Background Exploring changes in health inequality and its determinants over time is of policy interest. Accordingly, this study aimed to decompose inequality in neonatal mortality into its contributing factors and then explore changes from 1995-2000 to 2005-2010 in Iran.   Methods Required data were drawn from two Iran’s demographic and health survey (DHS) conducted in 2000 and 2010. Normalized...

in this paper a general view of the gini decomposition is presented. in order to decompose the gini coefficient into within group inequality, between group inequality and transvariation inequality of the iranian urban and rural areas, the 2006 and 2010  micro-data and dagum (1997) method is used. the results indicate that about 48 percent of the inequality in the country as a whole has been due...

We use an estimate for character sums over finite fields of Katz to solve open problems of Montgomery and Turán. Let h ≥ 2 be an integer. We prove that inf |z k |=1 max ν=1,...,n h | n k=1 z ν k | ≤ (h − 1 + o(1)) √ n. This gives the right order of magnitude for the quantity and improves on a bound of Erd˝ os-Renyi by a factor of the order √ log n.

In this paper, a novel controller is proposed for discrete-time nonlinear systems with uncertain output-channel time delays using RBF neural networks and information entropy. The controller is designed by minimizing the quadratic Renyi entropy. The probability density function (PDF) of tracking error is estimated by Parzen windowing technique. The Jacobian information is estimated by an RBF neu...

Using a cocycle formulation, old and new ergodic parameters beyond the Lyapunov exponent are rigorously characterized. Dynamical Renyi entropies and fluctuations of the local expansion rate are related by a generalization of the Pesin formula. How the ergodic parameters may be used to characterize the complexity of dynamical systems is illustrated by some examples: clustering and synchronizatio...
