The Vegetated-Canopy Roughness Sublayer Through A Tke-Budget Lens, Giulia Salmaso, Raul Bayoan Cal, Marc Calaf

Mechanical and Materials Engineering Faculty Publications and Presentations

It is well understood that vegetated canopies perturb the atmospheric flow within and immediately above the canopy, deviating from the inertial sublayer (ISL) regime characteristic of non-vegetated rough surfaces. Only above a certain height, denoted as the roughness sublayer height (RSL, 𝑧∗), do these flows return to ISL-like behavior. This distinction is critical, as parameterizations in Earth System Models (ESMs) are typically developed for ISL flows. Yet, most 𝑧∗ estimates stem from studies over flat, homogeneous canopies and may be biased. In contrast, little is known about 𝑧∗ in non-homogeneous or heterogeneous canopies that are not of agricultural interest, with …

Spell: A Scalable Nlp Method Using Regular Expressions And Large Language Models For Clinical Information Extraction, Kathryn J Gray, Vesela P Kovacheva

Faculty, Staff and Students Publications

Background and objectives: Electronic health records (EHRs) contain valuable information for research and decision-making, but much resides in unstructured notes that are challenging to analyze at scale. We developed SPELL (Snippet-Primed rEgex LLM Pipeline), a scalable natural language processing workflow that combines regular-expression-based snippet retrieval with locally hosted large language model (LLM) inference to extract structured variables from large collections of clinical narratives.

Methods: SPELL uses task-specific regular expressions to retrieve short context windows ("snippets") from unstructured texts and applies task-prompted LLM inference on snippets rather than full documents. All processing occurs within institutional computing environments. Accuracy was evaluated on …

Cadherin-11 Regulation Of Type Ii Alveolar Epithelial Cells During Pulmonary Fibrosis, Mesias Pedroza, Sarah To, Jennifer Smith, Tingting W Mills, Thandiwe Chavula, Harry Karmouty-Quintana, Sandeep K Agarwal

Faculty, Staff and Students Publications

Type II alveolar epithelial cell (AT2) injury has been hypothesized to contribute to pulmonary fibrosis. Cadherin-11 (CDH11) is a mediator of fibrosis and is upregulated on AT2s during lung fibrosis. Herein, the regulation of AT2 by CDH11 during pulmonary fibrosis was investigated. CDH11 levels were increased in lung samples from patients with idiopathic pulmonary fibrosis compared with those from healthy controls. CDH11 expression was inversely correlated with lung function. Cdh11-deficient mice were compared with wild-type mice in the intraperitoneal bleomycin model (IP BLM), and the role of AT2 was investigated using Cdh11 floxed-SPC-Cre mice and in vitro techniques. In …

Faculty, Staff and Students Publications

Muscle-invasive bladder cancer (MIBC) is clinically heterogeneous, and current molecular subtyping does not capture the spatial organization of tumor states and microenvironmental context. In this study, we construct a spatial atlas of MIBC by integrating spatial transcriptomics from 22 tumors with matched bulk RNA and whole-exome sequencing data. We identify a continuous, spatially organized luminal-to-basal axis within individual tumors that is associated with greater chromosomal instability and transcriptional plasticity. Luminal tumor cores are enriched for FGFR3 and NECTIN4, whereas basal-like states localize toward invasive margins and are associated with elevated EGFR signaling, epithelial-mesenchymal transition, genomic instability, immune infiltration, and greater …

Dynamics Of Coral Rubble On Reef Flats: From Individual Clast Mobilisation To Rubble Strip Morphological Change, Aitana Gea-Neuhaus, Tim Scott, Gerd Masselink, Ana Vila-Concejo, Paul S. Kench, Mathilde Lindhart, Floortje E. Roelvink, Tom Hamilton, Ke Lin, Xianfeng Wang

School of Biological and Marine Sciences

Rubble strips are shore-normal, elongated deposits on coral reef flats, composed of variably sized and shaped mobile coral clasts, which can contribute to the sediment supply on exposed low-lying coral reef islands. As climate change-driven ecological and physical disturbances increasingly impact coral reef systems and associated landforms, understanding the processes and controls governing their morphodynamics is critical. At an exposed intertidal rubble strip in Huvadhu Atoll, we examined: i) the morpho-sedimentological characteristics; ii) short-term (days-weeks) clast mobility using tracer experiments with in situ current and wave measurements; iii) intra-annual morphological changes using repeated UAV photogrammetric surveys; and iv) deposit age …

