Multiphoton Quantum Van Cittert-Zernike Theorem, Chenglong You, Ashe Miller, Roberto De J. León-Montiel, Omar S. Magaña-Loaiza

Faculty Publications

Recent progress on quantum state engineering has enabled the preparation of quantum photonic systems comprising multiple interacting particles. Interestingly, multiphoton quantum systems can host many complex forms of interference and scattering processes that are essential to perform operations that are intractable on classical systems. Unfortunately, the quantum coherence properties of multiphoton systems degrade upon propagation leading to undesired quantum-to-classical transitions. Furthermore, the manipulation of multiphoton quantum systems requires nonlinear interactions at the few-photon level. Here, we introduce the quantum van Cittert-Zernike theorem to describe the scattering and interference effects of propagating multiphoton systems. This fundamental theorem demonstrates that the quantum …

Digital Archives: How Western Newspapers Frame Our Remembrance Of The Gezi Park Protest, Nihar Sreepada, Ahmet Aksoy

Faculty Publications

We analyze the coverage of the Gezi Park protests by two major Western newspapers - The New York Times and The Guardian - through the lens of media framing, rhetoric, and collective memory. We argue that these digital archives frame Turkey's Gezi Park protests as a challenge to an authoritarian government by promoting the themes of unrest as a conflict of ideologies, oppression of citizens, and the park as a site of memory. In a concluding section, we focus on the significance of digital archives as repositories of collective memory and the role of media framing in shaping these reconstructions …

Bearded Or Smooth? Awns Improve Yield When Wheat Experiences Heat Stress During Grain Fill In The Southeastern United States, Noah Dewitt, Jeanette Lyerly, Mohammed Guedira, James B. Holland, J. Paul Murphy, Brian P. Ward, Richard E. Boyles, Mohamed Mergoum, Md Ali Babar, Ehsan Shakiba, Russel Sutton, Amir Ibrahim, Vijay Tiwari, Nicholas Santantonio, David A. Van Sanford, Kimberly Howell, Jared H. Smith, Stephen A. Harrison, Gina Brown-Guedira

Faculty Publications

The presence or absence of awns-whether wheat heads are 'bearded' or 'smooth' - is the most visible phenotype distinguishing wheat cultivars. Previous studies suggest that awns may improve yields in heat or water-stressed environments, but the exact contribution of awns to yield differences remains unclear. Here we leverage historical phenotypic, genotypic, and climate data for wheat (Triticum aestivum) to estimate the yield effects of awns under different environmental conditions over a 12-year period in the southeastern USA. Lines were classified as awned or awnless based on sequence data, and observed heading dates were used to associate grain fill periods of …

Chiral Fermion Anomaly As A Memory Effect, Adrián Del Río, Ivan Agullo

Faculty Publications

We study the nonconservation of the chiral charge of Dirac fields between past and future null infinity due to the Adler-Bell-Jackiw chiral anomaly. In previous investigations [A. del Rio, Phys. Rev. D 104, 065012 (2021)PRVDAQ2470-001010.1103/PhysRevD.104.065012], we found that this charge fails to be conserved if electromagnetic sources in the bulk emit circularly polarized radiation. In this article, we unravel yet another contribution coming from the nonzero, infrared "soft"charges of the external, electromagnetic field. This new contribution can be interpreted as another manifestation of the ordinary memory effect produced by transitions between different infrared sectors of Maxwell theory, but now on …

A Study Of Tissue-Specific Rho Signaling Activation During Tubular Organ Formation In Drosophila, Charlotte Jean-Louise Adams

LSU Master's Theses

Several organs within the human body are tubular in structure. In the event of a malfunction in the development of these tubular structures, maladies like spina bifida, anencephaly, and several other defects can arise. To understand the mechanisms of tubular organ formation, we use the Drosophila embryonic salivary gland (SG) as a model. During embryogenesis, SG cells undergo a series of cell shape changes, like apical constriction, to accommodate the developing gland. Apical constriction is regulated in part by the signal of the secreted ligand Folded gastrulation (Fog) and its G protein-coupled receptor (GPCR) at the cell membrane, which leads …

LSU Doctoral Dissertations

A modified version of the Eating and Food Literacy Behaviors Questionnaire (EFLBQ) with a new construct called cooking enjoyment was developed and validated. The instrument was titled the Eating and Food Literacy Behavior Questionnaire with Cooking Enjoyment (EFLBQ-C). The EFLBQ-C was developed with data from 18- to 30-year-olds who attended a university in the United States collected by an online survey platform. The 515 students who completed the questionnaire answered using a 4-point Likert scale of Never=1,” “Seldom=2,” “Often=3,” and “Always=4.” The responses were divided into an EFLBQ-C cohort (Group 1: 258 participants) and an EFLBQ cohort (Group 2: 257 …

From Empowerment Movement To Hijacked Hashtag: A Thematic Analysis Of #Shoutyourabortion, Sidney R. Reynen

LSU Master's Theses

This study delves into the digital landscape of the contentious abortion debate, focusing on the use and hijacking of the Shout Your Abortion hashtag. Drawing parallels to previous research on digital feminism, hashtag activism, and hashtag hijacking, this study further expands such literature by revealing shifts in anti-abortion rhetoric and strategies post-Dobbs. I identified seven themes within the supportive discourse: abortion narratives, pro-choice and other feminist rhetoric, calls to action, feminist art and shareables, reproductive health information and resources, positive-to-neutral mentions of the movement, and engagements with anti-abortion users. Within the hijacked posts, I identified five themes: Shout …

