Periodic Orbits of Hybrid Systems and Parameter Estimation via AD
Hybrid Systems Parameter Estimation via AD
2015/8/25
Rhythmic, periodic processes are ubiquitous in biological systems; for example,
the heart beat, walking, circadian rhythms and the menstrual cycle. Modeling
these processes with high delity as peri...
Pseudo resonance induced quasi-periodic behavior in stochastic threshold dynamics
Pseudo resonance quasi-periodic behavior stochastic threshold dynamics
2011/7/5
Here we present a simple stochastic threshold model consisting of a deterministic slowly
decaying term and a fast stochastic noise term. The process shows a pseudo-resonance,
in the sense that for s...
Entrainment of marginally stable excitation waves by spatially extended sub-threshold periodic forcing

2011/7/5
We analyze the e ects of spatially extended periodic forcing on the dynamics of one-dimensional
excitation waves. Entrainment of unstable primary waves has been studied numerically for di erent

Integrable Maps Associated Poisson Algebras
2010/4/2
We consider a class of map, recently derived in the context of cluster mutation. In this paper we start with a brief review of the quiver context, but then move onto a discussion of a related Poisson ...
Existence of Almost Periodic Solutions For a Class of Nonlinear Duffing Equations

2009/6/16
In this paper, we discuss the existence of almost periodic solutions for a class of nonlinear
Duffing equations. Some new theorems are established to ensure that the existence

2008/11/28
We study the superposition operators (also called Nemytskii operators) between spaces
of almost periodic functions with values in a complete metric space or in a Banach
space. We establish new resul...
