The field high-amplitude SX Phoenicis variable BL Camelopardalis: results from a multisite photometric campaign
(EDP SCIENCES, 2007-08)
Context. BL Cam is an extreme metal-deficient field high-amplitude SX Phe-type variable where a very complex frequency spectrum is detected, with a number of independent nonradial modes excited, unusual among the high-amplitude ...
Lithospheric structure of the Chaco and Parana Basins of South America from surface-wave inversion
(American Geophysical Union, 1997-02)
Surface-wave data from a portable broadband array have been used to invert for the velocity structure of the crust and upper mantle beneath the Chaco and Parana Basins of central South America. The upper-mantle velocity ...
Asymptotic-behavior of Jost functions near resonance points for Wigner-Vonneumann type potentials
(AIP Publishing, 1991-01)
In this work are considered radial Schrodinger operators - psi" + V(r)-psi = E-psi, where V(r) = a sin br/r + W(r) with W(r) bounded, W(r) = O(r-2) at infinity (a,b real). The asymptotic behavior of the Jost function and ...
Herschel PEP/HerMES: the redshift evolution (0 <= z <= 4) of dust attenuation and of the total (UV plus IR) star formation rate density
(EDP Sciences, 2013-06)
Using new homogeneous luminosity functions (LFs) in the far-ultraviolet (FUV) from VVDS and in the far-infrared (FIR) from Herschel/PEP and Herschel/HerMES, we studied the evolution of the dust attenuation with redshift. ...
Raman-scattering and optical studies of argon-etched GaAs surfaces
(American Physical Society, 1991-04)
We have studied the structual damage in low-energy argon-ion-bombarded (ion-etched) GaAs using Raman scattering and ultraviolet reflectivity. When combined with post-bombardment sequential chemical etching, the Raman results ...
Bound states of hydrogen atom in a theory with minimal length uncertainty relations
(AIP Publishing, 2007-05)
The following properties of bound states of hydrogen atom in a theory with noncommuting position operators are investigated: their number, multiplicities, accidental degeneracy, localization, and dependence on the values ...
Computational simulation of type-II superconductivity including pinning phenomena
(American Physical Society, 1995-06-15)
A flexible tool, based on the finite-element method, for the computational simulation of vortex phenomena in type-II superconductors has been developed. These simulations use refined or newly developed phenomenological ...
Scanning near-field optical microscopy utilizing silicon nitride probe photoluminescence
(AIP Publishing, 2005-11)
We describe a simple method for performing high-resolution scanning near-field optical microscopy (SNOM). A commercial Si3N4 tip is illuminated by an intense light source, which causes the tip to emit redshifted (inelastically ...
Numerical Approximations of the Dynamical System Generated by Burgers' Equation with Neumann-Dirichlet Boundary Conditions
(EDP Sciences, 2013-09)
Using Burgers' equation with mixed Neumann-Dirichlet boundary conditions, we highlight a problem that can arise in the numerical approximation of nonlinear dynamical systems on computers with a finite precision floating ...
Small-energy analysis for the self-adjoint matrix Schrodinger operator on the half line
(AIP Publishing, 2011-10)
The matrix Schrodinger equation with a self-adjoint matrix potential is considered on the half line with the most general self-adjoint boundary condition at the origin. When the matrix potential is integrable and has a ...
