Two weight extrapolation via the maximal operator
(Elsevier, 2000-06-20)
We give several extrapolation theorems for pairs of weights of the form (w, Mkw) and (w, (Mw/w)r w), where w is any non-negative function, r>1, and Mk is the kth iterate of the Hardy–Littlewood maximal operator. As an ...

A digital index theorem
(World Scientific Publishing, 2001-11)
This paper is devoted to prove a Digital Index Theorem for digital (n − 1)-manifolds in a digital space (Rn, f), where f belongs to a large family of lighting functions on the standard cubical decomposition Rn of the ...

Structural elucidation of Β-(Y,Sc) 2Si 2O 7: Combined use of 89Y MAS NMR and powder diffraction
(International Union of Crystallography, 2011-08)
Although the structures of pure Sc2Si2O7 and Β-Y 2Si 2O 7 have been described in the literature using the C2/m space group, 29Si magic angle spinning (MAS) NMR measurements of the intermediate members of the Sc 2Si 2O 7-Β- ...

Wetting and interfacial order at nematic free surfaces
(IOP Publishing Ltd., 1996-07-20)
We apply a density-functional theory to the free surface of a model liquid crystal, to investigate the orientational order at the nematic free surface of systems exhibiting orientational wetting at the isotropic liquid-vapour ...

A novel orientation-dependent potential model for prolate mesogens
(American Institute of Physics, 2005)
An intermolecular potential is introduced for the study of molecular mesogenic fluids. The model combines distinct features of the well-known Gay-Berne and Kihara potentials by incorporating dispersive interactions dependent ...

Hysteresis in vibrated granular media
(Elsevier, 2000)
Some general dynamical properties of models for compaction of granular media based on master equations are analyzed. In particular, a one-dimensional lattice model with short-ranged dynamical constraints is considered. The ...

Expansion for the moments of a nonlinear stochastic model
(American Physical Society, 1996-10-14)
We present a procedure to systematically evaluate all the moments of the Fokker-Planck equation by expanding them in a power series in a given function of t. The expansion coefficients are easily determined in terms of ...

On the validity of linear hydrodynamics for low-density granular flows described by the Boltzmann equation
(European Physical Society, 1999)
The direct Monte Carlo simulation method is used to check the validity of the hydrodynamic description of a low-density granular flow in the linear region about the homogeneous cooling state. Good agreement is found between ...
