Expanding knowledge of contracting muscle.
Muscle chapters in physiology textbooks tend to be short and narrowly focused; muscle has been portrayed as both genetically fixed and seemingly singular in function to produce work while shortening. However, the suite of muscle functions is extremely broad, including noise maker, thermogenic organ, isometric ‘lock’ and a power source for projectiles, in addition to driving locomotion. Likewise...
متن کاملVisually tracking and localizing expanding and contracting objects.
The maintenance of attention on moving objects is required for cognition to reliably engage with the visual world. Theories of object tracking need to explain on which patterns of visual stimulation one can easily maintain attention and on which patterns one cannot. A previous study has shown that it is easier to track rigid objects than objects that expand and contract along their direction of...
متن کاملExpanding and contracting optic-flow patterns and vection.
When stationary observers view an optic-flow pattern, visually induced self-motion perception (vection) and a form of motion sickness known as simulator sickness (SS), can result. Previous results suggest that an expanding flow pattern leads to more SS than a contracting pattern. Sensory conflict, a possible cause of SS, may be more salient when an expanding optic-flow pattern is viewed. An exp...
متن کاملGravitational deposition in a rhythmically expanding and contracting alveolus.
In a previous simulation, our laboratory demonstrated that the flow induced by a rhythmically expanding and contracting alveolus is highly complex (Haber S, Butler JP, Brenner H, Emanuel I, and Tsuda A, J Fluid Mech 405: 243-268, 2000). Based on these earlier findings, we hypothesize that the trajectories and deposition of aerosols inside the alveoli differ substantially from those previously p...
متن کاملOn the structure of involutive, contracting and expanding negations
Characterization and new methods of generation of bijective fuzzy negations (involutive, contracting and expanding negations) are done. The approach is based on a symmetry of involutive negations with respect to the line f(x) = x; x∈ [0; 1]. Contracting and expanding negations are given by suitable de4ections from this symmetry. c © 2002 Elsevier B.V. All rights reserved.
