Faculty Publications

Disparities and their geospatial patterns exist in morbidity and mortality of COVID-19 patients. When it comes to the infection rate, there is a dearth of research with respect to the disparity structure, its geospatial characteristics, and the pre-infection determinants of risk (PIDRs). This work aimed to assess the temporal-geospatial associations between PIDRs and COVID-19 infection at the county level in South Carolina. We used the spatial error model (SEM), spatial lag model (SLM), and conditional autoregressive model (CAR) as global models and the geographically weighted regression model (GWR) as a local model. The data were retrieved from multiple sources including …

Isolating Detrital And Diagenetic Signals In Magnetic Susceptibility Records From Methane-Bearing Marine Sediments, Joel E. Johnson, Stephen C. Phillips, William C. Clyde, Liviu Giosan, Marta E. Torres

Faculty Publications

Volume-dependent magnetic susceptibility (κ) is commonly used for paleoenvironmental reconstructions in both terrestrial and marine sedimentary environments where it reflects a mixed signal between primary deposition and secondary diagenesis. In the marine environment, κ is strongly influenced by the abundance of ferrimagnetic minerals regulated by sediment transport processes. Post-depositional alteration by H₂S, however, can dissolve titanomagnetite, releasing reactive Fe that promotes pyritization and subsequently decreases κ. Here, we provide a new approach for isolating the detrital signal in κ and identifying intervals of diagenetic alteration of κ driven by organoclastic sulfate reduction (OSR) and the anaerobic oxidation of …

Modeling Of Mos2 Tunnel Field Effect Transistor In Verilog-A For Vlsi Circuit Design, Md Azmot Ullah Khan, Naheem Olakunle Adesina, Jian Xu

Faculty Publications

This paper presents the design of an inverter, half adder, and ring oscillator using compact models of MoS2 channel-based tunnel field effect transistor (TFET). The TFET models (both nand p-type) are written in high-level hardware language Verilog-Analog (Verilog-A) following the analytical model of [1] and the output characteristics of the components are simulated in Cadence/Spectre software. The performance of the designed inverter (a basic building block of VLSI circuit) is analyzed by extracting its different parameters, such as transfer characteristics, power dissipation and consumption, delay, power delay product. The simulated outputs (sum carry) obtained from the half adder circuit exactly …

Automated Drone Detection Using Yolov4, Subroto Singha, Burchan Aydin

Faculty Publications

Drones are increasing in popularity and are reaching the public faster than ever before. Consequently, the chances of a drone being misused are multiplying. Automated drone detection is necessary to prevent unauthorized and unwanted drone interventions. In this research, we designed an automated drone detection system using YOLOv4. The model was trained using drone and bird datasets. We then evaluated the trained YOLOv4 model on the testing dataset, using mean average precision (mAP), frames per second (FPS), precision, recall, and F1-score as evaluation parameters. We next collected our own two types of drone videos, performed drone detections, and calculated the …

Small Studies, Big Decisions: The Role Of Pilot/Feasibility Studies In Incremental Science And Premature Scale-Up Of Behavioral Interventions, Michael William Beets, Lauren Von Klinggraeff, Robert G. Weaver, Bridget Ryan Armstrong, Sarah Burkart

Faculty Publications

Background: Careful consideration and planning are required to establish “sufficient” evidence to ensure an investment in a larger, more well-powered behavioral intervention trial is worthwhile. In the behavioral sciences, this process typically occurs where smaller-scale studies inform larger-scale trials. Believing that one can do the same things and expect the same outcomes in a larger-scale trial that were done in a smaller-scale preliminary study (i.e., pilot/feasibility) is wishful thinking, yet common practice. Starting small makes sense, but small studies come with big decisions that can influence the usefulness of the evidence designed to inform decisions about moving forward with a …

Faculty Publications

Food choice for children has important implications in establishing early-life dietary habits and preferences. Food choice for children has been studied as parent–child dyad dynamics, but little is known about the extended system of relationships in maternal food choice for children. The objective of this study was to understand the functions of mothers' social networks in the food choices that mothers make for their children ages 1 to 5 years old in rural Mexico. In-depth interviews were conducted with 46 participants in three rural communities. The interviews inquired about participants' child-feeding practices, personal and local beliefs about child feeding and …

