Arbitrage-Free Pricing With Diffusion-Dependent Jumps, Hamza A. Virk, Yihren Wu, Majnu John Jan 2026

Arbitrage-Free Pricing With Diffusion-Dependent Jumps, Hamza A. Virk, Yihren Wu, Majnu John

Journal of Stochastic Analysis

Standard jump-diffusion models assume independence between jumps and diffusion components. We develop a multi-type jump-diffusion model where jump occurrence and magnitude depend on contemporaneous diffusion movements. Unlike previous one-sided models that create arbitrage opportunities, our framework includes upward and downward jumps triggered by both large upward and large downward diffusion increments. We derive the explicit no-arbitrage condition linking the physical drift to model pa- rameters and market risk premia by constructing an Equivalent Martingale Measure using Girsanov’s theorem and a normalized Esscher transform. This condition provides a rigorous foundation for arbitrage-free pricing in models with diffusion-dependent jumps.

Effects Of A Group Contingency Arrangement Of Synchronous Reinforcement On Disruptive Behavior In Elementary Classes, Gabriela Gomes Jan 2026

Effects Of A Group Contingency Arrangement Of Synchronous Reinforcement On Disruptive Behavior In Elementary Classes, Gabriela Gomes

LSU Master's Theses

Synchronous schedules of reinforcement are a type of schedule of covarion in which the onset and offset of the response are aligned with the onset and offset of the reinforcer. In this study, we used multiple baseline across classes and reversal designs to determine the effects of a synchronous reinforcement schedule, arranged as a group contingency, on disruptive classroom behavior and time spent following rules during independent work periods in three elementary classrooms: 2 first grade and 1 fourth grade. Additionally, we compared the effects of a synchronous reinforcement schedule with a continuous noncontingent schedule in the fourth-grade classroom. The …

Improving Stem Assessments: Strategies For Increasing The Accessibility And Adoption Of Two-Stage Exams, Kristina Callaghan Jan 2026

Improving Stem Assessments: Strategies For Increasing The Accessibility And Adoption Of Two-Stage Exams, Kristina Callaghan

LSU Doctoral Dissertations

Over three decades of research have shown that students taught using active learning strategies achieve better learning outcomes compared to those taught using traditional methods. Two-stage exams, which pair a traditional exam with a group component, are an increasingly popular method for incorporating active learning within the assessment component of a course. Previous studies have shown this assessment strategy provides a variety of benefits for students, including increased engagement and collaboration, immediate feedback, and potentially increased content retention. However, the unique circumstances of each instructor can pose a non-trivial barrier to the implementation of two-stage exams. In this thesis, we …

Applications For The Quasi-Atomic Orbital And Constrained Density Functional Theory Methods On Catalytic Reactions, Alvaro David Loaiza Orduz Jan 2026

Applications For The Quasi-Atomic Orbital And Constrained Density Functional Theory Methods On Catalytic Reactions, Alvaro David Loaiza Orduz

LSU Doctoral Dissertations

Selective activation of C–O, C–H, and C–C bonds underpins biomass upgrading, alkane functionalization, and CO₂ conversion. Despite their importance, the electronic factors governing catalytic performance remain incompletely understood, and many industrial processes still rely on empirical trends or material-specific observations. This dissertation addresses this gap by applying density functional theory (DFT), thermodynamic decomposition, and electronic-structure analysis to identify unifying principles of reactivity across transition-metal phosphides, vanadate oxides, copper-based electrocatalysts, and mixed IrO₂–RuO₂ layers. This work examines how charge transfer, orbital localization, and ligand-induced perturbations control reaction pathways in diverse catalytic systems. C–O bond scission in 2-methyltetrahydrofuran (MTHF) and methanol was …

Measurement Of 18f(Alpha,P)21ne With The Array For Nuclear Astrophysics And Structure With Exotic Nuclei (Anasen), Keilah S. Davis

