FlyLimbTracker: An active contour based approach for leg segment tracking in unmarked, freely behaving Drosophila
Understanding the biological underpinnings of movement and action requires the development of tools for quantitative measurements of animal behavior. Drosophila melanogaster provides an ideal model for developing such tools: the fly has unparalleled genetic accessibility and depends on a relatively compact nervous system to generate sophisticated limbed behaviors including walking, reaching, gr...
متن کاملActive Galaxies as Particle Accelerators
We present the theoretical arguments and describe the accumulating experimental evidence that jets, powered by supermassive black holes, are true cosmic accelerators. They produce photons of TeV energy, possible higher, and may be the enigmatic source of the highest energy cosmic rays. The features of the multiwavelength emission spectrum are dictated by the interactions of electrons and proton...
متن کاملActive Polymer Gel Actuators
Many kinds of stimuli-responsive polymer and gels have been developed and applied to biomimetic actuators or artificial muscles. Electroactive polymers that change shape when stimulated electrically seem to be particularly promising. In all cases, however, the mechanical motion is driven by external stimuli, for example, reversing the direction of electric field. On the other hand, many living ...
متن کاملParticle acceleration in an active medium.
When an electron moves along a vacuum channel in a dielectric material it may cause radiation to be emitted provided that its velocity is greater than the phase velocity of an electromagnetic plane wave in the medium. This is the socalled Čerenkov radiation. What a remote observer measures as electromagnetic energy comes at the expense of the particle’s kinetic energy or, in other words, the pa...
متن کاملOscillatory motions of an active deformable particle.
We investigate dynamics of an active particle in which shape deformations occur spontaneously. In two dimensions, the deformations are expanded in terms of the Fourier series and the couplings of different modes are taken into consideration truncated up to lower orders. We focus our attention on the special symmetrical structure between the coupled equations of n- and 2n-mode deformations for n...
