Thermally Programmable Two‐Port Non‐Hermitian Acoustic Metastructure for Broadband and Direction‐Dependent Absorption

Advanced Science, EarlyView.
A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low‐resource settings: a prospective quality improvement study

BJS (British Journal of Surgery), EarlyView., 2020
Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...
