Endoscopic Management of a Hypopharyngeal‐Subglottic Fistula: Case Series and Literature Review

open access: yesThe Laryngoscope, EarlyView.
A rare complication of prolonged intubation or laryngeal radiation is destruction of the posterior cricoid cartilage with resultant hypopharyngeal‐subglottic fistula leading to aspiration and inability to consume a regular diet. We describe a step‐by‐step endoscopic approach to the closure of a hypopharyngeal‐subglottic fistula.

Generation of Two‐Cycle Light Bullets With 2.0 mJ Energy via Self‐Compression of 5‐µm Pulses in Zinc Sulfide

open access: yesLaser &Photonics Reviews, EarlyView.
Simultaneous temporal soliton self‐compression with simultaneous formation of a radial Townes profile is reported for millijoule pulses at 4.9 µm wavelength in ZnS. Pulses as short as 37 fs are generated in a 1‐kHz pulse train. The compression regime appears below the onset of filamentation, yielding two‐cycle pulses with 2.0 mJ energy which translates

High throughput characterization method of electrical and phonon properties by dielectric resonant spectroscopy

open access: yesMaterials Genome Engineering Advances, EarlyView.
In conventional theories, electron‐phonon relaxation time τe‐p ${\tau }_{e\mbox{-}p}$—the average interval between two consecutive electron‐phonon collisions—is assumed to be independent of electron density. In this study, we establish a new relationship of τe−p=C∗·T−1·n−1/3 ${\tau }_{e-p}={C}^{\ast }\mathit{\cdot }{T}^{-1}\mathit{\cdot }{n}^{-1/3 ...

A Systematic Review of Empirical Studies on Situation Awareness: Perspectives From the Interaction Among Humans, Machines, and the Task Environment

open access: yesPsyCh Journal, EarlyView.
ABSTRACT Situational awareness (SA) refers to “knowing what is going on” in a situation. As an essential concept originating in aviation literature approximately 40 years ago, SA has demonstrated significant potential and has since been extended across various fields, leading to a growing body of research.
