S-wave scattering of strangeness -3 baryons

, 2012
We explore the interactions of two strangeness -3 baryons in multiple spin channels with lattice QCD. This system provides an ideal laboratory for exploring the interactions of multi-baryon systems with minimal dependence on light quark masses.

A coupled multi-scale method for predicting the viscoelastic behavior of resin-based 3D braided composites

Materials & Design, 2020
A new alternative multi-scale calculation procedure was presented to characterize the time-dependent viscoelastic behaviors of resin-based three dimensional (3D) braided composites. The present investigation was processed based on micro-scale fiber/resin,

Detection of Harmonic and Interharmonics Contents in Water Desalination Plants' Distribution System Based on Deep Learning Algorithms

Energy Science &Engineering, Volume 13, Issue 11, Page 5451-5464, November 2025.
Developed harmonics and interharmonics detection framework. ABSTRACT Water desalination plants are significant consumers of electric power, making them some of the largest energy users in power grids. Their electricity consumption presents an urgent challenge for efficient and sustainable operation, and they are among the most power‐quality‐threatening

Mechanical characterization of PVA hydrogels' rate-dependent response using multi-axial loading.

PLoS ONE, 2020
The time-dependent properties of rubber-like synthesized and biological materials are crucial for their applications. Currently, this behavior is mainly measured using axial tensile test, compression test, or indentation.

Load-depth sensing of isotropic, linear viscoelastic materials using rigid axisymmetric indenters [PDF]

, 2016
An indentation experiment involves five variables: indenter shape, material behavior of the substrate, contact size, applied load and indentation depth. Only three variable are known afterwards, namely, indenter shape, plus load and depth as function of ...
