thus be easily incorporated together, so that materials with different characteristics can be combined into a single device, such as a superconductor with a material which reacts sensitively to magnet fields, or one which can detect substances in the air." Materials in which the current does not flow in all three dimensions, but in only one or, as here, in two, are also current topics of research that could lead to numerous applications.

US drawdown in Afghanistan includes many trainers

CAMP LEATHERNECK, Afghanistan (AP) ? For today's drill, an instructor explains, the Taliban will be played by U.S. Marines, and the "village" will be just down from the driving practice loop.

An Afghan police officer uses a stick to point out targets to his team on a map drawn in the dirt. They grab their weapons and head out, taking cover behind a berm. A pickup truck drives up. The Afghans take aim and mimic the sound of a machine gun. The Marines tumble out of the vehicle, grabbing their chests as they fall to the ground.

That's a successful day at the U.S. Marine-run Joint Sustainment Academy in southwestern Afghanistan, which has been offering supplementary training on weapons, specialized skills and unit leadership to Afghan soldiers and police since 2009. The Afghans who attend the academy say they learn things that were never taught in their official training: how to handle different weapons and how to organize a patrol or an ambush.

But now, even as U.S. officials talk about their commitment to training and advising Afghan security forces well past 2014, the Joint Sustainment Academy is preparing to shut down.

Officials in the U.S. talking about the need to decrease combat operations in Afghanistan have been much more reticent to highlight one aspect of the drawdown: that plenty of U.S. advisers and mentors are also leaving.

Those who stay will be hopping in and out of a number of Afghan units rather than being embedded with one group ? a move that is being described as a way to get Afghan forces to take more responsibility, but which also follows a string of turncoat attacks this year by Afghan forces against their Western counterparts.

"Someone made the decision, 'OK, I'm going to only have the personnel for this piece,'" said Lt. Col. Mike Cromwell, the director of the academy at a U.S. base in Helmand province, as he watched an Afghan police officer brief trainees on the day's mission. "It just means fewer people. It's part of the overall drawdown."

Cromwell and the 31 other American service members running the academy end their tour at the beginning of 2013, and they have been told they won't be replaced. They say it's an opportunity to pass the torch to the Afghan trainers at the academy. But, Cromwell explains, the academy as it exists on Camp Leatherneck is closing.

The Marines are just hoping that the Afghan army and police see the value in what they've been teaching and incorporate it into their existing training centers at a nearby army base and at a police facility in the provincial capital.

"As we ramp down, those centers are the longer term solutions," Cromwell said.

Training classes have already shrunk at the academy. Last year, the Marine academy trained 2,547 Afghans. Cromwell expects to train less than half that ? about 1,000 ? by the end of this year.

"We may not make that," Cromwell said. And this is even though the academy is focused now on training Afghan soldiers and police to become trainers themselves ? a goal that NATO and U.S. forces say is one of their most important priorities.

Ever since President Barack Obama announced the drawdown of U.S. forces in Afghanistan a year ago, his administration has stressed that it does not mean an abandonment of Afghanistan. Combat troops are supposed to decrease as more forces move into a support role. But less advertised is the fact that the U.S. is also decreasing the number of advisers and trainers it is sending to Afghanistan.

According to an April report submitted to Congress, the U.S. forces that make up most of the mentoring teams that operate alongside Afghan troops are being cut with the idea that other NATO nations will fill the gap.

"The United States provides the (Afghan security forces) with the majority of required mentor teams. The drawdown in U.S. forces will result in a decreased number of partnered units, creating additional requirements for other coalition partners," the report states. The plan is to increase the overall number of advisers, using contributions from other allies. But even though the Americans that make up about 63 percent of the adviser teams have already started leaving, NATO is still working to get commitments from other nations.

"The nations have not finalized how much they're going to provide, and which nations," said Maj. Martyn Crighton, a spokesman for the international military force. He said more than 20 nations had agreed to participate, but few had made firm troop commitments.

The plan is to move from a one-to-one mentor ratio to a "one-to-many" ratio in which small teams of up to 18 specialized advisers jump between Afghan units teaching them specific skills. That also leaves open the possibility of keeping those advisers at more of a distance from Afghan forces ? a move that would not be surprising following the recent rash of "green-on-blue" attacks by Afghan forces. In the most recent such attack, an Afghan police officer turned his weapon on NATO police advisers in Helmand province Sunday, killing three British soldiers.

Helmand and Nimroz province, the area covered by U.S. Marines, has already seen troops start to leave, and bigger reductions are coming. The Afghan commander for the region, Maj. Gen. Saad Malouk, said he expects at least 10,000 U.S. troops to depart the southwestern region in September ? nearly half of the 23,000 announced by the Obama administration.

The general overseeing the two southwestern provinces says the trainer cuts don't worry him.

"We're handing over this part of the training," said Maj. Gen. Mark Gurganus. "We will continue to have security force assistance teams ? out with the different battalions and brigades and with our police ? that will continue to mentor, advise and train as we move forward toward the end of 2014 and potentially beyond."

