Creator:: Stock, Marika P.
Abstract:: Nitrous oxide is an important greenhouse gas that has both natural and anthropogenic sources in the modern atmosphere (Ciais et al., 2013). This project expanded the knowledge of the history of atmospheric N2O in the geologic past by measuring N2O concentrations in air trapped in very old polar ice. A...

Creator:: Gabor, Christian A.
Abstract:: Artificial Intelligence has gained resurgence in popularity through machine learning methods. This thesis investigates the current use of AI, the impact it will have on the economy and the ethical considerations for developing this technology. In the coming decade AI could increase global economic output over $10 Trillion. AI will...

Creator:: Britsch, Melissa L.
Abstract:: Anthropogenically-induced increases in the acidity of the ocean have the potential to seriously harm marine calcifying organisms by decreasing the availability of carbonate (CO32−) used to make shells. I tested the effects of lowered pH on juvenile Pisaster ochraceus, an intertidal sea star and keystone predator in the eastern Pacific...

Creator:: Klein, Victoria G.
Abstract:: Atmospheric carbon dioxide has increased by approximately 40% since preindustrial times from 280 ppm (parts per million) to 400 ppm. The rise in Pco₂ is causing the ocean to become more acidic due to the uptake of carbon dioxide by the water, termed “ocean acidification”. As the Pco₂ in the...

Abstract:: M. avium is an opportunistic pathogen that primarily infects macrophages. In order to survive within the macrophage, M. avium secretes proteins into the host cell cytoplasm to inhibit specific functions such as phagosome acidification, altering pathways as well as initiating apoptosis. However, little is known about how those secreted proteins...

Creator:: Neal, Lawrence W.
Abstract:: Recent work in machine learning concerns the detection and identification of bird species from audio recordings of their vocalizations. Such analysis can yield valuable ecological information concerning the activity and distribution of species in the wild. Current species-identification methods require individual syllables of bird audio as input, but field-collected audio...

Creator:: Biel, Justin T.
Abstract:: The planar peptide model has guided our understanding and interpretation of protein crystal structures since its origin in the 1950s. It is well understood that deviations from this model occur, but the majority of peptides are planar, as measured by the standard omega torsion angle. Here, we report the first...

Creator:: Meier, Emily K.
Abstract:: Anthropogenic CO₂ emissions are shifting the global climate equilibrium, causing widespread losses in biodiversity. Anthozoan cnidarians are some of the species most vulnerable to environmental change. Environmental stress causes corals and sea anemones to expel their endosymbiotic algae, which constitute a primary source of nutrition for some Anthozoa. Carbonic anhydrase...
