Role of chemical potential in relaxation of faceted crystal structure
chemical potential relaxation faceted crystal structure
2015/10/16
Below the roughening transition, crystal surfaces have macroscopic plateaus, facets, whose evolution is driven by the microscale dynamics of steps. A long-standing puzzle was how to reconcile discrete...
Reactive oxygen species' role in endothelial dysfunction by electron paramagnetic resonance
endothelial dysfunction ex vivo spin trapping porcine tissue
2015/1/19
The endothelium is a single layer of cells lining the arteries and is involved in many physiological reactions which are responsible for vascular tone. Free radicals are important participants in thes...
Role of resonances in nonleptonic hyperon decays
Resonance hyperon decay chiral perturbation theory lie to reduce resonance the resonance saturated
2014/12/22
We examine the importance of resonances for the nonleptonic hyperon decays in the framework of chiral perturbation theory. Lower lying resonances are included in the effective theory. Integrating out ...
Role of photonic bandgap in transverse localization of light in a disordered waveguide lattice
Role of photonic bandgap transverse localization of light disordered waveguide lattice Optics
2012/4/24
The role of a prominent photonic bandgap (PBG) on the phenomenon of transverse localization of light in an evanescently coupled disordered one-dimensional semi-infinite lossless waveguide lattice has ...
The Role of Nonlinear Dynamics in Quantitative Atomic Force Microscopy
Role Nonlinear Dynamics Quantitative Atomic Force Microscopy
2012/2/27
Various methods of force measurement with the Atomic Force Microscope (AFM) are compared for their ability to accurately determine the tip-surface force from analysis of the nonlinear cantilever motio...
The Role of Collective Neutrino Flavor Oscillations in Core-Collapse Supernova Shock Revival
Core-Collapse Supernova Shock Revival Neutrino
2011/7/21
We explore the effects of collective neutrino flavor oscillations due to neutrino-neutrino interactions on the neutrino heating behind a stalled core-collapse supernova shock. We carry out axisymmetri...
Role of quark-interchange processes in evolution of mesonic matter
quark-interchange processes master rate equations mesonic matter
2011/7/20
We divide the cross section for a meson-meson reaction into three parts. The first part is for the quark-interchange process, the second for quark-antiquark annihilation processes and the third for re...
The interpretation of quantum mechanics and of probability: Identical role of the 'observer'
quantum mechanics probability
2011/9/14
The aim of the article is to argue that the interpretations of quantum mechanics and of probability are much closer than usually thought. Indeed, a detailed analysis of the concept of probability (wit...
Modeling bound-to-continuum terahertz quantum cascade lasers: The role of Coulomb interactions
Modeling bound-to-continuum terahertz quantum cascade lasers Coulomb interactions
2011/9/14
Based on an ensemble Monte Carlo analysis, we show that Coulomb interactions play a dominant role in boundto-continuum terahertz quantum cascade lasers and thus require careful modeling. Coulomb inter...
Criteria to define a pair-ion plasma and the role of electrons in nonlinear dynamics
Criteria, pair-ion plasma, ion acoustic wave
2011/8/31
A criterion to define a pure pair-ion (PI) plasma is presented. It is suggested that the lighter elements (like H and He) are more suitable to produce PI plasmas. The observation of ion acoustic wave ...
Role of Azimuthal Energy Flows in the Geometric Spin Hall Effect of Light
Light beam Circular polarization Oblique incidence Lateral shift Transverse energy flow Angular momentum
2011/8/29
In an oblique section of a paraxial beam with angular momentum, the beam center of gravity (CG) is shifted with respect to its position in the normal cross section. We relate this shift with the inter...
The Role of Symmetry and Separation in Surface Evolution and Curve Shortening
Symmetry Separation Surface Evolution Curve Shortening Analysis of PDEs
2011/7/25
Abstract: With few exceptions, known explicit solutions of the curve shortening flow (CSE) of a plane curve, can be constructed by classical Lie point symmetry reductions or by functional separation o...

Generalized Dirac bracket the Poincaré symmetry
2010/12/27
In this article the methods of canonical analysis and quantization that were reviewed in the first part of the series are applied to the case of the Dirac field in the presence of electromagnetic int...
The role of bandstructure in the thermodynamic properties of itinerant metamagnets
thermodynamic properties itinerant metamagnets
2010/11/23
It is known that itinerant metamagnetic transitions can be driven by features in the electronic
density of states. We study the signatures of these transitions in the entropy and speci c heat for a v...
In the present paper, first the mathematical basic properties of the exceptional points are discussed. Then, their role in the description of real physical quantum systems is considered. Most interest...
