Computational Utilities for the Game of Simplicial Nim

Nelson Penn
Simplicial nim games, a class of impartial games, have very interesting mathematical properties. Winning strategies on a simplicial nim game can be determined by the set of positions in the game whose Sprague-Grundy values are zero (also zero positions). In this work, I provide two major contributions to the study of simplicial nim games. First, I provide a modern and efficient implementation of the Sprague-Grundy function for an arbitrary simplicial complex, and discuss its performance...

Therapeutic Targeting of Leukemia Stem Cells to Prevent T-Cell Acute Lymphoblastic Leukemia Relapse

Meghan Green Haney
The survival rate of T-cell Acute Lymphoblastic Leukemia (T-ALL) relapse is a dismal 10% of affected adults and 30% of children, largely due to the relapsed disease being more aggressive and treatment resistant than the initial disease. Relapse is thought to occur because conventional chemotherapies are unable to reliably eliminate a unique cell type known as leukemia stem (or propagating) cells (LSCs). LSCs are the only cells within the leukemia with the ability to self-renew...

Risk-Based Construction Inspection

Shannon Rush
State Transportation Agencies have been experiencing staffing difficulties in the last couple of decades due to the deterioration of infrastructure and a large number of employees retiring or transitioning to the private sector. Therefore, the STA demographic has become much younger and a loss of critical knowledge has resulted from this changeover. Construction Inspection in particular has been severely impacted. Inspired by the NCHRP Synthesis 450, the Kentucky Transportation Cabinet has initiated the Risk-Based Construction...

OXIDATION PRETREATMENT FOR ENHANCED LEACHABILITY OF RARE EARTH ELEMENTS FROM BITUMINOUS COAL SOURCES

Tushar Gupta
Rare earth elements (REEs) are critical components in advanced electronics, clean energy technologies, and national energy and economic security. The global supply situation of these strategically valuable elements remains critical as the market is largely monopolistic. Thus, to alleviate the dependence on global imports, investments are being made in the research and development of innovative and cost-effective technologies for the indigenous processing and recovery of REEs from alternate sources that are cheap and abundant. Numerous...

PREDICTION OF NOISE EMISSIONS USING PANEL CONTRIBUTION ANALYSIS SUPPLEMENTED WITH SCALE MODELING

Gong Cheng
Panel contribution analysis (PCA) can be used to predict machinery noise emissions, component contributions, and to assess the impact of sound reduction treatments. PCA is a measurement approach that is advantageous for complex machinery that is not easily modeled using conventional numerical analysis approaches. In this research, PCA is combined with scale modeling in order to speed up the necessary measurement work. Moreover, the method can be applied to much larger machinery and noise emissions...

Vibro-Acoustic Codling Moth Larvae Infestation Detection in Apples

Chadwick A. Parrish
Within recent years, the demand for organic produce has greatly increased due to many factors, including increasing knowledge about such things as dietary fiber and balanced gastrointestinal bacterial ecosystems. This increase in demand, coupled with the financial penalties for sending invasive species and pests across borders, presents a need for a scalable and accurate system to non-destructively detect infestation. The proposed work addresses this problem by testing the performance of a non-destructive vibro-acoustic method for...

Optical Metasurfaces

Fatih Balli
Traditional optical elements, such as refractive lenses, mirrors, phase plates and polarizers have been used for various purposes such as imaging systems, lithographic printing, astronomical observations and display technology. Despite their long-term achievements, they can be bulky and not suitable for miniaturization. On the other hand, recent nanotechnology advances allowed us to manufacture micro and nanoscale devices with ultra-compact sizes. Metasurfaces, 2D engineered artificial interfaces, have emerged as candidates to replace traditional refractive lenses with...

THE LIVES OF OTHERS

Nina Marijanovic
This study examined the topic of faculty satisfaction among faculty employed at the University of Sarajevo (UNSA) in Bosnia and Hercegovina (BiH). BiH has endured a difficult transition from a socialist regime to a market economy following the disintegration of Yugoslavia in the early 1990’s and its higher education sector has been particularly affected by this transition. Scholarly research has focused mostly on the impact of discrimination of certain groups at the primary and secondary...

TOWARDS A HOLISTIC RISK MODEL FOR SAFEGUARDING THE PHARMACEUTICAL SUPPLY CHAIN

WASTE HEAT RECOVERY OF INDUSTRIAL REGENERATIVE THERMAL OXIDIZER (RTO), A CASE STUDY

James Jr. Trimpe
Industrial processes that utilize and release hazardous compounds into the atmosphere are required to break down those compounds before exhausting them from their facilities. An industry-recognized method to break down those hazardous compounds is through thermal oxidation. Thermal oxidation is a process where the compounds are exposed to their auto-ignition temperature in an oxygen-rich environment and combust. The output of thermal oxidation is carbon dioxide, water vapor, and heat. Thermal oxidizers are equipment that performs...

