By actively seeding spatial noise onto an otherwise uniform incoherent beam, we demonstrate that the induced modulation instability has a maximum growth at a certain preferential perturbation period, leading to formation ...
WebThe coherent–incoherent interaction is lumped into a Reynolds averaged Navier–Stokes (RANS) eddy viscosity model, and the mean–coherent interaction is analysed via a semi-linear resolvent analysis building on the laminar approach by Mantič-Lugo & Gallaire (2016 J.

The model and the calculations are based on the theory of self-sustained, nonlinear oscillators. It is argued that these systems form an ideal basis for information-encoding processes in biological systems. Authors: Eichwald, C; Kaiser, F
