Renault Fluence Mégane range featured a "three box" notchback sedan variant until 2008, but this was never a big seller and when, at the end of that year, the Mégane III was introduced, there was no notchback version available. It is the gap in the range left by the removal of this model from the FrancoSpanish assembled Mégane range that the Fluence fills in those markets in the company's western European heartland, such as France, Italy, Belgium, Ireland and, since August 2010, Germany, where Renault offers it. The Renault Fluence is also badged as Renault Samsung SM3. The Renault Samsung car was
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
