Two-dimensional discrete solitons in rotating lattices
(2007)
We introduce a two-dimensional discrete nonlinear Schrödinger (DNLS) equation with self-attractive cubic nonlinearity in a rotating reference frame. The model applies to a Bose-Einstein condensate stirred by a rotating ...

Influence of spacer layer morphology on the exchange-bias properties of reactively sputtered Co ∕ Ag multilayers
(American Physical Society, 2007-09-25)
We have studied the magnetic properties of [Ag(tAg)/Co(1.2nm)]60 multilayers grown in an oxygen atmosphere. Partial oxidation of the Co layers results in the appearance of tAg dependent exchange-bias properties. A strong ...

Optical refractive index and static permittivity of mixed Zr–Si oxide thin films prepared by ion beam induced CVD
(Elsevier, 2007)
Mixed oxides ZrxSi1−xO2 (0bxb1) thin films have been prepared at room temperature by decomposition of (CH3CH2O)3SiH and Zr[OC (CH3)3]4 volatile precursors induced by mixtures of O2 + and Ar+ ions. The films were flat and ...

Biocompatible Silver-containing a-C:H and a-C coatings: A Comparative Study
(SpirngerLink, 2007-04-18)
Hydrogenated diamond-like-carbon (a-C:H) and hydrogen-free amorphous carbon (a-C) coatings are known to be biocompatible and have good chemical inertness. For this reason, both of these materials are strong candidates to ...

Thermal equilibrium and statistical thermometers in special relativity
(American Physical Society, 2007)
There is an intense debate in the recent literature about the correct generalization of Maxwell’s velocity distribution in special relativity. The most frequently discussed candidate distributions include the Jüttner ...

Oxidation tuning in AlCrN coatings
(ScienceDirect, 2007-01-15)
In this work, we have studied the influence of the coating design and composition on the oxidation behavior of AlxCr1−xN (x = 0.70) coatings. In particular, we have studied the effect brought about by the deposition of an ...

Chemical and oil spill rapid response modelling in the Strait of Gibraltar–Alborán Sea
(Elsevier, 2007)
A numerical model that simulates the dispersion of contaminants, including oil spills, in the Strait of Gibraltar–Alboran Sea region has been developed. The hydrodynamic is solved in ´ advance and includes a barotropic ...

Optically Active Thin Films Deposited by Plasma Polymerization of Dye Molecules
(Wiley-Blackwell, 2007-07)
Colored and fluorescent thin films are prepared via polymerization of dye molecules by interaction with a remote plasma of Ar while they are sublimated on a substrate. The films are formed by a crosslinked matrix of fragments ...

Very large stochastic resonance gains in finite sets of interacting identical subsystems driven by subthreshold rectangular pulses
(American Physical Society, 2007)
We study the phenomenon of nonlinear stochastic resonance (SR) in a complex noisy system formed by a finite number of interacting subunits driven by rectangular pulsed time periodic forces. We find that very large SR gains ...
