Cortical and tectal inputs to the caudal LPN in the rat were examined using anatomical and physiological techniques. Pyramidal cells in layer 6 of the visual cortex and wide-field vertical cells in the stratum opticum of the superior colliculus...
In the retina, the receptive fields (RFs) of most neurons are comprised of an excitatory center and a suppressive surround. Retinal ganglion cell (RGC) RF center excitatory input arises from bipolar cell (BC) inputs, while their surround arises...
The pulvinar is the largest nucleus of the human dorsal thalamus and is affected in a variety of brain disorders, such as schizophrenia. The experiments described in this dissertation elucidate key features of tecto-pulvino-cortical pathways as a...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....
College dropouts; Dropout behavior, Prediction of; Prediction of scholastic success
The persistence of second-year college students is gaining attention nationally. Vast resources have been dedicated to the retention of first-year students only to lose them at some point during the second year. Much of the research about the...
Pattern perception--Data processing; Pattern recognition systems; Land mines--Detection; Data mining
For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing...
Pattern recognition systems; Land mines--Detection; Pattern perception--Data processing; Data mining
Traditional machine learning and pattern recognition systems use a feature descriptor to describe the sensor data and a particular classifier (also called "expert" or "learner") to determine the true class of a given pattern....
This thesis is an examination of the viability of a low pH hydrogen peroxide scrubbing process for removing H 2 S acid gas present in typical biogas streams generated from dairy farm anaerobic digesters. Biogas ranges in composition based on the...
Medical appointments and schedules; Simulation methods
Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
