Nonlinear Aggregation of Phase Elements on the Unit Circle under Parametric External Fields
Isshin Arai, Tomoaki Itano, Masako Sugihara-Seki
We investigate nonlinear aggregation dynamics of phase elements distributed on the unit circle under parametrically modulated external fields. Our model, inspired by flaky particle…

Numerical-experimental estimation of the deformability of human red blood cells from rheometrical data
Naoki Takeishi, Tomohiro Nishiyama, Kodai Nagaishi +2
The deformability of human red blood cells (RBCs), which comprise almost 99% of the cells in whole blood, is largely related not only to pathophysiological blood flow but also to t…
