Article: Scientists have created a way to control a robot with signals from human brain.By generating the proper brainwaves--picked up by a cap with electrodes that sense the signals and reflect a person's instructions--scientists can instruct a humanoid robot to move to specific locations and pick up certain objects. The commands are limited to moving forward,picking up one of two objects and bringing it to one of two locations.The researchers have achieved 94 percent accuracy between the thought commands and the robot's movements. "This is really a proofofconcept demonstration," said Rajesh Rao,a researcher from the University of Washington who leads the project."It suggests that one day we might be able to use semiautonomous robots for such jobs as helping disabled people or performing routine tasks in a person's home." The person wearing the electrode cap watches the robot's movements on a computer screen through two cameras installed on and above the robot. When the robot's cameras see the objects that are to be picked up they pass on the information to the user's computer screen.Each object lights up randomly on the computer screen.When a person wants something picked up and it happens to light up,the brain registers surprise and sends this brain activity to the computer and then to the robot.The robot then proceeds to pick up the object. A similar algorithm is used to decide where the robot will go. "One of the important things about this demonstration is that we're using a 'noisy' brain signal to control the robot," Rao said."That means we can only obtain brain signals indirectly from sensors on the surface of the head,not where they are generated deep in the brain.As a result,the user can only generate highlevel commands such as indicating which object to pick up or which location to go to,and the robot needs to be autonomous enough to be able to execute such commands." In the future,the researchers hope to make the robots more adaptive to the environment by having them carry out more complex commands.

Article: BEIJING, prefix = st1 /China(CNN) ---China's economic growth dropped to 9 percent for 2008, according to numbers released by the government Thursday --- in line with expectations, but still the slowest rate the nation has seen in seven years. Economists are concerned about what the slowdown means for investment in the future, whether new projects will be undertaken in manufacturing companies and in factories. If not, it will translate into more job losses and erase any optimism about a rebound in 2009. Since 2001, Chinahas been used to double-digit growth as consumers buy Chinese goods. However, the export sector was hit hard in late 2008, with December exports down 2.8 percent. Consumer spending has mostly held up in China, as people there do not carry as much debt as their American counterparts and can continue to spend. Consumer confidence, however, is a problem, said Dong Tao, Asia chief economist for Credit Suisse. Infrastructure is the only thing driving the Chinese economy, Dong said. Tens of thousands of Chinese factories have closed, millions of people are looking for jobs and an untold number of migrants who can't find work may be leaving cities for good because of the slowdown, which would have been unheard of six months ago. Fourth quarter numbers showed growth at 6.8 percent. Goldman Sachs predicted 6.5 percent, down from 9 percent in the third quarter. For all of 2008, Goldman Sachs had predicted 8.8 percent, down from 11.9 percent in 2007.

question:
Article: "Hitler and the Germans," an exhibition in Berlin's German Historical Museum which aims to investigate the society that created Hitler, has seen more than 10,000 visitors walk through its doors since opening on Friday. Rudolf Trabold, a spokesman for the museum, said there were 4,000 visitors to the exhibition on the first day alone. People visiting the exhibition said they had waited as long as one and a half hours to get in. Ravi Nair, a 73-year-old Indian visitor, said: "I had to queue for about an hour but it was worth it. The exhibition should help people in democratic countries realize that their vote is very valuable." Trabold said "Hitler and the Germans" was so popular because it was the first exhibition to explain how a man who lived on the margins of society for 30 years, in Vienna's men's hostels, could become an almost mythical leader of the German people. "We are all affected by Hitler, so it speaks to all of us and helps Germans and foreigners to come to terms with the past." Inge Lonning, a 72-year-old tourist from Norway said: "I thought the exhibition was very impressive. I wanted to see it because I experienced the German occupation of Norway as a small child, so it's not just history for me." But not everyone was convinced there was something new to be learned from the exhibition. "So much has been done about this period over the years, it was like, I knew this and I knew that," said Canadian Julien Cayer, aged 28. "I thought I'd find something new but I didn't." There has been widespread concern in the German media that the exhibition could become a magnet for neo-Nazi admirers of Hitler, but Trabold said that although there had been some right-wing extremist visitors, they had not caused any problems.
