Open Heart, 2019 Objective Diastolic-systolic velocity ratio (DSVR) is a resting index to assess stenoses in the left anterior descending artery (LAD). DSVR can be measured by echocardiographic or intracoronary Doppler flow velocity.

Complexity in Bolza surface [PDF]
arXiv, 2023 A surface in the Teichm\"uller space, where the systole function attains its maximum, is called a maximal surface. For genus two there exists a unique maximal surface which is called the Bolza surface. In this article, we study the complexity of the set of systolic geodesics on the Bolza surface.

IEEE Transactions on Biomedical Engineering, 2012 Previous studies have shown that cardiac microacceleration signals, recorded either cutaneously, or embedded into the tip of an endocardial pacing lead, provide meaningful information to characterize the cardiac mechanical function.

Metaphors in systolic geometry [PDF]
arXiv, 2010 This is an expository essay about systolic geometry. It describes a central theorem in the subject and why the proof is difficult. Then it discusses different metaphors which suggest ways to approach the problem. The metaphors connect the systolic inequality to minimal surfaces, topological dimension, scalar curvature, and hyperbolic geometry.

FuSeConv: Fully Separable Convolutions for Fast Inference on Systolic Arrays [PDF]
arXiv, 2021 Both efficient neural networks and hardware accelerators are being explored to speed up DNN inference on edge devices. For example, MobileNet uses depthwise separable convolution to achieve much lower latency, while systolic arrays provide much higher performance per watt.

ESC Heart Failure, EarlyView.Abstract Aims A novel marker left atrioventricular coupling index (LACI) has been proved to be associated with cardiovascular events in patients without history of cardiovascular disease. However, the studies on cardiac magnetic resonance‐derived LACI in hypertrophic cardiomyopathy (HCM) patients are limited, and the prognostic value of LACI has still ...

Interactions between cardiac activity and conscious somatosensory perception
, 2019 Fluctuations in the heart's activity can modulate the access of external stimuli to consciousness. The link between perceptual awareness and cardiac signals has been investigated mainly in the visual and auditory domain. Here, we investigated whether the

Hyperbolic surfaces with long systoles that form a pants decomposition [PDF]
arXiv, 2016 We present a construction of sequences of closed hyperbolic surfaces that have long systoles which form pants decompositions of these surfaces. The length of the systoles of these surfaces grows logarithmically as a function of their genus.

Systole et rayon interne des variétés hyperboliques non compactes [PDF]
, 2011 We bound two global invariants of cusped hyperbolic manifolds: the length of the shortest closed geodesic (the systole), and the radius of the biggest embedded ball (the inradius).