Investigating Influence Of Geometry And Operating Conditions On Local Current, Concentration, And Crossover In Alkaline Water Electrolysis Using Computational Fluid Dynamics, J. S. Lopata, S-G. Kang, H-S. Cho, C-H. Kim, J. W. Weidner, Sirivatch Shimpalee

Faculty Publications

We use a three-dimensional computational fluid dynamics model to examine the liquid saturation, KOH concentration, and gas crossover in an alkaline diaphragm water electrolysis device. The effects of cell potential, solution feed rate, and aspects of the design such as the locations and widths of channels on performance and crossover were studied. The results build a case for implementing a separator transport model and an electrode/separator interface model because of the concentration changes observed at the anode and cathode. Simulations suggest a strong relationship between solution feed rate and the nature of dissolved gas crossover through the diaphragm due to …

A Southwestern United States Pilot Investigation Of Triatomine–Mite Prevalence, Kyndall C. Dye-Braumuller, Hanna Waltz, Mary K. Lynn, Stephen A. Klotz, Justin O. Schmidt, Alvaro Romero, Marvin Stanley Rodriguez Aquino, Jose Ricardo Palacios Valladares, Pamela Michelle Cornejo Rivas, Melissa Nolan Ph.D., Mph

An estimated 70 million persons in the Western Hemisphere are living at risk for Chagas disease, a parasitic infection transmitted to humans by over 156 different competent triatomine insect vector species. Prior Pan American Health Organization insecticide campaigns throughout Latin America in the 1990s and 2000s demonstrated that domestic insecticide spraying had temporary effects, which resulted in the re-establishment of triatomine species within a few years. Serendipitously, our team found ectoparasitic mites parasitizing triatomines collected from the field in multiple locations in the southwestern United States, where human–triatomine interaction was high but human parasite infection remains low. Upon further investigation …

Predicting Drug Sensitivity Of Cancer Cells Based On Dna Methylation Levels, Sofia P. Miranda, Fernanda A. Baião, Julia L. Fleck, Stephen R. Piccolo

Faculty Publications

Cancer cell lines, which are cell cultures derived from tumor samples, represent one of the least expensive and most studied preclinical models for drug development. Accurately predicting drug responses for a given cell line based on molecular features may help to optimize drug-development pipelines and explain mechanisms behind treatment responses. In this study, we focus on DNA methylation profiles as one type of molecular feature that is known to drive tumorigenesis and modulate treatment responses. Using genome-wide, DNA methylation profiles from 987 cell lines in the Genomics of Drug Sensitivity in Cancer database, we used machine-learning algorithms to evaluate the …

Rationale Severe fetal malnutrition has been related to an increased risk of respiratory diseases later in life, but evidence for the association of a suboptimal diet during pregnancy with respiratory outcomes in childhood is conflicting. We aimed to examine whether a pro-inflammatory or low-quality maternal diet during pregnancy was associated with child's respiratory health.

Methods We performed an individual participant meta-analysis among 18 326 mother–child pairs from seven European birth cohorts. Maternal pro-inflammatory and low-quality diets were estimated by energy-adjusted Dietary Inflammatory Index (E-DII) and Dietary Approaches to Stop Hypertension (DASH) scores. Preschool wheezing and school-age asthma were measured using …

Dreams Interrupted: A Mixed-Methods Research Project Exploring Latino College Completion, Kate Sablosky Elengold, Jess Dorrance, Amanda Martinez, Patricia Foxen, Paul Mihas

Faculty Publications

Latino students are entering college at record numbers; Today, almost 3.8 million Latinos are enrolled in colleges and universities across the United States. Yet Latino students trail their White and Asian peers in attaining college degrees. The overall completion gap exceeds ten percentage points.

