Sixty-five found executed in Syria's Aleppo: activists

BEIRUT (Reuters) - At least 65 people, apparently shot in the head, were found dead with their hands bound in a district of the northern Syrian city of Aleppo on Tuesday, activists said.

The British-based Syrian Observatory for Human Rights, which says it provides objective information about casualties on both sides of Syria's war from a network of monitors, said the death toll could rise as high as 80. It was not clear who had carried out the killings.

Opposition activists posted a video of a man filming at least 51 muddied male bodies alongside what they said was the Queiq River in the rebel-held Bustan al-Qasr neighborhood of Aleppo.

The bodies had gunshot wounds to their heads, and their hands were bound. Blood was seeping from their heads and some of them appeared to be young, possibly teenagers, and dressed in jeans, shirts and sneakers.

The Queiq River rises in Turkey and travels through government-held districts of Aleppo before it reaches Bustan al-Qasr.

"They were killed only because they are Muslims," said a bearded man in another video said to have been filmed in central Bustan al-Qasr after the bodies were removed from the river. A pickup truck with a pile of corpses was parked behind him.

It is hard for Reuters to verify such reports from inside Syria because of restrictions on independent media.

Government forces and rebels in Syria have both been accused by human rights groups of carrying out summary executions in the 22-month-old conflict, which has claimed more than 60,000 lives.

Rebels pushed into Aleppo, Syria's most populous city, over the summer, but are stuck in a stalemate with government forces. The city is divided roughly in half between the two sides.

The revolt started as a peaceful protest movement against more than four decades of rule by President Bashar al-Assad and his family, but turned into an armed rebellion after a government crackdown.

More than 700,000 people have fled, the United Nations says.

REBELS FIGHT KURDS

In the eastern city of Deir al-Zor, insurgents including al Qaeda-linked Islamist fighters captured a security agency after days of heavy fighting, according to an activist video issued on Tuesday.

The fighters freed prisoners from the building, it added.

The video, posted online, showed men armed with assault rifles cheering as they stood outside a building that they said was a local branch of Syria's intelligence agency.

Some of the fighters carried a black flag with the Islamic declaration of faith and the name of the al-Nusra Front, which has ties to al Qaeda in neighboring Iraq. The video also showed tanks, which appeared to be damaged, and a room containing weapons.

The war has become heavily sectarian, with rebels who mostly come from the Sunni Muslim majority fighting an army whose top generals are mostly from Assad's Alawite sect, an offshoot of Shi'ite Islam. Assad has framed the revolt as a foreign-backed conspiracy and blames the West and Sunni Gulf states.

Fighting also took place in the northern town of Ras al-Ain, on the border with Turkey, between rebels and Kurdish militants, the Observatory said.

The insurgents have been battling fighters of the Kurdish People's Defence Units for about two weeks in the area, and scores of people have died in the violence.

Toward 2-D devices: Single-atom-thick patterns combine conductor and insulator

Jan. 27, 2013 ? Rice University scientists have taken an important step toward the creation of two-dimensional electronics with a process to make patterns in atom-thick layers that combine a conductor and an insulator.

The materials at play -- graphene and hexagonal boron nitride -- have been merged into sheets and built into a variety of patterns at nanoscale dimensions.

Rice introduced a technique to stitch the identically structured materials together nearly three years ago. Since then, the idea has received a lot of attention from researchers interested in the prospect of building 2-D, atomic-layer circuits, said Rice materials scientist Pulickel Ajayan. He is one of the authors of the new work that appears this week in Nature Nanotechnology. In particular, Ajayan noted that Cornell University scientists reported an advance late last year on the art of making atomic-layer heterostructures through sequential growth schemes.

This week's contribution by Rice offers manufacturers the possibility of shrinking electronic devices into even smaller packages. While Rice's technical capabilities limited features to a resolution of about 100 nanometers, the only real limits are those defined by modern lithographic techniques, according to the researchers. (A nanometer is one-billionth of a meter.)

