Ultrasound attenuation dependence on air compression or expansion processes [PDF]

open access: yes, 2010
In this work variation of ultrasonic attenuation coefficient is analyzed in terms of air compression or expansion processes. In\ud closed spaces changing air volume, the ultrasound attenuation coefficient depends on thermodynamic processes which occur ...

Development Status and Future Prospects of Hydrogen Energy Technology: Production, Storage, and Cost Analysis

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen is an energy carrier, produced from renewable and nonrenewable resources. It can be stored in a variety of materials and transported to distant locations. This article reviews progress in hydrogen technology by looking at environmental and economic impact, cost analysis, and policy support at government level as way forward for bringing it to ...

A companion to the preclinical common data elements and case report forms for in vivo rodent neuroimaging: A report of the TASK3‐WG3 Neuroimaging Working Group of the ILAE/AES Joint Translational Task Force

open access: yesEpilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force established the TASK3 working groups to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

Entanglement transfer of a Rydberg W-state to a multi-mode photonic state

open access: yesPhysical Review Research
A robust quantum protocol has been developed that achieves highly efficient entanglement transfer from a three-atom Rydberg system, initially in a W-state (|rrg〉+|rgr〉+|grr〉)/sqrt[3], to an equivalent photonic W-state (|101〉+|110〉+|011〉)/sqrt[3].

Adiabatic limits of Seiberg-Witten equations on Seifert manifolds [PDF]

open access: yesarXiv, 1996
We present a simpler proof for the existence of adiabatic limits. Moreover, we added a new section where the adiabatic process is reversed and in some nondegenerate cases we deform the adiabatic limits to genuine irreducible solutions of the SW equations.

Circularly Polarized Luminescence Inversion in AIE‐Active Crystal Enabled by Solvent‐Induced Transition Dipole Moment Regulation

open access: yesAggregate, EarlyView.
Crystals of chiral AIEgens exhibit achiral solvent‐induced CPL sign inversion with good optical waveguide properties, while the same helical structure and molecular chirality are retained in the crystalline state. Nonbonding interactions between the cocrystallized solvent molecules and AIEgens affect the θμ,m (S1 → S0) of electric and magnetic ...

Characteristic Analysis of Adiabatic Spray Absorption Process in Aqueous Ammonia Solution

open access: yesZhileng xuebao, 2013
An absorber is a key device of absorption refrigeration system, and it directly affects the performance of refrigeration system. As an important absorption type, adiabatic spray absorption process disperses the absorption fluid into fine droplets by ...

Experimental and numerical analyses of the dynamic failure processes of symmetric Taylor impact specimens

open access: yesEPJ Web of Conferences, 2018
Failure processes encountered in the Taylor impact specimen are of two kinds, Mode II cracks initiating within adiabatic shear bands and tensile cracks. Because friction occurring with the single Taylor configuration influences the failure processes, it ...
