Spectroscopic Modeling Of Luminous Transients Powered By H-Rich And He-Rich Circumstellar Interaction, Gururaj A. Wagle, Emmanouil Chatzopoulos, Michael J. Baer Jan 2025

Spectroscopic Modeling Of Luminous Transients Powered By H-Rich And He-Rich Circumstellar Interaction, Gururaj A. Wagle, Emmanouil Chatzopoulos, Michael J. Baer

Faculty Publications

In this study, we perform detailed spectroscopic modeling to analyze the interaction of circumstellar material (CSM) with ejecta in both hydrogen-rich and hydrogen-poor superluminous supernovae (SLSNe), by systematically varying properties such as the CSM density, composition, and geometry to explore their effects on spectral lines and light-curve evolution. Using advanced radiative transfer simulations with the new, open-source SuperLite code to generate synthetic spectra, we identify key spectroscopic indicators of CSM characteristics. Our findings demonstrate that spectral lines of hydrogen and helium exhibit significant variations due to differences in CSM mass and composition. In hydrogen-rich Type II SLSNe, we observe pronounced …

Profinite Properties Of Algebraically Clean Graphs Of Free Groups, Kasia Jankiewicz, Kevin Schreve Jan 2025

Profinite Properties Of Algebraically Clean Graphs Of Free Groups, Kasia Jankiewicz, Kevin Schreve

Faculty Publications

We prove that for every prime p algebraically clean graphs of groups are virtually residually p-finite and cohomologically p-complete. We also prove that they are cohomologically good. We apply this to certain 2-dimensional Artin groups.

Reservoir Engineering For Co₂ Storage: Fundamental & Practical Aspects, Mehdi Zeidouni Jan 2025

Reservoir Engineering For Co₂ Storage: Fundamental & Practical Aspects, Mehdi Zeidouni

LSU Faculty-Published Books

Bridging the gap between carbon storage theory and petroleum engineering practice.

This comprehensive guide distills nearly two decades of research and teaching into a clear, application-focused resource on geological CO2 storage modeling, carbon capture and storage modeling (CCS modeling), and CO2 reservoir modeling—all tailored specifically for petroleum engineers.

While GCS modeling has historically been driven by physics, mathematics, and hydrogeology, petroleum engineering CO2 modeling often requires a different approach. This book translates complex, multidisciplinary CO2 geological modeling techniques into a unified, petroleum engineer–friendly framework. Whether your focus is CO2 sequestration engineering, enhanced oil recovery CO2 modeling, or transitioning from oil …

Hydrogen And Deuterium Tunneling In Niobium, Abdulaziz Abogoda, W. A. Shelton, I. Vekhter, J. A. Sauls Jan 2025

Hydrogen And Deuterium Tunneling In Niobium, Abdulaziz Abogoda, W. A. Shelton, I. Vekhter, J. A. Sauls

Faculty Publications

We use density functional methods to identify the atomic configurations of H and D atoms trapped by O impurities embedded in bulk Nb. The O atoms are located at the octahedral position in the Nb body-centered cubic (BCC) lattice, and H (D) atoms tunnel between two degenerate tetrahedral sites separated by a mirror plane. Using nudged elastic band (NEB) methods, we calculate the double-well potential for O-H and O-D impurities and the wave functions and tunnel splittings for H and D atoms. Our results agree with those obtained from analysis of heat capacity and neutron scattering measurements on Nb with …


The Intelligence Debate: Bilingualism Vs Monolingualism - A Systematic Review, Muhammad Ayyaz Jan 2025

The Intelligence Debate: Bilingualism Vs Monolingualism - A Systematic Review, Muhammad Ayyaz

Communication Sciences & Disorders Graduate Student Work

The primary aim of the study is to find out whether bilinguals are more intelligent than monolinguals. The study synthesized relevant literature on the relationship between intelligence and bilingualism with regard to Raven's matrices, a widely recognized tool to assess abstract reasoning. Given the increasing prevalence of bilingualism because of migration and globalization, gaining insight into its cognitive influence is crucial (Surrain & Luk, 2017). Fluid intelligence (gf), crystallized intelligence (gc), and general intelligence (g) are included in this study. Across multiple databases, including ERIC, PsycINFO, and Web of Science, the study involved a comprehensive literature review of the studies …

