A cybernetic view on wind-up.
Wind-up is described traditionally as a frequency dependent increase in the excitability of spinal cord neurons, evoked by electrical stimulation of afferent C-fibers. Different kinds of wind-up have been reported, but wind-up of Abeta fibers in hyperalgesic states has gained little attention. In this paper, we present a cybernetic view on Abeta fiber wind-up and consider the involved molecular...
متن کاملWnt Down, Tumors Wind Up?
In mouse intestinal tumors induced by the inhibition of APC, the restoration of APC function causes complete tumor regression with normal differentiation and return of stem cell function irrespective of whether tumors also carried mutations in Kras and p53. These findings by Dow et al. validate the Wnt pathway as an exquisite target for intervention.
متن کاملDesign of a PI controller with Anti-reset wind up for a Wind Tunnel
Wind tunnel is a test facility used to simulate the flight conditions. It allows us to make a reusable prototype and test it in the tunnel in low cost. Hypersonic wind tunnels operate at hypersonic speeds ie, with a mach number greater than 6. For doing experiments, it is necessary to maintain a constant pressure in the settling chamber of the tunnel so that we get the desired mach number and m...
متن کاملScheduling Imprecise Computations with Wind-up Parts
The imprecise computation model provides the ability to cope with unpredictable workloads. However, there is no consistent way on how to terminate the computation in its early stage. This paper describes a novel approach for safely terminating imprecise computations. First, a new logical part called wind-up part is added to the imprecise computation model. This wind-up part is used by applicati...
متن کاملVirtual Wind-up Toys for Animation
We propose a new method of automatically finding periodic modes of locomotion for arbitrary articulated figures. Cyclic pose control graphs are used as our control representation. These specifically constrain the controller synthesis process to only those controllers producing periodic driving functions. It is shown that stochastic generate-and-test techniques work well with this representation...
