Testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. However, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. A case of intermittent testicular torsion, with a revie...

Cosmic strings inside Schwarzschild black holes in teleparallel gravity are considered.Torsion flux inside the black hole is compute like a torsion vortex on a superfluid.Since some components of torsion are singular on Schwarzschild horizon and others remain finite we compute a torsion invariant to decide whether the torsion is singular and where torsion singularities located.It is found out t...

Objective: Laparoscopic oophoropexy is performed by a minimally invasive technique that can be offered to any age premenopausal women with an appropriate indication. Adnexal torsion is an uncommon but important cause of emergency admission to the gynaecologist. Torsion of the adnexa has traditionally been treated by involved surgical excision of the affected structure, usually via laparotomy, b...

PURPOSE To introduce a standardized method for calculation of left ventricular torsion by CMR tagging and to determine the accuracy of torsion analysis in regions using an analytical model. METHODS Torsion between base and apex, base and mid, and mid and apex levels was calculated using CSPAMM tagging and Harmonic Phase tracking. The accuracy of torsion analysis on a regional basis (circumfer...

The perturbative QCD predictions concerning deep inelastic scattering at low x are summarized. The theoretical framework based on the leading log 1/x resumma-tion and k t factorization theorem is described. The role of studying final states in deep inelastic scattering for revealing the details of the underlying dynamics at low x is emphasised and some dedicated measurements, like deep inelasti...

‎In the classical group theory there is‎ an open question‎: ‎Is every torsion free n-Engel group (for n ≥ 4)‎, nilpotent?‎. ‎To answer the question‎, ‎Traustason‎ [11] showed that with some additional conditions all‎ ‎4-Engel groups are locally nilpotent‎. ‎Here‎, ‎we gave some partial‎ answer to this question on Engel fuzzy subgroups‎. ‎We show that if μ is a normal 4-Engel fuzzy‎ subgroup of ...

Gravitational stability of torsion and inflaton potential in a fourdimensional spacetime de Sitter solution in scalar-tensor cosmology where Cartan torsion propagates is investigated in detail. Inflaton and torsion evolution equations are derived by making use of a Lagrangean method. Stable and unstable modes for torsion and inflatons are found. Present astrophysical observations favour a stabl...

The dimension of any module over an algebra of affiliated operators U of a finite von Neumann algebra A is defined using a trace on A. All zero-dimensional U-modules constitute the torsion class of torsion theory (T,P). We show that every finitely generated U-module splits as the direct sum of torsion and torsion-free part. Moreover, we prove that the theory (T, P) coincides with the theory of ...

Granular materials are large sets of macroscopic particles that interact solely via contact forces. The static behavior depends on the contact network and on the surface friction forces between grains; when they are set in motion (typically by vibrations) their dynamics is dominated by inelastic collisions. For these reasons granular media show an extremely rich phenomenology, ranging from flui...

In a recent joint work with V. Turaev [6], we defined a new concept of combinatorial torsion which we called absolute torsion. Compared with the classical Reidemeister torsion, it has the advantage of having a well-determined sign. Also, the absolute torsion is defined for arbitrary orientable flat vector bundles, and not only for unimodular ones, as is classical Reidemeister torsion. In this p...
