1Precise orbit determination of Beidou Satellites with precise positioning显示文摘Chinese Beidou satellite navigation system constellation currently consists of eight Beidou satellites and can provide preliminary service of navigation and positioning in the Asia-Pacific Region.Based on the self-developed software Position And Navigation Data Analysis(PANDA) and Beidou Experimental Tracking Stations (BETS),which are built by Wuhan University,the study of Beidou precise orbit determination,static precise point positioning (PPP),and high precision relative positioning,and differential positioning are carried out comprehensively.Results show that the radial precision of the Beidou satellite orbit determination is better than 10 centimeters.The RMS of static PPP can reach several centimeters to even millimeters for baseline relative positioning.The precision of kinematic pseudo-range differential positioning and RTK mode positioning are 2-4 m and 5-10 cm respectively,which are close to the level of GPS precise positioning.Research in this paper verifies that,with support of ground reference station network,Beidou satellite navigation system can provide precise positioning from several decimeters to meters in the wide area and several centimeters in the regional area.These promising results would be helpful for the implementation and applications of Beidou satellite navigation system.SHI Chuang ZHAO QiLe LI Min TANG WeiMing HU ZhiGang LOU YiDong ZHANG HongPing NIU XiaoJi LIU JingNan 2012Science China Earth Sciences2012,55,7:61

5Isolation of candidate R disease resistance genes from rice显示文摘Using a polymerase chain reaction (PCR) based method six distinct candidate disease resistant gene (R) homologs from rice have been isolated. The rice sequences are organized into two phylogenetic groups with contrasting genomic organization patterns. The first group, represented by a single sequence, Osh359-1, is more similar to non-rice R sequences than to rice ones and has a simple genomic organization. The second group, represented by Osh359-3, contains the remaining five rice sequences. Osh359-3 consists of a multi-gene family. The members of Osh359-3 family are further found to be clustered together in the genome.Yongbiao Xue Dingzhong Tang Yansheng Zhang Weiming Li 1998Chinese Science Bulletin1998,43,6:6
6Transformers in computational visual media:A survey显示文摘Transformers,the dominant architecture for natural language processing,have also recently attracted much attention from computational visual media researchers due to their capacity for long-range representation and high performance.Transformers are sequence-to-sequence models,which use a selfattention mechanism rather than the RNN sequential structure.Thus,such models can be trained in parallel and can represent global information.This study comprehensively surveys recent visual transformer works.We categorize them according to task scenario:backbone design,high-level vision,low-level vision and generation,and multimodal learning.Their key ideas are also analyzed.Differing from previous surveys,we mainly focus on visual transformer methods in low-level vision and generation.The latest works on backbone design are also reviewed in detail.For ease of understanding,we precisely describe the main contributions of the latest works in the form of tables.As well as giving quantitative comparisons,we also present image results for low-level vision and generation tasks.Computational costs and source code links for various important works are also given in this survey to assist further development.Yifan Xu Huapeng Wei Minxuan Lin Yingying Deng Kekai Sheng Mengdan Zhang Fan Tang Weiming Dong Feiyue Huang Changsheng Xu 2022Computational Visual Media2022,8,1:6

8A survey of HIV infection and related high-risk factors among men who have sex with men in Suzhou,Jiangsu,China显示文摘A cross-sectional study using the snowball sampling method was conducted in May 2008 to investigate human immunodeficiency virus (HIV) infection status and related high risk factors among men who have sex with men (MSM) in Suzhou city of Jiangsu province. The researchers carried out a face-to-face questionnaire interview among MSM, and collected their blood samples to test for HIV and other sexually transmitted diseases (STDs). Among the 280 respondents, 91.1% had homosexual acts in the past 6 months and 87.5% had multiple homosexual partners; 46.4% had heterosexual sex in the past 6 months and 33.1% had multiple heterosexual partners. The rate of continued condom use was 44.3% in homosexual sex in the past 6 months, while the rate in heterosexual sex was 33.9%. Laboratory test results showed that the prevalences of HIV and syphilis were 7.1% (20/280) and 15.0% (42/280), respectively, but no HCV-positive person was found. In the multivariate logistic regression model, subjects with a monthly income of more than RMB $ 1,000 (OR=4.83,95% CI=1.44-16.22), subjects who often went to bars for sexual partners (OR=2.25, 95%CI=1.21-4.20), and subjects who had more than one sexual partner in the past 6 months (OR=0.49, 95%CI=0.25-0.97) and had sex with fixed sexual partners in the past 6 months (OR=0.42, 95%CI=0.25-0.75) were significantly associated with the rate of continued condom use in homosexual sex in the past 6 months. Unprotected sex and multiple sexual partners were more common among MSM in Suzhou city; furthermore, the prevalences of HIV infection and syphilis were relatively high. HIV preventive measures should be designed to address these risk factors and control the spread of HIV among MSM.Hongling Bai Xiping Huan Weiming Tang Xin Chen Hongjing Yan Xiaoyan Liu Haitao Yang Zhihang Peng Xiuping Zhao Rongbin Yu Hao Yu Feng Chen 2011The Journal of Biomedical Research2011,25,1:2

19Local adaptive segmentation algorithm for 3-D medical image based on robust feature statistics显示文摘Medical image segmentation is of pivotal importance in computer-aided clinical diagnosis. Many factors, including noises, bias field effect, local volume effect, as well as tissue movement may affect the medical image, thus causing blurring or uneven characteristics when forming a picture. Such quality defects will inevitably impair the gray-scale difference between adjacent tissues and lead to insufficient segmentation or even leakage during tissue or organ segmentation. In the present investigation, a local adaptive segmentation algorithm for 3-D medical image based on robust feature statistics(LARFS) was proposed. By combining segmentation algorithm principles for traditional region growing(RG) and robust feature statistics(RFS), the location and neighborhood image information of input seed point can be comprehensively analyzed by LARFS.Results show that, for different segmentation objects, under controlling the input parameter of growing factor within certain range, LARFS segmentation algorithm can adapt well to the regional geometric shape. And because the robust feature statistics is applied in the contour evolution process, LARFS algorithm is not sensitive to noises and not easily influenced by image contrast and object topology. Hence, the leakage and excessive segmentation effects are ameliorated with a smooth edge, and the accuracy can be controlled within the effective error range.ZHUO ZiHan ZHAI WeiMing LI Xin LIU LingLing TANG JinTian 2014Science China(Information Sciences)2014,57,10:1
