Figure 8
A line graph titled FSign vs Cai. The horizontal axis is labeled Cai ranging from 0.0 to 1.0. The vertical axis is labeled FSign ranging from -5 to 0. The graph features two lines: a red line representing FSign and a blue line representing a constant value at 0. The red line starts at 0, dips sharply to around -5 at approximately 0.2 Cai, rises to a peak slightly above 0 at around 0.4 Cai, dips again to around -3 at approximately 0.6 Cai, and then rises back to 0 at around 0.8 Cai before dropping sharply again.as a function of with , and
