Influence Of Superhydrophobic Surface Microstructure On Transient Jet Impingement Cooling, D. Jacob Butterfield, Brian D. Iverson, Daniel Maynes, Julie Crockett

Faculty Publications

Water jet impingement is an effective method of rapidly cooling a surface, but heat transfer from the surface is highly dependent on the surface condition and properties. Here, the impact of a superhydrophobic (SH) surface on heat transfer to an impinging, axisymmetric, room-temperature water jet with Re=6 x 10³to 18 x 103 is explored. SH surfaces are created by etching thin silicon wafers to form different micropatterns (posts or holes). Surfaces are heated to between 200 and 320°C, and the local surface temperature is measured with a thermal camera. The time resolved heat transfer from the surface and …

Is History Precedent?, Allison Orr Larsen

Faculty Publications

It has been just over three years since the Supreme Court instructed lower courts to evaluate Second Amendment challenges by examining history and tradition. And it is no secret that the courts have struggled. This Article tackles a phenomenon that is born of that struggle. Overwhelmed by the task of evaluating historical claims, lower courts instead are turning to other judges as authorities on history. They are using what I call in this Article “historical precedents”—meaning language about history from an older decision that the subsequent judge then treats as authority, not as part of a legal rule but for …

Ceo Pay Differences Between Us And Non-Us Firms: A New Longitudinal Investigation, Ruiyuan (Ryan) Chen, Sadok El Ghoul, Omrane Guedhami, Feiyu Liu

Faculty Publications

Research Question/Issue

Public and academic debates typically portray US CEOs as exceptionally well paid. Yet, evidence on the existence and magnitude of a US CEO pay premium is mixed and dated. This study uses an expanded, longitudinal dataset to identify whether such a pay premium exists and explores potential differences across countries, time, and governance and institutional contexts.

Research Findings/Insights

Using a dataset of over 42,000 firm-year observations from 34 countries during 2001–2018, we document a persistent but heterogeneous US CEO pay premium. Compared with non-US peers, US CEOs receive 23% more total pay and 20% more equity-based compensation, on …

(Re)Individualizing Criminal Law, Itay Ravid

Faculty Publications

Criminal law purports to care about the individual culpability of those committing crimes. Individual mental states or defenses based on one’s beliefs are considered foundational to moral responsibility and criminal conviction. The expansion of algorithmic risk assessment tools in the criminal legal system, however, threatens these principles, changing the criminal law subject from an autonomous individual to merely a predicted object. This Article argues that risk assessment tools—now functioning as gatekeepers at both the entry and exit stages of the criminal process, from predictive policing to compassionate release eligibility—have shifted the criminal system away from its foundation in individual culpability. …

Patient-Specific Lumped-Parameter Model For Quantifying Vessel-Specific Remodeling And Predicting Right Ventricular Function In Pulmonary Hypertension, Christopher G. Lechuga, Amirreza Kachabi, Mitchel J. Colebank, Claudia E. Korcarz, Farhan Raza

Faculty Publications

Purpose: Pulmonary hypertension (PH) is a heterogeneous disease with patient-specific variability and vessel-specific remodeling, which eventually lead to right ventricular (RV) failure. The gold standard for RV assessment—pressure–volume (PV) loop acquisition—is invasive and limited to specialized settings. This study aims to develop a patient-specific lumped-parameter model that quantifies vessel-specific remodeling and simulates RV PV loops across PH phenotypes using routine clinical data.

Methods: A lumped-parameter model was calibrated using right heart catheterization and echocardiography data. Model agreement was assessed by R2 values for pressure and flow goodness-of-fit, and model-derived hemodynamic metrics were comparedwith clinical values. A dimensionality reduction approach was …

This study examines the impact of ski tourism on Colorado’s retail marijuana (RMJ) sales, leveraging county-level sales data and ski resort characteristics. Using a two-way fixed effects model, we analyze seasonal variations in RMJ sales across counties with differing ski resort acreages. Our findings indicate that ski resort counties experience significant increases in RMJ sales during peak ski months (December–March), with the most prominent effects observed in counties with the largest ski resorts. The largest ski resort county– Summit County– sees an estimated seasonal increase of $4.35 million in RMJ sales. We estimate the isolated extra-state ski tourism effects and …

“When And Where [We] Enter…”? Intersectional Ideologies And Experiences In African American Support For Lgbtq+ Communities, Monique L. Lyle, Todd Shaw

Faculty Publications

This article examines how intersectional ideologies and experiences of marginalization affect the extent to which African Americans support or oppose the marginalization of LGBTQ communities. We posit that awareness of the race-gender positionality of African American women, as well as the unique positionalities of other marginalized African American subgroups, is critical to understanding the conditions under which Black Americans embrace LGBTQ rights and communities. Using the Black respondent subsample of the 2016 Collaborative Multiracial Post-Election Study, we test the extent to which intersectional theories explain African American cross-group consciousness with LGBTQ persons and support for LGBTQ rights and communities. In …