Gurganus would not confirm exact numbers of U.S. troops leaving his operating area, but said it is "significant." U.S. spokesmen would not say exactly how many U.S. mentors are leaving.

The U.S. also has already started decreasing its role in the formal training that all Afghan soldiers and police must undertake. U.S. troops under what's called the NATO Training Mission in Afghanistan started drawing down from 3,300 troops this winter and will continue to decrease through the fall, said Lt. Col. Tim Stauffer, a spokesman for the training mission.

There are about 2,500 U.S. troops under the training mission banner, and that will be cut by about 7 percent by the end September, he said.

"As we're building the capacity for the Afghans to be able to train themselves, the natural next step would be for us to reduce our footprint, and as a result the Afghans would be able to stand on their own and conduct their own training," Stauffer said.

But it's unclear if the Afghan government has the drive to maintain or build on the type of intensive training being provided by coalition troops. An elite military academy is in the works in Kabul, but it won't be up and running until 2013, and then it's hard to know how helpful it would be.

Gurganus noted that a major barrier to additional training is finding the time to take Afghan soldiers out of combat. And the men who have gone through the specialty academy at Leatherneck say they've learned skills from the Marines that go far beyond any Afghan offerings.

"In regular training, we only learned how to use a Kalashnikov and a pistol. Here we learn different weapons. We also learn driving skills, ambush tactics, how to read a map," said Azizularahman Habibi, a 21-year-old police officer serving in Helmand's Nawa district. "We learn to look at the weather, the terrain, where the friendly and unfriendly forces are, how to execute a plan step by step. I had never done any of this before."

NVIDIA projects mobile SoC GPU performance to surpass Xbox 360 by 2014

NVIDIA projects mobile SoC GPU performance to surpass Xbox 360 by 2014

Granted, we hope to see a new Xbox before 2014, but if NVIDIA has its way, mobile devices will have enough graphical prowess to surpass the current generation of gaming consoles by that time. The company brought the smackdown today with a chart that combines both historical and projected data, and while we don't recall NVIDIA exiting the desktop market in 2010, it reinforces the idea that smartphones and tablets of the future may stand as thoroughly enviable gaming devices -- provided that developers are willing to create enough visuals to make these things sing.

HTC One S for T-Mobile review

Image

A couple weeks ago we got to have our Ice Cream Sandwich and eat it too, thanks to a gorgeous couple phones from HTC -- the One X and the One S. Both run Sense 4 -- a thinner, lighter version of the company's polarizing UI -- and together with the entry-level One V, represent HTC's attempt to make a comeback after a lackluster year of me-too products. The first to make its way to the US is the One S which lands on T-Mobile April 25 for $199 on contract (with a $50 rebate). We just spent a weekend with Magenta's new flagship handset. So how does it compare to the global One S? Find out after the break.

'Killer Joe' Promises To Be A Bloody Good Time

Matthew McConaughey opens up about his hit man character for MTV News' Summer Movie Preview Week.
By Kara Warner

"Killer Joe" is the type of genre film you only need to know a few key details about to be intrigued.

First, Matthew McConaughey plays a crazy contract killer. Second, the plot revolves around a desperate young man (Emile Hirsch) who plots to kill his mother with help from his family (Thomas Haden Church, Gina Gershon), who are asked to offer up their teenage daughter (Juno Temple) as a retainer to hire the hit man. Third, the film landed an NC-17 rating for all its gratuitous violence. Bonus highbrow fact: The seemingly crazy story is based on Pulitzer Prize winner Tracy Letts' award-winning play.

See what we mean about intriguing? When MTV News caught up with McConaughey recently, we asked him to set aside the film's outrageous factors for a moment in order to name a few of his character's redeemable qualities, aside from the killer-for-hire part.

"He keeps to himself until he has to go do his business. He's a very structured guy," McConaughey said. "Everyone understands, on the up-and-up, what his plan is and how he'll go through with it. It's a very clean business, and he doesn't want anyone else to know anything they shouldn't know that could implicate them. He's very, very clean and he's a very good businessman. He just happens to have a job that's kinda heinous and absurd."

The "Lincoln Lawyer" and "Magic Mike" said the fun of the film is in not knowing when to laugh or gasp — or both.

"It's a comedy, but everyone played it straight," McConaughey explained. "It wasn't a comedy where you played the joke. The situations are absurd. It's a bit of a hyper-reality, like in some good Tarantino films — very violent, at the same time it's very funny. It's the kind of late laugh that you go, 'I'm not supposed to be laughing, but I just found myself laughing, and is it OK for me to laugh at that? 'Cause I just did.' I like it."

It's Summer Movie Preview Week, and MTV News will be bringing you exclusive interviews, clips and photos for the most anticipated summer movies. Get ready to gorge on inside looks at "The Avengers," Robert Pattinson's "Bel Ami," Kristen Stewart's "Snow White," "The Amazing Spider-Man" and more!