Bright Shadows, Fresh Appeal: How Shadow Brightness Shapes Perceptions Of Fresh Products, Jonghee Kum, Hyewon Cho, Hyejin Lee

Asia Marketing Journal

This study examines how shadow brightness (light vs. dark) influences consumer responses to fresh products across four studies. Studies 1a and 1b demonstrate that consumers evaluate fresh products with light shadows more favorably compared to those with dark shadows. Study 2 identifies the underlying mechanism, showing that light shadows increase perceived wholesomeness, which positively affects consumer responses. Study 3 tests a boundary condition, revealing that the positive impact of light (vs. dark) shadows is pronounced for uncooked products but reduced for cooked products. These findings contribute to a better understanding of the influential role of visual elements in shaping consumer …

Smart Tourism Technology And Sustainable Tourism: Creating Vivid Memories To Drive Tourists' Behavioural Intention, Hatane Semuel, Regina Jokom, Trixie Nova Bella Tandijaya, Sienny Thio

Asia Marketing Journal

This study examines the impact of smart tourism technology and sustainable tourism on tourists' behavioural intention, with vivid memory as a mediating variable. Earlier studies have investigated smart tourism technology and sustainability separately, but there is a lack of understanding of how these two perspectives interact with memory theory to influence tourist behaviour. To address this gap, a survey was conducted involving 742 tourists across four major Indonesian cities, and the data were analysed using path analysis with SmartPLS. The findings show that sustainable tourism directly and indirectly shapes behavioural intention, while smart tourism technology influences it only indirectly through …

Defining Teacher Envelopment: A Non-Aristotelian Approach To Meta-Practices In The Philosophy Of Teacher Education, Rob Blom

Journal of Contemplative and Holistic Education

The late Jonathan Neufeld argued that redefining teacher development required meta-practices, yet he never defined what these meta-practices were. To define them rigorously requires grounding teacher cultivation practices within coherent structures of truth capable of withstanding philosophical scrutiny—a challenge intensified by post- truth discourse that flattens epistemological depth in secularised educational theory. This paper advances a theory of teacher envelopment to complement conventional teacher development through identifying mindfulness and discernment as foundational meta-practices grounded in non-Aristotelian systems. The framework rests on three interrelated concepts: (1) truth paradigms encompassing contemplative, articulatory, and embodied dimensions; (2) epistemological depth as extensional practices that …

Hear My Voice As Who I Am: Theorizing The Essence Of Poetry In Holistic Global Citizenship Education, Shue-Kei Joanna Mok

Journal of Contemplative and Holistic Education

Poetry as an imaginative language art has long been perceived as the core of humanity, the foundation of human advancement (Arnold,1880; Rorty, 2007). By composing, critiquing, and sharing/performing poems, not only does the process enrich and deepen one’s relationship to oneself, understanding and reflecting on the contextual, historical, cultural, social, and creative backgrounds of the poems and poets allows one to have greater connections with the broader environment across temporal, spatial, and social dimensions with human and non-human beings.

This paper first frames the core concepts and values of global citizenship from a Confucius perspective to emphasize the significance of …

Phenotypic Variation Between Surface And Cave-Adapted Poeciliids And Its Effect On Metabolism, Karch Knipp, Michael Tobler, Soren Johnson

Undergraduate Research Symposium

Cave-adapted organisms often exhibit pronounced morphological changes relative to their surface counterparts, a phenomenon known as troglomorphy. In Poecilia mexicana (Atlantic molly), these differences include variation in coloration between surface and cave populations. Troglobitic organisms also typically exhibit reduced metabolic rates, likely as an adaptation to environments with low primary productivity. This makes P. mexicana an ideal system for investigating the evolution of metabolic traits. In this study, we leveraged variation in coloration among cave-dwelling mollies to examine potential associations with resting metabolic rate (RMR). Coloration was quantified using PCR values, and individuals were categorized as “yellow” or “non-yellow.” We …

