Explaining Nonmerger Gamma-Ray Bursts And Broad-Lined Supernovae With Close Binary Progenitors With Black Hole Central Engines, Christopher L. Fryer, Eric Burns, Anna Y.Q. Ho, Alessandra Corsi, Amy Y. Lien, Daniel A. Perley, Jada L. Vail, V. Ashley Villar

Faculty Publications

For over 25 yr, the origin of long-duration gamma-ray bursts (lGRBs) has been linked to the collapse of rotating massive stars. However, we have yet to pinpoint the stellar progenitor powering these transients. Moreover, the dominant engine powering the explosions remains open to debate. Observations of both lGRBs, supernovae associated with these GRBs, such as broad-line (BL) stripped-envelope (type Ic) supernovae (hereafter, Ic-BL), supernovae (SNe), and perhaps superluminous SNe, fast blue optical transients, and fast x-ray transients, may provide clues to both engines and progenitors. In this paper, we conduct a detailed study of the tight-binary formation scenario for lGRBs, …

Adsorption And Electron Transfer Of Metal-Reducing Decaheme Cytochrome Protein Mtrf On Iron Oxide Nanoparticle Surfaces, Jiahuiyu Fang, Pranab Sarker, Xiaoxue Qin, Shuting Zhang, Size Zheng, Tao Wei

Faculty Publications

Dissimilatory metal-reducing bacteria (DMRB) transfer electrons to extracellular metal oxides via a multiheme cytochrome network. Coupling DMRB with iron oxide nanoparticles (NPs) enables continuous redox processes for various applications such as bioremediation and bioenergy. The conformation of the terminal decaheme cytochrome MtrF on the surface critically influences electron transfer (ET) efficiency. In this work, we used molecular dynamics simulations and master equations to study MtrF adsorption on 3.6 and 6.0 nm α-Fe2O3 NPs and its steady-state ET in water. Our study shows that the heme cofactors can have strong electrostatic interactions with iron oxide NP surfaces, promoting protein adsorption and …

Changes In Aggressive Behaviors Over Time In Children With Adverse Childhood Experiences: Focusing On The Role Of School Connectedness, Sei-Young Lee, Mijin Choi

Faculty Publications

Previous research has found the link between adverse childhood experiences (ACEs) and externalizing behaviors later in adolescence and adulthood. However, limited studies have explored longitudinal trajectories of aggressive behaviors affected by ACEs. This study aimed to investigate how aggressive behaviors change over time and compare the trajectories of aggressive behaviors between children with three or fewer (low-risk ACEs) and those with four or more ACEs (high-risk ACEs) with the role of school connectedness on the trajectories of aggressive behaviors over time. The study sample consisted of 4231 children collected by the Future of Families and Child Wellbeing Study, a longitudinal …

Christian Beliefs About Salvation: Measurement And Associations With Mental Health And Well-Being, Anthony Edward Rose, Timothy B. Smith

Faculty Publications

Religious beliefs influence many behaviors and perspectives relevant to wellbeing and mental health. In Christianity, beliefs about how one attains salvation may be particularly relevant to psychology, but limited scholarship has considered cognitive aspects of religiosity. This study developed and evaluated a new measure of Beliefs about Salvation (BAS) that assesses affirmations of salvation (a) by God’s grace alone and (b) by God’s grace after human repentance/ordinances, as understood by different Christian denominations. We examined the association of the BAS with three measures of mental health and six measures of influences on religiosity. In a sample of 1556 predominantly members …

Relocation Post-Dobbs Among Clinicians Providing Abortions, Dana Howard, Marta Bornstein Phd, Mph, Jocelyn Wascher, Alison H. Norris, Katherine Rivlin

Faculty Publications

Introduction

Intensifying state-level abortion restrictions following the Dobbs v Jackson Women’s Health Organization (2022) decision could lead clinicians to leave states that ban abortion.¹ While large-scale changes are not yet apparent among obstetrician-gynecologists, the abortion care workforce may be uniquely at risk.² We examined the proportion of abortion-providing clinicians who changed primary state of practice, comparing those who left states that banned abortion with those who left states that did not ban abortion after Dobbs, and the ban status of the states to which they relocated.

