SAN FRANCISCO, April 4 (Xinhua) -- Google Inc. on Monday announced that it is bidding for patent portfolio of Nortel Networks in the bankruptcy auction for the Canadian telecommunications equipment maker.In a press release, the Toronto-based Nortel said Google has agreed to buy all of its remaining patents and patent applications for 900 million U.S. dollars in cash.Nortel, which filed for bankruptcy protection in 2009, expects the auction to be held in June this year, pending Canadian and U.S. court approvals.Nortel has selected Google's bid as the "stalking-horse bid," or the starting point against which others will bid prior to the auction.The agreement with Google includes the planned sale of about 6, 000 Nortel patents and patent applications spanning wireless, wireless 4G, data networking, optical, voice, Internet, service provider and semiconductors.According to Nortel, the patent portfolio touches nearly every aspect of telecommunications and additional markets, including Internet search and social networking."This is an unprecedented opportunity to acquire one of the most extensive and compelling patent portfolios to ever come on the market," George Riedel, Nortel's chief strategy officer, said in a statement.Google argued that the bid would help protect it from patent litigation and foster innovation.The technology industry has recently seen an explosion in patent litigation, often involving low-quality software patents, which threatens to stifle innovation, Kent Walker, Google's general counsel, said in a blog post, believing the best defense against such litigation is to have a "formidable patent portfolio. ""So after a lot of thought, we've decided to bid for Nortel's patent portfolio in the company's bankruptcy auction," he said."If successful, we hope this portfolio will not only create a disincentive for others to sue Google, but also help us, our partners and the open source community -- which is integrally involved in projects like Android and Chrome -- continue to innovate," Walker noted.

BEIJING, Jan. 20 (Xinhua) -- Major foreign media have been positive in their coverage so far of Chinese President Hu Jintao's four-day visit to the United States, which began Tuesday.AP said Obama was lavishing the grandest of White House welcomes on Hu as the leaders of the two powers looked for common ground on economic and security issues without alienating their domestic audiences."I absolutely believe China's peaceful rise is good for the world, and it's good for America," Obama said.The Washington Post said Obama stated several times that the United States does not fear a stronger China and that Washington has no interest in blocking Beijing's emergence as a superpower.Chinese President Hu Jintao speaks at a welcoming ceremony held by U.S. President Barack Obama on the South Lawn of the White House in Washington, the United States, Jan. 19, 2011It also said Hu's visit, in addition to serious policy matters, featured a fair amount of glitz. He arrived at the White House to a 21-gun salute and was sent off with a state dinner.The Wall Street Journal said President Obama is looking to assure Americans that they should not fear China's economic rise, using Chinese President Hu's high-profile state visit to announce job-creating business deals worth billions of dollars to U.S. companies.The two sides played down differences and stressed areas of cooperation, ranging from a plan to cooperate on nuclear security to an extension of the loan of two Chinese pandas to Washington's zoo.CNN said at a joint news conference held by the two leaders, Obama praised a "spirit of cooperation that is also friendly competition." President Hu told reporters the countries' relationship is based on "mutual respect and mutual benefit."Obama stressed common interests between the nations while toasting the Chinese leader at the White House, CNN said.VOA said dozens of business deals this week will increase U.S. exports by more than 45 billion U.S. dollars and increase China's investments in the United States by several billion dollars.AFP said that, during Hu's visit, the United States and China had announced a raft of trade deals worth 45 billion dollars. The deals, spanning sectors as diverse as agriculture, gasification, railways and hybrid buses, would support 235,000 U.S. jobs."The scope of Wednesday's deals were seen as evidence of the rapidly deepening business links between the two countries," AFP said.The Los Angeles Times said in its report that two leaders "unapologetically acknowledged major differences on economic issues and human rights" in a White House summit Wednesday, but also pledged cooperation to stabilize relations between the world's two largest economies.Obama said the United States hoped to benefit from China's "rapid and peaceful" growth, the report said.The Times of India said, "China's President Hu Jintao arrived in Washington on Tuesday on a four-day U.S. visit that is being watched in every capital on the planet."O Estado de S. Paulo, a local daily newspaper in Brazil, quoted President Hu's words, saying that China and the United States "stand to gain from a sound China-U.S. relationship, and lose from confrontation," thus they needed to discard the "Cold War mentality."The newspaper also said the two nations both hoped to take the visit as an opportunity to rebuild mutual trust despite some frictions over the past year.

