Research on the Prediction Model of Engine Output Torque and Real-Time Estimation of the Road Rolling Resistance Coefficient in Tracked Vehicles.

Road parameter identification is of great significance for the active safety control of tracked vehicles and the improvement of vehicle driving safety. In this study, a method for establishing a prediction model of the engine output torques in tracked vehicles based on vehicle driving data was proposed, and the road rolling resistance coefficient f was further estimated using the model. First, the driving data from the tracked vehicle were collected and then screened by setting the driving conditions of the tracked vehicle.

MiR-455-5p Attenuates Cerebral Ischemic Reperfusion Injury by Targeting FLT3.

Cerebral ischemia-reperfusion (I/R) injury is a terrible disease which results in the dysfunction and structural damage of brain tissues. Growing evidence implies that miR-455-5p is implicated in the regulation of pathogenesis of several diseases. The aim of this study is to reveal the role of miR-455-5p in cerebral I/R injury and the regulatory mechanism.

Effect of Chit-oligosaccharide/Collagen Composite Gels on Pre-osteoblastic MC3T3-E1s Differentiation.

Chit-oligosaccharide(COS)is a low-molecular,water-soluble mass with higher biological activity,which can be absorbed by human body easily and interact with cells directly.Based on the excellent biological properties of collagen(Col)and COS,a series of Col and COS composite hydrogel(Col/COSn)was constructed in this study.The effect of composite hydrogel on cells proliferation,differentiation and related osteogenic gene expression was evaluated on pre-osteoblast MC3T3-E1 s.