Methods

This survey study was approved by The Ohio State University …

Human Gut Commensal Alistipes Timonensis Modulates The Host Lipidome And Delivers Anti-Inflammatory Outer Membrane Vesicles To Suppress Colitis In An Il10-Deficient Mouse Model, Ethan Older, Mary K. Mitchell, Andrew Campbell, Xiaoying Lian, Michael Madden, Yuzhen Wang, Lauren E. Van De Wal, Thelma Zaw, Brandon N. Vanderveen, Rodney Tatum, E. Angela Murphy, Yan-Hua Chen, Daping Fang, Melissa Ellermann, Jie Li

Faculty Publications

Correlative studies have linked human gut microbes to specific health conditions. Alistipes is one such microbial genus negatively linked to inflammatory bowel disease (IBD). However, the protective role of Alistipes in IBD is understudied, and the underlying molecular mechanisms remain unknown. In this study, colonization of Il10-deficient mice with Alistipes timonensis DSM 27924 delays colitis development. Colonization does not significantly alter the gut microbiome composition, but instead shifts the host plasma lipidome, increasing phosphatidic acids while decreasing triglycerides. Outer membrane vesicles (OMVs) derived from Alistipes are detected in the plasma of colonized mice, carrying potentially immunomodulatory metabolites into the …

An International Perspective On Geography Curricula: Paving A Way Forward For Geographical Thinking, Tomáš Bendl, Hilde Storrøsæter, Lene Møller Madsen, David Trokšiar, Raphaële De La Martinière, Shanshan Liu, Sizakele Serame, Jerry T. Mitchell, Péter Bagoly-Simó, Yushan Duan, Gillian Kidman

Faculty Publications

Geographical thinking is a cornerstone of modern geography education. Despite its universal value, no large-scale international study has systematically examined its integration into diverse curricular documents. This study investigates how geographical thinking is embedded in the curricula of nine countries, focusing on content and procedural dimensions. Using a structured analytical framework, the research reveals significant patterns and gaps, particularly the underrepresentation of place as a central concept, the lack of explicit focus on geographical thinking, and the limited emphasis on its procedural dimension. The findings emphasise the need for stronger interconnections between these dimensions to promote a more comprehensive approach …

Student Use Of Public Access Computers In The Library: A 10-Year Comparison Study, Holt Zaugg

Faculty Publications

Why did you do this activity, project, or research?

In 2014, across the BYU campus, the use of student-accessible public computer labs was declining. At this time, the library was not experiencing this decline; rather, public computer use in the library was increasing. Ten years later, we re-administered a similar survey in the same manner to determine what, if any, changes occurred.

How did you do this?

Initially (2014), we used a pop-up survey to help determine similarities and differences. When students logged on to a library computer, an invitation to participate in the survey popped up with the option …

Shedding Light On Inequities Of Power Outages Through Data Transparency, Kelly A. Stevens, Sanam K. Aksha, Mohammed Siddiqur Rahman, Elizabeth Trader, Herbert Longenecker, Rebecca Entress

Faculty Publications

In a changing climate, the electricity grid is increasingly exposed to more extreme weather that results in significant power outages. Further, lower income and racial-ethnic minority households are more likely to experience a higher frequency and duration of power outages compared to less socially vulnerable groups. The literature on the unequal impacts of power outages is a new, growing area of research that has been stymied in part due to the difficulty acquiring high spatial resolution, historical power outage data from utilities. In this Perspectives article, we review the availability of power outage data, and what can be learned from …

New Definitions Of Library Use: Experimentation, Discovery, And Creation (Edc) Within A Library, Holt Zaugg

Faculty Publications

Why did you do this activity, project, or research?

