Adsorption and Photocatalytic Activity of Covalent Organic Frameworks for Environmental Remediation: A Review of Density Functional Theory Studies

The contamination of water resources by heavy metals, radionuclides, and organic pollutants demands efficient materials for water treatment. Covalent organic frameworks (COFs) are promising candidates owing to their tunable porosity and functionalizable frameworks. This review ex...

Calibrated Prediction of Students’ Next Responses in Digital Mathematics Learning: A Completion-Ordered and Cold-Start-Aware Framework

Digital mathematics platforms support probabilistic prediction of subsequent student responses, but temporal ordering, score comparability and calibration affect the validity of evaluation. We evaluated AdaptiveMath-AI on a deterministic cohort of 385,037 Eedi interactions from 2...

Analytical Solutions of the Fractional Derivative Chen–Lee–Liu Equation

This paper investigates a Schrödinger-type fractional-order nonlinear equation known as the Chen–Lee–Liu equation. The fractional properties of the model are described by means of the reduced M-fractional derivative. Using a traveling-wave ansatz and a change in variables, the or...

Machine Learning for Predicting Protective Behavioral Intention Following Serious-Game-Based Flood Risk Education

Climate change is increasing the frequency of hydrological extremes such as floods, requiring more effective approaches to build community preparedness alongside traditional flood risk management. This study develops and evaluates a serious-game-based flood risk education interve...
