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 ...
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 ...
Ichnological signatures from wave- and fluvial-dominated deltas: The La Anita Formation, Upper Cretaceous, Austral-Magallanes Basin, Patagonia
(Elsevier, 2019-12)
Depositional processes operating in deltaic shorelines create a variety of physico-chemical stressful conditions that impact directly on benthic fauna. The ichnological signatures of deltaic successions reflect these ...
Coronal heating by surface Alfvén wave damping: Implementation in a global magnetohydrodynamics model of the solar wind
(IOP Publishing, 2012-09)
The heating and acceleration of the solar wind is an active area of research. Alfvén waves, because of their ability to accelerate and heat the plasma, are a likely candidate in both processes. Many models have explored ...
