Electrochemiluminescence Mechanisms Investigated With Smartphone-Based Sensor Data Modeling, Parameter Estimation And Sensitivity Analysis, Elmer Ccopa Rivera, Rodney Lee Summerscales, Padma P. Tadi Uppala, Hyun J. Kwon

Faculty Publications

The present study introduces a unified framework combining a mechanistic model with a genetic algorithm (GA) for the parameter estimation of electrochemiluminescence (ECL) kinetics of the Ru(bpy)₃²⁺/TPrA system occurring in a smartphone‐based sensor. The framework allows a straightforward solution for simultaneous estimation of multiple parameters which can be, otherwise, time‐consuming and lead to non‐convergence. Model parameters are estimated by achieving a high correlation between the model prediction and the measured ECL intensity from the ECL sensor. The developed model is used to perform a sensitivity analysis (SA), which provides quantitative effects of the model parameters on the …

Knowledge, Interest, And Motivations Surrounding Self-Managed Medication Abortion Among Patients At Three Texas Clinics, Abigail R.A. Aiken, Kathleen Broussard, Dana M. Johnson, Elisa Padron, Jennifer E. Starling, James G. Scott

Faculty Publications

Background: A rapid increase in restrictive abortion legislation in the United States has sparked renewed interest in self-managed abortion as a response to clinic access barriers. Yet little is known about knowledge of, interest in, and experiences of self-managed medication abortion among patients who obtain abortion care in a clinic.

Objectives: We examined patients’ knowledge of, interest in, and experience with self-managed medication abortion before presenting to the clinic. We characterized the clinic- and person-level factors associated with these measures. Finally, we examined the reasons why patients express an interest in or consider self-management before attending the clinic.

Theories Of Prosecution, Jeffrey Bellin

Faculty Publications

For decades, legal commentators sounded the alarm about the tremendous power wielded by prosecutors. Scholars went so far as to identify uncurbed prosecutorial discretion as the primary source of the criminal justice system’s many flaws. Over the past two years, however, the conversation shifted. With the emergence of a new wave of “progressive prosecutors,” scholars increasingly hail broad prosecutorial discretion as a promising mechanism for criminal justice reform.

The abrupt shift from decrying to embracing prosecutorial power highlights a curious void at the center of criminal justice thought. There is no widely accepted normative theory of the prosecutorial role. As …

Conservative Minimalism And The Consumer Financial Protection Bureau, Jonathan H. Adler

Faculty Publications

While Chief Justice Roberts's votes do not hew closely to what either conservatives or progressives would have preferred, it is a mistake to assume the chief justice has been arbitrary or inconsistent. Rather, the October 2019 Term offered further confirmation that Chief Justice Roberts is a conservative minimalist. While his jurisprudential orientation remains quite conservative, he prefers narrow rulings over sweeping judgments. "If it's not necessary to decide more to dispose of a case, in my view it is necessary not to decide more," he explained in his confirmation hearings. At the same time, Chief Justice Roberts is reluctant to …

“Wicked Traditions” And “Cunning Arts”: Wise Men, Sorcery, And Metalwork In Nephite Society, Dan Belnap, Daniel L. Belnap, Daniel Belnap, Dan Belnap

Faculty Publications

In the ninetieth year of the reign of the judges, four years after the ministry of Samuel the Lamanite, the “great signs and wonders” that he had prophesied of concerning the coming of Christ began to appear. Yet even as they convinced some, others expressed doubt as to what the signs meant, believing instead that the coming of Christ was a “wicked tradition, which has been handed down unto us by our fathers, to cause us that we should believe in some great and marvelous thing which should come to pass . . . therefore they can keep us in …

Change In Implicit Alcohol Associations Over Time: Moderation By Drinking History And Gender, Scott A. Baldwin, Kristen P. Lindgren, Kirsten P. Peterson, Reinout W. Wiers, Bethany A. Teachman

Faculty Publications

Implicit measures of alcohol-related associations or implicit alcohol associations are associated with drinking outcomes over time and can be understood as vulnerability markers for problem drinking. Longitudinal research remains rare, leaving open questions about how implicit alcohol associations themselves change over time and what factors moderate that change. We examined these questions with data from a larger study of first and second year U.S. college students. We investigated how these implicit alcohol associations change over time and potential moderators of those changes (gender, lifetime drinking history, family history of problem drinking, and class standing). A sample of 506 students (57% …

