There are no objective differences in neural elements that explain regional differences in neural influences along the smooth muscle (SM) esophageal body (EB). Regional differences in muscle properties are present in the lower esophageal sphincter (LES). This study examines whether regional differences in SM properties exist along the EB and are reflected in length-tension relationships and res...

This thesis presents a fuzzy logic controller aimed at maintaining constant tension between two adjacent stands in tandem rolling mills . The fuzzy tension controller monitors tension variation by resorting to electric current comparison of different operation modes and sets the reference for speed controller of the upstream stand. Based on modeling the rolling stand as a single input single ou...

YAKOV RAPOPORT, The doctors'plot, transl. Natina Perova and Raissa Bobrova, London, Fourth Estate, 1991, pp. xii, 280, illus., £17.95 (1-872180-13-2). On 13 January 1953, the astounded citizens of the USSR heard a massive "criminal conspiracy" denounced. Prominent Soviet physicians had conspired to kill the leaders of the country by medical means. A round of arrests followed involving high-rank...

Writers of statistics textbooks tend to copy other textooks rather than draw on experience. This leaves a serious ap: Techniques that are highly useful in practice are not aught. With this series of columns I am trying to fill that ap. The first column [1] pointed out that doing something imperfect) is better than doing nothing. The second [2] was bout the value of transforming your data. A thi...

We introduce a new visualization method for temporal data, Spiral Theme Plot, by combining ThemeRiver method, spiral patterns, and scatter plot technique. Similar to ThemeRiver, data in different categories (themes) are visualized in different bands, but also in a spiral pattern. Themes are stacked along a spiral curve, which represent the time axis. Individual data points are plotted within th...

Computer-assisted interactive visualization has become a valuable tool for discovering the underlying meaning of tabular data, including categorical tabular data. The capabilities of the more traditionally mundane kinds of pictures like scatter plots can be expanded to usefully depict categorical tabular data by incorporating annotations and transforms, and by integrating the extensions into an...

The effects on myocardial oxygen consumption and mechanics of acute, simulated aortic and mitral regurgitation were studied in open-chest, anesthetized dogs to determine how changes in the mechanical performance of the ventricle alter oxygen consumption. When regurgitation was induced acutely with effective stroke volume (total stroke volume less regurgitant volume) and heart rate held constant...
