Anisotropic Hardy Spaces of Musielak-Orlicz Type with Applications to Boundedness of Sublinear Operators

open access: yesThe Scientific World Journal, 2014
Let φ:ℝn×[0,∞)→[0,∞) be a Musielak-Orlicz function and A an expansive dilation. In this paper, the authors introduce the anisotropic Hardy space of Musielak-Orlicz type, HAφ(ℝn), via the grand maximal function.

Geostatistical analysis of disease data: accounting for spatial support and population density in the isopleth mapping of cancer mortality risk using area-to-point Poisson kriging

open access: yesInternational Journal of Health Geographics, 2006
Background Geostatistical techniques that account for spatially varying population sizes and spatial patterns in the filtering of choropleth maps of cancer mortality were recently developed.

More about metric spaces on which continuous functions are uniformly continuous

open access: yesBulletin of the Australian Mathematical Society, 1986
An Atsuji space is a metric space X such that each continuous function form X to an arbitrary metric space Y is uniformly continuous. We here present (i) characterizations of metric spaces with Atsuji completions; (ii) Cantor-type theorems for Atsuji ...

Validation of Sensing Ocean Surface Currents Using Multi-Frequency HF Radar Based on a Circular Receiving Array

open access: yesRemote Sensing, 2018
To reduce the floor space of receiving antenna arrays, the Radio Ocean Remote SEnsing (RORSE) laboratory of Wuhan University developed a circular receiving array for a multi-frequency high frequency (MHF) radar system in 2014, consisting of seven ...

Homomorphisms of the lattice of slowly oscillating functions on the half-line

open access: yesApplied General Topology
We study the space H(SO) of all homomorphisms of the vector lattice of all slowly oscillating functions on the half-line ℍ = [ 0 , ∞ ) . In contrast to the case of homomorphisms of uniformly continuous functions, it is shown that a homomorphism in H(SO ...

Non-uniformly continuous nearest point maps

open access: yesProceedings of the American Mathematical Society
We construct a Banach space satisfying that the nearest point map (also called proximity mapping or metric projection) onto any non-singleton compact and convex subset is continuous but not uniformly continuous. The space we construct is locally uniformly convex, which ensures the continuity of all these nearest point maps.

Equilibrium states for non-uniformly expanding maps: decay of correlations and strong stability [PDF]

open access: yes, 2012
We study the rate of decay of correlations for equilibrium states associated to a robust class of non-uniformly expanding maps where no Markov assumption is required.

On uniformly continuous Nemytskij operators generated by set-valued functions

open access: yes, 2010
Let I = [0, 1], let Y be a real normed linear space, C a convex cone in Y and Z a real Banach space. Denote by clb(Z) the set of all nonempty, convex, closed and bounded subsets of Z. If a superposition operator N generated by a set-valued function F : I

Dynamic recrystallization and microstructural evolution in 40CrNi2MoV steel during forging

open access: yesiScience
Summary: Reactor pressure vessel (RPV) studs require uniform microstructures for reliability. A strain-compensated Arrhenius constitutive model and dynamic recrystallization (DRX) model for 40CrNi2MoV steel were established via isothermal compression ...
