Ionizing radiation is an important component of multimodal therapy for alveolar rhabdomyosarcoma (ARMS). We sought to evaluate the ability of IFN-beta to enhance the activity of ionizing radiation. Rh-30 and Rh-41 ARMS cells were treated with IFN-beta and ionizing radiation to assess synergistic effects in vitro and as orthotopic xenografts in CB17 severe combined immunodeficient mice. In addit...

We studied on the feasibility of focused ultrasound for tactile feeling display. Our experiments showed that focused ultrasound at 1 MHz and 5 MHz effected our somatic sensation both by its radiation pressure and by direct stimulation to the nerve structures. The radiation pressure force generated by our apparatus was 0.23 gf/cm per 1-watt power consumption and evoked tactile feeling stably, wh...

Coupling effects of Earth oblateness and direct solar radiation pressure on the motion of an artificial satellite are evaluated. Secular and periodic terms are retained up to order three and two respectively, where the coefficient 2 J of the second zonal harmonic of the geopotential is considered of first order. The solution revealed the existence of secular terms at order three that arises fro...

This report presents an account of the demand made by solar radiation pressure 6n the attitude-control system of an earth satellite whose external configuration is in the shape of a rectangular prism, the surfaces being assumed to be perfectly reflecting. Expressions determining the amount of angular impulse that must be supp~ed by an attitude-control system in the course of a year in order to ...

We present a theoretical study of an experiment designed to detect radiation-pressure shot noise in an optomechanical system. Our model consists of a coherently driven optical cavity mode that is coupled to a mechanical oscillator. We examine the cross-correlation between two quadratures of the output field from the cavity. We determine under which circumstances radiation-pressure shot noise ca...

In recent years, samples pressurized in diamond anvil cells are being irradiated with energetic ion beams to investigate the response of solids to simultaneous exposure to ions and high pressure. The effects are numerous, e.g. inducing phase transitions far from their usual stability regime or creating and stabilizing phases that are normally not stable at ambient conditions, depending on the i...

High energy and high brilliance make the Advanced Photon Source (APS) an ideal tool for high pressure studies. In this paper, we describe the diamond anvil cell (DAC) facility that is being developed for the APS by the GeoSoilEnviroCARS group of the Consortium for Advanced Radiation Sources (CARS). The DAC program aims at studying properties of materials across the entire pressure-temperature s...

Our prior work has shown that high quality (Q) factor whispering gallery modes (WGMs) in liquid microdroplets can potentially induce single-photon-level nonlinear effects through radiation pressure on the interface. However, little is known about the nonlinear effects of other processes involving scattering force and thermocapillarity. In this study, we establish a numerical framework that can ...

A technique is presented in this paper for the analysis of acoustic radiation of baffled planar sources. This method is based on the concept of the radiation matrix which is a representation of the sound field radiated by complex sources. Both sound power and far-field pressure can be estimated using this method. Numerical simulation and experimental investigation were carried out to verify the...
