Why walkers slip: shine is not a reliable cue for slippery ground.
(Percept Psychophys, 2006-04)
In a series of four studies, we investigated the visual cues that walkers use to predict slippery ground surfaces and tested whether visual information is reliable for specifying low-friction conditions. In Study 1, 91% ...
Computed tomography dose index and dose length product for cone-beam CT: Monte Carlo simulations.
(Journal of applied clinical medical physics, 2011-01-19)
Dosimetry in kilovoltage cone beam computed tomography (CBCT) is a challenge due to the limitation of physical measurements. To address this, we used a Monte Carlo (MC) method to estimate the CT dose index (CTDI) and the ...
Hip extensor mechanics and the evolution of walking and climbing capabilities in humans, apes, and fossil hominins.
(Proceedings of the National Academy of Sciences of the United States of America, 2018-04-02)
The evolutionary emergence of humans' remarkably economical walking gait remains a focus of research and debate, but experimentally validated approaches linking locomotor capability to postcranial anatomy are limited. In ...
Homeostasis despite instability.
(Mathematical biosciences, 2018-06)
We have shown previously that different homeostatic mechanisms in biochemistry create input-output curves with a "chair" shape. At equilibrium, for intermediate values of a parameter (often an input), a variable, Z, changes ...
