Tennis: Del Potro reaches second Rotterdam tennis final

ROTTERDAM: Juan Martin del Potro dispatched Bulgarian youngster Grigor Dimitrov 6-4, 6-4 on Saturday to move into his second straight Rotterdam Open final.

The Argentine winner, seeded second and now the top-ranked player left after Friday's shock elimination of Roger Federer by Julien Benneteau, will play either the Swiss star's conqueror or fifth seed Gilles Simon.

Del Potro, who lost the final to Federer here a year ago, lifted a pair of indoor titles last autumn in Vienna and Basel.

The Argentine fired six aces in his 75-minute win, breaking once per set in his tidy victory in a first meeting with the 21-year-old Dimitrov.

"I'm glad I was able to beat him, he's a newcomer with a lot of potential," said the winner, bidding for his 14th career title as he plays Rotterdam for the second time.

"I used my serve well today."

Del Potro will be playing in his 19th final at the ATP level.

He reached the final hurdle after holding serve in 40 games without a loss.

"I improved my game since the quarter-finals, but if I want to win the title I have to get that little bit better. I need to play at 100 per cent."

Dimitrov had been looking for his second career ATP final after losing in Brisbane last month to Andy Murray.

The Argentine improved to 6-1 this season while Dimitrov dropped to 9-5.

Do separate components sound better than AV receivers?

There's no doubt that the best of today's receivers sound great and come jam-packed with a vast range of features. Even entry-level models paired with a decent 5.1 speaker/subwoofer system can do a fine job, but some buyers aim higher. They may have invested in a 65-inch or larger display, or maybe a video projector and a 120-inch screen. They crave a sound that matches the grandeur of the picture, and they can get that only with separate components like the Outlaw Audio Model 975 Surround Processor and Model 7125 Power Amp.

The Model 975 Surround Processor's feature set is fairly minimalist, which makes it a nice alternative to today's increasingly hard-to-use receivers. The Model 975 was designed to sound good, but if you need USB inputs, 4K upscaling, Audyssey Auto Calibration, Wi-Fi, Air Play, HD Radio, Internet radio, Ethernet, or Bluetooth, the Model 975 won't cut it. True, there are just four HDMI inputs and that might be a deal-breaker for some potential customers, but I love everything else about the surround processor, including its uncluttered front panel. It's a joy to use.

I listened to the 975 with Outlaw's Model 7125 amp, and if you look under the top cover you'll see why no receiver, including lots of $2,000 or $3,000 ones, can match the sound of a well designed dedicated amp. The receivers don't have enough space to house the massive power transformers, power supply capacitors, and heat sinks for the output transistors you see in power amps like the Model 7125.

I auditioned the Model 975/7125 combo with the Pioneer SP-PK52 speaker system, along with a Hsu Research VTF-1 Mk2 subwoofer. I started with a few multichannel DVD-Audio discs, and the sound was far and away the best I've heard in the CNET listening room. The first thing I noticed was the newfound clarity, so my already positive feelings about the Pioneer speakers shot up a few notches! They sounded bigger and more powerful than before, and the better multichannel recordings generated a remarkably seamless, room-filling soundstage. That is, the gap between the front and rear speakers disappeared; the entire room was energized with sound. I could play the system louder, without strain, than I could with the 90-watt-per-channel
Denon AVR-1912 receiver. The Model 7125 is rated at 125 watts per channel, but it sounded considerably more powerful than the wattage numbers would indicate. The 51-pound Model 7125 has power reserves that receivers like the 22.4 pound Denon can never hope to muster. For example, the Model 7125 can deliver 190 watts into all seven channels with 4-ohm-rated speakers! Denon's higher-end $1,200 AVR-3313Ci receiver can deliver 165 watts per channel into easier-to-drive 6 ohm speakers, but it weighs just 26.45 pounds. There's no way the Denon could deliver close to the same power.

If you have a receiver with 5.1 or 7.1 channel outputs on its rear panel, you may not have to buy Outlaw's Model 975 Surround Processor. You can run your receiver (bypassing its internal amps) with the 7125 and radically upgrade your sound. Outlaw also offers a range of more powerful amps, topping out with the 7x300 watt $3,499 Model 7900.

Comparing the Outlaw 975/7125 combo with a Denon AVR-1912 receiver I was surprised by the magnitude of the difference in sound quality. The Denon was fine, but the Outlaws were a lot more transparent, vivid, clear, and powerful.

Outlaw sells direct with a 30-day return policy. If you order the Model 975 ($575) and Model 7125 ($999) together, the discounted price is $1,398.

Vatican Raises Possibility of Early March Conclave

The Vatican raised the possibility Saturday that the conclave to elect the next pope might start sooner than March 15, the earliest date possible under current rules that require a 15-20 day waiting period after the papacy becomes vacant.