Chemotherapy treatment-related side effects are common and increase the risk of suboptimal outcomes. Exercise interventions during cancer treatment improve self-reported physical functioning, fatigue, anxiety, and depression, but it is unclear whether these interventions improve important clinical outcomes, such as chemotherapy relative dose intensity. The National Cancer Institute funded the Exercise and Nutrition to Improve Cancer Treatment-Related Outcomes (ENICTO) Consortium to address this knowledge gap. This article describes the mechanisms hypothesized to underpin intervention effects on clinically relevant treatment outcomes, briefly outlines each project’s distinct research aims, summarizes the scope and organizational structure of ENICTO, and provides an overview of the …

We examined global records of accessible natural history voucher collections (with publicly available data and reliable locality data) for terrestrial and freshwater vascular plants, fungi, freshwater fishes, birds, mammals, and herpetofauna (amphibians and reptiles) and highlight areas of the world that would be considered undersampled and sometimes called ‘unexplored’ (i.e., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. We also question what ‘unexplored’ may mean in these contexts and explain how replacing the term in favor of more nuanced phrasing (e.g., ‘biodiversity blindspots,’ which emphasizes the lack of publicly available data about specimens) can …


Targeting Bacterial Transcription Factors For Infection Control: Opportunities And Challenges, Ahmed Al-Tohamy, Anne Grove Jan 2025

Targeting Bacterial Transcription Factors For Infection Control: Opportunities And Challenges, Ahmed Al-Tohamy, Anne Grove

Faculty Publications

The rising threat of antibiotic resistance in pathogenic bacteria emphasizes the need for new therapeutic strategies. This review focuses on bacterial transcription factors (TFs), which play crucial roles in bacterial pathogenesis. We discuss the regulatory roles of these factors through examples, and we outline potential therapeutic strategies targeting bacterial TFs. Specifically, we discuss the use of small molecules to interfere with TF function and the development of transcription factor decoys, oligonucleotides that compete with promoters for TF binding. We also cover peptides that target the interaction between the bacterial TF and other factors, such as RNA polymerase, and the targeting …

All-Electron Molecular Tunnel Ionization Based On The Weak-Field Asymptotic Theory In The Integral Representation, Imam S. Wahyutama, Denawakage D. Jayasinghe, François Mauger, Kenneth Lopata, Kenneth J. Schafer Jan 2025

All-Electron Molecular Tunnel Ionization Based On The Weak-Field Asymptotic Theory In The Integral Representation, Imam S. Wahyutama, Denawakage D. Jayasinghe, François Mauger, Kenneth Lopata, Kenneth J. Schafer

Faculty Publications

Tunnel ionization (TI) underlies many important ultrafast processes, such as high-harmonic generation and strong-field ionization. Among the existing theories for TI, many-electron weak-field asymptotic theory (ME-WFAT) is by design capable of accurately treating many-electron effects in TI. An earlier version of ME-WFAT relied on an accurate representation of the asymptotic tail of the orbitals, which hindered its implementation in Gaussian-basis-set-based quantum chemistry programs. In this work, we reformulate ME-WFAT in the integral representation, which makes the quality of the asymptotic tail much less critical, hence greatly facilitating its implementation in standard quantum chemistry packages. The integral reformulation introduced here is …

Maximum Spread Of Ks,T-Minor-Free Graphs, William Linz, Linyuan Lu, Zhiyu Wang Jan 2025

Maximum Spread Of Ks,T-Minor-Free Graphs, William Linz, Linyuan Lu, Zhiyu Wang

Faculty Publications

The spread of a graph G is the difference between the largest and smallest eigenvalue of the adjacency matrix of G. In this paper, we consider the family of graphs which contain no Ks,t-minor. We show that for any t ≥ s ≥ 2 and sufficiently large n, there is an integer ξt such that the extremal n-vertex Ks,t-minor-free graph attaining the maximum spread is the graph obtained by joining a graph L on (s −1) vertices to the disjoint union of (Formula Presented) copies of Kt and (Formula Presented) isolated vertices. Furthermore, we give an explicit formula for ξt …
