background: assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia.   objective: a myocardial performance index (mpi) or tei index has been developed for adu...

A statistical analysis of differential Doppler estimation is presented that includes the particular features found in aeroacoustic signals from ground vehicles, namely a sum-of-harmonics signal that is randomly scattered by the atmosphere. We use a physics-based statistical model for the scattering to derive the Cramér-Rao bound (CRB) on differential Doppler estimation as a function of the atmo...

Advanced methods of geo-atmospheric preprocessing have become available in the past years and increasingly are applied to AVIRIS airborne imagery. Both, the geometric as well as the atmospheric part of the preprocessing have their specific impact on data quality which should be aware to scientists using such corrected data. An integral geoatmospheric correction has been developed in a joint eff...

BACKGROUND Common conditions such as obesity and hypertension result in hemodynamic alterations that will induce remodeling of the left ventricle (LV). However, differences between the genders in the relationship of hemodynamics to LV geometry are not well known.The present study aims to investigate differences between the genders in this respect, in a sample of elderly persons. METHODS Echoc...

conclusions neither of studied variables was perfect to differentiate cirrhotic patients with and without evs. endoscopy is still the gold standard diagnostic method for diagnosing esophageal varices in patients with cirrhosis. it seems that some of the splenoportal doppler indices are promising, but more research and evaluation is necessary. results forty-four patients were male and 22 female....
