Using Memory Forensics To Analyze Programming Language Runtimes, Modhuparna Manna

LSU Doctoral Dissertations

The continued increase in the use of computer systems in recent times has led to a significant rise in the capabilities of malware and attacker toolkits that target different operating systems and their users. Over the last several years, cybersecurity threat reports have documented numerous instances of users that were targeted by governments, intelligence agencies, and criminal groups, and the result was that the victims ended up having highly sophisticated malware installed on their systems. Unfortunately, the rise of these threats has not been met with equal research and development of defensive mechanisms that can detect and analyze such malware. …

Developmental Functioning Of Infants And Toddlers With Neurodevelopmental Disorders, Megan Callahan

LSU Master's Theses

Autism spectrum disorder (ASD), epilepsy, and cerebral palsy (CP) are some of the most common neurodevelopmental disorders among children with prevalence rates of 1.85% (Maenner et al., 2020), 1.2% (Zack & Kobau, 2017), and between 0.21 and 0.31% (Christensen et al., 2013), respectively. These neurodevelopmental disorders are highly comorbid with each other and with other disorders, such as intellectual disability (ID). While previous research has investigated developmental functioning in these neurodevelopmental disorders, it has primarily focused on only two at a time and in older children or adults. The current study aimed to investigate developmental functioning in these neurodevelopmental disorders …

Application Of Gravity Data For Hydrocarbon Exploration Using Machine Learning Assisted Workflow, Oluwafemi Temidayo Alaofin

LSU Master's Theses

Gravity survey has played an essential role in many geoscience fields ever since it was conducted, especially as an early screening tool for subsurface hydrocarbon exploration. With continued improvement in data processing techniques and gravity survey accuracy, in-depth gravity anomaly studies, such as characterization of Bouguer and isostatic residual anomalies, have the potential to delineate prolific regional structures and hydrocarbon basins. In this study, we focus on developing a cost-effective, quick, and computationally efficient screening tool for hydrocarbon exploration using gravity data employing machine learning techniques. Since land-based gravity surveys are often expensive and difficult to obtain in remote places, …

Search For Continuous Gravitational Waves From 20 Accreting Millisecond X-Ray Pulsars In O3 Ligo Data, R. Abbott, T. D. Abbott, F. Acernese, K. Ackley, C. Adams

Faculty Publications

Results are presented of searches for continuous gravitational waves from 20 accreting millisecond x-ray pulsars with accurately measured spin frequencies and orbital parameters, using data from the third observing run of the Advanced LIGO and Advanced Virgo detectors. The search algorithm uses a hidden Markov model, where the transition probabilities allow the frequency to wander according to an unbiased random walk, while the J-statistic maximum-likelihood matched filter tracks the binary orbital phase. Three narrow subbands are searched for each target, centered on harmonics of the measured spin frequency. The search yields 16 candidates, consistent with a false alarm probability of …

The Lived Experiences Of Migrant Domestic Workers In Taiwan, Li-Yu Liao

LSU Doctoral Dissertations

The constantly increasing demand of domestic workers in developed and newly industrialized countries had prompted many women of less developed countries migrating to engage in transnational domestic work. Among these newly industrialized countries (NICs) in Asia, Taiwan is one of them with burgeoning market of domestic work. In 2019, Taiwan accommodated 261,457 foreign domestic workers. Indonesian, Filipino, and Vietnamese women constitute the three major groups of the population. Compare to their counterparts in other host countries in Asia such as Hong Kong and Singapore, migrant domestic workers in Taiwan were understudied. This research was committed to explore the experiences of …

Towards A Quantum Notion Of Covariance In Spherically Symmetric Loop Quantum Gravity, Rodolfo Gambini, Javier Olmedo, Jorge Pullin

Faculty Publications

The covariance of loop quantum gravity studies of spherically symmetric space-times has recently been questioned. This is a reasonable worry, given that they are formulated in terms of slicing-dependent variables. We show explicitly that the resulting space-times, obtained from Dirac observables of the quantum theory, are covariant in the usual sense of the way-they preserve the quantum line element-for any gauge that is stationary (in the exterior, if there is a horizon). The construction depends crucially on the details of the Abelianized quantization considered, the satisfaction of the quantum constraints, and the recovery of standard general relativity in the classical …