Improving Lexicosemantic Impairments In Post-Stroke Aphasia Using Rtms Targeting The Right Anterior Temporal Lobe, Sophie Arheix-Parras, Sophia R. Moore, Rutvik H. Desai

Faculty Publications

Background/Objectives: Repetitive Transcranial Magnetic Stimulation (rTMS) can enhance post-stroke aphasia recovery. The right Inferior Frontal Gyrus is the most common target in rTMS studies for inhibitory stimulation. However, lexicosemantic processes involve a large brain network including the Anterior Temporal Lobe (ATL). We hypothesize that rTMS targeting the ATL will improve lexicosemantic impairments in people with post-stroke aphasia. Methods: In a Single-Case Experimental Design, three people with post-stroke aphasia with lexicosemantic impairments performed Picture and Auditory Naming and Semantic Decision tasks five times a week for one or two weeks to establish baseline scores. Then, each participant received continuous inhibitory Theta …

Police Staffing Shortages, Public Awareness, And Policy Preferences, Hunter M. Boehme, Joshua Mccrain, Scott M. Mourtgos, Brandon Tregle

Faculty Publications

Since the summer of 2020, police agencies across the United States have continued to experience police staffing shortages. The consequences of understaffed police agencies are well studied, but little is known about whether the public is aware of the staffing problem and its consequences for public safety and police behavior. This study presents a pre-registered factorial survey experiment to 3105 US adults, varying the information respondents see on the consequences of staffing shortages (e.g., public safety, police behavior) and the messenger of this information (e.g., police chief, mayor). Respondents are then asked about their levels of concern about police staffing, …

When Disasters Trigger Cyber Vulnerabilities: Mapping Physical-Digital Interdependencies In Critical Infrastructure Systems, Dikshya Panta, Sicheng Wang, Aditya Sapkota, Prakash Ranganathan

Faculty Publications

Critical infrastructure (CI) systems such as power, water, communications, and emergency services are increasingly exposed to compound risks in which natural disasters and cyber incidents interact and amplify one another. Traditional risk assessments often isolate physical and digital threats, overlooking the cascading dependencies that emerge when operational stress, emergency reconfiguration, and adversarial exploitation coincide. This study conducts a 2019–2025 scoping review and introduces a Geographic Information System (GIS) driven six-stage disaster cyber compounding framework that characterizes, maps, and operationalizes compound risk across interdependent CI sectors. The framework integrates a common operating picture, analytic situational understanding, exposure mapping, threat-fingerprint encoding, detection …

Effects Of Social Support Interventions On Medical Patient Survival: A Meta-Analysis Of Non-Randomized Clinical Trials, Ksenia Illinykh-Bair, Timothy B. Smith

Faculty Publications

Background: Prior research confirms that social support promotes resilience among medical patients with chronic illness. Beyond emotional benefits, research has increasingly shown the importance of social support on physical health outcomes. Therefore, identifying and evaluating interventions that increase social support among medical patients with chronic conditions is a priority for healthcare. Methods: This meta-analysis summarized data from 39,493 medical patients across 14 non-randomized trials that had been identified by a prior review of the survival benefits of social support interventions. Results: Across four studies reporting hazard ratio data, the results failed to reach statistical significance (HR = 2.10, 95% CI …

Statewide Sanctuary Policies And Female Homicide Rates, 2016–2021, Kaitlin M. Boyle, Sophia Shaiman, Veronica Valencia Gonzalez, Wendy Regoeczi

Faculty Publications

The current study examines whether state immigration enforcement policies, such as sanctuary policies that limit local police cooperation with federal immigration enforcement, are associated with female homicide rates in the United States (2016–2021). We examine crude female homicide rates from the National Violent Death Reporting System (N = 244 state-years), which we stratify by race and ethnicity (Hispanic of all races, non-Hispanic Black, and non-Hispanic White) and victim–suspect relationship (domestic vs. stranger homicide). State-years with policies that are more protective of immigrants were not associated with higher homicide rates for any group. Instead, state-years with these policies reported significantly lower …

Pdr-Stgcn: An Enhanced Stgcn With Multi-Scale Periodic Fusion And A Dynamic Relational Graph For Traffic Forecasting, Jie Hu, Bingbing Tang, Langsha Zhu, Yiting Li, Jianjun Hu, Guanci Yang

