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

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

Journal of Forestry ResearchAbstract Timber quality modeling is essential for value-oriented forest management since the traditional, volume-only yield models often ignore internal defects (notably knots) and overestimate usable wood. In this study, we developed an integrated framework to quantify knot-free and knotty core volumes in Korean ...

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.

Resonances:tuning into the echoes of the ecological collective [PDF]
, 2020 Drawing on posthumanist and new materialism theorising, we take the concept of resonance for an a/r/tographic 'walk' to know, be and do differently, to challenge human-centric separatist ways that have resulted in our current socioecological crises ...
