The Universe is homogeneous and isotropic on large scales, so those scales it usually modelled as a Friedmann-Lemaítre-Robertson-Walker (FLRW) space-time. non-linearity of the Einstein field equations raises concern over averaging small-scale deviations form homogeneity isotropy, with possible implications applicability FLRW metric to Universe, even scales. Here I present technique, based multi...

Abstract We present a symbolic algorithmic approach that allows to compute invariant manifolds and corresponding reduced systems for differential equations modeling biological networks which comprise chemical reaction cellular biochemistry, compartmental models pharmacology, epidemiology ecology. Multiple time scales of given network are obtained by scaling, based on tropical geometry. Our redu...

This study reports psychometric properties and derivation of norms for a Persian version of the Multiple Intelligence Developmental Assessment Scales (MIDAS) for Adults. After examining and confirming equivalency between English and Persian versions, translated and validated by Saeidi, Ostovar, Shearer, and Asghari Jafarabadi (2015), the scale was administered to a sample (N = 2146), including ...
