Interlaced solitons and vortices in coupled DNLS lattices
(2009)
In the present work, we propose a new set of coherent structures that arise in nonlinear dynamical lattices with more than one component, namely interlaced solitons. In the anti-continuum limit of uncoupled sites, these ...

GISPART: a numerical model to simulate the dispersion of contaminants in the Strait of Gibraltar
(Elsevier, 2005)
GISPART is a three-dimensional particle-tracking code to simulate the dispersion of contaminants in the Strait of Gibraltar. It consists of a hydrodynamic module that is run off-line to determine tidal constants and ...

A rapid response model for simulating radioactivity dispersion in the Strait of Gibraltar
(Springer, 2007)
GISPART (GIbraltar Strait PARticle Tracking model) is a three-dimensional particle-tracking code that simulates the dispersion of radionuclides in the Strait of Gibraltar. It consists of a hydrodynamic module that is run ...

Dynamics of the Davydov-Scott monomer in a thermal bath: comparison of the full quantum and semiclassical approaches
(2007)
The quantum state diffusion equation is applied to the problem of energy transfer in proteins. Lindblad operators, capable of coupling the full quantum Davydov-Scott monomer to a thermal bath, are derived. Numerical ...

Anomalies of ac driven solitary waves with internal modes: Nonparametric resonances induced by parametric forces
(2001)
We study the dynamics of kinks in the φ4 model subjected to a parametric ac force, both with and without damping, as a paradigm of solitary waves with internal modes. By using a collective coordinate approach, we find that ...

Kinetic modelling of the dispersion of plutonium in the eastern Irish Sea: two approaches
(Elsevier, 2003)
A new model to simulate the dispersion of plutonium in the eastern Irish Sea is presented. The model solves the 3D hydrodynamic equations using normalized r coordinates in the vertical simultaneously with the suspended ...

On the ratchet effect
(2005)
Entender el efecto trinquete inducido por la simetría temporal de fuerzas es una cuestión fundamental que ha permanecido sin resolver durante décadas. Mientras la dependencia del transporte dirigido en cada uno de los ...

Wetting Angles on Illuminated Ta2O5 Thin Films with Controlled Nanostructure
(American Chemical Society, 2009)
Ta2O5 thin films with different nanostructure and surface roughness have been prepared by electron evaporation at different angles between the evaporation source and the substrates. Large variation of refraction indexes (n) ...

Positron annihilation and transmission electron microscopy study of the evolution of microstructure in cold-rolled and nitrided FeNiTi foils
(IOPScience, 2001)
Positron beam analysis (PBA) and transmission electron microscopy (TEM) were applied to study structural transformations in cold-rolled Fe0.94Ni0.04Ti0.02 foils, which were subjected to different thermal treatments in an ...

Comparative depth-profiling analysis of nanometer-metal multilayers by ion-probing techniques
(ScienceDirect, 2009-04)
We examine here the depth resolution (interface width) in elemental analysis and depth profiling of complex layer systems of three ion-probing techniques, each of which has pros and cons: • Rutherford backscattering ...
