Knowledge Building Through Interdisciplinary Units, Jessica A. Deboer

Masters Projects

Research demonstrates that developing a strong knowledge base is vitally important for students to demonstrate comprehension in reading. Comprehension strategies are an important skill to learn, but can only be utilized if a student has background knowledge of the subject. Schema theory supports the idea that knowledge is most effectively acquired through networks of prior knowledge built into the brain’s long term memory. The more vocabulary and concept knowledge a person has in their network of schemata the easier it is for them to connect and hold onto new information. An interdisciplinary curriculum can grow students' knowledge and their comprehension …

Investigating Cloth Sculpting For Simulation Control In Virtual Reality, Matthew S. Bishop

Theses and Dissertations

Artists require control and predictability over physically based simulations to create their required animation. This control can lead to reduced iteration time to get the desired simulation results. Controlling cloth simulations can require manual effort to create goal keyframes for control algorithms to match. Current techniques and research utilize a keyboard and mouse to create these goal keyframes. Other research has looked at using a virtual reality (VR) head-mounted display with controllers to improve the experience of completing similar animation tasks. However, we are not aware of any research that attempts to use VR as a tool to assist artists …

Pathophysiology In Brain Arteriovenous Malformations: Focus On Endothelial Dysfunctions And Endothelial-To-Mesenchymal Transition, Jae Yeong Jeong, Adrian E Bafor, Bridger H Freeman, Peng R Chen, Eun S Park, Eunhee Kim

Faculty, Staff and Student Publications

Brain arteriovenous malformations (bAVMs) substantially increase the risk for intracerebral hemorrhage (ICH), which is associated with significant morbidity and mortality. However, the treatment options for bAVMs are severely limited, primarily relying on invasive methods that carry their own risks for intraoperative hemorrhage or even death. Currently, there are no pharmaceutical agents shown to treat this condition, primarily due to a poor understanding of bAVM pathophysiology. For the last decade, bAVM research has made significant advances, including the identification of novel genetic mutations and relevant signaling in bAVM development. However, bAVM pathophysiology is still largely unclear. Further investigation is required to …

Genomic, Morphological And Physiological Data Support Fast Ecotypic Differentiation And Incipient Speciation In An Alpine Diving Beetle, Susana Pallares, Joaquin Ortego, Jose Antonio Carbonell, Eduardo Franco-Fuentes, David T. Bilton, Andres Millan, Pedro Abellan

School of Biological and Marine Sciences

An intricate interplay between evolutionary and demographic processes has frequently resulted in complex patterns of genetic and phenotypic diversity in alpine lineages, posing serious challenges to species delimitation and biodiversity conservation planning. Here we integrate genomic data, geometric morphometric analyses and thermal tolerance experiments to explore the role of Pleistocene climatic changes and adaptation to alpine environments on patterns of genomic and phenotypic variation in diving beetles from the taxonomically complex Agabus bipustulatus species group. Genetic structure and phylogenomic analyses revealed the presence of three geographically cohesive lineages, two representing trans-Palearctic and Iberian populations of the elevation-generalist A. bipustulatus and …

Discovering And Characterizing Conserved Anthelmintic Targets In The Early Parasitic Stages Of Gastrointestinal Nematodes, Hyeim Jung

Arts & Sciences Graduate Student Theses and Dissertations

Gastrointestinal nematodes (GINs) collectively infect 1.5 billion people, leading to mortality and various forms of morbidity in humans and hindering normal development in children. GINs also diminish the productivity of food animals, which are crucial for economic and nutritional well-being, particularly in developing countries. Currently, the world still primarily relies on only a few drug classes for global de-worming of GINs in humans and animals. However, the high rate of reinfection, disappointing treatment success rates, and increasing drug resistance make GINs one of the most important contributors to promoting and maintaining global poverty. This highlights the urgent need for more …

Modern Building Structures Are A Landscape-Level Driver Of Bat–Human Exposure Risk In Kenya, Tamika Lunn, Reilly T. Jackson, Paul W. Webala, Joseph G. Ogola, Kristian M. Forbes

Biological Sciences Faculty Publications and Presentations

Identifying the locations and drivers of high-risk interfaces between humans and wildlife is crucial for managing zoonotic disease risk. We suggest that continent-wide improvements to residential housing in Africa are inadvertently creating artificial roosting habitat for synanthropic free-tailed bats (family Molossidae), and that improved buildings are a rapidly accelerating exposure interface that needs urgent research attention and investment. Along a residential gradient in rural southern Kenya, we mapped building use by free-tailed bats in 1109 buildings. We show that bats often roost in human-occupied buildings, with almost one-in-ten buildings exhibiting evidence of bat occupation (9.2%) and one-in-13 found to contain …

