Global climate change has greatly influenced the ecosystems in Tibetan Plateau. Many studies focused on direct effects of warming headwater regions by mean temperature, while less investigating its implication for eco-environment. To address this, study discussed spatial-temporal variations bio-related indicators ?0 °C annual accumulated temperature AAT0 and lasting days LDT0, corresponding ?5 ...

This work is motivated by a mobility study conducted in the city of Munich, Germany. The variable of interest is a binary response, which indicates whether public transport has been utilized or not. One of the central questions is to identify areas of low/high utilization of public transport after adjusting for explanatory factors such as trip, individual and household attributes. For the spati...

Early embryonic germ cells in C. elegans and D. melanogaster fail to express many messenger RNAs expressed in somatic cells. In contrast, we find that ribosomal RNAs are expressed in both cell types. We show that this deficiency in mRNA production correlates with the absence of a specific phosphoepitope on the carboxy-terminal domain of RNA polymerase II. In both C. elegans and Drosophila embry...

Serious soil and water loss affects the economy living quality of population in faulted basins. Since 2002, China has carried out large-scale ecological restoration projects karst areas. However, basins have experienced complex climatic changes, which makes it difficult to assess effects quantitatively. Using improved Budyko model, basin factor (n) sediment content (C) were divided into climate...
