On the interaction of massive spinor particles with external electromagnetic and torsion fields [PDF]
We explore the Dirac equation in external electromagnetic and torsion fields. Motivated by the previous study of quantum field theory in an external torsion field, we include a nonminimal interaction of the spinor field with torsion.

Axial torsion and gangrene of Meckel’s diverticulum: Case report [PDF]
Introduction. Meckel’s diverticulum (MD) is the most prevalent congenital anomaly of small intestine. It develops due to the incomplete obliteration of omphalomesenterict duct which normally undergoes obliteration during the seventh week of ...

Analytic torsion and Reidemeister torsion [PDF]
We announce a proof of the conjecture of Ray and Singer that for a compact Riemannian manifold the analytic torsion and Reidemeister torsion are equal. The proof involves studying the heat equation for certain manifolds M, equipped with metrics g u , 0 < u

Unusually thick shear-softening surface of micrometer-size metallic glasses
Summary: The surface of glass is crucial for understanding many fundamental processes in glassy solids. A common notion is that a glass surface is a thin layer with liquid-like atomic dynamics and a thickness of a few tens of nanometers.

Generalized Softened Variable Angle Truss Model for PC Beams under Torsion
In a previous study, a new model (Generalized Softened Variable Angle Truss Model—GSVATM) was proposed to compute the global behavior of reinforced concrete beams under torsion, including for low loading stages. In this article, the GSVATM is extended to

Background Correct quantification of femoral torsion is crucial to diagnose torsional deformities, make an indication for surgical treatment, or plan the amount of correction.

Abstract Modifying the Yang-Mills field strength and using a recently proposed generalisation of the usual minimal coupling procedure allows a simple but non-trivial type of dynamic torsion to couple to all gauge fields in a consistent manner. This allows, for the first time, a framework in which no spinning particle is required to be exempted from ...

The Impact of Testicular Torsion on Testicular Function
Torsion of the spermatic cord is a urological emergency that must be treated with acute surgery. Possible long-term effects of torsion on testicular function are controversial.

A Canonical Quadratic Form on the Determinant Line of a Flat Vector Bundle [PDF]
We introduce and study a canonical quadratic form, called the torsion quadratic form, of the determinant line of a flat vector bundle over a closed oriented odd-dimensional manifold.
