This study presents characteristics of hemorheology for six patients during long-term support (85-144 days) on a Novacor left ventricular assist device (LVAD) as a bridge-to-cardiac transplantation. Results indicate that a certain "baseline" rheology can be identified in patients whose support was uneventful. However, in the patients who had one or more(More)
Hemorrheology was studied in patients undergoing artificial heart support as a bridge-to-cardiac transplantation. Abnormal hemorrheology was seen in two patients, one on a Jarvik-7 total artificial heart, and the other on a Novacor left ventricular assist device. Both of these patients suffered neurologic episodes. The rheology of these two patients(More)
In recent years, educational technologists and designers have begun to explore a variety of ways in which physical and computational media can be integrated---for instance, through the design of "intelligent toys" for children. This paper describes our ongoing efforts at exploring a different sort of physical-computational integration, focusing on(More)
The erythrocyte rigidity of patients suffering from severe peripheral vascular disease (PVD) was measured by a filtration method using 3 microns pore size filters. Filtration pressures for both PVD patients and normal subjects showed a cell volume dependency, and patient filtration pressures were normalized to cell volume to evaluate intrinsic, ie,(More)
We develop a new off-shell formulation for six-dimensional conformal su-pergravity obtained by gauging the 6D N = (1, 0) superconformal algebra in superspace. This formulation is employed to construct two invariants for 6D N = (1, 0) conformal supergravity, which contain C 3 and C✷C terms at the component level. Using a conformal supercurrent analysis, we(More)
Blood rheologic properties were studied in 11 patients on Novacor LVAS support (1-126 days) as a bridge to transplantation. Overall, these patients showed slight increases in mean blood viscosity and red cell rigidity. Their mean plasma fibrinogen was in the upper normal range. However, the degree of rheologic change observed, and the individual factors(More)
We expand the generic model involving chiral matter, super Yang-Mills gauge fields, and supergravity to second order in the gravity and gauge prepotentials in a manifestly covariant and conformal way. Such a class of models includes conventional chiral matter coupled to supergravity via a conformal compensator. This is a first step toward calculating(More)
