Modeling of Spiral Waves Arising in Atrial Fibrillation
The objective of this study is to model spirals arising in atrial fibrillation. Spiral wave fronts, known to cardiologists as cardiac rotors, are responsible for heart arrhythmias. The modeling of the path of the spiral will ultimately assist in understanding why arrhythmias occur and how to treat …

Cellular automata models for excitable media
… operation to simulate the propagation of waves (shock fronts) in excitable media, showing that (for well-chosen masks) the waves obey a linear "speedcurvature" relation with slope given by the predicted diffusion coefficient. The utility of different masks in terms of computational …

Strategies for developing ultrathin, high-density, actively multiplexed neural mapping device
… punctual spatial patterns composed of planar and spiral waves during epileptic stage.

A General Study of the Complex Ginzburg-Landau Equation
… in systems with either focusing and defocusing spiral waves, and the related aging exponents, as well as the auto-correlation exponents, are numerically determined. I also investigated nucleation processes when the system is transiting from a turbulent state to the ``frozen'' state. An extracted …

Rotating Thin Films: the Vortex Fluidic Device
… retrograde to the rotating disk. In parallel, spiral waves appear at the free surface of the film, unfolding prograde to the rotating disk. In the VFD, experiments were conducted under CM, exploring the film development over time, the film thickness and the reaction rate at a steady state of …
