Extracellular Particles Derived From Mesenchymal Stromal Cells Reduce Pseudomonas aeruginosa Lung Infection and Inflammation in Mice

open access: yesJournal of Extracellular Biology, Volume 5, Issue 2, February 2026.
ABSTRACT The World Health Organization and the U.S. Centre for Disease Control and Prevention have reported that antibiotic‐resistant infections with Pseudomonas aeruginosa present a significant health risk worldwide. In the genetic disease Cystic Fibrosis (CF), chronic antibiotic‐resistant Pseudomonas lung infections and persistent inflammation remain

A widely tunable parametric amplifier based on a SQUID array resonator

open access: yes, 2007
We create a Josephson parametric amplifier from a transmission line resonator whose inner conductor is made from a series SQUID array. By changing the magnetic flux through the SQUID loops, we are able to adjust the circuit's resonance frequency and ...

HEMT 60 GHz amplifier

open access: yesElectronics Letters, 1985
A high electron mobility transistor (HEMT) amplifier has been fabricated which exhibits 7.5 dB gain at 61 GHz. This result was obtained with a quarter-micrometre gate-length depletion-mode HEMT. Reduction of source-gate resistance and gate length are primarily responsible for this performance.
