Analysis Of Potential Alkali Reactivity Of Aggregates In Arkansas, Brigita Dowling

2026 Research Poster Competition

Alkali Silica Reaction (ASR) is a deleterious chemical reaction in concrete that leads to the deterioration of concrete structures. This reaction occurs between minerals present in aggregates and alkalis in the cement, and produces a gel-like substance called alkali silicate gel. Gradually, these gels absorb water from the environment and expand, leading to internal stresses in the concrete. This damage results in expansion, cracking, and deformation, reducing the strength and durability of the concrete significantly. While this damage appears minor initially, eventually they can lead to the need for costly repairs or replacement of the concrete. ASR has been observed …

De excidio Troiae is a Latin text ascribed to Dares Phrygius, purportedly a soldier who had written a firsthand account of the Trojan War. Since knowledge of Greek was rare in the West during the medieval period, this text became one of the prominent sources for learning about the Trojan war. I am looking to a redaction, or version, of the text that appears to have …

Developing A Cpp-Conjugated Cas9 Library For Efficient Non-Viral Delivery To The Dmd Gene, Amie Donathan

2026 Research Poster Competition

Duchenne muscular dystrophy, or DMD, is a genetic neuromuscular disorder caused by the mutation of the DMD gene, resulting in alterations in the functionality or production of dystrophin, a protein essential to maintain muscle fiber integrity and strength. This mutation leads to progressive muscle degeneration, causing motor loss, cardiopulmonary failure, and ultimately, premature death. Gene therapies using CRISPR aim to replace the mutated gene to provide long-term correction. Although this has promise, CRISPR-based therapies use a viral vector to deliver, which presents notable challenges, such as immune problems and liver toxicity. A non-viral delivery method is a viable approach, but …

A Bayesian Late-Fusion Supportability Framework For Rare-Disease Severity Prediction In Glut1 Deficiency Syndrome, Jordan M. Rodriguez

Mathematics Dissertations

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is a rare neurometabolic disorder with heterogeneous neurological and developmental severity. Because patient-level severity is not observed as a single validated outcome, this dissertation develops a Bayesian late-fusion supportability framework for constructing and predicting an ordered latent severity phenotype from clinical, genetic, and EEG-derived evidence. The primary target was constructed in a larger clinical cohort using age-5 symptom burden and learning cognition, then assigned to an aligned multimodal prediction cohort. Target-defining variables were excluded from supervised predictors, and models were evaluated using patient-exclusive cross-validation with training-fold preprocessing and fold-wise EEG PCA.

The primary …

Blood Flow Regulates Metabolism In Hematopoietic Development, Pamela L Wenzel

Faculty, Staff and Student Publications

Blood flow modifies oxygen availability and biomechanical forces within the vasculature of the embryo as the hematopoietic system develops. The aorta-gonad-mesonephros (AGM) envelops the largest artery in the body and is a critical site for the emergence of hematopoietic stem cells (HSCs). Herein, I discuss the role of hypoxia-inducible factors (HIFs) and force as determinants of metabolism and fate determination. To address the effects of blood flow on hematopoietic development, I employ mouse embryo models and biomimetic culture. Real-time cell metabolic analyses show that oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) are altered by flow in cultures of …
