Article Synopsis
  • * This study investigates the articulatory and acoustic characteristics of Mandarin rhotics using ultrasound imaging from 18 Northern Chinese speakers, focusing on different syllable positions (prevocalic, syllabic, and postvocalic).
  • * Findings indicate that syllabic and postvocalic rhotics can use various tongue shapes without significant acoustic differences, while prevocalic rhotics primarily utilize bunched shapes and often exhibit frication noise, with distinct formant frequencies across positions.

Ultrasound imaging of the tongue is biased by the probe movements relative to the speaker's head. Two common remedies are restricting or algorithmically compensating for such movements, each with its own challenges. We describe these challenges in details and evaluate an open-source, adjustable probe stabilizer for ultrasound (ALPHUS), specifically designed to address these challenges by restricting uncorrectable probe movements while allowing for correctable ones (e.

Objectives: Analysis of the clinical utility of rapid whole-genome sequencing (rWGS) outside of the neonatal period is lacking. We describe the use of rWGS in PICU and cardiovascular ICU (CICU) patients across four institutions.

Design: Ambidirectional multisite cohort study.
