The homology systole of hyperbolic Riemann surfaces

open access: yesGeometriae Dedicata, 2011
The main goal of this note is to show that the study of closed hyperbolic surfaces with maximum length systole is in fact the study of surfaces with maximum length homological systole.

Dyssynchronous electrical and mechanical systole in patients with cirrhosis

open access: yesJournal of Hepatology, 2002
Udgivelsesdato: 2002-AprBACKGROUND/AIMS: Previous investigations have shown a prolonged QT interval in some patients with cirrhosis. The aim of this study was to investigate the relation between electrical and mechanical systole in patients with ...

On foliations of bounded mean curvature on closed three-dimensional Riemannian manifolds

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2023
The notion of systole of a foliation sys(ℱ) on an arbitrary foliated closed Riemannian manifold (M,ℱ) is introduced. A lower bound on sys(ℱ) of a bounded mean curvature foliation is given.

Local maxima of the systole function [PDF]

open access: yes, 2022
We construct a sequence of closed hyperbolic surfaces that are local maxima for the systole function in their respective moduli spaces. Their systole is arbitrarily large and the number of examples grows rapidly with the genus.

Diastolic and Systolic Longitudinal Myocardial Velocities of Healthy Racing Pigeons (Columba livia f. domestica) Measured by Tissue Doppler Imaging

open access: yesVeterinary Sciences, 2021
Tissue Doppler imaging (TDI) is a noninvasive sonographic method of acquiring and quantifying myocardial velocities. This technique is used in human and small animal medicine to diagnose cardiac diseases.

Numerical study of hemodynamics after stent implantation during the cardiac cycle

open access: yesJournal of Mechanical Engineering and Sciences, 2021
The descending aortic aneurysm is one of the most catastrophic cardiovascular emergencies resulting in high mortality worldwide. Clinical observations have pointed out that stent implantation in the sick aorta should probably allow stabilization of the ...

Accurate end systole detection in dicrotic notch-less arterial pressure waveforms [PDF]

open access: yes, 2021
peer reviewedIdentification of end systole is often necessary when studying events specific to systole or diastole, for example, models that estimate cardiac function and systolic time intervals like left ventricular ejection duration.
