Wing bone laminarity is not an adaptation for torsional resistance in bats [PDF]

open access: yesPeerJ, 2015
Torsional loading is a common feature of skeletal biomechanics during vertebrate flight. The importance of resisting torsional loads is best illustrated by the convergence of wing bone structure (e.g., long with thin walls) across extant bats and birds ...

Microstructure and cross-sectional shape of limb bones in Great Horned Owls and Red-tailed Hawks: how do these features relate to differences in flight and hunting behavior? [PDF]

open access: yesPLoS ONE, 2014
The Red-tailed Hawk and Great Horned Owl are two species of raptor that are similar in body size, diet, and habitat. Both species use their hindlimbs during hunting, but differ in foot morphology, how they approach and immobilize prey, and the average ...

Recurrence Quantification Analysis as a Form of Postural Control Assessment: A Systematic Review

open access: yesApplied Sciences, 2023
Human postural control is commonly assessed by center of pressure (CoP) displacement analysis. However, traditional linear parameters do not provide a complete picture of postural control, so a number of nonlinear analyses have been introduced.