Over the last decade, libraries have shifted from being primarily repositories for information and resources to active learning centers. Physical resources (e.g., books, journals, manuscripts) have moved to online access. Librarian roles have adjusted how they help patrons find and access resources in their local library and beyond, resulting in impactful input on research, learning, and scholarly endeavors. Additionally, due to a reduced need for storing materials, libraries have developed collaborative and innovative spaces to meet patrons’ needs. These spaces include group study rooms, experiential studios, makerspaces, green rooms, and podcast …

Prescribed Fire Leads A Pine Flatwoods Specialist Tree Frog To Seek Local Refugia, Ian Biazzo, Pedro F. Quintana-Ascencio

Faculty Publications

Pine savannas of the southeastern United States evolved with frequent low-intensity wildfires. Today, land managers use prescribed fires to restore this ecological process while also controlling vegetative fuel accumulation. Given the ubiquitous application of this management tool, studies should consider impacts on target and nontarget taxa in these systems. During fires, animal populations persist in the landscape when individuals emigrate to unburned areas or seek refugia within the burn zone; otherwise, they experience local extirpation. We examined the effect of prescribed fires on a pine flatwoods specialist frog, the pinewoods treefrog Dryophytes femoralis, in a frequently burned pine landscape. …

Synthpop: A New Framework For Synthetic Milky Way Population Generation, Jonas Klüter, Macy J. Huston, Abigail Aronica, Samson A. Johnson, Matthew T. Penny, Marz Newman, Farzaneh Zohrabi, Alison L. Crisp, Allison Chevis

Faculty Publications

We present SynthPop, a new open source, modular population synthesis Galactic modeling software to simulate catalogs of Milky Way stars along any sightline outward from the Sun. Motivated by a lack of flexibility in existing Galactic models, SynthPop is coded entirely in python, can be run standalone or as an imported module, and is configured by json files that allow different model components to be switched out as desired. We describe the modular code structure, how the population generation process runs, and how to use the code. We also present model validation testing and known inaccuracies and present an example …

Climatologist Mann's Defamation Suit Victory: Can It Resolve The Crisis Of Expertise, David S. Caudill

Faculty Publications

When a jury awarded one million dollars in punitive damages to climatologist Michael Mann, in his defamation suit against writer Mark Steyn (who accused Mann of scientific fraud), it was newsworthy, even surprising, because opinions regarding scientific matters are rarely actionable. And yet it was not seen as a groundbreaking event in terms of legal doctrine, since the outcome was easily justifiable— Steyn’s accusation was provably false. However, even if the Constitutional contours of defamation law did not change, the Mann verdict has far-reaching implications for a major contemporary social phenomenon, namely the so-called crisis of expertise, a term identifying …

Stomach Content And Stable Isotope Analysis Of Invasive Lionfish (Pterois Volitans) In The Florida Keys, Emily E. Shallow, Cassandra N. Glaspie, Michael J. Polito, Mitchell S. Lovell

Faculty Publications

The invasive red lionfish, Pterois volitans, plays a unique role in seagrass and reef ecosystems, where it functions as a top predator and competitor for both food and shelter. Given the ubiquitous distribution of lionfish in the Gulf of Mexico and Caribbean basins, their species provides an excellent opportunity to understand how an invasive predator's diet and primary energy pathways change as a function of size and habitat type. To investigate these patterns, we studied lionfish from a mosaic of deep reef, shallow patch reef, and seagrass bed habitats in the Florida Keys using stomach contents and stable isotope analysis …

How Ai Can Help Mediators Say What They Really Mean, John Lande

Faculty Publications

This article critiques the widespread use of the terms “facilitative” and “evaluative” to describe mediation techniques. Despite their popularity in scholarship and practice, these labels are inconsistently defined, frequently misunderstood, and fundamentally flawed. Drawing on a survey of mediation experts, the article documents significant confusion about how professionals interpret these terms – and how they think that others interpret them. It builds on Leonard Riskin’s critique of the facilitative-evaluative framework, which shows that the language not only oversimplifies complex processes but also risks confusing parties and undermining informed decision-making.