The Impact Of Caffeine On Bumble Bee Hunger, Hallie Chapman, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Bumble bees (Bombus impatiens) are crucial pollinators, responsible for pollinating multiple native plants and agricultural crops. Caffeine, which is classified as a stimulant, is present in some of these plant species at varying levels. Alterations in bumble bee cognition, including motivation, learning, and hunger, have been associated with caffeine intake. This study explored the impacts of caffeine on the bumble bee behavior on a biological level. While previous research has examined caffeine’s effects on cognition and learning, fewer studies have investigated its effects on hunger at the level of individual bees. Bumble bees, identified with numerically labeled tags, …

Caffeine Concentration: An Analysis On Bumble Bee Foraging Efficiency, Carson Leonard, Becky Hansis-O’Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Caffeine (trimethylxanthine) is a synthetically and naturally produced stimulant that has been shown to elicit an effect on the central nervous system of humans as well as invertebrates. Although the exact mechanisms by which caffeine alters biological processes in invertebrates are still being investigated, its physiological and behavioral effects have been extensively documented. Naturally occurring caffeine is produced by certain flowering plants, including cocoa and tea species, and has been shown to influence invertebrate behavior, particularly cognitive performance and foraging patterns. In pollinating insects, the exposure to caffeine in floral nectar may affect how pollinators evaluate, select, and revisit food …

Tarantulas Can Use Black And White Cues In A Discrimination Learning Task, Jordan Kolinski, Becky Hansis O'Neill, Amiee Dunlap

Undergraduate Research Symposium

Animals use vision to perceive light, shapes, colors, and movement. Many animals that have poor vision are understudied. The purpose of this experiment was to study color vision in tarantulas (Brachypelma hamorii). Researchers have found genes associated with color vision tarantulas, but no behavioral experiments have been done on this topic. Previous research has also shown that tarantulas can see polarized light. In this experiment, we wanted to know if tarantulas could use visual cues to move away from a noxious stimulus - vibration. There were twelve tarantulas being tested in this experiment for between twelve and fifteen …

Relationship Between Morphological And Behavioral Laterality In Astyanax Mexicanus, Allison Lendman, Michael Tobler, Erik Johnson

Undergraduate Research Symposium

Populations within the Astyanax genus have experienced extreme differences in environment, leading to distinct morphological adaptations. The cave populations of these fish are eyeless and have acquired fixed, cranial asymmetries. We explored a possible relationship between this physical asymmetry and behavioral laterality. We tested 28 adult fish, 14 male and 14 female, from the Pachón cave in controlled behavioral trials. We found that both sexes demonstrated behavioral laterality, observed as a consistent left-turn bias in these trials. This supports the hypothesis that these populations display behavioral laterality that is correlated to their physical asymmetries. Ongoing research comparing behavioral patterns in …

Under The Surface: Human Disturbance Reduces Species Richness In Glade Microhabitats, Maddie Smith, Becky Hansis-O'Neill, Aimee Dunlap Phd

Undergraduate Research Symposium

Human disturbance can alter microhabitats in ways that affect biodiversity, especially in sensitive ecosystems like glades where many animals rely on rocks for thermoregulation and refuge. This study examined how rock displacement by human activity influences species richness and community composition in glade habitats at Shaw Nature Reserve and Victoria Glades Conservation Area. We hypothesized that disturbed rocks would be less suitable for wildlife and would support fewer species. From September to November 2025, about 30 rocks per site were pseudo-randomly selected and monitored. Each rock was classified as displaced or nondisplaced, and all organisms found beneath them were recorded. …

Transposon Mutagenesis Identifies Genes Involved In Salicylate-Induced Regulation Of Cyclopropane Fatty Acid Expression And Membrane Lipid Modification In Salmonella Enterica Serovar Typhimurium, Presconique Cooper, Taiwo Iromini, Lon Chubiz

