Scrollar Invariants of Tropical Chains of Loops

We define scrollar invariants of tropical curves with a fixed divisor of rank 1. We examine the behavior of scrollar invariants under specialization, and compute these invariants for a much-studied family of tropical curves. Our examples highlight many parallels between the classical and tropical theories, but also point to some substantive distinctions.

COMPARING, CONTRASTING, AND EVALUATING SINGLE CASE RESEARCH DESIGNS AND DESCRIBING HOW TO APPLY COACHING TECHNIQUES IN AN APPLIED SETTING

Kasey Waddell
During the Spring 2020 semester, students within the applied behavior analysis/special education/interdisciplinary early childhood education program were conducting applied thesis projects within typical contexts as part of their fulfillment of the requirements of a master’s degree program. Due to the coronavirus disease 2019 (COVID-19), public schools and related facilities closed with no plans to reopen within the time frame to allow for graduation for students in the last semester of their graduate program. Students were...

AN EXAMINATION OF SEXUAL FANTASY AND INFIDELITY

Katherine Haus
Infidelity is a common behavior, influencing many people within romantic relationships (Mark & Haus, 2019). Many factors have been linked to increased infidelity engagement, but no studies exist documenting the role of sexual fantasy regarding infidelity. One such predictor of infidelity is need fulfillment, or the extent to which one’s needs are fulfilled in their relationship (Le & Agnew, 2001). Sexual fantasy is a highly common, but largely understudied sexual behavior (Lehmiller, 2018). Therefore, the...

Compositional Modeling

Students of composition develop two skills simultaneously: craft and creativity. Since students are more naturally inclined to focus on one of these skills over the other, finding the proper balance is an educational challenge. An effective pedagogical system for composition cultivates both of these necessary skills. Imitation was a preferred pedagogical approach during the Classical period. In his 1848 book School of Practical Composition, Carl Czerny instructs his readers to apply the extensive rules of...

CLINICAL AND NEUROPHYSIOLOGICAL EFFECTS OF DRY NEEDLING ON INDIVIDUALS WITH CHRONIC ANKLE INSTABILITY

Jennifer Mullins
Ankle sprains are generally considered innocuous injuries; however, as many as 74% of patients will develop chronic symptoms. 1-3 Chronic ankle instability (CAI) is defined by a history of ankle sprain accompanied by ongoing bouts of giving way, residual ankle sprain symptoms, and a decrease in patient-perceived function. As understanding of sensorimotor deficits in individuals with CAI have advanced, treatment strategies have evolved to include a robust focus on balance training to mitigate dynamic and...

Prostate Cancer Resistance to Cabazitaxel Chemotherapy

Diane Begemann
The plasticity of prostate tumors contributes to the heterogeneity in response and acquisition of therapeutic resistance in advanced prostate cancer. Disruption of the phenotypic landscape via epithelial-mesenchymal transition (EMT) enables prostate tumors to invade and metastasize. Our previous studies demonstrated that cabazitaxel (a 2nd generation FDA-approved taxane chemotherapy) that is used for treatment of castration-resistant prostate cancer (CRPC), causes reversal of EMT to mesenchymal-epithelial transition (MET). The present study examined the effect of sequencing cabazitaxel...

ANALYSTS’ EPS FORECAST REVISIONS AFTER REPURCHASE ANNOUNCEMENTS

Meng Huang
Analysts’ earnings per share (EPS) forecasts are one of the most widely used indicators of firm performance by market participants and firm executives. There are two components in EPS forecasts, but prior literature almost invariably focuses on the net income component (numerator) and ignores the shares outstanding component (denominator). Changes in shares outstanding mechanically alter EPS forecasts due to a changed denominator. These mechanical changes in EPS forecasts, however, do not reflect a firm’s real...

SOIL BULK DENSITY EFFECTS ON RUNOFF ESTIMATION

Colton Pugh
Urbanization has long been a major factor in the hydrology of surrounding areas. Engineers are commonly tasked with mitigating the extra runoff that urbanization brings with it. The NRCS Curve Number (CN) method is a commonly-used approach to predicting the amount of runoff that will be experienced from a given area. However, this method is known to be highly simplified in model of the processes involved. This study focused on determining the relationships between soil...

