Differences in Femoral Torsion Among Various Measurement Methods Increase in Hips With Excessive Femoral Torsion

Clinical Orthopaedics and Related Research, 2019
Background Correct quantification of femoral torsion is crucial to diagnose torsional deformities, make an indication for surgical treatment, or plan the amount of correction.

Adnexal Torsion in Adolescents: ACOG Committee Opinion No, 783.

Obstetrics and Gynecology, 2019
Adnexal torsion is the fifth most common gynecologic emergency. The most common ovarian pathologies found in adolescents with adnexal torsion are benign functional ovarian cysts and benign teratomas. Torsion of malignant ovarian masses in this population

Microplastic leachates impair behavioural vigilance and predator avoidance in a temperate intertidal gastropod

Biology Letters, 2018
Microplastics are a ubiquitous source of contaminations in marine ecosystems, and have major implications for marine life. Much effort has been devoted to assessing the various effects of microplastics on marine life.

Chern-Simons electrodynamics in (2+1)-spacetime with torsion [PDF]

arXiv, 1998
Chern-Simons electrodynamics in 2+1-spacetimes with torsion is investigated. We start from the usual Chern-Simons (CS) electrodynamics Lagrangian and Cartan torsion is introduced in the covariant derivative and by a direct coupling of torsion vector to the CS field.

Analytic Torsion for Quaternionic manifolds and related topics [PDF]

arXiv, 1997
In this paper we show that the Ray-Singer complex analytic torsion is trivial for even dimensional Calabi-Yau manifolds. Then we define the quaternionic analytic torsion for quaternionic manifolds and prove that they are metric independent. In dimension four, the quaternionic analytic torsion equals to the self-dual analytic torsion.

Decomposition of torsion pairs on module categories [PDF]

arXiv, 2012
In this article, we generalize the concept of torsion pairs and study its structure. As a trial of obtaining all torsion pairs, we decompose torsion pairs by projective modules and injective modules. Then we calculate torsion pairs on the algebra KAn and tub categories.
