A Simple Model of Cell Proliferation of Bacteria Using Min Oscillation
Hidetsugu Sakaguchi, Yuka Kawasaki
A mathematical model of Min oscillation in Escherichia coli is numerically studied. The oscillatory state and hysteretic transition are explained with simpler coupled differential…
Cooperative dynamics in coupled systems of fast and slow phase oscillators
Hidetsugu Sakaguchi, Takayuki Okita
We propose a coupled system of fast and slow phase oscillators. We observe two-step transitions to quasi-periodic motions by direct numerical simulations of this coupled oscillator…
Phase Model with Feedback Control for Power Grids
Tatsuma Matsuo, Hidetsugu Sakaguchi
A phase model with feedback control is studied as a dynamical model of power grids. As an example, we study a model network corresponding to the power grid in the Kyushu region. Th…
Creation and Reproduction of Model Cells with Semipermeable Membrane
Hidetsugu Sakaguchi
A high activity of reactions can be confined in a model cell with a semipermeable membrane in the Schlögl model. It is interpreted as a model of primitive metabolism in a cell. We…
Synchronization in coupled phase oscillators
Hidetsugu Sakaguchi
We make a short review about the synchronization in coupled phase oscillator models. Next, we study the common-noise-induced synchronization among active rotators. At an intermedia…
Self-organization of hierarchical structures in nonlocally coupled replicator models
Hidetsugu Sakaguchi
We study a simple replicator model with non-symmetric and nonlocal interactions. Hierarchical structures with prey-predator relations are self-organized from a homogeneous state, i…
