They later find out that she is a digital clone of Jubilee named Abscissa, who's been tinkering around in Mojo's code.
(B) Polydispersity analysis of the five samples. Peak positions corresponding to the abscissa represent the diameter of microfibrils in each of the samples. (C) Comparisons of cross-sectional area ...
The abscissa values of the join points are called knots. The term "spline" is also used for polynomials (splines with no knots) and piecewise polynomials with more than one discontinuous derivative.
