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. ...
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 ...
Microscopic study of the 2/5 fractional quantum Hall edge
(American Physical Society, 2011-12-09)
This paper reports on our study of the edge of the 2/5 fractional quantum Hall state, which is more complicated than the edge of the 1/3 state because of the presence of edge sectors corresponding to different partitions ...

Diagnostics of AGN-driven molecular outflows in ULIRGs from Herschel-PACS observations of OH at 119 μm
(IOP Publishing Ltd., 2013-10)
We report on our observations of the 79 and 119 mu m doublet transitions of OH for 24 local (z < 0.262) ULIRGs observed with Herschel-PACS as part of the Herschel ULIRG Survey (HERUS). Some OH 119 mu m profiles display a ...
A unifying model for Neoproterozoic–Palaeozoic exceptional fossil preservation through pyritization and carbonaceous compression
Soft-tissue fossils capture exquisite biological detail and provide our clearest views onto the rise of animals across the Ediacaran–Cambrian transition. The processes contributing to fossilization of soft tissues, however, ...
Semiclassical interpretation of the spin interference effect observed in square loop arrays of In0.53Ga0.47As/In0.52Al0.48As quantum wells
(American Physical Society, 2011-12)
We present a semiclassical interpretation of the time-reversal spin interference (SI) observed in the square loop arrays made of In0.53Ga0.47As quantum wells [T. Koga et al., Phys. Rev. B 74, 041302 (2006)]. The simulated ...
Phenomenology of aging in the Kardar-Parisi-Zhang equation
(American Physical Society, 2012-03-27)
We study aging during surface growth processes described by the one-dimensional Kardar-Parisi-Zhang equation. Starting from a flat initial state, the systems undergo simple aging in both correlators and linear responses, ...
