VO2 Oscillator Circuits Optimized for Ultrafast, 100 MHz‐Range Operation

open access: yesAdvanced Electronic Materials, Volume 12, Issue 1, 7 January 2026.
The present study demonstrates ultrasmall (≈30 nm) VO2 Mott memristor‐based oscillators which enter the >100 MHz frequency range via device scaling and optimization of the circuit layout for high frequency operation. Time‐resolved investigation of switching dynamics along with circuit‐level and physics‐based electrothermal simulations identify physical

Optoelectronic Neuromorphic System Based on Amorphous Indium–Gallium–Zinc–Oxide Thin‐Film Transistor for Spiking Neural Networks

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
An amorphous indium–gallium–zinc–oxide (IGZO)‐based optoelectronic neuromorphic system integrating light guides is introduced. The IGZO‐based optoelectronic synaptic transistor demonstrates high retention through a negative gate bias and emulates synaptic plasticity.

Modulation and amplification of radiative far field heat transfer: Towards a simple radiative thermal transistor

open access: yes, 2015
We show in this article that phase change materials (PCM) exhibiting a phase transition between a dielectric state and a metallic state are good candidates to perform modulation as well as amplification of radiative thermal flux.

Deriving Movement Categories in Rugby Sevens

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 1, January 2026.
ABSTRACT The primary aim of this study was to generate sport‐specific movement category velocity thresholds for elite rugby sevens male and female players. Match activity data were collected via Global Positioning Systems (GPS) (10 Hz) from 19 male and 11 female players during 88 competitive international fixtures during the 2022/2023 and 2023/2024 ...

Resting state functional connectivity in the default mode network and aerobic exercise in young adults [PDF]

open access: yes, 2017
Around the world Alzheimer’s Disease (AD) is on the rise. Previous studies have shown the default mode network (DMN) sees changes with AD progression as the disease erodes away cortical areas.

Exercise Duration Modulates Cortisol Release and Chronic Cortisol Exposure Jeopardises T Cell Effector Functions

open access: yesImmunology, Volume 177, Issue 1, Page 94-105, January 2026.
Cortisol has been linked to poor cancer prognosis but can also be released during exercise. This study shows that transient cortisol exposure, as seen with exercise, does not impair T cell effector functions. In contrast, chronic cortisol signalling suppresses T cell functionality and promotes cancer cell proliferation, highlighting the importance of ...
