Cormorants are water birds that forage by submerged swimming in search and pursuit of fish. Underwater they swim by paddling with both feet simultaneously in a gait that includes long glides between consecutive strokes. At shallow swimming depths the birds are highly buoyant as a consequence of their aerial lifestyle. To counter this buoyancy cormorants swim underwater with their body at an ang...

BACKGROUND Many microorganisms, including myxobacteria, cyanobacteria, and flexibacteria, move by gliding. Although gliding always describes a slow surface-associated translocation in the direction of the cell's long axis, it can result from two very different propulsion mechanisms: social (S) motility and adventurous (A) motility. The force for S motility is generated by retraction of type 4 p...

Primary adhesive capsulitis is a term used to describe an insidious onset of pain and movement restriction in the glenohumeral joint. The objective of this study is to compare the effectiveness of anterior versus posterior glide mobilization techniques for improving functional activity of the shoulder in patients with adhesive Capsulitis. In this study a total number of 20 subjects were randoml...

A number of accounts of human auditory perception assume that listeners use prior stimulus context to generate predictions about future stimulation. Here, we tested an auditory pitch-motion hypothesis that was developed from this perspective. Listeners judged either the time change (i.e., duration) or pitch change of a comparison frequency glide relative to a standard (referent) glide. Under a ...

I am in terested in establishing a framework for studying dynamics and control of underwater gliders. I am focussing on dedicated gliding vehicles that hav e the ability to change mass (or v olume) for buoyancy control and to redistribute mass for attitude control. Later on it is of in terest to consider vehicles that use glide maneuvers to complement more traditional methods of control actuati...

Cell specification in the nervous system requires patterning genes dictating spatio-temporal coordinates as well as fate determinants. In the case of neurons, which are controlled by the family of proneural transcription factors, binding specificity and patterned expression trigger both differentiation and specification. In contrast, a single gene, glide cell deficient/glial cell missing (glide...
