Evaluation of the neo-glottal closure based on the source description in esophageal voice [PDF]

open access: yes, 2008
The characteristics of esophageal voice render its study by traditional acoustic means to be limited and complicate. These limitations are even stronger when working with patients lacking minimal skills to control the required technique. Nevertheless the

Tuning D‐Band Center of Vanadium in Constructing Lattice‐Matched Coherent Heterostructure for Enhanced Sodium Storage

open access: yesAdvanced Functional Materials, EarlyView.
The coherent heterostructure and the strong stress field at the heterointerface upshift the d‐band center of vanadium toward the Fermi level, which effectively lowers the Na+ diffusion barrier, facilitates charge transfer and accelerates reaction kinetics.

BASSA: New software tool reveals hidden details in visualisation of low‐frequency animal sounds

open access: yesEcology and Evolution
The study of animal sounds in biology and ecology relies heavily upon time–frequency (TF) visualisation, most commonly using the short‐time Fourier transform (STFT) spectrogram.

Phase Engineering of a 1D van der Waals Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
Explores the transformative potential of 1D van der Waals materials, focusing on the monoclinic‐to‐tetragonal phase transition in NbTe4, its atomic‐scale mechanisms, and significant metal‐insulator transition (MIT) behavior. Highlights advanced imaging insights and the applications of reversible phase transitions in memory devices, sensors, and ...

Pitch in esophageal speech

open access: yesSouth African Journal of Communication Disorders, 1975
Most reports on pitch in esophageal speech emphasize that it is low-pitched with a measured fundamental frequency rarely higher than 100 cps. Our investigations show, however, that much esophageal 'phonation' lacks periodicity and, therefore, a ...

A cross-linguistic database of phonetic transcription systems [PDF]

open access: yes, 2018
Contrary to what non-practitioners might expect, the systems of phonetic notation used by linguists are highly idiosyncratic. Not only do various linguistic subfields disagree on the specific symbols they use to denote the speech sounds of languages, but

Bioinspired Shape Reconfigurable, Printable, and Conductive “E‐Skin” Patch with Robust Antibacterial Properties for Human Health Sensing

open access: yesAdvanced Functional Materials, EarlyView.
In this article, Hojin Kim, Sayan Deb Dutta, and co‐workers report a shape‐reconfigurable, 3D printable, and highly adhesive slime‐like ‘electronic skin’ or ‘E‐skin’ patch for human health sensing and tissue engineering applications. The dual reinforcement of hydrogel patch with carbon nanotubes (CNTs) and cellulose nanocrystals (CNCs) improve the ...

Objective dysphonia quantification in vocal fold paralysis: comparing nonlinear with classical measures [PDF]

open access: yes, 2009
Clinical acoustic voice recording analysis is usually performed using classical perturbation measures including jitter, shimmer and noise-to-harmonic ratios.

A comparison of the Mallampati test in supine and upright positions with and without phonation in predicting difficult laryngoscopy and intubation: A prospective study

open access: yesJournal of Anaesthesiology Clinical Pharmacology, 2015
Background and Aims: Difficult ventilation and intubation have been recognized as the forerunners of hypoxic brain damage during anesthesia. To overcome catastrophic events during anesthesia, an assessment of the airway before induction is of paramount ...
