The medial surface areas of the cingulate gyrus (CG) and other midline structures (corpus callosum, thalamus, lateral ventricle) were examined in 27 traumatically brain injured (TBI) and 12 age- and gender-matched control subjects from an established TBI data base. Significant atrophy, primarily in the posterior CG, was found in TBI patients. Degree of(More)
The natural reproductive ecology of freshwater eels remained a mystery even after some of their offshore spawning areas were discovered approximately 100 years ago. In this study, we investigate the spawning ecology of freshwater eels for the first time using collections of eggs, larvae and spawning-condition adults of two species in their shared spawning(More)
Of more than 800 species of eels of the order Anguilliformes, only freshwater eels (genus Anguilla with 16 species plus three subspecies) spend most of their lives in freshwater during their catadromous life cycle. Nevertheless, because their spawning areas are located offshore in the open ocean, they migrate back to their specific breeding places in the(More)
There are several magnetic resonance (MR) imaging methods to measure brain volume and cerebral atrophy; however, the best measure for examining potential relationships between such measures and neuropsychological performance has not been established. Relationships between seven measures of MR derived brain volume or indices of atrophy and neuropsychological(More)
In this paper, we present the modeling and estimation aspects of a virtual reality system for plastic and reconstructive breast surgery. Our system has two modes, a model creation mode and a model tting mode. The model creation mode allows a surgeon to interactively adjust the shape of a virtual breast by v arying key shape variables, analogous to the(More)
We examined asymmetry of hippocampal volume as well as other temporal lobe structures (temporal lobe, temporal horn of the lateral ventricular system, parahippocampal and fusiform gyri) in 194 subjects from the Cache County, Utah study, with varying disorders [85 with Alzheimer's disease (AD), 59 with some cognitive or neuropsychiatric disorder-referenced(More)
With the dawn of 3D printing technology, patient-specific implant designs are set to have a paradigm shift. A topology optimization method in designing patient-specific craniofacial implants has been developed to ensure adequate load transfer mechanism and restore the form and function of the mid-face. Patient-specific finite element models are used to(More)
Reason-based actions plunge the reasoner into temporal considerations from all angles. We see this not only when time enters explicitly into the problem statement, but also in formal robot blocks-world scenarios, in the Yale Shooting Problem and other associated versions of the frame problem (e.g., [Hanks and McDermott, 1986]), in various specialized(More)
Multiple variables were examined in relation to outcome of ECT in a complete population of 261 patients treated over a four-year period. Sixty-three percent were rated as much improved. Response to ECT was not predicted by identifying data, DSM-III Axes I, II and III, Research Diagnostic Categories (RDC) or the majority of the "blind" clinical ratings and(More)
