In this paper we numerically investigate the effect of relative phase on thestability of temporal bright solitons in a Nano PT- Symmetric nonlinear directionalcoupler (NLDC) by considering gain in bar and loss in cross. We also study the effect ofrelative phase on the output perturbed bright solitons energies, in the range of   0 to 180 . By using perturbation theory three eigenfunctions an...

Context. In a Universe dominated by dark matter, halos are continuously accreting mass (violently or not) and such mechanism affects their dynamical state. Aims. The evolution of dark matter halos in phase-space, and using the phase-space density indicator Q = ρ/σ as a tracer, is discussed. Methods. We have performed cosmological N-body simulations from which we have carried a detailed study of...

We present an overview of the critical issues of current interest in magnetic and magnetoelectronic materials. A broad demonstration of the successful blend of materials synthesis, microstructural evolution and control, new physics and novel applications that is central to research in this field is presented. The critical role of size, especially at the nanometer length scale, dimensionality, a...

Software evolution is an inevitable process when developing a system of any notable size and is the most costly stage in the life cycle of a system. Automating parts of this process will reduce the resources required to carry out this stage of development. We aim to develop a framework that achieves this automated evolution by using Dynamic AOP to encapsulate these evolutionary changes and allo...

the effect of rare earth (re) elements, including ce and la, on the sorption properties of zr-co getters was investigated in this work. the phase evolution, microstructural characteristics of getter powders were studied by means of x-ray diffraction method, scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy (eds). the nanostructured zr3co intermetallic compound has been...
