MAC Protocol Design for Optical Wireless Body‐Area Networks: Latency, Energy Efficiency and Scalability Analysis

IET Networks, Volume 15, Issue 1, January/December 2026.
This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

TRust Your GENerator (TRYGEN): Enhancing Out-of-Model Scope Detection

AI
Recent research has drawn attention to the ambiguity surrounding the definition and learnability of Out-of-Distribution recognition. Although the original problem remains unsolved, the term “Out-of-Model Scope” detection offers a clearer perspective. The

Joint Time Synchronisation and Localisation Method by TDOA Observation in 5G Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work proposes a method for joint time synchronisation and localisation problems and proposes to obtain the initial values of the alternating iteration algorithm through solving the MVIE problem. The simulations showcase the satisfying positioning accuracy and clock synchronisation accuracy of the proposed method.

Blocking Interference Mechanism in Networked Radios Under UWB HPM

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This paper conducts a systematic cross‐level analysis of the damage mechanism encompassing ‘electromagnetic interference–hardware impairment–communication performance’ for QPSK‐based networked radios. Using ultra‐wide spectrum pulse signals as the interference source, the study considers the scenario where electromagnetic interference causes damage to ...

A Koch Fractal Octagonal Antenna with a Compact Design and Defected Ground Structure (DGS) for Ultra-Wideband (UWB) Wireless Usage.

Jordanian Journal of Computers and Information Technology
This paper introduces a Koch fractal octagonal antenna designed for the Ultrawideband (UWB) Frequency range. The utilization of the Koch fractal in the antenna design contributes to size reduction as well as provides compactness in the antenna for UWB ...

Obstacle‐Aware Navigation for MAVs Using Constant Flow Divergence Control and Texton‐Based Visual Cues

Journal of Robotics, Volume 2026, Issue 1, 2026.
Tiny flying insects rely heavily on optical flow for landings and navigation. By maintaining a constant optical flow divergence, they can approach targets or obstacles with an exponential decay of both relative distance and velocity. Previous studies have shown that Micro Air Vehicles (MAVs) leverage this control strategy for efficient landings and ...

The zinc finger domains of PARP‐1 are selectively and potently inhibited by the Au(I)‐based drugs sodium aurothiomalate and aurothioglucose

FEBS Letters, Volume 599, Issue 24, Page 3618-3628, December 2025.
PARP‐1 is a key enzyme in the DNA damage response, and its inhibition induces cancer cell death via synthetic lethality. Au(I)‐based drugs, such as aurothioglucose and sodium aurothiomalate, block PARP‐1's DNA‐dependent activity by targeting its zinc finger domains.
