From the Baroque era, François Couperin, Jean-Baptiste Barrière, and Martin Berteau are …

Finding Music In Chaos: Designing And Composing With Virtual Instruments Inspired By Chaotic Equations, Landon P. Viator

LSU Doctoral Dissertations

Using chaos theory to design novel audio synthesis engines has been explored little in computer music. This could be because of the difficulty of obtaining harmonic tones or the likelihood of chaos-based synthesis engines to explode, which then requires re-instantiating of the engine to proceed with sound production. This process is not desirable when composing because of the time wasted fixing the synthesis engine instead of the composer being able to focus completely on the creative aspects of composition. One way to remedy these issues is to connect chaotic equations to individual parts of the synthesis engine instead of relying …

James I: Monarchial Representation And English Identity, Elizabeth Maria Taylor

LSU Doctoral Dissertations

This work unpacks James’s representational performance and the issues he faced in assimilating himself into English identity during him time on the English throne. He implemented tropes he previously utilized in Scotland, presenting himself as Solomon, David, Constantine, a philosopher-king, and Rex Pacificus. James relied upon print for his public representation, he was an avid writer and seems to have thought of himself as something of a theologian, for he frequently commented upon religious doctrine and paid acute attention to sermons. This dissertation explores his entrance to England, the union debates, the Gunpowder Plot and its remembrance, James’s religious …

Interactions Between Federal Education Tax Credits And State-Based Aid Programs: An Analysis Of State Budgeting For Higher Education, Anna Castrillo Bartel

LSU Doctoral Dissertations

Prior empirical analyses on federal education tax credits have concentrated on the individual and institutional unit of analysis. These outcomes indicate mostly null effects on promoting college enrollments, along with distribution to higher incomes, and mixed results on tuition and fee increases. This analysis utilized institutional and state unit of analysis over a longer timeframe, Tax Year 2001 to Tax Year 2016, using difference-in-differences estimation to analyze the effects of education tax credits. The results indicated states have decreased appropriations to public, two-year institutions (charging less than $4,000) 14% less than their higher-priced counterparts, while states provided more appropriations to …

Understanding And Optimizing Flash-Based Key-Value Systems In Data Centers, Yichen Jia

LSU Doctoral Dissertations

Flash-based key-value systems are widely deployed in today’s data centers for providing high-speed data processing services. These systems deploy flash-friendly data structures, such as slab and Log Structured Merge(LSM) tree, on flash-based Solid State Drives(SSDs) and provide efficient solutions in caching and storage scenarios. With the rapid evolution of data centers, there appear plenty of challenges and opportunities for future optimizations.

In this dissertation, we focus on understanding and optimizing flash-based key-value systems from the perspective of workloads, software, and hardware as data centers evolve. We first propose an on-line compression scheme, called SlimCache, considering the unique characteristics of key-value …

Overlaps Of Deformed And Non-Deformed Harmonic Oscillator Basis States, David Kekejian, Jerry P. Draayer, Tomáš Dytrych, Kristina D. Launey

Faculty Publications

A systematic approach for expanding non-deformed harmonic oscillator basis states in terms of deformed ones, and vice versa, is presented. The objective is to provide analytical results for calculating these overlaps (transformation brackets) between deformed and non-deformed basis states in spherical, cylindrical, and Cartesian coordinates. These overlaps can be used for reducing the complexity of different research problems that employ three-dimensional harmonic oscillator basis states, for example as used in coherent state theory and the nuclear shell-model, especially within the context of ab initio symmetry-adapted no-core shell model.

Prior to magnetic resonance images, participants had completed an average of 10 years of random assignment to either multidomain intervention targeting weight loss or a control condition of diabetes support and education. Total (summed gray …

Correctional Officers' Mental Health Literacy And Attitudes Toward Offenders With Mental Illness, Amber Rebecca Hebert

LSU Doctoral Dissertations

Overrepresentation of people with mental illness in the criminal justice system is a major societal problem. According to the Bureau of Justice Statistics, nearly three quarters of people housed in local jails report having symptoms suggestive of mental illness. Individual consequences to incarceration for people diagnosed with a mental illness include disruption in treatment, increase in symptomology, exposure to violence, and victimization. Correctional officers are an important component to the criminal justice system but their role in the lives of offenders with mental illness has been understudied. The current study explored the mental health knowledge, attitudes, and personal experiences of …

Efficiently Computable Bounds For Magic State Distillation, Xin Wang, Mark M. Wilde, Yuan Su

