Background: Increasing research suggests that gait abnormalities can be a risk factor for Alzheimer’s Disease (AD). Notably, there is growing evidence highlighting this risk factor in individuals with amnestic Mild Cognitive Impairment (aMCI), however further studies are needed. The aim of this study is to analyze cognitive tests results and brain-related measures over time in aMCI and examine how the presence of gait abnormalities (neurological or orthopedic) or normal gait affects these trends. Additionally, we sought to assess the significance of gait and gait-related measures as prognostic indicators for the progression from aMCI to AD dementia, comparing those who converted …

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this …

Atmospheric effects, such as turbulence and background thermal noise, inhibit the propagation of light used in ON-OFF keying (OOK) free-space optical (FSO) communication. Here we present and experimentally validate a convolutional neural network (CNN) to reduce the bit error rate of FSO communication in post-processing that is significantly simpler and cheaper than existing solutions based on advanced optics. Our approach consists of two neural networks, the first determining the presence of bit sequences in thermal noise and turbulence and the second demodulating the bit sequences. All data used for training and testing our network is obtained experimentally by generating OOK …

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 …

Background: Preschool children are not meeting recommended levels of physical activity (PA) nor are they proficient in fundamental motor skills (FMS), which are the foundation for PA. As such, interventions are needed to increase PA and FMS in young children. This trial examined the effects of an environmental (“painted playgrounds”) and capacity-building (written toolkit) intervention on child FMS, PA, and sedentary behavior at early childhood education (ECE) centers and examined feasibility. Methods: In a randomized controlled trial, four ECE centers were randomly assigned to an intervention group or wait-list control. For intervention centers, stencils were spray painted adjacent to playgrounds …

Background: Healthy eating and active living policy, systems, and environmental (PSE) changes are implemented across the United States through Cooperative Extension. However, translating multisector PSE changes to practice in community settings is challenging and there is a lack of knowledge about barriers and facilitators to PSE changes among state Extension systems using standardized frameworks. Therefore, a research-to-practice partnership effort aimed to identify Louisiana Cooperative Extension Service Family and Consumer Science (LFCS) practitioners’ barriers and facilitators to implementing PSE changes in rural Louisiana communities. Methods: A qualitative approach using the 2022 Consolidated Framework for Implementation Research (2022 CFIR) was used. Focus …

Emerging research suggests that body dissatisfaction (BD) is prevalent among midlife and older women (i.e., upwards of 70%). Cross-sectionally, BD is associated with myriad poor health and wellness outcomes (e.g., depression, disordered eating, bad nutrition) in midlife/older women. However, relatively few studies have examined the longitudinal relations between BD and health outcomes in this population. This preliminary study investigated the longitudinal associations of BD with wellbeing and health-related quality of life (QOL) among midlife/older adult women over one year. Participants (n = 86, women aged 40–72 years, M = 51.49, SD = 7.34, 86% white) completed self-report measures of BD, …

Background: Alterations in DNA methylation (DNAm) have been reported to be a mechanism by which bariatric surgeries resulted in considerable metabolic improvements. Previous studies have mostly focused on change in DNAm following weight-loss interventions, yet whether DNAm prior to intervention can explain the variability in glycemic outcomes has not been investigated. Here, we aim to examine whether baseline DNAm is differentially associated with glycemic outcomes induced by different types of weight-loss interventions. Methods: Participants were 75 adults with severe obesity who underwent non-surgical intensive medical intervention (IMI), adjustable gastric band (BAND) or Roux-en-Y gastric bypass (RYGB) (n = 25 each). …

A detailed uplift history of the Tibetan Plateau is essential for disentangling the proposed geodynamical models and assessing its impacts on climate and biodiversity. However, when and how the plateau formed remains highly controversial. Here, we present unusual geochemical indicators of marine signatures in the Cenozoic terrestrial strata of the Qaidam Basin, northern Tibetan Plateau, with strong implications for the basin altitude. Our investigations across the basin reveal typical marine alkenones and anomalously high carbonate carbon isotopic values during the mid-Miocene, but not at earlier stages, which are accompanied by a divergent trend in the paired carbonate oxygen and leaf …

