The Department of Homeland Security (DHS) and the United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is preparing to transition from a two print capture process to a 10-print slap capture process. In preparing for the 10-print pilot testing, a concern that the existing counters that house the fingerprint scanners are too tall(More)
We describe the development of a computer-generated arena within which one can study human place learning by asking subjects to locate an invisible target. A series of studies demonstrate that such learning is based on acquiring knowledge about the spatial relations among the distal cues presented in this arena. We show that (1) the presence of proximal(More)
Data quality limits the accuracy of biometrics. Poor data quality is responsible for many or even most matching errors in biometric systems and may be the greatest weakness of some implementations. This paper uses an expansive view of data quality focused on its implications for operational databases and systems. Data quality is defined here not just in(More)
We compared five indices of brain structure between two groups of schizophrenics, namely, those with high and normal levels of antibody in the serum to herpes virus. Eleven 'immuno-positive' and 21 'immuno-normal' subjects obtained from a concomitant study of serum IgG antibody to viruses underwent magnetic resonance imaging (MRI) utilizing a 1 Tesla magnet(More)
Intracranial, dural-based neoplasms will not infrequently invade adjacent venous sinuses. Therefore, the preoperative diagnosis of venous invasion is important, as it will alter the surgical approach to the lesion. Magnetic resonance imaging is a noninvasive means of visualizing the cerebral venous sinuses. The preoperative diagnosis of venous thrombosis(More)