Containerized Satsuma Mandarin Production Under Protective Screens As A Management Strategy, Anna Timmerman

LSU Master's Theses

Many of the world’s citrus growing regions are experiencing challenges related to citrus greening, also known as Huanglongbing (HLB) caused by the presumed bacterial agent Candidatus Liberibacter spp. HLB is vectored by the Asian citrus psyllid (Diaphorina citri) and through propagation of infected citrus material. HLB impacts tree health as well as fruit development, ripening, and quality of the resulting citrus fruit, often leading to an unmarketable product. Producers are growing citrus in high density orchards underneath protective screening material that excludes the Asian citrus psyllid, preventing new HLB infections. Four ultra-high containerized tree spacings of 2 feet …

Faculty Publications

There is a pressing need for more-holistic approaches to fisheries assessments along with growing demand to reduce the health impacts of sample collections. Metabolomic tools enable the use of sample matrices that can be collected with minimal impact on the organism (e.g., blood, urine, and mucus) and provide high-throughput, untargeted biochemical information without the requirement of a sequenced genome. These qualities make metabolomics ideal for monitoring a wide range of fish species, particularly those under protected status. In the current study, we surveyed the relative abundances of 120 endogenous metabolites in epidermal mucus across eight freshwater fish species belonging to …

A Descriptive Study Of Louisiana 4-H 8th Through 12th Graders' Perceptions Of Career And College Readiness, Carrie M. Lane

LSU Master's Theses

As youth leave primary education and enter college or a career path, preparing those youth to ensure success has fallen, in large part, upon formal and non-formal youth educators. Encouraging students to apply and complete college has been a focus of education professionals for many years. Historically, gauging college and career readiness (CCR), academic institutions have relied on academic performance in areas of English Language Arts and Mathematics (Mattern, et. al, 2014). The use of academic focused measures instead of student-based evaluation had its drawbacks. While core education is important, measuring soft skills needed for the workforce and college environment …

Effects Of A Major Hurricane On Dynamics, Structure, And Composition Of Mississippi River Delta Forests, Lance C. Umlang

LSU Doctoral Dissertations

Tropical cyclones recurrently influence coastal forests worldwide. Tree survival (resistance) and post-cyclone recruitment (resilience) can vary with cyclone intensity, producing differences in composition, arboreal structure, and dynamics among affected forests. Studies of tropical cyclone wind effects on coastal forests typically emphasize damage more than post-cyclone responses. We hypothesized that intense cyclones might produce large, stratum-dependent effects that prevent affected forests from returning to pre-storm conditions. We explored direct effects of major Hurricane Katrina and post-hurricane changes in oak-dominated bottomland and cypress/tupelo-dominated swamp forests within the inactive portion of the Mississippi River deltaic plain. Overall mortality was high (14-25%) but concentrated …

Yeast Crf1p: An Activator In Need Is An Activator Indeed, Sanjay Kumar

LSU Doctoral Dissertations

Ribosome biogenesis is an energetically costly process, and tight regulation is required for stoichiometric balance between components. This requires coordination of RNA polymerases I, II, and III. Lack of nutrients or the presence of stress leads to downregulation of ribosome biogenesis, a process for which mechanistic target of rapamycin complex I (mTORC1) is key. mTORC1 activity is communicated by means of specific transcription factors, and in yeast, which is a primary model system in which transcriptional coordination has been delineated, transcription factors involved in regulation of ribosomal protein genes include Fhl1p and its cofactors, Ifh1p and Crf1p. Ifh1p is an …

Becoming Avian: Amazonian Featherworks From The John P. O’Neill Collection, Madeline R. Blanchard

LSU Master's Theses

In 1998 ornithologist John P. O’Neill donated an ethnographic collection of 434 objects he was gifted from researcher Charles Fugler or purchased from persons in Pucallpa, Peru, during his time there studying Amazonian birds.

Exploring performance and pedagogy, the study considers examples from Medtner’s recordings of his Sonata Tragica, Op. …

Proud Of Your Boy: Toxic Masculinity, Boyhood, And The American Musical, Aaron J. Wood

LSU Doctoral Dissertations

This project traces the cultural historiography of the phrase "boys will be boys" and examines the pattern of white male excusal it embodies through a case-study based survey of onstage depictions of boyhood in musical theatre. I argue that the generational idea of manhood as aggressive, competitive, and violent is continually reasserted through our passive acceptance of white boy violence. This dissertation looks to the musicals Newsies, West Side Story, Heathers, and Dear Evan Hansen as case studies for exploring the cultural lineage of the phrase “boys will be boys.” Like the works of Aaron Thomas, Raymond …

Building Solidarity Between Minority Groups, Seonwoo Kim

LSU Doctoral Dissertations

Although a considerable number of scholars agree that an intergroup coalition among minorities will be more powerful in changing biased perceptions, regulations, and policies (e.g., Burson & Godfrey, 2020; Lane et al., 2019), cross-minority solidarity is challenging due to the inherent difficulties in establishing a shared goal and reaching a consensus on methods and tactics (Gawerc, 2021; Rogers, 2004) and competing policy stances and stereotypes (Hope, 2019; Nopper, 2006). Numerous instances of social movements that failed due to the failure of coalitions to form have been documented in the literature (e.g., Almeida, 2010; Ferree & Roth, 1998; Gelb & Shogan, …
