Brain tumors account for ~2% of all cancers, with gliomas accounting for ~70% of all brain tumors. Evidence suggests that extent of resection provides both a quality of life and survival benefit to patients. Recent work has shown the utility of...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
A metric structure on a set gives a concept of distance between any two elements of that set, and it induces a topology. In this thesis, we provide several ways to put a metric structure on the collection of CW complexes. We accomplish this by...
In this thesis we look at several problems that lie in the intersection between combinatorial and multiplicative number theory. A common theme of many of these problems are estimates for and properties of the smooth numbers, those integers not...
This thesis contains material relating to two separate subjects. The first section determines when the C*-algebra affiliated to a directed graph has continuous trace. We use groupoid methods and the focus is on producing conditions on a graph that...
Multiresolution image transformations have become commonplace tools for analyzing images for a number of applications, including enhancement and restoration. Powerful models for these applications have been developed in the transform domain of...
In the Firefighter Problem, a fire starts at a vertex of a graph, and in discrete time units, it spreads from burned vertices to their neighbors, unless they are protected by one of the f firefighters that are deployed every turn. Once burned or...
Face perception -- Physiological aspects. Face perception -- Social aspects. Sex differences (Psychology). Neuropsychology.
The general objective of the current thesis was to investigate the neural substrates underlying the perception of opposite-sex faces. Building on what is already known about the distributed network of brain areas supporting various dimensions of...
Sensing light from the environment using photoreceptors is of great adaptive significance to eukaryotes. A prominent feature of the photochemistry of these receptors is the photocycle length, the time taken to decay from the initial signaling light...
PDZ domains are protein:protein interaction domains that serve as molecular scaffolds, especially in the case of specialized cellular environments like polarized airway epithelial cells of the human lung. Historically the domains have been thought...
Developmental prosopagnosia (DP) is a neurodevelopmental disorder defined by impaired face recognition in the absence of brain damage, low-level visual deficits, or broad cognitive problems. Behavioral and neural findings suggest different types of...
The neurophysiological examination of auditory-object representations has focused on how early auditory cortical areas code for the spectral and temporal features of auditory objects. The goals of this dissertation was to investigate how auditory...
Brain -- Localization of functions. Analogy. Frontal lobes. Neuropsychology.
This thesis represents a program of behavioral and brain-based research directed at elucidating the mechanisms of analogical reasoning. The studies that comprise this thesis took convergent experimental approaches to extend knowledge concerning two...
Hand -- Psychophysiology. Conditioned response. Hand -- Movements. Perceptual-motor processes.
The present studies examine the flexible application of two stimulus-response (SR) mappings to a single set of stimuli. The following questions are addressed: (1) Can dual mapping performance equal single mapping performance (2) Can rapid map...
