Hindlimb biomechanics of Lagosuchus talampayensis (Archosauria, Dinosauriformes), with comments on skeletal morphology.

Lagosuchus talampayensis is a small-bodied (~0.5 m long) Late Triassic dinosauriform archosaur from Argentina. Lagosuchus long has been a pivotal taxon for reconstructing the evolution of form and function on the dinosaur lineage.

Comparison of computational pose estimation models for joint angles with 3D motion capture.

Tools to calculate human movement patterns can benefit musculoskeletal clinicians and researchers for rehabilitation assessments. The research objective of this study was to compare two human pose estimation models (HRNet, MediaPipe) against the laboratory marker-based reference standard for joint angles and range of motion (ROM) for several movement parameters. Twenty-two healthy volunteers (Female n = 16, Male n = 6), participated to compare outputs for knee and elbow kinematics.

The medical doctor (degree) apprenticeship.

In this article we explore the United Kingdom context of apprenticeships and the history of development of the use of the term apprentice in medicine. We describe the development of the Medical Doctor Degree Apprenticeship (MDDA) in England and how Anglia Ruskin University (ARU) has approached the development of the MDDA. We explore the rationale for developing the MDDA in Essex, the structure of the apprenticeship at ARU (which comprises 20% of employed time in NHS work and 80% in education undertaking the medical degree), the challenges and issues we encountered and mitigations we put in place.

Late acquisition of erect hindlimb posture and function in the forerunners of therian mammals.

The evolutionary transition from early synapsids to therian mammals involved profound reorganization in locomotor anatomy and function, centered around a shift from "sprawled" to "erect" limb postures. When and how this functional shift was accomplished has remained difficult to decipher from the fossil record alone. Through biomechanical modeling of hindlimb force-generating performance in eight exemplar fossil synapsids, we demonstrate that the erect locomotor regime typifying modern therians did not evolve until just before crown Theria.
