Red Harvester Ant, Pogonomyrmex Barbatus, Nests Impact Soil Compaction But Not Temperature In Peri-Urban Habitats Of The Lower Rio Grande Valley, Geovanni Hernandez, Hannah J. Penn, Richard Cano, Lilly Victoria Elliott-Vidaurri, Robin A. Choudhury

School of Earth, Environmental, & Marine Sciences Faculty Publications

Ants are vital ecosystem engineers that can influence soil properties, subsequent soil processes, and associated biota via underground nest construction. Harvester ants consume seeds and are often found in arid areas. They frequently alter the soil chemistry and bulk density of the soils in and around their nest sites. Many species of harvester ants also intentionally remove vegetation around their nest openings, which creates cones or discs of bare soil that may further alter soil temperatures. However, much of the work to study the impacts of harvester ants on soil properties has occurred in shrubland and grassland settings rather than …

Learning-Based Artifacts Removal Priors For Computational Imaging, Jiaming Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

This dissertation addresses the integration of physical models with learning-based artifact removal priors for computational imaging. The motivation for our work stems from the growing interest in combining imaging models, which ensure data consistency with observed measurements, with deep learning, which provides advanced data-driven prior modeling. Following this approach, we adopt classic statistical inference as the foundational framework and integrate deep artifact removal models as image priors. This allows our framework to simultaneously leverage both physical models and learning-based priors. Furthermore, the increasing size of images and measurements in modern computational imaging systems imposes significant computational and memory burdens. Another …

Chemistry Faculty Publications and Presentations

Waterpipe tobacco (WPT) smoking is a public health concern, particularly among youth and young adults. The global spread of WPT use has surged since the introduction of pre-packaged flavored and sweetened WPT, which is widely marketed as a safer tobacco alternative. Besides flavorants and sugars, WPT additives include humectants, which enhance the moisture and sweetness of WPT, act as solvents for flavors, and impart smoothness to the smoke, thus increasing appeal to users. In the United States (U.S.), unlike cigarette tobacco flavoring (with the exception of menthol), there is no FDA product standard or policy in place prohibiting sales of …

Diving Deeper Into Supercuspidal Representations, Prerna Agarwal

LSU Doctoral Dissertations

In 2013, Reeder and Yu introduced certain low positive depth supercuspidal representations of $p$-adic groups called \textit{epipelagic} representations. These representations generalize the simple supercuspidal representations of Gross and Reeder, which have the lowest possible depth. Epipelagic representations also arise in recent work on the Langlands correspondence; for example, simple supercuspidals appear in the automorphic data corresponding to the Kloosterman $l$-adic sheaf. In this thesis, we take a first step towards the construction of ``\textit{mesopelagic} representation (of Iwahori type)'' which are the higher depth analogues of simple supercuspidal representations. We see that these constructions can be done in a similar way …

An Analysis Of The Development Of Cognitive Control In Young Children Within An Auditory And Visual Modality., Lauren A. Schiro

LSU Master's Theses

The Dual Mechanisms of Cognitive Control Framework (DMC) posits that cognitive control is directed through two different modes: proactive and reactive control. Proactive control involves the maintenance and manipulation of information in preparation of a response while reactive control would involve little to no preparation until after a response prompt. The AX-Continuous Performance Task (AX-CPT) is a cognitive control task that is often utilized in studies looking at proactive and reactive control as it measures context processing and goal maintenance. The aims of this study were to validate the auditory version of the AX-CPT and to then apply this task …

Identifying Driving Factors Of Inundation Susceptibility In Thailand With The Frequency Ratio Method, Zachary Zoet, Jim Wilson

The Geographical Bulletin

Inundation models tend to cover geographically small areas at large-scales. Inconsistencies in research design arising from data classification methods and consensus about unit of analysis, and agreement on the choice of a consistent modeling method can lead to confusion in the selection of appropriate models for different inundation scenarios. To address these concerns, this study aims to expand on the Frequency Ratio Method, using 13 quantitative and qualitative variables, as a generalizable method that can be applied consistently across larger administrative areas such as the province. The ultimate product of this is a Flood Susceptibility Index (FSI), which can be …

Dr. Geographer Or: How I Learned To Think Spatially And Love Maps, Randy Bertolas

The Geographical Bulletin

Most people measure their lives by time. How much, how long, how soon it will be over. I always think of life in terms of space and place. How to get to some place, how long a distance to that place, what it will be like at that place when I disembark. There are many reasons for approaching and entering the field of geography. Few of us can pinpoint the moment our love for geography began. I can. It was the day someone gave me a map.
