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

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.

On Robust Optimal Joint Deployment and Assignment of RAN Intelligent Controllers in O-RANs

IEEE Open Journal of the Communications Society
The open radio access network (O-RAN) architecture is consolidating the concept of software-defined cellular networks beyond 5G networks, mainly through the introduction of the near-real-time radio access network (RAN) intelligent controller (Near-RT RIC)

N4-acetylcytidine in LncRNA Gm26917 Promotes Translation in Female Germline Stem Cells by Recruiting Ribosomal Protein mRNA via EEF1A1. [PDF]

Adv Sci (Weinh)
This work establishes that ac4C modification on lncRNA Gm26917 governs its spatial interactions with Rpl10 mRNA, and RBP EEF1A1 mediates the interaction between Gm26917 and Rpl10. It elucidates a novel ac4C‐Gm26917‐EEF1A1‐Rpl10 axis in FGSC maintenance both in vitro and in vivo, and provides a potential molecular target for modulating germ cell ...

Fasting and Caloric Restriction Activate an ADIOL-NHR-91-Kynurenine Pathway Signaling Axis to Promote Healthspan. [PDF]

Aging Cell
The steroid hormone ADIOL emerges as a key mediator of fasting–and caloric restriction–induced healthspan benefits in C. elegans. These regimens activate ADIOL production, which acts through the estrogen receptor β homolog NHR‐91 to reduce neural kynurenic acid levels and enhance healthspan independently of lifespan. ADIOL supplementation, even late in
