Friedmann-like universes with torsion [PDF]
The European Physical Journal C, 2018 We consider spatially homogeneous and isotropic cosmologies with non-vanishing torsion, which assumes a specific form due to the high symmetry of these universes.

Journal of High Energy Physics, 2007 Z_NxZ_M orbifold models admit the introduction of a discrete torsion phase. We find that models with discrete torsion have an alternative description in terms of torsionless models. More specifically, discrete torsion can be 'gauged away' by changing the shifts by lattice vectors.

Newton-Cartan gravity and torsion [PDF]
, 2017 A bstractWe compare the gauging of the Bargmann algebra, for the case of arbitrary torsion, with the result that one obtains from a null-reduction of General Relativity.

Testicular Torsion in the Emergency Room: A Review of Detection and Management Strategies
Open Access Emergency Medicine, 2020 Testicular torsion is a challenging and time-sensitive diagnosis that is encountered frequently in daily practice, especially in the emergency room. A thorough history, the presence of a painful and swollen testis and testicular ultrasonography plays a ...

Torsion Elements and Torsionable Hypermodules
Mathematics, 2023 This article is motivated by the recently published studies on divisible hypermodules and falls in the area of hypercompositional algebra. In particular, it focuses on the torsion elements in Krasner hypermodules. First, we define the concept of a torsion element over a hypermodule, and based on it, we introduce a new class of hypermodules, namely the ...

Covariant formulation of scalar-torsion gravity [PDF]
, 2018 We consider a generalized teleparallel theory of gravitation, where the action contains an arbitrary function of the torsion scalar and a scalar field, $f(T,\phi)$, thus encompassing the cases of $f(T)$ gravity and nonminimally coupled scalar field as ...

Torsion or not torsion, that is the question [PDF]
International Journal of Modern Physics D, 2016 A hypothesis of general relativity (GR) is that spacetime torsion vanishes identically. This assumption has no empirical support; in fact, a nonvanishing torsion is compatible with all the experimental tests of GR. The first part of this essay specifies the framework that is suitable to test the vanishing-torsion hypothesis, and an interesting ...

Communications in Contemporary Mathematics, 2001 This paper achieves, among other things, the following: • It frees the main result of [9] from the hypothesis of determinant class and extends this result from unitary to arbitrary representations. • It extends (and at the same times provides a new proof of) the main result of Bismut and Zhang [3] from finite dimensional representations of Γ to ...

THE VALUE OF SIGNS AND SYMPTOMS IN THE DIAGNOSIS OF SPERMATIC CORD TORSION [PDF]
Basrah Journal of Surgery, 2015 The aim of this study is to evaluate the most useful clinical signs and symptoms in the diagnosis of spermatic cord torsion, and so decreasing unnecessary surgical exploration and testicular loss rates for these patients.
