T-index (h-mixed synthetic index)
The T-index (Ye 2010) is an h-mixed synthetic index which combines multiple metrics together into a single value. It is calculated as
$$T=100\log_{10}\left(R\times h \times C/P\right),$$where R is the R-index and C/P is the mean number of citations per publication.