Objective analytical identification methods are still a minority in the praxis of paleobiological sciences. Subjective interpretation of fossils and their modifications remains a nonreplicable expert endeavor. Identification of African bovids is a crucial element in the reconstruction of paleo-landscapes, ungulate paleoecology, and, eventually, hominin adaptation and ecosystemic reconstruction. Recent analytical efforts drawing on Fourier functional analysis and discrimination methods applied to occlusal surfaces of teeth have provided a highly accurate framework to correctly classify African bovid tribes and taxa. Artificial intelligence tools, like computer vision, have also shown their potential to be objectively more accurate in the identification of taphonomic …

Multiscale Analysis Of Spatial Accessibility To Acute Hospitals In Carinthia, Austria, Changzhen Wang, Michael Leitner, Gernot Paulus
Faculty Publications
Health care accessibility studies are well established in the US but lacking in Austria, even though both experience high costs and have hospital care as the largest contributor to health care spending. This study aims to examine multiscale spatial accessibility to acute hospitals in Carinthia, Austria. Using the most recent data at census block and 250 meter grid levels, we refine proximity and generalized two-step floating catchment area (G2SFCA) methods while accounting for the modifiable areal unit problem (MAUP) and edge effects. For census blocks and 250 meter grids, the mean travel times to the nearest acute hospitals are 16 …

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 …

The lifespan extension induced by 40% caloric restriction (CR) in rodents is accompanied by postponement of disease, preservation of function, and increased stress resistance. Whether CR elicits the same physiological and molecular responses in humans remains mostly unexplored. In the CALERIE study, 12% CR for 2 years in healthy humans induced minor losses of muscle mass (leg lean mass) without changes of muscle strength, but mechanisms for muscle quality preservation remained unclear. We performed high-depth RNA-Seq (387–618 million paired reads) on human vastus lateralis muscle biopsies collected from the CALERIE participants at baseline, 12- and 24-month follow-up from the 90 …

The principal nature-based solution for offsetting relative sea-level rise in the Ganges-Brahmaputra delta is the unabated delivery, dispersal, and deposition of the rivers’ ~1 billion-tonne annual sediment load. Recent hydrological transport modeling suggests that strengthening monsoon precipitation in the 21st century could increase this sediment delivery 34-60%; yet other studies demonstrate that sediment could decline 15-80% if planned dams and river diversions are fully implemented. We validate these modeled ranges by developing a comprehensive field-based sediment budget that quantifies the supply of Ganges-Brahmaputra river sediment under varying Holocene climate conditions. Our data reveal natural responses in sediment supply comparable to …

Effectively onboarding newcomers is essential for the success of open source projects. These projects often provide onboarding guidelines in their 'CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the …

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 …

An Intersection Of Science & Art: Vitrification Approaches And Open-Fabricated Tools For The Biomedical Model Sea Hare, Aplysia Californica, Allyssa M. Oune
LSU Master's Theses
The California sea hare (Aplysia californica) is an important biomedical model for molecular neurobiology, electrophysiology, learning, and memory due to their well-mapped and large neurons and well-characterized learning capabilities. The National Resource for Aplysia (NRA, University of Miami) maintains large stocks of live animals and relies on regular shipments of wild-caught individuals to maintain genetic diversity. This is labor and cost-intensive, and environmental changes could alter the availability of wild animals increasing the need to preserve this genetic resource. One solution is vitrification, ultra-fast cooling which produces an amorphous glass that minimizes damage to cells. Aplysia californica presents …

Surrogate-Assisted Simulation-Optimization Framework For Groundwater Management In A Multi-Aquifer System, Melika Mani
Surrogate-Assisted Simulation-Optimization Framework For Groundwater Management In A Multi-Aquifer System, Melika Mani
LSU Master's Theses
Uncontrolled groundwater exploitation can lead to aquifer depletion, land subsidence, and saltwater intrusion. Effective groundwater management is challenging due to the intricate nature of subsurface hydrogeology and spatiotemporally variable pumping, especially in a multi-aquifer system. To ensure sustainable withdrawal, multi-objective optimization is an effective tool for balancing management goals and drawdown effects. However, running simulation-optimization using detailed groundwater models is computationally expensive, pushing decision-makers to decide based on limited scenarios. In this study, a hydrogeological framework was constructed for the Capital Area, Louisiana, allowing for individual assessment of each unit to better understand each aquifer's condition. Moreover, a surrogate-assisted simulation-optimization …

