Cybersecurity Driven Quantum Digital Twin for Proactive Threat Reversal in Open RAN

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
This paper presents a novel cybersecurity‐driven quantum digital twin (CQDT) architecture for proactive defence in 6G Open RAN. By integrating quantum observables and reinforcement learning, the framework maintains high fidelity and suppresses entropy under adversarial CPTP noise. CQDT achieves real‐time adaptation with sub‐20 ms latency, meeting URLLC

Dynamic Resource Allocation for 5G and Beyond Networks Slicing Based on Meta‐Federated Deep Reinforcement Learning

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study introduces a meta‐federated deep reinforcement learning (Meta‐FedDRL) framework to address dynamic resource allocation (DRA) challenges in ultra‐dense and heterogeneous 5G and beyond network slicing. The proposed approach enables distributed learning while preserving data confidentiality and enhancing generalization.

Composition and conservation status of rays sold in Baja California Sur, Mexico

Conservation Science and Practice, Volume 7, Issue 12, December 2025.
An analysis of the species composition of ray species sold under a general label in La Paz, Baja California, Sur Mexico. DNA barcode sequencing of the CO1 gene was utilized to assess ray filets, and species identification was compared to IUCN Red List to understand the vulnerability status of ray species being sold.

Energy‐Aware Optimisation for Off‐Grid ORAN With RIS and Edge Computing

IET Networks, Volume 14, Issue 1, January/December 2025.
Energy‐conscious off‐grid ORAN builds on solar‐powered remote units, separate DU/CU functionality, RIS components and a means for core network connection. ABSTRACT This paper proposes a strategy for designing Open Radio Access Networks (ORAN) to maximise their energy efficiency using solar power, supplemented by Reconfigurable Intelligent Surfaces (RIS)

An Efficient and Robust Estimation of Spatio‐Temporally Distributed Parameters in Dynamic Models by an Ensemble Kalman Filter

Journal of Advances in Modeling Earth Systems, Volume 16, Issue 2, February 2024.
Abstract The accuracy of Earth system models is compromised by unknown and/or unresolved dynamics, making the quantification of systematic model errors essential. While a model parameter estimation, which allows parameters to change spatio‐temporally, shows promise in quantifying and mitigating systematic model errors, the estimation of the spatio ...

CONVERGE: A Multi-Agent Vision-Radio Architecture for xApps

2024 IEEE Globecom Workshops (GC Wkshps)
Telecommunications and computer vision have evolved independently. With the emergence of high-frequency wireless links operating mostly in line-of-sight, visual data can help predict the channel dynamics by detecting obstacles and help overcoming them through beamforming or handover techniques.
