INTRODUCTION There appear to be important gender differences with respect to the incidence and clinical course of arrhythmias. It has been shown that women with coronary artery disease (CAD) have a lower rate of ventricular arrhythmias and sudden cardiac death (SCD) than men. The T peak-to-end (Tpe) interval and the Tpe/QT ratio represent novel markers of arrhythmic risk that possibly correspon...

The concept of Genealogical Sorting Indexes (GSIs) was first introduced by Cummings et al. [1]. Given a set of observations belonging to different groups (represented in the form of a hierarchial tree), the Genealogical Sorting Index (GSI) value obtained for a particular group provides a quantitative measure of how closely the observations belonging to this group have clustered in the given tre...

In marine ecosystems climatic fluctuation and other physical variables greatly influence population dynamics, but differential effects of physical variables on the demographic parameters of the two sexes and different age classes are largely unexplored. We analyzed the effects of climate on the survival and recruitment of both sexes and several age classes of a long-lived tropical seabird, the ...

Aim: In this study we aimed to investigate the relationship between C-Reactive Protein (CRP)/albumin ratio, MII-1 and MII-2 indexes in hospitalization mortality due aortic dissection. Material Method: Patients who presented our emergency department with a sudden-onset, sharp stabbing chest pain diagnosed Stanford type A dissection were included study. Patients’ demographics such as age gender, ...

Data warehouses are used to store large amounts of data. This data is often used for On-Line Analytical Processing (OLAP). Short response times are essential for on-line decision support. Common approaches to reach this goal in read-mostly environments are the precomputation of materialized views and the use of index structures. In this paper, a framework is presented to evaluate different inde...

Demographic divergence between the sexes is a major consequence of sexual selection. Matrix-based demographic measures, including the sensitivity and elasticity of X (population growth rate, fitness) to survival and fertility rates are powerful indexes of intersexual divergence. Many morphological, behavioral, and ecological differences distinguish males and females in lekking long-tailed manak...
