Absolute torsion and eta-invariant
, 1999 In a recent joint work with V. Turaev (cf. math.DG/9810114) 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-defined sign. Also, the

Journal of Biomolecular NMR, 2013 A new program, TALOS-N, is introduced for predicting protein backbone torsion angles from NMR chemical shifts. The program relies far more extensively on the use of trained artificial neural networks than its predecessor, TALOS+.

Torsion of the gallbladder [PDF]
Journal of Surgical Case Reports, 2011 Torsion of the gallbladder is an uncommon condition that is rarely diagnosed pre-operatively. Here, we present the case of a 76 year old male who was found to have a complete torsion of the gallbladder, and was successfully treated with cholecystectomy.

Restrictions on torsion-spinor field theory
, 2019 Torsion propagation and torsion-spin coupling are studied in the perspective of the Velo-Zwanziger method of analysis; specifically, we write the most extensive dynamics of the torsion tensor and the most exhaustive coupling that is permitted between ...

Comparison of the Effectiveness of Chelleh Daghi Herbal Ointment and Piroxicam Gel on Ankle Sprains
Majallah-i dānishgāh-i ̒ulūm-i pizishkī-i Arāk, 2020 Background and Aim: Ankle injuries are among the most common musculoskeletal injuries in sports, accounting for 10% to 15% of all injuries. Since controlling pain and inflammation in ankle sprains is one of the main goals of treatment, we decided to ...

Revista IBRACON de Estruturas e Materiais, 2020 Most of torsion studies available are relative to pure torsion, arising from the exclusive application of a torsion moment in a concrete beam. This situation, however, is only possible in laboratories.

Effective QFT and what it tells us about dynamical torsion
, 2010 The covariantly constant spacetime torsion is one of the fields which may break Lorentz and CPT symmetry. We review the previous works on the dynamical torsion in the framework of effective quantum field theory (QFT).

The torsion of the multicell sections [PDF]
INCAS Bulletin, 2010 The paper is focused on the stress analysis of thin-walled multicell sections subjected to pure torsion. The shear flow and stiffness characteristics of the cross section for torsion are given. Example: aircraft wing section.