LSU Doctoral Dissertations

Certain (α,p) reactions on proton-rich nuclei are among the most important nuclear reactions occurring during Type I X-ray bursts, as well as being impactful in stellar explosions during the Asymptotic Giant Branch (AGB) phase and on accreting white dwarfs (WD). However, large uncertainties remain for reaction rates on some radioactive nuclei due to the lack of direct measurements. The Array for Nuclear Astrophysics and Structure with Exotic Nuclei (ANASEN) is a gas target and charged-particle detector designed for direct measurements of (α,p) reactions. ANASEN was redesigned with two hexagonal barrels of 100-µm-thick silicon strip surrounding the beam axis over a …

Metacommunity Coupled Epidemiological And Biophysical Modeling Of An Emergent Coral Disease, Benjamin Holmes Farmer Jan 2026

Metacommunity Coupled Epidemiological And Biophysical Modeling Of An Emergent Coral Disease, Benjamin Holmes Farmer

LSU Doctoral Dissertations

Emerging infectious diseases pose imminent risk to the marine realm and coral reefs in particular. Since its emergence in 2014, stony coral tissue loss disease (SCTLD) has dramatically reduced living coral cover in Florida and charted a similar course in the Caribbean. SCTLD is by far the most severe coral disease in history and has driven highly susceptible species to local extinction, yet the mechanisms driving the regional epizootic are not well understood. Here, we developed reef-scale parameterizations of disease spread using model sites in the lower Florida Keys, developed extensive metacommunity habitat maps for the US Caribbean, and then …

Legacy Phosphorus Dynamics In Subtropical River Sediments: Impacts Of Dredging And Water Column Aeration Status, Lee Potter, John R. White Jan 2026

Legacy Phosphorus Dynamics In Subtropical River Sediments: Impacts Of Dredging And Water Column Aeration Status, Lee Potter, John R. White

Faculty Publications

Excessive loading of phosphorus (P) in coastal systems has been a growing concern for watershed managers due to the link with harmful algal blooms. In particular, legacy P creates a persistent challenge for eutrophication management in a range of aquatic systems, including wetlands, lakes, and estuaries, as a source of indirect, internal P loading. Following reductions in external P loads, internal sediment sources have been known to release bioavailable P back into the water column, undermining nutrient restoration goals. This study investigates the flux dynamics and longevity of sediment legacy P in three subtropical rivers—Amite, Tangipahoa, and Tickfaw—draining into the …

Increasing Wave Heights In The Gulf Of Mexico Driven By Swell Waves, Jesbin George, Matthew Hiatt, Clinton S. Willson

Faculty Publications

This study analyzes the climatology, spatial and temporal trends of wind speeds and significant wave height (Hs) of combined wind-seas and swells and Hs of separated swells and wind-seas on annual and seasonal scales in the Gulf of Mexico (GoM) using 50 years of atmospheric reanalysis data. The Hs data showed strong agreement with in-situ measurements, with minimal bias (+/-< 0.08 m) and high correlation (r > 0.9) across both deep and shallow regions, although a slight underestimation is noted for wind speed data. Wind speeds showed seasonal variability in the GoM, though they did not exhibit significant long-term increases, except for a notable decrease (~ -1.0 …

Rosenwald Rural School Libraries, Suzanne Marie Stauffer Jan 2026

Rosenwald Rural School Libraries, Suzanne Marie Stauffer

Faculty Publications

The Rosenwald Rural School Libraries Program was created as an adjunct to the Rosenwald Rural Schools Program, which funded the construction of 4,977 rural Black school buildings in fifteen Southern states, 395 of them in Louisiana. However, it soon became apparent that providing textbooks was not enough to promote literacy and develop self-directed reading among students. The officers and agents of the Fund realized fairly early in the Rural Schools Program that there was a want of reading materials in the South in general. Beginning in 1927, the Rosenwald Fund began providing collections of graded fiction and non-fiction books to …

Archicrochet: Failure Localization In Stitch-Based Structures, Skylar Vollmer, Farzaneh Oghazian Jan 2026

Archicrochet: Failure Localization In Stitch-Based Structures, Skylar Vollmer, Farzaneh Oghazian

Distinguished Undergraduate Researcher Program

ArchiCrochet investigates crochet as a discrete, node-and-stitch-based structural system for architectural applications, integrating traditional handcraft with parametric design methodologies. Through comparative analysis of knit and crochet textiles, the research identifies crochet’s capacity for localized failure, distributed load paths, and structural redundancy. These properties are explored through a combination of parametric modeling in Grasshopper and full-scale physical construction, allowing digital structural logic to be tested against real material behavior.

