One developing theme in consciousness research is that consciousness is not the product of any specific component of the brain, rather it is an emergent property of the changing patterns of connectivity between different specialised functional components. For example, the dynamic core hypothesis proposes that conscious experience requires high levels of(More)

BACKGROUND Euvolemia is an important adequacy parameter in peritoneal dialysis (PD) patients. However, accurate tools to evaluate volume status in clinical practice and data on volume status in PD patients as compared to healthy population, and the associated factors, have not been available so far. METHODS We used a bio-impedance spectroscopy device, the(More)

Human blood Vγ9/Vδ2 T cells, monocytes and neutrophils share a responsiveness toward inflammatory chemokines and are rapidly recruited to sites of infection. Studying their interaction in vitro and relating these findings to in vivo observations in patients may therefore provide crucial insight into inflammatory events. Our present data demonstrate that(More)
OBJECTIVES Mobile phones (MP) are used extensively and yet little is known about the effects they may have on human physiology. There have been conflicting reports regarding the relation between MP use and the electroencephalogram (EEG). The present study suggests that this conflict may be due to methodological differences such as exposure durations, and(More)
A number of brain regions are associated with the subjective experience of pain. This study adds to our understanding of the neural mechanisms involved in pain by considering the relation between cortical oscillations in response to pain, with and without hypnosis and hypnotic analgesia, and the subjective experience of pain. Thirty-three subjects' neural(More)
A three-dimensional simulation code (ffx) designed to analyze ion thruster optics is described. It is an extension of an earlier code and includes special features like the ability to model a wide range of grid geometries, cusp details, and mis-aligned aperture pairs to name a few. However, the principle reason for advancing the code was in the study of ion(More)
Differential sputter yields are reported for Molybdenum, Tantalum, and Tungsten after exposure to Xenon, Krypton, and Argon ion bombardment at multiple angles of incidence (0-60°) and ion energies (150-1500 eV). Differential yields were measured by sweeping a Quartz Crystal Microbalance (QCM) in a semi-circular arc over a given target in the plane defined(More)
A differential sputter yield measurement technique is described, which consists of a quartz crystal monitor that is swept at constant radial distance from a small target region where a high current density xenon ion beam is aimed. This apparatus has been used to characterize the sputtering behavior of various forms of carbon including polycrystalline(More)
Experiments are described that use sub-scale ion thruster optics (gridlets) comprised of 6 to 37 aperture pairs. Test results are used to determine limitations of several different ion optics systems that are operated at high net accelerating voltages of interest to high specific impulse ion thruster systems. Experimental results are compared to numerical(More)
