Theses and Dissertations

Human papillomavirus (HPV) is the etiologic agent for cervical cancer with HPV type 16 (HPV16) being found in about 50% of cervical cancers worldwide. HPVs vary in genomic (DNA) sequence not only between types, but also within types, known as variants. Variants of a particular HPV type may differ by up to 2% in nucleotide sequence in the coding region and up to 5% in the noncoding region. Variants within HPV16 have been identified and grouped into six distinct phylogenetic branches, which segregate geographically: European (E), Asian-American (As.A), African-1 (Af-1), African-2 (Af- 2), Asian (As), and North American (NA). However, …

Assessing The Competitive Advantage Of Carbonic Anhydrase In Estuarine Microalgae Through Removed Enzymatic Activity, Eilea R. Knotts

Theses and Dissertations

Carbon concentrating mechanisms (CCMs) are used by photoautotrophs to overcome possible limitations in carbon acquisition but the competitive strategies and efficiencies of these mechanisms among photosynthesizers can be variable. The diversity in carbon acquisition abilities establishes the potential for alterations in community structure with shifting carbon concentrations. Given the role of phytoplankton and benthic microalgae (BMA) in the trophodynamics of estuaries, understanding the mechanisms of carbon acquisition in these systems is important in predicting how primary productivity and nutrient cycling might change in response to increasing concentrations of atmospheric CO2. Our approach to investigate whether induced carbon limitation would show …

Discovery Of Materials Through Applied Machine Learning, Travis Williams

Theses and Dissertations

Advances in artificial intelligence technology, specifically machine learning, have cre- ated opportunities in the material sciences to accelerate material discovery and gain fundamental understanding of the interaction between certain the constituent ele- ments of a material and the properties expressed by that material. Application of machine learning to experimental materials discovery is slow due to the monetary and temporal cost of experimental data, but parallel techniques such as continuous com- positional gradients or high-throughput characterization setups are capable of gener- ating larger amounts of data than the typical experimental process, and therefore are suitable for combination with machine learning.
