Global Time-Resolved Measurements Of Inlet/Isolator Unstart Induced By Mass Injection, Andrew N. Bustard, Benjamin L. Bemis, Aaron Marques, Matthew J. Zahr, Thomas J. Juliano

Publications

The inner surface pressure of an axisymmetric inlet/isolator model was measured using anodized-aluminum pressure-sensitive paint (PSP) viewing through cast acrylic. Temperaturesensitive paint was utilized to correct for the PSP’s temperature sensitivity. The model was tested under Mach 5.7 flow at 𝑹𝒆 = 7.1 ×106 /m under conventional noise conditions. Transverse jet injection with jet-to-inlet mass-flow ratios up to 0.8 was used to induce unstart in the inlet/isolator. Background-oriented schlieren visualization of the inlet shocks was collected simultaneously with the PSP to determine when the inlet unstarted. Computational fluid dynamics results were used to determine off-wall flow structures and quantify approach …

Getting Tolkien Right: Middle-Earth In The National Review, Craig Franson

Journal of Tolkien Research

J.R.R. Tolkien’s The Lord of the Rings entered Anglo-American popular consciousness as an emblem of 1960s, leftist youth culture, but the novel slowly gained currency across the political right. In the U.S., conservative intellectuals published book notes and articles on Tolkien’s writing in their movement’s leading journals, gradually habituating their readers to seeing the once-obscure English fantasist as a canonical writer for American conservatism. The most prominent of these journals was William F. Buckley’s National Review, which recurrently promoted Tolkien’s writing and offered a distinctly partisan interpretation of his texts. This paper offers a partial outline of the conservative …

Leveraging Computer Vision-Based Hand Tracking In Smartphone Xr Exposure Scenarios To Enable Controller-Free Interaction, Alex C. Lim, Trang Nguyen

OneUSF Undergraduate Research Conference

Extended reality (XR) has emerged as an effective and convenient solution for broadening accessibility to exposure therapy. Smartphone-based XR, though cost-effective, is often constrained by limited interactivity, engendering a passive experience that can compromise the user-immersion and treatment efficacy. To address this limitation, this study presents a novel computer vision–based hand-tracking approach using Google MediaPipe, integrated within a stereoscopic smartphone-based XR system to enable real-time, controller-free interaction in a dog-fetch scenario. Hand landmark coordinates derived from MediaPipe are algorithmically adjusted based on changes in inter-knuckle distances during anterior/posterior movement to approximate depth, at which point interactive spheres are overlayed to …

Accelerating Protein Engineering: Using Computer Modeling To Identify Beneficial Interleukin-23 (Il-23) Mutations, Andrew S. Chadwell

OneUSF Undergraduate Research Conference

Interleukin-23 (IL-23) regulates inflammation, yet its overproduction, driven by genetics or overactive immune triggers, can lead to chronic inflammatory diseases like psoriasis. IL-23 consists of two subunits; an exclusive subunit, p19, and a second subunit, p40, that is shared with Interleukin-12. Driving selectivity of p19-p40 interactions promotes a shift in cytokine formation between IL-23 and IL-12. By integrating computational biology, protein engineering, and structural data from the RCSB Protein Data Bank (entry 4RGW), the research addressed structural challenges like unresolved regions in experimental structures and the difficulty of predicting beneficial mutations. Structural modeling using ColabFold, a prediction tool based on …

The Moderation Of Gender In The Relationship Between Social Cognition And Narrative Language Skills In Autistic Children, Zara Khan, Coral Morley

OneUSF Undergraduate Research Conference

Compared to males, autistic females often demonstrate a greater desire for social interactions and may imitate peers’ social behaviors, sometimes masking underlying social-cognitive difficulties (Hull et al., 2017; Lai et al., 2015). To better understand these differences, the present study focuses on two key components of social cognition (i.e., affect recognition and theory of mind (ToM)), and their associations with narrative listening comprehension. Gender may act as a moderator, showing variability between these variables; thereby providing a more nuanced view of autism that may inform assessment and screening practices rather than relying on the traditional male-centered research (Harrop et al., …

Bidirectional Associations Between Social-Cognitive Processes And Mathematics Achievement In Autistic Children, Carole M. Wadie, Conner Peltier, Quinn Slyker

OneUSF Undergraduate Research Conference

Mathematics achievement is a critical component of academic functioning, strongly predicting later educational and life outcomes (Kaskens et al., 2022; Tonizzi & Usai, 2024). Although prior research has examined mathematics achievement and general cognition, limited work has investigated the role of social-cognitive processes in mathematical development among autistic children. Skills such as theory of mind (ToM), affect recognition, and inferencing may support mathematical learning by enabling children to interpret instructions, integrate information, and apply conceptual understanding (Kloo et al., 2022; Kim et al., 2021). Developmental cascade theory suggests that functioning in one domain may influence development in another, with bidirectional …