"It should be possible to make fully functional devices with circuits 30, even 20 nanometers wide, all in two dimensions," said Rice researcher Jun Lou, a co-author of the new paper. That would make circuits on about the same scale as in current semiconductor fabrication, he said.

Graphene has been touted as a wonder material since its discovery in the last decade. Even at one atom thick, the hexagonal array of carbon atoms has proven its potential as a fascinating electronic material. But to build a working device, conductors alone will not do. Graphene-based electronics require similar, compatible 2-D materials for other components, and researchers have found hexagonal boron nitride (h-BN) works nicely as an insulator.

H-BN looks like graphene, with the same chicken-wire atomic array. The earlier work at Rice showed that merging graphene and h-BN via chemical vapor deposition (CVD) created sheets with pools of the two that afforded some control of the material's electronic properties. Ajayan said at the time that the creation offered "a great playground for materials scientists."

He has since concluded that the area of two-dimensional materials beyond graphene "has grown significantly and will play out as one of the key exciting materials in the near future."

His prediction bears fruit in the new work, in which finely detailed patterns of graphene are laced into gaps created in sheets of h-BN. Combs, bars, concentric rings and even microscopic Rice Owls were laid down through a lithographic process. The interface between elements, seen clearly in scanning transmission electron microscope images taken at Oak Ridge National Laboratories, shows a razor-sharp transition from graphene to h-BN along a subnanometer line.

"This is not a simple quilt," Lou said. "It's very precisely engineered. We can control the domain sizes and the domain shapes, both of which are necessary to make electronic devices."

The new technique also began with CVD. Lead author Zheng Liu, a Rice research scientist, and his colleagues first laid down a sheet of h-BN. Laser-cut photoresistant masks were placed over the h-BN, and exposed material was etched away with argon gas. (A focused ion beam system was later used to create even finer patterns, down to 100-nanometer resolution, without masks.) After the masks were washed away, graphene was grown via CVD in the open spaces, where it bonded edge-to-edge with the h-BN. The hybrid layer could then be picked up and placed on any substrate.

While there's much work ahead to characterize the atomic bonds where graphene and h-BN domains meet and to analyze potential defects along the boundaries, Liu's electrical measurements proved the components' qualities remain intact.

"One important thing Zheng showed is that even by doing all kinds of growth, then etching, then regrowth, the intrinsic properties of these two materials are not affected," Lou said. "Insulators stay insulators; they're not doped by the carbon. And the graphene still looks very good. That's important, because we want to be sure what we're growing is exactly what we want."

Liu said the next step is to place a third element, a semiconductor, into the 2-D fabric. "We're trying very hard to integrate this into the platform," he said. "If we can do that, we can build truly integrated in-plane devices." That would give new options to manufacturers toying with the idea of flexible electronics, he said.

"The contribution of this paper is to demonstrate the general process," Lou added. "It's robust, it's repeatable and it creates materials with very nice properties and with dimensions that are at the limit of what is possible."

Illinois Gov. signs bill into law allowing driver's licenses for ...

Illinois Governor Pat Quinn signed a bill into law today that grants hundreds of thousands of?undocumented?immigrants the right to drive. The new law makes Illinois the fourth state to allow driver?s licenses or permits for undocumented immigrants and comes ahead of President Obama?s ?expected announcement on a plan for?comprehensive immigration reform expected on Tuesday.

Quinn and the?bipartisan supporters of the legislation say the measure will improve traffic safety in the state. ?This common sense law will help everybody, regardless of their background, learn the rules of the road, pass a driving test and get insurance,??Governor Quinn said. Despite the stalemate on immigration reform in Washington D.C., Illinois is moving forward. As a result, our roads will be safer, we will create more access to job opportunities and our economic growth will be strengthened.?

For Illinois residents such as Eugenia Flores, a 41-year-old undocumented immigrant from Mexico, the new law could provide protection from criminal prosecution.?Currently, if undocumented immigrants decide to get behind the wheel, a routine traffic stop could lead to fingerprinting and possible?deportation.

