Traveling Waves In Biological Population Models, Ahlam Alzahrani Dec 2024

Traveling Waves In Biological Population Models, Ahlam Alzahrani

Theses and Dissertations

In this thesis, we examine the existence of traveling waves in population models. We begin by exploring conditions under which traveling waves exist, even when the migration probability lacks a density function or, if the density function exists, it may be discontinuous. To address this, we impose certain conditions that ensure the monotonicity of the evolution operator, enabling the application of the Monotone Iteration Method. Next, we explore the existence of monotone traveling waves in a general class of integral-difference population models that depend on both the previous state and long-term memory, allowing for the consideration of multiple past states. …

Developing A New Liquefaction Ejecta Prediction Model Considering Soil Properties Of Non-Liquifiable Surface Layers Using New Large Database From The 2012 Emilia Romagna, Italy Earthquakes, Jonah Bradley Dundas

Theses and Dissertations

The presence of a non-liquefied crust overlying a liquefied layer has been found to have a significant effect on sand ejecta and surficial liquefaction damage, as observed by Ishihara (1985). Following the 2010-2011 Canterbury seismic sequence in New Zealand, almost no foundation deformation occurred in areas with liquefaction susceptible soils overlain by at least a 3 meter thick crust [1]. In contrast, the 2012 Emilia-Romagna earthquake in Italy provided surface evidence of liquefaction despite 6+ meter thick crusts. Several researchers have proposed liquefaction prediction models [e.g. LPI [2], Ishihara Curves [3], LSN [4], LPIISH [5] and the methods proposed by …

Mammalian Trait Evolution: Macroevolutionary And Comparative Genomic Analyses Of Diet And Ursid-Specific Adaptations, Matthew David Pollard Dec 2024

Mammalian Trait Evolution: Macroevolutionary And Comparative Genomic Analyses Of Diet And Ursid-Specific Adaptations, Matthew David Pollard

Electronic Theses and Dissertations Archive

Complex traits such as diet have shaped the evolutionary success of species, driving the diversity of form and function that we observe across the tree of life. My research investigates the genomic and macroevolutionary forces behind diet and other complex traits, revealing how they mediate evolutionary change across Mammalia. I utilized two complementary approaches for understanding the evolution of diet in mammals. First, I created two continuous dietary variables—degree of carnivory and degree of dietary specialization—to quantify the impact of diet on mammalian speciation. I found that degree of carnivory, rather than dietary specialization, significantly influenced speciation, but did not …

Machine-Learning And Game-Theoretic Inspired Strategies For Adversarial Freeze-Tag, Matthew Giacovelli Dec 2024

Machine-Learning And Game-Theoretic Inspired Strategies For Adversarial Freeze-Tag, Matthew Giacovelli

Theses

In this thesis, we explore three machine-learning and game-theoretic inspired strategies to address the Freeze-Tag Problem with adversarial agents (FTPA). We develop a custom Gymnasium envi- ronment where unfrozen robots collaborate to “tag” and unfreeze immobile frozen robots while avoiding being tagged by the adversaries. The FTPA models scenarios such as restoring disabled relay towers after a cyberattack where different towers vary in priority, repair difficulty, and ad- versarial threats. We evaluate three strategies: a baseline heuristic where unfrozen robots target the nearest untargeted frozen robot, a hierarchical approach that incorporates adversary interac- tions and likelihood of success into decision-making, …

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John Dec 2024

The Activity And Origin Of The Chitinases In The Gut Of The Mediterranean House Gecko, Alec John

Masters Theses (Archived)

Chitin is a major component of the exoskeleton of arthropods as well as the cell wall of fungi. This amino polysaccharide polymer provides structure and protection to these organisms and represents a significant barrier to digestion of arthropod prey and fighting fungal infections. Chitinases are enzymes that break down chitin. Smaller insectivores, based upon the higher surface-to-volume ratio of their even smaller prey, ingest a large amount of chitin per unit prey item. Therefore, they represent high-likelihood opportunities to bio prospect for novel chitinases that may be effective against pathogenic fungi. Fungal infections are notoriously difficult to treat, and they …

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski Dec 2024

Pmp2+ Scs Maintain The Survival And Functioning Of Large-Caliber Motor Axons, Mikolaj Kozlowski

Arts & Sciences Graduate Student Theses and Dissertations

Neurodegenerative diseases are characterized by selective neuronal vulnerability, a phenomenon in which a specific pathology induces the death of a particular subpopulation of neurons. For example, selective neuronal vulnerability in the peripheral nervous system results in sensory, motor, or mixed peripheral neuropathies. While the intrinsic differences between neuronal subtypes cannot fully explain the basis of selective neuronal vulnerability, it is plausible that it partially stems from neuron extrinsic mechanisms such as the malfunction of distinct Schwann cell (SC) subtypes. Recently, we identified an exciting subpopulation of myelinating SCs characterized by the expression of Adamtsl1, Cldn14, and Pmp2 (hereafter referred to …