Exploring The Louisiana Purchase And Its Borderlands: The Lewis And Clark, Hunter And Dunbar, Zebulon Pike, And Freeman And Custis Expeditions In Perspective [Part 1], Jay H. Buckley

Faculty Publications

When Americans contemplate the exploration of the Louisiana Purchase, the names Meriwether Lewis and William Clark quickly come to mind. Their historic journey was well conceived, well executed, and well documented. It was one of the first and longest U.S. government-backed explorations of the American West. The name Zebulon Pike, for some, conjures up notions of a lost explorer who was arrested by the Spanish as an alleged American spy. Fewer still have heard of the names William Dunbar, George Hunter, Thomas Freeman, and Peter Custis. Even those who have heard of these men may be hard-pressed to identify any …

“They Are Of Ancient Date”: Jaredite Traditions And The Politics Of Gadianton’S Dissent, Dan Belnap, Daniel L. Belnap

Faculty Publications

In 2018 Abinadi: He Came Among Them in Disguise was published as what was hoped would be the first in a series of volumes by the Book of Mormon Academy (BOMA).1 Established in 2013 at Brigham Young University, this consortium of Religious Education faculty was created to foster critical thinking about the Book of Mormon and to make their academic, theological, and pedagogical research available to the wider public through publications and presentations. This second volume in the series, Illuminating the Jaredite Records, continues that tradition by exploring the Jaredite record and its impact on the later Nephite and Lamanite …

Expertise In Political Contexts: Latour Avec The Third Wave In Science And Technology Studies, David S. Caudill

Faculty Publications

The interdiscipline of science and technology studies (‘STS’) has been characterized by its descriptive analyses of the presumptions and practices of scientific communities, and by numerous theoretical internal debates over the proper framework of analysis of science. While STS has not been characterized by a powerful effect on law and government, both of which are consumers of scientific expertise, an opportunity arises for engagement in public policy disputes due to the willful ignorance regarding science in the Trump administration, and the negative effects of political agendas and conflicts of interest therein. The urgent need for reliable expertise in such political …

Through-The-Wall Radar Detection Using Machine Learning, Aihua W. Wood, Ryan Wood, Matthew Charnley

Faculty Publications

This paper explores the through-the-wall inverse scattering problem via machine learning. The reconstruction method seeks to discover the shape, location, and type of hidden objects behind walls, as well as identifying certain material properties of the targets. We simulate RF sources and receivers placed outside the room to generate observation data with objects randomly placed inside the room. We experiment with two types of neural networks and use an 80-20 train-test split for reconstruction and classification.

Residual-Based Multi-Filter Methodology For All-Source Fault Detection, Exclusion, And Performance Monitoring, Juan Jurado, John F. Raquet, Christine M. Schubert Kabban Air Force Institute Of Technology, Jonathon S. Gipson

Faculty Publications

All-source navigation has become increasingly relevant over the past decade with the development of viable alternative sensor technologies. However, as the number and type of sensors informing a system increases, so does the probability of corrupting the system with sensor modeling errors, signal interference, and undetected faults. Though the latter of these has been extensively researched, the majority of existing approaches have constrained faults to biases and designed algorithms centered around the assumption of simultaneously redundant, synchronous sensors with valid measurement models, none of which are guaranteed for all-source systems. As part of an overall all-source assured or resilient navigation …

High-Fidelity Modeling Of Multirotor Aerodynamic Interactions For Aircraft Design, Eduardo Alvarez, Andrew Ning

Faculty Publications

Electric aircraft technology has enabled the use of multiple rotors in novel concepts for urban air mobility. However, multirotor configurations introduce strong aerodynamic and aeroacoustic interactions that are not captured through conventional aircraft design tools. In this paper we explore the capability of the viscous vortex particle method (VPM) to model multirotor aerodynamic interactions at a computational cost suitable for conceptual design. A VPM-based rotor model is introduced along with recommendations for numerical stability and computational efficiency. Validation of the individual rotor is presented in both hovering and forward-flight configurations at low, moderate, and high Reynolds numbers. Hovering multirotor predictions …

