A Step towards an Easy Interconversion of Various Number Systems [PDF]

open access: yesarXiv, 2011
Any system that is used for naming or representing numbers is a number system, also known as numeral system. The modern civilization is familiar with decimal number system using ten digits. However digital devices and computers use binary number system instead of decimal number system, using only two digits namely, 0 and 1 based on the fundamental ...

eGFR slope as predictor of mortality in heart failure patients

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1217-1226, April 2025.
Abstract Aims Heart failure (HF) leads to an imbalance between heart and kidney function, resulting in poor outcomes. However, the prognostic significance of the estimated glomerular filtration rate (eGFR) trajectory in HF patients remains unclear. We analysed electronic health records (EHRs) of real‐world HF patients, assessing eGFR trajectories and ...

Nonlinear Modal Decoupling of Multi-Oscillator Systems with Applications to Power Systems [PDF]

open access: yesarXiv, 2016
Many natural and manmade dynamical systems that are modeled as large nonlinear multi-oscillator systems like power systems are hard to analyze. For such a system, we propose a nonlinear modal decoupling (NMD) approach inversely constructing as many decoupled nonlinear oscillators as the system oscillation modes so that individual decoupled oscillators ...

Epidemiology of hospitalized heart failure in France based on national data over 10 years, 2012–2022

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1283-1294, April 2025.
Abstract Aims We aim to describe the incidence of HF hospitalization in France in the post‐pandemic era, the prevalence of HF cases and patients' characteristics, management and outcomes while focusing on sex, age and socio‐economic differences and to analyse time‐trends between 2012 and 2022.

The effectiveness of zofenopril in patients with cardiovascular disease [PDF]

open access: yesСистемные гипертензии, 2014
Hyperactivity of the renin-angiotensin-aldosterone system plays an important role in the pathogenesis of any cardiovascular disease. Angiotensin - converting enzyme inhibitors are the main drugs among many medicines influencing the activity of the renin ...

Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled
