Influence Of Soldiers On Exploratory Foraging Behavior In The Formosan Subterranean Termite, Coptotermes Formosanus (Blattodea: Rhinotermitidae), Joseph Mccarthy, Arjun Khadka, Hasim Hakanoglu, Qian Sun

Faculty Publications

Termites are eusocial insects that live in organized colonies consisting of reproductives, workers, and soldiers. Soldiers are specialized for defense but are expensive to maintain, as they are incapable of husbandry and must be fed and groomed by workers. The soldiers of several species influence foraging behavior by acting as scouts that initiate foraging or by mediating worker behavioral plasticity during food exploration. These behaviors imply that soldiers may play a keystone role in termite colony function, apart from defense. Subterranean termite workers tunnel through soil in search of food while accompanied by varying proportions of soldiers, depending on the …

Temporal Features Of Concepts Are Grounded In Time Perception Neural Networks: An Eeg Study, Karim Johari, Vicky T. Lai, Nicholas Riccardi, Rutvik H. Desai

Faculty Publications

Experimental evidence suggests that modality-specific concept features such as action, motion, and sound partially rely on corresponding action/perception neural networks in the human brain. Little is known, however, about time-related features of concepts. We examined whether temporal features of concepts recruit networks that subserve time perception in the brain in an EEG study using event and object nouns. Results showed significantly larger ERPs for event duration vs object size judgments over right parietal electrodes, a region associated with temporal processing. Additionally, alpha/beta (10–15 Hz) neural oscillation showed a stronger desynchronization for event duration compared to object size in the right …

Opioid And Cannabis Co-Use: The Role Of Opioid Use To Cope With Negative Affect, Julia D. Buckner, Caroline R. Scherzer, Andrew H. Rogers, Michael J. Zvolensky

Faculty Publications

Introduction: The opioid epidemic is a significant public health concern, particularly among adults with chronic pain. There are high rates of cannabis co-use among these individuals and co-use is related to worse opioid-related outcomes. Yet, little work has examined mechanisms underlying this relationship. In line with affective processing models of substance use, it is possible that those who use multiple substances do so in a maladaptive attempt to cope with psychological distress. Method: We tested whether, among adults with chronic lower back pain (CLBP), the relation between co-use and more severe opioid-related problems would occur via the serial effects of …

The objective of this research was to analyze the effects of the SARS-CoV-2 virus on the sensory and cognitive perception of mild and severe COVID-19 diagnosed and recovered consumers versus healthy consumers. Three groups of 50 consumers each (healthy vs. mild and severe COVID-19 diagnosed with 30 days after recovery) were used for the evaluation of instant coffee stimuli in concentrations: 4.40, 2.93, 2.20, 1.76, and 1.47% weight (w)/volume (v) and determine their discriminating power, emotions, and memories. Sensory tests were performed remotely. Results indicated that healthy consumers perceived higher intensities in most of the sensory attributes (with the exception …

Total Utilization-Upcycling Of Mushroom Protein By-Product: Characterization And Assessment As An Alternative Batter Ingredient For Fried Shrimp, Diego Garcia, Seung Woon You, Ricardo S. Aleman, Joan M. King, Slavko Komarnytsky, Roberta Targino Hoskin, Marvin Moncada

Faculty Publications

Mushroom by-products are economical and eco-friendly raw materials with bioactive and functional characteristics that allow for potential uses as food ingredients. However, mushroom upcycling has yet to be fully exploited, despite the many opportunities that mushrooms may offer. The mushroom protein by-product (MPBP) resulting from mushroom protein production was characterized (chemical composition, physicochemical attributes, and functional properties) and incorporated into plant-based batter formulations to prepare four experimental groups with different ratios (w/w, %) of wheat flour (W) to MPBP (100 W, 75 W/25 MPBP, 25 W/75 MPBP, and 100 MPBP). Subsequently, the batter was used for frying batter-coated shrimp, which …

Non-Equilibrium Colloidal Phenomena In Magnetic Fields And Photoillumination: From Controlling Living Microbots To Understanding Microplastics, Ahmed Al Harraq

LSU Doctoral Dissertations

Colloids are a ubiquitous class of materials composed of microscopic particles suspended in a continuous phase which are found in everyday products and in nature. Colloids are also useful models for studying the spontaneous arrangement of matter from individual building blocks to mesophases. Standard treatment of colloid science is based on the assumption of equilibrium conditions, as defined in traditional thermodynamics. However, novel assembly mechanisms and motility are unlocked by pushing colloids away from equilibrium using external energy. In addition, many colloids in nature and in industrial applications exchange energy and mass with the surrounding environment thus behaving in a …

The Impacts Of Immune Challenges On Fish Behavior And Physiology, Teisha King

LSU Doctoral Dissertations

For species living in dominance hierarchies, social rank dictates access to resources and often contributes to reproductive success. To ensure survival, individuals constantly evaluate trade- offs between crucial biological systems, like the reproductive and immune systems, depending on their social rank and physiological state. Little is known about how social species balance interactions between immune system function, fluctuations in social status and reproductive fitness, and the performance of behaviors necessary for maintaining social status when sick, particularly in fishes, the largest and most diverse group of vertebrates. My dissertation research uses a whole animal approach to examine how physiological profiles …

Finding Forensic Evidence In The Operating System's Graphical User Interface, Edward X. Wilson Mr.