?I?m a good driver,? says Flores. ?But my kids get scared when the police stop me. They don?t want me to drive anymore. But I tell them I have to because who will take them to school??

Proponents of the controversial?law, including Chicago Mayor Rahm Emanuel, count about 250,000 undocumented immigrants in the state who drive without licenses. These untrained and untested drivers lead to crashes and higher insurance costs for other motorists, with unlicensed immigrant drivers accounting for around $64 million in damage claims every year, according to the Illinois Highway Safety Coalition.

Unlicensed drivers will continue to drive with or without a license says Lawrence Benito, president of one of the chief?lobbying groups for the bill, the Illinois Coalition for Immigrant and Refugee Rights. ?They have to continue to bring their kids to school or go to church or drive to work,? he says.

The issue has divided lawmakers in Washington, Utah and New Mexico, the only three states that provide identification for undocumented immigrants who wish to drive. The debate has picked up momentum ahead?of federal legislation?that will soon require state driver?s licenses to double as national identification.?Opponents of the measure, including?Governor Susana Martinez of New Mexico,?cite concerns that these types of licenses?will lead to fraud.

In November 2011, two road test instructors?for the Ilinois Secretary of State were indicted for accepting money in exchange for fake driver?s licenses as part of a crime ring.

Meanwhile, Illinois Representative Dwight Kay argues that the law will lead to an influx of undocumented immigrants to the state.

?Granting individuals who came to our country illegally and giving them a benefit sends the wrong message,? Kay said in a statement after the Illinois House passed the legislation. ?A driver?s license is a privilege ? not a right, giving illegals the privilege to drive in our state legally when they broke our laws to come here is bad public policy. We must follow our Constitution and not pass laws based on whichever way the wind blows.?

Applicants for the license must provide a form of identification such as a passport, as well as proof of Illinois residency. ?License holders won?t be able to purchase firearms, fly on commercial planes or vote -?the card can only be used for driving. But, for Eugenia Flores, that privilege is more than enough.

?I don?t want to spend my life just inside my house,??says Flores. ?When the police stop you, you feel like a criminal. Now, I can feel free.?

Israeli Official Hints Pentagon Plans May Make Lone Strike On Iran Unnecessary

New York Times:

JERUSALEM ? Israel?s departing defense minister, Ehud Barak, said that the Pentagon had prepared sophisticated blueprints for a surgical operation to set back Iran?s nuclear program should the United States decide to attack ? a statement that was a possible indication that Israel might have shelved any plans for a unilateral strike, at least for now.

Japan to start 4K TV broadcast in July 2014 - Channels Television ...

The Japanese government is set to launch the world?s first 4K TV broadcast in July 2014, roughly two years ahead of schedule, to help stir demand for ultra high-definition televisions, the Asahi newspaper reported on Sunday without citing sources.

The service will begin from communications satellites, followed by satellite broadcasting and ground digital broadcasting, the report said.

The 4K TVs, which boast four times the resolution of current high-definition TVs, are now on sale by Japanese makers including Sony Corp (6758.T), Panasonic (6752.T) and Sharp Corp (6753.T). Other manufacturers include South Korea?s LG Electronics (066570.KS).

Japan?s Ministry of Internal Affairs and Communications had aimed to kick-start the 4K TV service in 2016. That has been brought forward to July 2014, when the final match of the 2014 football World Cup is set to take place in Brazil, the Asahi report said.

In Japan, the development of super high-definition 8K TVs is in progress, and the Ministry of Internal Affairs and Communications plans to launch the test 8K TV broadcast in 2016, two years ahead of schedule, it said.

The following is a guest post. Enjoy!

