Existence Of Traveling Waves In A Predator-Prey Invasion Model With Nonlocal Dispersal And Delayed Effects In Dispersal, Austin Simms

Theses and Dissertations

We investigate the existence and stability of traveling wave solutions in a predator--prey population model that incorporates both nonlocal dispersal and time-delayed interactions. The problem arises when species distributions and feeding or reproduction processes do not respond instantaneously, but rather exhibit lags in space and time. Our aim is to understand how these delays and nonlocal effects impact the wavefront speed and the eventual establishment of a predator population in previously prey-dominated regions. To accomplish this, we derive a PDE--integro--delay system from ecological considerations of prey self-regulation, predator ratio dependence, and jump-type dispersal kernels. We then employ a traveling wave …

Linking Geographic Distribution And Niche Through Estimation Of Niche Density, Tad Dallas, Cleber Ten Caten

Faculty Publications

1. The availability of suitable niche space constrains where species can occur geographically. This tie between niche space and geographic space is crucial when estimating species geographic distributions in a changing climate. However, specific combinations of climatic conditions may be overrepresented in geographic space, highlighting the potential disconnect between climatic niche area and geographic range size.
2. We develop a niche density estimator that accounts for the geographic availability of climatic niche space, relate this to traditional estimates of niche area and explore how these niche estimates are related to species geographic range size.
3. To do this, we use data on over …

The therapeutic landscape in ALL has changed dramatically over the last decade. Allogeneic blood or marrow transplantation (AlloBMT) has also evolved and remains an important option for consolidation. We assessed the interplay between these factors by analyzing the outcomes of 251 adult ALL (214 B and 37 T ALL) patients undergoing alloBMT with post-transplantation cyclophosphamide (PTCy) across two eras: 2008-2014 (ERA1) and 2015-2022 (ERA2). ERA1 patients were younger (median age 45.5 vs. 50, p=0.03), less likely to have an HCT-CI ≥4 (9% vs. 21%, p=0.01), more likely to have MRD by flow cytometry (20% vs. 9%, p=0.01) and receive myeloablative …

Human Genetic Variation Determines 24-Hour Rhythmic Gene Expression And Disease Risk, Ying Chen, Panpan Liu, Aniko Sabo, Dongyin Guan

Faculty, Staff and Students Publications

24-hour biological rhythms are essential to maintain physiological homeostasis. Disruption of these rhythms increases the risks of multiple diseases. Biological rhythms are known to have a genetic basis formed by core clock genes, but how individual genetic variation shapes the oscillating transcriptome and contributes to human chronophysiology and disease risk is largely unknown. Here, we mapped interactions between temporal gene expression and genotype to identify quantitative trait loci (QTLs) contributing to rhythmic gene expression. These newly identified QTLs were termed as rhythmic QTLs (rhyQTLs), which determine previously unappreciated rhythmic genes in human subpopulations with specific genotypes. Functionally, rhyQTLs and their …

Hippocampal-Prefrontal Functional Neural Networks In A Rat Model Of Fragile X Syndrome Are Poorly Organized With Limited Resiliency, Mohamed Ouardouz, Patrick Jasinski, Mohamed Khalife, J. Matthew Mahoney, Amanda E. Hernan, Rod C. Scott

Department of Neurology Faculty Papers

Fragile X Syndrome (FXS) is a common cause of autism spectrum symptoms. The genetic mutation results in multiple molecular alterations that are hypothesized to negatively impact neural circuit development although the nature of any functional neural dynamic consequences remain unclear. Therefore, the characteristics of hippocampal-prefrontal (H-PFC) network dysfunction were investigated in a rat model of FXS. FMR-KO and control rats underwent behavioral tests assessing sociability, memory, and anxiety to validate and replicate previously recognized deficits. Single-unit electrophysiology in the H-PFC circuit during exploration was used to measure patterns of action potential firing that were then compared between groups using generalized …

Music And Cognition: How To Keep The Brain On Beat, Rylen Sakamoto

Student Scholar Symposium Abstracts and Posters

Music, as the conversion of words and sounds into expressive art, has been often used as a form of catharsis or emotional regulation. While research on common mood outcomes from music exists, further examination is necessary, as this knowledge, once fully understood, can be applied beyond music therapy, and be utilized to enhance our cognitive efficiency. Current research includes Music Mood Theory, which suggests that music has a meaningful impact on our moods, which correlate with behaviors such as maintaining tempo and harmony (Hu, 2010). The purpose of this study was to establish a deeper perspective on the impact music …

T cell activation requires a substantial increase in NAD+ production, often exceeding the capacity of oxidative phosphorylation (OXPHOS). To investigate how T cells adapt to this metabolic challenge, we generate T cell-specific ADP/ATP translocase-2 knockout (Ant2-/-) mice. Loss of Ant2, a crucial protein mediating ADP/ATP exchange between mitochondria and cytoplasm, induces OXPHOS restriction by limiting ATP synthase activity, thereby impeding NAD+ regeneration. Interestingly, Ant2-/- naïve T cells exhibit enhanced activation, proliferation and effector functions compared to wild-type controls. Metabolic profiling reveals that these T cells adopt an activated-like metabolic program with increased mitobiogenesis and anabolism. Lastly, pharmacological inhibition of ANT …

