We investigate a box-ball system with periodic boundary conditions. Since the box-ball system is a deterministic dynamical system that takes only a finite number of states, it will exhibit periodic motion. We determine its fundamental cycle for a ...

We propose a box and ball system with a periodic boundary condition periodic box and ball system (pBBS). The time evolution rule of the pBBS is represented as a Boolean recurrence formula, an inverse ultradiscretization of which is shown to be equ...

After reviewing the important roles of excitons in nonlinear optical responses, we demonstrate mutual and quantum-mechanical control of radiation field and excitons on the same footing in a microcavity. First we introduce dressed excitons as boson...

A two-dimensional mathematical model for dynamics of endothelial cells in
angiogenesis is investigated. Angiogenesis is a morphogenic process in which
new blood vessels emerge from an existing vascular network. Recently a
one-dimensional discrete ...