No one likes to be in debt, but?taking out personal loans from time to time?is often necessary, especially if the loan is for an investment ? e.g. to buy a first house, finance your education, or get a start-up business off the ground.??? There are well-documented problems that borrowers can encounter with high-interest loans, whether that is caused by poor financial management, or taking out a reasonable loan but not understanding the terms. Even if we are unable to pay a loan back as quickly as we had initially agreed, there is help available for borrowers to consolidate their debt and get out from underneath it. In certain states and counties, debtors who get behind on their payments can actually wind up in private prisons run by contractors, even though debtors? prisons have been mostly illegal in the USA since the Civil War. However, if you find yourself blessed with friends or family who have disposable cash to hand (and like you), there is a great temptation to take a loan from a personal acquaintance instead of a bank or lending institution. And, it makes sense: it's often quicker and easier, with less red tape and better terms (perhaps your friend or family member has even offered to let you pay back the loan interest-fee), and on a whole, it somehow feels less scary; no paper-work or intimidating payment reminders from the bank. But as they say, buyer beware. The danger with borrowing money from someone you know is that money can become a divisive issue; indeed, it is an issue that has been known to destroy relationships and ruin friendships. In fact, an overwhelming number of marital problems and divorces are down to money-related conflicts, which should serve as a strong caution to even the most amiable friend or relative who might offer you financial help. One major stumbling block with family loans is that people may not be honest with you ? i.e., the money may be more important to them than they initially indicate. The importance of recouping that money, and the lender?s expectations as to how quickly you'll pay them back, often goes unstated. Furthermore, you may take their generosity for granted and assume they'll 'let it slide' or that they'll understand if you can't make your repayments every month. It is easy to allow one month of non-payment turn into two months or four; sometimes, it turns into a year, with the hope or assumption that the loan has been forgiven. It is easy to imagine how this might fracture the relationship. An interesting?study was conducted by Carnegie Mellon University?? we have a tendency, especially in situations where we are borrowing money from a friend or family member, to confuse fairness with self-interest. So at the end of the day, which is more important to you: money or your relationships? How about you all? Would you be willing to give a loan to a family member or have you ever taken out one of these? If so, how did it work? Did it create any family stress? Did you have a written agreement?

Economic Change Means Communication Transformation | Lovell ...

The buzz on Capitol Hill is economic reform, but what impact does the economy have on the public relations sector?

As social media continues to gain legitimacy as a key platform to interact with customers and constituents, companies are experiencing the need for solid communications planning and those with the skills to implement the tactics.??Public relations budgets are increasing?at a rate outpacing the GDP growth.? Despite the negative economic media coverage, many businesses are expanding at a fast pace, so building a brand that can sustain such rapid growth is of utmost importance.?

The focus on economy and?legislation?aimed at producing company transparency means many C-level executives are leading their companies from the front lines. The need for solid communications management is critical externally but also internally. ?Most business leaders aren?t aware of the full scope of the PR/communications function and the breadth of skills their team should have? stated our very own Paula Lovell in a recent?Q &A with Nashville Post. ?It?s not just about media relations. PR is a strategic business function that should coordinate with marketing and sales, and it can have significant impact on the bottom line.?

As a result of this changing landscape, today?s communications professionals ?need to know how to do more than write a press release and post on Facebook. Understanding business, the key components of a company and how it all fits together is crucial to producing solid communications strategies. Communications teams are growing as platforms for messaging increase, so working collaboratively as a team is critical for success as well.? How do PR pros stay in the game during the economic adjustments and thereafter?

  • Watch, listen and read. ?It?s important to stay current on trends. You also have to know the tools available and be able to manage messages/data using them.
  • Be on your guard. ?In a world that speaks 24/7 through social media, you can?t let your guard down.? This means communications professionals are on call 24 hours a day. Be proactive with messaging when appropriate, but also be ready at all times to react.
  • Don?t discard the old skills. It might come as a great shock to some, but there is a world outside of Facebook, Twitter, LinkedIn and Pinterest.? Traditional communication skills are still important.
  • Don?t be afraid. ?The face of communications is changing worldwide as technology advances and cultures evolve.? Embrace the change and allow your imagination to go a little crazy to keep fresh ideas coming!
