[Differentiation of the neural crest. Influence of growth factors].

Annales d'endocrinologie, 1989
The peripheral nervous system (PNS) is derived from a transitory embryonic structure, the neural crest with an additional contribution of the cephalic ectodermal placodes to the sensory ganglia of certain cranial nerves. In vivo grafting experiments, taking advantage of the quail/chick marker system, allowed the fate map of the neural crest to be ...

Crest factor minimization: A neural network approach

1996
Summary: The crest factor (CF) of a signal is defined as the ratio of its peak value and its root mean-squared value. A state-space model is proposed for the minimization problem of the crest factor in the case of a multisine signal.This state-space model provides a stable neural network and it can be studied using computer simulation.
