Graduate Theses, Dissertations, and Problem Reports (ETD)

The expression of most lipogenic enzymes is regulated through the effects of dietary polyunsaturated fatty acids on transcription. However, we have observed that the regulation of Glucose-6-phosphate dehydrogenase (G6PD) by polyunsaturated fatty acids occurs through a novel posttranscriptional mechanism. RNA reporter assays were used to map the cis-acting element by measuring the regulation of each RNA reporter construct transfected into primary rat hepatocytes. All RNA reporter constructs were regulated by polyunsaturated fatty acids with the exception of RNA reporter constructs lacking exon 12. Therefore, polyunsaturated fatty acids regulate the constitutive splicing of G6PD mRNA through a cis-acting element located within …

Multispectral Iris Recognition Analysis: Techniques And Evaluation, Christopher K. Boyce Dec 2006

Multispectral Iris Recognition Analysis: Techniques And Evaluation, Christopher K. Boyce

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis explores the benefits of using multispectral iris information acquired using a narrow-band multispectral imaging system. Commercial iris recognition systems typically sense the iridal reflection pertaining to the near-infrared (IR) range of the electromagnetic spectrum. While near-infrared imaging does give a very reasonable image of the iris texture, it only exploits a narrow band of spectral information. By incorporating other wavelength ranges (infrared, red, green, blue) in iris recognition systems, the reflectance and absorbance properties of the iris tissue can be exploited to enhance recognition performance. Furthermore, the impact of eye color on iris matching performance can be determined. …