Investigations Of Emerging Zoonotic And Vector-Borne Viruses At The Juncture Of Environmental, Human, And Animal Health, Erik A. Turner
LSU Doctoral Dissertations
Reemerging and emerging zoonotic viruses are some of the most important public and One Health threats facing the world. Understanding the transmission dynamics of these viruses is vital to reducing the disease burden, and one of the key aspects to these transmission systems is the environmental vertex of the One Health triangle. SARS-CoV-2 has only recently emerged as a global public health threat, and within 4 years, over 700 million cases have been reported. As a novel pathogen, many aspects of transmission, including environmental fomite transmission and disinfection, were initially a glaring gap in knowledge. Additionally, while chikungunya virus (CHIKV) …

Investing In Farmland And Farmland Derivatives, Damilola Stephen Adebayo
Investing In Farmland And Farmland Derivatives, Damilola Stephen Adebayo
LSU Master's Theses
Investing in farmland has evolved from the traditional ownership of farmland for farming to alternatives such as direct farmland purchases for rental income, farmland real estate investment trusts (Farmland REITs), investing in farmland stocks, mutual funds, ETFs, and crowdfunding platforms. This study analyzes the dynamic relationship between physical farmland values, farmland derivative prices, and the S&P 500 using annual data from 1970 to 2021. Cointegration methods are used to analyze dynamics and the capital asset pricing model (CAPM) and Sharpe ratios to measure risk-return properties of farmland assets. It is found that real farmland values, derivatives prices, and the S&P …

Induction Heating Driven Heterogeneous Catalysis: Magnetically Induced Nanoparticle Catalysts, Cameron Lee Roman
LSU Doctoral Dissertations
Heterogeneous catalysis has been and continues to be highly studied due to being one of the cornerstones of the chemical industry. With an increasing demand for chemicals and rising costs, there is a growing need to adapt to changing feed stocks and increase production efficiency. Polymers, oxygenates, and other chemical intermediates are predicted to experience continued growth, corresponding to an increased need for olefines. Due to the abundance of shale gas, researchers and producers are interested in meeting this demand via the dehydrogenation of light alkanes.
While dehydrogenation catalysts are a valuable tool in olefin production, selectivity and deactivation remain …

Air pollution is consistently linked with elevations in cardiovascular disease (CVD) and its mortality. Particulate matter (PM) is a pivotal factor in air pollution-associated CVD. PM containing environmentally persistent free radicals (EPFR) forms from the incomplete combustion of organic wastes. These products adhere to particulate matter carrying redox-active transition metals on its surface. To enable systematic research of the health impacts of EPFR, our colleagues developed a combustion method to produce EPFR-containing PM that closely resemble urban PM and validated their use for typical laboratory settings. We exposed mice to laboratory generated EPFR through whole-body inhalation and investigated their dose-dependent …
The Structures And Functions Of Offices Of Academic Affairs: A Case Study, Ryan Thomas Landry
The Structures And Functions Of Offices Of Academic Affairs: A Case Study, Ryan Thomas Landry
LSU Doctoral Dissertations
This study sought to describe how offices of academic affairs (administrative offices supporting provosts) at public, research-intensive universities in the United States are structured and what kind of work these offices do. There is a dearth of scholarly literature on the topic, indicative of an overall lack of knowledge about these organizations. From a practical standpoint, I intended for this study to contribute to the body of knowledge of higher education administration with hopes that it provides helpful insights to administrators as they consider organizational design. Using the theoretical framework of modern organization theory, I employed an embedded case study …
Translation Speed Influence On Tropical Cyclone Storm Tide And Surge Generation Along The Gulf Of Mexico Coast, Samantha L. Camarda
Translation Speed Influence On Tropical Cyclone Storm Tide And Surge Generation Along The Gulf Of Mexico Coast, Samantha L. Camarda
LSU Master's Theses
This research examines tropical cyclone translation speed as a factor in storm tide and surge height upon landfall on the United States Gulf Coast. Understanding the effect of translation speed on peak storm tide/surge height is needed to better prepare for and predict future damage from tropical cyclone events. Tropical cyclone data are taken from hourly interpolated best-track HURDAT2 data from 1970–2021. This study uses the HURDAT2 hourly interpolated observation data points (24-hours) pre-landfall to landfall. Translation speed is calculated based on the distance traversed between hourly points. Peak storm tide and storm surge data are taken from SURGEDAT from …