Characterizing Middle School Students' Physical Literacy Development: A Self-Determination Theory-Based Pilot Intervention In Physical Education, Yang Liu, Senlin Chen

Faculty Publications

Purpose: Positive youth development (PYD) can be achieved through effective and purposeful instructions in physical education (PE) and other relevant experiences both in and beyond schools. Students' PYD is associated with their physical literacy (PL) development, which has become a primary emphasis of PE, especially in the United States, in recent years. This study aimed to (a) characterize middle school students' physical literacy (PL) and (b) capture their PL developing trajectories in light of receiving a self-determination theory (SDT)-based pedagogical workshop, with the long-term vision on PYD. Methods: Participants (N = 226) completed the Canadian Assessment of Physical Literacy (CAPL-2) …

A Case Study Of Fourth Grade Students' Literacy Difficulties With Mathematical Word Problems, Rosalind Hudson

LSU Doctoral Dissertations

ABSTRACT

Students have had difficulties with mathematical word problems since they were introduced in their early elementary grades. Elementary teachers have dealt with student difficulties in solving mathematical word problems. In addition, elementary teachers are always implementing and searching for research-based strategies to remediate the deficits in solving mathematical word problems. Year after year across the United States, local education agencies implement math and reading curriculums to support students learning in mathematical word problem solving with reading comprehension, but students are still not able to describe their difficulties when they are given mathematical word problems to solve with all the …

Performance Of Upland Cotton Under A Hairy Vetch Regiment From A Crop Insurance Perspective, Cameron J. Roig

LSU Master's Theses

Cover crop’s value from a policy perspective lies in potential environmental benefits if used en masse including waterway protection from farm runoff, reducing soil erosion, and sequestering carbon. The ultimate decision to adopt cover crops lies with farmers however and their decisions are largely driven by business performance. Because of this, economic research into cover crops has mostly revolved around factors influential to farmer’s adoption decisions with direct and indirect policy effects being lesser researched. Crop insurance, a nearly ubiquitous federally administered risk management tool for farms in the United States, is often cited as a suspected negative influence for …

Developmental Functioning Of Infants And Toddlers With Autism And Down Syndrome, Celeste Tevis

LSU Master's Theses

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, as well as restricted interests and repetitive behaviors. Approximately 10% of individuals with ASD also have comorbid genetic or chromosomal conditions, like Down Syndrome (DS). While it was once believed that DS and ASD rarely co-occurred, it has been demonstrated that it is not uncommon for children with DS to also meet criteria for ASD. Due to the difficulties in differentiating between impairments associated with intellectual disability (ID) and ASD symptomology, DS often leads to delayed or misdiagnoses of ASD. This can interfere with early intervention …

Current Methods And Future Directions In Avian Diet Analysis, Brandon D. Hoenig, Allison M. Snider, Anna M. Forsman, Keith A. Hobson, Steven C. Latta, Eliot T. Miller, Michael J. Polito, Luke L. Powell, Samantha L. Rogers, Thomas W. Sherry, David P.L. Toews, Andreanna J. Welch, Sabrina S. Taylor, Brady A. Porter

Faculty Publications

Identifying the composition of avian diets is a critical step in characterizing the roles of birds within ecosystems. However, because birds are a diverse taxonomic group with equally diverse dietary habits, gaining an accurate and thorough understanding of avian diet can be difficult. In addition to overcoming the inherent difficulties of studying birds, the field is advancing rapidly, and researchers are challenged with a myriad of methods to study avian diet, a task that has only become more difficult with the introduction of laboratory techniques to dietary studies. Because methodology drives inference, it is important that researchers are aware of …

Instructional Design Framework For Construction Materials Training, Hazem Jadallah, Carol J. Friedland, Isabelina Nahmens, Charles Pecquet, Charles Berryman, Yimin Zhu

