A possible common physical principle that underlies animal vocalization: theoretical considerations with an unsteady airflow-structure interaction model

Journal of Biomechanical Science and Engineering, 2016
We previously described an analytical model regarding how human falsetto voice is produced upon interaction between the respiratory airflow and vocal fold motion.

Pre-pausal devoicing and glottalisation in varieties of the south-western Arabian peninsula [PDF]

, 2007
A wide range of modern Arabic dialects exhibit devoicing in pre-pausal (utterance-final) position. These include Cairene [20], Gulf Arabic, San’ani [8], [18], Manaxah [19], Central Highland Yemeni dialects [1], Rijal Alma‘ (Asiri p.c.), Central Sudanese (

Pioneering the Future: Principles, Advances, and Challenges in Organic Electrodes for Aqueous Ammonium‐Ion Batteries

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Leveraging the numerous advantages of ammonium‐ion (NH₄⁺)—including cost‐effectiveness, low corrosiveness, preferential orientation, and rapid diffusion kinetics—aqueous NH₄⁺ batteries (AAIBs) have gained significant attention. This review highlights and evaluates the progress of AAIBs utilizing organic electrode materials such as small molecules ...

Wavelike Motion of a Mechanical Vocal Fold Model at the Onset of Self-Excited Oscillation

Journal of Biomechanical Science and Engineering, 2006
The vocal folds in the larynx experience a self-excited oscillation with a wavelike motion during speech owing to interaction with respiratory airflow.

Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

Advanced Materials, EarlyView.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Effects on vocal fold collision and phonation threshold pressure of resonance tube phonation with tube end in water.

Journal of Speech, Language and Hearing Research, 2013
PURPOSE Resonance tube phonation in water (RTPW) or in air is a voice therapy method successfully used for treatment of several voice pathologies. Its effect on the voice has not been thoroughly studied. This investigation analyzes the effects of RTPW on
