Because we used response surface methodology, there was no need to double the quadratic coefficients [ 34].
Their structure enhances Li+ intercalation into the oxide matrix, thus doubling the diffusion coefficient.
For example, increasing the flow rate from 4.4 to 34 ml min−1 doubled the sonication coefficient for bromobenzene in a mixture, possibly due to better temperature control and mixing.
The results indicated that ShhN almost doubled the colocalization coefficient between Ptch1-GFP and endogenous Cav-1 from 0.37 ± 0.04 to 0.68 ± 0.04.
Making the described adjustment for hepatic fat gave SUVmean a stronger correlation with Ki/V 0) compared with the corresponding unadjusted values (approximately doubling the correlation coefficients for both SUWmean and SULmean; Table 1).
This feature has two advantages: it eliminates the longitudinal temperature increase (flow thermal resistance) that would occur in fully developed laminar flow, and it doubles the heat transfer coefficient associated with fully developed laminar flow.
However, removing Connecticut and Massachusetts almost doubled the meta-regression coefficient for the PM2.5 PM10 ratio and nullified the association for median PM2.5 exposure levels, and the meta-regression estimate for median PM2.5 exposure levels was null after New Jersey was excluded.
The correction for regression dilution approximately doubled the standardised β coefficients.
We doubled the quadratic regression coefficients to obtain quadratic selection differentials [ 66, 67].
