Phantom system for endotracheal tube cuff seal testing during mechanical ventilation

Leakage of orogastric secretions past endotracheal tube (ETT) cuffs contributes to ventilator-associated pneumonia (VAP), yet in vivo tracheal seal testing is impractical, requiring phantom evaluation. As the rigid cylinder specified in EN ISO 5361:2023 does not adequately repres...

Correlative high-speed synchrotron X-ray and inline coherent imaging of high-power laser welding

Abstract High-power laser welding is central to electric vehicle (EV) manufacturing, yet keyhole instability and associated defects remain difficult to control due to highly transient process dynamics. Here, we combine inline coherent imaging (ICI) and high-speed synchrotron X-ra...

Indistinguishable single photons from a quantum dot in a nanopost cavity

Wavelength-tunable sources of single photons are key devices for scaling up optical quantum technologies. In this context, individual quantum dots (QDs) embedded in broadband photonic nanostructures are particularly appealing. The nanopost cavity, which is built with a segment of...

Orientation-tunable correlated Chern insulating states in chiral twisted double bilayer graphene proximitized by WSe2

Moiré flat bands in graphene systems proximitized by transition-metal dichalcogenides (TMDCs) provide a setting where spin-orbit coupling (SOC) can reshape band topology. The crystallographic alignment angle Φ between TMDC and graphene layers is predicted to tune the balance of I...