Faculty Publications

Magic-state distillation (or nonstabilizer state manipulation) is a crucial component in the leading approaches to realizing scalable, fault-tolerant, and universal quantum computation. Related to nonstabilizer state manipulation is the resource theory of nonstabilizer states, for which one of the goals is to characterize and quantify nonstabilizerness of a quantum state. In this Letter, we introduce the family of thauma measures to quantify the amount of nonstabilizerness in a quantum state, and we exploit this family of measures to address several open questions in the resource theory of nonstabilizer states. As a first application, we establish the hypothesis testing thauma as …

Natural Variation And Evolutionary Responses To Climate Change Stressors In Marine Invertebrates, Joanna Sarah Griffiths

LSU Doctoral Dissertations

Our rapidly changing climate is putting many species at risk of extinction and there is an urgent need to understand how species will respond to these changes. In this dissertation, I evaluate how three species of marine invertebrates (corals, oysters, and copepods) respond to stressful conditions in their current environments and how plasticity and evolutionary adaptation could alter their response to future climate change stressors. I first employed a space for time study to elucidate population differences in the response of cold-water corals, Balanophyllia elegans, to future ocean acidification. I found evidence that upwelling history (natural low pH exposure) influences …

Essays On Mortgage Portfolio Diversification, Timothy Patrick Dombrowski

LSU Doctoral Dissertations

Portfolios of mortgage loans played an important role in the Great Recession and continue to compose a material part of bank assets. The distribution of mortgage portfolio returns, and consequently, the risk of these portfolios, is quite distinct even from other fixed income asset classes. This dissertation contains three essays, each aiming to analyze a specific component of risk in mortgage portfolios and role of geographical diversification in reducing this risk.

The first essay investigates how cross-sectional dependence in the underlying properties flows through to the loan returns, and thus, the risk of the portfolio. In addition to demonstrating this …

The Indigenous Communal Sense In Enrique Dussel's Concept Of People, Erick Javier Padilla

LSU Master's Theses

In Twenty Theses on Politics, Argentine-Mexican philosopher Enrique Dussel compares the concept of people with two Indigenous terms: The Aztec altepetl and the Mayan Amaq’. Both concepts mean ‘community’ or ‘people,’ and ‘us/we.’ However, beyond his reference to Carlos Lenkersdorf’s book Filosofar en clave tojolabal (Philosophizing in Tojolabal Code), Dussel delves not further into these Indigenous words and their implications to understand what he means by people. Focusing on the work of Carlos Lenkersdorf (2005), Gladys Tzul Tzul (2018), Alejandra Aquino Moreschi (2013), Raúl Madrid (2014) and Josef Estermann (2006), I shall examine how the political proceeding …

The Seasonal Evolution Of Albedo Across Glaciers And The Surrounding Landscape Of Taylor Valley, Antarctica, Anna Bergstrom, Michael N. Gooseff, Madeline Myers, Peter T. Doran, Julian M. Cross

Faculty Publications

© Author(s) 2020. The McMurdo Dry Valleys (MDVs) of Antarctica are a polar desert ecosystem consisting of alpine glaciers, ice-covered lakes, streams, and expanses of vegetation-free rocky soil. Because average summer temperatures are close to 0 °C, the MDV ecosystem in general, and glacier melt dynamics in particular, are both closely linked to the energy balance. A slight increase in incoming radiation or change in albedo can have large effects on the timing and volume of meltwater. However, the seasonal evolution or spatial variability of albedo in the valleys has yet to fully characterized. In this study, we aim to …

Effects Of Freshwater Inflow On Nekton Assemblages And Blue Crab Populations In Southeastern Louisiana, Caleb Benjamin Taylor

LSU Master's Theses

Estuaries along the northern Gulf of Mexico represent some of the most productive ecosystems in the world, providing vital habitat for many recreationally and commercially valuable species, including the blue crab, Callinectes sapidus. The mixing of fresh river and saline ocean water in coastal estuaries contribute to this productivity. Dominated by large river influences and consisting of multiple estuaries, Louisiana contributes the largest commercial fishery in the Gulf of Mexico, and remains, on average, the largest supplier of blue crabs in the nation. However, across southeast Louisiana, freshwater flow is largely dependent on Mississippi River discharge, which is highly …

Hyaluronic Acid-Cellulose Composites As Patches For Minimizing Bacterial Infections, Kelsey M. Lopez, Sudhir Ravula, Rocío L. Pérez, Caitlan E. Ayala, Jack N. Losso, Marlene E. Janes, Isiah M. Warner

Faculty Publications

Copyright © 2020 American Chemical Society. A facile method was used to synthesize biocomposites containing differing ratios of hyaluronic acid (HA) and cellulose (CEL). Based on the properties of the individual polymers, the resultant composite materials may have potentially great wound care properties. In the method outlined here, 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]), a simple ionic liquid, was used as the sole solvent without chemical modifiers to dissolve the biopolymers at ratios of 1:1 and 2:1 HA to CEL. This method was completely recyclable since the ionic liquid, [Bmim][Cl], can be recovered. Results from spectroscopic measurements [Fourier transform infrared (FT-IR) and X-ray …

