Renault Fluence metallic). It can accelerate from 0-100 km/h (62 mph) in 8 seconds and top speed is limited to . In 2004, Renault presented a 2+2 concept coupé, named Fluence and designed by then Renault chief designer Patrick le Quément, with a length similar to that of the Renault Laguna. It was shown on June 4, 2004, at the "Louis Vuitton Car Elegance Classic" in England, and at the Mondial de l'Automobile 2004. The Fluence uses Valeo LED headlights that are angled according to the steering wheel position. An ingenious aspect of the Fluence's exterior design is its V shaped rear
Quantitative models of the action potential that again, there are only two time-dependent variables: the transmembrane voltage "V" and the potassium gate probability "n". The bursting, entrainment and other mathematical properties of this model have been studied in detail. The simplest models of the action potential are the "flush and fill" models (also called "integrate-and-fire" models), in which the input signal is summed (the "fill" phase) until it reaches a threshold, firing a pulse and resetting the summation to zero (the "flush" phase). All of these models are capable of exhibiting entrainment, which is commonly observed in nervous systems. Whereas the above models simulate the transmembrane
