Effect of fractional blood flow on plasma skimming in the microvasculature

2017-04-25T10:00:00-04:00

Author(s): Jiho Yang, Sung Sic Yoo, and Tae-Rin Lee
Although redistribution of red blood cells at bifurcated vessels is highly dependent on flow rate, it is still challenging to quantitatively express the dependence of flow rate in plasma skimming due to nonlinear cellular interactions. We suggest a plasma skimming model that can involve the effect o…

2017-04-25T10:00:00-04:00

Author(s): Hisatoshi Katsumata, Keiji Konishi, and Naoyuki Hara
Numerical simulations are performed to demonstrate that proportional-integral control, one of the most commonly used feedback schemes in control engineering, can stabilize propagating wave segments in excitable media to a desired size. The proportional-integral controller measures the size of a wave…

Author(s): Lihong Wang, Jingsong He, Hui Xu, Ji Wang, and Kuppuswamy Porsezian
In this paper, we construct a special kind of breather solution of the nonlinear Schrödinger (NLS) equation, the so-called breather-positon (b-positon for short), which can be obtained by taking the limit λ_{j}→λ_{1} of the Lax pair eigenvalues in the order-n periodic solution, which is generated by…

Kinetic discrimination of a polymerase in the presence of obstacles

Author(s): Ilana Bogod and Saar Rahav

This paper studies the influence of obstacles on the speed and fidelity of RNA copying by a polymerase. The authors observe that while the speed of the copying process depends on the details of the interaction between the obstacle and the polymerase, the fidelity does not.
