Examining Whether Method Of Suicide Exposure And Closeness To Decedent Relate To Firearm Storage Practices, Evan A. Albury, Jessica L. Gerner, David A. Jobes, Raymond P. Tucker

Faculty Publications

Introduction: One factor that can influence whether someone will engage in secure firearm storage is having a suicide exposure (SE). Daruwala et al. (2018) examined this and found that individuals with an SE, without considering perceived closeness, did not significantly differ from those who did not have an SE in their firearm storage practices. Thus, the present study aimed to replicate and extend the research of Daruwala et al. (2018) by examining if the method of suicide (by firearm or other means) and closeness of suicide decedent relate to secure firearm storage practices. Methods: 308 male firearm owners completed self-report …

Utilizing Machine Learning To Predict Host Stars And The Key Elemental Abundances Of Small Planets, Amílcar R. Torres-Quijano, Natalie R. Hinkel, Caleb H. Wheeler, Patrick A. Young, Luan Ghezzi, Augusto P. Baldo

Faculty Publications

Stars and their associated planets originate from the same cloud of gas and dust, making a star’s elemental composition a valuable indicator for indirectly studying planetary compositions. While the connection between a star’s iron (Fe) abundance and the presence of giant exoplanets is established, the relationship with small planets remains unclear. The elements Mg, Si, and Fe are important in forming small planets. Employing machine learning algorithms like XGBoost, trained on the abundances (e.g., the Hypatia Catalog) of known exoplanet-hosting stars (NASA Exoplanet Archive), allows us to determine significant “features” (abundances or molar ratios) that may indicate the presence of …

Exact Inference For Transformed Large-Scale Varying Coefficient Models With Applications, Tianyu Chen, Robert Habans, Thomas Douthat, Jenna Losh, Lida Chalangar Jalili Dehkharghani, Li Hsiang Lin

Faculty Publications

Studying migration patterns driven by extreme environmental events is crucial for building a sustainable society and stable economy. Motivated by a real dataset about human migrations, this paper develops a transformed varying coefficient model for origin and destination (OD) regression to elucidate the complex associations of migration patterns with spatio-temporal dependencies and socioeconomic factors. Existing studies often overlook the dynamic effects of these factors in OD regression. Furthermore, with the increasing ease of collecting OD data, the scale of current OD regression data is typically large, necessitating the development of methods for efficiently fitting large-scale migration data. We address the …

Do Analysts’ Gross Margin Forecasts Influence Manager's Decisions To Recognize Inventory Losses?, Nusrat Jahan, Padmakumar Sivadasan

Faculty Publications

Accounting standards require firms to write down their inventory when its market value (or net realizable value) drops below cost. Recognizing inventory write-downs decreases gross margins and increases scrutiny of managers’ inventory management practices. Further, it is difficult for market participants to assess inventory balances. Therefore, managers often delay recognizing inventory losses. Compared with other analysts, analysts who issue disaggregated gross margin (GM) forecasts evaluate a firm's inventories more closely, which should motivate managers to recognize expected inventory losses. Consistent with this prediction, managers’ likelihood of recognizing an expected inventory loss increases as more analysts provide GM forecasts. However, the …

The Proximity Effect And Critical Field Behavior Of Re/Al Bilayers, F. N. Womack, I. M. Ortega, S. K. Karna, D. Graf, P. W. Adams

Faculty Publications

We report the perpendicular critical field Hc2 properties of disordered Re-Al bilayers via magneto-transport measurements. The bilayers consisted of a d Re = 3 nm bottom layer of Re and an upper Al layer with thickness varying between dAl = 0 − 3 nm. We find that in this range of Al thicknesses, the bilayer transition temperature Tc increases with increasing Al thickness, although their monolayer counterparts have T c Re > T c Al . Furthermore, Hc2 of the bilayers has a local maximum at an Al coverage of 1.5 nm with a critical field that is 50% larger than …

Fast Dynamic Ejecta In Neutron Star Mergers, Stephan Rosswog, Nikhil Sarin, Ehud Nakar, Peter Diener

Faculty Publications

The ejection of neutron-rich matter is one of the most important consequences of a neutron star merger. While the bulk of the matter is ejected at fast, but non-relativistic velocities (∼ 0.2c), a small amount of mildly relativistic dynamic ejecta have been seen in a number of numerical simulations. Such ejecta can have far-reaching observational consequences ranging from the shock breakout burst of gamma-rays promptly after the merger, to an early (∼ 1 h post-merger) blue kilonova precursor signal, to synchrotron emission years after the merger (‘kilonova afterglow’). These all potentially carry the imprint of the binary system parameters and …

Polarization-Resolved Core Exciton Dynamics In Lif Using Attosecond Transient Absorption Spectroscopy, Kylie J. Gannan, Lauren B. Drescher, Rafael Quintero-Bermudez, Navdeep Rana, Chengye Huang, Kenneth Schafer, Mette B. Gaarde, Stephen R. Leone

Faculty Publications

The ability to control absorption by modifying the polarization of light presents an exciting opportunity to experimentally determine the orbital alignment of absorption features. Here, attosecond extreme ultraviolet (XUV) transient absorption spectroscopy is used to investigate the polarization dependence of core exciton dynamics in LiF thin films at the Li+K edge. XUV pulses excite electrons from the Li 1s core level into the conduction band, allowing for the formation of a p-orbital-like core exciton, aligned along the XUV light polarization axis. A sub-5 fs near-infrared (NIR) probe pulse then arrives at variable time delays, perturbing the XUV-excited states and allowing …