Bispecific Antibodies And Autologous Chimeric Antigen Receptor T Cell Therapies For Treatment Of Hematological Malignancies, Samer Al Hadidi, Helen E Heslop, Malcolm K Brenner, Masataka Suzuki

Faculty, Staff and Students Publications

In recent years, the therapeutic landscape for hematological malignancies has markedly advanced, particularly since the inaugural approval of autologous chimeric antigen receptor T cell (CAR-T) therapy in 2017 for relapsed/refractory acute lymphoblastic leukemia (ALL). Autologous CAR-T therapy involves the genetic modification of a patient's T cells to specifically identify and attack cancer cells, while bispecific antibodies (BsAbs) function by binding to both cancer cells and immune cells simultaneously, thereby triggering an immune response against the tumor. The subsequent approval of various CAR-T therapies and BsAbs have revolutionized the treatment of multiple hematological malignancies, highlighting high response rates and a subset …

Large Language Models Have Divergent Effects On Self-Perceptions Of Mind And The Attributes Considered Uniquely Human, Oliver L. Jacobs, Farid Pazhoohi, Alan Kingstone

School of Psychology

The rise of powerful Large Language Models (LLMs) provides a compelling opportunity to investigate the consequences of anthropomorphism, particularly regarding how their exposure may influence the way individuals view themselves (self-perception) and other people (other-perception). Using a mind perception framework, we examined attributions of agency (the ability to do) and experience (the ability to feel). Participants evaluated their agentic and experiential capabilities and the extent to which these features are uniquely human before and after exposure to LLM responses. Post-exposure, participants increased evaluations of their agentic and experiential qualities while decreasing their perception that agency and experience are considered to …

The Neonatal Fc Receptor (Fcrn) Is A Pan-Arterivirus Receptor, Teressa M Shaw, Meagan E Sullender, Megan T Baldridge, Et Al.

2020-Current year OA Pubs

Arteriviruses infect a variety of mammalian hosts, but the receptors used by these viruses to enter cells are poorly understood. We identified the neonatal Fc receptor (FcRn) as an important pro-viral host factor via comparative genome-wide CRISPR-knockout screens with multiple arteriviruses. Using a panel of cell lines and divergent arteriviruses, we demonstrate that FcRn is required for the entry step of arterivirus infection and serves as a molecular barrier to arterivirus cross-species infection. We also show that FcRn synergizes with another known arterivirus entry factor, CD163, to mediate arterivirus entry. Overexpression of FcRn and CD163 sensitizes non-permissive cells to infection …

Distinct Regulation Of Atm Signaling By Dna Single-Strand Breaks And Ape1, Haichao Zhao, Jia Li, Zhongsheng You, Howard D Lindsay, Shan Yan

2020-Current year OA Pubs

In response to DNA double-strand breaks or oxidative stress, ATM-dependent DNA damage response (DDR) is activated to maintain genome integrity. However, it remains elusive whether and how DNA single-strand breaks (SSBs) activate ATM. Here, we provide direct evidence in Xenopus egg extracts that ATM-mediated DDR is activated by a defined SSB structure. Our mechanistic studies reveal that APE1 promotes the SSB-induced ATM DDR through APE1 exonuclease activity and ATM recruitment to SSB sites. APE1 protein can form oligomers to activate the ATM DDR in Xenopus egg extracts in the absence of DNA and can directly stimulate ATM kinase activity in …

Global Portraits From A Changing Climate: The Influence Of Environmental Storytelling On The Climate Narrative, Alexandra Welch

Capstone Collection

Environmental Storytelling can influence the climate narrative and serve as a catalyst to structurally alter how individuals think about the environment. The medium of the “Eco-film” allows viewers to create intimate connections with the natural world, and in turn alter how individuals engage and perceive issues like climate change. To combat climate denialism this project showcases different hopeful stories in a deliverable video collection, called “Global Portraits from a Changing Climate”. Two of these videos will be filmed in Germany, featuring the Waldrapp Team Research and Conservation project. One of the videos from Waldrapp Team will touch on the social …

Living Dead Forests: Assessing Detrital Services In Puget Sound Pseudotsuga Menziesii Ecosystems, Forrest Becker

