Acquired forms of Aplastic anemia (AA) are characterized by T cell‐mediated immune disease resulting in bone marrow (BM) failure and marrow hypoplasia. In these cases, it is a major challenge to modulate autoreactive T cell activity and thereby decrease the pro‐inflammatory cytokine storm. Emerging evidence indicates that extracellular vesicles derived from mesenchymal stem cells (MSC‐EVs) control...
A new method is proposed for the direct time integration method for nonlinear structural dynamics problems. In the proposed method which includes an extensive family of direct time integration, the order of the time integration scheme is higher than the classical methods. This method assumes quadratic variation of the acceleration at each time step. The result obtained from this new higher order method...
Circular base plates are commonly used for cylindrical columns; such as pylons in cabled-stayed bridges, lighting poles, electric power line posts, and even buildings. In some structures a little gap is considered between base plate and foundation. In this case compressive bolts which transmit compressive forces to the foundation are also considered in design of base plate. The purpose of this study...
