Abstract
We discuss the modeling of selfβtrapping in arrays of evanescently coupled optical waveguides with Kerr nonlinear response, contrasting two different approaches. Our results show that the coupled mode equations describe with good accuracy, in a wide range of the parameter values of physical interest, the gap soliton selfβtrapped solutions that can propagate from beams interfering at Bragg angles.

In this article, a linearity-improving technique for active antennas and arrays, based on spatial power combining, is presented. An auxiliary branch is employed to cancel the radiation pattern at the intermodulation distortion (IMD) components, either in the mainbeam direction for a subarray or in a
A general model for the transfer of ions and molecules between two cells via a gap junction is presented. This constitutes a dynamical system consisting of two connected parts: the dynamics of intracellular concentrations and electrical potentials, and the dynamics of the gating in the gap junction.
The response of a heat exchanger tube, under the excitation of an experimentally determined nonlinear fluid force field, has been simulated via a two-degree-of-freedom analytical model for a rotated triangular array of cylinders ( \(P / D=1 \cdot 375\) ) using an explicit time integration algorithm.
