Twisting of a Pristine α-Fe Nanowire: From Wild Dislocation Avalanches to Mild Local Amorphization
The torsion of pristine α-Fe nanowires was studied by molecular dynamics simulations. Torsion-induced plastic deformation in pristine nanowires is divided into two regimes.

Abstract We introduce a trilinear functional of differential one-forms for a finitely summable regular spectral triple with a noncommutative residue. We demonstrate that for a canonical spectral triple over a closed spin manifold it recovers the torsion of the linear connection.

Wandering spleen is a rare cause of acute or chronic recurrent abdominal pain with a risk of splenic torsion and infarction. We describe a case of a 14-year-old girl with chronic recurrent abdominal pain with a palpable spleen in normal position on the ...

Abstract In this paper, we study Chow motives whose identity map is killed by a natural number. Examples of such objects were constructed by Gorchinskiy and Orlov [ 10]. We introduce various invariants of torsion motives, in particular, the $p$-level.

The analytic torsion of a disc [PDF]
We study the Reidemeister torsion and the analytic torsion of the $m$ dimensional disc in the Euclidean $m$ dimensional space, using the base for the homology defined by Ray and Singer in \cite{RS}. We prove that the Reidemeister torsion coincides with a power of the volume of the disc.

In this article we explain discrete torsion. Put simply, discrete torsion is the choice of orbifold group action on the B field. We derive the classification H^2(G, U(1)), we derive the twisted sector phases appearing in string loop partition functions, we derive M.