An Analysis Of The Armorettes’ Mission To Help The Atlanta Lgbtq+ Community, Edwin Hernandez

Master's Theses

The Armorettes are a self-proclaimed camp drag troupe that have been performing in the Atlanta drag scene since 1979. First formed as a cheer group for a softball team associated with The Armory, a well known gay bar at the time, they quickly added drag performance and charity work to their name. The group came to be as the HIV/AIDS epidemic began affecting Atlanta. Atlanta was hit hard by the disease. Several comorbid factors contributed to the disproportionate numbers seen in the city beginning in the 1980s. They quickly took on the mission of raising money for charities and organizations …

High-Quality Factor Phase Gradient Metasurfaces With Dynamic Reconfigurability, Lin Lin

Arts & Sciences Graduate Student Theses and Dissertations

Free-space optical communication holds immense potential for surpassing the bandwidth limitations of conventional physically defined channels. Achieving flexible and efficient communication in free space requires compact, robust optical components capable of dynamically tuning laser light without relying on bulky lenses or mechanically driven mirrors. Metasurfaces, or flat optics, have garnered significant attention due to their densely arranged subwavelength nano-resonators, which impart phase, amplitude, and polarization changes comparable to those of traditional bulky optics. However, conventional phase gradient metasurfaces are constrained by passive designs based on geometric configurations and the weak light-matter interaction inherent in most dielectric materials, limiting their applicability …

Induced Cd8a Identifies Enhanced Human Nk Cell Il-15-Induced Proliferation And Metabolism And Modulates Nk Cell Activation, Celia Cubitt

Arts & Sciences Graduate Student Theses and Dissertations

Natural Killer (NK) cells are cytotoxic innate lymphoid cells that play an important role in the surveillance and elimination of virally-infected and malignantly-transformed cells. These primary effector functions are achieved by producing cytokines and chemokines which activate and recruit additional immune effectors, as well as direct cytotoxic killing via perforin and granzymes. NK cell function is tightly regulated by a balance of germ-line encoded activating, inhibitory, co-stimulatory, and cytokine receptors expressed at the cell surface. Through these activating and inhibitory receptors, NK cells recognize and kill targets without prior sensitization through the loss of self-identifying molecules such as major histocompatibility …

Parapinopsin: A Photoswitchable Inhibitory Gpcr For Two-Photon Optogenetics, Bobbie J. Brown

Arts & Sciences Graduate Student Theses and Dissertations

The development of optogenetic tools has greatly advanced the capability of researchers to understand the connection between neuronal activity and behavior. Optogenetics makes use of opsins, which are light activated ion-channels, ion pumps, or G-Protein coupled receptor (GPCR-based) proteins used to regulate cellular activity. Coupled with technological advances in genetics and optical physics/microscopy, optogenetics can be used to control specific populations of cells in a time-locked, spatially specific manner. The experiments possible with optogenetics depend largely on the capabilities and limitations of the opsin used; thus, there have been continuous efforts to design and employ new opsins with a variety …

Simplicity From Complexity: Sensing High-Dimensional Fluctuations Via Regulatory Network, Optimality In Allocating Cellular Resources, And Recovering Functional Groups Via Data-Driven Methods, Fang Yu

Arts & Sciences Graduate Student Theses and Dissertations

Biological systems must navigate dynamic and complex environments while operating under constraints such as limited molecular resources, biochemical noise, and structural trade-offs. This dissertation investigates three distinct cases in which biological systems allocate resources and process information efficiently, revealing emergent simplicity from underlying complexity. The first study develops a generalized end-product inhibition model with cross-talk and an excess of regulators, providing a proof-of-principle that simple biochemical circuits could, in principle, dynamically adjust their responsiveness to high-dimensional environmental variation. This result highlights how such circuits may allow adaptive filtering of both dominant and subdominant fluctuation modes. The second study, conducted in …

Oxycodone Self-Administration Modulates Ventral Pallidal Neuron Activity And Plasticity, Jessica Tooley

Arts & Sciences Graduate Student Theses and Dissertations

Opioid use disorder is an urgent public health crisis in the United States. Over 800,000 Americans have died from opioid-related overdoses since 2000. Nearly 30% of people who misuse opioids begin with prescription oral opioids, such as oxycodone, and continue misusing to avoid the immediate aversive state of withdrawal and the persistent dysphoria associated with protracted abstinence from opioids. The persistency of these dysphoric symptoms increases the risk of relapse even after long periods of abstinence. Treatment for opioid use disorder currently consists of pharmacological opioid treatment to reduce withdrawal symptoms and behavioral counseling. However, these strategies have significant real-world …

An Intervention To Empower People To Confront Sexism, Rebecca Grace Drake

Arts & Sciences Graduate Student Theses and Dissertations

Even though sexist comments and behavior occur frequently in everyday life, people do not often confront the individuals who are responsible. However, interpersonal bias confrontations can be powerful tools for reducing expressions of bias and norm setting. The current studies tested an intervention designed to increase confrontations by harnessing theory and research on what holds people back from confronting. We designed a half-hour intervention consisting of engaging and evidence-based videos on confronting bias and self-reflection exercises to increase personal relevance. The module aimed to boost confronting by intervening at multiple points of the decision-making process by increasing recognition of sexism, …
