Routes of public transport and the situation of tuberculosis in Lima, Peru

Revista Peruana de Medicina Experimental y Salud Pública, 2015
In order to determine the association between the number of formal urban public transport routes and the situation of tuberculosis (TB) in each district of Lima, a correlational analysis and linear regression model between the two variables was performed.

Around Choi inequalities for positive linear maps

Linear Algebra and its Applications, 2011
Let \(\Phi\) be a unital positive linear map between two matrix algebras \({\mathcal A}\) and \({\mathcal B}\) and let \(A\in {\mathcal A}\) be positive. \textit{J.-C.\thinspace Bourin} and \textit{E.\,Ricard} [Linear Algebra Appl.\ 433, No.\,3, 499--510 (2010; Zbl 1208.15019)] showed that, if \(0 \leq p \leq q\), then \(|\Phi(A^p)\Phi(A^q)| \leq \Phi ...

A general composite iterative method for generalized mixed equilibrium problems, variational inequality problems and optimization problems

Journal of Inequalities and Applications, 2011
In this article, we introduce a new general composite iterative scheme for finding a common element of the set of solutions of a generalized mixed equilibrium problem, the set of fixed points of an infinite family of nonexpansive mappings and the set of ...

Schmidt states and positivity of linear maps

, 2005
Using pure entangled Schmidt states, we show that m-positivity of a map is bounded by the ranks of its negative Kraus matrices. We also give an algebraic condition for a map to be m-positive. We interpret these results in the context of positive maps as entanglement witnesses, and find that only 1-positive maps are needed for testing entanglement.

Multiband Spectropolarimetry of Lunar Maria, Pyroclastics, Fresh Craters, and Swirl Materials

The Astronomical Journal
Imaging polarimetry is a well-known method for examining the small-scale structure of the surface regolith of airless celestial bodies. In this study, we examine (for the first time) the wavelength-dependent polarization behavior of selected lunar areas,

Operator quadratic mean and positive linear maps

Journal of Mathematical Inequalities
Summary: This paper presents several bounds for unital positive linear mappings and the socalled quadratic mean. Some of these results can be viewed as sub-multiplicative inequalities, while others are Cauchy-Schwarz-type inequalities. Related results that treat the tensor products will be presented, too.

Decisive significance of lineaments on groundwater occurrence in the Khapri watershed of Deccan Volcanic Province (DVP), district Dangs, Western India

Discover Geoscience
This study investigates the influence of geological lineaments on groundwater occurrence in the Khapri watershed, Dangs district, Gujarat, where rugged terrain and less transmissible basaltic rocks limit infiltration despite high rainfall (2000 mm ...