LSU Master's Theses

A branch of cyber security known as memory forensics focuses on extracting meaningful evidence from system memory. This analysis is often referred to as volatile memory analysis, and is generally performed on memory captures acquired from target systems. Inside of a memory capture is the complete state of a system under investigation, including the contents of currently running as well as previously executed applications. Analysis of this data can reveal a significant amount of activity that occurred on a system since the last reboot. For this research, the Windows operating system is targeted. In particular, the graphical user interface component …

Contagious Animality: Species, Disease, And Metaphor In Early Modern Literature And Culture, Jeremy Cornelius

LSU Doctoral Dissertations

In my dissertation, Contagious Animality: Species, Disease, and Metaphor in Early Modern Literature and Culture, I close read examples of Renaissance drama alongside their contemporary cultural texts to examine anxieties around social differences as constructed and mediated through what I call “contagious animality” in early modern English culture. Animal metaphors circulated anxieties around social differences on the early modern cultural stage in English drama where animality elicits uncertainties about identitarian constructions of difference. In this vein, I close read formal elements and their interactions with early modern culture to argue that animal metaphors transmit modes of speciating difference in …

Media Literacy In Public Education: A Mixed-Method Exploration, Jessica Wyers

LSU Doctoral Dissertations

You have to know where you are to know where you’re going. This is the approach I attempt to take to understand next steps in media literacy education and policy. Little research has been done to understand the current state of media literacy education, what is actually happening in the classrooms and education system, to better judge more intentional interventions in the future.

This dissertation explores the current issues in media literacy education in our public schools. I combine the strengths of a qualitative investigation of published public school media literacy curricula with survey data measuring the perceptions of students’ …

Characterization Of Antiviral Immunity, Host Virus Interactions, And Toxicity Of Agrochemical Residues In The Western Honey Bee, Christopher Fellows

LSU Doctoral Dissertations

Honey bee colonies have perished at an alarming rate for over 15 years. Among the multitude of threats to bee health, virus infections and agrochemical exposure appear to be major drivers of colony loss. As virus infection is among the most damaging influences on bee health, we first investigated a putative target for antiviral immunity, termed K_ATP channels. We previously demonstrated that pharmacologically activating K_ATP channels induces the production of reactive oxygen species and increases survival during infection with Israeli Acute Paralysis Virus. Here, we demonstrate that K_ATP modulation and ROS induction reduce virus replication and enhance …

Background: Taking fewer than the widely promoted "10 000 steps per day" has recently been associated with lower risk of all-cause mortality. The relationship of steps and cardiovascular disease (CVD) risk remains poorly described. A meta-analysis examining the dose-response relationship between steps per day and CVD can help inform clinical and public health guidelines. Methods: Eight prospective studies (20 152 adults [ie, ≥18 years of age]) were included with device-measured steps and participants followed for CVD events. Studies quantified steps per day and CVD events were defined as fatal and nonfatal coronary heart disease, stroke, and heart failure. Cox proportional …

Flood Risk Assessment For Residences At The Neighborhood Scale By Owner/Occupant Type And First-Floor Height, Ayat Al Assi, Rubayet Bin Mostafiz, Carol J. Friedland, Md Adilur Rahim, Robert V. Rohli

Faculty Publications

Evaluating flood risk is an essential component of understanding and increasing community resilience. A robust approach for quantifying flood risk in terms of average annual loss (AAL) in dollars across multiple homes is needed to provide valuable information for stakeholder decision-making. This research develops a computational framework to evaluate AAL at the neighborhood level by owner/occupant type (i.e., homeowner, landlord, and tenant) for increasing first-floor height (FFH). The AAL values were calculated here by numerically integrating loss-exceedance probability distributions to represent economic annual flood risk to the building, contents, and use. A simple case study for a census block in …

Understanding Meteorological Changes Following Severe Defoliation During A Strong Hurricane Landfall: Insights From Hurricane Michael (2018), Shannon A. Nelson, Paul W. Miller

