Knotty-centrality: finding the connective core of a complex network. [PDF]

PLoS ONE, 2012
A network measure called knotty-centrality is defined that quantifies the extent to which a given subset of a graph's nodes constitutes a densely intra-connected topologically central connective core. Using this measure, the knotty centre of a network is

Erratum to: Effects of pruning on knotty core taper and form of Pinus radiata and Pinus pinaster [PDF]

European Journal of Wood and Wood Products, 2016
Due to an error during conversion of Geographic Units (Latitude, Longitude) from UTM coordinates, information given for location of the experimental plots in Table 1 of the manuscript is not correct. The data of location of the plots should be replaced by: Site Index has been recalculated at the time of establishment of the pruning plots.

Nonthermal X-ray emission from 3C 273 - The core of a knotty problem?

The Astrophysical Journal, 1990
The quasar 3C 273 was observed in the hard X-ray region of the spectrum (15-300 keV) during a stratospheric balloon flight on July 15, 1987. The emitted photon spectrum is well described by a single power law of photon index -1.61 which corresponds to a hard (20-200 keV) X-ray luminosity of 0.8 x 10 to the 47th ergs/s.