PARENT SCHOOL INVOLVEMENT, STUDENT SCHOOL ENGAGEMENT, AND ACADEMIC ACHIEVEMENT IN CHILDREN ADOPTED FROM FOSTER CARE BY LESBIAN AND GAY PARENTS

Cassandra Vázquez
Sparse research has examined academic outcomes of children adopted from foster care by lesbian and gay (LG) parents. Children who have experienced foster care are at greater risk for negative outcomes, but investment in academic achievement could help buffer potential adversity. Parent and student engagement with school peaks in middle childhood, so this may be an important period for understanding processes that influence academic achievement. This study explores how LG parents (N = 57) of...

Investigation of Multidrug Efflux Transporter AcrB in Escherichia coli

Prasangi Rajapaksha
The Resistant Nodulation Division (RND) super family member, tripartite AcrA-AcrB-TolC efflux pump, is a major contributor in conferring multidrug-resistance in Escherichia coli. The structure of the pump complex, and drug translocation by functional rotation mechanism have been widely studied. Despite of all these data, the dynamics of the assembly process of the pump and AcrB during functional rotation in the process of drug efflux remains poorly understood. My thesis focuses on understanding the pump assembly...

Jacob Dunkerson
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States. Each year, an estimated 2.8 million Americans are diagnosed with a TBI due to falling, motor vehicle collisions, gun violence, and sports related concussions. Although inflicted by a single event, the post-traumatic effects of TBI often develop into a life-long disease. Survivors often experience cognitive decline, memory loss, emotional instability, changes in personality, and physical disabilities. A single TBI,...

Factors Associated with Lifestyle Modification for Type 2 Diabetes Self-Management and Prevention

Leigh Koonmen
Diabetes is the seventh leading cause of death in the United States, affecting roughly 13% of U.S. adults aged 18 years or older. Type 2 diabetes accounts for 90-95% of all diabetes cases and is characterized by the progressive development of insulin resistance leading to sustained elevated blood glucose levels. Management of type 2 diabetes includes risk-reduction strategies and continuous medical care to prevent the development of complications. Lifestyle is a major contributing factor to...

Data for: PickMe: sample selection for species tree reconstruction using coalescent weighted quartets

Joseph Rusinko, Yu Cai, Allison Doherty, Katherine Thompson, Julien Boutte, Mark Fishbein & Shannon Straub
After collecting large data sets of many genes for many species for phylogenomics studies, researchers may make ad hoc decisions about which genes or samples to include in a species tree reconstruction analysis based on various parameters, including the amount of missing data. Optimally, sampling would be maximized, but it can be difficult for empiricists to determine where to draw the line for sample inclusion when data sets are incomplete. Under the multispecies coalescent model,...

PREDICTING TOMORROW

Melissa Cantor
The leading causes of morbidity and mortality in preweaned dairy calves are diarrhea and bovine respiratory disease complex (BRD). The delayed detection of these diseases in calves can also delay intervention and disease recovery. The overarching objective of this dissertation was to follow a cohort of calves daily for the first 90 days of life for naturally occurring clinical BRD bouts and diarrheal bouts. The objective answered if feeding behaviors and activity levels were different...

ASSESSING THE USE OF LIDAR AND UAV TECHNOLOGY FOR MONITORING GROWING ALFALFA

Tucker Sheffield
Alfalfa is a popularly grown crop because of its value as a nutritious feed source for livestock. The efficient production of an alfalfa crop relies on the monitoring of certain parameters, like height, quality, and yield. Traditionally, producers have used manual measurements of alfalfa plant height to estimate the nutritive quality and yield of a growing alfalfa crop. Manual measurements of plant height are often labor intensive and provide low resolution data that is not...

EXPLORING THE RELATIONSHIPS BETWEEN CULTURAL VALUES AND DIET PATTERNS AMONG MEXICAN AND CUBAN IMMIGRANTS IN KENTUCKY

Nasreen Omran
The number of Latinx in the U.S. is expected to grow to about 28 percent of the population by the year 2060. As the number of Latinx increases in the U.S. it is important to understand how cultural beliefs influence dietary behaviors as Latinx are disproportionately affected by diet related disease such as diabetes mellitus, cancer, and cardiovascular disease. The aim of this secondary data analysis is to examine the relationship between family values, gender...

STATELESSNESS AND CONTESTED SOVEREIGNTY IN THE MIDDLE EAST

John Perry
This dissertation examines the significance of America’s interactions with stateless actors. It argues that it was groups such as the Muslim Brotherhood, Palestine’s refugees, and ethnic minorities, not the U.S. and Soviet governments, nor the state governments of the region, which dictated how the Cold War unfolded in the Middle East. These groups transformed the policy decisions, strategies, and alliances of both native regimes and the superpowers. Traditionally, historians have looked at the global politics...

THE SOCIAL BEHAVIOR OF PINE SAWFLIES IN THE GENUS NEODIPRION

John Terbot II
Group living is found across the animal kingdom ranging from temporary mating aggregations to complex, eusocial lifestyles. A particularly common form of group living found among insects are larval or nymphal herds. This lifestyle consists of immature insects living together and results in several proposed costs and benefits. Benefits of this lifestyle include improved ability to regulate a group’s microenvironment, more efficient use of their host, and the ability to engage in collective predator defenses....