Although scholars and advocates have pointed to several different barriers facing Latino college students, a persistent narrative focuses on Latino students’ aversion to taking on student debt. In response, researchers at the University of North Carolina-Chapel Hill and UnidosUS undertook a multi-year mixed-method study to test and interrogate whether and how debt aversion affects Latino college …

Dosimetric Validation Of A System To Treat Moving Tumors Using Scanned Ion Beams That Are Synchronized With Anatomical Motion, Michelle Lis, Wayne Newhauser, Marco Donetti, Moritz Wolf, Timo Steinsberger, Athena Paz, Christian Graeff

Faculty Publications

Purpose: The purpose of this study was to validate the dosimetric performance of scanned ion beam deliveries with motion-synchronization to heterogenous targets. Methods: A 4D library of treatment plans, comprised of up to 10 3D sub-plans, was created with robust and conventional 4D optimization methods. Each sub-plan corresponded to one phase of periodic target motion. The plan libraries were delivered to a test phantom, comprising plastic slabs, dosimeters, and heterogenous phantoms. This phantom emulated range changes that occur when treating moving tumors. Similar treatment plans, but without motion synchronization, were also delivered to a test phantom with a stationary target …

Concurrent Associations Between Expressive Language Ability And Independence In Adolescents And Adults With Fragile X Syndrome, Leonard Abbeduto, Jessica Klusek, Julie Lounds Taylor, Nadia Abdelnur, Nicole Sparapani, Angela John Thurman

Faculty Publications

BACKGROUND: Few individuals with fragile X syndrome (FXS) successfully meet adult normative expectations in education, employment, peer relations, and habitation, although there is within-syndrome variability in this regard. The primary goal of this study was to determine whether expressive language skills contribute to the capacity for independent functioning in adulthood even after controlling for nonverbal cognitive ability. METHODS: Participants were 18- to 23-year-olds with FXS. Expressive language was assessed using the psychometrically validated Expressive Language Sampling (ELS) conversation and narration procedures. The language produced was transcribed and analyzed to yield measures of expressive vocabulary, syntax, and intelligibility. Parents concurrently completed …

Urban Bat Pups Take After Their Mothers And Are Bolder And Faster Learners Than Rural Pups., Lee Harten, Nesim Gonceer, Michal Handel, Orit Dash, H. Bobby Fokidis, Yossi Yovel

Faculty Publications

Background: Urbanization is rapidly changing our planet and animals that live in urban environments must quickly adjust their behavior. One of the most prevalent behavioral characteristics of urban dwelling animals is an increased level of risk-taking. Here, we aimed to reveal how urban fruitbats become risk-takers, and how they differ behaviorally from rural bats, studying both genetic and non-genetic factors that might play a role in the process. We assessed the personality of newborn pups from both rural and urban colonies before they acquired experience outdoors, examining risk-taking, exploration, and learning rates.

Results: Urban pups exhibited significantly higher risk-taking levels, …

Quantifying The Structure Of Residential Water Demand In The United States: A Generalized Exact Affine Stone Index Demand Framework, Bakhtavoryan Rafael, Vardges Hovhannisyan

Faculty Publications

We utilize a Generalized Exact Affine Stone Index system to evaluate the structure of residential water demand that recognizes demand interrelationship between residential and bottled water in the United States, allowing for precommitted consumption. Further, we address expenditure and price endogeneity by accounting for the supply side of the price determination mechanism. A significant substitutability relationship between residential and bottled water is found, while substantial precommitments are established in both residential and bottled water consumption. Residential demand becomes price-elastic once the precommitted level is reached. Finally, ignoring substitutability, precommitments, or endogeneity distorts the demand structure, resulting in erroneous policy implications.

The Power Of Tolerance Vs. Unselfishness As A Cultural Determinant Of Cooperation, Kimmo Eriksson, Brent Simpson, Irina Vartanova

Faculty Publications

Cooperation in collective action problems and resource dilemmas is often assumed to depend on the values of the individuals involved, such as their degree of unselfishness and tolerance. Societal differences in cooperation and cooperative norms may therefore result from cultural variation in emphasis on these personal values. Here we draw on several cross-national datasets to examine whether society-level emphasis on unselfishness and tolerance and respect for other people predict how societies vary in cooperation [in a continuous prisoner’s dilemma (PD)] and in norms governing cooperation [in a common pool resource dilemma (CPR)]. The results suggest that high levels of cooperation …

In this study, a nuclear hybrid energy system (NHES) with large-scale hydrogen storage integrated with a gas turbine cycle is proposed as a flexible system for load following. The proposed system consists of a nuclear reactor, a steam Rankine cycle, a hydrogen electrolyzer, a storage system for hydrogen in an underground salt cavern, and a Brayton cycle that uses hydrogen as fuel to generate additional electricity to meet peak demand. A dynamic mathematical model is developed for each subsystem of the NHES. To evaluate the potential benefits of the system, a one-year study is conducted, using scaled grid demand data …

