INTRODUCTION Measurement of health inequities is fundamental to all health equity initiatives. It is complex because it requires considerations of ethics, methods, and policy. Drawing upon the recent developments in related specialized fields, in this paper we incorporate alternative definitions of health inequity explicitly and transparently in its measurement. We propose a three-stage approac...

This article deals with the univariate calibration problem where calibration data come from several independent sources. Such a situation arises when measurements are made using different instruments or methods, or at diierent laboratories. It is assumed that the response variable at each source is normally distributed and the relationship between the response variable and the explanatory varia...

Although age is thought to correlate with the prognosis of glioma patients, the most appropriate age-group classification standard to evaluate prognosis had not been fully studied. This study aimed to investigate the influence of age-group classification standards on the prognosis of patients with high-grade hemispheric glioma (HGG). This retrospective study of 125 HGG patients used three diffe...

A univariate trace polynomial is a in variable x and formal symbols Tr ( j ) . Such an expression can be naturally evaluated on matrices, where the are as normalized traces. This paper addresses global constrained positivity of polynomials symmetric matrices all finite sizes. tracial analog Artin's solution to Hilbert's 17th problem given: positive semidefinite quotient sums products squares tr...