Vatican spokesman The Rev. Federico Lombardi said that the Vatican rules on papal succession are open to interpretation and that "this is a question that people are discussing."

"It is possible that church authorities can prepare a proposal to be taken up by the cardinals on the first day after the papal vacancy" to move up the start of conclave, Lombardi said.

He explained that the 15-20 day rule is in place to allow time for the arrival of "all those (cardinals) who are absent" to take part in the conclave in the usual circumstances of convening after a pope dies. But in this case, the cardinals already know that this pontificate will end on Feb. 28 with the resignation of Pope Benedict XVI, and therefore can get to Rome in plenty of time to take part in the conclave, Lombardi said.

The date of the conclave's start is important because Holy Week begins March 24, with Palm Sunday Mass followed by Easter Sunday on March 31. In order to have a new pope in place in time for the most solemn liturgical period on the church calendar, he would need to be installed as pope by Sunday, March 17. Given the tight time-frame, speculation has mounted that some sort of arrangement would be made to start the conclave earlier than a strict reading of the law would allow.

Questions about the start of the conclave have swirled ever since Benedict announced on Feb. 11 that he would retire, the first pontiff in 600 years to abdicate rather than stay in office until death. As a result, his decision has created a host of questions about how the Vatican will proceed, given that its procedures for the so-called "sede vacante" — or vacant seat — period between papacies won't begin with a pope's death.

Lombardi also gave more details about Benedict's final audiences and plans for retirement, saying already 35,000 people have requested tickets for his final general audience to be held in St. Peter's Square on Feb. 27. He said Benedict would spend about two months in the papal summer retreat at Castel Gandolfo south of Rome immediately after his abdication, to allow enough time for renovations to be completed on his retirement home — a converted monastery inside the Vatican walls.

That means Benedict would be expected to return to the Vatican, no longer as pope, around the end of April or beginning of May, Lombardi said.

He was asked if and when the pope would meet with his successor and whether he would participate in his installation Mass; like many open questions about the end of Benedict's papacy, both issues simply haven't yet been resolved, Lombardi said.

US Q4 industrial output stronger than thought: Fed

WASHINGTON: US industrial production fell in January but the final quarter of last year was much stronger than originally thought, the Federal Reserve reported on Friday.

January's production contracted 0.1 per cent, and manufacturing output fell 0.4 per cent.

But industrial production as a whole expanded at a 2.6 per cent annual pace in the October-December 2012 quarter, compared to the previous estimate of just 1.0 per cent, and manufacturing expanded 1.9 per cent, compared to the previous estimate of 0.2 per cent.

That suggested that the initial government estimate of an 0.1 per cent contraction in the economy last quarter could be revised upward.

Manufacturing output in December was revised up to 1.1 per cent and November 1.7 per cent.

January's production was hit mainly by a 3.9 per cent contraction in automotive products, while energy production surged 3.1 per cent.

Why We Walk … and Run … And Walk Again to Get Where We're Going

You have to get to a bus stop to catch the once-an-hour express ... or to a restaurant to meet a friend ... or to a doctor's office. You've got maybe a half a mile to cover and you're worried you'll be late. You run, then you stop and walk, then run some more.

But wait. Wouldn't it be better to run the whole way?

Not necessarily.

A new study by an assistant professor of mechanical engineering at Ohio State University tests the theory that people subconsciously mix walking and running so they get where they need to. The idea is that "people move in a manner that minimizes energy consumption," said the professor, Manoj Srinivasan.

Srinivasan asked 36 subjects to cover 400 feet (122 meters), a bit more than the length of a football field. He gave them a time to arrive at the finish line and a stopwatch. If the deadline was supertight, they ran. If they had two minutes, they walked. And if the deadline was neither too short nor too far off, they toggled between walking and running.

The takeaway: Humans successfully make the walk-run adjustment as they go along, based on their sense of how far they have to go. "It's not like they decide beforehand," Srinivasan said. (Get tips, gear recommendations, and more in our Running Guide.)

The Best Technique for "the Twilight Zone"

"The mixture of walking and running is good when you have an intermediate amount of time," he explained. "I like to call it 'the Twilight Zone,' where you have neither infinite time nor do you have to be there now."

That ability to shift modes served ancient humans well. "It's basically an evolutionary argument," Srinivasan said. A prehistoric human seeking food would want to move in a way that conserves some energy so that if food is hard to find, the hunter won't run out of gas—and will still be able to rev it up to escape predators.

The study, published on January 30 in the Journal of the Royal Society Interface, doesn't answer that question of how we make such adjustments.

