Introduction Precise assessment of left ventricular (LV) contractility during veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is crucial. However, changes in loading conditions may mask changes in LV function when assessed with load-dependent indices like LV ejection fraction (LVEF). Indeed, these indices do not reflect intrinsic LV contractility but are the result of interaction be...

We use Simonenko quantitative indices of an N -function Φ to estimate two parameters qΦ and QΦ in Orlicz function spaces L [0,∞) with Orlicz norm, and get the following inequality: BΦ BΦ−1 ≤ qΦ ≤ QΦ ≤ AΦ Aφ−1 , where AΦ and BΦ are Simonenko indices. A similar inequality is obtained in L[0, 1] with Orlicz norm.

Community indices, such as maturity or diversity, condense information regarding the structure and composition of communities into a single metric. Soil health and quality can be inferred from such indices by assuming that communities with different structure and composition function differently. Thus, these indices can be instrumental in monitoring soil and sediment quality as well as assessin...

Measurements of ventilatory function, distribution of ventilation, diffusing capacity, and lung mechanics were made on healthy middle-aged smokers and nonsmokers drawn from a randomly selected population in order to assess the effects of cigarette smoking and the interrelationships of the several indices of lung function. Although very few subjects had abnormal function, there were significant ...

Background: Analyzer has the capability to detect hemolysis, icterus, and lipemia in samples and produces semi quantitative unit less index values for hemoglobin, bilirubin, or intralipid (so-called serum indices), but these serum index functions are not intended for diagnostic purposes. With increasing amounts of the specific interfering compounds, increasing index values are generated, which ...

AIMS Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for...

When incomes are ranked in descending order the social-evaluation function corresponding to the Gini relative inequality index can be written as a linear function with the weights being the odd numbers in increasing order. We generalize this function by allowing the weights to be an arbitrary non-decreasing sequence of numbers. This results in a class of generalized Gini relative inequality ind...

background: chronic obstructive pulmonary disease (copd) is a major public health problem worldwide. smoking is the number one cause of copd; however, genetic, environmental and dietary factors contribute to the etiology of this disease. in this study, we assessed the association between three diet quality indices -the healthy eating index-2005 (hei-2005), the healthy eating index-2010 (hei-201...