Climate And Plant Community Diversity In Space And Time, Susan Harrison, Marko J. Spasojevic, Daijiang Li

Faculty Publications

© 2020 National Academy of Sciences. All rights reserved. Climate strongly shapes plant diversity over large spatial scales, with relatively warm and wet (benign, productive) regions supporting greater numbers of species. Unresolved aspects of this relationship include what causes it, whether it permeates to community diversity at smaller spatial scales, whether it is accompanied by patterns in functional and phylogenetic diversity as some hypotheses predict, and whether it is paralleled by climate-driven changes in diversity over time. Here, studies of Californian plants are reviewed and new analyses are conducted to synthesize climate-diversity relationships in space and time. Across spatial scales …

Effect Of Channelized And Unchannelized Lateral Outflow On Three-Dimensional Flow Structure And Sediment Transport Mechanisms In A River Delta, Mohammad Kifayath Chowdhury

LSU Master's Theses

Spatial and temporal patterns in three-dimensional flow structure have been linked to channel morphology and processes in many environments, including river meander bends, confluences-diffluences, and bedrock canyons. However, there is not yet an understanding of how channelized and gradual, distributed lateral outflows that are often prevalent in deltaic distributary systems influence three-dimensional flow structure and sediment transport mechanisms. This thesis presents an analysis of 3D flow structure data collected from Wax Lake Delta, a naturally developing river-dominated delta in the northern Gulf of Mexico. Three hydrographic surveys were conducted using boat-mounted acoustic Doppler current profiler (ADCP) at two sites: an …

Contextual Adjustment Of The Ite Trip Generation Rates Using Wi-Fi And Bluetooth Technologies, Saba Doulabi

LSU Master's Theses

The ITE Trip Generation Handbook has been in common use for about half a century to estimate vehicle trips generated by more than 172 land use categories as a function of establishment size (floor area) only. However, observed trip rates display a huge error range across different sites. Although contextual adjustment factors can ameliorate the error in the ITE trip generation estimates considerably, local site-specific trip generation rates should be collected for this purpose. Due to the huge time and monetary costs of data collection, adjusting the ITE trip generation rate is ignored by many jurisdictions. The primary contribution of …

Long-Term Impact Of Welfare Reform: Biopsychosocial Barriers To Successful Transition Away From Welfare Reliance Among Rural Women In Louisiana, Jake Jerome Guidry

LSU Master's Theses

The discussion regarding government benefits and reliance on welfare benefits is one that takes place in arenas of policymaking and academia alike. These discussions often focus on poverty that exists in densely populated metropolitan areas, resulting in a scarcity of research regarding unique characteristics of rural poverty. Eighty-four rural Louisiana women participated in a longitudinal study of the impacts of welfare reform in their lives. Twenty years later, two (N = 2) rural Louisiana women, each former welfare recipients, participated in an in-depth qualitative case study examining their transition away from welfare programs. Data show that neither woman was …

Parkinson's Disease In Louisiana, 1999-2012: Based On Hospital Primary Discharge Diagnoses, Incidence, And Risk In Relation To Local Agricultural Crops, Pesticides, And Aquifer Recharge, Martin E. Hugh-Jones, R. Hampton Peele, Vincent L. Wilson

Faculty Publications

The two major causes of Parkinson's disease (PD) are genetic susceptibility and exposure to agricultural pesticides. Access to 23,224 individuals' hospital primary discharge diagnoses of PD allowed the mapping of cases against known crop distributions and pesticides. Our main objective was to map PD risks (cases per 10,000 people) against crops and their pesticides. The ZIP Code address locations, and the 2000 and 2010 census data, were used to map the risks of PD throughout Louisiana and in relation to United States Department of Agriculture (USDA)-recorded crops. The introduction of glyphosate-resistant crops appears to have initiated the PD disappearance from …

Minimizing Total Energy Cost And Tardiness Penalty For A Scheduling-Layout Problem In A Flexible Job Shop System: A Comparison Of Four Metaheuristic Algorithms, Ahmad Ebrahimi, Hyun Woo Jeon, Seokgi Lee, Chao Wang

Faculty Publications

Job scheduling and machine layout are interrelated in improving energy consumption (EC) and productivity measures such as tardiness and represent two important decisions that must be made by manufacturers. This interdependency can be explained by transportation time, which connects scheduling and layout. Scheduling and layout, however, have not been thoroughly studied in conjunction using an integrated model in the context of sustainable manufacturing. Hence, we propose an energy-aware optimization model in which scheduling is integrated with layout in a single-level framework. More specifically, a single objective function is defined to minimize the facility energy cost and the job tardiness penalty, …

