Research on modeling and simulation of traction power supply system of guideway rubber-tires train

International Journal of Electrical Power & Energy Systems
Guideway rubber-tires system, also known as Rapid rubber-tires trail (RRT), is a new type of urban rail transit. The train uses rubber tires as running wheels and uses guide rails to achieve steering.

Kindlin Regulates Mechanosensitive Activation and Adhesion Assembly of Integrin beta6

Advanced Science, EarlyView.
Extracellular matrix compliance plays a critical role in the regulation of integrin‐mediated adhesion and cell motility. Here, it is reported that strengthening the kindlin2‐integrin β6 interaction overcomes the dependence on extracellular substrate stiffness and promotes integrin β6‐mediated cell migration.

Aligned Conductive Magnetic Nanofibers with Directional Magnetic Field Stimulation Promotes Peripheral Nerve Regeneration

Advanced Science, EarlyView.
Peripheral nerve injury necessitates alternatives to autografts. This study combines magnetic nanoparticles, oriented PCL fibers, and Ppy to create a conductive, magnetically active scaffold. In vitro and in vivo experiments demonstrated enhanced downstream pathways of calcium signaling, as revealed by transcriptome analysis.

A Touch Enabled Hemodynamic and Metabolic Monitor

Advanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.
