Nonlinear instabilities of multi-site breathers in Klein–Gordon lattices
(Wiley online library, 2016)
In the present work, we explore the possibility of excited breather states in a nonlinear Klein–Gordon lattice to become nonlinearly unstable, even if they are found to be spectrally stable. The mechanism for this fundamentally ...

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 ...

The Zanclean megaflood of the Mediterranean – Searching for independent evidence
(Elsevier, 2020)
About six million years ago, the Mediterranean Sea underwent a period of isolation from the ocean and widespread salt deposition known as the Messinian Salinity Crisis (MSC), allegedly leading to a kilometer-scale level ...

Moving breathers in a bent DNA model
(2002)
We study the properties of moving breathers in a bent DNA model with short range interaction, due to the stacking of the base pairs, and long range interaction, due to the finite dipole moment of the bonds within each ...

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 ...

Determination of the Optical Constants of Gold Nanoparticles from Thin-Film Spectra
(American Chemical Society, 2015-04-06)
We determine the optical properties of nanocomposites comprising gold nanoparticles embedded in a titania matrix using spectroscopic ellipsometry. We then apply the spectral representation formalism due to Bergman, to ...

Thin film nanostructuring at oblique angles by substrate patterning
(Elsevier, 2022-04)
It is demonstrated that, besides classical nanocolumnar arrays, the oblique angle geometry induces the growth of singular structures in the nanoscale when using wisely designed patterned substrates. Well-ordered array of ...

Enhanced luminescent solar concentrator efficiency by Foster resonance energy transfer in a tunable six-dye absorber
(Wiley, 2021-06)
Luminescent solar concentrators (LSCs) collect and concentrate the solar irra-diation to generate electricity through the photovoltaic effect. LSCs haveattracted attention due to their concentration factors, their ability ...

Estudio arqueoastronómico de las iglesias de la Asunción en los poblamientos cristianos tras la reconquista de las provincias de Córdoba y Soria
(Real Academia de Córdoba, 2020)
Estudiamos la orientación de las iglesias de la Asunción en Soria (N=73). El grupo del románico de repoblación (N=45, siglos XII-XIII) muestra patrones de orientación solar: 47% de las iglesias se alinean con el sol ...

Three-dimensional modelling of the tidal dispersion of non-conservative radionuclides in the marine environment. Application to 239,240 Pu dispersion in the eastern Irish Sea
(Elsevier, 1999)
A three-dimensional model to simulate the tidal dispersion of non-conservative radionuclides in a marine environment has been developed. The model solves the three-dimensional hydrodynamic equations using normalized s ...
