Droplets climbing a rotating helical fiber.
نویسندگان
چکیده
A liquid droplet is placed on a rotating helical fiber. We find that the droplet may slide down, attach or climb up the fiber. We inspect experimentally the domain of existence of these three behaviors as a function of the geometrical characteristics of the fiber, its angle relatively to the horizontal, the wetting properties of the fluid and the rotating speed of the helix. A theoretical model is proposed in order to capture the boundaries of the experimental phase diagram.

Binary wave in a helical fiber
Axial dynamic tension of a flexible helical fiber is found to lead to a specific, extraordinary nonlinear wave consisting of two different portions. The leading portion is a quasiperiodical propagating wave with rotation opposite to the initial twist of the helix, while the rear portion is a sequence of standing waves rotating in the reverse direction. The interface is the origin of two angular...
متن کاملClimbing Fiber Signaling and Cerebellar Gain Control
The physiology of climbing fiber signals in cerebellar Purkinje cells has been studied since the early days of electrophysiology. Both the climbing fiber-evoked complex spike and the role of climbing fiber activity in the induction of long-term depression (LTD) at parallel fiber-Purkinje cell synapses have become hallmark features of cerebellar physiology. However, the key role of climbing fibe...
متن کاملCorticotropin-Releasing Factor Plays a Permissive Role in Cerebellar Long-Term Depression
This study of rat cerebellar slices yielded two lines of evidence indicating that the corticotropin-releasing factor (CRF) found in climbing fibers (CFs) is critical for the induction of long-term depression (LTD) at the parallel fiber (PF) synapses of Purkinje cells (PCs) by their conjunctive activation with either stimulation of CFs or depolarization of PCs. First, LTD induction was effective...
متن کاملClimbing Fiber Coupling between Adjacent Purkinje Cell Dendrites in Vivo
Climbing fiber discharges within the rat cerebellar cortex have been shown to display synchrony, especially for climbing fibers terminating in the same parasagittal bands. In addition, Purkinje cells which have the smallest rostrocaudal separation also seem to have the highest degree of synchrony. But this has so far only been investigated for distances down to 250 mum. In the present study, we...
متن کاملInput minimization: a model of cerebellar learning without climbing fiber error signals.
The cerebellum is critical for motor learning. Current cerebellar learning models follow the Marr/Albus paradigm, in which climbing fibers provide error signals that shape plastic synapses between parallel fibers and Purkinje cells. However, climbing fibers have slow and largely random discharge, and seem unlikely to provide error signals with resolution sufficient to guide cerebellar learning....
