A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures

Role of Pediatric Otolaryngologist in Pediatric Tracheostomy Code Blue Cases: A New Safety Initiative

open access: yesThe Laryngoscope, EarlyView.
ABSTRACT Objective A “Code Blue” is a term to activate an alarm for the resuscitation team for a patient who has a cardiopulmonary arrest. The role of a pediatric otolaryngologist in a tracheostomy‐related code blue case is not clearly defined. We aim to describe the role of pediatric otolaryngologists in pediatric tracheostomy code blue (PTCB) cases ...

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

open access: yesLaser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Non‐Uniform Programmable Photonic Waveguide Meshes

open access: yesLaser &Photonics Reviews, EarlyView.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...
