AbstractIn this paper, we evaluate the performance of a spatial multiresolution analysis (SMA) method, that behaves like variable bandwidth kernel density estimation (KDE) for hazardous r...

INTRODUCTION Quantifying years of potential life lost (YPLL) highlights childhood causes of mortality and provides a simple method to identify important causes of premature death. METHODS CDC analyzed data from the National Vital Statistics System multiple cause of death files for 2000-2009. RESULTS An average of 890YPLL were lost each year due to unintentional injuries for every 100,000 pe...

AbstractIn a previous article (ref. [1]) the authors discussed the application of operator-splitting methods to the timediscretization of those mathematical relations describing the behavior of elasto-dynamical systems with friction, focusing on one-degree of freedom models. The main goal of the present article is to generalize the methodology discussed in ref. [1]; there are no conceptual diff...

AbstractIn this paper we introduce the subclass K(μ, γ, η, α, β) of β-uniformly convex and β-uniformly starlike functions which are analytic and multivalent with negative coefficients defined by using fractional calculus operators. Characterization property exhibited by the functions in the class and the results of modified Hadamard product are discussed. Connections with the popular subclasses...

AbstractIn this paper, we introduce a new class K(α, β) of uniformly convex functions defined by a certain fractional calculus operator. The class has interesting subclasses like β-uniformly starlike, βuniformly convex and β-uniformly pre-starlike functions. Properties like coefficient estimates, growth and distortion theorems, modified Hadamard product, inclusion property, extreme points, clos...

In mice, recent thymic emigrants (RTEs) make up a large part of the naïve T cell pool and have been suggested to be a distinct short-lived pool. In humans, however, the life span and number of RTEs are unknown. Although (2)H(2)O labeling in young mice showed high thymic-dependent daily naïve T cell production, long term up- and down-labeling with (2)H(2)O in human adults revealed a low daily pr...

AbstractIn this study, a two-step approximate Bayesian computation (ABC) updating framework using dynamic response data is developed. In framework, the Euclidian and Bhattacharyya distances ar...

AbstractIn this work, a new method is presented as a mingle of Principal Component Analysis (PCA) and Multi-Fractal Dimension analysis (MFD) for feature extraction. Proposed method makes use of best decision taken from both the methods and make use of fewer and effective features than traditional algorithms without compromise in recognition accuracy. In order to ease the pre-processing we contr...

AbstractIn this research we consider the problem of scheduling rounds of a non-professional table-tennis league. We formalize the problem in terms of a timetabling optimization problem. Then we solve this highly constrained problem with a permutation based Genetic Algorithm for which feasibility preserving operators are defined. Since coding and operators cannot warrant feasibility in every cas...

AbstractIn spite of their non-isotropic nature, local growths based on 4-connected or 8-connected neighborhoods are frequently used for binary image dilation, mostly because they are very easy to implement. Altough better dilation techniques exist, they usually require bigger masks, more complex routines, exotical grid definitions or globally processing the image. In this article we propose a n...
