Although the Brief Resilient Coping Scale (BRCS) has been validated in some European and American countries, there are no studies that evaluate its factorial invariance among different nations. In this sense, the objective of the study is to evaluate

We construct a class of knot solutions of the gravitoelectromagnetic (GEM) equations in vacuum in the linearized gravity approximation by analogy with the Ra\~{n}ada-Hopf fields. For these solutions, the dual metric tensors of the bi-metric geometry

This study tests for measurement invariance of impulsivity assessed by the Barratt Impulsiveness Scale (BIS) across Black and White adults with cocaine use disorder and examines the association of BIS impulsivity with treatment retention and outcomes

The aim of this study was to examine the psychometric properties of the Disgust Scale-Revised (DS-R) in a large community sample in Italy. Participants (845 Italians, aged 20–46; 50.1% women) completed a battery of self-report questionnaires: the D

Berwald geometries are Finsler geometries close to (pseudo)-Riemannian geometries. We establish a simple first order partial differential equation as necessary and sufficient condition, which a given Finsler Lagrangian has to satisfy to be of Berwald

In the 90s, based on presentations of 3-manifolds by Heegaard diagrams, Kuperberg associated a scalar invariant of 3-manifolds to each finite dimensional involutory Hopf algebra over a field. We generalize this construction to the case of involutory

There have been over 30 studies and two meta-analyses comparing social anxiety between Asian Americans and European Americans. However, few have investigated the invariance of social anxiety measures that would make these comparisons appropriate. In

The proposed work enhances the feature point detection in the scalar-invariant feature transformation (SIFT). The sequence of steps in the SIFT algorithm drops most of the feature points in the low-contrast regions of the image. This paper provides a

We propose a new scalar and shift transform invariant test statistic for the high-dimensional two-sample location problem. Theoretical results and simulation studies show the good performance of our test under certain circumstances.