Faculty Publications

Accurate traffic flow prediction is a core component of intelligent transportation systems, supporting proactive traffic management, resource optimization, and sustainable urban mobility. However, urban traffic networks exhibit heterogeneous multi-scale periodic patterns and time-varying spatial interactions among road segments, which are not sufficiently captured by many existing spatio-temporal forecasting models. To address this limitation, this paper proposes PDR-STGCN (Periodicity-Aware Dynamic Relational Spatio-Temporal Graph Convolutional Network), an enhanced STGCN framework that jointly models multi-scale periodicity and dynamically evolving spatial dependencies for traffic flow prediction. Specifically, a periodicity-aware embedding module is designed to capture heterogeneous temporal cycles (e.g., daily and weekly patterns) and …

Fatigue Crack Length Estimation Using Acoustic Emissions Technique-Based Convolutional Neural Networks, Asaad Migot, Ahmed Saaudi, Roshan Joseph, Victor Giurgiutiu

Faculty Publications

Fatigue crack propagation is a critical failure mechanism in engineering structures, requiring meticulous monitoring for timely maintenance. This research introduces a deep learning framework for estimating fatigue fracture length in metallic plates through acoustic emission (AE) signals. AE waveforms recorded during crack growth are transformed into time-frequency images using the Choi–Williams distribution. First, a clustering system is developed to analyze the distribution of the AE image-based dataset. This system employs a CNN-based model to extract features from the input images. The AE dataset is then divided into three categories according to fatigue lengths using the K-means algorithm. Principal Component Analysis …

Proposed Methodology For Correcting Fourier-Transform Infrared Spectroscopy Field-Of-View Scene-Change Artifacts, Kody A. Wilson, Michael L. Dexter, Benjamin F. Akers, Anthony L. Franz

Faculty Publications

Fourier-transform spectrometers are widely used for spectral measurements. Changes in the field of view during measurement introduce oscillations into the measured spectra known as scene-change artifacts. Field-of-view changes also introduce uncertainty about which target the measured spectrum represents. Though scene-change artifacts are often present in dynamic data, their significance is disputed in the current literature. This work presents a theoretical framework and experimental validation for scene-change artifacts. Field-of-view changes introduce variable interferogram offsets, which standard processing techniques assume are constant. The error between the interferogram offset and its estimate is Fourier-transformed, yielding scene-change artifacts, often confused with noise, in the …

Faculty Publications

In recent years, hybrid organic–inorganic metal halides have been at the forefront of materials research. Typically, the functional (e.g., optoelectronic) properties of hybrid halides are derived from the inorganic structural part, whereas the organic structural units can add extra advantages in terms of stability, rigidity, and processability. Here, we report the design, synthesis, and characterization of two new hybrid materials in which the outstanding photophysical properties originate from the organic structural part. The new compounds, (C₁₅H16N)₂CdCl₄ and((Br)C₁₅H₁₅N)₂CdCl₄, have 2D layered Ruddlesden–Popper-type perovskite structures. These hybrids are blue-white …

Tuning Oxygen Reduction Kinetics In Lasrcoo4 With Strained Epitaxial Thin Films And Wrinkled Freestanding Membranes, Habib Rostaghi Chalaki, Ebenezer Sessi, Mohammad El Loubani, Dongkyu Lee

Faculty Publications

Sluggish oxygen reduction reaction (ORR) remains a critical barrier to advancing intermediate-temperature electrochemical energy devices. Here, we demonstrate that strain engineering in two platforms, epitaxial thin films and freestanding membranes, systematically tunes ORR kinetics in Ruddlesden-Popper LaSrCoO4. In epitaxial films, film thickness is varied to control in-plane tensile strain, whereas in freestanding membranes strain relaxation during the release step using water-soluble sacrificial layers produces flat or wrinkled architectures. Electrochemical impedance spectroscopy analysis reveals more than an order of magnitude increase in the oxygen surface exchange coefficient for tensile-strained films relative to relaxed films, together with a larger oxygen vacancy concentration. …

Molecular Survival Strategies Against Kidney Filtration: Implications For Therapeutic Protein Engineering, William Heaps, Anna Elise Packard, Kristina M. Mccammon, Tyler P. Green, Joseph P. Talley, Bradley C. Bundy, Dennis Della Corte

Faculty Publications

The glomerular filtration barrier poses a significant challenge for circulating proteins, with molecules below ~60–70 kDa facing rapid renal clearance. Endogenous proteins have evolved sophisticated evasion mechanisms including oligomerization, carrier binding, electrostatic repulsion, and FcRn-mediated recycling. Understanding these natural strategies provides blueprints for engineering therapeutic proteins with improved pharmacokinetics. This review examines how endogenous proteins resist filtration, evaluates their application in protein engineering, and discusses clinical translation including established technologies (PEGylation, Fc-fusion) and emerging strategies (albumin-binding domains, glycoengineering). We address critical challenges of balancing half-life extension with tissue penetration, biological activity, and immunogenicity—essential considerations for the rational design of next-generation …
