Surface acoustic wave/silicon monolithic sensor/processor

A new technique for sputter deposition of piezoelectric zinc oxide (ZnO) is described. An argon-ion milling system was converted to sputter zinc oxide films in an oxygen atmosphere using a pure zinc oxide target. Piezoelectric films were grown on silicon dioxide and silicon dioxide overlayed with gold. The sputtered films were evaluated using surface acoustic wave measurements, X-ray diffraction, scanning electron microscopy, Auger electron spectroscopy, and resistivity measurements. The effect of the sputtering conditions on the film quality and the result of post-deposition annealing are discussed. The application of these films to the generation of surface acoustic waves is also discussed

Surface acoustic waves/silicon monolithic sensor processor

Progress is reported in the creation of a two dimensional Fourier transformer for optical images based on the zinc oxide on silicon technology. The sputtering of zinc oxide films using a micro etch system and the possibility of a spray-on technique based on zinc chloride dissolved in alcohol solution are discussed. Refinements to techniques for making platinum silicide Schottky barrier junctions essential for constructing the ultimate convolver structure are described

Competing and conflicting interests in the care of critically ill patients

Medical professionals are expected to prioritize patient interests, and most patients trust physicians to act in their best interest. However, a single patient is never a physician's sole concern. The competing interests of other patients, clinicians, family members, hospital administrators, regulators, insurers, and trainees are omnipresent. While prioritizing patient interests is always a struggle, it is especially challenging and important in the ICU setting where most patients lack the ability to advocate for themselves or seek alternative sources of care. This review explores factors that increase the risk, or the perception, that an ICU physician will reason, recommend, or act in a way that is not in their patient's best interest and discusses steps that could help minimize the impact of these factors on patient care
