abstract background: multiple sclerosis (ms) is a complex inflammatory disease of the central nervous system. despite extensive research, its exact cause is unknown. one of the roles of nurses is discovery and prevention of factors related to the disease. this study aimed to investigate several food items concerning the etiology of ms in a population of ahvaz (iran). materials and methods: this...

The analysis of shape is a fundamental part of much biological research. As the field of statistics developed, so have the sophistication of the analysis of these types of data. This lead to multivariate morphometrics in which suites of measurements were analyzed together using canonical variates analysis, principal components analysis, and related methods. In the 1980s, a fundamental change be...

Metabolomics aims to provide a global snapshot of all small-molecule metabolites in cells and biological fluids, free of observational biases inherent to more focused studies of metabolism. However, the staggeringly high information content of such global analyses introduces a challenge of its own; efficiently forming biologically relevant conclusions from any given metabolomics dataset indeed ...

General multivariate periodic wavelets are an efficient tool for the approximation of multidimensional functions, which feature dominant directions of the periodicity. One-dimensional shift invariant spaces and tensor-product wavelets are generalized to multivariate shift invariant spaces on non-tensor-product patterns. In particular, the algebraic properties of the automorphism group are inves...

The convergence rate is analyzed for McCormick relaxations of compositions of the form F ̋ f , where F is a multivariate function, as established by Tsoukalas and Mitsos (JOGO, 59:633-662, 2014). Convergence order in the Hausdorff metric and pointwise convergence order are analyzed. Similar to the convergence order propagation of McCormick univariate composition functions, Bompadre and Mitsos (...