Undergraduate Research Symposium

Salicylate, a topical antiseptic and non-steroidal anti-inflammatory drug (NSAID), is known to induce physiological stress adaptation in bacteria. One such adaptation involves the cyclopropanation of unsaturated membrane fatty acids, a process that enhances membrane integrity under stress conditions. In Salmonella enterica serovar Typhimurium 14028S, the cfa gene encodes cyclopropane fatty acid synthase, a key enzyme that modifies membrane lipids to promote stress tolerance. To understand regulatory mechanisms underlying salicylate induction of cfa expression, a lacZ reporter system was employed to screen a library of transposon mutants for altered cfa promoter activity. Mutant 243 showed a pronounced 5-8 fold decrease in …

A Unified Pipeline For Network-Based Gene Pattern Discovery, Siddhartha Reddy Pullannagari, Sharlee Climer

Undergraduate Research Symposium

Large-scale genetic datasets from diverse diseases, including cancer and neurodegenerative disorders such as Alzheimer’s disease, provide unprecedented opportunities to study disease pathogenesis and generate hypotheses for drug discovery. However, identifying meaningful genetic interaction patterns within these datasets remains challenging due to combinatorial relationships amongst genes and heterogeneous biological underpinnings across subtypes. This project systematically analyzes a diverse collection of omics datasets (e.g., GSE44076, GSE97810, GSE127711, GSE112679) obtained from the NCBI Gene Expression Omnibus (GEO), spanning multiple biological conditions and data types. We use a unified computational pipeline designed to handle variation in dataset size, structure, and context. The steps in …

Are You In Control? How Timing And Severity Of Trauma Shape Perceived Self-Agency, Kinsey L. Henrichsen, Caleb A. Sanders, Carissa L. Philippi

Undergraduate Research Symposium

Exposure to trauma may alter self-agency, or the sense that one can influence outcomes and exert control over life circumstances. The present study examined whether the timing and severity of traumatic experiences are associated with perceived self-agency across development. Based on prior research, we tested whether trauma occurring earlier in life would be associated with lower self-agency than trauma occurring later, and whether greater trauma severity would be associated with further reductions in perceived control. Participants were 116 trauma-exposed adults (38 male; 78 female) who reported trauma exposure using the Life Stressor Checklist. Trauma variables included age at earliest trauma, …

Enantioselectivity Of The Photochemical Continuous-Flow Isomerization Of Humulones, Gregory M. Giovine, Trevor Smith, Bruce Hamper

Undergraduate Research Symposium

Humulones, the primary natural product present in the historically significant hop flower, represent a largely unexplored candidate for structure-based pharmaceutical design.  Showing promising biological activity as an anti-bacterial and anti-inflammatory agent, humulones are of interest both for their bioactive properties and for their long-established tolerability and natural abundance.  Humulones undergo a characteristic isomerization reaction, where the six-membered substituted phloroglucinol ring contracts to a five-membered ring isohumulone, under a variety of conditions, including those enabled by brewing conditions (thermal, metal-catalyzed) and by exposure to UV light.  Optimization of the photocatalyzed isomerization of n-humulone to n-isohumulone in flow conditions resulted in a …

Wasps Survive Tornadoes, But It Impacts Nest Growth, Natalie Cummins, Sara E. Miller

Undergraduate Research Symposium

As the climate becomes more variable, extreme weather events become more common. Last May, St. Louis was hit by an EF-3 tornado. Many areas of the city suffered 90-150 mph winds and severe property damage. We knew there were established paper wasp populations in the affected areas, and so we took this opportunity to monitor emerging nests throughout the summer and fall in both tornado-affected and non-affected areas to observe any possible effect on their nest growth rate and overall size. There is currently very little literature investigating the response of insects to natural disturbances, like tornadoes. Additionally, most studies …

Building Genetic And Culturing Tools For The Understudied Soil Bacterium E. Flagellatus, Aaron Butler, Brenda Pratte, Lon Chubiz

Undergraduate Research Symposium

Soil bacteria play essential roles in nutrient cycling, yet many abundant groups remain poorly characterized due to challenges in cultivation and genetic manipulation. One such organism is Edaphobacter flagellatus, a member of the Acidobacteriota frequently detected in soil environments but lacking well-developed experimental tools. To address this limitation, our laboratory has generated a genome-wide mutant library using the Tn5 transposon, enabling random disruption of genes across the population.

This project aims to establish culture conditions necessary to support the use of this library for functional genomic studies. In particular, defined minimal media can impose selective pressures that reveal …
