Impact of Ischemic and Valvular Heart Disease on Atrial Excitation:A High‐Resolution Epicardial Mapping Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe influence of underlying heart disease or presence of atrial fibrillation (AF) on atrial excitation during sinus rhythm (SR) is unknown. We investigated atrial activation patterns and total activation times of the entire atrial epicardial ...

Complexity promotes stability in mutualistic networks through weaker mutualistic dependencies: Insights from Generalized Modelling

Journal of Animal Ecology, EarlyView.
We show that complexity, but not nestedness or modularity, increase dynamical stability of mutualistic networks, mainly through a weakening in mutualistic dependencies with complexity. Abstract Mutualistic networks provide essential contributions to long‐term ecosystem functioning and food security, but Anthropocene stressors continue to alter their ...

A cavotricuspid isthmus-dependent flutter with an unexpected left atrial activation sequence: A case report

Heart Vessels and Transplantation
Objective: The isthmus-dependent right atrial flutter is a known arrhythmia, but few studies described the sequence activation of the left atrium. It is well established that the interatrial connection occurs through different pathways: the coronary ...

VAT cuts as emergency policy intervention: evidence from the UK case

Fiscal Studies, EarlyView.
Abstract In July 2020, the UK government reduced the rate of value‐added tax on hospitality services from 20 per cent to 5 per cent as an emergency policy intervention. Using a novel dataset of detailed hotel room characteristics in the UK and three European comparison countries, we estimate how much of the tax cut was passed on to consumers via a ...

Electrophysiological models for the heterogeneous canine atria: computational platform for studying rapid atrial arrhythmias.

, 2011
Heterogeneity in the electrical action potential (AP) properties can provide a substrate for atrial arrhythmias, especially at rapid pacing rates. In order to quantify such substrates, we develop a family of detailed AP models for canine atrial cells. An

Do Sustainability Restatements Impair Financial Analysts’ Earnings Forecast Accuracy?

Abacus, EarlyView.
This paper examines empirically the association between sustainability restatements (SRS), that is, restatements in sustainability reports, and analyst forecast accuracy, measured by analysts’ forecast errors for current‐year earnings. We find that SRS are related to greater earnings forecast errors, especially when they are related to environmental or

The effect of addback statutes on CEO compensation

Accounting &Finance, Volume 65, Issue 1, Page 793-818, March 2025.
Abstract Exploiting the adoption of addback statutes, which occurred at different times, as exogenous shocks to corporate taxable income, we examine the effect of tax policy changes on the compensation of chief executive officers (CEOs). We provide evidence that CEOs of firms headquartered in states affected by addback statutes experienced a decrease ...

Analysis of drug-induced and spontaneous cardioversions reveals similar patterns leading to termination of atrial fibrillation

Frontiers in Physiology
IntroductionThe mechanisms leading to the conversion of atrial fibrillation (AF) to sinus rhythm are poorly understood. This study describes the dynamic behavior of electrophysiological parameters and conduction patterns leading to spontaneous and ...

Corneal transplantation: Restoring sight to the blind

Acta Ophthalmologica, EarlyView.
Abstract Corneal blindness is one of the leading causes of vision loss worldwide. Transplantation of the cornea can restore vision and make blind patients see again. Corneal transplant surgery has undergone major evolution in recent decades with the advent of minimally invasive lamellar surgical approaches such as DMEK and DALK.

Biatrial Tachycardia Following Linear Anterior Wall Ablation for the Perimitral Reentry: Incidence and Electrophysiological Evaluations

, 2015
Biatrial Reentry After Anterior LA Line Ablation IntroductionA left atrial (LA) anterior ablation line (AnL), connecting the mitral annulus and right pulmonary veins or a roof line, has been suggested as an alternative to mitral isthmus (MI) ablation for
