Primary pulmonary hypertension is a rare disease in childhood associated with a poor prognosis. However, during the past 10 years, pulmonary vasodilator treatment has somewhat improved its prognosis. Long term continuous infusion of prostacyclin (epoprostenol) has been shown to improve physical capacity and to reduce mortality in primary and secondary pulmonary hypertension. It has been reporte...

A useful result about leftmost and rightmost paths in two dimensional bond percolation is proved. This result was introduced without proof in [5] in the context of the contact process in continuous time. As discussed here, it also holds for several related models, including the discrete time contact process and two dimensional site percolation. Among the consequences are a natural monotonicity ...

We discuss robust estimates based on leverage downweighting of the coe cients in logistic regression case-control studies when the true predictor X is an unobserved continuous random variable, and instead a surrogateW is observed with nondi erential measurement error. The asymptotic theory of the estimates is derived, and consistent standard error estimates obtained. An illustrative example sho...

This article exploits positive systems theory in the search for Zames–Falb multipliers analysis of discrete-time Lurie systems, where nonlinearity is assumed to be slope-restricted. Although a similar problem has been tackled continuous time context, results take different form and require somewhat approach overcome certain technical problems. The work two compelling features: (i) arising algor...

the aim of this paper is to introduce the concepts of fuzzy upper and fuzzy lower almost continuous, weakly continuous and almost weakly continuous multifunctions. several characterizations and properties of these multifunctions along with their mutual relationships are established in $l$-fuzzy topological spaces
