Nonlinear reaction-diffusion systems are widely employed to study the spatio-temporal chaotic behavior that occurs in excitable media such as cardiac tissue where sufficiently strong perturbations can excite nonlinear propagating waves which can form spiral waves in two dimensions or scroll waves in three dimensions. The numerical simulation of these waves calls for grids that are extremely fin...

In the present study, double-diffusive oscillatory convection of binary mixture, 3He–4He, in porous medium heated from below and cooled above was investigated with stress-free boundary conditions. The Darcy model employed governing system perturbed equations. An attempt made, for first time, to solve these equations by using nonlinear analysis-based truncated Fourier series. influence Rayleigh ...

Electric charge transport of hadronic matter at finite temperature and magnetic field is studied within the linear sigma model. Anisotropic coefficients associated with are estimated both in weak strong regimes using theory approach. In a weakly magnetized medium, effects incorporated through Lorentz force term Boltzmann equation. Strong puts further constraints on motion charged particles Land...
