The large-scale properties of simulated cosmological magnetic fields [PDF]
, 2015 We perform uniformly sampled large-scale cosmological simulations including magnetic fields with the moving mesh code AREPO. We run two sets of MHD simulations: one including adiabatic gas physics only; the other featuring the fiducial feedback model of ...

Scaling and scale breaking in polyelectrolytes
The Journal of Chemical Physics, 1996 We consider the thermodynamics of a uniformly charged polyelectrolyte with harmonic bonds. For such a system there is at high temperatures an approximate scaling of global properties like the end-to-end distance and the interaction energy with the chain length divided by the temperature.

Scale invariance without scale selection [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 In this work we construct scale invariant descriptors (SIDs) without requiring the estimation of image scale; we thereby avoid scale selection which is often unreliable. Our starting point is a combination of log-polar sampling and spatially-varying smoothing that converts image scalings and rotations into translations.

Scale Dependent Dimensionality [PDF]
, 2000 We argue that dimensionality is not absolute, but that it depends on the scale of resolution, from the Planck to the macro scale.Comment: 3 pages ...

Connecting entropy scaling and density scaling
The Journal of Chemical Physics, 2022 It is shown that the residual entropy (entropy minus that of the ideal gas at the same temperature and density) is mostly synonymous with the independent variable of density scaling, identifying a direct link between these two approaches. The residual entropy and the effective hardness of interaction (itself a derivative at constant residual entropy ...

Matrix-Partitioned DDM for the Accurate Analysis of Challenging Scattering Problems
IEEE Access, 2020 A matrix-partitioned domain decomposition method based on integral equation using the out-of-core iterative solver is presented for accurately analyzing challenging electromagnetic scattering problems with limited memory.

Effect of cohesion on local compaction and granulation of sheared soft granular materials
EPJ Web of Conferences, 2017 This paper results from an ongoing investigation of the effect of cohesion on the compaction of sheared soft wet granular materials. We compare dry non-cohesive and wet moderately-to-strongly cohesive soft almost frictionless granular materials and ...

Large-scale effects on meso-scale modeling for scalar transport [PDF]
, 2005 The transport of scalar quantities passively advected by velocity fields with a small-scale component can be modeled at meso-scale level by means of an effective drift and an effective diffusivity, which can be determined by means of multiple-scale ...
