In this study, the properties of controlled low strength material (CLSM) made from waste soil were examined, utilizing 53 different mix proportions, and a dataset was subsequently constructed. Models, such as particle swarm optimization (PSO)-support vector regression (SVR), genetic algorithm (GA)-SVR, grid search (GS)-SVR, developed to predict both flowability unconfined compressive (UCS). To assess models' performance, comparisons between experimental predicted values, residual...

The VUMAT user material subroutine is written for CFRP panel, Hashin damage criterion introduced. elastic constitutive model macro modeling method chosen. process under different working conditions numerically simulated reliability verified one-stage light gas gun loading experiment at...
Introduction The intricate interplay between gut microbiota and hyperuricemia remains a subject of growing interest. However, existing studies only provided snapshots the microbiome at single time points, temporal dynamics alterations during progression barrier remain underexplored. Our investigation revealed compelling insights into dynamic changes in both intestinal function throughout course hyperuricemia. Methods mice (HY) were given intragastric administration adenine potassium oxalate....
To investigate the dynamic compressive behavior of zirconium filaments/aluminum/polytetrafluoroethylene (mass fraction Zr fiber/Al/PTFE 3%/23.5%/73.5%) active materials, traditional formula Al/PTFE materials (Al/PTFE mass 26.5%/73.5%) and Al/Zr/PTFE were prepared by cold pressing sintering process.
