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.

E2 Service Models in O-RAN: A Specification-Grounded Tutorial and Implementation Analysis

IEEE Access
The E2 interface and its associated E2 Service Models (E2SMs) are the primary mechanisms through which the Near-Real-Time RAN Intelligent Controller (Near-RT RIC) observes and controls Radio Access Network (RAN) behavior in O-RAN.

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.

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.