Using a bottom-up approach to study stitch behavior and a top-down approach to generate overall form, the project translates simplified computational patterns into manually fabricated textile structures. The research culminates in a …

Will It Tear? Creating A Collegiate Athlete Cutting Mechanics Grading Process, Abigail Savoy, Matthew Morgan, Nicholas Totaro Jan 2026

Will It Tear? Creating A Collegiate Athlete Cutting Mechanics Grading Process, Abigail Savoy, Matthew Morgan, Nicholas Totaro

Distinguished Undergraduate Researcher Program

Collegiate athletes push their bodies to compete at the top level of their sport. Through 5 years, collegiate athletes had 729 ACL tears. To aid in training and the reduction of injury risk, there are several procedures for grading the ability of an athlete to make a cut or change-of direction motion. Through this research project, we defined a procedure for analyzing motion capture video and data of the cutting mechanics of collegiate athletes. This was done to identify which athletes have a higher or lower risk of an ACL injury by comparing knee valgus and other biomechanical indicators on …

Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond Jan 2026

Characterizing The Role Off The Sp1/Klf Transcription Factor Huckebein In The Drosophila Melanogaster Ventral Nerve Cord, Benjamin Almond

Distinguished Undergraduate Researcher Program

Over the course of embryonic development, the ectodermal cell layer gives rise to a vast array of neurons and glia patterned across the central nervous system (CNS). Neurulation and specification is achieved in the ectoderm through temporospatial patterns of transcription factor (TF) expression, many of which are conserved across evolutionary history. These conserved regulatory motifs allow the use of Drosophila melanogaster to study the mechanisms of neurodevelopment across the animal kingdom. The huckebein (hkb) gene encodes a conserved SP1/KLF TF known to play important roles in cell cycle regulation, tissue morphogenesis during tubular organ development, and gut specification in Drosophila. …

Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal Jan 2026

Physiological Leptin Replacement Does Not Reverse Metabolic Adaptations To Starvation In Sprague Dawley Rats, Sydney Junot, Layla Deprimo, Camille Meaux, Arline Narez, David Mcdougal

Distinguished Undergraduate Researcher Program

Historically, low insulin levels were the signaling event considered responsible for metabolic adaptations to starvation, such as increased sympathetic outflow and increased serum levels of ketones, glucagon, and free fatty acids. Leptin, a hormone produced by adipose tissue, is known to decrease in response to caloric restriction. Recent work in the field suggested that leptin infusion in the final hours of a 48-hour fast reversed all metabolic adaptations to starvation, thus raising questions about an underappreciated role of leptin in the starvation response. This study tested whether physiological leptin replacement, maintaining fed plasma leptin concentrations, during a 72-hour fast in …

Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman Jan 2026

Passing In Plain Sight: Visibility, Activism, And Identity, Rei Zimmerman

Distinguished Undergraduate Researcher Program

The act of passing would seem to be the opposite of activism because it is an act meant to avoid detection. While the language of passing is, itself, problematic, African-descended people passing as white might be read as attempting to capitulate to a racial binary. Similarly, trans people passing as cis or cishet might be read as attempting to capitulate to the gender binary rather than challenging it. But this paper explores the potential for reading passing as a surprising act of activism that foregrounds resistance, resilience, and solidarity rather than disappearance. I focus on Leslie Feinberg’s groundbreaking trans novel …

Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes Jan 2026

Developing A Comparative Framework For Organic Matter Loss Using Standardized Soils To Mimic Urbanized Areas, Madison Woodson, Michael (M.P.) Hayes

