Biinvariant functions on the group of transformations leaving a measure quasiinvariant [PDF]

open access: yes, 2014
Let $Gms$ be the group of transformations of a Lebesgue space leaving the measure quasiinvariant, let $Ams$ be its subgroup consisting of transformations preserving the measure.

The Alpha Magnetic Spectrometer (AMS): search for antimatter and dark matter on the International Space Station [PDF]

open access: yes, 1997
The AMS is a state of the art detector for extraterrestrial study of antimatter, matter and missing matter. After a precursor flight on STS91 in May 1998, AMS will be installed on the International Space Station where it will operate for three years.

Detecting Compaction Disequilibrium with Anisotropy of Magnetic Susceptibility [PDF]

open access: yes, 2006
In clay-rich sediment, microstructures and macrostructures influence how sediments deform when under stress. When lithology is fairly constant, anisotropy of magnetic susceptibility (AMS) can be a simple technique for measuring the relative consolidation

A Fast AM/AM and AM/PM Characterization Technique

open access: yes, 2003
In this paper a novel AM/AM and AM/PM power amplifier characterization technique is presented, exploiting signals interference properties. Key features of the proposed measurement technique are the simplicity, requiring basic scalar power measurements only, and the low cost of the utilized set-up; moreover, it allows a power amplifier distortion ...

Implementation research for the prevention of antimicrobial resistance and healthcare-associated infections; 2017 Geneva infection prevention and control (IPC)-think tank (part 1) [PDF]

open access: yes, 2019
Background Around 5–15% of all hospital patients worldwide suffer from healthcare-associated infections (HAIs), and years of excessive antimicrobial use in human and animal medicine have created emerging antimicrobial resistance (AMR).

Experimental Study on Anti-Explosion Performance of the Cavern Reinforced by Recoverable Deformation Energy Absorption Bolt

open access: yesApplied Sciences, 2023
To address the practical problem of decreased anchoring effect due to the detachment of the exterior bolt head from the cave wall under dynamic loads, this paper developed a partially recoverable displacement energy absorption (RDEA) bolt.

Is it possible to establish reference values for ankle muscle isokinetic strength? A meta-analytical study [PDF]

open access: yes, 2014
BACKGROUND: The importance of measuring ankle muscle strength (AMS) has been demonstrated in a variety of clinical areas. Much data has been accumulated using the Cybex Norm isokinetic dynamometer but a uniform framework does not exist.
