Low‐temperature dissociation of zircon in highly alkaline conditions: A cautionary note for studies on natural glasses of debated origin

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 7, Page 1573-1586, July 2025.
Abstract Dissociated zircon is largely used as a robust indicator of glasses generated by impact cratering and airbursts. The reaction of zircon dissociation, i.e. ‘ZrSiO4 → ZrO2 + SiO2’, requires high temperatures (>1670°C) only reached by extreme geological processes. Using high‐temperature experiments, this study shows that zircon can dissociate and

Performance and reliability evaluation of an improved machine learning‐based pure‐tone audiometry with automated masking

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 11, Issue 2, Page 173-188, June 2025.
Abstract Objective Automated air‐conduction pure‐tone audiograms through Bayesian estimation and machine learning (ML) classification have recently been proposed in the literature. Although such ML‐based audiometry approaches represent a significant addition to the field, they remain unsuited for daily clinical settings, in particular for listeners ...
