Forward Euler Solutions And Weakly Invariant Time-Delayed Systems, Norma L. Ortiz-Robinson, Vinicio R. Ríos

Mathematics and Applied Mathematics Publications

This paper presents a necessary and sufficient condition for the weak invariance property of a time-delayed system parametrized by a differential inclusion. The aforementioned condition generalizes the well-known Hamilton-Jacobi inequality that characterizes weakly invariant systems in the nondelay setting. The forward Euler approximation scheme used in the theory of discontinuous differential equations is extended to the time-delayed context by incorporating the delay and tail functions featuring the dynamics. Accordingly, an existence theorem of weakly invariant trajectories is established under the extended forward Euler approach.

The Influence Of Adhd And Bipolar Disorder Symptoms And Labels On Private High School Teachers’ Accommodations And Attitudes, Sara Kerney

Psychology Honors Papers

The present study examined the effects of symptoms and diagnostic labeling on teachers’ accommodations for and opinions of a student presented in a vignette containing a behavioral description of ADHD or Bipolar Disorder in an adolescent girl. Participants were 85 teachers from five New England private high schools who read a vignette and then answered subsequent questions in an online survey to measure opinions of that student and hypothetical accommodations. Additionally, questions measured participants’ familiarity with mental illness, opinions on mental illness, and beliefs in the causes of the disorders so that the relationship of these variables to accommodations and …

Connectionist-Based Rules Describing The Pass-Through Of Individual Goods Prices Into Trend Inflation In The United States, Richard G. Anderson, Jane M. Binner, Vincent A. Schmidt

United States Air Force: Publications

This paper examines the inflation ‘‘pass-through’’ problem in American monetary policy, defined as the relationship between changes in the growth rates of individual goods and the subsequent economy-wide rate of growth of consumer prices. Initial relationships are established with Granger causality tests robust to structural breaks. A feed forward artificial neural network (ANN) is used to approximate the functional relationship between selected component subindexes and the headline CPI. Moving beyond the ANN ‘‘black box’’, we illustrate how decision rules can be extracted from the network.

Geochemical Evaluation Of High Sulfate Levels In Ponca Creek, Northeastern Nebraska, Jon C. Atkinson

United States Air Force: Publications

Most surface water and shallow groundwater occurring in northeastern Nebraska are of the calcium bicarbonate type, with minor concentrations (e.g., 10–200 mg/L) of sulfate (SO₄). Examination of historical water quality data (major cations and anions) for Ponca Creek, a predominantly ephemeral streamin northeastern Nebraska, revealed that SO₄ concentrations ranged from about 110 to almost 1000mg/L and contribute to a calcium sulfate hydrochemical facies. Consequently, most SO₄ concentrations were above the U.S. Environmental Protection Agency secondary maximum contaminant level in drinking water of 250 mg/L. Sulfate concentrations for the same period for a nearby stream, Verdigre Creek, …

Cooperative Cluster Formation, Dna Bending And Base-Flipping By O6-Alkylguanine-Dna Alkyltransferase, Ingrid Tessmer, Manana Melikishvili, Michael G. Fried

Center for Structural Biology Faculty Publications

O⁶-Alkylguanine-DNA alkyltransferase (AGT) repairs mutagenic O⁶-alkylguanine and O⁴-alkylthymine adducts in DNA, protecting the genome and also contributing to the resistance of tumors to chemotherapeutic alkylating agents. AGT binds DNA cooperatively, and cooperative interactions are likely to be important in lesion search and repair. We examined morphologies of complexes on long, unmodified DNAs, using analytical ultracentrifugation and atomic force microscopy. AGT formed clusters of ≤11 proteins. Longer clusters, predicted by the McGhee–von Hippel model, were not seen even at high [protein]. Interestingly, torsional stress due to DNA unwinding has the potential to limit cluster size …

Families With Hungry Children And The Transition From Preschool To Kindergarten, Colleen Heflin, Irma Arteaga, Sara Gable

University of Kentucky Center for Poverty Research Discussion Paper Series

This paper exploits a source of variation in the eligibility for federal nutrition programs to identify the program effects on food insecurity. Children are eligible for the WIC program until the day before they turn 61 months old. The result is an age discontinuity in program participation at the 61-month cutoff. Using the Early Childhood Longitudinal Study Birth-cohort dataset, we find strong evidence of a sizeable increase in household food insecurity at the 61- month cutoff. Our findings are robust to different model specifications, datasets, and various bandwidth choices using various non-parametric estimations.