The Invisible Message, Andrew S. Gibbons Iii, Elizabeth Boling

Faculty Publications

The number and variety of messages conveyed by an instructional experience is astonishing, but most designers are unaware of their number, subtlety, and impact. Many of those messages they would not choose to send if they recognized their existence in practice. The design of invisible and abstract message structures receives less attention from designers today than those parts of the design given to more vivid, colorful, and showy surface structures. Invisible message structures work behind the scenes to produce the smooth surface performances in front of the curtain; they are seldom seen directly, but their power is indisputable. The purpose …

Air Quality Improvement During Triple-Lockdown In The Coastal City Of Kannur, Kerala To Combat Covid-19 Transmission, C. T. Resmi, T. Nishanth, M. K. Satheesh Kumar, M. G. Manoj, M. Balachandramohan, K. T. Valsaraj

Faculty Publications

The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year has since become the COVID-19 pandemic across all continents. To restrict the spread of the virus pandemic, the Government of India imposed a lockdown from 25 March 2020. In India, Kannur district was identified as the first "hotspot" of virus transmission and a "triple-lockdown" was implemented for a span of twenty days from 20 April 2020. This article highlights the variations of surface O-3, NO, NO2, CO, SO2, NH3, VOC's, PM10, PM2.5 and meteorological parameters at the time of pre-lockdown, lockdown and triple-lockdown days at Kannur …

Longitudinal Links Between Parents’ Mental Health, Parenting, And Adolescents’ Mental Health: Moderation By Adolescent Sex, Laura M. Padilla-Walker, Hannah B. Apsley

Faculty Publications

This study explored mothering and fathering as possible mediators of the relationship between parent and adolescent mental health concerns and considered the adolescents’ biological sex as a potential moderator. Using structural equation modeling, the longitudinal links between parents’ mental health, parental psychological control, parent-adolescent connectedness, and adolescent mental health in 500 families— including 338 fathers and 500 mothers—were explored over the course of 5 years. The mean age of the adolescents (51.8% female, 69.6% European American) at Time 1 was 13.3 years. Mothers’ symptoms of anxiety directly predicted girls’ depression 5 years later. This relation was not mediated by parenting …

Attosecond Synchronization Of Extreme Ultraviolet High Harmonics From Crystals, Giulio Vampa, Jian Lu, Yong Sing You, Denitsa R. Baykusheva, Mengxi Wu, Hanzhe Liu, Kenneth J. Schafer, Mette B. Gaarde, David A. Reis, Shambhu Ghimire

Faculty Publications

The interaction of strong near-infrared (NIR) laser pulses with wide-bandgap dielectrics produces high harmonics in the extreme ultraviolet (XUV) wavelength range. These observations have opened up the possibility of attosecond metrology in solids, which would benefit from a precise measurement of the emission times of individual harmonics with respect to the NIR laser field. Here we show that, when high-harmonics are detected from the input surface of a magnesium oxide crystal, a bichromatic probing of the XUV emission shows a clear synchronization largely consistent with a semiclassical model of electron-hole recollisions in bulk solids. On the other hand, the bichromatic …

The Effect Of Fiction On Religious Studies Display Shelves In An Academic Library, Marissa Bischoff, Gerrit Van Dyk

Faculty Publications

The religious studies librarians at Brigham Young University (BYU) began a book display research project to examine the circulation rates of religious studies titles placed on display and to specifically evaluate the impact of religious fiction on that display in an academic library. Student employees were tasked with curating the displays over several years and maintaining a spreadsheet with the titles displayed and resulting checkout rates. Religious fiction (from The Church of Jesus Christ of Latter-day Saint tradition) circulated over 80% the first three years, higher than the religious nonfiction on display and the same genre in the stacks. In …

Effect Of Dilution On Sedimentational Separation Of Bacteria From Blood, Clifton M. Anderson, William G. Pitt

Faculty Publications

Bacteria must be separated from septic whole blood in preparation for rapid antibiotic susceptibility tests. This work improves upon past work isolating bacteria from whole blood by exploring an important experimental factor: Whole blood dilution. Herein, we use the continuity equation to model red blood cell sedimentation and show that overall spinning time decreases as the blood is diluted. We found that the bacteria can also be captured more efficiently from diluted blood, up to approximately 68 ± 8% recovery (95% confidence interval). However, diluting blood both requires and creates extra fluid that end users must handle; an optimal dilution, …

