Water Circulation Beneath A Hovering Suas For Water Quality Monitoring Applications, Erin E. Hackett, Boone Fleenor, Jensine C. Coggin, Duvall Dickerson-Evans, Nikolaos Vitzilaios, Whitney E. Schuler, Paige K. Williams, Michael L. Myrick

Faculty Publications

Water quality has traditionally been measured via in situ sensors and satellites. The latter has limited applicability for smaller inland water bodies, while the former requires significant logistics, labor, and expense for routine sampling, and reactive/spurious sampling is often not feasible as a result (e.g., sampling pre-/post-storm). Consequently, small uncrewed aircraft system-based (sUAS-based) sampling has emerged as a potential solution to bridge these sampling gaps and challenges. But sampling from an sUAS is complicated by the need to pump water from depth, rather than suspending a sensor from the sUAS, due to concern over sampling sUAS-impacted waters. Here, we measure …

Optimizing Endothelial Cell Specific Polymersome-Based Atheroprotective Therapies, Ally C. Brawner

All Theses

Atherosclerotic cardiovascular disease is the number one cause of death in the United States and the world. Every year, billions of dollars are spent in the US alone for direct treatments of this disease, especially on prescription medicines like statins. However, these medications have been unable to curtail global mortality rates, partially because they do not target the entirety of atherosclerotic pathophysiology. A key area of this pathophysiology is that atheroprone arteries typically include pro-inflammatory endothelial cells that exhibit decreased levels of apoAI-mediated cholesterol efflux and an increased release of adhesion molecules, such as VCAM-1. The objective of my project …

Effects Of Exercise Timing On Circadian Rhythm And Functional Outcomes In Cancer Patients Undergoing Treatment, Buck Williams Covington Ii

Dissertations

Poor sleep quality and circadian rhythm disruption are commonly reported among cancer survivors and may contribute to worsened health outcomes, including increased fatigue, psychological distress, and reduced quality of life. While some recent studies suggest that exercise can improve sleep and circadian regulation in cancer survivors, limited research exists on how the timing of this exercise affects these outcomes in cancer survivors. The purpose of this study was to examine the effects of a 12-week supervised exercise intervention, performed either in the morning (AX) or evening (PX), on functional capacity, subjective and objective sleep quality, and peripheral markers of circadian …

Assessing Male Asian Corn Borer, Ostrinia Furnacalis (Guenée) (Lepidoptera: Crambidae), Mating Frequency Via Spermatophore Quantification, Gelyn D. Sapin, Marcela M. Navasero

The Philippine Agricultural Scientist

The Asian corn borer (ACB), Ostrinia furnacalis (Guenée), has caused significant yield losses to corn due to its destructive feeding. Bt corn currently controls ACB, but it still poses a threat to Philippine traditional varieties. Random mating of ACB is essential to the insect resistance management (IRM) of Bt corn, and studying the mating behavior, specifically the mating frequency of ACB, is a critical part of understanding the IRM in the Philippines. Currently, there is no available information on the mating frequency of ACB. Here, the male and female ACB were allowed to mate at a ratio of 1 male …

Oviposition Preference And Behavior Of The Asian Corn Borer, Ostrinia Furnacalis (Guenée) (Lepidoptera: Crambidae), On Corn And Non-Corn Plants Under Semi-Field And Mini-Screen Cage Conditions, Merdelyn T. Caasi-Lit, Jessica B. Baroga-Barbecho, John David C. Cortez, Edwin A. Benigno

The Philippine Agricultural Scientist

Oviposition site selection in Ostrinia furnacalis is a hierarchical, multi-stage process influenced by plant phenology and spatial context. Oviposition preferences under mini-screen cage (Sampaloc) and semi-field (BL2) conditions were evaluated to determine the effects of field size, corn developmental stage, and the presence of non-corn plants on egg deposition patterns. Females deposited significantly more egg masses on 40 DAP (pre-reproductive) corn than on early vegetative-stage plants [Sampaloc: n=437 (40 DAP), n=88 (30 DAP); BL2: n=98 (40 DAP), n=84 (30 DAP)], demonstrating a strong phenological preference, particularly in Sampaloc. The presence of non-corn plants has a negligible …

Adult Dispersal Of Field-Released Asian Corn Borer, Ostrinia Furnacalis (Guenée) (Lepidoptera: Crambidae), In Northern And Southern Philippines, Mario V. Navasero, Randolph N. Candano, Gelyn D. Sapin, Wilson N. De Panis