The misuse of prescription drugs for non-medical purposes is a risk to public health and safety. The rates of misuse and diversion of prescription drugs have nearly doubled since the 1990s. This project explored the importance of educating Nurse Practitioners (NPs) in North Carolina (NC) regarding the registration and utilization of the North Carolina Controlled Substances Reporting System (NCCSRS). This reporting system was designed to identify and prevent diversion and to reduce morbidity and mortality of unintentional drug overdoses among primary care patients. A website was developed to showcase the multiple benefits and encourage registration and utilization of the NCCSRS …

Barriers To Diabetes Self-Management In African American Women, Christine Little-Gregory

Nursing Theses and Capstone Projects

Diabetes is a global epidemic and is a leading cause of disease-related death. In the United States, diabetes is the most common chronic disease affecting 23.6 million Americans or 7.8% of the population (Centers for Disease Control, 2010a). African American women have the highest prevalence of diabetes. Health promotion in the form of diabetes self-management is the key to reducing this urgent disparity. This descriptive study sought to identify barriers to diabetes self-management and identify relationships associated with self-management in this population. This study was conducted using a convenience sampling of African American women with diabetes who were surveyed to …

The Role Of Modern Zoos In Wildlife Conservation: From The Wcs To The Wild, John Scott

Student Theses 2001-2013

The reality of the modern world is that humanity is increasing its population rapidly, and demanding more resources than the earth can provide. Humans are utilizing resources like water and fossil fuels, and are in turn polluting and causing a shift in the global climate. Most importantly, humans are taking previously untouched land and utilizing it for living space or agriculture. Therefore there is very little “wild” left after human consumption, and this rapid consumption is adversely affecting all other animal species on this planet. With little food of their own or territory to roam, many species begin their dramatic …

Modeling And Analysis Of Cascading Effects Of Weapons Of Mass Destruction (Wmd) Events On Critical Infrastructure Systems, Sliman Amrani Joutei

Theses

This research studies how the global network behaves after a Weapon of Mass Destruction (WMD) attack. The goal is to find a reliable model that will help capture the behavior of the network in the event of a WMD attack and then proceed to a systematic analysis of that model. We discuss a hierarchical model that visualizes how a WMD attack will impact different infrastructure systems. The second level of the Hierarchical Fault Model (HFM) illustrates the failure propagation from one Critical Infrastructure System (CIS) to another CIS. Next, we construct a stochastic Petri Net for HFM of which we …

Quality Of Life Of Families With Children Who Have Severe Developmental Disabilities: A Comparison Based On Child Residence, Joni Taylor Mcfelea, Sharon Raver

Communication Disorders & Special Education Faculty Publications

This study measured the quality of life of two groups of families with children who had severe developmental disabilities-families whose child lived at home and families whose child lived in a residential facility. Participants were 54 primary caregivers of children who had severe intellectual disabilities and who lacked the ability to both ambulate without assistance and communicate conversationally. Participants completed the "Family Quality of Life Scale" (Hoffman, Marquis, Poston, Summers, & Turnbull, 2006). Analyses revealed that both groups rated their family quality of life (FQOL) as exemplary. FQOL was higher in the family home group than in the residential facility …

The U.S. Environmental Protection Agency (USEPA) has been encouraging states to accerlate their efforts in developing numeric nutrient criteria to promulgate within respective water quality standards and regulations. Based on USEPA recommendations, many states are pursuing nutrient criteria development by assessing frequency distributions and stressor‐response relationships in historical databases, various special studies and the literature. The mini‐workshops described here were targeted toward state agency personnel and stakeholder groups with an interest in understanding statistical techniques that could be used to aide, guide and support numeric nutrient criteria. An initial workshop was conducted at the USEPA Regional Technical Assistance Group meeting …

Sestonic Chlorophyll-A And Nutrient Relationships Across The Red River Basin, Usa, Brian E. Haggard, J. Thad Scott, Scott D. Longing, John T. Metrailer

Arkansas Water Resources Center Technical Reports

The Red River is a trans‐boundary, multi‐jurisdictional basin, where water‐quality standards often change at the state lines. The state agencies with USEPA Region VI focused resources to organize water‐quality data from within this basin and have it statistically analyzed to evaluate the relationships between nutrients and sestonic chlorophyll‐a (chl‐a). There were 152 sites within the Red River Basin that had nutrient and sestonic chl‐a data, and these sites were narrowed down to 132 when a minimum number of observations was required. Sestonic chl‐a levels increased with increasing nutrient concentrations; these significant regressions were used to predict nutrient concentrations at 10 …

