The localization of 1-cohomology of transitive Lie algebroids

Science china Mathematics 2006年第2期49卷 277-288页

作者： CHEN Zhuo & LIU Zhangju Department of Mathematics, Capital Normal University, beijing 100037, china School of Mathematical Science, Peking University, beijing 100871, china 1. Department of Mathematics Capital Normal University Beijing 100037 China 2. School of Mathematical Science Peking University Beijing 100871 China

For a transitive Lie algebroid A on a connected manifold M and its representation on a vector bundle F, we define a morphism of cohomology groups rk: Hk(A,F) → Hk(Lx,Fx), called the localization map, where Lx is the adjoint algebra at x ∈ M. The main result in this paper is that if M is simply connected, or H (LX,FX) is trivial, then T is injective. This means that the Lie algebroid 1-cohomology is totally determined by the 1-cohomology of its adjoint Lie algebra in the above two cases.

The preliminary study on nanodiatom in the Taiwan Strait was carried out using transmission electron microscopy (TEM) in February 1995. Thirty-three species of nanodiatom (ecorders in china. The dominant species were Minidiscus comicus Takano and Thalassiosira tenera Proschdinae -- Lavrenko in the northern Taiwan Strait (NTS), Minidiscus trioculatus (F. J. R. ) Hasle and Natvicula climacospheniae both in the southern Taiwan Strait (STS). Abundance of nanodiatom was much more than that of microdiatom (>20 μm), and the abundance of nanodiatom in NTS is higher than that in STS. The highest abundance of nanodiatom was at the depth of 10 m of N33o in NTS, while at the depth of 20 m of S105 in STS. The vertical distribution of nano- and micro-diatom of NCI showed that the peak was at the depth of 30 m.

Risk analysis for the highly pathogenic avian influenza in china's mainland using meta-modeling

A logistic model was employed to correlate the outbreak of highly pathogenic avian influenza (HPAI) with related environmental factors and the migration of birds. Based on MODIS data of the normalized difference vegetation index, environmental factors were considered in generating a probability map with the aid of logistic regression. A Bayesian maximum entropy model was employed to explore the spatial and temporal correlations of HPAI incidence. The results show that proximity to water bodies and national highways was statistically relevant to the occurrence of HPAI. Migratory birds, mainly waterfowl, were important infection sources in HPAI transmission. In addition, the HPAI outbreaks had high spatiotemporal autocorrelation. This epidemic spatial range fluctuated 45 km owing to different distribution patterns of cities and water bodies. Furthermore, two outbreaks were likely to occur with a period of 22 d. The potential risk of occurrence of HPAI in china's mainland for the period from January 23 to February 17, 2004 was simulated based on these findings, providing a useful meta-model framework for the application of environmental factors in the prediction of HPAI risk.

INTRODUCTION Traditional genetic evaluation has successfully applied to beef cattle breeding in last decades. Henderson’s best linear unbiased prediction has been used as the statistical method for the estimated breeding value(VanRaden and Wiggans.1991).The availability of high throughput genotyping technologies and development of the computer technology have enabled more accurate genetic prediction using the massive genomic *** proposed the concept of Genomic selection(Meuwissen et al.

Model calculation of air-sea heat fluxes over ocean area near china with GEOS DAS system

引用

Acta Oceanologica Sinica 1999年第3期18卷 401-411页

作者：周明煜钱粉兰 Natl. Mar. Environ. Forecast. center State Oceanic Administration Beijing 100081 China

The sensible and latent heat fluxes over the ocean area near china were calculated and analyzed by usingthe Goddard Earth Observing System (GEOS) - four-dimensional Data Assimilation System (DAS). The calculated results showed that the sensible heat flux had its large value in winter and autumn , small value in spring and summer overthe ocean area near china. In winter, the sensible heat flux increased distinctly with latitude, and its isolines were verycrowded. Over the ocean area east of Taiwan Province and south of Japan, the direction of isoline was from southwestto northeast. In the South china Sea the sensible heat flux was lower than that of surrounding ocean areas,and its isoline was distributed into a type of an inverted trough. In autumn and winter, the maximum center of latent heat flux appeared over the ocean area northeast of Taiwan Province and south and southeast of Japan, meanwhile, the isoline wasin the direction of southwest to northeast. In spring and summer, the latent heat flux had minimum value in the Huanghai Sea. At the same time, the maximum value center of latent heat flux appeared over the ocean area south of Japan inspring.