Capstone Collection

Coarse woody debris (CWD), the detrital result of down wood recruitment, contributes to wildlife habitat, nutrient cycling, morphological processes like soil formation, and each forest’s sense of place but if undermanaged can fuel wildfires or obstruct stakeholder use. Despite its ubiquity in Puget Sound Douglas fir (Pseudotsuga menziesii) forests in Washington, USA, few studies quantify the exact ecosystem services which down wood provides. This study seeks to understand how forest managers can estimate the ecosystem services of down wood and how human communities perceive down wood management between community, public, and private Douglas fir (P. menziesii) …

Given this …

"You Are More Than Just Your Gift:" Facework And Idealization In Disney's Encanto, Janelle L.H. Gruber, Valerie Lynn Schrader

Communication and Theater Association of Minnesota Journal

In this rhetorical analysis, we apply Goffman’s theory of facework to the Disney film Encanto, arguing that Encanto provides important lessons regarding facework and advocates for using facework in moderation. Encanto tells the story of the Madrigals, a family who experiences a miracle that results in each member of the family having a special gift – all except for one, the teenage protagonist, Mirabel. When Mirabel recognizes that both the miracle and her family are in danger, she realizes that her individual family members are using facework in order to fit in with the rest of the family and impress …

Development Of A Methodology For Optimizing Satellite Durability By Coupling Advanced Orbit Propagation With High Fidelity 3d Thermal-Electrical Simulation, Corey D. Packard, Logan R. Canull, Zachary J. Edel, Timofey Golubev, Michael L. Larsen, Nate Mccoun

Small Satellite Conference

In the rapidly evolving landscape of low Earth orbit (LEO) satellite technology, this study presents a pioneering approach for analyzing satellite durability through advanced orbit propagation and high fidelity 3D thermal-electric simulation. Small satellites, packed with high power components and rapidly transitioning between sunlit and eclipsed orbit segments, often feature limited thermal control systems that make thermal management a challenging (but critical) task. Additionally, the durability of battery cells and photovoltaic (PV) panels over the mission lifetime of small satellites is an important concern. Cycling and calendar fade take their toll on battery lifetime, and PV degradation reduces operational efficiency …

Charlotte: A Modern Tool For Cave Surveying, Luca Tringali Mr., Giacomo Canciani Dr., Alexander Debenjak, Tecla Tripari

International Journal of Speleology

The future of cave surveying is a full 3D scan, as automatic as possible, capturing all morphologically relevant details. However, the vast majority of cavers are still using tools designed more than 15 years ago. The advancements in tools for architects, CAD designers, programmers of VR and robotics could be helpful also for the caving community. That’s why Charlotte, a cheap DIY 2.5D scanner designed for cave surveying, was developed and built. To demonstrate its capabilities, a new survey of Grotta Regina del Carso cave (cad. nr. 2328/4760VG), the biggest cave in the Gorizia Karst, has been realized and published. …

Maximizing Legged Accelerations: A Matter Of Force, Time, And Gravity, Lance Brooks

Applied Physiology and Wellness Theses and Dissertations

Sprint running accelerations require runners to apply surface forces that: support body weight by pushing downward, accelerate the body horizontally by pushing backward, and align the direction of the push with the body’s mass center to maintain balance and posture, which imposes an upper limit on the average forward acceleration force equal to the average gravitational force (1.0 G) acting on the runner. This expectation arises from the mechanical constraints imposed by the need to generate sufficient vertical force to support body weight against gravity while simultaneously producing horizontal force to accelerate forward and aligning the push through the center …

Immunological Feedback Loops Generate Parasite Persistence Thresholds That Explain Variation In Infection Duration, Clayton E. Cressler, Daniel C.G. Metz, David A. Chang Van Oordt, Andrea L. Graham

School of Biological Sciences: Faculty Publications

Infection duration affects individual host fitness and between-host transmission. Whether an infection is cleared or becomes chronic depends on the complex interaction between host immune responses and parasite growth. Empirical and theoretical studies have suggested that there are critical thresholds of parasite dose that can determine clearance versus chronicity, driven by the ability of the parasite to manipulate host immunity. However, the mammalian immune response is characterized by strong positive and negative feedback loops that could generate duration thresholds even in the absence of direct immunomodulation. Here, we derive and analyse a simple model for the interaction between T-cell subpopulations …

Clinical Research Faculty Publications

Although fasting is increasingly applied for disease prevention and treatment, consensus on terminology is lacking. Using Delphi methodology, an international, multidisciplinary panel of researchers and clinicians standardized definitions of various fasting approaches in humans. Five online surveys and a live online conference were conducted with 38 experts, 25 of whom completed all 5 surveys. Consensus was achieved for the following terms: “fasting” (voluntary abstinence from some or all foods or foods and beverages), “modified fasting” (restriction of energy intake to max. 25% of energy needs), “fluid-only fasting,” “alternate-day fasting,” “short-term fasting” (lasting 2–3 days), “prolonged fasting” (≥4 consecutive days), and …

Bio-Enriched Soil Technologies (Best), Norma Arcelia Alcantar

USF Patents

A bio-enriched soil and method of production is presented. If water supply is scant, bio-enriched soil technologies (BEST) are able to attract, store, and transport water and nutrient molecules to a plant in a controlled way. If the water or nutrient resources are excessive, BEST can release the excess and supply only what is needed. Hence, bio-enriched soil can function in climates in which crops normally are under stress by increasing the bioavailability of nutrients and water.

