Monitoring drought impacts in forest ecosystems is a complex process because forest ecosystems are composed of different species with heterogeneous structural compositions. Even though forest drought status is a key control on the carbon cycle, very few indices exist to monitor and predict forest drought stress. The Forest Drought Indicator (ForDRI) is a new monitoring tool developed by the National Drought Mitigation Center (NDMC) to identify forest drought stress. ForDRI integrates 12 types of data, including satellite, climate, evaporative demand, ground water, and soil moisture, into a single hybrid index to estimate tree stress. The model uses Principal Component Analysis …

A Genomic Analysis Of Osmotolerance In Staphylococcus Aureus, Dylan Casey, Roy D. Sleator

Department of Biological Sciences Publications

A key phenotypic characteristic of the Gram-positive bacterial pathogen, Staphylococcus aureus, is its ability to grow in low aw environments. A homology transfer based approach, using the well characterised osmotic stress response systems of Bacillus subtilis and Escherichia coli, was used to identify putative osmotolerance loci in Staphylococcus aureus ST772-MRSA-V. A total of 17 distinct putative hyper and hypo-osmotic stress response systems, comprising 78 genes, were identified. The ST772-MRSA-V genome exhibits significant degeneracy in terms of the osmotic stress response; with three copies of opuD, two copies each of nhaK and mrp/mnh, and five copies of opp. Furthermore, regulation of …


Are We Planning For Equity? Equity Goals And Recommendations In Local Comprehensive Plans, Carolyn G. Loh, Rose Kim Nov 2020

Are We Planning For Equity? Equity Goals And Recommendations In Local Comprehensive Plans, Carolyn G. Loh, Rose Kim

Urban Studies and Planning Faculty Research Publications

Problem, Research Strategy, and Findings:

Social equity goals are supposed to be prioritized in planning along with economic and environmental goals, yet in practice they are often de-emphasized. We develop a publicly available plan equity evaluation tool to investigate to what extent and in what ways local governments include goals and recommendations that would advance equitable outcomes in their comprehensive plans. Using plan content analysis, we find that most plans do not talk about equity, nor do they include many goals and recommendations that would advance equity. More recent plans, plans in communities with more planning capacity, plans in …

Health Sciences and Kinesiology Faculty Articles

Racial disparities in breast cancer are well-documented, and Black women assume a disproportionate burden of breast cancer mortality. Black women also commonly use hair products containing endocrine disrupting chemicals (EDCs) more often at an increased rate, as compared to other racial/ethnic groups. Emerging findings have reported the use of hair and other personal care products containing EDCs may contribute to breast cancer risk. While some sociocultural perspectives about hair and identity have been explored, the role of beauty expectations upheld by males has not been studied. Through a community-based participatory methodology, we explored perceptions and beliefs held by Black men …

Understanding how biodiversity responds to urbanization is challenging, due in part to the single-city focus of most urban ecological research. Here, we delineate continent-scale patterns in urban species assemblages by leveraging data from a multi-city camera trap survey and quantify how differences in greenspace availability and average housing density among 10 North American cities relate to the distribution of eight widespread North American mammals. To do so, we deployed camera traps at 569 sites across these ten cities between 18 June and 14 August. Most data came from 2017, though some cities contributed 2016 or 2018 data if it was …

Voltammetric Ph Measurements In Unadulterated Foodstuffs, Urine, And Serum With 3d-Printed Graphene/Poly(Lactic Acid) Electrodes, Fakher M. Rabboh, Glen D. O'Neil

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

The pH of a system is a critical descriptor of its chemistry—impacting reaction rates, solubility, chemical speciation, and homeostasis. As a result, pH is one of the most commonly measured parameters in food safety, clinical, and environmental laboratories. Glass pH probes are the gold standard for pH measurements but suffer drawbacks including frequent recalibration, wet storage of the glass membrane, difficulty in miniaturization, and interferences from alkali metals. In this work, we describe a voltammetric pH sensor that uses a three-dimensional (3D)-printed graphene/poly(lactic acid) filament electrode that is pretreated to introduce quinone functional groups to the graphene surface. After thoroughly …

Department of Pathology and Laboratory Medicine

Intracranial mesenchymal tumors with FET-CREB fusions are a recently described group of neoplasms in children and young adults characterized by fusion of a FET family gene (usually EWSR1, but rarely FUS) to a CREB family transcription factor (ATF1, CREB1, or CREM), and have been variously termed intracranial angiomatoid fibrous histiocytoma or intracranial myxoid mesenchymal tumor. The clinical outcomes, histologic features, and genomic landscape are not well defined. Here we studied twenty patients with intracranial mesenchymal tumors proven to harbor FET-CREB fusion by next-generation sequencing (NGS). The 16 female and 4 male patients had a median age of 14 years (range …

