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

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 ...

Newton-Cartan Gravity and Torsion [PDF]
, 2017 We 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.

Torsion of the Gallbladder [PDF]
Journal of Gastrointestinal Surgery, 2012 A 77-year-old woman was seen with progressive abdominal pain.A CT scan was made and showed a large gallbladder extending into the right lower abdomen. Ultrasound was performed but demonstrated no gallstones. Laparoscopy showed a tordated, necrotic gallbladder that was attached to the liver only by the cystic artery and cystic duct.

Torsion of the undescended testis in a healthy adult male [PDF]
Srpski Arhiv za Celokupno LekarstvoIntroduction. Torsion of undescended testis (UDT) in adults is rare, with only several published cases so far, and represents a urological emergency. Case outlines. We present a case of UDT torsion in 31-year-old, otherwise healthy, man who had rightside

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 ...

Journal für die reine und angewandte Mathematik (Crelles Journal), 1998 We study the behaviour of analytic torsion under smooth fibrations. Namely, let F \to E \to^{f} B be a smooth fiber bundle of connected closed oriented smooth manifolds and let $V$ be a flat vector bundle over $E$. Assume that $E$ and $B$ come with Riemannian metrics and $V$ comes with a unimodular (not necessarily flat) Riemannian metric. Let $ _{an}(

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 ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 One edge of an elastic rod is inserted into a friction-less and fitting socket head, whereas the other edge is subjected to a torque, generating a uniform twisting moment. It is theoretically shown and experimentally proved that, although perfectly smooth, the constraint realizes an expulsive axial force on the elastic rod, which amount is independent ...

Preoperative diagnosis of a torsioned accessory spleen
Journal of Medical Ultrasound, 2021 We report a case of a 12-year-old boy with an accessory spleen torsion. He presented with left-sided abdominal pain after trauma. A 4 cm oval mass without contrast enhancement was detected on contrast-enhanced computed tomography (CT), and ultrasound (US)
