Geometric mechanics involves the application of geometric and symmetry techniques to the study of Lagrangian or Hamiltonian mechanics. The goal of computational geometric mechanics is to construct computational algorithms which preserve the geometric properties of mechanical systems [1]. My research is focused on developing computational geometric methods for numerical integration, optimal cont...

Shake, rattle, and help each other along In classical statistical mechanics, the deterministic dynamics of a many-body system are replaced by probabilistic description. Chvykov et al. work toward similar description for nonequilibrium self-organization collectives active particles. these systems, continuously input energy drives localized fluctuations, but larger-scale ordering can emerge, such...

Understanding principles of neurolocomotion requires the synthesis neural activity, sensory feedback, and biomechanics. The nematode \textit{C. elegans} is an ideal model organism for studying locomotion in integrated neuromechanical setting because its circuit has a well-characterized modular structure undulatory forward swimming gait adapts to surrounding fluid with shorter wavelength higher ...

patients with chronic low back pain (lbp) hold various knowledge, perceptions and beliefs about their pain which are based on prior learning and social conditions. since lbp is a bio- psycho-social phenomenon and there are not any reports about awareness and attitude of iranian patients’ views regarding it, this descriptive study was employed to earn this information p to apply its results in h...

Locomotion in an organism is a consequence of the coupled interaction between brain, body and environment. Motivated by qualitative observations and quantitative perturbations of crawling in Drosophila melanogaster larvae, we construct a minimal integrative mathematical model for its locomotion. Our model couples the excitation-inhibition circuits in the nervous system to force production in th...
