  • A Convolutional Neural Network for Atmospheric thermal detection in Unmanned Aerial Vehicles by Joshua Riojas

    A Convolutional Neural Network for Atmospheric thermal detection in Unmanned Aerial Vehicles

    Joshua Riojas

    Birds utilize atmospheric thermals, which are vertical columns of warm air generated by the uneven heating of the Earth's surface, to conserve significant energy during flight, particularly over long migratory routes. This natural energy-saving strategy presents a compelling model for enhancing the endurance of Unmanned Aerial Vehicles (UAVs). This study aims to apply this biomimetic concept to UAVs to conserve onboard energy and thereby extend the drone's operational flight time. The primary objective of this research is to develop and validate a method for a UAV to autonomously detect and utilize atmospheric thermals using a machine learning model to predict the presence of these updrafts in real-time. A Convolutional Neural Network (CNN) model was developed to predict whether the UAV is in an atmospheric thermal based on vertical error derived from its XYZ coordinates. Furthermore, the model incorporates gyroscope data (roll, pitch, and yaw) to determine the UAV's position and orientation within the thermal. The quantitative analysis revealed that the CNN model accurately predicted the presence of atmospheric thermals by correlating vertical error with the UAV's spatial coordinates and gyroscope data. The successful implementation of the CNN demonstrates that it is feasible for a UAV to autonomously identify and orient itself within atmospheric thermals using standard onboard sensors. This step advances energy-efficient UAVs mimicking bird soaring, using natural updrafts to extend flight time, reducing battery dependence, and enabling long missions like monitoring, surveillance, and sensing.

  • AI-Powered Content Strategy Implementation: Evaluating Effectiveness for Startups in Four Industries by Lilian Hernandez Peregrino

    AI-Powered Content Strategy Implementation: Evaluating Effectiveness for Startups in Four Industries

    Lilian Hernandez Peregrino

    Startups face significant challenges in today’s rapidly evolving digital marketplace, particularly when competing with larger firms that can more readily absorb risk and adapt to technological change. Although established frameworks such as the Business Model Canvas (BMC) and Joe Pulizzi’s Content Inc. model provide valuable guidance for early-stage ventures, they do not fully address the demands of modern marketing in an era increasingly defined by artificial intelligence (AI). This qualitative multiple-case study examines how an AI-enhanced Content Inc. model can support more effective content marketing strategies for startups operating in four distinct industries: food, custom software development, outdoor consumer products, and grant management software. Using the BMC as a contextual framework, this research focuses on founders’ firsthand experiences and feedback to understand how AI tools influence the development and implementation of content strategies. Semi-structured interviews were conducted with the founders of each participating startup to capture insights on current practices, challenges, and the practical application of AI within a content-driven approach. Cross-case analysis was then used to compare how each industry adapted to the AI-enhanced model, highlighting which sectors may be best positioned for successful implementation. While the study’s findings are limited by its small sample size and an eight-week research period, the results aim to offer actionable insights for startups seeking to build sustainable growth through more efficient, technology-supported marketing strategies.

  • AI vs. Human Imagery in Advertising: Do Consumers Care? by Belyn Thompson

    AI vs. Human Imagery in Advertising: Do Consumers Care?

    Belyn Thompson

    Digital marketing has been evolving at rapid speed with Artificial Intelligence (AI) emerging through generative AI creating visuals for advertisement. Yet little is still known about how consumers truly feel about this change. This study explores whether AI-generated images truly differ from human-created photography in the eyes of everyday buyers, focusing on three key metrics: purchase intent, aesthetic appeal, and perceived realism. Over a roughly two-week window in June 2025, 199 U.S. adults on Amazon Mechanical Turk (MTurk) evaluated 24 product images: technology, food, apparel, and cosmetics. Each is presented in both AI “sibling” and original photographer versions under varying disclosure labels. Participants also completed preliminary questions about AI familiarity and brand trust. Results showed that, in most categories, consumers did not penalize AI visuals; only in apparel did the correct image disclosure trigger a marginally significant 0.499-point drop in purchase intent (p = .015). These findings suggest that, beyond novelty, high-quality AI imagery may be able to compare against human-created photos, except in contexts where authenticity and craftsmanship are especially prized. Marketers can therefore leverage AI as a creative collaborator and tool to help aid company success if used intentionally. Future work may investigate long-term AI exposure effects, delve into cross-cultural differences, and explore disclosure and other factors in relation to consumers’ perception and overall attitude.