SAFETY CONCEPTS FOR EVERY RIDE

Shannon Wood
Rotational falls are the leading cause of death and serious injury in the equestrian sport of eventing. Previous studies to develop safety devices used physical models representing one or at most several physical situations leading to different designs and no common understanding. In this thesis, a statistical ensemble model is developed and applied to generate and evaluate 10,000 different situations that might potentially lead to rotational falls. For accurate statistical representation of the horse and...

Street Affects

Laçin Tutalar
This paper argues that affective moments between street musicians and the audience in Istanbul, Turkey suggest a loose connection to open and highly affective practices of hearing. The street brings them together during the moments of performance. The performance twists the power of sound that the musician makes and draws that into visualization of the moment, which underlines a peculiar affective attachment on the audience's side. The city's, musician's, and the listening practices' significance in...

EXPANDED PREDICTIVE EQUATION FOR DC ARC-FLASH INCIDENT ENERGY IN 125V BATTERY SYSTEMS

Austin Gaunce
Arc-flash is a dangerous phenomenon that can occur during an arcing fault in an electrical system. People nearby may be subjected to extreme heat, light, pressure, and sound. Research regarding arc-flash has focused primarily on AC arc-flash due to the prevalence of AC electricity in the grid. However, the grid has begun to integrate more DC electrical sources as a result of decentralization efforts and environmental concerns. The increased proliferation of DC electrical sources demands...

Full-Depth Reclamation of Asphaltic Concrete Pavements

Tony L. Beckham, Brad W. Rister & Charlie Sun
The Kentucky Transportation Cabinet (KYTC) has used a full-depth reclamation (FDR) process over the past few years to rehabilitate asphalt pavements exhibiting widespread base failures. FDR transforms existing hot-mix asphalt (HMA) pavement and underlying granular materials into a stabilized base layer. The stabilized layer is then overlaid with a new pavement surface layer. Until now, deciding when and how to use the FDR process has not been well specified in Kentucky — the Cabinet has...

Can Less Be More?

Xian Wu
The present study addressed a core research question of “Can less be more?” concerning study load, which has become increasingly worrisome and controversial around the world. This idea reflects the philosophy of pursuing efficiency and effectiveness on learning, namely that a lighter study load may result in more successful academic achievement. The study adopted the IPO (input-process-output) model to address five interrelated research questions: 1) What are the structural characteristics of study load? 2) Is...

A FRAMEWORK FOR HETEROLOGOUS BIOSYNTHESIS OF NATURAL PRODUCTS IN MAMMALIAN CELLS VIA POLYMER-MEDIATED TRANSFECTIONS

Logan Warriner
With the promise to treat a multi-faceted list of serious inherited and acquired diseases, such as cancer, neurodegenerative and infectious diseases, and inherited genetic indications, gene therapy has continued to push the boundaries of traditional medicine since its earliest implementation. While much progress has been made, clinical success has largely remained elusive. Immunogenicity, difficulty producing commercially relevant quantities, and having a limited genetic payload still limits the ability of viruses to act as directed delivery...

Rachel Catchings, Steven Waddle, Hala Nassereddine, Gabriel B. Dadi, Makram Bou Hatoum & Walter Johnson
Since 2009, Kentucky has made its 3D design data available as a supplemental reference to bidders through the project delivery process. This research discusses methods for ensuring electronic engineering data (EED) — and specifically the proposed digital terrain model (DTM) — support modern construction management methods at the Kentucky Transportation Cabinet (KYTC). Researchers performed a literature review, surveyed KYTC construction and design staff, engaged with Cabinet staff and industry members to understand the current state...

EL BILDUNGSROMAN FEMENINO MExICANO

Yorki Encalada Egúsquiza
The late 20th and early 21st centuries have not only favored a steady growth in Chicana literary production but have also revealed an alternative identity of the Mexican American border woman, the meXicana. Rosa Linda Fregoso, in MeXicana Encounters (2003), coins and defines this term as “the interface between Mexicana and Chicana,” and employs it to examine the experiences and representations of Mexicanas and Chicanas without eliminating the differences between them. This study borrows this...

Development of Universal Solver for High Enthalpy Flows Through Ablative Materials

Umran Duzel
Atmospheric entry occurs at very high speeds which produces high temperature around the vehicle. Entry vehicles are thus equipped with Thermal Protection Systems which are usually made of ablative materials. This dissertation presents a new solver that models the atmospheric entry environment and the thermal protection systems. In this approach, both the external flow and the porous heat shield are solved using the same computational domain. The new solver uses the Volume Averaged Navier-Stokes Equations...

