Summary: This paper investigates the contribution of long-range diffusion and diffusive stresses to cellular waves generated during an invasion in soft biological tissues. The mathematical model consists of three coupled nonlinear partial differential equations describing the spatiotemporal evolutions of cell density, extracellular matrix (ECM), and spatial displacements. The study reveals that the stability-instability transition in the system depends on the proliferation rate and long-range diffusion of cells, and the presence of temporal or spatiotemporal perturbations. Analytical solutions are constructed and their existence conditions are provided. The findings show that factors such as long-range diffusive stresses, proliferation, ECM production-degradation, and diffusion significantly modify the wave structure and the number of cells carried.

Summary: The modulational instability of ion-acoustic rogue waves in a three-dimensional magnetized, dissipative plasma consisting of inertial warm positive ions and nonextensive electrons has been theoretically investigated. The (3+1)-dimensional modified nonlinear Schrodinger equation (mNLSE) including the dissipative term is derived and solved to obtain instability criteria and rogue wave solutions. The results reveal that increased viscosity leads to energy dissipation, resulting in shorter and thinner ion-acoustic rogue waves.