  • Detection of Catalytic Intermediates in the RuBisCO Mechanism using 13C and 31P NMR by Julia Martinez

    Detection of Catalytic Intermediates in the RuBisCO Mechanism using 13C and 31P NMR

    Julia Martinez

    Ribulose 1,5-bisphosphate carboxylase/oxygenase, or RuBisCO, is an enzyme which plays an essential role in carbon fixation and plant metabolism. While RuBisCO is considered the most abundant protein on the planet, its catalytic mechanism is still not completely understood. RuBisCO is notoriously slow and exhibits low specificity for CO2 over O2, leading to energetically wasteful photorespiration. Efforts to improve RuBisCO’s catalytic efficiency have been hindered due to an incomplete picture of key transient intermediates involved in the reaction. Acid quenched single turnover reaction experiments in combination with 13C and 31P Nuclear Magnetic Spectroscopy (NMR) offers a promising approach for the characterization of RuBisCO’s reaction pathway at a molecular level, including the detection of short-lived intermediates. In this study, we present an initial framework for applying NMR techniques to probe the RuBisCO catalytic pathway. We assess the feasability of detecting catalytic intermediates under varying experimental conditions, including cofactor availability and reaction time. Our preliminary data reveal both the promise and the technical challenges of this approach, including issues related to sensitivity, intermediate lifetimes, and sample conditions. While the direct observation of individual intermediates remains a target for future work, these findings demonstrate the potential of NMR as a tool for investigating RuBisCO’s catalytic mechanism and provide a technical foundation for future research aimed at the characterization of reaction intermediates.

  • Do Female Belugas Aid in Sexual Development of Juvenile Males? by Alondra-Sophia Martinez

    Do Female Belugas Aid in Sexual Development of Juvenile Males?

    Alondra-Sophia Martinez

    Reproduction is essential for every species to maintain their population. Observations of beluga (Delphinapterus leucas) reproduction in the wild and managed care have been limited, with few recordings of sexual behavior. Most data of sexual/sociosexual behavior have been of male-onmale interactions. This leaves a substantial gap in male and female interactions, specifically between adult females and juvenile/immature males. Footage collected between 2013 and 2025 were collected from SeaWorld, San Antonio, housing 17 beluga whales throughout these years, eight females (seven adults, one juvenile female), and nine males (two adults, seven juveniles). From about 21 hours of data, this study showed that adult females did initiate in sociosexual and sexual interactions with juvenile males during the breeding season. Adult females initiated more sociosexual interactions when there were fewer males in a social group but appeared to initiate more sexual interactions when there were 3-4 juvenile males. These social interactions suggest that adult females may potentially play a critical role in the sociosexual/sexual development of juvenile males.

  • Do Young Beluga’s Play More or Less Than Adult Beluga’s? by Winter Saldaña

    Do Young Beluga’s Play More or Less Than Adult Beluga’s?

    Winter Saldaña

    The presence of play is used as an indicator of well-being in many species including belugas. The purpose of the current study was to explore if object play exhibited by belugas varied between young and adult animals. Within the year 2023, 79 archived videos of the belugas at SeaWorld Texas were selected and coded for object play, which included water, enrichment devices, and organic material. Adult and young belugas engaged in a similar amount of play bouts and actions during object play. These findings suggest that belugas in managed care experience positive well-being as indicated by the presence of object play but do not address how object play emerges over development. Future research should explore the emergence of play to examine how development and experience influence actions with objects.

  • Leveraging MATLAB for Genomic Analysis of Alzheimer’s Disease Risk Genes in GWAS Datasets by Rolando Ramos

    Leveraging MATLAB for Genomic Analysis of Alzheimer’s Disease Risk Genes in GWAS Datasets

    Rolando Ramos

    Alzheimer’s disease (AD) is a complex neurodegenerative disorder influenced by both environmental and genetic factors. My research emphasizes a bioinformatics pipeline using MATLAB, a data analysis tool, to analyze genome-wide association study (GWAS) data intended to pinpoint key genetic variants involved in AD. This method allows for large-scale genomic interrogation while minimizing manual processing errors. We are particularly interested in loci linked to well-established risk genes such as APOE, BIN1, and TREM2. Publicly available datasets, including the Gene Expression Omnibus (GEO) and Alzheimer’s Disease Neuroimaging Initiative (ADNI), are being processed to extract and purify relevant genotypic and expression data. Mat lab serves as a versatile engine to organize, clean, and statistically evaluate the data, integrating functions from the Bioinformatics Toolbox to conduct SNP filtering, allele frequency analysis, and genomic variant visualization. Efficient comparison between control and AD samples are displayed through effective methodology. Differential expression and variant patterns support findings reported in current literature. Insights from this analysis may reveal patterns that inform both diagnostic strategies and therapeutic research. Early identification of high-risk alleles allow for more personalized and proactive clinical interventions. This approach not only streamlines data analysis but also provides a standardized and scalable framework for future investigations. We aim to capture a deeper understanding of the molecular basis of AD and support efforts in preventive health by identifying early genetic risk factors. This research underscores the potential of computational biology in advancing precision medicine and demonstrates how technical tools like MATLAB can be applied in genomic medicine.

