This paper studies a general notion of flatness in the enriched context: P-flatness where the parameter P stands for a class of presheaves. One obtains a completion of a category A by considering the category F latP(A) of P-flat presheaves over A. This completion is related to the free cocompletion under a class of colimits defined by Kelly. We define a notion of Q-accessible categories for a f...

The fourth party logistics which acts as a new role will increasingly play more and more important functions. In this paper, for a given deformation problems of 4PL providers’ evaluation, We builds up a fourth party logistics evaluating indicator system based on four factors, which are quality, technical abilities, collaboration and price. Besides, we studies the analysis methods of grey correl...

We make a preliminary assessment on the habitability of potential rocky exoplanets around Alpha Centauri B. We use several indexes: the Earth Similarity Index, a mathematical model for photosynthesis, and a biological productivity model. Considering the atmospheres of the exoplanets similar to current Earth’s atmosphere, we find consistent predictions of both the Earth Similarity Index and the ...
