A Multivariate Statistical Approach For Mineral Geographic Provenance Determination Using Laser-Induced Breakdown Spectroscopy And Electron Microprobe Chemical Data: A Case Study Of Copper-Bearing Tourmalines, Barbara L. Dutrow, Nancy J. Mcmillan, Darrell J. Henry

Faculty Publications

The geographic provenance of minerals provides key insights into a range of geologic problems, including the source of gem materials. The tourmaline supergroup is unparalleled in its ability to record and preserve extensive chemical signatures of its formational environment. To evaluate the likelihood that tourmalines of similar compositions from separate geographic localities could be differentiated, a multivariate statistical approach has been utilized on two complementary data sets. These chemical analytical data sets of copper-bearing "Paraiba"tourmaline include data sets acquired with Laser Induced Breakdown Spectroscopy (LIBS) and electron microprobe analysis (EMPA). Fifty-four samples of copper-bearing tourmalines from known source locations from …

Pressure And Rate Transient Analyses For Plume Characterization And Storage Capacity Estimation Of Co2 Storage Projects, Mohamed Elnoby Mokhtar Abdelaal

LSU Doctoral Dissertations

Reservoir characterization is a key factor for effective management of commercial-scale Geologic CO2 Storage (GCS) projects. Pressure/rate transient analyses (PTA/RTA) have evolved as reliable tools for assessing hydrocarbon and GCS reservoirs. Injection rate and pressure data are routinely measured as a part of GCS projects’ surveillance, or during transient well testing. The data contain valuable information about the subsurface that can be extracted. The extracted information enables the operator to evaluate the effectiveness of injection operations, and to make remedial/corrective interventions. In this current work, different analytical and numerical techniques are presented to characterize, assess, and maximize the economic and …

Copper-Based Electrocatalysts For Electrochemical Reduction Of Co2 To C2 Products, Monsuru Olatunji Dauda

LSU Master's Theses

The electrochemical reduction of CO₂ using copper-based electrocatalysts has emerged as a promising approach for sustainable chemical production, offering a pathway to mitigate the rising atmospheric CO₂ levels while generating valuable fuels and chemicals. However, the selectivity and efficiency of copper-based catalysts towards specific C₂ products remain a major challenge, hindering their commercial viability. This thesis focuses on the development, characterization, and mechanistic understanding of three promising electrocatalyst systems for multi-carbon product generation from CO₂ reduction: copper-phosphide (Cu-P), copper-tin (Cu-Sn), and copper selenide (Cu₂Se). A comprehensive investigation of the electrocatalysts was conducted using advanced …

The Relationship Between Communicative And Social Deficits And Challenging Behavior In Angelman Syndrome, Cassie Chanel Feck

LSU Doctoral Dissertations

Angelman Syndrome (AS) is a low-incidence neurodevelopmental disorder characterized by deficits in speech, motor, and social development as well as related differences in challenging behavior, seizures, and sleep issues. AS has a known genetic etiology and research conducted with this population has overwhelmingly focused on exploring the genetic and biological underpinnings of the disorder (e.g., applied gene therapies). At present, far less research on supporting the social, communicative, and behavioral needs of this population and how these specific deficits contribute to the individual’s overall functioning. The goals of this study were to characterize the use of Augmentative and Alternative Communication …

Birefringence Tests Of Gravity With Multimessenger Binaries, Macarena Lagos, Leah Jenks, Maximiliano Isi, Kenta Hotokezaka, Brian D. Metzger, Eric Burns, Will M. Farr, Scott Perkins, Kaze W.K. Wong, Nicolás Yunes

Faculty Publications

Extensions to general relativity allow the polarization of gravitational waves (GW) from astrophysical sources to suffer from amplitude and velocity birefringence, which respectively induce changes in the ellipticity and orientation of the polarization tensor. We introduce a multimessenger approach to test this polarization behavior of GWs during their cosmological propagation using binary sources, for which the initial polarization is determined by the inclination and orientation angles of the orbital angular momentum vector with respect to the line of sight. In particular, we use spatially resolved radio imaging of the jet from a binary neutron star (BNS) merger to constrain the …

Desire Paths In The Information Landscape, Victoria Van Hyning, Mason A. Jones, Travis Wagner

Journal of Critical Digital Librarianship

Libraries and archives serve so many different users who come to information institutions with various perspectives, needs, experiences, and desires around accessing physical or digital collections. While our users may find what they are looking for immediately, many have to beat their own paths through complex systems and metadata that doesn’t align with their needs. Their search strategies may leave digital “desire paths”–alternative routes through the information landscape that can show us how to better meet their needs. This article covers three scenarios where users’ desire paths can be seen or where gaps around user experience can be better addressed. …

