Partitioning Waves and Eddies in Stably Stratified Turbulence

Atmosphere, 2020
We consider the separation of motion related to internal gravity waves and eddy dynamics in stably stratified flows obtained by direct numerical simulations.

First direct measurement of optical phonons in 2D plasma crystals

, 2009
Spectra of phonons with out-of-plane polarization were studied experimentally in a 2D plasma crystal. The dispersion relation was directly measured for the first time using a novel method of particle imaging.

Dispersive Optical Potential Study for Proton-Nucleus Scattering Using Dispersion Relations [PDF]

مجلة جامعة الانبار للعلوم الصرفة
: Usually in nucleon-nucleon reactions, optical potential is used to study the nuclear structures resulting from these reactions. As this potential during the reaction is subject to dispersion by the nuclei surface as well as the total size of the ...

Lieb Mode in a Quasi One-Dimensional Bose-Einstein Condensate of Atoms

, 2002
We calculate the dispersion relation associated with a solitary wave in a quasi-one-dimensional Bose-Einstein condensate of atoms confined in a harmonic, cylindrical trap in the limit of weak and strong interactions.

Universal Holographic Chiral Dynamics in an External Magnetic Field [PDF]

, 2009
In this work we further extend the investigation of holographic gauge theories in external magnetic fields, continuing earlier work. We study the phenomenon of magnetic catalysis of mass generation in 1+3 and 1+2 dimensions, using D3/D7- and D3/D5-brane ...

Impact of Nonlocality on Group Delay and Reflective Behavior Near Surface Plasmon Resonances in Otto Structure

Nanomaterials, 2021
In this work, we study the effects of nonlocality on the optical response near surface plasmon resonance of the Otto structure, and such nonlocality is considered in the hydrodynamic model.

Colors, magnitudes and velocity dispersions in early-type galaxies: Implications for galaxy ages and metallicities [PDF]

, 2004
We present an analysis of the color-magnitude-velocity dispersion relation for a sample of 39320 early-type galaxies within the Sloan Digital Sky Survey. We demonstrate that the color-magnitude relation is entirely a consequence of the fact that both the

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
