Cranial anatomy of Acynodon adriaticus and extreme durophagous adaptations in Eusuchia (Reptilia: Crocodylomorpha)

open access: yesThe Anatomical Record, Volume 307, Issue 12, Page 3653-3684, December 2024.
Abstract Acynodon adriaticus, a small eusuchian from the Late Cretaceous of Italy, is known for its well‐preserved cranial and postcranial material. Despite its excellent preservation, many details remain hidden due to the physical overlap between the elements and matrix obliteration.

On hereditary torsion theories [PDF]

open access: yes, 1973
This thesis deals with S. E. Dickson's concept of a hereditary torsion theory for the category RM of left R-modules over an arbitrary ring R. It is proved that a class of left R-modules is a hereditary torsion class if and only if there is an injective ...

Zassenhaus conjecture for central extensions of S5 [PDF]

open access: yes, 2008
We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S5 and for the general linear group GLð2; 5Þ. The first result, together with others from the literature,

Adnexal torsion without neoplastic lesions after laparoscopic hysterectomy: A report of three cases and literature review.

open access: yes, 2020
The major risk factor for adnexal torsion is the presence of adnexal neoplasms, and torsion without a neoplastic lesion of the adnexa is rare. We report three cases of right adnexal torsion without neoplastic lesion after laparoscopic hysterectomy.

A Novel Use of Optical Coherence Tomography for the Assessment of Ocular Torsion

open access: yes, 2019
Abnormal ocular torsion is most frequently the result paresis of the fourth cranial nerve. The presence of torsion can be a barrier to fusion, in which case, surgical intervention is required for a patient to have single vision.

On The Holonomy of Connections with Skew-Symmetric Torsion

open access: yes, 2003
We investigate the holonomy group of a linear metric connection with skew-symmetric torsion. In case of the euclidian space and a constant torsion form this group is always semisimple.