Faculty Publications

The construction industry is suffering, in part, from a lack of training programs offered to the construction workforce. Unfortunately, most construction training and education research focuses on university student education. Integrating education science theory into construction workforce training has the potential to improve industry training but there is a dearth of studies that present details of this integration process. To address this gap, a training framework was developed to educate material stakeholders on material properties, selection, and installation. This framework is based on andragogical and Universal Design for Learning (UDL) principles. An assessment method evaluates training agendas to improve upon …

Women Of Power: Mapping The Spiritual Journeys Of Caribbean Women Across Regional Fiction As Portrayed In The Book Of Night Women, Texaco, And Erzulie's Skirt, Natalie Sandy D'Auvergne-Lamotte

LSU Doctoral Dissertations

Contemporary Caribbean fiction serves as an active agent for refining and expanding definitions of Caribbeanness. This study aims at demonstrating how Caribbean writers use representations of Caribbean women to contribute to an opaquer regional vision that argues against homogenizing ideas of Caribbeanness. The Book of Night Women, Texaco, and Erzulie’s Skirt, respectively written by Marlon James (Jamaica), Patrick Chamoiseau (Martinique), and Anna-Maurine Lara (Dominican Republic), work by making space for more historically accurate and locally representative images of Caribbeanness through the Caribbean women they portray. Though characters live on different islands (at different times), they still manage to represent …

Distributed Matrix Tiling Using A Hypergraph Labeling Formulation, Avah Banerjee, Maxwell Reeser, Guoli Ding

Faculty Publications

Partitioning large matrices is an important problem in distributed linear algebra computing, used in ML among others. Briefly, our goal is to perform a sequence of matrix algebra operations in a distributed manner on these large matrices. However, not all partitioning schemes work well with different matrix algebra operations and their implementations (algorithms). This is a type of data tiling problem. In this paper we consider a data tiling problem using hypergraphs. We prove some hardness results and give a theoretical characterization of its complexity on random instances. Additionally we develop a greedy algorithm and experimentally show its efficacy.

Brazilian Mangroves: Blue Carbon Hotspots Of National And Global Relevance To Natural Climate Solutions, Andre S. Rovai, Robert R. Twilley, Thomas A. Worthington, Pablo Riul

Faculty Publications

Mangroves are known for large carbon stocks and high sequestration rates in biomass and soils, making these intertidal wetlands a cost-effective strategy for some nations to compensate for a portion of their carbon dioxide (CO2) emissions. However, few countries have the national-level inventories required to support the inclusion of mangroves into national carbon credit markets. This is the case for Brazil, home of the second largest mangrove area in the world but lacking an integrated mangrove carbon inventory that captures the diversity of coastline types and climatic zones in which mangroves are present. Here we reviewed published datasets to derive …

Isocaloric Low Protein Diet In A Mouse Model For Vanishing White Matter Does Not Impact Isr Deregulation In Brain, But Reveals Isr Deregulation In Liver, Lisanne E. Wisse, Denise Visser, Timo J. Ter Braak, Abdellatif Bakkali, Eduard A. Struys, Christopher D. Morrison, Marjo S. Van Der Knaap, Truus E.M. Abbink

Division of Basic Science Faculty Publications

Objective: Vanishing white matter (VWM) is a genetic brain white matter disorder caused by mutations in eIF2B. eIF2B is central in the integrated stress response (ISR), during which its activity is inhibited by various cellular stresses. VWM is a chronic progressive disease with episodes of rapid neurological deterioration provoked by stresses. VWM patients and VWM mouse models show ISR deregulation in brain, correlating with chronic disease development. ISR inhibition ameliorates the chronic disease in VWM mice. The subacute deteriorations have not been modeled yet. We hypothesized that ISR activation could worsen disease progression in mice and model the episodic neurological …

Obesity, Body Composition, And Sex Hormones: Implications For Cardiovascular Risk, Prachi Singh, Naima Covassin, Kara Marlatt, Kishore M. Gadde, Steven B. Heymsfield

