Which physician assessment index: H, G or R?

An empirical investigation of the g-index for 26 physicists in comparison with the h-index, the A-index, and the R-index

J.E. Hirsch (2005) introduced the h-index to quantify an individual’s scientific research output by the largest number h of a scientist’s papers that received at least h citations. To take into account the highly skewed frequency distribution of citations, L. Egghe (2006a) proposed the g-index as an improvement of the h-index. I have worked out 26 practical cases of physicists from the Institut...

Physician performance assessment using a composite quality index.

Assessing physician performance is important for the purposes of measuring and improving quality of service and reducing healthcare delivery costs. In recent years, physician performance scorecards have been used to provide feedback on individual measures; however, one key challenge is how to develop a composite quality index that combines multiple measures for overall physician performance eva...

Minimal hypersurfaces in H × R, total curvature and index

In this paper, we consider minimal hypersurfaces in the product space Hn × R. We begin by studying examples of rotation hypersurfaces and hypersurfaces invariant under hyperbolic translations. We then consider minimal hypersurfaces with finite total curvature. This assumption implies that the corresponding curvature goes to zero uniformly at infinity. We show that surfaces with finite total int...