Modeling And Data Infrastructure For Human-Centric Design And Operation Of Sustainable, Healthy Buildings Through A Case Study, Yong X. Tao, Yimin Zhu, Ulrike Passe

Faculty Publications

This paper focuses on data infrastructure that is central to the modeling of design and operation of sustainable and healthy buildings. While reducing energy consumption by making buildings more energy efficient has been touted as an easily obtainable approach to promoting carbon-neutral energy societies, the sustainable buildings’ benefits and impacts on human wellbeing have not been clearly quantified to the extent that they may directly influence the decision of adopting sustainable building designs. The authors argue that focusing on the wellbeing of people occupying the buildings will lead to significant changes in the decision-making process of the design and operation …

Low-Phosphate Chromatin Dynamics Predict A Cell Wall Remodeling Network In Rice Shoots, Maryam Foroozani, Sara Zahraeifard, Dong Ha Oh, Guannan Wang, Maheshi Dassanayake, Aaron P. Smith

Faculty Publications

© 2020 American Society of Plant Biologists. All Rights Reserved. Phosphorus (P) is an essential plant macronutrient vital to fundamental metabolic processes. Plant-available P is low in most soils, making it a frequent limiter of growth. Declining P reserves for fertilizer production exacerbates this agricultural challenge. Plants modulate complex responses to fluctuating P levels via global transcriptional regulatory networks. Although chromatin structure plays a substantial role in controlling gene expression, the chromatin dynamics involved in regulating P homeostasis have not been determined. Here we define distinct chromatin states across the rice (Oryza sativa) genome by integrating multiple chromatin marks, including …

Heat Shock Protein 70 Levels And Post-Harvest Survival Of Eastern Oysters Following Sublethal Heat Shock In The Laboratory Or Conditioning In The Field, Sandra M. Casas, Jerome F. La Peyre

Faculty Publications

© 2020, Cell Stress Society International. A major problem of storing and shipping eastern oysters (Crassostrea virginica) from the Northern Gulf of Mexico in summer and early fall is their elevated mortality. A study was therefore conducted to determine whether heat shocking the oysters or conditioning them to aerial exposure prior to harvest could reduce their mortality during cold storage. Increasing the levels of stress proteins in bivalves has been shown to reduce their mortality when exposed to additional stressors. In this study, the levels of heat shock protein 70 (HSP70) proteins and cumulative mortality during cold storage, out of …

Faculty Publications

© 2020 The Authors. Animal Genetics published by John Wiley & Sons Ltd on behalf of Stichting International Foundation for Animal Genetics Resistance to gastrointestinal nematodes has previously been shown to be a moderately heritable trait in some breeds of sheep, but the mechanisms of resistance are not well understood. Selection for resistance currently relies upon faecal egg counts (FEC), blood packed cell volumes and FAMACHA visual indicator scores of anaemia. Identifying genomic markers associated with disease resistance would potentially improve the selection process and provide a more reliable means of classifying and understanding the biology behind resistant and susceptible …

Over Height Impact Avoidance And Incident Detection System, Suvash Chapain, Aly Mousaad Aly

Faculty Publications

During the construction and repair of bridges, work platforms or construction-related containment may result in restricted vertical clearances at a work location. Some tractor-trailer combinations are prone to over-height collisions at these locations. Collisions are a hazard to all drivers, and repair of the damage typically causes traffic delays. Appropriate solutions to this problem will focus on the prevention of collisions by detecting over-height vehicles and directing the drivers to take an alternate safe route. This presentation addresses the design and functionality of smart detection/alert systems that can be set up well in advance of a known vertical clearance restriction …

Two Weeks Of Moderate Hypoxia Improves Glucose Tolerance In Individuals With Type 2 Diabetes, Kara L. Marlatt, Frank L. Greenway, J. Kyle Schwab, Eric Ravussin

Clinical Research Faculty Publications

We previously showed that nightly exposure to moderate hypoxia reduces fasting glucose levels and improves both whole-body skeletal muscle and hepatic insulin sensitivity in individuals with obesity. The goal of this study was to extend this observation in an “at home” setting and determine if nightly exposure to moderate hypoxia improves glucose tolerance in individuals with type 2 diabetes. Eight adults, ages 20–65 years with type 2 diabetes enrolled in our study and slept for 14 consecutive nights at home in a hypoxic tent maintained at 15% O2 (~2400 m). The primary endpoint was insulin sensitivity (Matsuda Index) calculated from …