Examining The Relations Between Number Of Opportunities To Self-Monitor And Self-Monitoring On-Task Or Accuracy In Children, Alison Ruby

LSU Doctoral Dissertations

Difficulties in academic achievement have been linked to adverse outcomes such as increased problem behavior and delays in development (Hinshaw, 1992). Early education should include training to self-monitor, as self-monitoring can improve academic performance and has a wide range of uses (Harris et al., 2005). Previous literature typically uses frequent self-monitoring opportunities ranging from every 30 seconds to 1 minute. The purpose of this study was to identify the effects of the number of self-monitoring opportunities when self-monitoring on-task behavior and self-monitoring accuracy of task completion, on-task behavior, disruptions, and accuracy of self-monitoring (types of errors) and determine the preferences …

The Effects Of High-Pressure Annealing On Magnetostructural Transitions And Magnetoresponsive Properties In Stoichiometric Mncoge, Tej Poudel Chhetri, Jing Han Chen, David P. Young, Igor Dubenko, Saikat Talapatra, Naushad Ali, Shane Stadler

Faculty Publications

In this study, phase transitions (structural and magnetic) and associated magnetocaloric properties of stoichiometric MnCoGe have been investigated as a function of annealing pressure. Metastable phases were generated by annealing at 800 ° C followed by rapid cooling under pressures up to 6.0 GPa. The x-ray diffraction results reveal that the crystal cell volume of the metastable phases continuously decreases with increasing thermal processing pressure, leading to a decrease in the structural transition temperature. The magnetic and structural transitions merge and form a first-order magnetostructural transition between the ferromagnetic orthorhombic and paramagnetic hexagonal phases over a broad temperature range ( …

Lignocellulosic Nanomaterial In An Oil-In-Water Emulsion Fluid System With Or Without An Emulsifier Sucrose Ester, Meen Sung Koo, Mohammad Shayan, Ragab Abouzeid, Qinglin Wu

Faculty Publications

The effect of lignocellulosic nanomaterial (LCNM) including lignin-containing cellulose nanofibers (LCNFs) and cellulose nanofibers (CNFs) on a diesel oil-in-water (O/W) emulsion was investigated with and without the emulsifier sucrose ester (SE). The O/W (65:35) emulsions were successfully stabilized by LCNFs with two lignin levels, while emulsions with CNFs exhibited large fiber flocs in the external phase only. High-lignin-content LCNFs led to a more uniform oil droplet size without formation of fiber flocs, whereas low-lignin-content LCNFs in emulsion revealed a wide size distribution of the oil droplets with intensive fiber flocs. The presence of SE significantly enhanced the stability of LCNM …

Mitochondria have diverse functions critical to whole-body metabolic homeostasis. Endurance training alters mitochondrial activity, but systematic characterization of these adaptations is lacking. Here, the Molecular Transducers of Physical Activity Consortium mapped the temporal, multi-omic changes in mitochondrial analytes across 19 tissues in male and female rats trained for 1, 2, 4, or 8 weeks. Training elicited substantial changes in the adrenal gland, brown adipose, colon, heart, and skeletal muscle. The colon showed non-linear response dynamics, whereas mitochondrial pathways were downregulated in brown adipose and adrenal tissues. Protein acetylation increased in the liver, with a shift in lipid metabolism, whereas oxidative …

A Flow-Curvature-Based Model For Channel Meandering In Tidal Marshes, Giulio Mariotti, Alvise Finotello

Faculty Publications

Channel meandering is ubiquitous in tidal marshes, yet it is either omitted or weakly implemented in morphodynamic models. Here we propose a novel numerical method to simulate channel meandering in tidal marshes on a Cartesian grid. The method calculates a first-order flow by considering the balance between pressure gradient and bed friction. To account for flow momentum shift toward meander outer banks, the flow is empirically modified. Unlike previous simplified methods that relied on the curvature of the bank, this modification is based on the curvature of the flow, making the model suitable for use in dendritic channel networks. The …

Faculty Publications

Targeted agents and immunotherapies have revolutionized cancer treatment, offering promising options for various cancer types. Unlike traditional therapies the principle of “more is better” is not always applicable to these new therapies due to their unique biomedical mechanisms. As a result, various phase I–II clinical trial designs have been proposed to identify the optimal biological dose that maximizes the therapeutic effect of targeted therapies and immunotherapies by jointly monitoring both efficacy and toxicity outcomes. This review article examines several innovative phase I–II clinical trial designs that utilize accumulated efficacy and toxicity outcomes to adaptively determine doses for subsequent patients and …

