Thin film nanostructuring at oblique angles by substrate patterning
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 ...
The Zanclean megaflood of the Mediterranean – Searching for independent evidence
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 ...
A quantitative framework for exploring exit strategies from the COVID-19 lockdown
Following the highly restrictive measures adopted by many countries for combating the current pandemic, the number of individuals infected by SARS-CoV-2 and the associated number of deaths steadily decreased. This fact, ...
Parametrically driven nonlinear Dirac equation with arbitrary nonlinearity
(IOP Publishing, 2020-01)
The damped and parametrically driven nonlinear Dirac equation with arbitrary nonlinearity parameter κ is analyzed, when the external force is periodic in space and given by f(x) = r cos(Kx), both numerically and in a ...
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 ...
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 ...
Influence of Femtosecond Laser Modification on Biomechanical and Biofunctional Behavior of Porous Titanium Substrates
Bone resorption and inadequate osseointegration are considered the main problems of titanium implants. In this investigation, the texture and surface roughness of porous titanium samples obtained by the space holder technique ...
Breather stripes and radial breathers of the two-dimensional sine-Gordon equation
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 ...
Influence of Degradation Processes in Lead–Acid Batteries on the Technoeconomic Analysis of Photovoltaic Systems
Most technoeconomic feasibility studies of photovoltaic (PV) systems with batteries are mainly focused on the load demand, PV system profiles, total system costs, electricity price, and the remuneration rate. Nevertheless, ...
APERTRACK: A particle-tracking model to simulate radionuclide transport in the Arabian/Persian Gulf
A Lagrangian rapid-response model for simulating the transport of radionuclides in the Arabian (or Persian) Gulf is described. The model is based on a tide model including five constituents, which was solved in advance, ...
