As focus for exploration of Mars transitions from current robotic explorers to development of crewed missions, it remains important to protect the integrity of scientific investigations at Mars, as well as protect the Earth's biosphere from any potential harmful effects from returned martian material. This is the discipline of planetary protection, and the Committee on Space Research (COSPAR) maintains the consensus international policy and guidelines on how this is implemented. Based on National Aeronautics and Space Administration (NASA) and European Space Agency (ESA) studies that began in 2001, COSPAR adopted principles and guidelines for human missions to Mars in 2008. …

Optimal Querying For Communication-Efficient Admm Using Gaussian Process Regression, Aldo Duarte, Truong X. Nghiem, Shuangqing Wei

Faculty Publications

In distributed optimization schemes consisting of a group of agents connected to a central coordinator, the optimization algorithm often involves the agents solving private local sub-problems and exchanging data frequently with the coordinator to solve the global distributed problem. In those cases, the query-response mechanism usually causes excessive communication costs to the system, necessitating communication reduction in scenarios where communication is costly. Integrating Gaussian processes (GP) as a learning component to the Alternating Direction Method of Multipliers (ADMM) has proven effective in learning each agent's local proximal operator to reduce the required communication exchange. A key element for integrating GP …

New Features Of Laboratory-Generated Epfrs From 1,2-Dichlorobenzene (Dcb) And 2-Monochlorophenol (Mcp), Lavrent Khachatryan, Marwan Y. Rezk, Divine Nde, Farhana Hasan, Slawomir Lomnicki, Dorin Boldor, Robert Cook, Phillip Sprunger, Randall Hall, Stephania Cormier

Faculty Publications

The present research is primarily focused on investigating the characteristics of environmentally persistent free radicals (EPFRs) generated from commonly recognized aromatic precursors, namely, 1,2-dichlorobenzene (DCB) and 2-monochlorophenol (MCP), within controlled laboratory conditions at a temperature of 230 °C, termed as DCB230 and MCP230 EPFRs, respectively. An intriguing observation has emerged during the creation of EPFRs from MCP and DCB utilizing a catalyst 5% CuO/SiO2, which was prepared through various methods. A previously proposed mechanism, advanced by Dellinger and colleagues (a conventional model), postulated a positive correlation between the degree of hydroxylation on the catalyst’s surface (higher hydroxylated, HH and less …

Producing Digital Reflections Of Reality Through Intercultural Filmmaking And Multisensory Engagement, Trai Thomas

LSU Doctoral Dissertations

This thesis analyzes the author’s production of three intercultural, multisensory films situated in New Orleans, encompassing elements both narrative and documentary genres. Intercultural cinema exists in a setting where people of different cultural backgrounds live together in power-inflicted spaces of diaspora, colonialism, and cultural apartheid and the development of the story is centered around exoticism, fetishization, and fascination with the other (Marks 2007, 1). Multisensory media primarily engages through visual perception and auditory input, which create cultural knowledge stored as long-term memory files in the brain (Marks 2007).

Molina, Leanne M. Redman, Corby K. Martin, Susan B. Racette, Kim M. Huffman, Manjushri Bhapkar, Sundeep Khosla, Sai Krupa Das, Roger A. Fielding, Elizabeth J. Atkinson, Nathan K. Lebrasseur

Clinical Research Faculty Publications

Calorie restriction (CR) with adequate nutrient intake is a potential geroprotective intervention. To advance this concept in humans, we tested the hypothesis that moderate CR in healthy young-to-middle-aged individuals would reduce circulating biomarkers of cellular senescence, a fundamental mechanism of aging and aging-related conditions. Using plasma specimens from the Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE™) phase 2 study, we found that CR significantly reduced the concentrations of several senescence biomarkers at 12 and 24 months compared to an ad libitum diet. Using machine learning, changes in biomarker concentrations emerged as important predictors of the change …

Effector-Triggered Susceptibility By The Rice Blast Fungus Magnaporthe Oryzae, Ely Oliveira-Garcia, Xia Yan, Miriam Oses-Ruiz, Samuel De Paula, Nicholas J. Talbot

