BEIJING, April 14 (Xinhuanet) -- Computer sales declined in the first three months of this year for the first time since 2009 worldwide.PC sales fell 1.1 percent in the first quarter to 84.3 million worldwide, according to tech research firm Gartner Wednesday, well short of its forecast for 3 percent growth.The dip was the first since the second quarter of 2009, when most of the world was still in the grip of economic turmoil."Although the first quarter is traditionally a slow one for PC sales, these shipment results indicate potential sluggishness, not just a normal seasonal slowdown," said Gartner, in a statement.Consumers select IT products at an IT fair named "Sham Shui Po computer festival" in Hong Kong, south China, Feb. 15, 2011. The eight-day IT fair kicked off here Monday. Some 600,000 people are predicted to visit the fair.Weak demand for consumer PCs was the biggest drag on the market, according to Gartner principal analyst Mikako Kitagawa."Low prices for consumer PCs, which had long stimulated growth, no longer attracted buyers," Kitagawa said."Instead, consumers turned their attention to media tablets and other consumer electronics."After Apple's second-generation iPad was released in February, many consumers either switched allegiances or simply held back from buying PCs, according to the analyst.Japan was a particularly weak spot, with PC sales falling 13 percent in the quarter, as people focused on getting back to normal after the March 11 earthquake and tsunami rather than spending money on new technology.

STOCKHOLM, Feb. 20 (Xinhua) -- The exhibition of the Chinese Terra-cotta Army here was an enormous success, project organizer Sanne Houby-Nielsen said Sunday.About 320 objects, including terra-cotta warriors from the ancient Chinese Qin Dynasty and other terra-cotta figures from Han Dynasty, were exhibited at the Far Eastern Antiquities Museum during the event, which ended Sunday.Houby-Nielsen, who is director of the museum and also director-general of the country's National Museums of World Culture, told Xinhua in an exclusive interview that the total number of visitors was around 350,000, more than double the expected turnout.This was the highest number of visitors the museum has ever experienced in its history since it was established in the 1940s, said Houby-Nielsen, adding that the exhibition was originally scheduled to end on Jan. 16, but "a great pressure from the audiences" prompted the museum to extend it till Sunday."It is an exhibition which won the most audience for many years in Sweden. We feel particularly happy because it was a very good display of the story of the first emperor and the early Han Dynasty," she said."We felt such a huge interest that we have to prolong it. So we were very grateful that it was possible to prolong the exhibition," she added.The exhibition was declared open by Swedish King Carl XVI Gustaf in August. Many of the ancient Chinese artifacts have never been exhibited outside China.Swedish Sinologist Cecelia Lindqvist commented that the event helped people understand the current China by looking at the history of China presented in the exhibition.

JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

BEIJING, May 24 (Xinhuanet) -- The PlayStation Network's shutdown caused by hacker's attack has cost Sony 14 billion Japanese yen, or 171 million U.S. dollars.Sony revealed the figure on Monday as a part of its overall loss in the massive earthquake and tsunami, 3.2 billion U.S. dollars, in the company's fiscal year ending on March 31, 2011.The 171 million U.S. dollars cover the lost revenue, the customer compensations, the security and legal enhancement fees and the free games the company offered as a goodwill gesture.The cyber-attacks, which kept the PlayStation Network offline from April 20 to May 15, involved the theft of personal data from more than 100 million accounts of the gamers.But the crisis was far from over yet."So far, we have not received any confirmed reports of customer identity theft issues, nor confirmed any misuse of credit cards from the cyber-attack," the company said, "Those are key variables, and if that changes, the costs could change."
