  Effect of Si/Al Ratio on the Transport Behavior of Zeolitic Nanotubes.

  Muhammad Rizwan

  Carbon nanotubes are the poster child of 1-dimensional nanomaterials, but in recent years attention has spread to other chemistries such as boron-nitride and molybdenum-disulfide. The first nanotubes with zeolitic walls were recently synthesized. This new structure presents both nanoscale pores in the nanotube wall and a mesoscopic channel along the tube axis. These molecular structures have the potential to be impactful in several applications, but a fundamental understanding of how their new structure affects their adsorption and transport properties is critical to realizing their widespread use. We use molecular dynamics simulations to investigate the effect of Si/Al ratio and the associated charge defects on the adsorption and transport of different liquids within the multiscale features of the zeolite nanotube.

  Effects of Chronic Pharmacological SERCA Activation on Cognitive Behaviors, Dendritic Spine Density and Aminoacidergic Neurochemistry

  Carter J. Moore

  Intracellular Calcium (Ca2+) signaling plays a crucial role in a multitude of neuronal processes. These processes range from cell development and potentiation, to programed cell death, however they all share the commonality of being paramount in neuronal function. One key regulator of intracellular Ca2+ is the Sarco-Endoplasmic Reticulum (ER) Ca2+ ATPase (SERCA) pump. SERCA is responsible for sequestering cytosolic Ca2+ into the ER, a major site for Ca2+ storage. Due to its importance in maintaining Ca2+ homeostasis, it comes as no surprise that dysfunction of SERCA has been shown to be involved in various neuropsychiatric diseases, such as Parkinson’s Disease (PD), Alzheimer’s Disease (AD), and Schizophrenia. Consequently, drugs that affect SERCA are of high interest for future therapeutic treatments, but the role that SERCA plays in the brain and behavior is not well understood. In the context of the current study, we assessed the effects of chronic pharmacological SERCA activation using the drug CDN1163 on learning and memory processes, as well as on aminoacidergic neurochemical responses and dendritic spine density in brain regions implicated in cognitive processes in mice of both sexes.

  Effects of Digital Use on Social Wellbeing and Development

  Johnny P. Nguyen

  With the advancement of technology in the 21st century, digital usage has become more prevalent in society that the younger generations are now growing up in the presence of technological innovations. Because of this, researchers have tried to study the impact of digital technology on the social well-being of not just the youth, but people of all ages as well. This study observed the effects of digital technology on the social well-being of young adults–ages 18-25. Many studies have been conducted observing a generalized usage of digital technology on social well-being. With how advanced digital communication has become and how efficient young adults are able to use such digital modes for communication, studies have shown some disconnect when it comes to social well-being and development. This study specifically examined how communicating and connecting through digital technology affects social well-being in young adults.

  Effects of Paternal Heat Exposure and Parental Care on the Development of Offspring in Gasterosteus aculeatus

  Emma R. Borgert

  Humans are profoundly altering the abundance and distribution of organisms via climate change. In particular, warming temperatures are affecting marine and freshwater ecosystems by increasing physiological stress, limiting growth, and decreasing dissolved oxygen. With all this change occurring, an understanding of how organisms are going to cope is crucial. Transgenerational plasticity – when parental experiences alter offspring traits - can allow organisms to rapidly adapt to environmental change. Previous literature has focused on the role of maternal experiences on offspring traits, but paternal experiences are just as important. Fathers can influence their offspring in multiple ways, including changes via both sperm and paternal care behaviors. Three-spined sticklebacks, Gasterosteus aculeatus, are a small fish found in freshwater and marine ecosystems with paternal-only care. Many populations are facing the threats of drought and wildfire, making it important to understand how they will adapt to climate change. To understand how paternal heat exposure alters offspring development, I exposed parents to cool (~17°C) or warm (~20°C) water temperature and then manipulated whether fathers provided paternal care or offspring were artificially aerated; this generated offspring that received cues of heat exposure from gametes alone versus from gametes and paternal care. I found that males exposed to warmer temperatures were less colorful but provided the same amount of care overall to their offspring. Offspring of cool-temperature males were shorter than offspring of warm-temperature parents, but only when males provided paternal care. Offspring survival was not affected by parental heat exposure but was lower when offspring themselves were exposed to warm temperatures. Overall, these results suggest that heat exposure alters both paternal and offspring traits, and that the effects on offspring depend on the mechanism of paternal effects (care versus sperm).

