Renault Twingo Renault Twingo The Renault Twingo is a four passenger city car manufactured and marketed by the French automaker Renault, introduced in 1992 and currently in its third generation. The first generation Twingo (two door, front engine) debuted at the Paris Motor Show on 5 October 1992, receiving its formal market launch in continental European markets beginning in April 1993. Renault launched the second-generation Twingo (two door, front engine) in the summer of 2007 — and the third generation (four door, rear engine) debuted at the 2014 Geneva Motor Show, receiving its formal market launch in September 2014.

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
