A measurement technique capable of recording three-dimensional laser induced images with a spatial resolution of 610x512x20 voxels over a volume of 29x24x15 mm(3) and at a frame rate of 1 kHz is presented. A novel approach for sweeping the illuminating laser sheet across the investigated volume is introduced as a key feature. The technique is applied to imaging nebulized water droplets with a nitrogen-jet central feature.

Importance: Noise exposure is a major modifiable risk factor for hearing loss, yet it is not known whether it affects the rate of hearing decline in aging.
Objective: To determine the association of noise exposure history with the rate of pure-tone threshold change per year.
Design, Setting, And Participants: This longitudinal cohort study was conducted in the ongoing community-based Medical University of South Carolina Longitudinal Cohort Study of Age-Related Hearing Loss (1988 to present with the sample based in Charleston, South Carolina, and surrounding area).

Background: The initiation of amyloid plaque deposition signifies a crucial stage in Alzheimer's disease (AD) progression, which often coincides with the disruption of neural circuits and cognitive decline. While the role of excitatory-inhibitory balance is increasingly recognized in AD pathophysiology, targeted therapies to modulate this balance remain underexplored. This study investigates the effect of perampanel, a selective non-competitive AMPA receptor antagonist, in modulating neurophysiological changes in hAPP-J20 transgenic Alzheimer's mice.

Electrical cardioversion presents one of the treatment options for atrial fibrillation (AF). However, the early recurrence rate is high, reaching ~40% three months after the procedure. Features based on vectorcardiographic signals were explored to find association with early recurrence of AF.

Perfluorooctanesulfonic acid (PFOS) is one of the most investigated Per- and polyfluoroalkyl substances (PFAS) for being the strongest compound to eliminate and having adverse health concerns. In this work, we have conducted the sonochemical treatment of PFOS simulated water under high (500 kHz) and low (22 kHz) frequencies while monitoring the operational parameters via an integrated sonochemical system. The integrated advanced sonochemical system includes software to monitor treatment power, solution temperature and frequency while allowing distinctive control of the reaction conditions.

We demonstrate high-resolution single-pixel imaging (SPI) in the visible and near-infrared wavelength ranges using an SPI framework that incorporates a novel, dedicated sampling scheme and a reconstruction algorithm optimized for the rapid imaging of highly sparse scenes at the native digital micromirror device (DMD) resolution of 1024 × 768. The reconstruction algorithm consists of two stages. In the first stage, the vector of SPI measurements is multiplied by the generalized inverse of the measurement matrix.
