Few-Layer Graphene Heater Enabled High-Precision Phase-Change Photonic Devices

Abstract Photonic computing overcomes the power and interconnect bottlenecks of conventional electronics through its high bandwidth, low latency, and parallel processing capability, making it ideal for next-generation AI and data-intensive applications. However, current photonic...

Beaconing detection via timing-based flow metadata analysis: implications for SCADA/ICS

Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS) are critical to the continuity of modern industrial infrastructure. Cyberattacks targeting these systems can lead to serious consequences, including production losses, physical damage, and threa...

DualGLEAN: Dual Allocation for VLM-Guided Generalized Category Discovery in Remote Sensing Images

Generalized category discovery (GCD) aims to classify known categories while discovering novel ones in unlabeled data, yet existing methods lack mechanisms to correct boundary-ambiguous samples that receive noisy pseudo-labels, as they primarily rely on visual feature learning wi...

A Self‐Supervised Framework for Space Object Behaviour Characterisation

ABSTRACT Foundation Models, which leverage large neural networks pre‐trained on unlabelled data before fine‐tuning for specific tasks, are increasingly being applied to specialised domains. Recent examples include ClimaX for climate and Clay for satellite Earth observation, but a...