The Philippine Agricultural Scientist

The effectiveness of Bt corn in controlling the Asian Corn Borer (ACB), Ostrinia furnacalis Guenée, is well recognized. However, concerns persist regarding the potential development of resistance to Bt toxins by this pest. This resistance could arise from surviving ACB individuals carrying homozygous resistance alleles, potentially leading to resistant offspring if mating between resistant individuals is not prevented or minimized. To address this issue, various studies have investigated the factors that limit or facilitate resistance development. These factors include adult dispersal and mating behavior in the field, as well as ecological conditions such as weather and landscape features. However, there …

Non-Target Organisms And Terrestrial Arthropod Biodiversity In The Corn Agroecosystem: Bt Corn Beyond Acb Pest Management [Review Article], Ireneo L. Lit Jr., Merdelyn T. Caasi-Lit, Kristine O. Abenis

The Philippine Agricultural Scientist

Assessments of risks of modern biotechnology products to non-target organisms (NTOs) are required before a product can be registered and allowed for commercial production. For Bt-engineered plants, data from such studies become part of environmental risk or impact assessments that are reviewed before a hybrid can be registered and allowed for commercial planting. The approaches and methods vary among countries and researchers. Consequently, the choice of species and groups of organisms or guilds that are monitored or studied may range from narrow to broad and encompassing. The inevitability of adverse changes in agroecosystems, including those that involve the corn crop, …

Age-Dependent Reproductive Fitness And Behavioral Dynamics Of The Asian Corn Borer, Ostrinia Furnacalis (Guenée) (Lepidoptera:Crambidae), Marcela M. Navasero, Randolph N. Candano, Maricon Dp Javier, Jethro M. Navasero, Wilson N. De Panis

The Philippine Agricultural Scientist

This study evaluated the effects of parental age of the Asian corn borer (ACB), Ostrinia furnacalis (Guenée), on fecundity, egg hatchability, adult longevity, and the duration of pre-oviposition, oviposition, and post-oviposition periods using arranged mating pairs aged 1 to 5 days old. Mating behavior was also observed and documented. The highest fecundity, measured by the number of egg masses and total eggs produced, was recorded in pairings of 1-day-old males and females, indicating a positive effect of young parental age. In contrast, pairings involving 5-day-old males and females resulted in the lowest egg production, demonstrating an inverse relationship between parental …

Embodied Encounters With Plankton: Ground Truth Methods As Sites For Human-Ocean Entanglement, Clarissa Chevalier

Study of Women, Gender, & Sexuality: Faculty Publications

This article examines shifting methods of plankton research within contemporary oceanography through direct participatory engagement on a ten-day research cruise off the Santa Lucia Escarp- ment in February 2025. As a feminist visual science studies researcher, I reflect on how seasick- ness, sensory immersion, and embodied participation shaped my experience of plankton sampling and reveal the entanglement of oceanographic knowledge with its contexts. While remote sensing technologies – such as satellites, digital twins, and remotely operated vehicles – are increasingly shaping oceanography and producing intensified modes of ocean quantification, I argue that tactile, physical sampling methods remain indispensable in plankton …

Accurate tassel detection can substantially reduce both time and labor costs, offering a practical solution for large-scale agricultural management. Current studies in this area predominantly focus on training object detection algorithms to enhance prediction accuracy and efficiency. Images for this task are often captured in sequences, meaning they capture the exact location of the maize fields over time. However, existing tassel detection and counting methods typically ignore this sequential nature, …

Cattlefever: An Automated Cattle Fever Estimation System, Trong Thang Pham, Ethan Coffman, Beth Kegley, Jeremy G. Powell, Jiangchao Zhao, Ngan Le

Electrical Engineering and Computer Science Faculty Publications and Presentations

Farmers face the critical challenge of monitoring cattle well-being for both ethical and economic success, relying on signals like body temperature and facial expressions to assess their animals' health. However, these indicators have traditionally relied on human observation with manual measurement, which is time-consuming and subjective. Despite this clear need, no automated system currently exists for monitoring cattle body temperature, and available datasets remain limited in scope. To address these challenges, we make two key contributions: (i) We introduce CattleFace-RGBT, a novel RGB-Thermal (RGB-T) Cattle Facial Landmark dataset consisting of 2,300 paired RGB and thermal images (4,600 images in total), …
