Fighting AIDS

China’s Health Ministry detailed a plan to fi ght co-infection of HIV and tuberculosis(TB) on August 3.

A ministry circular to health authorities across China said TB infection had become one of the leading causes of death among people living with HIV.

The ministry ordered HIV/AIDS prevention and control authorities nationwide and those responsible for fi ghting TB to step up cooperation in data sharing and testing.

The ministry ordered free treatment and follow-up visits to patients co-infected with HIV and TB once detected.

t分布隨機(jī)近鄰嵌入算法（t-Distributed Stochastic Neighbor Embedding，t-SNE）是 Laurens于2008年提出的基于SNE的改進(jìn)降維算法[13]。t-SNE將位于N維空間中的高維數(shù)據(jù)向量X1，…，Xn映射到D維空間中的低維向量Y1，…，Yn。其中yi與xi一一對(duì)應(yīng)，使得低維空間中數(shù)據(jù)的分布可以反映出高維空間中數(shù)據(jù)間的關(guān)系。t-SNE的基本原理是將高維和低維空間中數(shù)據(jù)點(diǎn)之間的歐氏距離分別轉(zhuǎn)換為兩個(gè)n×n的條件概率矩陣來表示數(shù)據(jù)點(diǎn)間的相似性，然后最小化兩個(gè)概率矩陣間的差別。

It required HIV/AIDS prevention authorities to provide at least one TB examination to people with HIV or AIDS patients every year.

An estimated 700,000 people live with HIV in China. In 2008, China reported that AIDS had become the country’s leading lethal infectious disease for the first time.

Education Loopholes

The Internet is the most important source of information about sexual knowledge for Chinese teenagers, as sex education at school and home is inadequate, according to a survey.

More than three quarters of the survey’s 3,000 teenage respondents said the Internet is their most important source of information about sex. Books and friends were the next most important. School and parents ranked as the two least important sources.

The China Youth Daily newspaper conducted the survey. Still, 71 percent of the respondents believed obscene content on the Internet disturbs teenagers.

Panda Boom

“Altogether 1,206 giant pandas are living in the mountains of Sichuan, making up at least 76 percent of China’s total,” the provincial forestry department said in a press release on August 2.

The endangered bears are found in 10 city and prefecture areas, it said. Another 246 pandas are living in captivity at the giant panda protection and research center in Wolong and the Chengdu research base,the world’s two largest centers for arti ficial breeding of the bears.

Sichuan has 41 nature reserves for giant pandas covering 2.34 million hectares in total.

Property Market

China provided 56,000 hectares of land for residential use in the first six months of 2010, up 135 percent over the same period last year, according to the Ministry of Land and Resources.

A signi fi cant increase in the availability of land for housing was reported in areas like Beijing Municipality, Guizhou, Jiangxi,Heilongjiang provinces and the Ningxia Hui Autonomous Region, said a statement on the ministry’s website.

China implemented a series of measures to rein in soaring home prices and curb property market speculation in April.The measures included tighter scrutiny of applications for fi nancing, limiting of loans for third-home purchases and higher down payments for buying secondhomes.

Latest data indicated the red-hot property market has started cooling as average housing prices in 70 major cities fell 0.1 percent in June from May.

Protecting Workers

The Chinese Government has begun to solicit public opinion on a set of draft regulations on the management of foreign labor service cooperation agreements that aim to protect workers sent overseas.
