Systolic geometry of translation surfaces
, 2020 Let $S$ be a translation surface of genus $g > 1$ with $n$ cone points $(p_i)_{i=1,\ldots,n}$ with cone angle $2\pi \cdot (k_i+1)$ at $p_i$, where $k_i \in \mathbb{N}$. In this paper we investigate the systolic landscape of these translation surfaces for

Systolic invariants of groups and 2-complexes via Grushko decomposition [PDF]
arXiv, 2006 We prove a finiteness result for the systolic area of groups, answering a question of M. Gromov. Namely, we show that there are only finitely many possible unfree factors of fundamental groups of~2-complexes whose systolic area is uniformly bounded. Furthermore, we prove a uniform systolic inequality for all 2-complexes with unfree fundamental group ...

A European update on transcatheter aortic valve implantation (TAVI) in the COVID era
Journal of Anatomy, Volume 242, Issue 1, Page 50-63, January 2023., 2023 A timely review of key Transcatheter Aortic Valve Implantation (TAVI) device trials delineated by surgical risk. Abstract Minimally invasive approaches for aortic valve replacement are now at the forefront of pathological aortic valve treatment. New trials show comparability of these devices to existing therapies, not only in high‐risk surgical cohorts

Frontiers in Physiology, 2020 Increased wave reflection is an independent predictor of cardiovascular events, possibly due to effects on left ventricular (LV) function. We investigated the relationship between reflected waves in early systole, the forward decompression wave in mid ...

Boundaries of systolic groups [PDF]
arXiv, 2008 For all systolic groups we construct boundaries which are EZ--structures. This implies the Novikov conjecture for torsion--free systolic groups. The boundary is constructed via a system of distinguished geodesics in a systolic complex, which we prove to have coarsely similar properties to geodesics in CAT(0) spaces.

FlexSA: Flexible Systolic Array Architecture for Efficient Pruned DNN Model Training [PDF]
arXiv, 2020 Modern deep learning models have high memory and computation cost. To make them fast and memory-cost efficient, structured model pruning is commonly used. We find that pruning a model using a common training accelerator with large systolic arrays is extremely performance-inefficient.

Journal of Veterinary Internal Medicine, Volume 37, Issue 1, Page 47-57, January/February 2023., 2023 Abstract Background Information regarding the frequency of L waves and their prognostic relevance in dogs with secondary atrial fibrillation (AF) is limited. Hypothesis/Objectives To determine whether L waves occur and ascertain their prognostic role, as well as the role of other clinical and echocardiographic variables in dogs with AF.

Impact on variation in the direction of cuff bladder on blood pressure readings
Journal of the Practice of Cardiovascular Sciences, 2019 Introduction: Elevated blood pressure (BP)/hypertension contributes significantly to global morbidity and mortality. It is a silent killer; therefore, earlier diagnosis is imperative. A simple instrument called sphygmomanometer measures BP.