BEIJING, Jan. 23 (Xinhua) -- Chinese President Hu Jintao's state visit to the United States, during which he reached important consensus with U.S. President Barack Obama on building a cooperative China-U.S. partnership based on mutual respect and mutual benefit, has been closely followed by world media.The visit has drawn "unprecedented" world attention, said Gu Xuewu, director of the Center for Global Studies at the University of Bonn.NEW CHAPTER IN DEVELOPMENT OF CHINA-U.S. TIESCommenting on Hu's visit, which occurred at the beginning of the second decade of the 21st century, Professor Severino Cabral, director of Brazil's China and Asia-Pacific Research Institute, said the visit opened a new epoch for China-U.S. relations.The resumption of dialogue between the world's two major economies, which itself is a significant event, would exert great influence on the new world agenda, and hopefully help eliminate the residual cold war mentality and take bilateral relations to a new era, he said.Chen Kang, professor at Lee Kuan Yew School of Public Policy at the National University of Singapore, said that the joint statement issued by the two sides during Hu's stay -- built upon bilateral efforts to establish a cooperative partnership based on mutual respect and mutual benefit -- is a clear reflection of the two countries' resolution and pragmatic attitude in jointly meeting global challenges.China Press USA, a New York-based Chinese language newspaper, said in an editorial that the two countries' commitment to building an all-round and mutually beneficial, win-win economic partnership, as put in their joint statement, is the greatest achievement that comes out of the meeting between the leaders of the two countries in the economic sphere.Nouvelles D'Europe, a major Chinese language newspaper in France, said in an editorial that Hu's visit yielded fruitful results which are indispensable to world peace and development.In their joint statement, the two countries for the first time defined that China-U.S. partnership is based on mutual respect and mutual benefit. Stable China-U.S. relations contribute to world stability, and a win-win scenario between China and the United States is conducive to a scenario of multi-party-win in a multipolar world, it said.International Daily News, an Indonesian newspaper, said that Hu's visit achieved a historic breakthrough. Their joint statement signaled a new chapter in their "cooperative partnership based on mutual respect and mutual benefit," and Asia is hailing the new orientation of bilateral ties and achievement set up by the leaders of the two countries.

LOS ANGELES, April 3 (Xinhua) -- People with lower levels of vitamin D are more likely to have stiffer arteries and an inability of blood vessels to relax, U.S. researchers have found.This finding also applies to people who are in general good health, according to researchers from the Emory University School of Medicine.The researchers presented their findings on Sunday at the annual American College of Cardiology meeting in New Orleans.Impaired vascular health in correlation with lower vitamin D levels contributes to high blood pressure and the risk of cardiovascular disease, the researchers say.The study involved 554 participants, with the average age of 47 and generally healthy.The average level of 25-hydroxyvitamin D (a stable form of the vitamin reflecting diet as well as production in the skin) in participants' blood was 31.8 nanograms per milliliter. In this group, 14 percent had 25-hydroxyvitamin D levels considered deficient, or less than 20 nanograms per milliliter, and 33 percent had levels considered insufficient, less than 30 nanograms per milliliter.The researchers monitored the ability of participants' blood vessels to relax by inflating and then removing a blood pressure cuff on their arms. To allow blood to flow back into the arm, blood vessels must relax and enlarge -- a change that can be measured by ultrasound. The researchers also made other measurements of smaller blood vessels and examined the resistance to blood flow imposed by the arteries.
