Pontine Tegmental Cap Dysplasia Presenting With Global Developmental Delay and Vestibulocochlear Nerve Aplasia: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT PTCD should be considered in children with developmental delay and sensorineural hearing loss. MRI is crucial for identifying the characteristic dorsal “tegmental cap” and associated hindbrain anomalies. Vestibulocochlear nerve aplasia may explain severe hearing impairment in PTCD.

A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

International Journal of Circuit Theory and Applications, Volume 54, Issue 9, Page 4469-4481, September 2026.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei

Developmental Dynamics, Volume 255, Issue 9, Page 845-866, September 2026.
Three populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

The (Reverse) Colavita Effect in Emotion Recognition: Children and Adults Come to Different Conclusions When Categorising Incongruent Emotional Audio‐Visual Stimuli

Infant and Child Development, Volume 35, Issue 5, September/October 2026.
ABSTRACT Previous work has shown that different sensory channels are prioritised across the life course, with children preferentially responding to auditory information and adults to visual information. The aim of the current study was to investigate whether this effect extends to more socially meaningful stimuli, namely emotional stimuli.
