High-Signal Contrast Source Scan - Biophysical Chemotaxis and Gradient Sensing Step by Step

A fixed low occupancy lets the high-side signal set the contrast fraction. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

High signal twelve leaves one sixth contrast

Low occupancy stays 1/2. High signal 12 gives occupancy 2/3 and contrast 1/6.

\frac{2}{3}-\frac{1}{2}=\frac{1}{6}

High signal eighteen gives one fourth contrast

High signal 18 gives occupancy 3/4 and contrast 1/4.

\frac{3}{4}-\frac{1}{2}=\frac{1}{4}

High signal thirty gives one third contrast

High signal 30 gives occupancy 5/6 and contrast 1/3. The model does not add receptor dynamics.

\frac{5}{6}-\frac{1}{2}=\frac{1}{3}
