| To estimate the construct validity, we used correlation analysis to check the isotonicity among the inputs and outputs. |
| With time, as osmotic gradients are building up, the apparent stoichiometry tends to increase toward isotonicity. |
| Once the solid material had been dissolved there could be a bit of adjustment to get the solution toward isotonicity. |
| We used this convenient notation for simplicity, keeping in mind that this notation slightly overestimated the tonicity difference from isotonicity. |
