PURPOSE To describe nursing education and practice in Vietnam, and strategies that support empowerment of nursing as a socially significant profession for that country. DESIGN The Jones-Meleis health empowerment model was used as a framework to examine barriers and identify strategies that support empowerment. METHODS Fieldwork, interviews, and(More)
Multiview three-dimensional (3D) displays can project the correct perspectives of a 3D image in many spatial directions simultaneously. They provide a 3D stereoscopic experience to many viewers at the same time with full motion parallax and do not require special glasses or eye tracking. None of the leading multiview 3D solutions is particularly well suited(More)
Dielectric high-contrast sub-wavelength grating (SWG) structures have received much attention in recent years, offering a new paradigm for the integration of optical systems. Their nanoscale resonant properties can result in a complex and unintuitive far-field behavior that, if carefully crafted, allows the full control of the optical phase front from a(More)
We observed nanosecond-duration absorption transients in several hydrogenated amorphous silicon waveguides using picosecond pump-probe measurements. We posit this effect is due to mid-gap defect absorption and describe implications for integrated nonlinear optics.
Innovations in chemometrics are required for studies of chemical systems which are governed by nonlinear responses to chemical parameters and/or interdependencies (coupling) among these parameters. Conventional and linear multivariate models have limited use for quantitative and qualitative investigations of such systems because they are based on the(More)
An automated method for finding and extracting water regions from Synthetic Aperture Radar (SAR) imagery is presented. Three automated water finders are implemented for experimentation with two sets of SAR imagery obtained from the areas of Elizabeth City and Asheboro, North Carolina. The input radar image is first segmented into four categories of terrain(More)
We demonstrated 1.5-μm-band optical switching using the Kerr effect in a-Si:H photonic crystal nanocavities. Switching with pulse energies down to 18 fJ using a degenerate pump-probe technique was observed in cavities with Q-factors up to 30,000.
