The pH of the boiling brine is computed to decrease from an initial value of around 8, with noticeable breaks at pH 6.6 when halite starts to precipitate (concentration factor around 6,500) and pH around 3.7 when calcium chloride forms (concentration factor around 21,000) (Figures 5 and 6).
The overall oxidation rate of the graphene was computed to be time dependent, with reactivity decreasing over time as the ratio of reactive edge sites decreases relative to the number of basal-plane carbon atoms.
The pre-post difference in costs were computed to obtain the increase (or decrease) of costs over time within each of the conditions.
Multivariable logistic regression models were computed to determine the presence and magnitude of the association between low SES and decreased GFR using occupational grade.
Two metrics are computed to quantify performance.
To measure the effect of IL-7 on the Th1/Th2 balance the ratio between IL-4/IFN-γ-3 was computed; this ratio decreased significantly in allergen-challenged CD4+ cells that were treated with IL-7 compared to untreated cells, 30 compared to 15, p < 0.05 (figure 6C).
Power was computed up to 20 Hz.
Relative contribution was computed as the maximal decrease of a domain divided by the total decrease in utility score for that instrument (excluding the decrease of the interaction terms).
To determine which variables (biochemicals) made the largest contribution to the classification, a variable importance measure was computed, termed the mean decrease accuracy (MDA).
Pmax was computed as equal to 0.25 V0.25.