Distinguished Undergraduate Researcher Program

Rapid urbanization is an ongoing challenge to the natural ecosystem across Louisiana as the state invests in development to accommodate the challenges of flooding in nearby towns and cities. Across Louisiana waterways, flooding from urban developments along with coastal subsidence and relative sea level rise increase the transport of complex organic matter into local water channels. These events lead to higher concentrations of nutrients, specifically bioavailable carbon which can be lost from breakdown of soil organic matter in water. To better understand and predict organic matter transportation due to flooding events caused by urbanization, we studied the availability of organic …

Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim Jan 2026

Impacts Of Real Microplastic Leachates On The Development And Behavior Of Developing Zebrafish (Danio Rerio), Emma Tsai, Melanie Wilson, Mohamed Ateia, Ahmed Abdelmoneim

Distinguished Undergraduate Researcher Program

Plastic pollution in aquatic environments has increased, raising concerns about the toxicity of microplastics (MPs) and their additives to developing organisms. Additives from the MPs can desorb into the surrounding environment, generating leachates that may impact early development. This study evaluated the effects of early developmental exposure to MP leachates on early developing zebrafish (Danio rerio), quantifying effects on larval survival, development, activity, and behavioral responses to acute stressors. MPs—acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyamide 66 (PA66), and reinforced glass fiber (MIX)—were processed into particles (< 500 µm) and incubated in embryo media for 24 hours under UV-C, 35 °C, and agitation to generate leachates. Zebrafish embryos were exposed from 6 to 120 hours post-fertilization (hpf) to varying leachate dilutions (corresponding to 0.063 to 10,000 mg MPs/L). At 120 hpf, larvae were assessed for survival, prevalence of morphological defects, overall growth, baseline activity, and behavioral responses to acoustic, visual, and peripheral irritant stressors. MIX leachate significantly increased mortality, while PET leachate exposure reduced growth. No significant morphological defects were observed across treatments. ABS, PA66, and PET leachates altered larval activity and behavioral stress responses. These preliminary findings suggest that MP leachates pose varying developmental and behavioral risks to developing organisms at critical exposure concentrations. Understanding these risks is crucial for assessing the environmental impact of MPs pollution and informing regulatory policies.

Anxiety Disorders Do Not Modulate Performance Monitoring During Visuomotor Learning, Olivia Perry, Leo Barzi, Kaylie Grimm, Leah Charles, Christopher Hill Jan 2026

Anxiety Disorders Do Not Modulate Performance Monitoring During Visuomotor Learning, Olivia Perry, Leo Barzi, Kaylie Grimm, Leah Charles, Christopher Hill

Distinguished Undergraduate Researcher Program

Humans experience different levels of anxiety throughout their daily lives. Some individuals even experience chronic, unprovoked anxiety that leads to a diagnosis of a psychological disorder known as generalized anxiety disorder. Many neurological diseases develop anxiety as a comorbidity and hinder therapeutic interventions. However, we don’t understand how anxiety disorders may affect the development and learning of new motor skills. Thus, the purpose of this study is to evaluate how different levels of anxiety may affect your ability to learn a new skill. We recruited physically healthy, right-handed young adults with and without a diagnosis of an anxiety disorder. Participants …

Bayou Bride: Combining Alligator Leather And Digital Textile Printing In Bridalwear, Martha Rigney, Casey Stannard

Distinguished Undergraduate Researcher Program

Alligator leather is attractive to luxury consumers because of its unique texture and beauty. However, due to the shape of alligator hides, differing scale patterns, and the hardness of the leather, it is less appealing for usage in apparel. One strategy to retain the visual appeal of alligator leather while improving comfort and versatility is to create photo-realistic digitally printed “alligator” textiles alongside real leather. Discovering new ways to use alligators is crucial to the alligator industry, which is experiencing a price slump. This project focused on the bridal market; the utilization of sublimation dye printing allowed me to experiment …