Faculty Publications

Rice blast, the most destructive disease of cultivated rice world-wide, is caused by the filamentous fungus Magnaporthe oryzae. To cause disease in plants, M. oryzae secretes a diverse range of effector proteins to suppress plant defense responses, modulate cellular processes, and support pathogen growth. Some effectors can be secreted by appressoria even before host penetration, while others accumulate in the apoplast, or enter living plant cells where they target specific plant subcellular compartments. During plant infection, the blast fungus induces the formation of a specialized plant structure known as the biotrophic interfacial complex (BIC), which appears to be crucial for …

The Impact Of Information Presentation On Consumer Perceptions Of Cricket-Containing Chocolate Chip Cookies, Yupeng Gao, Pitchayapat Chonpracha, Bin Li, Ryan Ardoin, Witoon Prinyawiwatkul

Faculty Publications

As a source of protein and other nutrients for a growing population, edible insect production offers environmental and sustainability advantages over traditional meat production. Although around 2 billion people consume insects worldwide, Western consumers are still reluctant to practice entomophagy, hindered largely by neophobia and negative emotions. In addition to sensory quality and safety, an informational component may be crucial to consumers’ decision making involving insect consumption. In this study, three different information types, namely text, image, and a tangible product, were used to convey information about chocolate chip cookies (CCCs) containing cricket flour. The nature of the information was …

Understanding Implications Of Detection Heterogeneity In Wildlife Abundance Estimation, Jeffrey L. Laake, Bret A. Collier

Faculty Publications

Negative bias in mark-recapture abundance estimators due to heterogeneity in detection (capture) probability is a well-known problem, but we believe most biologists do not understand why heterogeneity causes bias and how bias can be reduced. We demonstrate how heterogeneity creates dependence and bias in mark-recapture approaches to abundance estimation. In comparison, heterogeneity, and hence estimator bias, is not as problematic for distance sampling and mark-resight methods because both techniques estimate detection probabilities based on a known quantity. We show how the introduction of a known number of individuals planted into a study population prior to a mark-recapture survey can reduce …

Decay Of Multi-Point Correlation Functions In Zd, Rui Han, Fan Yang

Faculty Publications

We prove multi-point correlation bounds in Z^d for arbitrary d≥1 with symmetrized distances, answering open questions proposed by Sims–Warzel (Commun Math Phys 347(3):903–931, 2016) and Aza–Bru–Siqueira Pedra (Commun Math Phys 360(2):715–726, 2018). As applications, we prove multi-point correlation bounds for the Ising model on Z^d, and multi-point dynamical localization in expectation for uniformly localized disordered systems, which provides the first examples of this conjectured phenomenon by Bravyi–König (Commun Math Phys 316(3):641–692, 2012).

Tremendous progress has been made in variety development and host plant resistance to mitigate the impact of Fusarium head blight (FHB) since the disease manifested in the southeastern United States in the early 2000s. Much of this improvement was made possible through the establishment of and recurring support from the US Wheat & Barley Scab Initiative (USWBSI). Since its inception in 1997, the USWBSI has enabled land-grant institutions to make advances in reducing the annual threat of devastating FHB epidemics. A coordinated field phenotyping effort for annual germplasm screening has become a staple tool for selection in public and private …

Hamiltonian Formulation And Symplectic Split-Operator Schemes For Time-Dependent Density-Functional-Theory Equations Of Electron Dynamics In Molecules, François Mauger, Cristel Chandre, Mette B. Gaarde, Kenneth Lopata, Kenneth J. Schafer

Faculty Publications

We revisit Kohn–Sham time-dependent density-functional theory (TDDFT) equations and show that they derive from a canonical Hamiltonian formalism. We use this geometric description of the TDDFT dynamics to define families of symplectic split-operator schemes that accurately and efficiently simulate the time propagation for certain classes of DFT functionals. We illustrate these with numerical simulations of the far-from-equilibrium electronic dynamics of a one-dimensional carbon chain. In these examples, we find that an optimized 4th order scheme provides a good compromise between the numerical complexity of each time step and the accuracy of the scheme. We also discuss how the Hamiltonian structure …

