Promoter-Proximal Chromatin Domain Insulator Protein Beaf Mediates Local And Long-Range Communication With A Transcription Factor And Directly Activates A Housekeeping Promoter In Drosophila, Yuankai Dong, S. V. Satya Prakash Avva, Mukesh Maharjan, Janice Jacobi, Craig M. Hart

Faculty Publications

Copyright © 2020 by the Genetics Society of America BEAF (Boundary Element-Associated Factor) was originally identified as a Drosophila melanogaster chromatin domain insulator-binding protein, suggesting a role in gene regulation through chromatin organization and dynamics. Genome-wide mapping found that BEAF usually binds near transcription start sites, often of housekeeping genes, suggesting a role in promoter function. This would be a nontraditional role for an insulator-binding protein. To gain insight into molecular mechanisms of BEAF function, we identified interacting proteins using yeast two-hybrid assays. Here, we focus on the transcription factor Serendipity d (Sry-d). Interactions were confirmed in pull-down experiments using …

Sugarcane And Sugar Yields In Louisiana (1911–2018): Varietal Development And Mechanization, Andrew Schmitz, P. Lynn Kennedy, Fangyi Zhang

Faculty Publications

© 2020 The Authors. Crop Science © 2020 Crop Science Society of America Louisiana is the second largest producer of sugarcane (Saccharum officinarum L.) in the United States. New sugarcane cultivars better adapted for Louisiana have been in development since the inception of a three-way cooperative breeding program in the 1920s. Piecewise regression is used to determine the growth in both Louisiana sugarcane and sugar yields and how new sugarcane cultivars and mechanization have had a positive impact of yields. The analysis uses several breakpoints for periods between 1911 and 2018 to consider the impact of varietal development and mechanization. …

The Triple Oxygen Isotope Composition Of Precambrian Chert, Frasier L. Liljestrand, Andrew H. Knoll, Nicholas J. Tosca, Phoebe A. Cohen, Francis A. Macdonald, Yongbo Peng, David T. Johnston

Faculty Publications

© 2020 Elsevier B.V. The temperature and chemistry of early seawater have both been inferred from the isotopic composition of Precambrian chert (SiO2), a precipitated mineral formed on or within marine sediments. The δ18O of chert shows a robust quasi-linear increase through time - a signal that has been interpreted in a number of conflicting ways. For example, changing δ18O has been hypothesized to reflect the product of cooling surface ocean temperatures, a signature of evolving seawater δ18O composition, or the product of later stage diagenesis (where measured δ18O reflects the composition of diagenetic fluids). We suggest this uncertainty can …

Quasilinear Riccati-Type Equations With Oscillatory And Singular Data, Quoc Hung Nguyen, Nguyen Cong Phuc

Faculty Publications

We characterize the existence of solutions to the quasilinear Riccati-type equation [EQUATION PRESENTED] with a distributional or measure datum . Here divA(x) is a quasilinear elliptic operator modeled after the p-Laplacian (p > 1), and is a bounded domain whose boundary is sufficiently flat (in the sense of Reifenberg). For distributional data, we assume that p > 1 and q > p. For measure data, we assume that they are compactly supported in, p > 3n.2 2n-1 , and q is in the sub-linear range p -1 > q > 1.We also assume more regularity conditions on A and on δωω in this case.

Single nucleotide polymorphisms (SNPs) are highly abundant, amendable to high-throughput genotyping, and useful for a number of breeding and genetics applications in crops. SNP frequencies vary depending on the species and populations under study, and therefore target SNPs need to be carefully selected to be informative for each application. While multiple SNP genotyping systems are available for rice (Oryza sativa L. and its relatives), they vary in their informativeness, cost, marker density, speed, flexibility, and data quality. In this study, we report the development and performance of the Cornell-IR LD Rice Array (C7AIR), a second-generation SNP array containing 7,098 markers …

Virtual Touch: Embodied Experiences Of (Dis)Embodied Intimacy In Mediatized Performance, Naomi Petrea Bennett

