Gravity waves on a random bottom: exact dispersion-relation
(Taylor & Francis Ltd, 2021-05)
In a recent paper [Cáceres MO, Comments on wave-like propagation with binary disorder. J. Stat. Phys. 2021;182(36):doi.org/10.1007/s10 955-021-02699-0.], the evolution of a wave-like front perturbed by space-correlated ...
Surface wave energy absorption by a partially submerged bio-inspired canopy
(IOP Publishing, 2018-05)
Aquatic plants are known to protect coastlines and riverbeds from erosion by damping waves and fluid flow. These flexible structures absorb the fluid-borne energy of an incoming fluid by deforming mechanically. In this ...
Coexistence of acoustic waves and turbulence in low Mach number compressible flows
(American Institute of Physics, 2019-04-04)
In this work, direct numerical simulations of the compressible fluid equations in turbulent regimes are performed. The behavior of the flow is either dominated by purely turbulent phenomena or by the generation of sound ...
Rapid signaling of strogen to neuronal dendrite spine formation
(Lambert Academic Publishing, 2012)
Estrogens are important regulators of neuronal cell morphology and this is thought to be critical for gender-specific differences in brain function and dysfunction. Dendritic spine formation is dependent on actin remodeling ...
Local generation of love surface waves at the edge of a 2D alluvial valley
(Seismological Society of AmericaUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2018-08-01)
This work deals with the local generation of Love surface waves at the edge of an alluvial valley that is formed by a soft layer with dipping interface. These waves are extracted from the system response due to the incidence ...
The Role of Gravity Wave Drag Optimization in the Splitting of the Antarctic Vortex in the 2002 Sudden Stratospheric Warming
(American Geophysical Union, 2018-07)
The impact of gravity wave drag on the Antarctic sudden stratospheric warming (SSW) in 2002 is examined through a mechanistic middle atmosphere model combined with a variational data assimilation system. Significant ...
Spread of highly localized wave-packet in the tight-binding lattice: Entropic and information-theoretical characterization
(Academic Press Inc Elsevier Science, 2011-10)
The spread of a wave-packet (or its deformation) is a very important topic in quantum mechanics. Understanding this phenomenon is relevant in connection with the study of diverse physical systems. In this paper we apply ...
Local spin: A treatment beyond single determinant wave functions
(Elsevier Science, 2009-01)
This Letter describes a partitioning of the expectation value 〈 over(S, ^) 2 〉 of an N-electron system (molecule, ion, radical, etc.) into one- and two-center contributions. The proposal is valid for both independent and ...
A new experimental model of muscle pain in humans based on short-wave diathermy
(Elsevier, 2019-10)
Background: Experimental models of pain in humans are crucial for understanding pain mechanisms. The most often used muscle pain models involve the injection of algesic substances, such as hypertonic saline solution or ...
Acoustic Far-Field Hypersonic Surface Wave Detection with Single Plasmonic Nanoantennas
(American Physical Society, 2018-12)
The optical properties of small metallic particles allow us to bridge the gap between the myriad of subdiffraction local phenomena and macroscopic optical elements. The optomechanical coupling between mechanical vibrations ...
