A multi-DOF ultrasonic motor developed in our previous study has significant potentials for dexterous actuation. The ultrasonic motor provides multiDOF rotation of a spherical rotor using three natural vibrations of a bar-shaped stator. In this paper, numerical analyses on the multi-DOF ultrasonic motor are conducted. First, a forward model of multi-DOF ultrasonic motor is developed considering...

ompetent performance of an ultrasound examination of any type is reliant on an understanding of the basic physical principles that govern the production of ultrasound waves and their interaction with biological tissues of differing densities and consistencies. It is also necessary to understand the basic concepts of how the ultrasound systems work and the concepts underlying their manipulation ...

Introduction/aims Photochemical internalization (PCI) is a novel technology facilitates the delivery of macromolecules into cytoplasm. The initial mechanism and practical application was described by Berg et al. in 1999. This, first in human trial, is an open, phase I dose escalating study to evaluate the safety and tolerance of the photosensitizer (amphinex) that is used to initiate the photoc...

Through extracellular measurements of photoreceptor responses to flashed stimuli, we examined how the bleaching of rhodopsin affects increment receptor threshold in the isolated retina of the skate (Raja oscellata and R. erinacea). Both initially unbleached and previously bleached photoreceptors, when exposed to full-field luminous backgrounds of fixed intensity, attain approximately stable lev...
