Full models of scalar modulation instability (MI) in optical fibers available in the literature usually involve complex formulations. In this paper, we present a novel approach to the analysis of MI in optical fibers by ...

Second-order based calibration methods have been widely investigated capitalizing on the inherent benefits of the data structure and the decomposition models, demonstrating that second-order advantage is a property that ...

We consider the nonlinear Schrodinger equation epsilon(2)Delta u - V (x) u + | u|(p-1) u = 0, x is an element of R-N, with superlinear and subcritical nonlinearity. Assuming that the potential is radially symmetric ...

This article is devoted to the nonlinear Schrodinger equation epsilon(2)u'' - V(x)u + vertical bar u vertical bar(p-1)u = 0, when the parameter epsilon approaches zero. All possible asymptotic behaviors of bounded ...

We introduce jump processes in R(k), called density-profile processes, to model biological signaling networks. Our modeling setup describes the macroscopic evolution of a finite-size spin-flip model with k types of spins ...

The GaAs n-type delta-doped field effect transistor is proposed as a source for nonlinear optical responses such as second order rectification and second and third harmonic generation. Particular attention is paid to the ...
