Real-Time Arrhythmia Detection Using Convolutional Neural Networks, Thong Vu, Tyler Petty, Kemal Yakut, Muhammad Usman, Wei Xue, Francis M. Haas, Robert A. Hirsh, Xinghui Zhao

Henry M. Rowan College of Engineering Departmental Research

Cardiovascular diseases, such as heart attack and congestive heart failure, are the leading cause of death both in the United States and worldwide. The current medical practice for diagnosing cardiovascular diseases is not suitable for long-term, out-of-hospital use. A key to long-term monitoring is the ability to detect abnormal cardiac rhythms, i.e., arrhythmia, in real-time. Most existing studies only focus on the accuracy of arrhythmia classification, instead of runtime performance of the workflow. In this paper, we present our work on supporting real-time arrhythmic detection using convolutional neural networks, which take images of electrocardiogram (ECG) segments as input, and classify …

The Influence Of Grazing Systems On Bird Species Richness And Density In The Nebraska Sandhills, Silka L.F. Kempema, Walter H. Schacht, Larkin A. Powell

School of Natural Resources: Faculty Publications

Grazing is the de facto method of habitat management used in much of the Nebraska Sandhills. Ranchers use a variety of grazing systems, and our goal was to evaluate the effects of systems on grassland birds. We estimated the species richness and density of grassland birds for three grazing systems used on private ranches: long, medium, and short duration grazing systems. We observed sixty species, and the grazing system with pastures utilizing long duration grazing periods had the highest estimates of species richness as well as the most heterogeneous habitat structure. Differences in species richness among systems were most pronounced …

"Operation Motivation" - Samuel Shepard Jr., Nicalee Stephens-Wilson

Dissertations

African-American students have often faced systemic oppression and racial inequities as learners in the United States. Public schools in their communities lacked the resources to offer full access to a fair and equitable education. For years, human rights activists fought for radical changes in public schools. Finally, in 1954, the U. S. Supreme Court in Brown v. Board of Education ruled segregation in public schools unconstitutional. The Brown decision did not have the power to eliminate the long-established segregation practices. Nor did it grant access to educational equity for children of color. Dr. Samuel Shepard Jr. began his work in …

New Methods For Stereoselective Glycosylation In Application To Significant Biomedical Targets, Melanie L. Shadrick

Dissertations

Glycosyl halides have been utilized for glycosylation reactions since the early studies by Arthur Michael, nearing the end of the 19^th century. Koenigs and Knorr then utilized silver salts to activate glycosyl bromides and chlorides to create synthetic glycosides. Many efforts to improve the outcome of reactions with glycosyl halides have emerged. The key emphasis has traditionally been placed on reaction rates, product yields, and stereocontrol. Recently, our lab reported that silver(I) oxide-mediated Koenigs-Knorr glycosylation reaction can be dramatically accelerated in the presence of catalytic acid additives. Methods to improve glycosylation was explored using mannosyl and glucosyl bromides. However, …

The Contributions Of Mental Health Issues, Traumatic Brain Injury, And Adverse Childhood Experiences To Recidivism Among Rural Jail Incarcerees, Lauren N. Miley

USF Tampa Graduate Theses and Dissertations

Recidivism should be a major concern, particularly for American jails. The Unites States incarcerates 2.3 million people, a number exceeding rates in any other country. Approximately 90% of those individuals will reenter society at some point, and roughly half of those people will ultimately return to jail. This revolving door costs U.S. taxpayers upwards of $39 billion per year, and undermines public safety. Therefore, breaking this cycle of incarceration and recidivism is of utmost concern, and the focus of this dissertation. Mental health problems, traumatic brain injury (TBI), and adverse childhood experiences (ACEs) are three potential risk factors for recidivism …

Enhanced Luminescence Efficiency In Eu-Doped Gan Superlattice Structures Revealed By Terahertz Emission Spectroscopy, Fumikazu Murakami, Atsushi Takeo, Brandon Mitchell, Volkmar Dierolf, Yasufumi Fujiwara, Masayoshi Tonouchi

Physics & Engineering Faculty Publications

Eu-doped Gallium nitride (GaN) is a promising candidate for GaN-based red light-emitting diodes, which are needed for future micro-display technologies. Introducing a superlattice structure comprised of alternating undoped and Eu-doped GaN layers has been observed to lead to an order-of-magnitude increase in output power; however, the underlying mechanism remains unknown. Here, we explore the optical and electrical properties of these superlattice structures utilizing terahertz emission spectroscopy. We find that ~0.1% Eu doping reduces the bandgap of GaN by ~40 meV and increases the index of refraction by ~20%, which would result in potential barriers and carrier confinement within a superlattice …

Mechanisms, Evolution, And Rapid Diagnosis Of Carbapenem Resistance, Taalin Shale Hoj

Theses and Dissertations

An estimated 70% of bacterial infections in the United States are resistant to first-line antibiotics. Of these, among the most difficult to treat are highly resistant to carbapenems, an antibiotic class used as a last resort. Septicemia, particularly when caused by a carbapenem-resistant organism, is among the most challenging clinical scenarios to treat, with an overall mortality rate of carbapenem-resistant septicemias 63.8%. Encouragingly, if effective antimicrobial treatment begins within 1-3 hours of septic shock onset, patient survival rates are around 80%. The first section of this work describes a real-time PCR-based assay that when coupled with existing bacteria-blood separation technology, …

Elucidating The Architecture Of The Tclijn Complex That Converts Cysteine To Thiazoles In The Biosynthesis Of Micrococcin, Diana G. Calvopina Chavez

Theses and Dissertations

Thiopeptides are a family of antimicrobial peptides that are characterized for having sulfur-containing heterocycles, and for being highly post-translationally modified. Numerous thiopeptides have been identified; almost all of which inhibit protein synthesis in gram-positive bacteria. These intrinsic antimicrobial properties make thiopeptides promising candidates for the development of new antibiotics. The antimicrobial peptide micrococcin is a thiopeptide that is synthesized by the ribosome and undergoes several post-translational modifications (PTMs). Micrococcin is formed from a precursor peptide, TclE. TclE comprises an N-terminal leader (35-AA) that is crucial for recognition of the PTM machinery, alongside a C-terminal core sequence (14-AA) that undergoes multiple …
