Description:
 def nhill_i(self,x,threshold=0.1,power=2):
 """ Normalized inhibiting hill function. Is equivalent to 1-nhill_a(self,x,power,threshold). """

        x_pow = np.power(x,power)
        threshold_pow = np.power(threshold,power)
        return threshold_pow / (x_pow + threshold_pow) * (1 - x_pow)
