Ultrasound-Guided Repair of the Anterior Talofibular Ligament With or Without Gould Augmentation Is Safe and Improves Clinical Outcomes for Chronic Lateral Ankle Instability: A Case Series of 49 Patients.

Objectives: We have previously shown that ultrasound-guided repair results in an accurate anchor placement and restores ankle joint stability using cadaveric models. The objective is to assess the safety and clinical outcomes of ultrasound-guided ATFL repair with or without augmentation.

Methods: Forty-nine patients with chronic lateral ankle instability underwent ultrasound-guided ATFL repair with or without augmentation.

Explosion Detection Using Smartphones: Ensemble Learning with the Smartphone High-Explosive Audio Recordings Dataset and the ESC-50 Dataset.

Explosion monitoring is performed by infrasound and seismoacoustic sensor networks that are distributed globally, regionally, and locally. However, these networks are unevenly and sparsely distributed, especially at the local scale, as maintaining and deploying networks is costly. With increasing interest in smaller-yield explosions, the need for more dense networks has increased.

Three-Dimensional Nanoscale Imaging of SiO2 Nanofiller in Styrene-Butadiene Rubber with High-Resolution and High-Sensitivity Ptychographic X-ray Computed Tomography.

SiO2 aggregates in styrene-butadiene rubber (SBR) were observed using ptychographic X-ray computed tomography (PXCT). The rubber composites were illuminated with X-rays focused by total reflection focusing mirrors, and the ptychographic diffraction patterns were collected using a CITIUS detector in the range of -75° to +75° angle of incidence. The projection images of the rubber composites were reconstructed with a two-dimensional resolution of 76 nm, and no significant structural changes were observed during the PXCT measurements.