Water quality trends were analyzed using flow‐adjusted constituent concentrations of phosphorus, nitrogen, sediment, sulfate and chloride, and parametric and non‐parametric statistical techniques …

Exploring Simple Algorithms For Estimating Gross Primary Production In Forested Areas From Satellite Data, Hirofumi Hashimoto, Weile Wang, Cristina Milesi, Michael A. White, Sangram Ganguly, Minoru Gamo, Ryuichi Hirata, Ranga B. Myneni, Ramakrishna R. Nemani

School of Natural Sciences Faculty Publications and Presentations

Algorithms that use remotely-sensed vegetation indices to estimate gross primary production (GPP), a key component of the global carbon cycle, have gained a lot of popularity in the past decade. Yet despite the amount of research on the topic, the most appropriate approach is still under debate. As an attempt to address this question, we compared the performance of different vegetation indices from the Moderate Resolution Imaging Spectroradiometer (MODIS) in capturing the seasonal and the annual variability of GPP estimates from an optimal network of 21 FLUXNET forest towers sites. The tested indices include the Normalized Difference Vegetation Index (NDVI), …

Assessment Of Pulmonary Fibrogenic Potential Of Multiwalled Carbon Nanotubes In Human Lung Cells, Anurag Mishra, Yon Rojanasakul, Bean T. Chen, Vincent Castranova, Robert R. Mercer, Liying Wang

Faculty & Staff Scholarship

Multiwalled carbon nanotubes have been shown to possess unusual fibrogenic activity in vivo and are currently the focus of intense toxicological investigations. This study further determines the fibrogenic potential of well-dispersed MWCNT in human lung cell culture models and to develop a novel platform for understanding the cellular mechanisms of MWCNT-induced lung fibrosis. Survanta, a natural lung surfactant, showed effectiveness in dispersing agglomerates of MWCNT to fine structures similar in size to aerosolized one. At relevant low doses (0.002–0.2 μg/cm2), MWCNT exhibited a dose-dependent bio-effect on the human lung epithelial cells which is more pronounced in dispersed-MWCNT compared to non-dispersed …

Heritable Patterns Of Tooth Decay In The Permanent Dentition: Principal Components And Factor Analyses, John R. Shaffer, Eleanor Feingold, Xiaojing Wang, Karen Tcuenco, Daniel E. Weeks, Rebecca S. Desensi, Deborah E. Polk, Steve Wendell, Robert J. Weyant, Richard Crout, Daniel W. Mcneil, Mary L. Marazita

Faculty & Staff Scholarship

Background

Dental caries is the result of a complex interplay among environmental, behavioral, and genetic factors, with distinct patterns of decay likely due to specific etiologies. Therefore, global measures of decay, such as the DMFS index, may not be optimal for identifying risk factors that manifest as specific decay patterns, especially if the risk factors such as genetic susceptibility loci have small individual effects. We used two methods to extract patterns of decay from surface-level caries data in order to generate novel phenotypes with which to explore the genetic regulation of caries.

Methods

The 128 tooth surfaces of the permanent …

Genes Involved In Sex Pheromone Discrimination In Drosophila Melanogaster And Their Background-Dependent Effect, Benjamin Houot, Stephane Fraichard, Ralph J. Greenspan, Jean-Francois Ferveur

Faculty & Staff Scholarship

Mate choice is based on the comparison of the sensory quality of potential mating partners, and sex pheromones play an important role in this process. In Drosophila melanogaster, contact pheromones differ between male and female in their content and in their effects on male courtship, both inhibitory and stimulatory. To investigate the genetic basis of sex pheromone discrimination, we experimentally selected males showing either a higher or lower ability to discriminate sex pheromones over 20 generations. This experimental selection was carried out in parallel on two different genetic backgrounds: wild-type and desat1 mutant, in which parental males showed high and …

Microrna-221 Modulates Rsv Replication In Human Bronchial Epithelium By Targeting Ngf Expression, Sreekumar Othumpangat, Cheryl Walton, Giovanni Piedimonte

Faculty & Staff Scholarship

Background

Early-life infection by respiratory syncytial virus (RSV) is associated with aberrant expression of the prototypical neurotrophin nerve growth factor (NGF) and its cognate receptors in human bronchial epithelium. However, the chain of events leading to this outcome, and its functional implications for the progression of the viral infection, has not been elucidated. This study sought to test the hypothesis that RSV infection modulates neurotrophic pathways in human airways by silencing the expression of specific microRNAs (miRNAs), and that this effect favors viral growth by interfering with programmed death of infected cells.

Methodology

Human bronchial epithelial cells infected with green …
