In the seasonally frozen regions, railway subgrades are subjected to freeze-thaw cycles due to environmental temperature change.The railway track is likely to be deformed during the freezing and thawing processes of subgrades.As a result, the train operations will be severely affected.In the present study, the track deformation induced by the freez
The accurate regulation of the microenvironment within the nervous system is one of the key features characterizing complex organisms.To this end, neural tissue has to be physically separated from circulation, but at the same time, mechanisms must be in place to allow controlled transport of nutrients and macromolecules into and out of the brain.Th
Abstract Studying the wagon accumulation process and the laws of accumulation cost is of great significance for determining the suitable conditions of wagon accumulation and shortening the accumulation time.Here, the process of relaxed fixed time accumulation is first taken as a stochastic service system, and derives the theoretical formula for the
