3d Organ-Scale Models Of Tumor Growth And Treatment, Rafael Ramon Bravo

USF Tampa Graduate Theses and Dissertations

To understand the dynamics of cancer, mathematical oncologists have developed models of tumor growth and treatment response. Some models are mechanistic and approach tumor growth at the cell-scale, focusing on the evolution of cancerous cells within the ecology of normal tissue, and are often simulated with agent-based modeling. Other models are more clinically motivated and model tumor growth operating at the organ-scale, using patient data to predict treatment response, and are often simulated with partial differential equations. We developed the Hybrid Automata Library which includes both agent-based modeling and partial differential equations for modeling at either of these scales. We …

Comparison Of Contingent Vocal Imitation With And Without Supplemental Reinforcement On Vocalizations Of Children With Asd, Megan L. Baumgartner

USF Tampa Graduate Theses and Dissertations

Verbal communication often entails vocal verbal behavior. Research has shown that many children with autism spectrum disorder (ASD) experience delays in the onset of vocalizations, which can hinder the acquisition of more complex vocal verbal behavior. Findings of previous research have also shown that early intensive behavioral intervention (EIBI) is effective at teaching various skills, including verbal behavior, to children with ASD. Moreover, several studies have shown that contingent imitation leads to increases in the frequency of vocalizations and echoic responding of children with ASD; however, no study to date has compared the effectiveness of contingent vocal imitation (CVI) with …

Physiological And Circadian Outcomes Of Fkbp5 Imbalance: Insights From Two Models, Niat Tsegai Gebru

Declined memory is a hallmark of Alzheimer’s disease (AD). Experiments in rodents and human postmortem studies suggest that serotonin (5-hydroxytryptamine, 5-HT) plays a role in memory, but the underlying mechanisms are unknown. Here, we investigate the role of 5-HT 2C receptor (5-HT2CR) in regulating memory. Transgenic mice expressing a humanized HTR2C mutation exhibit impaired plasticity of hippocampal ventral CA1 (vCA1) neurons and reduced memory. Further, 5-HT neurons project to and synapse onto vCA1 neurons. Disruption of 5-HT synthesis in vCA1-projecting neurons or deletion of 5-HT2CRs in the vCA1 impairs neural plasticity and memory. We show that a selective 5-HT2CR agonist, …

Monitoring Water Meniscus Formation At Nanocontacts With Shear-Force Acousto Near-Field Microscopy, Xiaohua Wang, Rodolfo Fernandez, Theodore Brockman, Kacharat Supichayanggoon, Andres H. La Rosa

Physics Faculty Publications and Presentations

Shear-force acoustic near-field microscopy (SANM) is employed to monitor stochastic formation and post dynamic response of a water meniscus that bridges a tapered gold probe (undergoing lateral oscillations of a few nanometers amplitude at constant frequency) and a flat (gold or silicon oxide) substrate. As the probe further approaches the substrate, its amplitude decreases. Shear forces (of yet unknown precise origin) are typically invoked to explain the apparently pure damping effects affecting the probe's motion. Herein, SANM measurements underscore instead the role of near-field acoustic emission from the water meniscus as an elastic energy dissipation channel involved in shear interactions. …