Resonant Propagation Of Extreme-Ultraviolet Pulses Through Strongly Driven High-Density Media, Yu He, Shuyuan Hu, Gergana D. Borisova, Yizhu Zhang, Marc Rebholz, Zuoye Liu, Mette B. Gaarde, Christian Ott, Thomas Pfeifer

Faculty Publications

We show that by combining strong-field dressing and resonant propagation of XUV pulses, the transition of absorption lines from their natural Lorentzian profiles through Fano and complex multipeak shapes all the way back to broadened near-Lorentzian profiles can be achieved, in the limit of optically thick samples. The final stage of this spectral modification can be understood in terms of a significant temporal stretching and delay of the resonant XUV pulse as it propagates through the dense gas, which alters the ultrafast absorption that is modified by the time-synchronized few-femtosecond laser pulse. We first demonstrate this concept in numerical calculations, …

Faculty Publications

Time-resolved second harmonic generation (SHG) microscopy is used to investigate the physicochemical interactions between positively charged, hydrophobic, drug-like molecules and the plasma membrane of human cells (nonsmall cell lung cancer, H596). In the present study, molecular adsorption and transport of the cationic molecules, malachite green (MG) and malachite green isothiocyanate (MGITC), are studied in real time in living H596 cells and in dead, fixed H596 cells. MGITC is shown to have stronger adsorption and more rapid transport kinetics as compared to MG due to increased dipole-dipole interactions. Additionally, MGITC is found to have faster adsorption and transport kinetics in living …

Faculty Publications

Herein, we examine pathway complexity in the supramolecular polymerization of a novel m-terphenyl bis-urea macrocycle. Designed to induce kinetically metastable states, the macrocycle‘s concentration-dependent aggregation was studied via 1H NMR and IR spectroscopy in THF and CHCl₃. Temperature-dependent UV-Vis spectroscopy in water/THF revealed a cooperative nucleation-growth mechanism, indicated by a shift in λmax to longer wavelengths upon cooling. Morphological studies using DLS, AFM, and SEM demonstrated fibrous aggregate formation. Thermal hysteresis observed in assembly-disassembly cycles indicated kinetically trapped species, with cooling governed by kinetic control and heating by thermodynamic processes. Deviations in ΔH values during cooling, compared to van′t …

Ultrasonic Spray Coating Of Carbon Fibers For Composite Cathodes In Structural Batteries, Thomas Burns, Liliana Delatte, Gabriela Roman-Martinez, Kyra Glassey, Paul Ziehl, Monirosadat Sadati, Ralph E. White, Paul T. Coman

Faculty Publications

Structural batteries, also known as “massless batteries”, integrate energy storage directly into load-bearing materials, offering a transformative alternative to traditional Li-ion batteries. Unlike conventional systems that serve only as energy storage devices, structural batteries replace passive structural components, reducing overall weight while providing mechanical reinforcement. However, achieving uniform and efficient coatings of active materials on carbon fibers remains a major challenge, limiting their scalability and electrochemical performance. This study investigates ultrasonic spray coating as a precise and scalable technique for fabricating composite cathodes in structural batteries. Using a computer-controlled ultrasonic nozzle, this method ensures uniform deposition with minimal material waste …

Real-time reactor power monitoring is critical for a variety of nuclear applications, spanning safety, security, operations, and maintenance. While machine learning methods have shown promise in monitoring reactor power levels, there is limited research on their efficacy in label-starved environments. The goal of this work is to assess the feasibility of classifying nuclear reactor power level using multisource data in scenarios with limited labels. Data were collected using low-resolution multisensors at four nuclear reactor facilities: two large research reactors and two TRIGA reactors. Within each pair, one reactor dataset served as the source and the other as the target in …

The Effects Of Snow Cover On The Dynamic Pressure Of Nuclear Detonation Blast Waves, Adam Card, Andrew W. Decker

Faculty Publications

Blast pressure is the primary military targeting metric for nuclear weapons. Any local conditions that affect blast pressure have the potential for altering nuclear plans, both from defensive and offensive standpoints. Understanding the impact of snow to the blast wave, therefore, provides a benefit both to military planners and to warfighters on the ground, for any operation occurring in arctic environments. No existing data provides a quantitative description of how snow on the ground affects a nuclear detonation blast wave passing over it. Similar blast waves passing over dust have experimentally proven to enhance blast pressure in a localized region.1 …

Analyzing Stability Of Estimates At Completion For Long Duration Development Efforts, Bradley Vuu, Jonathan D. Ritschel, Brandon M. Lucas, Edward D. White

Faculty Publications

Defense program managers utilize Earned Value Management (EVM) methodologies to measure, report, and predict the cost and schedule performance of their programs. Previous research conducted by Christensen (1996) and Kim et al. (2019) has shown varied results in the stability of EVM Estimates at Completion (EACs). Stability is defined as a 10% or less deviation from the final EAC at a specified percent completion point of the program. The Christensen (1996) and Kim et al. (2019) studies also noted that program-specific factors, such as phase, can impact the accuracy of EVM metrics. This study builds upon those works by assessing …
