Objective We test the hypothesis that aspartate aminotransferase (AST) may be associated inversely with serum triglycerides (TG) and positively with high density lipoprotein (HDL) cholesterol in young athletes because athletes have larger amounts of muscle mass. Research design and methods Pearson's correlation coefficients were calculated between serum AST and alanine aminotransferase (ALT) ...

We consider the inverse problem of concentration imaging in chemical species tomography with limited data sets. The measurement setup involves simultaneous acquisition of near infrared wavelength-modulated spectroscopic measurements from a small number of pencil beams equally distributed among six projection angles surrounding the plume. We develop an approach for image reconstruction that invo...

Quadratic pencils arise in many areas of important applications. The underlying physical systems often impose inherent structures, which include the predetermined inner-connectivity among elements within the physical system and the mandatory nonnegativity of physical parameters, on the pencils. In the inverse problem of reconstructing a quadratic pencil from prescribed eigeninformation, respect...

Abstract We establish dual equivalent forms involving relative entropy, Fisher information, and optimal transport costs of inverse Santaló inequalities. show in particular that the Mahler conjecture is to some dimensional lower bound on deficit Gaussian logarithmic Sobolev inequality. also derive from existing results inequalities sharp bounds Our proofs rely duality relations between convex fu...

In this paper, we investigate the split variational inequality problem in Hilbert spaces, which an operator is ?-inverse strongly ?-monotone and another pseudomonotone. We construct iterative algorithm for solving problem. show strong convergence of suggested algorithm.

BACKGROUND Previous studies have found the socioeconomic gradient in health among adolescents to be lower than that observed during childhood and adulthood. The aim of this study was to examine income-related inequalities in health and health-related behaviour across the lifespan in England to explore 'equalisation' in adolescence. METHODS We used five years of data (2006-2010) from the Healt...
