Energy evolution of T-odd gluon TMDs at small $x$ [PDF]

open access: yes, 2022
We study the energy or TMD evolution of the three leading twist dipole type T-odd gluon TMDs inside a transversely polarized nucleon, all of which at small $x$ dynamically originate from the spin dependent odderon.

Analysis of Energy Evolution Characteristics of Salt Rock Under Different Loading Rates

open access: yesFrontiers in Earth Science, 2022
The existing uniaxial compression test results of salt rock under different loading rates are used to study its energy evolution characteristics during deformation and failure in this study. First of all, the influence of loading rate on the total energy

The Classification and Evolution of Bacterial Cross-Feeding [PDF]

open access: yes, 2019
Bacterial feeding has evolved toward specific evolutionary niches and the sources of energy differ between species and strains. Although bacteria fundamentally compete for nutrients, the excreted products from one strain may be the preferred energy ...

Mechanical characteristics and energy evolution law of sandstone failure process under post-peak cold and heat cycle

open access: yesMeikuang Anquan, 2023
In coal fire control, grouting/water extinguishing is often repeated for reasons such as re-ignition. The surrounding rock undergoes repeated heating and water cooling, resulting in strength reduction and damage, and collapse and cracks on the extended ...

Microstructure Evolution in a Solid Oxide Fuel Cell Stack Quantified with Interfacial Free Energy [PDF]

open access: yes, 2021
Degradation of electrode microstructure is one of the key factors affecting long term performance of Solid Oxide Fuel Cell systems. Evolution of a multiphase system can be described quantitatively by the change in its interfacial energy.

Uniaxial compression failure and energy dissipation of marble specimens with flaws at the end surface

open access: yes工程科学学报, 2020
It is a fact that a large number of defects such as cracks, voids, inclusions, weak planes, and joint sets are generated within the rock mass during the process of rock formation because of geological-tectonic evolution.

An investigation on the effect of high energy storage anchor on surrounding rock conditions [PDF]

open access: yesRoyal Society Open Science, 2020
High pre-tension bolt is an effective strata control technique and is the key to ensure the stability of anchorage and roadway. Based on the performances of high energy storage tension rock bolts in different rock properties, this study proposed a ...
