Fig. 2.

For chosen values of $a=-0.4$, $c_0=2$, $c_1=4$, we show time (arbitrary units) on the horizontal axis and the dependent (dep.) variables on the vertical axis—consisting of the time course of $x\left(t\right)$ (solid black line), the corresponding mirror time course $\tilde{x}\left(t\right)$ (dashed line) from Eq. (6), and the resultant constant energy $E$ (red line) time course from Eq. (7)
