or 0.5 mg/day for alternate two-week periods without a loading dose. Control data were obtained both before and after the four weeks of treatment. After 13 days treatment with digoxin, 0.5 mg/day, there was a significant decrease in total electromechanical systole corrected for heart rate (QS2i), pre-ejection period (PEP), pre-ejection period corrected for heart rate (PEP,) and PEP/left ventric...

In orthogonal frequency division multiplexing (OFDM) systems, a time-domain equalizer (TEQ) is used to reduce the intersymbol interference (ISI) by shortening the channel impulse response when the channel length is larger than cyclic prefix (CP) length. However, conventional channel shortening methods may have frequency notch problem which will causes significant system performance degradation....

It has recently been demonstrated that acid-induced esophageal mucosal injury leads to esophageal shortening, raising the possibility that reflux esophagitis per se may contribute to the development of hiatal hernia. The aim of the present study was to determine whether mast cell-derived mediators are involved in this acid-induced esophageal shortening. Changes in esophageal length were continu...

A contraction abnormality of the left ventricle has previously been described in patients with systolic click-late systolic murmur syndrome. To determine if the contraction abnormality is present in the preprolapse period, LV dimensions and the instantaneous velocity of circumferential fiber shortening (VCF) were studied in 18 patients with the mitral valve prolapse and 16 normal subjects using...

In this paper we present an experiment to determine the types of constituents that influence polysyllabic shortening. Materials were designed to encourage the use of rhythmic, prominencebased, cross-word (Abercrombian) feet. Our preliminary results suggest that when polysyllabic shortening occurs, it operates preferentially within word-based constituents of the prosodic hierarchy (Selkirk [9], ...

This study is intended to describe and analyze the durational patterns of native Japanese speakers learning English, with a focus on two major prosodic effects: phrase-final lengthening and stresstimed shortening. To investigate the relative contribution of these effects, a production experiment was conducted, adapting the methodological framework of Beckman and Edwards (1990). The effects of t...

A polarographic method was used to determine the effects of acetylstrophanthidin on myocardial oxygen consumption (MVO2) of 19 cat papillary muscles contracting under both afterloaded and isometric conditions. Under afterloaded conditions, acetylstrophanthidin shifted the force-velocity relation to the right and produced increments in both the extent and velocity of shortening at constant level...
