An AI assisted four layer teaching model for computational thinking cultivation evaluated in a 14 week classroom pilot

Computational thinking has become a foundational competency for 21st-century learners, yet effective and scalable approaches to its cultivation remain insufficient. This study addresses three persistent gaps in the literature: the lack of systematically integrated AI-assisted ped...

Interpretable machine learning for prediction and regulation of bio-oil production, quality, and nitrogen content

Bio-oil derived from biomass pyrolysis is a promising renewable liquid fuel, however, its utilization is limited by unstable production, low heating value, high acidity, and the presence of nitrogen-containing compounds. In this study, an interpretable machine learning framework...

1D/3D Perovskite Heterostructure via Anion Engineering of Ionic Liquids for High‐Performance Lateral Photodetectors

ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) have emerged as attractive photoactive materials for next‐generation photodetectors (PDs) due to their facile solution processability and excellent optoelectronic properties. However, the practical applications of perovskite‐b...

Socioeconomic determinants of HIV prevalence among women in Eswatini: A cross-sectional study

Eswatini records the world's highest HIV burden, with female HIV prevalence markedly elevated compared to males. Understanding the socioeconomic structural drivers of this epidemic is essential for evidence-based prevention policy. This cross-sectional longitudinal study used sec...