LSU Doctoral Dissertations

In this dissertation, I explore a phenomenon I call virtual touch, in which embodied sensations of touch are felt through non-tactile senses. In the digital age, online interactivity has expanded the ways in which individuals experience connection, intimacy, and touch. Digital media, which have traditionally been thought of as disembodied, nevertheless have the ability to elicit intense feelings of touch. Through analysis of digital and virtual installation art, I examine the ways that non-tactile touch remains rooted in the embodied experience. The works I include in this study create a feeling of virtual touch through a co-functioning of the …

Purpose: Local tomography reconstruction is achievable with EPID images acquired during VMAT and was named as VMAT-CT. However, it did not gain popularity due to multiple limitations and technical challenges. The goal of this study was to extend VMAT-CT concept, generate complete 3D or 4D CT images and dose, track and adapt VMAT plan based on updated images and dose.

Methods: We considered collimator angle and removed blurred areas in EPID images for VMAT-CT reconstruction to reduce artifacts and improve image quality. VMAT-CT+ images were generated by fusing VMAT-CT and planning CT using rigid or deformable registration. For 4D SBRT …

On Characterizing Quantum Processes And Detectors, Kevin Valson Jacob

LSU Doctoral Dissertations

In 2009, physicists at the National Institute of Standards and Technology in Colorado, Boulder developed what could arguable be called the first rudimentary quantum computer [1]. The past decade has seen unprecedented improvements in quantum information science culminating in the demonstration of quantum supremacy --- that quantum computers can solve problems that are impractical to be solved on the best supercomputers [2]. This remarkable progress necessitates the development of techniques to characterize the quantum devices that are being developed. In my thesis, I will focus on such devices that manipulate and detect light.

In Chapter 1, I will introduce the …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

Why Do You Take That Route?, Alimire Nabijiang

LSU Master's Theses

We conducted this study to investigate causal factors which affects the route-choice behavior of drivers. Due to the insufficiency of measured variables and the lack of high-fidelity properties obtained by conventional data, we carried out Stated Choice Experiment (SCE) using Immersive Virtual Environments (IVE) tool to collect data. IVE tool can provide realistic virtual experiences to participants, and give advantage of flexible environment for exploring causal factors of drivers’ decision on route choice. Based on reviewing literatures, we believe that there is limited studies that has tried to comprehend the route choice behavior of drivers using causal inference. The study …

Night Of The Witch: Alternative Spirituality, Identity And Media, Andreana Tarleton

LSU Master's Theses

This thesis works to understand the relationships witches and conjurors have with the film and television depictions of them. Employing the method of film critique, I argue that the witch stands as a cultural symbol in the US of women and femmes with power, and that their stories serve as lessons to these populations about what it means to be an acceptable woman or femme, while simultaneously creating and perpetuating stereotypes of magic practitioners. Then, using the combination of hashtag ethnography, in-person and video interviewing and internet surveys, I argue that #witchblr and #witchesofcolor, as well as the space of …

The Voice Of Honor: Centering An Indigenous Ethic Of Protocol In U.S. Rhetorical Studies, Dakota Sandras

LSU Master's Theses

This project takes seriously the pressing rhetorical questions facing the field of communication studies which illuminate opportunity for radical disciplinary transformation and demand action beyond heightened racial and cultural awareness. In response, I seek to demonstrate that centering Indigenous epistemologies might inform and advance decolonial strategies for change. More specifically, I examine the theory and practice of First Nations customs of protocol and develop what I deem an ethic of protocol consisting of honor, humility, and action. After observing how these core tenets function synergistically in the protocol of elders, rites of passage, and entering another’s land, I argue that …

Physical And Biological Factors Controlling The Fate Of Nitrate In A Louisiana Coastal Deltaic Floodplain, Alexandra Christensen

LSU Doctoral Dissertations

The Mississippi River Delta is threatened by a growing pressure to support large human populations in the United States both with food production, navigation systems, and urban development in the Mississippi River Basin. Nitrate-nitrogen load in the Mississippi River, up to 100 Tg N yr^-1 from agricultural and urban runoff, leads to phytoplankton blooms and hypoxia across the Louisiana continental shelf, creating dead zones of low dissolved oxygen threatening a significant commercial fishery. Along the coast and river corridors, floodplain ecosystems have the capacity to retain and remove nitrate. This dissertation explores the role of productive, actively growing coastal …