Faculty Research, Scholarly, and Creative Activity

Unoccupied Aerial Vehicles (UAVs), or drone technologies, with their high spatial resolution, temporal flexibility, and ability to repeat photogrammetry, afford a significant advancement in other remote sensing approaches for coastal mapping, habitat monitoring, and environmental management. However, geographical drone mapping and in situ fieldwork often come with a steep learning curve requiring a background in drone operations, Geographic Information Systems (GIS), remote sensing and related analytical techniques. Such a learning curve can be an obstacle for field implementation for researchers, community organizations and citizen scientists wishing to include introductory drone operations into their work. In this study, we develop a …

Design Of A Comprehensive Modeling, Characterization, Rupture Risk Assessment And Visualization Pipeline For Abdominal Aortic Aneurysms, Golnaz Jalalahmadi

Theses

Abdominal aortic aneurysms (AAA) is a dilation of the abdominal aorta, typically within the infra-renal segment of the vessel that cause an expansion of at least 1.5 times the normal vessel diameter. It is becoming a leading cause of death in the United States and around the world, and consequentially, in 2009, the Society for Vascular Surgery (SVS) practice guidelines expressed the critical need to further investigate the factors associated with the risk of AAA rupture, along with potential treatment methods. For decades, the maximum diameter (Dmax) was introduced as the main parameter used to assess AAA behavior and its …

A Markov Chain Approach For Forecasting Progression Of Opioid Addiction, Abhijit Gosavi, Susan L. Murray, N. Karagiannis

Engineering Management and Systems Engineering Faculty Research & Creative Works

The U.S. is currently facing an opioid crisis. Naltrexone is a common treatment for drug addiction; it reduces the desire to take opiates. However, addicts often stop treatment or continue to use opioids while in treatment. This results in increased fatalities and associated costs. A Markov-chain model is presented to analyze the progression of opioid addiction to assist the medical community in developing appropriate treatments. The model includes patients who continue opiate use while on naltrexone (blocked patients) and those who use opiates after missing naltrexone doses (unblocked patients). The other types of patients are abstinent (the best-case scenario) and …

The Role Of Hud In Alternative Splicing And Alternative Polyadenylation In The Brain, Rebecca M. Sena Nov 2020

The Role Of Hud In Alternative Splicing And Alternative Polyadenylation In The Brain, Rebecca M. Sena

Biomedical Sciences ETDs

RNA binding proteins (RBPs) regulate several processes in the cell, including alternative splicing and alternative polyadenylation. Hu proteins, a class of ELAV-like RBPs, are crucial for proper development and maintenance of the nervous system. Several Hu proteins, including HuD, have been shown to regulate alternative splicing and alternative polyadenylation of neuronal transcripts. However, previous studies have relied on molecular techniques to analyze individual transcripts, which do not provide a global overview of the transcriptome. The purpose of this study was to develop a bioinformatics pipeline to analyze splicing and polyadenylation using RNA-sequencing data. Once the pipeline was developed, it was …


Origins Of Amyloid Oligomers And Novel Approaches For Their Detection, Jeremy Barton Nov 2020

Origins Of Amyloid Oligomers And Novel Approaches For Their Detection, Jeremy Barton

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease, type II diabetes, and other amyloid diseases are known to be associated with the formation of amyloid aggregates. It has been thoroughly researched whether amyloid fibrils or oligomers are the main culprit for these diseases, and recent evidence has connected oligomers as the most disease relevant aggregate species. However, many difficulties have arose in confirming this hypothesis. Techniques for oligomer detection are often limited in their sensitivity, and in many cases are unable to distinguish oligomers from rigid fibrils. Additionally, the role oligomer splay in fibril assembly is still unclear, and has led to the belief that different …

Articles

In this paper a Vernier effect based sensor is analyzed and demonstrated experimentally in a tri-microfiber coupler (Tri-MFC) and polarization-maintaining fiber (PMF) loop interferometer (Tri-MFC-PMF) to provide ultrasensitive refractive index and temperature sensing. The main novelty of this work is an analysis of parameters of the proposed Tri-MFC-PMF with the objective of determining the conditions leading to a strong Vernier effect. It has been identified by simulation that the Vernier effect is a primary factor in the design of Tri-MFC-PMF loop sensing structure for sensitivity enhancement. It is furthermore demonstrated experimentally that enhancing the visibility of the Vernier spectrum in …
