Toward an idiographic understanding of the role of sleep‐mood dynamics in adolescents' internalizing symptoms

JCPP Advances, EarlyView.
Abstract Background Adolescence is marked by increased vulnerability to sleep disturbances and mood disorders. Understanding how day‐to‐day changes in sleep and mood are linked within the same individual is crucial for clarifying sleep's role in emerging internalizing disorders. However, the extent to which an adolescent's fluctuations in sleep predict

Study on accumulation deformation characteristics of silty clay based on dynamic triaxial tests

Scientific Reports
Silty clay is a common compressible soil found in many engineering projects, where its deformation behavior is particularly complex under cyclic loading. This study uses the GDS dynamic triaxial testing system to examine how silty clay deforms under different moisture contents, confining pressures, and cyclic stress ratios (CSR).

Numerical Investigation of the Influence of Interparticle Cohesion During the Shear Behavior of Granular Soil

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Interparticle cohesive forces play a crucial role in governing the shear behavior of many soils; however, quantifying this effect remains challenging due to limited microscopic insights available from laboratory experiments. In this context, the current study aims to investigate the influence of microscale cohesion on the shear response using ...

Shapes of Gas, Gravitational Potential and Dark Matter in Lambda-CDM Clusters

, 2011
We present analysis of the three-dimensional shape of intracluster gas in clusters formed in cosmological simulations of the Lambda-CDM cosmology and compare it to the shape of dark matter distribution and the shape of the overall isopotential surfaces ...

Dynamic triaxial test research on the effect of water content on the dynamic characteristics of rubber-sand particles

British Journal of Multidisciplinary and Advanced Studies, 2023
In order to understand the effect of moisture content on the dynamic characteristics of rubber-sand particles (Rubber-Soil Mixture, RSM), a dynamic triaxial test was carried out. Before the test, the rubber particles and sand were mixed according to the rubber volume ratio of 0%, 25%, 30%, 40%, 50%, 75%, and 100%, and the water content was 0%, 5%, and ...

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.
