Measurement of table feed speed in modern CT. [PDF]

open access: yesJ Appl Clin Med Phys, 2014
The purpose of this study was to develop and evaluate a noninvasive method to assess table feed speed (mm's) in modern commercial computed tomography (CT) systems. The table feed (mm/rotation) was measured at selected nominal table feed speeds, given as low (26.67 mm/s), intermediate (48.00 mm/s), and high (64.00 mm/s), by utilizing a computed ...

Feeding with speed: prey capture evolution in cichilds [PDF]

open access: yesJournal of Evolutionary Biology, 2006
AbstractThe diversity of both the locomotor and feeding systems in fish is extensive, although little is known about the integrated evolution of the two systems. Virtually, all fish swim to ingest prey and all open their buccal cavity during prey capture, but the relationship between these two ubiquitous components of fish feeding strikes is unknown ...
