On the analytic systole of Riemannian surfaces of finite type

open access: yes, 2017
In our previous work we introduced, for a Riemannian surface $S$, the quantity $ \Lambda(S):=\inf_F\lambda_0(F)$, where $\lambda_0(F)$ denotes the first Dirichlet eigenvalue of $F$ and the infimum is taken over all compact subsurfaces $F$ of $S$ with ...

Dismantlability of weakly systolic complexes and applications [PDF]

open access: yesarXiv, 2009
The main goal of this paper is proving the fixed point theorem for finite groups acting on weakly systolic complexes. As corollaries we obtain results concerning classifying spaces for the family of finite subgroups of weakly systolic groups and conjugacy classes of finite subgroups.

Early genetic screening and cardiac intervention in patients with cardiomyopathies in a multidisciplinary clinic

open access: yesESC Heart Failure, EarlyView.
Abstract Aims Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.

Impact on right ventricular performance in patients undergoing permanent pacemaker implantation: Left bundle branch pacing versus right ventricular septum pacing

open access: yesJournal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2614-2624, December 2022., 2022
Abstract Background The novel method of left bundle branch pacing (LBBP) has been reported to achieve better electrical and mechanical synchrony in the left ventricle than conventional right ventricular pacing (RVP). However, its effects on right ventricle (RV) performance are still unknown.

A combinatorial non-positive curvature I: weak systolicity [PDF]

open access: yesarXiv, 2013
We introduce the notion of weakly systolic complexes and groups, and initiate regular studies of them. Those are simplicial complexes with nonpositive-curvature-like properties and groups acting on them geometrically. We characterize weakly systolic complexes as simply connected simplicial complexes satisfying some local combinatorial conditions.

Systoles of Arithmetic Hyperbolic 2- and 3-Manifolds [PDF]

open access: yesarXiv, 2022
In this paper we study the systoles of arithmetic hyperbolic 2- and 3-manifolds. Our first result is the construction of infinitely many arithmetic hyperbolic 2- and 3-manifolds which are pairwise noncommensurable, all have the same systole, and whose volumes are explicitly bounded.

The derivation of systolic computations

open access: yesScience of Computer Programming, 1990
A method is presented by which systolic computations can be derived from formal specifications. These derivations proceed in a calculational manner, originating from input/output relations and guided by performance considerations. The resulting program is a network of communicating cells that are expressed in a CSP-like program notation. The derivation

Randomized trial to assess worsening renal function by adding dapagliflozin for acute decompensated heart failure

open access: yesESC Heart Failure, EarlyView.
Abstract Aims Dapagliflozin (DAPA), a sodium‐glucose co‐transporter 2 inhibitor, has been shown to reduce cardiovascular mortality among patients with chronic heart failure. We aimed to evaluate the impact on a worsening renal function (WRF) by adding DAPA as compared to standard decongestive therapy with loop diuretics alone.

Characteristics of pulsed electric field cardiac ablation porcine treatment zones with a focal catheter

open access: yesJournal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 99-107, January 2023., 2023
Abstract Objectives Pulsed electric field (PEF) therapies employ punctuated energy delivery to kill cells in a volume of tissue through mechanisms that are not dependent on thermal processes. A key component to successful cardiac ablation procedures is ensuring the generation of transmural, contiguous ablation zones, which requires in‐depth knowledge ...
