The relationship of sinusoidal smooth pursuit defects to pursuit defects with step-ramp targets in patients with cerebral lesions is unclear. We examined pursuit and saccades to both step-ramp and sinusoidal targets in 17 patients with unilateral cerebral lesions. Two types of pursuit defects were found. One group of three patients had ipsi-directional sinusoidal pursuit defects from lesions to...

The directional relationship of spatial objects is an important spatial relationship of GIS, which is involved in spatial database query, spatial position, and spatial analysis etc. The directional relations in GIS are most commonly represented with qualitative representation model and quantitative representation model. The quantitative models represent direction relationships by angle (quadran...

The last major reversal of the Earth’s magnetic field, the Matuyama–Brunhes boundary (MBB), dated at 0.78Ma, is widely identified in Australian and New Zealand Pleistocene deposits. In New Zealand, the MBB is precisely located in shallow marine sediments of Wanganui Basin, where it corresponds with the base of the New Zealand Putikian Substage. A combination of marine biostratigraphy, sequence ...
