2015/8/25
We investigate the phase response properties of the Hindmarsh–Rose model of neuronal bursting
using burst phase response curves (BPRCs) computed with an infinitesimal perturbation approximation
and ...
A Geometric Model for Mixed-Mode Oscillations in a Chemical System

2015/8/25
This paper presents a detailed analysis of mixed-mode oscillations in the “autocatalator,” a threedimensional,
two time scale vector field that is a chemical reactor model satisfying the law of mass

2015/3/18
This paper developed a DOE-based
automatic process control scheme considering both
observation and modeling uncertainties. The
simulation demonstrates that considering the
uncertainties, automatic...

2014/12/12
Breathing is a vital process providing the exchange of gases between the lungs and atmosphere. During quiet breathing, pumping air from the lungs is mostly performed by contraction of the diaphragm du...
An incompressible 2D didactic model with singularity and explicit solutions of the 2D Boussinesq equations
Inviscid model, singularity explicit solutions 2D Boussinesq equations

2014/4/3
We give an example of a well posed, nite energy, 2D incompressible active scalar equation with the same scaling as the surface quasi-geostrophic equation and prove that it can produce nite time sing...
A geometric model of tube categories
A geometric model tube categories

2010/11/9
We give a geometric model for a tube category in terms of homotopy classes of oriented arcs in an annulus with marked points on its boundary. In particular, we interpret the dimensions of extension gr...

2010/12/6
We compute the quantum isometry group of the finite noncommutative geometry F describing
the internal degrees of freedom in the Standard Model of particle physics. We show that this
provides genuine...

2010/10/29
We consider the concept of a q-circular system, which is a deformation of the circular system from free probability, taking place in the framework of the so-called 'q-commutation relations'. We show ...
