Cortical and Cytoskeletal Structural Network regulates the Three-Dimensional Traction Forces Exerted by Migrating Amoeboid Cells [PDF]

Biophysical Journal, 2014
Cells exert traction forces, which are necessary to perform their migration. There is still a lack of information regarding the mechanical aspects of cell migration and in particular the quantification of the three-dimensional traction forces exerted during migration and invasion.We use a novel traction force cytometry method to measure the three ...

Collaborative Optimization Method for Multi-Train Energy-Saving Control with Urban Rail Transit Based on DRLDA Algorithm

Applied Sciences, 2023
With the traffic congestion problem deteriorating, people increasingly choose urban rail transit (URT) to travel. Although URT alleviates traffic congestion, the long-term operation of a large number of trains leads to huge energy consumption.
