Shape matters in cooperation
Why do organisms cooperate with each other? This seemingly simple question has motivated a staggering amount of theoretical and experimental research. When cooperating with others carries a direct fitness cost for the individual, natural selection should act against such behavior. However, cooperation is widespread across natural systems, from birds and bees to bacteria. Past research has ident...
متن کاملMicrorheology of colloidal dispersions: Shape matters
e consider a “probe” particle translating at constant velocity through an otherwise quiescent ispersion of colloidal “bath” particles, as a model for particle-tracking microrheology experiments n the active nonlinear regime. The probe is a body of revolution with major and minor semiaxes and b, respectively, and the bath particles are spheres of radii b. The probe’s shape is such that hen its m...
متن کاملWhen Shape Matters: Deformations of Tiling Spaces
We investigate the dynamics of tiling dynamical systems and their deformations. If two tiling systems have identical combinatorics, then the tiling spaces are homeomorphic, but their dynamical properties may differ. There is a natural map I from the parameter space of possible shapes of tiles to H of a model tiling space, with values in R. Two tiling spaces that have the same image under I are ...
متن کاملWhy shape matters in granular compaction
We present a stochastic model of dynamically interacting grains in one dimension, in the presence of a low vibrational intensity, to investigate the effect of shape on the statics and dynamics of the compaction process. Regularity and irregularity in grain shapes are shown to be centrally important in determining the statics of close-packing states, as well as the nature of zeroand low-temperat...
متن کاملPitch Contour Shape Matters in Memory
The Autosegmental-metrical model of prosody [1,2] holds that pitch melodies can be modeled with level low and high tones; information about the shape of the pitch contour is not part of the phonological representation. Yet recent results [3,4] show that contour shape affects the perception of tone height and timing. A pitch plateau that maintains a level pitch at its peak will be perceived as h...
