Toward a Multi-Layer Defence Framework for Securing Near-Real-Time Operations in Open RAN

IEEE Open Journal of the Communications Society
Securing the near-real-time (near-RT) control operations in Open Radio Access Networks (Open RAN) is increasingly critical, yet remains insufficiently addressed, as new runtime threats target the control loop while the system is operational.

Access Point Selection and Localization for Cluster‐Based Realization of a Device‐to‐Device Cell‐Free 6G Communications Network

IET Communications, Volume 19, Issue 1, January/December 2025.
We introduce a fully distributed framework that leverages belief‐desire‐intention extended (BDIx) agents on user devices to perform dynamic clustering and access‐point selection in a cell‐free 6G network, using both classical and deep‐learning methods for deterministic, scalable AP grouping.

Interoception, cardiac health, and heart failure: The potential for artificial intelligence (AI)—driven diagnosis and treatment

Physiological Reports, Volume 13, Issue 1, January 2025.
Artificial intelligence (AI) and the human brain: The brain governs interoception by perceiving internal bodily sensations. AI advancements present valuable opportunities to deepen our understanding of this intricate process. Abstract “I see, I forget, I read aloud, I remember, and when I do read purposefully by writing it, I do not forget it.” This ...

Survey on coherent multiband splicing techniques for wideband channel characterization

IET Communications, Volume 18, Issue 19, Page 1319-1334, December 2024.
Coherent multi‐band splicing offers an effective approach, extending existing band‐limited communication systems to support high‐precision sensing applications by combining multiple narrow‐band measurements. However, this method presents considerable challenges, particularly in compensating for phase offsets and hardware distortions before merging the ...
