We analyse 400 ks of XMM-Newton data on the active galactic nucleus NGC 1365 using principal component analysis (PCA) to identify model independent spectral components. We find two significant components and demonstrate that they are qualitatively different from those found in MCG–6-30-15 using the same method. As the variability in NGC 1365 is known to be due to changes in the parameters of a ...

OBJECTIVE To validate the use of three-dimensional (3-D) surface rendering (SR) images to quantify the height of alveolar dehiscences. MATERIALS AND METHODS Twenty-four dehiscences were created on 9 incisors, 9 canines, and 6 premolars on 4 cadaver skulls. i-CAT cone beam computed tomography scans (CBCTs) were taken of each skull at .2 mm voxel size. Each dehiscence was quantified by 21 ortho...
