A Lagrangian approach for the incompressible Navier-Stokes equations with variable density
Inhomogeneous Navier-Stokes equations critical regularity piecewise constant density Besov spaces Lagrangian coordinates
2011/9/6
Abstract: Here we investigate the Cauchy problem for the inhomogeneous Navier-Stokes equations in the whole $n$-dimensional space. Under some smallness assumption on the data, we show the existence of...
A Model for the Origin of High Density in Loop-top X-ray Sources
Model Origin Density Loop-top X-ray Sources
2011/10/8
Super-hot looptop sources, detected in some large solar flares, are compact sources of HXR emission with spectra matching thermal electron populations exceeding 30 megakelvins. High observed emission ...
Designing Nonlinear Turbo Codes with a Target Ones Density
Nonlinear Turbo Codes Target Ones Density Information Theory
2011/8/30
Abstract: Certain binary asymmetric channels, such as Z-channels in which one of the two crossover probabilities is zero, demand optimal ones densities different from 50%. Some broadcast channels, suc...
Halo based reconstruction of the cosmic mass density field
galaxies: haloes – groups: general– cosmology: dark matter – large-scale structure of Universe – methods: numerical
2011/9/28
We present the implementation of a halo based method for the reconstruction of the cosmic mass density field. The method employs the mass density distribution of dark matter haloes and its environment...
Relationship between electron density and effective densities of body tissues for stopping, scattering and nuclear interaction of proton and ion beams
electron density body tissues proton and ion beams

In treatment planning of charged-particle radiotherapy, patient heterogeneity is normally modeled as variable-density water to best reproduce the stopping power. This water-based model would cause sub...
Uniform existence of the integrated density of states on metric Cayley graphs

2011/7/27
Abstract: Given a finitely generated amenable group we consider ergodic random Schr\"odinger operators on a Cayley graph with random potentials and random boundary conditions. We show that the normali...
Homogenization of Steklov spectral problems with indefinite density function in perforated domains

2011/7/28
Abstract: Spectral asymptotics of linear periodic elliptic operators with indefinite (sign-changing) density function is investigated in perforated domains with the two-scale convergence method. The l...
Density Functional Resonance Theory of Unbound Electronic Systems
Density Functional Resonance Theory Electronic Systems
2011/9/14
Density Functional Resonance Theory (DFRT) is a complex-scaled version of ground-state Density Functional Theory (DFT) that allows one to calculate the resonance energies and lifetimes of metastable a...
Evaluation of Phonon-level Density of UO2 by Molecular Dynamics Simulation

2012/4/5
Molecular dynamics calculation of UO2 in a wide temperature range are presented and dis-cussed. The calculated lattice parameters, mean square displacements, and dynamic prop-erty of phonon-level dens...
A framework for developing new approximate electronic structure methods is presented, in which the correlation energy of a many-electron system in the ground state is computed as in the single-referen...

Probing Asthenospheric Density Temperature Elastic Moduli Below the Western United States
2014/4/9
Periodic ocean tides continually provide a cyclic load on Earth’s surface, the response to which can be exploited to provide new insights into Earth’s interior structure. We used geodetic observations...

The asymptotic behavior of the integrated density of states for a randomly perturbed lattice at the infimum of the spectrum is investigated. The leading term is determined when the decay of the single...
Coding for High-Density Recording on a 1-D Granular Magnetic Medium
High-Density Recording 1-D Granular Magnetic Medium
