Optical coherence tomography for the non-invasive investigation of the microstructure of ancient Egyptian faience [PDF]
, 2012 Optical Coherence Tomography (OCT) is a non-invasive subsurface 3D imaging technique based on the Michelson interferometer. The non-invasive nature of OCT and its speed of acquisition makes it possible to image large volumes of intact objects to yield a ...

Impact scores of invasive plants are biased by disregard of environmental co-variation and non-linearity [PDF]
, 2011 Prioritisation of high-impact species is becoming increasingly important for management of introduced species (‘neobiota’) because of their growing number of which, however, only a small fraction has substantial impacts.
