Abstract Clinical observations show that patients with anorexia nervosa (AN) are surprisingly free from infectious diseases. There is evidence from studies in Drosophila melanogaster that starvation leads to an increased expression of antimicrobial p

Publikováno v: IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. 68:3423-3429

This article presents a study of special material properties of the single crystalline material Ca3TaGa3Si2O14 (CTGS = Catangasite). The comparatively highly ordered crystal structure and acceptable piezoelectric strength make it a candidate for micr

Objective Previous research has found increasing evidence for difficulties in emotion recognition ability (ERA) and social cognition in anorexia nervosa (AN), and recent models consider these factors to contribute to the development and maintenance o

Macroscopic Disk Rotation by Means of Surface Acoustic Waves

Autor: S. V. Biryukov, Andrei Sotnikov, Hagen Schmidt

Publikováno v: IEEE transactions on ultrasonics, ferroelectrics, and frequency control. 69(1)

It is shown experimentally that a flat piezoelectric disk poled perpendicular to its surface and suspended on a thin thread can be rotated about 50° by two surface acoustic waves (SAWs) intentionally excited with different amplitudes and propagating
