Spherical surfaces with conical points: systole inequality and moduli spaces with many connected components

Geometric and Functional Analysis, 2018
In this article we address a number of features of the moduli space of spherical metrics on connected, compact, orientable surfaces with conical singularities of assigned angles, such as its non-emptiness and connectedness. We also consider some features

Systolic model and systolic geometry

1988., IEEE International Symposium on Circuits and Systems, 2003
The lack of a precise model for systolic algorithms has been hindering progress in the automatic synthesis of systolic arrays. The author proposes a model that encompasses a very large class of algorithms but is still restrictive enough so that mappings of such algorithms onto systolic architectures whose time performance is within a known factor of ...

Translating systolic arrays into instruction systolic arrays

Proceedings of the 1988 ACM sixteenth annual conference on Computer science - CSC '88, 1988
An instruction systolic array is a programmable systolic array. Instructions and mask bits are pumped through the array as well as data. It offers cost-benefit advantages over systolic arrays because one array can be used for multiple applications.

CLINICAL OBSERVATIONS ON THE DYNAMICS OF VENTRICULAR SYSTOLE: I. AURICULAR FIBRILLATION

, 1923
According to recent physiologic investigations (Wiggers 1 ), ventricular systole may be divided into a period of isometric contraction and a period of ejection, the latter being again divided into a phase of maximum and reduced ejection.

Systolic Click and Late Systolic Murmur in a Young Woman

Chest, 1974
An asymptomatic young woman with a systolic click and late systolic murmur is discussed. Phonocardiograms, multiple cardiograms, carotid tracing, and echocardiogram revealed a prolapse of the posterior mitral leaflet. Angiocardiogram confirmed the diagnosis made by use of the noninvasive methods.

CLINICAL OBSERVATIONS ON THE DYNAMICS OF VENTRICULAR SYSTOLE: II. HYPERTENSION

, 1924
The phases of ventricular systole have been fully studied in the experimental animal under various dynamic conditions. Wiggers, 1 in a recent critical report, not only analyzed the effect of general arterial constriction, but also studied the results of ...
