Reconstructing Δ14c Production Events Using Tree Rings: Does Tree Physiology Affect Estimates Of Atmospheric Δ14c?, Meagan Rory Walker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cosmic rays and solar energetic particles (SEP) bombard the Earth’s geomagnetic field, posing a threat to satellites, space stations, and human space exploration. These rays and particles also produce radiocarbon (¹⁴C) in Earth’s atmosphere, thus records of past ¹⁴C concentration in the atmosphere may be indicative of past cosmic and solar activity. Rapid increases in the concentration of atmospheric radiocarbon ¹⁴C, (Miyake events) first identified in tree rings, are thought to be a result of solar eruptive activity triggering the release of solar energetic particles, though the precise nature of past events remains unresolved. The first …

On Uncertainty For Ill-Posed Robot Decision Problems, Jared Joseph Beard

Graduate Theses, Dissertations, and Problem Reports (ETD)

As robots adopt more real world responsibilities, they will be expected to solve more complicated problems. In some cases limited prior knowledge will result in unmodelled environmental conditions; in others, multiple users may have competing perspectives on how to frame a decision problem. Many existing frameworks, namely Markov decision processes (MDP) presuppose users have identified a specific problem with models sufficient to solve or learn a problem. If we wish to extend MDPs to novel problems or those heavily dependent on user feedback, autonomous decision makers must be able to identify limitations in how a given problem is framed and …

Investigation Of L-Serine Synthesis And Transport As Stabilizing Feedback Mechanisms Within The Tsetse-Wigglesworthia Symbiosis, Ryan Phillips

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tsetse flies (Glossina morsitans), which are the obligate vectors of Old-World trypanosomes (Trypanosoma spp.) that cause African trypanosomiasis, have a bacteriome that houses the intracellular endosymbiont Wigglesworthia glossinidia. The ancient coevolution of these species has led to the integration of Wigglesworthia metabolism into tsetse physiology and a subsequent reliance on nutrient exchange for maintaining the fitness of both partners. The establishment of this obligate mutualism has facilitated the emergence of feedback mechanisms that stabilize the symbiosis, such as that which involves the exchange of L-serine and B vitamins. The Gammaproteobacteria Wigglesworthia supplement B vitamins lacking …

It's Written All Over Your Face: A Cultural And Gender History Of The Face In The Middle Ages, 1170-1500, Lacey N. Bonar Hull

Graduate Theses, Dissertations, and Problem Reports (ETD)

At a time of vast social and cultural shifts, people living in western Europe from the late twelfth to the late fifteenth centuries developed and employed methods to “read” the faces of others. This practice promoted the interpretation of inner qualities from external appearances, often used to communicate adherence to or deviation from boundaries of gendered behaviors. My project explores medieval understandings concerning this particular feature of the human body, analyzing discourses concerning the face as a site of symbolism for inner character. While scholars have studied understandings of the self and the “Other” during this period, the role of …