Runners: Take a Break if You Need It

The mix of walking and running is also something that nonelite marathoners are familiar with. Covering 26.2 miles might take less of a toll if the runner stops running from time to time, walks a bit, then resumes a jogging pace. "You use less energy overall and also give yourself a bit of a break," Srinivasan noted. (Watch: An elite marathoner on her passion for running.)

One take-home lesson is: Runners, don't push it all the time. A walk-run mix will minimize the energy you expend.

Lesson two: If you're a parent walking with your kid, and the kid lags behind, then runs to catch up, then lags again, the child isn't necessarily trying to annoy you. Rather, the child is perhaps exhibiting an innate ability to do the walk-run transition.

Potential lesson three: The knowledge that humans naturally move in a manner that minimizes energy consumption might be helpful in designing artificial limbs that feel more natural and will help the user reduce energy consumption.

The big question for Manoj Srinivasan: Now that he has his walk-run theory, does he consciously switch between running and walking when he's trying to get somewhere? "I must admit, no," he said. "When I want to get somewhere, I just let the body do its thing." But if he's in a rush, he'll make a mad dash.

"Talk to you tomorrow," he signed off in an email to National Geographic News. "Running to get to teaching now!"

Falling Meteor Causes Blast, Injures Hundreds

A massive meteor shower slammed into Earth near the Russian city of Chelyabinsk, located about 1,000 miles east of Moscow in the Ural Mountains.

Dashboard cameras captured a blinding flash of light streaking across the sky. Moments later, the fragments smashed into the ground. The impact, and the sonic boom of the meteor entering the atmosphere, shattered windows around the city and knocked over a wall at a zinc factory.

LIVE BLOG: Russian Meteorite Impact; Asteroid Approaching Earth

Witnesses said they thought a war had broken out.

"I saw a body moving in the skies. In a moment there came a flash - we first thought it was fireworks but a moment later we saw a trace as if from the rocket followed by an explosion in a couple of minutes. The window broke ... tea, bread, water - everything fell on the floor," one restaurant waiter in Chelyabinsk said.

Officials told the Russian news agency Interfax that more than 500 people were injured, most by broken glass. Of the 12 people hospitalized, at least three of them were in serious condition.

SEE PHOTOS: Meteorite Crashes in Russia

One scientist told Russian television the meteor was a big one, weighing perhaps tens of tons, but stressed that it was not related to the asteroid that is expected to buzz close to Earth later today.

Regional officials said the one large fragment fell in a lake, but debris had been reported in three parts of Russia and in Kazakhstan.

Schools in the region closed for the day after most of the windows were blown out, citing freezing temperatures, which were below zero degrees Fahrenheit during the day.

Debris from the meteor was found in three sites around the country, but emergency services say ground zero was Chebarkul Lake, just west of Chelyabinsk.

The meteor knocked out cell phone networks, but electricity and water supplies were not affected. Rosatom said all its nuclear power facilities were functioning normally.

Mumbai attack movie hits cinemas on Mar 1

MUMBAI: Memories of the Mumbai terror attacks of November 2008 still evoke fear among residents of the city.

And those old wounds are expected to reopen now that a Bollywood movie about the incident is set to hit the big screens.

India's financial capital came to a virtual standstill on 26 November 2008.

The attacks which lasted for four days drew widespread global condemnation.

The Pakistan-based terrorists, who were members of Lashkar-e-Taiba, killed 164 people and wounded at least 308 in their wake.

But the undying spirit of the citizens of Mumbai helped the city crawl back to its feet soon after the carnage ended.

And now, Bollywood is all set to release a film which will depict the gruesome terror attacks that shook Mumbai nearly five years ago.

The movie "The Attacks of 26/11" will hit cinemas on 1 March.

A publicity event to launch the movie's music was held at the Gateway of India.

Around 200 students lit candles in memory of the 26/11 victims.

The event then continued at Café Leopold where two of the ten terrorists launched their initial strikes in the first wave of attacks on the city.

Film maker Ram Gopal Varma said: "I strongly believe as a film maker and as a human being that the attacks of 26/11 which happened in 2008 are not against any community in particular. I think it is an attack on human beings and committed by certain inhuman elements."

The mood was sombre as the film maker and lead actor showed off a few teasers from the movie.

The usually reclusive veteran Bollywood actor Nana Patekar, who plays the lead role in the film, shed his inhibitions and spoke to the media with unusual frankness.

He said: "I feel pained whenever I think about the attacks of 26/11. The film depicts the mindset of the terrorists who went on a carnage in Mumbai. We are trying to portray through our films what steps can be taken to prevent such types of attacks in future."

The owner of the Leopold was also present at the event, and has played himself in the film.

The music launch of the film has reignited the anger and bitterness in the minds of Indian citizens.