Faculty Publications

Despite prompting persistent meteorological changes, severe defoliation following a tropical cyclone (TC) landfall has received relatively little attention and is largely overlooked within hurricane preparedness and recovery plan-ning. Changes to near-track vegetation can modify evapotranspiration for months after tropical cyclone passage, thereby altering boundary layer moisture and energy fluxes that drive the local water cycle. This study seeks to understand poten-tial spatial and temporal changes in defoliation-driven meteorological conditions using Hurricane Michael (2018) as a testbed. In this sensitivity study, two Weather Research and Forecasting (WRF) Model simulations, a normal-landscape and a post-TC scenario, are compared to determine how a …

Sudden Reduction Of Antarctic Sea Ice Despite Cooling After Nuclear War, Joshua Coupe, Cheryl Harrison, Alan Robock, Alice Duvivier, Elizabeth Maroon, Nicole S. Lovenduski, Scott Bachman, Laura Landrum, Charles Bardeen

Faculty Publications

A large-scale nuclear war could inject massive amounts of soot into the stratosphere, triggering rapid global climate change. In climate model simulations of nuclear war, global cooling contributes to an expansion of sea ice in the Northern Hemisphere. However, in the Southern Hemisphere (SH), an initial expansion of sea ice shifts suddenly to a 30% loss of sea ice volume over the course of a single melting season in the largest nuclear war simulation. In smaller nuclear war simulations an expansion in sea ice is instead observed which lasts for approximately 15 years. In contrast, in the largest nuclear war …

Global Sea Surface Cyclogeostrophic Currents Derived From Satellite Altimetry Data, Yuhan Cao, Changming Dong, Alexandre Stegner, Brandon J. Bethel, Chunyan Li, Jihai Dong, L. Haibin, Jingsong Yang

Faculty Publications

Sea surface currents (SSC) derived from the sea surface height anomalies (SSHA) as measured by multi-satellite altimeters are widely used for various applications including studies on ocean dynamics, marine ecology, and climate change. However, present SSC products estimated on the assumption of an idealized geostrophic balance is biased. To overcome this idealization, this study considers flow curvature in the estimation of sea surface velocities in the global ocean, with the computation scheme validated using numerical model results. It is demonstrated that the inclusion of curvature into SSC estimations significantly changes SSC dynamic features in terms of kinetic energy, enstrophy (the …

Floodsafehome: Evaluating Financial Benefits And Savings Of Freeboard For Improved Decision-Making In Flood Risk Mitigation, Carol J. Friedland, Yong Cheol Lee, Rubayet Bin Mostafiz, Jiyoung Lee, Shifat P. Mithila, Robert V. Rohli, Md Adilur Rahim, Ehab Gnan, Monica Teets Farris

Faculty Publications

Freeboard—elevation of a structure above the base flood elevation (BFE)—is a critical component in mitigating or avoiding flood losses. However, the unrevealed benefits and savings of freeboard installation have prevented communities from adopting this approach. To improve decision-making for residents, prospective residents, and other stakeholders in flood-vulnerable communities and enhance flood risk mitigation strategies, this study presents the methodology underlying a new webtool, FloodSafeHome, that estimates comprehensively the economic benefits and savings of freeboard installation for new construction of residential buildings. Specifically, the proposed evaluation framework has been designed to calculate monthly savings for individual buildings by assessing freeboard cost, …

Mey, Christine A. Karpinski, Shengping Yang, Joseph D. Madere, Tavis Piattoly, Ronnie Harper, John P. Kirwan

Division of Basic Science Faculty Publications

Background: Relative energy deficiency in sport (RED-S) as a consequence of athlete malnutrition remains a prominent issue. However, it remains underrecognized, in part due to the perceived outward health of athletes. The Eat2Win app was designed to combat RED-S and athlete malnutrition by providing education, behavior modification, and direct communication with expert sports dietitians to athletes and sport professionals (professionals who work with athletes, eg, sport coaches and athletic trainers). Objective: The purpose of this formative research was to gain critical insight on motivators and barriers to optimal nutritional intake from both the athletes’ and sport professionals’ perspectives. Additionally, since …

Challenges In The Combination Of Radiotherapy And Immunotherapy For Breast Cancer, Rui Zhang, Samantha D. Clark, Beibei Guo, Tianyi Zhang, Duane Jeansonne, Samithamby J. Jeyaseelan, Joseph Francis, Weishan Huang

Faculty Publications

Introduction: Immunotherapy (IT) is showing promise in the treatment of breast cancer, but IT alone only benefits a minority of patients. Radiotherapy (RT) is usually included in the standard of care for breast cancer patients and is traditionally considered as a local form of treatment. The emerging knowledge of RT-induced systemic immune response, and the observation that the rare abscopal effect of RT on distant cancer metastases can be augmented by IT, have increased the enthusiasm for combinatorial immunoradiotherapy (IRT) for breast cancer patients. However, IRT largely follows the traditional sole RT and IT protocols and does not consider patient …
