The Northeast China (NEC) was the most important agriculture areas and known as the Golden-Maize-Belt. Based on observed crop data and crop model, we design four simulating experiments and separate relative impacts and contribution under climate change, planting date shift, and varieties change as well change of varieties and planting date. Without planting date and varieties change, maize yiel...

Variovorax paradoxus KB5, isolated from the inside of Arabidopsis thaliana leaves, showed antibacterial activity against the phytopathogen Pseudomonas syringae pv. tomato DC3000. Here, we report a draft genome sequence of V. paradoxus KB5, which contains a delftibactin-like nonribosomal peptide biosynthetic gene cluster.

where (v,1, ..., v,,) is a given probability vector, and (Xt(x), Yl(x)), ..., (X.(x), Y,(x)) is a permutation of (X1, I71) . . . . , (X, , Y,) according to increasing values of IlXi-x[I, x e R a. When [IXi-xll = H X j x l [ but i < j , X i is said to be closer to x than X~. The consistency properties of m, for special choices of the weight vector (v,,, ..., v,,,) are discussed in Cover (1968), ...

Using a CGE model, PRCGEM, with an updated 2002 I/O table, this paper explores how earnings will be affected in each of 40 separate industries across 31 regions (or 8 regional blocks) of China for the period 2002–07. Labour movement between regions within China is considered. It is found that the direct contribution of WTO membership is small to the whole economy in terms of growth and developm...

Begomoviruses are transmitted by cryptic species of the whitefly Bemisia tabaci complex, often in a species-specific manner. Papaya leaf curl China virus (PaLCuCNV) has been recorded to infect several crops including papaya, tomato and tobacco in China. To help assess the risks of spread of this virus, we compared the acquisition, retention and transmission of PaLCuCNV among four species of whi...

A major problem addressed in railway network planning relates to distinguishing the role of the railway line in the network, and making a reasonable classification of the lines based on their role. Accessibility has been widely used to measure the role of transportation infrastructure in various studies, but few quantitative models for the classification of the role have been presented yet. In ...

China’s Railway Transportation (CRT) is enjoying a time of unprecedented development thanks to huge government investment and a series of aggressive favorable policies.
