Selected features, as reported on Table 2, resulted to be: (1) contrast, (2) cluster shade, (3) energy, (4) entropy, (5) homogeneity, (6) information measures of correlation and (7) inverse difference moment.
Previous studies recognized that Contrast represented the amount of local gray level variation, Correlation represented the linear dependency of grey levels of neighboring pixels, Energy represented image homogeneity, Entropy represented the amount of information of the image that is needed for the image compression, and IDM represented the local homogeneity [12].
Data for indicators were obtained from national public databases, otherwise the homogeneity of information cannot be guaranteed as there are differences between statistics services in the regions.
The E-I (external internal) index technique was used to examine the degree of homogeneity of information sharing and the adopters' group affiliation.
Location of the nodes (actors) are random (3) The E-I (external internal) index technique was used to examine the degree of homogeneity of information sharing and the adopters' group affiliation.
The recombinantly produced variants were purified to homogeneity (supporting information, Fig. S1), and their stabilities and functions were determined.
Proteins were purified to near homogeneity (Supporting Information, Figure S1).
All MftR protein variants were purified to apparent homogeneity (Supporting Information, Figure S1A).
The MecI protein was expressed and purified to homogeneity (Supporting Information).
To confirm our genetic observations, we overexpressed ybaS and yneH in E. coli, and biochemically purified the two recombinant proteins to homogeneity (Supplementary information, Figure S4).