Optimization Of Antibiotic Selection Conditions In Human T-Cell Lines To Study Mechanisms Of Resistance To Bi-Specific Antibody Therapy In Multiple Myeloma, Raphael Gabra

OneUSF Undergraduate Research Conference

Multiple myeloma is a malignancy of plasma cells for which emerging therapies increasingly target B-cell maturation antigen (BCMA). Many experimental approaches used to investigate therapeutic resistance rely on genetically modified cell populations that must be maintained through antibiotic selection to ensure stable expression of introduced constructs. However, antibiotic sensitivity varies across cell lines and drug types, and improper dosing can compromise experimental reproducibility by allowing unmodified cells to persist or inducing excessive cytotoxic stress. This study aimed to define efficient and practical selection conditions for two commonly used antibiotics, G418 and puromycin, in Jurkat and TALL-104 human T-cell lines. Cells …

Maternal Feedback Over Time: Associations With Youth Perceptions Of Autonomy Support, Andrew Middleton, Genevieve Martin, Alyssa Lazanowski, Wendy M. Rote

OneUSF Undergraduate Research Conference

Parental feedback and direction are often interpreted as controlling; however, developmental theory suggests these behaviors may function as autonomy support when they are responsive to youths’ need. Drawing on self-determination theory, autonomy supportive parenting involves the promotion of volitional functioning through behaviors that align with youths’ perspectives and fosters independent problem-making and a sense of choice (McCurdy et al., 2020; Zhang & Whitebread, 2021). Similarly, scaffolding frameworks emphasize that provisions of parental support (e.g., feedback, direction, and emotional encouragement) contingent on the child’s task performance can promote higher levels of independent functioning (Mermelshtine, 2017; Salonen et al., 2007). The present …

The Overestimation Of Minority Group Size, Kennedy Tennant, Kiara Overstreet, Ty Curci

OneUSF Undergraduate Research Conference

Politicians and citizens often claim that a problem is "growing" or even "out of control" without providing metrics to support their claim. We wondered if people who fear immigration might be prone to overestimate the percentage of people who they perceive as "foreign" and further, whether that overestimation is moderated by the degree of fear or contempt held towards that group. In Study 1, participants viewed fictitious graduate school applications and then estimated the percentage of applicants that were from the Middle East. In study 2, participants viewed fictitious head shots and estimated the percentage of individuals who were wearing …

Cyclobenzaprine: Psychiatric Side Effects In Patients With Mood Disorders, Shelby R. Mcgrew, Michael Pestova-Habera

OneUSF Undergraduate Research Conference

Cyclobenzaprine, also known under the brand name Flexeril, is one of the most widely prescribed skeletal muscle relaxants globally. While treatment is typically limited to post-injury pain relief, long-term use has increased due to evidence of pain reduction in patients with chronic conditions such as fibromyalgia and temporomandibular joint disorder. Recently, cyclobenzaprine was found to be contraindicated for patients with bipolar disorder and other mood disorders. This is thought to result from its structural similarity to amitriptyline, a tricyclic antidepressant. As a result, some patients utilizing cyclobenzaprine for pain management may experience acute manic episodes following administration. This study reviews …

Leveraging Cauti & Evidence-Based Best Practices, Jacob G. Slipak, Lauren Rae Selent, Lauren Reilly Mcconnell

OneUSF Undergraduate Research Conference

An estimated 44% of urinary tract infections are classified as catheter-associated urinary tract infections (CAUTIs). In 2020, stated United States CAUTI infection rates were estimated at 0.754 per 1000 catheter days1 (with higher rates in ICUs). CAUTI is associated with an adjusted incremental total hospital cost of $9,807 (p<0.0001) and increased length of stay of 3.01 days2 (p<0.0001). This study examines staff compliance with known CAUTI best practices. A quantitative, causal- comparative approach was utilized. All patients (n=119) had an indwelling foley catheter. The independent variables were the individual clinical units each patient was assigned to. The dependent variable was adherence to the CAUTI Prevention Bundle best practices. Best practices included proper removal protocol and catheter maintenance (ensuring an unobstructed flow). Initially, a MANOVA was used to compare differences across groups. For a statistically significant criteria one way ANOVA contrasts were conducted. There were statistically significant findings as evidenced by Wilk’s Λ (36, 472) = 0.53, p<0.0005. One-way ANOVA contrasts identified two statistically significant differences: 1) Less than half of employees (48%) were adhering to best practice guidelines for catheter removal protocol (p< 0.02); and 2) Employees (71%) were compliant with best practices for catheter care (p< 0.005). It was chilling to note that less than half of employees (48%) complied with the catheter removal process. This information is the first of its kind in CAUTI and may assist policymakers and other key stakeholders in Florida—and nationally—in identifying, designing and implementing strategies to promote best practices.
