The Relationship between Nocturnal Hypoxemia and Left Ventricular Ejection Fraction in Congestive Heart Failure Patients [PDF]
Background: sleep – disordered breathing ( SDB) is Frequently observed in Patients with Congestive heart Failure. This Study examines the Prevalence of sleep disorder in stable heart failure Patients regardless of ejection Fraction. Method: By Means of

Brown Dwarfs as Ejected Stellar Embryos: Observational Perspectives [PDF]
arXiv, 2002 We discuss a scenario in which brown dwarfs are formed like stars, except that their full collapse phases are interrupted through dynamical interactions in small multiple systems, leading to the ejection of the lightest member. This disintegration is a stochastic process, often resulting in the expulsion of newborn low mass stars, but when it occurs ...

A novel quantitative indicator of the left ventricular contraction based on volume changes of the left ventricular myocardial segments [PDF]
arXiv, 2018 Ejection fraction (EF) is commonly measured by echocardiography, by dividing the volume ejected by the heart (stroke volume) by the volume of the filled heart (end-diastolic volume). Utilizing volume changes of left myocardial segments per a cardiac cycle, physical laws and mathematical equations specific echocardiographic data, this paper serves to ...

Cavities as a source of outbursts from comets [PDF]
arXiv, 2011 Analysis of observations of natural and triggered outbursts from different comets testifies in favor of existence of large cavities with material under gas pressure below a considerable fraction of a comet's surface. Based on analysis of images of the cloud of material ejected from Comet 9P/Tempel 1 after the collision of the Deep Impact (DI) module ...