Faculty Publications

Sediment cores were collected from a mudflow lobe (80 m water depth) offshore of the Mississippi River’s Southwest Pass in 2017 to better understand the sedimentology near the lobe entraining the SS Virginia shipwreck (sunk by a German U-boat in 1942) and surrounding Mississippi River delta front. Core analyses included ²¹⁰Pb/¹³⁷Cs geochronology, granulometry, and X-radiography. Sediment accumulation rates (SAR) calculated from excess ²¹⁰Pb activity in multicores are 0.22–0.29 cm/y at seabed depths less than 20 cm and 0.29–0.51 cm/y at depths greater than 20 cm. Accumulation rates for ¹³⁷Cs have been ~0.15 to ~0.37 cm/y …

Energy And Spectrum Efficient Federated Learning Via High-Precision Over-The-Air Computation, Liang Li, Chenpei Huang, Dian Shi, Hao Wang, Xiangwei Zhou, Minglei Shu, Miao Pan

Faculty Publications

Federated learning (FL) enables mobile devices to collaboratively learn a shared prediction model while keeping data locally. However, there are two major research challenges to practically deploy FL over mobile devices: (i) frequent wireless updates of huge size gradients v.s. limited spectrum resources, and (ii) energy-hungry FL communication and local computing during training v.s. battery-constrained mobile devices. To address those challenges, in this paper, we propose a novel multi-bit over-the-air computation (M-AirComp) approach for spectrum-efficient aggregation of local model updates in FL and further present an energy-efficient FL design for mobile devices. Specifically, a high-precision digital modulation scheme is designed …

Conflict And Race In Literature & Law. The Case Of Americanah, Emanuela Ignatoiu Sora

Comparative Woman

In Americanah, the 2013 novel by Chimamanda Ngozi Adichie, there is a scene when one of the characters, Laura, speaks of her Ugandan classmate who did not get along with an African-American colleague. Laura is surprised as, for her, all persons of color are similar, with no understanding for their differences in background, personal stories and experiences. The novel depicts and critiques this very categorization of race, which flattens differences, conflating groups and individuals who might share very little, if anything. For a long time, law (with its stipulations, precedents and rulings) has operated in a similar manner, disengaging …

Parental Environnement Influences Offspring Gene Expression In The Olympia Oyster, Ostrea Lurida., Mark S. Yeats

LSU Master's Theses

The Olympia Oyster is the only native oyster species on the Pacific coast of North America. Seasonality in water temperatures across this threatened species’ broad and fragmented range has been linked to its development, reproductive timing, reproductive activity, growth, and survival rates. Recent evidence suggests parental environments can have carry-over effects on larval growth and respiration rates in response to temperature. In this study, we utilized transcriptomic methods to identify the underlying mechanisms of this cross-generation plasticity. Sequence libraries of adult ctenidia tissue and pooled larval replicates were extracted and spawned from hatchery raised oysters of the same parentage immediately …

In Search Of The Armorial Aesthetic: The Counter-Reform Of Ariano Suassuna And The Compositional Techniques In Clovis Pereira’S Suite Macambira, Wagner De Oliveira Duarte

LSU Doctoral Dissertations

Throughout the first half of the twentieth century, in the wake of the Week of Modern Art in São Paulo in 1922, Brazil grappled with defining its national identity, distinct from European influences. While eminent figures such as Villa-Lobos, Camargo Guarnieri, and Francisco Mignone provided foundational narratives in this quest, the Armorial movement emerged as a unique and emblematic response to these nationalistic aspirations.

Originating from the creative vision of Ariano Suassuna, the Armorial movement, though often perceived as a regional initiative, epitomized a broader endeavor to represent Brazil's diverse cultural tapestry. Central to understanding this movement is the work …
