Application of geometric morphometrics to analyse allometry in two species of the genus Myrmica (Hymenoptera: Formicidae)

Soil Organisms
Allometric changes in shape were analyzed in two species of the genus Myrmica using geometric morphometics. The pattern of allometry was visualized by thin plate splines (TPS) analysis.

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.

Cable Reinforcement Combined With Biologic Tuberoplasty Restores Muscle Forces and Scapular Strain in an Irreparable Rotator Cuff Tear Model: A Cadaveric Study

Arthroscopy, EarlyView.
Purpose To investigate the biomechanical impact of an irreparable rotator cuff tear and compare the isolated and combined effects of rotator cable reconstruction (CR) and biologic tuberoplasty (BioTB). Methods Eight cadaveric shoulders were tested using an ex vivo dynamic shoulder simulator in forward flexion (FF) and scapular plane abduction (SPA ...

Hyperinvariant subspaces for normaloid essential isometric operators [PDF]

In this article, we prove the existence of a non-trivial hyperinvariant subspace for a subclass of compact perturbations of scalar multiple of a partial isometry. Later, we illustrate that this class contains several important classes of operators.
