Ephemeral Subgraph Generation: Real-Time Knowledge GraphConstruction for Cross-System Investigation

This paper proposes Ephemeral Subgraph Generation (ESG), a real-time, LLM-guided approach that constructs temporary, question-specific knowledge graphs across heterogeneous engineering systems to outperform static retrieval and fixed-hop baselines in cross-system investigations, while also documenting and resolving specific software defects identified during evaluation.

DINOv2 versus Supervised Visual Representations for Tooth-Level Multi- Label Diagnosis Classification on Panoramic Radiographs: A Frozen-Feature Sample-Efficiency Study

This study demonstrates that while frozen DINOv2-small does not significantly outperform supervised ImageNet-pretrained ResNet50 on fully annotated panoramic radiographs, it provides superior sample efficiency and performance for tooth-level multi-label diagnosis classification under constrained annotation budgets.

Quantum AIO-ChameleonGAN for Behaviour-Aware Quantum–Classical Intrusion Detection of Adaptive Cyber Threats

This study introduces Quantum AIO-ChameleonGAN, a hybrid quantum-classical intrusion detection framework that integrates Angle of Incidence Optimization for contextual behavioural modelling with an eight-qubit Variational Quantum Circuit, achieving 99.85% accuracy and a 33.3% reduction in false negatives on the CIC-UNSW-NB15 dataset while demonstrating representational benefits through state-vector simulation.

Unsupervised Satellite Image Change Detection Using Quantum-Inspired Mapping and Weighted Hybrid Neighborhood MRFs

This paper proposes an unsupervised satellite image change detection framework that reformulates a context-aware Markov Random Field with weighted 8-connected neighborhoods as a QUBO problem, achieving competitive performance on the OSCD benchmark while maintaining compatibility with future quantum annealing architectures.
