Relating Neural Dynamics To Olfactory Coding And Behavior, Chao Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

Sensory stimuli often evoke temporal patterns of spiking activity across a population of neurons in the early processing stages. What features of these spatiotemporal responses encode behaviorally relevant information, and how dynamic processing of sensory signals facilitates information processing are fundamental problems in sensory neuroscience that remain to be understood. In this thesis, I have investigated these issues using a relatively simple invertebrate model (locusts; Schistocerca americana).

In locusts, odorants are transduced into electrical signals by olfactory sensory neurons in the antenna and are subsequently relayed to the downstream neural circuit in the antennal lobe (analogous to the olfactory bulb …

Micro-Determinants Of Income Inequality And Consumption In Rural Bangladesh, S Rahman

School of Engineering, Computing and Mathematics

The paper examines the extent to which household and regional characteristics influence income inequality and consumption/welfare based on an in-depth survey of 406 households from 21 villages in three regions of Bangladesh. Results show that the overall Gini coefficient for rural incomes is 0.43 but Gini-decomposition revealed that the contribution of mixed crop production to inequality is just 10 percent while “Green Revolution” technology contributes almost 29 percent. Land ownership, farm capital assets, modern irrigation, non-agricultural income, and household head”s education significantly increase consumption. Tenants and households with more dependents are doubly disadvantaged and consume significantly less. Regional factors also …

Automating Intensity Modulated Radiation Therapy Treatment Planning By Using Hierarchical Optimization, Paras Babu Tiwari

McKelvey School of Engineering Graduate Student Theses & Dissertations

The intensity modulated radiation therapy (IMRT) optimizes the beam’s intensity to deliver the prescribed dose to the target while minimizing the radiation exposure to normal structures. The IMRT optimization is a complex optimization problem because of the multiple conflicting objectives in it. Due to the complexity of the optimization, the IMRT treatment planning is still a trial and error process. Hierarchical optimization was proposed to automate the treatment planning process, but its potential has not been demonstrated in a clinical setting. Moreover, hierarchical optimization is slower than the traditional optimization. The dissertation studied a sampling algorithm to reduce the hierarchical …

Data Structures And Algorithms For Scalable Ndn Forwarding, Haowei Yuan

McKelvey School of Engineering Graduate Student Theses & Dissertations

Named Data Networking (NDN) is a recently proposed general-purpose network architecture that aims to address the limitations of the Internet Protocol (IP), while maintaining its strengths. NDN takes an information-centric approach, focusing on named data rather than computer addresses. In NDN, the content is identified by its name, and each NDN packet has a name that specifies the content it is fetching or delivering. Since there are no source and destination addresses in an NDN packet, it is forwarded based on a lookup of its name in the forwarding plane, which consists of the Forwarding Information Base (FIB), Pending Interest …

Ion Selectivity And Allostery In The Nak Channel, Joshua B. Brettmann

Arts & Sciences Graduate Student Theses and Dissertations

Ion channels require proper ion selectivity and regulated gating in order to perform their cellular functions. Bacterial ion channels serve as excellent model systems to study structure/function relationships concerning the fundamental processes of ion selectivity and gating. NaK, a non-selective cation channel from Bacillus cereus, has the conserved pore structure of K+ channels. However, its non-canonical selectivity filter structure leads to non-selectivity between Na+ and K+. Full selectivity is restored with two mutations that lead to the restoration of a Kcsa-like selectivity filter structure. Many mutations can be made to the selectivity filter of NaK without loss of protein stability …

Lysosomal Rnaset2 Is Required For Metabolic Stress-Mediated Ros Generation And Cell Death, George Caputa

Arts & Sciences Graduate Student Theses and Dissertations

Ectopic lipid deposition in non-adipose tissues is a hallmark of metabolic diseases, such as obesity and diabetes, and associated with cell dysfunction, cell death, and organ dysfunction. However, the molecular mechanisms linking excess free fatty acid to cell death are poorly understood. In order to identify genes critical for lipotoxicity, our lab performed a genetic screen in Chinese hamster ovary cells and isolated mutants that were resistant to lipotoxic death. In one of the lines, mutant 2B1, an allele encoding RNASET2, a ribonuclease of the T2 family, was disrupted by proviral insertion. We found that RNASET2 is induced during lipotoxicity …

Behavioral And Fmri-Based Characterization Of Cognitive Processes Supporting Learning And Retrieval Of Memory For Words In Young Adults, Binyam Nardos

