Moving discrete breathers in a β-FPU lattice revisited
(Elsevier, 2022-08)
In this work we revisit the existence, stability and dynamical properties of moving discrete breathers in -FPU lattices. On the existence side, we propose a numerical procedure, based on a continuation along a sequence of ...

The closeness of the Ablowitz-Ladik lattice to the Discrete Nonlinear Schrödinger equation
(Elsevier, 2022-04)
While the Ablowitz-Ladik lattice is integrable, the Discrete Nonlinear Schrödinger equation, which is more significant for physical applications, is not. We prove closeness of the solutions of both systems in the sense of ...

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 ...

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 ...

Simultaneous description of β decay and low-lying structure of neutron-rich even- and odd-mass Rh and Pd nuclei
(American Physical Society, 2022-12)
The low-energy structure and β -decay properties of neutron-rich even- and odd-mass Pd and Rh nuclei are studied using a mapping framework based on the nuclear density-functional theory and the particle-boson coupling ...

Cross-Polarization Control in FSSs by Means of an Equivalent Circuit Approach
(IEEE Computer Society, 2021)
This paper presents an efficient equivalent circuit approach (ECA), based on a Floquet modal expansion, for the study of the co- and cross-polarization in frequency selective surfaces (FSS) formed by periodic arrays of ...

Breather stripes and radial breathers of the two-dimensional sine-Gordon equation
(Elsevier, 2021-03)
We revisit the problem of transverse instability of a 2D breather stripe of the sine-Gordon (sG) equation. A numerically computed Floquet spectrum of the stripe is compared to ana- lytical predictions developed by means ...
