STUDY ON THE DRIVING MODEL OF ULTRASONIC MOTOR

open access: yesElectrica, 2005
The interface contact model between the stator and the rotor of traveling wave ultrasonic motor is presented, assuming that the rigid stator contacts the flexible rotor over an area, and the frictional material is regarded as distributed linear spring ...

Design of a linear-rotary ultrasonic motor for optical focusing inspired by the bionic motion principles of the earthworms

open access: yesInternational Journal of Smart and Nano Materials, 2022
Multi-motor configuration of multi-DOF (degree of freedom) optical system is a major source of redundant structure, putting a limitation on the simple and miniaturized design. Thus, a novel two-DOF ultrasonic motor (USM) is proposed to provide a feasible

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Ultrasonically Assisted Hammer-Action Penetrators in Planetary Regolith [PDF]

open access: yes, 2018
This paper describes the effects of combining ultrasonic vibration with hammer-action style penetrators, such as the HP3 probe on the InSight mission. By synchronizing short pulses of vibration with the impact of the hammer, the number of hammer strikes ...