Arts & Sciences Graduate Student Theses and Dissertations

A novel word is rarely defined explicitly during the first encounter. With repeated exposure, a decontextualized meaning of the word is integrated into semantic memory. With the overarching goal of characterizing the functional neuroanatomy of semantic processing in young adults, we employed a contextual word learning paradigm, creating novel synonyms for common animal/artifact nouns that, along with additional real words, served as stimuli for the lexical-decision based functional MRI (fMRI) experiment. Young adults (n=28) were given two types of word learning training administered in multiple sessions spread out over three days. The first type of training provided perceptual form-only training …

Science And Nature In The Medieval Ecological Imagination, Jessica Rezunyk

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores the intersections between nature and culture in medieval literature and art with particular focus on Geoffrey Chaucer’s House of Fame, the thirteenth-century French Bible Moralisée (Vienna, Österreichische Nationalbibliothek Codex Vindobonensis 2554), and William Langland’s Piers Plowman. Current academic paradigms tend to place the study of nature firmly within the sciences and the study of culture firmly within the humanities, creating a gap between the fields that effectively isolates their respective methodologies and vocabularies from one another. This dissertation seeks to bridge that gap between the sciences and the humanities by approaching medieval literature through the lens of …

Investigation Of 89zr-Siderophores As Molecular Imaging Agents For Positron Emission Tomography Imaging Of Bacterial Infections, Nora C. M. Goscinski

Arts & Sciences Graduate Student Theses and Dissertations

Siderophores are small molecules synthesized by bacteria to harvest Fe³⁺ from their environment. In infection scenarios, their production can increase infection virulence by increasing the ability of bacteria to obtain Fe³⁺ and therefore grow more rapidly. The selective uptake of siderophores in vivo in multi-bacteria environments indicates that this class of molecules has a potential use as selective imaging agents. In this work, DFO-NCS and a library of trihydroxamate siderophores were evaluated as vehicles to deliver ⁸⁹Zr selectively to bacteria for Positron Emission Tomography (PET) imaging of bacterial infections. Productive work with radiometals involves thorough knowledge of …

The Role Of Trauma And Mental Health Problems In The Perpetration Of Intimate Partner Violence In Post-Genocide Rwanda, Sarah Myers Tlapek

Arts & Sciences Graduate Student Theses and Dissertations

Exposure to political violence or war is associated with intimate partner violence (IPV) in post-conflict settings (Clark et al., 2010; Gupta, Reed, Kelly, Stein, & Williams, 2012), and civilians and veterans who develop posttraumatic stress disorder (PTSD) after exposure to combat or violence are more likely to perpetrate violence against an intimate partner (Taft, Watkins, Stafford, Street, & Monson, 2011). Rwandan health professionals estimate that after the 1994 genocide more than one-quarter of the country’s population now suffers from PTSD (Munyandamutsa, Nkubamugisha, Gex-Fabry, & Eytan, 2012). Although the majority of Rwandan women (56%) have experienced IPV in their lifetime (National …

Molecular Mechanisms Of Axon Growth And Regeneration, Dana Watt

Arts & Sciences Graduate Student Theses and Dissertations

Neurons are cells with unique and extremely polarized morphologies. The axon allows communication between the cell soma and the distantly located synaptic terminal and can extend up to one meter in humans. This exceptional cellular structure therefore has specialized biological processes dedicated to its growth, maintenance and regeneration. The structure that carries out axon elongation during development and regeneration is the growth cone, which features a cytoskeletal structure that is both highly dynamic yet consistent in overall organization. The growth cone coordinates a leading edge of dynamic actin with the microtubules of the growing axon, enabling directed outgrowth while maintaining …

Quaternary Chronology And Stratigraphy Of Mickey Springs, Oregon, Leslie Allen Mowbray

Dissertations and Theses

Mickey Springs in the Alvord Desert, southeast Oregon, is analogous to other Basin and Range hydrothermal systems where the requisite conditions of heat source and permeable pathways are met through crustal thinning due to normal faulting. This study examines the morphology and lifespan of near-surface spring features through use of ground penetrating radar, thermoluminescence (TL) dating, and elevation modeling. Duration of hydrothermal activity at Mickey Springs has not previously been determined, and age determinations of sinter at the site are conflicting. The reason for and timing of this change in silica saturation in the hydrothermal fluid has not been resolved. …
