  1. NP_Patent number of patents, PII_Patent Patent Impact Index, NP_Paper number of papers, PII_Paper Paper Impact Index
  2. aWeights are calculated using Tables 6 and 7. The specific calculation is as follow: \(\left( {\begin{array}{*{20}c} {0.924} & { - 0.139} \\ {0.740} & {0.232} \\ {0.817} & { - 0.359} \\ {0.275} & {0.909} \\ \end{array} } \right)\left( {\begin{array}{*{20}c} {2.145} \\ {1.208} \\ \end{array} } \right) = \left( {\begin{array}{*{20}c} {1.838} \\ {1.826} \\ {1.384} \\ {1.524} \\ \end{array} } \right)\)
