A blaVIM-2 Plasmid Disseminating in Extensively Drug-Resistant Clinical Pseudomonas aeruginosa and Serratia marcescens Isolates [PDF]

open access: yes, 2014
Infections caused by carbapenem-resistant Enterobacteriaceae isolates are an issue of major global concern (1). Genes coding for metallo-β-lactamases (MβLs) identified in clinical isolates are associated with mobile elements and subject to horizontal ...

Key Processes of Silicon-On-Glass MEMS Fabrication Technology for Gyroscope Application

open access: yesSensors, 2018
MEMS fabrication that is based on the silicon-on-glass (SOG) process requires many steps, including patterning, anodic bonding, deep reactive ion etching (DRIE), and chemical mechanical polishing (CMP).

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities

open access: yesAdvanced Materials, Volume 38, Issue 13, 3 March 2026.
A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

Contactless Terahertz “Fiber Squeezer” for Tunable Dispersion Engineering in Unclad Silicon Dielectric Waveguides

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
Terahertz microscale silicon waveguides can be wholly unclad, making it possible to interact with guided waves contactlessly via evanescent fields. We exploit this with conductive walls that enforce a movable field‐null upon modal fields, enabling tunable dispersion and cutoff similar to a fiber squeezer, albeit without physical contact.

Lung Ischemia–Reperfusion Injury in Lung Transplant Surgery: Where Do We Stand?

open access: yesAntioxidants
Lung ischemia–reperfusion injury (LIRI) remains a major contributor to perioperative morbidity and mortality in thoracic surgery, especially for lung transplantations, where it is one of the principal drivers of primary graft dysfunction (PGD).