  Energy Sector Stock Returns During Periods of Rising Fed Fund Rates: An Empirical Analysis 1999-2023

  Kathleen Mae Hattrup

  Stocks in the energy sector are highly volatile due to ongoing imbalances in the supply and demand for oil and natural gas. In this study, I examine the impact of rising interest rates and in particular, fed fund rates on energy sector stock returns. The period of analysis is from 1999-2023 within which there are four distinct periods where fed fund rates are rising. I expect positive returns to energy sector stocks in periods where the rate rise is simply due to economic growth. I expect negative returns when the rates are rising due to a policy of aggressive monetary tightening by the fed. I use the top 20 stocks by market cap in the S&P 500 energy sector to carry out my study.

  Establishing Drosophila Intestinal Tumor Models to Study Signaling Interactions that Regulate Tumor Growth

  Venolia Adjei, Sydney Ellen Anderson, Brandon Jericho Clark, Maria Theresa El Biri, Michael K. Gruhot

  Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the US, with the American Cancer Society estimating 153,000 new diagnoses and 53,000 deaths in 2023. Genetic mutations in the genes Ras, APC, and p53 occur at a high frequency in human CRC, including the activation of oncogenic Ras, loss of function of APC, and dominant negative mutations in p53. This potentially implicates dysregulation of the Ras-MAPK, Wnt, and DNA repair pathways associated with the products of these respective genes. Prior studies in patients have revealed two or more of these pathways to be dysfunctional in the majority of clinical cases, suggesting a greater need for multigenic models of CRC. To better understand tumorigenesis in the context of different genetic alterations, we have developed Drosophila melanogaster models of CRC by mispressing them individually (one-hit), in pairs (two-hit), and collectively (three-hit). Using these models, we will investigate the interactions among the aforementioned molecular pathways, characterizing the expression of pathway-specific downstream target genes, changes in the cell cycle, and tumor progression. To generate tumors in the Drosophila intestine, we misexpressed the genes under study using escargot-GAL4 (esg-GAL4), which specifically drives the expression of tumor-promoting genes in intestinal stem cells, in tandem with the heat shock-inducible FLP-FRT system. We quantified the survival rates of mutant and control flies to determine the impact of these mutations on survival. Additionally, the phenotypes and gene expression patterns of intestinal tumor cells were analyzed and compared via dissection of third-instar larvae and subsequent use of immunohistochemistry. Here, we present our preliminary data from these experiments and our progress in developing a preclinical model of CRC in Drosophila.

  Evaluating the Developmental Evidence for the Re-Evolution of Lost Mandibular Teeth in Frogs

  Madeline M. Brinkman

  Osteopilus septentrionalis, the Cuban tree frog, is a frog species that possesses upper jaw teeth but lacks mandibular teeth as an adult and is emerging as a new model organism for amphibian dental research. Through my research, I am evaluating the development and genetics of teeth in O. septentrionalis from late-stage tadpoles to froglets in order to increase our understanding of the underlying gene signals responsible for the formation of amphibian teeth, as well as the evolutionary loss and regain of complex traits. I am evaluating the presence and absence of core tooth development genes that indicate the induction and formation of teeth on the developing upper and lower jaws of O. septentrionalis. Several different genes of interest are being studied during the morphogenesis of teeth in order to investigate possible mechanisms for the re-evolution of lost mandibular teeth in G. guentheri, a species that was last seen in the wild in 1996 and is feared to be now extinct. Histology and in situ hybridization experiments will be conducted in order to answer these questions and better understand broad-scale patterns of dental diversity in frogs.