  • Mica Productions: The Sad Truth Behind Cosmetic Corporations’ Impact on Children’s Health in India by Nyleen Benavides

    Mica Productions: The Sad Truth Behind Cosmetic Corporations’ Impact on Children’s Health in India

    Nyleen Benavides

    Mica is a shiny silicate mineral found in granite, crystals, or other rocks. Its shiny and reflective property has attracted the eyes of many cosmetic corporations. Due to high rates of unemployment and poverty in Asian countries such as India and its Jharkhand region, corporations have taken over and manipulated the exportations of mica. These regions carry out illegal child labor in mica mining sites that are not only hazardous to children, but the economy and ecosystem around them. Previous research has shown how cosmetic corporations use mica as one of their main ingredients for shiny pigmentations within their products, however, there is limited research that has indicated the links between child labor and the cosmetic industry. This research examines the effects that cosmetic corporations have on children in India. Specifically, it seeks to discuss why the high demand of mica increases child labor and negatively impacts the health, economic, and social wellbeing of children. By analyzing secondary sources such as peer reviewed articles, reports, and policies in India, this study will contribute to a better understanding of exploitative child labor and provide alternative ways corporations can mine mica that allows a more effective quality of life for children and their families.

  • Modeling the Effects of Plasma Etching Parameters using MATLAB by Joshua Mendez

    Modeling the Effects of Plasma Etching Parameters using MATLAB

    Joshua Mendez

    This paper presents a study of plasma etching in tungsten diselenide (WSe2), a transition metal dichalcogenide with promising applications in nanofabrication. We investigate the effects of ion flux, incidence angle, and energy distribution on etch profiles by developing a custom MATLAB simulation framework informed by literature-derived experimental data. The simulation models trench geometry evolution over time and includes visualization of etch depth in 1D, 2D, and 3D. Preliminary results qualitatively reproduce anisotropic etching trends reported in the literature. This work aims to provide a scalable computational tool to aid understanding and optimization of plasma etching parameters for emerging nanomaterials.

  • Resisting “Chicana and Latina Syndrome”: Preserving Difference across Feminist Accounts of the Self by Amely Logan

    Resisting “Chicana and Latina Syndrome”: Preserving Difference across Feminist Accounts of the Self

    Amely Logan

    This paper considers feminist Chicanx and Latinx philosophers’ theories of the self and takes up the call that we must resist the tendency to clump Chicanx and Latinx identity together. In this paper, I respond to the work of Latina feminist theorist, Carmen Lugo-Lugo, in which she addresses the dangers of homogenizing Chicanx and Latinx identity and insists that we must take seriously the differences between the two identities. While more attention has been given to Chicanx and Latinx work in recent philosophical literature, little has been done to track distinctions between Chicanx and Latinx theories of the self. I consult the works of Latinx and Chicanx feminist philosophers, including Mariana Ortega, María Lugones, Gloria Anzaldúa, Jacqueline Martinez, Norma Alarcón, and Linda M. Alcoff, in order to demonstrate the differences between their descriptions of lived experience and theories of the self. My account reveals that Chicanx and Latinx theories of the self-differ in three major ways: (1) in the history that gave rise to the term Chicanx, (2) in the differences between Latinx and Chicanx lived experience, and (3) in the worlds that Chicanxs and Latinxs belong to. This paper thus illustrates how, by failing to take seriously these differences, we risk further homogenization and/or erasure of multiply-marginalized selves.

  • Sacred Silence: Religion and Intimate Partner Violence by Miranda Ibarra

    Sacred Silence: Religion and Intimate Partner Violence

    Miranda Ibarra

    This study investigates the Intimate Partner Violence (IPV) within the St. Mary’s University community. A survey distributed via institutional email collected responses addressing both direct and indirect experiences related to IPV. The analysis explores associations between religiosity, permissive IPV attitudes, and belief in divine control; results indicate no statistically significant relationship. Additionally, the study examined the connections between religiosity, IPV victimization, and frequency of perpetrated abuse, finding no significant associations with religiosity but a significant association between victimization and perpetration frequency. Limitations include the use of a convenience sample, restricted generalizability, and potential self-report bias, which may affect the reliability of the data.

  • Separate But Found: An Anthropological Analysis of Toni Morrison’s Beloved by B. Haynes

    Separate But Found: An Anthropological Analysis of Toni Morrison’s Beloved

    B. Haynes

    Separation is the ideal solution for African American women to recover their humanity and build a future in America, according to Toni Morrison's Beloved. African American women assimilating with their White oppressors is not advantageous to their survival, and this is revealed through the extremely different experiences that Baby Suggs, Sethe, Beloved, and Denver have had with Whiteness, experiences that have irrevocably altered their lives and viewpoints. These women understandably harbor a strong hatred for their oppressor and would be unable to foster a coexistence with them, given their suffering after being the victims of sexual assault, lynchings, hard labor, substandard living circumstances, and death regularly. To demonstrate the methodical methods in which women are dehumanized under Whiteness and the reasons for the separation, this essay examines each lady, their most pivotal moment, and their experiences within the book through Agamben's philosophy.

