Composition Operators from the Hardy Space to the Zygmund-Type Space on the Upper Half-Plane

open access: yes, 2009
Here we introduce the 𝑛 th weighted space on the upper half-plane Π + = { 𝑧 ∈ ℂ ∶ I m 𝑧 > 0 } in the complex plane ℂ . For the case 𝑛 = 2 , we call it the Zygmund-type space, and denote it by 𝒵 ( Π + ) .

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Testing the core–periphery hypothesis: a standardised multi‐phylum assessment of genetic diversity of marine coastal species

open access: yesEcography, EarlyView.
The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

Boundedness for Parametrized Littlewood-Paley Operators with Rough Kernels on Weighted Weak Hardy Spaces

open access: yesAbstract and Applied Analysis, 2013
The authors prove that the parametrized area integral and function are bounded from the weighted weak Hardy space to the weighted weak Lebesgue space as satisfies a class of the integral Dini condition, respectively.

A Reversed‐Active Sites Strategy to Boost the Activity and Durability of Perovskite for Seawater Electrolysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The capacity difference for inhibiting Cl− corrosion of LOM and AEM based catalysts preliminarily proves the effectiveness of the reversed‐active sites strategy. By virtue of regulation of ion ratio, perovskite La0.3SrCo0.5Fe0.5Ox (La0.3) with higher participation of lattice oxygen in OER, rapid bulk oxygen diffusion, and excellent OH− adsorption ...

Silver‐Based Supportless Membrane Electrode Assemblies for Electrochemical CO2 Reduction

open access: yesElectrochemical Science Advances, EarlyView.
ABSTRACT Most commonly, electrochemical CO2 reduction is performed in a three‐compartment setup employing gas diffusion electrodes (GDEs) to decrease mass transport limitations of the gaseous reactant CO2 to the reaction interface. However recently, there has been a rising number of investigations on suitable membrane electrode assemblies (MEAs) to ...
