Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration
Advanced Materials, EarlyView.A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

Slat Noise Prediction using Discontinuous Galerkin Method and Stochastic Turbulent Sound Source
, 2010 A promising way to predict airframe noise is the numerical solution of the Acoustic Perturbation Equations (APE) with the help of the Discontinuous Galerkin Method (DGM) and the Fast Random Particle Mesh (FRPM) method.

Acoustic monitoring of engine fuel injection based on adaptive filtering techniques [PDF]
, 2010 Diesel engines injection process is essential for optimum operation to maintain the design power and torque requirements and to satisfy stricter emissions legislations. In general this process is highly dependent upon the injection pump and fuel injector

Advanced Materials, EarlyView.Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Perceptual Learning of Acoustic Noise by Individuals With Dyslexia [PDF]
Journal of Speech, Language, and Hearing Research, 2014 PurposeA phonological deficit is thought to affect most individuals with developmental dyslexia. The present study addresses whether the phonological deficit is caused by difficulties with perceptual learning of fine acoustic details.MethodA demanding test of nonverbal auditory memory, “noise learning,” was administered to both adults with dyslexia and

Examining tunnel current responses to acoustic excitation for STMs in gaseous environments
AIP Advances, 2018 Scanning tunneling microscopes are used to examine surfaces and surface properties with sub-nanometer precision. However, this high precision means these microscopes are extremely sensitive to vibration.

, 2023 Abstract We introduce the concept of acoustic white noise (AWN) and then we get colored noiseas random sequences generated by dynamic systems (DS) with AWN input. Although DS isvirtual, the noise it generates can mimic real noise. Determining a system that generates agiven noise from white noise is called identification.

Application of a Discontinuous Galerkin Method to Predict Airframe Noise
, 2009 Unstructured grids greatly ease the mesh generation process in the case of complex geometries. The Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization even on this type of grid.

Acoustic, psychophysical, and neuroimaging measurements of the effectiveness of active cancellation during auditory functional magnetic resonance imaging [PDF]
, 2009 Functional magnetic resonance imaging (fMRI) is one of the principal neuroimaging techniques for studying human audition, but it generates an intense background sound which hinders listening performance and confounds measures of the auditory response ...