Cost Of Quantum Entanglement Simplified, Xin Wang, Mark M. Wilde

Faculty Publications

Quantum entanglement is a key physical resource in quantum information processing that allows for performing basic quantum tasks such as teleportation and quantum key distribution, which are impossible in the classical world. Ever since the rise of quantum information theory, it has been an open problem to quantify entanglement in an information-theoretically meaningful way. In particular, every previously defined entanglement measure bearing a precise information-theoretic meaning is not known to be efficiently computable, or if it is efficiently computable, then it is not known to have a precise information-theoretic meaning. In this Letter, we meet this challenge by introducing an …

N 6-Methyladenine In Dna Antagonizes Satb1 In Early Development, Zheng Li, Shuai Zhao, Raman V. Nelakanti, Kaixuan Lin, Tao P. Wu, Myles H. Alderman, Cheng Guo, Pengcheng Wang, Min Zhang, Wang Min, Zongliang Jiang, Yinsheng Wang, Haitao Li, Andrew Z. Xiao

Faculty Publications

© 2020, The Author(s), under exclusive licence to Springer Nature Limited. The recent discovery of N6-methyladenine (N6-mA) in mammalian genomes suggests that it may serve as an epigenetic regulatory mechanism1. However, the biological role of N6-mA and the molecular pathways that exert its function remain unclear. Here we show that N6-mA has a key role in changing the epigenetic landscape during cell fate transitions in early development. We found that N6-mA is upregulated during the development of mouse trophoblast stem cells, specifically at regions of stress-induced DNA double helix destabilization (SIDD)2–4. Regions of SIDD are conducive to topological stress-induced unpairing …

Gravitation In Terms Of Observables 2: The Algebra Of Fundamental Observables, Rodolfo Gambini, Saeed Rastgoo, Jorge Pullin

Faculty Publications

In a previous paper, we showed how to use the techniques of the group of loops to formulate the loop approach to gravity proposed by Mandelstam in the 1960's. Those techniques allow to overcome some of the difficulties that had been encountered in the earlier treatment. In this approach, gravity is formulated entirely in terms of Dirac observables without constraints, opening attractive new possibilities for quantization. In this paper we discuss the Poisson algebra of the resulting Dirac observables, associated with the intrinsic components of the Riemann tensor. This provides an explicit realization of the non-local algebra of observables for …

Background: Although native to North America, the invasion of the aphid-like grape phylloxera Daktulosphaira vitifoliae across the globe altered the course of grape cultivation. For the past 150 years, viticulture relied on grafting-resistant North American Vitis species as rootstocks, thereby limiting genetic stocks tolerant to other stressors such as pathogens and climate change. Limited understanding of the insect genetics resulted in successive outbreaks across the globe when rootstocks failed. Here we report the 294-Mb genome of D. vitifoliae as a basic tool to understand host plant manipulation, nutritional endosymbiosis, and enhance global viticulture. Results: Using a combination of genome, RNA, …

Microbial Diversity Drives Carbon Use Efficiency In A Model Soil, Luiz A. Domeignoz-Horta, Grace Pold, Xiao-Jun Allen Liu, Serita D. Frey, Jerry M. Melillo, Kristen M. Deangelis

Faculty Publications

Empirical evidence for the response of soil carbon cycling to the combined effects of warming, drought and diversity loss is scarce. Microbial carbon use efficiency (CUE) plays a central role in regulating the flow of carbon through soil, yet how biotic and abiotic factors interact to drive it remains unclear. Here, we combine distinct community inocula (a biotic factor) with different temperature and moisture conditions (abiotic factors) to manipulate microbial diversity and community structure within a model soil. While community composition and diversity are the strongest predictors of CUE, abiotic factors modulated the relationship between diversity and CUE, with CUE …

Using a new approach that constrains thermodynamic modeling of aerosol composition with measured gas-to-particle partitioning of inorganic nitrate, we estimate the acidity levels for aerosol sampled in the South Korean planetary boundary layer during the NASA/NIER KORUS-AQ field campaign. The pH (mean ± 1σ = 2.43 ± 0.68) and aerosol liquid water content determined were then used to determine the chemical regime of the inorganic fraction of particulate matter (PM) sensitivity to ammonia and nitrate availability. We found that the aerosol formation is always sensitive to HNO3 levels, especially in highly polluted regions, while it is only exclusively sensitive to …
