Museum Notes: Kangaroo Rat Colonies Found

Notes on Restricted P Colonies

We continue the investigation of P colonies introduced in [7], a class of abstract computing devices composed of independent agents, acting and evolving in a shared environment. We determine the generative power of P colonies with one resp. two objects inside each agent owing some special restrictions to the number of agents and type of programs. I{eywords: P colony, membrane systems, generativ...

Kangaroo rat locomotion: design for elastic energy storage or acceleration?

Mechanical stresses (force/cross-sectional area) acting in muscles, tendons and bones of the hindlimbs of kangaroo rats (Dipodomys spectabilis) were calculated during steady-speed hops and vertical jumps. Stresses were determined from both high-speed ciné films (light and X-ray) and force plate recordings, as well as from in vivo tendon force recordings. Stresses in each hindlimb support elemen...
