Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

Mahler's order functions and algebraic approximation of p-adic numbers

Creator:: Dietel, Brian Christopher
Abstract:: If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

Stags of the Sea or Hedgehogs of the Harbor? Inferring the Point of Sculpin Cranial Weaponry

Creator:: Buser, Thaddaeus J.
Abstract:: Animal weapons are thought to have evolved to compete for reproductive opportunities within a species. Across the diverse weapon-bearing taxa, several evolutionary trends have emerged: (1) increasing complexity and relative size across ontogeny, (2) sexual dimorphism, and (3) higher levels of random deviations from symmetry (i.e., fluctuating asymmetry) than non-weaponized...

Crossing Boundaries during Stress Responses: Antigen Presentation by Adaptive and Innate MHC Class I Molecules

Creator:: Nagamine, Brandy S.
Abstract:: The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...

Non-Canonical Nedd8 Conjugation Mediated Targeted Protein Degradation and Direct Antigen Presentation

Creator:: Vijayasimha, Kartikeya
Abstract:: While the role of ubiquitin in protein degradation is well established, the role of other ubiquitin-like proteins (UBLs) in protein degradation is less clear. Neural precursor cell expressed developmentally down-regulated protein 8 (NEDD8) is the UBL with the highest level of amino acid identity when compared to ubiquitin. Here we...

Steady-State Diffusion in a Spatially Varying Porous Medium

Creator:: Ferrero, Peter T.
Abstract:: Heterogeneous porous material represents a persistent challenge in the field of engineering. Microscale properties such as the porosity and microchannel torturosity significantly control the macroscale transport characteristics of homogeneous porous medium. Additional complexity is introduced when these small-scale features vary in space. Examples of heterogeneous porous systems include artificial body...

Investigation into the role of strength and toughness in composite materials with an angled incident crack

Creator:: Grimm, Brian A.
Abstract:: Understanding the mechanical behavior of composite materials requires extensive knowledge of fracture behavior as a crack approaches an interface between the bulk material and the reinforcement structure. Overall material toughness can be greatly influenced by the propensity of an impinging crack to propagate directly through the substrate or deflect along...

Adversarial planning by strategy switching in a real-time strategy game

Creator:: King, Brian D.
Abstract:: We consider the problem of strategic adversarial planning in a Real-Time Strategy (RTS) game. Strategic adversarial planning is the generation of a network of high-level tasks to satisfy goals while anticipating an adversary's actions. In this thesis we describe an abstract state and action space used for planning in an...

A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

Creator:: Kawula, Steven P.
Abstract:: Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...