  Evaluation of Object Detection Methods in Inclement Weather

  Vatsa Sanjay Patel

  In this study, we thoroughly investigate the reliability of computer vision object detection systems in real-world traffic scenarios, particularly focusing on challenging weather conditions. Traditional evaluation methods often fall short in addressing the complexities of dynamic traffic environments, which is increasingly important with the advancement of autonomous vehicle technologies. Our research specifically examines how these algorithms perform in adverse weather like fog, rain, snow, and sun glare, recognizing the significant impact of weather on their accuracy. We emphasize that a system performing well in clear weather may struggle in adverse conditions. Our study includes detailed analyses of different architectural approaches, aiming to enhance traffic monitoring, vehicle tracking, and object tracking. Ultimately, our goal is to enhance transportation safety and efficiency by advancing robust computer vision systems for future autonomous and intelligent transportation technologies.

  Evolution and Diversity of Frog Osteoderms

  Arianna Jenelle Olivares

  Osteoderms are bony deposits that form and are embedded within the dermis layer of vertebrate skin. Osteoderms can be found in many species of tetrapods (amphibians, reptiles, and mammals), but are most well known from crocodilians, lizards, and armadillos. These structures are generally plate-like but can exhibit substantial variation in size, shape, thickness, surface ornamentation within and across species. The function of osteoderms is also variable, acting as protective armor, aiding in heat exchange and thermoregulation, or serving as a calcium reservoir. Several frog species have previously been reported to possess osteoderms, but the evolution, diversity, and function of these structures within living amphibians is poorly understood. The central aim of this study is to investigate the presence and characteristics of osteoderms among species to better understand how many times this trait has evolved in frogs and infer potential functions based on ecological data from the literature. We are using publicly available micro-computed tomography (microCT) data of all major frog groups to identify all species that possess osteoderms and to quantify osteoderm diversity (e.g., size, shape, thickness). Our results demonstrate that 1) osteoderms have evolved many times throughout the frog tree of life, 2) the location and anatomy of osteoderms vary substantially across species, and 3) these structures have arisen in species that vary dramatically in body size and ecology.

  Examining the Influence of Social Media Usage on Knowledge of Political and Social Issues

  Kaelene Samaria Walter, Alayna M. Yates

  This study will outline how social media can be a resource in educating its users considering the political climate, as well as the social activism that is present today. Previous research has helped explain the ways social media can act as a resource for learning about political and social news and occurrences, how it can spark civic engagement, and encourage political discourse and participation. However, there is still a gap that exists that this study aims to fill. This study asks how social media usage influences knowledge of political and social issues. It seeks to explain how news from social media is consumed by citizens, how it resonates with them, and whether it encourages specific participation or involvement in today’s social movements.

  Experimental Investigation of a Novel Morphing Wing Design

  Julian Alejandro Pabon

  The aerodynamic performance of a novel Fishbone Skin-Actuated-Camber (SAC) morphing wing design, which actuates its skin to change its effective camber, was studied both experimentally and numerically. Force-based experiments were conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) to compare the performance of four morphing wing designs with different hinge locations, two ideal trailing edge flap wings, and one conventional trailing edge flap wing. All test articles have an Eppler 479 airfoil, an effective aspect ratio of four, and were tested within an angle of attack range of -15° and 15 °. The novel design achieved effective camber change without any buckling, maintaining comparable aerodynamic performance to ideal flap wings at a Reynolds number of 270,000. At a Reynolds number of 400,000, the morphing shows a lower drag than the ideal flap wing. Simulations from FlightStream®, a numerical solver correlated well with experimental lift data, with the morphing wing's pressure contours indicating reduced flow separation and gradual pressure change on the upper surface when deflected.