Isotopic Evidence For Dominant Secondary Production Of Hono In Near-Ground Wildfire Plumes, Jiajue Chai, Jack E. Dibb, Bruce E. Anderson, Claire Bekker, Danielle E. Blum, Eric Heim, Carolyn E. Jordan, Emily E. Joyce, Jackson H. Kaspari, Hannah Munro, Wendell W. Walters, Meredith G. Hastings

Faculty Publications

Nitrous acid (HONO) is an important precursor to hydroxyl radical (OH) that determines atmospheric oxidative capacity and thus impacts climate and air quality. Wildfire is not only a major direct source of HONO, it also results in highly polluted conditions that favor the heterogeneous formation of HONO from nitrogen oxides (NOx= NO + NO2) and nitrate on both ground and particle surfaces. However, these processes remain poorly constrained. To quantitatively constrain the HONO budget under various fire and/or smoke conditions, we combine a unique dataset of field concentrations and isotopic ratios (15N / 14N and 18O / 16O) of NOx …

Leaf Form Diversification In An Ornamental Heirloom Tomato Results From Alterations In Two Different Homeobox Genes, Hokuto Nakayama, Steven D. Rowland, Zizhang Cheng, Kristina Zumstein, Julie Kang, Yohei Kondo, Neelima R. Sinha

Faculty Publications

Domesticated plants display diverse phenotypic traits. However, the influence of breeding effort on this phenotypic diversity remains unknown. Here, we demonstrate that a single nucleotide deletion in the homeobox motif of BIPINNATA, a BEL-LIKE HOMEODOMAIN gene, led to a highly complex leaf phenotype in an heirloom tomato (Solanum lycopersicum), Silvery Fir Tree (SiFT), which is used as a landscaping and ornamental plant. A comparative gene network analysis revealed that repression of SOLANIFOLIA, the ortholog of WUSCHEL RELATED HOMEOBOX 1, caused the narrow leaflet phenotype seen in SiFT. Comparative genomics indicated that the bip mutation in SiFT likely arose de novo …

Electroanalytical Measurements Of Oxide Ions In Molten Cacl2 On W Electrode, Devin Rappleye, Chao Zhang, Art Nelson, Scott Simpson, Michael Simpson

Faculty Publications

The electrochemical interaction of oxide ions with tungsten electrodes in molten calcium chloride (CaCl₂) was analyzed by combining electroanalytical techniques with X-ray photoelectron spectroscopy. During a cyclic voltammetry (CV) scan, the oxide ions appear to interact with the tungsten working electrode via a multi-step oxidation and reduction process. The overall redox peaks behave reversibly up to 750 mV/s. This electrochemical process enables the oxide ion concentration to be correlated to CV oxidation peaks. The resulting correlation agrees well (8.8% difference) with back titration measurements and can be used to monitor oxide content in the salt in real-time during …

Application Of Stoichiometric Hydrogen Atoms For Balancing Organic Combustion Reactions, Pong Kau Yuen, Cheng Man Diana Lau

Faculty Publications

Combustion is a common redox reaction, and organic combustion is one of the basic contents in chemistry curriculum. The transferred H-atom is commonly used as a redox indicator in organic chemistry and biochemistry. Nevertheless, the relationship between the number of transferred H-atoms and the number of transferred electrons has not been fully revealed. Oxidation number (ON) is an electron-counting concept. Without knowing the ONs, the number of transferred electrons cannot be counted and therefore, the redox reactions cannot be classified, defined, and balanced. This paper explores the new H-atom method for counting the number of transferred H-atoms. It provides a …

A Dichotomy Of Sport Sponsorships: Does The Nature Of Competition Among Sponsors Matter?, Thomas Doellman, Brian Walkup, Adrien Bouchet, Brian Chabowski

Faculty Publications

In this paper, we argue that the firm value implications of sport sponsorships for sponsors may depend on the competitive environment during the bidding process for different types of sponsorships. More specifically, we contend that the bidding environment for professional football (soccer) kit sponsorships represents a form of common value auction, while the bidding environment for corporate logo sponsorships on teams’ shirts does not. As common value auctions are prone to winner’s curse, the firm value implications should be different for kit sponsorship announcements than for shirt sponsorship announcements. Our results suggest that shareholders indeed perceive the value derived from …
