REVEAL AD ‐ Prevalence of Moderate and Severe Atopic Dermatitis in Ireland: A Cross‐ Sectional, Real World Study of a Secondary Care Population

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Atopic dermatitis (AD) is a common inflammatory skin disease. However, limited data exist on its prevalence and incidence in Irish secondary care. Objectives REVEAL AD had two distinct but related objectives: (1) Estimate prevalence of moderate‐to‐severe AD in patients aged 12 years and older presenting to secondary care clinics in ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...
