H2CD: Semantic‐Enhanced Heterogeneous Hypergraph Network With Large Language Model for Cognitive Diagnosis

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Cognitive diagnosis aims to infer learners' knowledge states from their exercise responses, enabling personalised education at scale. Existing methods represent exercises solely by coarse‐grained knowledge component annotations, overlooking semantic content and step‐level cognitive processes.

LLM‐Powered Data Synthesis on Blockchain for Fusion Isomerism Learning in Heterogeneous Federated Systems

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Severe data starvation, architectural heterogeneity and Byzantine vulnerabilities fundamentally impede the deployment of robust multiclass classification models in decentralised edge environments. To address these intertwined challenges, we propose fusion isomerism learning (FusionIL), a secure and domain‐agnostic framework that ...

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

High Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

Awareness of Basic Mathematical Operation Rules as Predictor of Perceived Algebraic Reasoning Confidence Among Non-mathematics Majors

This study examined whether the level of awareness of basic mathematical operation rules predicts the perceived algebraic reasoning confidence of first-year non-mathematics major students at the Polytechnic College of the City of Meycauayan during the Academic Year 2025–2026.

Computational Chemistry‐Driven Advances in Eco‐Friendly Insulation Gas Research: Multi‐Dimensional Prediction, Synergistic Screening, Stability Evaluation and Molecular Design

High Voltage, EarlyView.
ABSTRACT Sulphur hexafluoride has become a priority substance for greenhouse gas mitigation in electric systems. An ideal substitute should simultaneously satisfy requirements for dielectric strength, boiling point, global warming potential and chemical stability; however, these metrics are deeply coupled and mutually constraining at the molecular ...

Lyapunov‐Function‐Based Stability Region Estimation in Transient Stability Assessment of Inverter‐Based Resources: A Review

High Voltage, EarlyView.
ABSTRACT Electric power systems are undergoing a fundamental transition from synchronous generator (SG)‐dominated systems to inverter‐based resource (IBR)‐dominated systems. Lyapunov‐ and energy‐function‐based direct methods provide an effective way to estimate the stability region, also known as the region of attraction (ROA), and have become a ...
