Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Radio After Radio: Redefining radio art in the light of new media technology through expanded practice [PDF]
, 2015 I have been working in the field of radio art, and through creative practice have been considering how the convergence of new media technologies has redefined radio art, addressing the ways in which this has extended the boundaries of the art form.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Weak Communication in Radio Networks [PDF]
, 2002 Quite often algorithms designed for no-collision-detection radio networks use a hidden form of collision detection: it is assumed that a station can simultaneously send and listen. Then, if it cannot hear its own message, then apparently a collision has occurred. IEEE Standard 802.11 says that a station can either send or listen to a radio channel, but

Performance evaluation of OFDM and impulse-radio ultra-wideband over fiber distribution for in-building networks [PDF]
, 2009 This paper reports the compared performance of the two main ultra-wideband (UWB) implementations, OFDM-based (OFDM-UWB) and impulse-radio UWB, when transmitted over optical fiber for in-building communications employing external electro-optic modulation.

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
