We observe that the presence of nonisochronicity parameter leads to structural changes in the chimera death region while varying the strength of the…

The process of memory recall has been studied using autoassociative networks such as the Hopfield model. This kind of model reliably converges to stored patterns that contain the memory. However, it is un…

We discuss the dynamics of a membrane interacting hydrodynamically with an active wall that exerts random velocities on the ambient fluid. Solving the hydrodynamic e…

The stress tensors are found to be similar, suggesting a common drag reducing mechanism in the onset regime for both flexible polymers and rigid fibe…

]]>This paper revisits the classic problem of ionic species passing through a charged channel. The authors introduce several assumptions that simplify the problem and, as a result, are able to produce a full solution for the three-dimensional fluid and ion profiles. As an application of the theoretical approach, the paper analyzes the performance of a reverse electrodialysis device.

For this purpose, we specified the kinetics of tRNA decoding and the corresponding energy landscape, from which we calculated the steady-state decoding rate ${R}_{C}$. Following our work, Xie reexam…

Here, we relax this standard assumption and consider the question of the efficiency fluctuations for a…
