The mesenchymal stem cells (MSCs) are known as highly plastic stem cells and can differentiate into specialized tissues such as adipose tissue, osseous tissue, muscle tissue, and nervous tissue.The differentiation of mesenchymal stem cells is very important in regenerative medicine.Their differentiation process is regulated by Rubber Doormat signal
Bridge flutter phenomenon presents an important criterion of instability, SIDE BOARD which should be considered in the bridge design phase.This paper presents different bridge flutter methods which can be used to solve the flutter problem.Most commonly used frequency-domain approach is based on the formulation of aero elastic forces with frequency
Building a broadband equivalent circuit model of a transformer is highly significant for studying the characteristics of high-altitude electromagnetic pulse conduction environments in real scenarios and guiding the high-altitude electromagnetic pulse effect tests of power equipment.This paper utilized an impedance analyzer to obtain the port impeda