  • The Cellular Landscape of Alzheimer’s Disease: A Review of Repair, Response, and Resilience by Mark Sanchez

    The Cellular Landscape of Alzheimer’s Disease: A Review of Repair, Response, and Resilience

    Mark Sanchez

    Neurodegeneration, like that seen in Alzheimer’s disease, is generally characterized by the progressive loss of cognitive function with widespread cellular dysfunction. Hallmark features of Alzheimer’s disease include the accumulation of amyloid -beta, tau pathology, DNA damage, and disruptions in glial cell function. Despite this knowledge, the mechanisms by which specific brain cell types contribute to or resist neurodegeneration remain unclear.

    This review synthesizes findings from over twenty recent studies to explore how astrocytes and neurons respond to injury and chronic pathology, with special attention given to astrocytic vulnerability, DNA repair regulation, and the intersection between tau accumulation and chromatin structure. We organize our content around three central themes: cell type/location, cell-specific response dynamics, and cellular resiliency. In doing so, we examine how DNA repair pathways, oxidative stress defenses, and protein aggregation intersect to shape disease outcomes. Across each of these themes, we highlight discrepancies in results, identify gaps within the literature, and offer potential avenues for clarification of causal mechanisms and therapeutic targets. By framing the progression of neurodegenerative mechanisms through a cellular lens, we propose insights into new foundations for models of brain resilience and cellspecific therapeutics.

  • The Coloniality of Gender and Class: Analyzing Maria Lugones Decolonial Feminism by Silvia E. Zamora

    The Coloniality of Gender and Class: Analyzing Maria Lugones Decolonial Feminism

    Silvia E. Zamora

    This paper examines Maria Lugones' theory of the colonial/modern gender system as a foundation for her framework of decolonial feminism. Lugones argues that because of colonialism, our society has gendered hierarchies. These hierarchies dehumanize Indigenous women and enforce European heterosexual norms. Drawing from Anibal Quijano’s concept of coloniality of power, Lugones expands the idea with the coloniality of gender. She emphasizes how race, gender, and sexuality are constructed by colonial violence. Lugones offers a powerful critique of traditional feminism’s Eurocentric bias. This paper aims to investigate the overlooked concept of class oppression to achieve a decolonial feminism. Applying the work of Iris Marion Young’s theory of structural injustice and the concept of the “Five Faces of Oppression, "specifically exploitation and powerlessness, this work shows how economic hierarchies intersect with colonial and gendered structures. A case study on women garment workers in Bangladesh is used to illustrate how global capitalism reinforces the gendered labor hierarchies that are rooted in colonialism and patriarchy. This expanded framework accounts for the lived experiences of marginalized women and offers a more inclusive approach to feminist resistance.

  • The relationship of Phosphatidylethanol and Cholesterol in Non-Human Primates by Samantha Nguyen

    The relationship of Phosphatidylethanol and Cholesterol in Non-Human Primates

    Samantha Nguyen

    Background: Phosphatidylethanol (PEth) is a metabolite of ethanol, therefore a direct detector of alcohol in the human body, which is used to identify and monitor severity of alcohol events.

    There are standardized levels that indicate little to heavy drinking, ranging from 0-200+. PEth levels, however, are variable amongst humans. Non-human primates such as monkeys have been proven to produce PEth, being a viable model to test for these sources of variability amongst humans. In this study, we examined the relationship of cholesterol and lipid proteins to an abundant PEth homolog [16:0/18:01] in non-human primates existing in both humans and monkeys.

    Methods: 6 monkeys were given unrestricted access to 4% ethanol solution and water 20 hours/day for 14 days. Whole blood samples were taken afterwards and then analyzed for Peth homolog [16:0/18:01] using high performance liquid chromatography (HPLC) as well as for total cholesterol, HDL, and LDL using an AF HDL & LDL/VLDL assay kit (ELISA).

    Results: The results show that 1) PEth to lipid counts have a better accuracy when read immediately after alcohol consumption, compared to after 2 weeks; 2) the PEth/HDL had the highest correlation when reflected in volume intake (amount); 3) PEth/LDL had the highest correlation when reflected in concentration (dose).

    Conclusion: Results suggest PEth to lipid ratios have a stronger correlation when blood is tested more recently compared to over time, as well as when PEth is compared to recent alcohol intake alone. More research needs to be conducted to better understand the relationship between phosphatidylethanol and lipid interaction.
