A quartz Bulk Acoustic Wave resonator is designed to coherently trap phonons in such a way that they are well confined and immune to suspension losses so they exhibit extremely high acoustic Q-factors at low temperature, with Q × f products of ...

Exploring longitudinal relationships among Alzheimer's disease biomarkers
Abstract INTRODUCTION While most studies of Alzheimer's disease (AD) examine cross‐sectional relationships among biomarkers, longitudinal relationships are also highly relevant. METHODS This study in the Alzheimer's Disease Neuroimaging Initiative cohort (n = 373) used non‐parametric Spearman correlations to explore the relationships of baseline values

A randomized phase 1b/2 trial of ABBV‐916 in adults with early Alzheimer's disease
Abstract INTRODUCTION ABBV‐916, an anti‐amyloid immunotherapy, was evaluated in patients with early Alzheimer's disease (AD). METHODS This phase 1b/2, double‐blind, placebo‐controlled study consisted of two stages: multiple ascending dose (Stage A) and dose expansion (Stage B).

A Novel Slit Lamp‐Based System for 3D Ultrasound of the Eye
Objectives This study aims to develop and evaluate a novel slit‐lamp‐based system to acquire 3‐dimensional (3D) ultrasound volumes using conventional ultrasound probes. Methods A slit‐lamp adapter was 3D printed and connected with a linear actuator and graphical user interface (GUI) system to control movement and create volumes of 2‐dimensional scans ...

This study compares two minimally invasive techniques, arthroscopic‐assisted uniportal spinal surgery (AUSS) and unilateral biportal endoscopy (UBE), for treating lumbar spinal stenosis using unilateral laminotomy with bilateral decompression (ULBD). Over a 2‐year follow‐up, perioperative outcomes, patient‐reported improvement, and radiological changes,

Cylindrical resonator filled with four alternating sectors of DPS and DNG materials [PDF]
A circular cylindrical metallic resonator with four alternating sectors of DPS and DNG materials is analyzed, in the frequency domain. The two materials are linear, lossless, homogeneous, and anti-isorefractive to each other.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