Clinical Research Faculty Publications

Cardiovascular disease (CVD) continues to be the leading cause of death in adults, highlighting the need to develop novel strategies to mitigate cardiovascular risk. The advancing obesity epidemic is now threatening the gains in CVD risk reduction brought about by contemporary pharmaceu-tical and surgical interventions. There are sex differences in the development and outcomes of CVD; premenopausal women have significantly lower CVD risk than men of the same age, but women lose this advantage as they transition to menopause, an observation suggesting potential role of sex hormones in determining CVD risk. Clear differences in obesity and regional fat distribution among …

Guesswork With Quantum Side Information, Eric P. Hanson, Vishal Katariya, Nilanjana Datta, Mark M. Wilde

Faculty Publications

What is the minimum number of guesses needed on average to guess a realization of a random variable correctly The answer to this question led to the introduction of a quantity called guesswork by Massey in 1994, which can be viewed as an alternate security criterion to entropy. In this paper, we consider the guesswork in the presence of quantum side information, and show that a general sequential guessing strategy is equivalent to performing a single quantum measurement and choosing a guessing strategy based on the outcome. We use this result to deduce entropic one-shot and asymptotic bounds on the …

The Cacophony Of Politics: Northern Democrats And The American Civil War, Michael Todd Landis

Civil War Book Review

J. Matthew Gallman delights in the chaos, offering a dizzying litany of anecdotes and personalities to give readers a sense of the opacity of partisanship in the early 1860s. “One chief goal here is to demonstrate how fundamentally messy, and often inconsistent, Civil War partisan politics really was,” he warns at the start.

Buried Dreams: The Hoosac Tunnel And The Demise Of The Railroad Age, Scott Randolph

Civil War Book Review

In Buried Dreams, Andrew R. Black chronicles the largely forgotten effort of Massachusetts to surmount the Berkshires and build a permanent link with the interior in order to retain the Commonwealth’s, and particularly the port of Boston’s economic prominence. This effort, the 4.75 mile-long Hoosac Tunnel, eventually took twenty-four years, ended over one hundred lives, and consumed more than $20,000,000 in state funds. Born of a desire for boundless western bounty, it never fulfilled the lofty expectations its supporters heaped upon it. Predicted by its early enthusiasts (tunnelites) to take but a few years, and presenting few if any …

The Souls Of Womenfolk: The Religious Cultures Of Enslaved Women In The Lower South, Emily Clark

Civil War Book Review

Reviewer Emily Suzanne Clark writes that Alexis Wells-Oghoghomeh’s The Souls of Womenfolk: The Religious Cultures of Enslaved Women in the Lower South “is one of the most important books in African American religious history of the past decade.” Clark concludes that “By placing women at the center,” Oghoghomeh “shifts the field’s focus away from the pulpit as a means of empowerment.”

The Siege Of Vicksburg: Climax Of The Campaign To Open The Mississippi River, May 23 – July 4, 1863, Thomas F. Army

Civil War Book Review

Reviewer Thomas F. Army writes that in The Siege of Vicksburg: Climax of the Campaign to Open the Mississippi River, May 23 – July 4, 1863, author Timothy B. Smith followed John Keegan’s dictate that military historians should produce analysis that goes beyond “colored maps,” Though Smith dedicates considerable attention to the tactical and strategic elements of the siege, he balances his technical analysis with an examination of the human suffering the siege begat. Army found many strengths in Smith’s work, including his emphasis that contingency mattered—Vicksburg’s fall was not inevitable. Smith’s The Siege of Vicksburg “is an important …

Modeling Crash Severity And Collision Types Using Machine Learning, Amit Kumar, Hari Krishnan Melempat Kalapurayil

Publications

Traffic safety analysis is the fundamental step for reducing economic, social, and environmental cost incurred due to traffic accidents. The essence of traffic safety is understanding the factors affecting crash occurrence, injury severity and collision type and their underlying relationships and predict-prevent future crash instances. Crash injury severity studies in past have utilized numerous statistical, econometric and Machine Learning (ML) and Artificial Intelligence (AI) tools to extract the underlying relationship between the crash causal factors and the consequent severity or collision type. The study aims to explore the Multi-Label Classification (MLC) tool from the domain of Artificial Intelligence (AI) for …