Spring-Loaded Device For Eliciting Deep Tendon Reflexes, Kevin Chao Hong

USF Patents

A deep tendon reflex-eliciting device actuated by pressure against a patient's skin, which releases a spring-loaded mass that delivers an impulse through a fully-enclosed housing. This device includes a weight contained within the casings, and a mainspring in communication with the weight. The mainspring has a bias toward expansion. In the compressed position, the mainspring is also compressed, and the weight is pushed backwards into the rear casing. The weight is released to be driven forward by the mainspring. The weight strikes the inside of the forward casing, delivering an impulse to a surface against which the device is pressed. …

Predictive And Prescriptive Analytics For Minimizing The Cost Of Recidivism, Adreana Julander

Operations Research and Engineering Management Theses and Dissertations

A problem faced by the United States is the ever increasing prison population. There are inmates serving long sentences, new inmates being sentenced for the first time, and those who have previously served prison sentences that reoffend. The third group and the reduction of recidivism are the focus this dissertation. It is estimated that over 80% of inmates released from prison will reoffend within the next ten years. Is there an optimal sentence length that reduces that chance of an ex-convict reoffending? Are there programs or opportunities that some inmates have while incarcerated that reduce the probability they will return …

Comparing Cadaveric And 3d-Printed Laryngeal Models In Transcutaneous Injection Laryngoplasty, Megha Chandna, Sana Siddiqui, Dylan Bertoni, Marah Sakkal, Sara Belko, Maurits Boon, Joseph Spiegel

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

BACKGROUND: There is increasing focus on the development of high-quality simulation models for medical education. Cadaveric models, although considered more realistic, may be difficult to obtain and costly. The advent of three-dimensional (3D) printing has offered a low-cost, reliable, and reproducible alternative. This study sought to compare the utility of 3D-printed to cadaveric models for training in transcutaneous injection laryngoplasty (TIL).

METHODS: A simulation course with a cross-over design was employed. Video laryngoscopes were utilized for both the 3D and cadaveric models to assess the accuracy of injection into the vocal fold. Pre-procedure and post-procedure surveys were administered to evaluate …

Madelung Mechanics And Superoscillations, Mordecai Waegell

Mathematics, Physics, and Computer Science Faculty Articles and Research

In single-particle Madelung mechanics, the single-particle quantum state Ψ(⃗x, t) = R(⃗x, t)eiS(⃗x,t)/h is interpreted as comprising an entire conserved fluid of classical point particles, with local density R(⃗x, t)2 and local momentum ⃗∇S(⃗x, t) (where R and S are real). The Schrödinger equation gives rise to the continuity equation for the fluid, and the Hamilton–Jacobi equation for particles of the fluid, which includes an additional density-dependent quantum potential energy term Q(⃗x, t) = − ¯h2 2m ⃗∇R(⃗x,t) R(⃗x,t) , which is all that makes the fluid behavior nonclassical. In particular, the quantum potential can become negative and create a …

Stanniocalcin 2 Governs Cancer Cell Adaptation To Nutrient Insufficiency Through Alleviation Of Oxidative Stress, Shuo Qie, Haijuan Xiong, Yaqi Liu, Chenhui Yan, Yalei Wang, Lifeng Tian, Chenguang Wang, Nianli Sang

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Solid tumours often endure nutrient insufficiency during progression. How tumour cells adapt to temporal and spatial nutrient insufficiency remains unclear. We previously identified STC2 as one of the most upregulated genes in cells exposed to nutrient insufficiency by transcriptome screening, indicating the potential of STC2 in cellular adaptation to nutrient insufficiency. However, the molecular mechanisms underlying STC2 induction by nutrient insufficiency and subsequent adaptation remain elusive. Here, we report that STC2 protein is dramatically increased and secreted into the culture media by Gln-/Glc- deprivation. STC2 promoter contains cis-elements that are activated by ATF4 and p65/RelA, two transcription factors activated by …
