Chemical modifications of the carbon surface have been applied in previous hydrophilization techniques, whereas alternative hydrophilization pathway free from the surface modifications is expected to give considerable advantage because the obtained carbons keep inherent surface properties.
These methods have been applied in previous publications on cross-reactivity of drug of abuse and therapeutic drug monitoring immunoassays [44, 47 49].
To perform hand contour detection, some classical preprocessing methods have been applied in previous works [3, 4, 10, 13]: the YC b C r mapping and the selection of the C r component emphasize the hand surface with respect to the background.
This approach has been applied in previous studies [27], [34].
Nonetheless, a similar method of analysis to ours has been applied in previous studies and provides an indicator of some of the elements of the variation in cephalothorax color e.g. [60].
The GoM method has been applied in previous studies for depressive symptoms and personality disorders [2], [3], [4], older adult health status [5], [6], [7], [8], [9] and genetic health studies [10], [11].
The design parameter 'V' that was applied in previous studies was slightly modified for the purpose of the current research.
As sensitivity analysis, we correlated the RF interrelations of the full-information networks with the RF interrelations of the complete-information networks (N CA = 508; N no-CA = 443), which are based on listwise case deletion (which was applied in previous research, see for example66).
This approach was applied in previous studies [ 35- 37].
Mutual information was applied in previous studies [ 20, 45, 46].
A similar research protocol was applied in previous research [ 6, 18, 19].
