We present a study of certain singular one-parameter subfamilies of Calabi-Yau threefolds realized as anticanonical hypersurfaces or complete intersections in toric varieties. Our attention to these families is motivated by the Doran-Morgan classification of variations of Hodge structure which can underlie families of Calabi-Yau threefolds with h 2,1 = 1(More)
We investigate the seven exceptional families as defined in [GMT]. Experimental as well as rigorous evidence suggests that to each family corresponds exactly one manifold. A certain two generator subgroup in PSL(2, C) is specified for each of the seven families in [GMT]. Using Newton's method for finding roots of polynomials in several variables we solve(More)
An assessment of whether valid EEG data could be collected on helicopter pilots in flight was conducted. Each subject provided eyes-open/eyes-closed EEG in the laboratory and in a helicopter. During flights, EEG's were monitored on the ground in real-time via radio telemetry. Analyses were conducted on the data recorded from Fz, Cz, Pz, P3, P4, O1, and O2(More)
The purpose of this study was to examine the effects of myopia-inducing and myopia recovery conditions on the scleral biomechanics of enucleated eyes of young chicks. Enucleated eyes from 5-day old chicks, with fiducial markers attached at 5 locations on the external sclera, were placed in a custom-built chamber filled with phosphate-buffered saline, and(More)
