Deformation characteristics of saturated remolded loess under cyclic traffic loads

open access: yesYantu gongcheng xuebao, 2022
To study the deformation laws of saturated remolded loess under the rotation of principal stress axis, the cyclic triaxial tests and cyclic traffic load tests on the saturated remolded loess under drainage are carried out by using the hollow cylinder ...

The earth pressure of retaining wall with cohesive fill based on principal stress rotation

open access: yesShuiwen dizhi gongcheng dizhi, 2021
The soil behind a wall is in a stress state with self-weight stress and horizontal stress as the main stress for the Rankine retaining wall with horizontal fill. However, there is a certain wall-soil friction and bonding force in practice.

Effect of principal stress rotation on dynamic characteristics of a sandy seabed under a partially reflected standing wave

open access: yes, 2020
Principal stress rotation (PSR) is one of the main stress conditions for a soil element subject to cyclic waves. It is one of the main causes behind generation of excess pore water pressure and cumulative plastic strain in soil deposits when drainage ...

Stress state at faults: the influence of rock stiffness contrast, stress orientation, and ratio [PDF]

open access: yesSolid Earth
The contemporary crustal stress state is primarily driven by gravitational volume forces and plate tectonics. However, there are various smaller-scale sources such as geological structures and stiffness contrast that perturb stresses and deviate them ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
