Renault Fluence Z.E. in the market and the first of South Korean assembly, the SM3 Z.E. led electric vehicle sales in the country, capturing a 58% market share of the segment and 453 cars sold that year. The company attributed this to its AC-3 charger, its greater autonomy compared to rivals and a better warranty for the battery. The Fluence Z.E. was released in the United Kingdom in the Spring of 2012 though was withdrawn from sale in 2014. The batteries required a mandatory lease which according to Renault, was the UK's most affordable electric car. By not having to purchase the battery
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
