Torsion of the Wandering Spleen
Acta Medica Iranica, 2009 Wandering spleen, defined as a spleen without its usual peritoneal attachments, is a rare entity. We report a 34-year-old woman with acute abdomen due to torsion of the long vascular pedicle of a wandering spleen, displaced in the abdominal cavity, and ...

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

A generalization of torsion to modules [PDF]
, 1971 The concepts of torsion and torsion-free objects have their origins in abelian group theory, where for an abelian group G the torsion subgroup T(G) of G is defined by T(G) = {x ?

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

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading
Advanced Engineering Materials, EarlyView.This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
