Gradual volatile memristor–based artificial neurons with high uniformity for neuromorphic computing

InfoScience, EarlyView.
Schematic of leaky integrate‐and‐fire artificial neurons for MNIST image classification. Abstract Artificial neurons are pivotal for neuromorphic hardware, but the development of compact and uniform devices remains challenging. Conventional volatile memristors suffer from abrupt switching, which hinders spatiotemporal consistency.

Validation of the TruBlue Light Laser for Laryngeal Somatosensory and Perturbation Testing

The Laryngoscope, EarlyView.
This study validates a blue light laser method for assessing laryngeal somatosensory function by measuring perceptual thresholds, reflexive responses, discrimination acuity, and vocal perturbations in healthy adults. Results demonstrate that the method provides precise, reliable stimulation and yields quantifiable sensory and acoustic responses ...
