Reaction-diffusion waves in multiple spatial dimensions advance at a rate that strongly depends on the curvature of wave fronts. These have important applications many physical, ecological, and biological systems. In this work, we analyse dependences travelling fronts single reaction-diffusion equation with general reaction term. We derive an exact, non-perturbative dependence speed arises from...

Considering great benefits brought by massive multiple-input–multiple-output (MIMO) technologies in the Internet of Things (IoT), it is vital importance to analyze new MIMO channel characteristics and develop corresponding models. In literature, various models have been proposed classified with different but confusing methods, i.e., physical versus analytical method deterministic stochastic met...