As an alternative, the article proposes a behavioral vocabulary that reflects …

Perceived Adherence-Related Barriers For Youth Living With Hiv In The Southern United States, Kate Weaver, Sarah J. Miller, Sayward Harrison

Echo Chambers and Information Cocoons have become the subject of a multifaceted academic debate – ranging from the proper conceptualization and delineation of related concepts, to questions about their prevalence and uniqueness in the online environment, to arguments about their societal impact and the role of digital technologies. This study presents a systematic literature review that analyzes the existing research to synthesize relevant findings and build the missing foundations of these phenomena. This study follows a hermeneutic analytical approach to the literature to clarify and model the distinction between information cocoons and echo chambers. Furthermore, we summarize the selected literature …

X-Ray Polarimetric Observations Of The Western Hotspot Of Pictor A, Stefano Tugliani, Francesco Massaro, Michela Negro, Raffaella Bonino, Nicolò Cibrario, Luca Latronico, Simone Maldera, Alessandro Paggi, Andrea Tramacere, Eileen T. Meyer, Ioannis Liodakis, Herman L. Marshall, Eric S. Perlman

Faculty Publications

We present the results of the analysis of a ∼2 Msec spectropolarimetric observation of the western hotspot (WHS) of the radio galaxy Pictor A. This is the brightest extragalactic radio source that allows us to carry out spatially resolved observations using the Imaging X-ray Polarimetry Explorer (IXPE) because its WHS is located at ∼250″ from the radio core. The Pictor A WHS can be detected with IXPE as a pointlike source, with very low contamination from the nuclear emission, and it is extremely polarized at both radio and optical frequencies, where its emission is well described as synchrotron radiation. We …

Our understanding of the γ-ray sky has improved dramatically in the past decade, however, the unresolved γ-ray background (UGRB) still has a potential wealth of information about the faintest γ-ray sources pervading the Universe. Statistical cross-correlations with tracers of cosmic structure can indirectly identify the populations that most characterize the γ-ray background. In this study, we analyze the angular correlation between the γ-ray background and the matter distribution in the Universe as traced by gravitational lensing, leveraging more than a decade of observations from the Fermi-Large Area Telescope (LAT) and 3 years of data from the Dark Energy Survey (DES). …

We report on IXPE and NuSTAR observations beginning 40 days after the 2024 outburst onset of magnetar 1E 1841−045, marking the first IXPE observation of a magnetar in an enhanced state. Our spectropolarimetric analysis indicates that both a blackbody (BB) plus double power-law (PL) and a double blackbody plus power-law spectral model fit the phase-averaged intensity data well, with a hard PL tail (Γ = 1.19 and 1.35, respectively) dominating above ≈5 keV. For the former model, we find the soft PL (the dominant component at soft energies) exhibits a polarization degree (PD) of ≈30% while the hard PL displays …

Quantum Classical Algorithm For The Study Of Phase Transitions In The Hubbard Model Via Dynamical Mean-Field Theory, Anshumitra Baul, Herbert Fotso, Hanna Terletska, Ka Ming Tam, Juana Moreno

Faculty Publications

Modeling many-body quantum systems is widely regarded as one of the most promising applications for near-term noisy quantum computers. However, in the near term, system size limitation will remain a severe barrier for applications in materials science or strongly correlated systems. A promising avenue of research is to combine many-body physics with machine learning for the classification of distinct phases. We present a workflow that synergizes quantum computing, many-body theory, and quantum machine learning (QML) for studying strongly correlated systems. In particular, it can capture a putative quantum phase transition of the stereotypical strongly correlated system, the Hubbard model. Following …

‘I Can Kind Of Flow How I Want To Flow’: Motivations And Perceived Contrasts Of Providing Care In Home-Based Settings, Erin Harmeyer, Brittany Wittenberg Camp, Catherine Moon

Faculty Publications

The number of family child care (FCC) providers in the United States, or providers who are licensed, certified, or registered to provide care in their home, fell by nearly half between 2005 and 2017 (NCEQA, 2020a). This has implications for families who prefer FCC settings. Understanding providers’ motivations for starting their program may provide policymakers with information on how to better support providers drawn to this setting. Through interviews with 30 Black/bi-racial FCC providers, we found providers started their programs to support family/neighbors, to provide an alternative perceived to be safer than center-based programs, and to be in charge. In …