Caloric restriction (CR) modifies lifespan and aging biology in animal models. The Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy (CALERIE™) 2 trial tested translation of these findings to humans. CALERIE™ randomized healthy, nonobese men and premenopausal women (age 21–50y; BMI 22.0–27.9 kg/m2), to 25% CR or ad-libitum (AL) control (2:1) for 2 years. Prior analyses of CALERIE™ participants' blood chemistries, immunology, and epigenetic data suggest the 2-year CR intervention slowed biological aging. Here, we extend these analyses to test effects of CR on telomere length (TL) attrition. TL was quantified in blood samples collected at baseline, 12-, …

We report the discovery of X-ray polarization from the X-ray-bright filament G0.13-0.11 in the Galactic center (GC) region. This filament features a bright, hard X-ray source that is most plausibly a pulsar wind nebula (PWN) and an extended and structured diffuse component. Combining the polarization signal from IXPE with the imaging/spectroscopic data from Chandra, we find that X-ray emission of G0.13-0.11 is highly polarized PD = 57(±18)% in the 3-6 keV band, while the polarization angle is PA = 21° ± 9). This high degree of polarization proves the synchrotron origin of the X-ray emission from G0.13-0.11. In turn, the …

Faculty Publications

Three novel binary barium arsenides, Ba3As4, Ba5As4, and Ba16As11, were synthesized and their crystal and electronic structures were investigated. Structural data collected via the single-crystal X-ray diffraction method indicate that the anionic substructures of all three novel compounds are composed of structural motifs based on the homoatomic As–As contacts, with [As2]⁴⁻ dimers found in Ba5As4 and Ba16As11, and an [As4]⁶⁻ tetramer found in Ba3As4. Ba3As4 and Ba5As4 crystallize in the orthorhombic crystal system—with the non-centrosymmetric space group Fdd2 (a = 15.3680(20) Å, b = 18.7550(30) Å, c = 6.2816(10) Å) for the former, and the centrosymmetric space group …

The Role Of Ice And Latitude-Dependent Mantling On Boulder Distributions Across The Martian Northern Lowlands, A. L. Cohen-Zada, D. R. Hood, R. C. Ewing, S. Karunatillake

Faculty Publications

Boulders are ubiquitous on rocky planets and provide valuable information about planetary processes. The abundance, size, and distribution of boulders offer insights into the primary processes that form them and the secondary processes that modify their position and size. However, the roles of varying environmental processes, including cryospheric processes, are poorly known. In this study, we analyze over 20 million boulders in the northern lowlands of Mars (50–70°N) to evaluate their distribution and identify environmental factors that might influence their clustering. We used spatial statistics to quantify the degree of boulder clustering across the northern plains. We found two latitudinal …

Leveraging Designed Simulations And Machine Learning To Develop A Surrogate Model For Optimizing The Gas–Downhole Water Sink–Assisted Gravity Drainage (Gdws-Agd) Process To Improve Clean Oil Production, Watheq J. Al-Mudhafar, Dandina N. Rao, Andrew K. Wojtanowicz

Faculty Publications

The Gas and Downhole Water Sink–Assisted Gravity Drainage (GDWS-AGD) process addresses gas flooding limitations in reservoirs surrounded by infinite-acting aquifers, particularly water coning. The GDWS-AGD technique reduces water cut in oil production wells, improves gas injectivity, and optimizes oil recovery, especially in reservoirs with high water coning. The GDWS-AGD process installs two 7-inch production casings bilaterally. Then, two 2-3/8-inch horizontal tubings are completed. One tubing produces oil above the oil–water contact (OWC) area, while the other drains water below it. A hydraulic packer in the casing separates the two completions. The water sink completion uses a submersible pump to prevent …

Comparing Editorial And Artificially Generated Fingerings: A Case Study, Lixi Qin

LSU Doctoral Dissertations

Fingering is crucial for piano performance. Unlike other instruments with relatively fixed fingerings, keyboard instruments offer countless fingering combinations. As musical styles have evolved, so too have the instruments themselves, resulting in a rich history of diverse fingering systems, which sometimes conflict with one another. Moreover, due to individual differences in hand shape and size, the fingering advice from editors or teachers may not be universally applicable, and there is a lack of an objective, unified standard for validating these recommendations.

For students who do not fully understand fingering principles and have not been exposed to a wide range of …