Deconvolution Tools for Extracting Insight from Challenging Two-Flavin Systems

Dallas Bell
Flavoproteins have long been explored for their ubiquity among a number of metabolic and energetic reactions. The flavin cofactor has the inherent benefit of distinct spectral changes associated with redox transitions; however, the double-edged sword is incurred as these distinct signatures overlap and take up much of the UV-vis spectral range. Therefore, it is crucial to create a method to demarcate the expressed redox transitions for studying these systems. The first portion of these studies...

HEART TISSUE RECONSTRUCTION BY LIGHT-CONTROLLED CELL ADHESION, PATTERNING AND ALIGNMENT ON DECELLULARIZED SCAFFOLDS

Cong Li
There is an urgent demand for engineered tissues and organs because of extremely limited donor tissues available for transplant. The challenge of tissue rejection has motivated many researchers to try to remove all of the cells from a heart and then add back in patient matched cells. These recellularized hearts are a promising avenue towards a functional bioartifical heart that is less likely to be rejected. Decellularized extracellular matrix (ECM) scaffolds generated from animal hearts...

Flame Stabilization of a Premixed Jet in Vitiated Coflow

Tyler Owens
Premixed staged combustion in gas turbine engines can reduce emissions by lowering peak flame temperatures but can also lead to different stability characteristics when compared to traditional combustors. High pressure ratio and subsequently high temperatures can lead to conditions suitable for both autoignition and premixed flame propagation in an environment where spatial fuel/air variations are present. An experimental facility which issues a premixed jet into a coflowing vitiated mixture was studied to examine the stability...

Zappa’s Remembrance of a Forgotten Style: The Relationship Between Frank Zappa and Doo-Wop as Illustrated in Cruising with Ruben & The Jets

Benjamin Adamo
One of Zappa’s many cherished styles of music was the doo-wop of the mid-1950s through the early 1960s. His love for the style culminated in 1968 with a poor-selling and often forgotten doo-wop record, Cruising with Ruben & The Jets. While the record earned little praise from critics and fans, Zappa considered it as a landmark of his early career, as evidenced in his autobiography. This thesis investigates Zappa’s relationship to doo-wop and “perversion” of...

BRIDGING THE GAP

Karen S. Heavin
The contraction of the blue-collar economy is slowly rendering the high school diploma obsolete as an entry-level requirement for middle class employability. Over the last 40 years, jobs requiring some sort of postsecondary education or post-high school credential increased from 28% to 62%, while lower-skilled jobs, traditionally filled by high school graduates or those without a high school diploma, decreased from 72% to 38%. As automation slowly replaces the blue-collar workforce, it is critical that...

Reliability Assessment and Optimization of Water Distribution Systems Explicitly Considering Isolation Valve Locations

Erika Hernandez Hernandez
Water distribution systems have changed the landscape of communities through two services: 1) providing water supply for domestic and industrial use, and 2) providing water required to fight fires. However, a substantial portion of the water infrastructure in the country, as many of other public assets built over 50 years ago, are now reaching the end of their useful life; which combined with rapid growth and changes in demographics have placed water distribution pipe networks...

Characterization and Engineering of Interrupted Adenylation Domains

Taylor Lundy
Nature has historically served as a prolific source of biologically active molecules produced by plants, fungi, and bacteria termed natural products (NPs). These NPs often serve as therapeutic leads due to their structural diversity and unique mechanisms of action. However, many need modifications to make them more effective or safer for human use. This can be a daunting and complicated task to do via traditional organic chemistry because of their complexity, copious stereocenters, and a...

A THERMODYNAMIC AND FEASIBILITY STUDY OF GREEN SOLVENTS FOR THE FABRICATION OF WATER TREATMENT MEMBRANES

Xiaobo Dong
Nonsolvent induced phase separation (NIPS) has been widely used to fabricate polymeric membranes. In NIPS, a polymer is dissolved in a solvent to form a dope solution, which is then cast on a substrate and immersed in a nonsolvent bath, where phase inversion occurs. Petroleum-derived organic solvents, such as N-Methyl-2-Pyrrolidone (NMP) and Dimethylacetamide (DMAc), have been traditionally used to fabricate polymeric membranes via NIPS. However, these solvents may have negative impacts on environmental and human...