But as in 2008, the movie also shows the world that Mumbai and its people have picked up the pieces and are refusing to let fear of terror attacks get in the way of their daily lives.

What is the 'Soap Opera Effect'?

Do movies look weird on your new TV? Does everything have a hyper-real, ultra-smooth motion to it? Are you sure something is happening with the TV's image you don't like, but you can't figure out what?

Chances are, what you're seeing is called the "Soap Opera Effect," as descriptive a moniker as we get in tech, in that this feature makes everything on your TV look like a cheap soap opera.

Here's what it is, what it does, and how to turn it off.

The Soap Opera Effect, or SOE, is actually a feature of many modern televisions. It's called "motion smoothing," "motion interpolation," or "ME/MC" for motion estimation/motion compensation. Some people don't notice it, some don't mind it, and a few even like it. From e-mails and article comments I've read, it seems most people hate it.

This motion "whatever" was ostensibly developed to help decrease apparent motion blur on LCDs. All LCD TVs have difficulty with motion resolution. Which is to say, any object onscreen that's in motion will be less detailed (slightly blurry) compared with that same object when stationary. High-refresh-rate LCDs (120Hz and 240Hz) were developed to combat this problem. Check out "What is refresh rate" for a more in-depth description of this. The short version: in order for high-refresh-rate TVs to be most effective, they need new, real frames to insert in-between the original frames.

Thanks to speedy processors, TVs can "guess" what's happening between the frames captured by the camera originally. These new frames are a hybrid of the frame before and the frame after. By creating these frames, motion blur is reduced. With 30fps and 60fps content, this is great. Content like sports have better detail with motion, and there are minimal side effects (beyond errors/artifacts possible with cheaper/lesser motion interpolation processing).

Film
However, with 24fps content (namely Hollywood movies and most nonreality, prime-time TV shows like sitcoms and dramas), there's a problem. The cadence of film, and the associated blurring of the slower frame rate's image, is linked to the perception of fiction. Check out the scathing reviews of the high frame rate version of "The Hobbit" for proof of that. Even if this perception seems grandiose -- the look of 24fps is expected with movies and fiction TV shows. Even though the TV and movie industries have been moving away from shooting on actual film, the new digital cameras are set for 24fps because the audience for fictional programming expects that look.

SOE messes with this cadence. By creating new frames between the 24 original frames, it causes it to look like 30fps or 60fps content. In other words, it makes movies (24fps) look like soap operas (30/60fps). And thus, a name is born.

By any other name
Every TV company has a different name for their motion interpolation processing. A sort list: Sony MotionFlow, Samsung Auto Motion Plus, Sharp AquoMotion, Toshiba ClearFrame or ClearScan, Vizio Smooth Motion, and LG TruMotion. I sense a theme.

While reducing motion blur is the main reason this processing exists, the (possibly) beneficial side effect is reducing the 2:3 judder noticeable on fast pans in 24fps content. The process of converting 24fps content for 60fps televisions involves a 2:3 sequence. The first frame is shown twice, the second frame three times, the third twice, and so on. Check out "1080i and 1080p are the same resolution" for a more detailed description. Because this sequence is, well, weird, camera pans can look jerky or juddery. Motion interpolation smooths this out. This is one of the reasons why some people prefer the SOE.

Nearly all companies allow you to disable SOE, and most allow you to adjust its intensity. Some separate out the blur reduction from the judder reduction, though personally I've found SOE at any level to be distracting.

Plasma
Up until recently SOE has been an LCD-only "issue." In the effort to make plasmas more competitive in a retail store, motion smoothing circuitry has found its way into plasmas. Because plasma TVs don't suffer from the motion blur problems that LCDs have (or at least, not to the extent), motion smoothing is largely superfluous. For that matter, plasmas aren't increasing their refresh rates to insert new frames, so all that's really happening is the TV is creating new frames to insert in-between the film frames, just to make the motion smoother.

Panasonic, for example, calls its version of this Cinema Smoother. On its LCDs, you can find it under "Motion Picture Setting."

This is how Panasonic explains its Cinema Smooth processing. Other company's processing works the similar to this diagram. Note the ' and " signifying the blue-boxed frames are different (interpolated).

Bottom line
The best part about the Soap Opera Effect is if you don't like it, you can turn it off. A few minutes digging though your TV's picture settings, and you should be able to find it. Get to know where this setting is (it's probably on the remote, too). It's possible you'll want it on when you're watching sports, or other "video"-based content (30fps or 60fps). Then, for movies and fictional TV programming, you can turn it off. This will give you the best-of-both worlds approach with minimal motion blur with sports, and no SOE with movies.

With plasma TVs, though, there is little penalty to turning this "feature" off. So go ahead.
