Experimental inversion of the convective heat transfer coefficient of a vertical chord grid wire under transverse airflow

Wet chord grids have potential for dust removal, cooling, and condensation dehumidification of hot, humid mine return air, but their coupled models require a dry-wire gas-side baseline. This study applies a four-terminal electrothermal inversion protocol—constant-current Joule he...

Multi-objective optimization method for hybrid isolation systems using explicit seismic response prediction

In highly seismic regions, a hybrid isolation system integrating isolators and viscous dampers can achieve both isolation efficiency and displacement control. However, the quantitative design of damper parameters lacks theoretical guidance. To address this bottleneck, this study...

Latent profiles of instrumental and relational generative AI engagement among university students

This study examines how university students engage with generative AI (GenAI) across instrumental and relational domains using two independent, domain-specific exploratory surveys of Chinese university students (Study 1: N = 517; Study 2: N = 508). Study 1 assessed instrumental i...
