Efficient Energy-Stable Discontinuous Galerkin Schemefor The Non-Isothermal Cahn–Hilliard–Navier–Stokestwo-Phase Fluid Flow System, Guang-An Zou, Meiting Wang, Kejia Pan, Yin Yang, Xiaofeng Yang

Faculty Publications

In this article, we propose a novel numerical framework for the non-isothermal Cahn–Hilliard–Navier–Stokes two-phase flow system, which couples the incompressible Navier–Stokes equations, the Cahn–Hilliard phase-field equation, and the heat transport equation to capture temperature-dependent two-phase flow dynamics. The pro-posed scheme achieves three major advances: (i) unconditional energy stability through a combined scalar auxiliary variable (SAV) and zero-energy-contribution (ZEC) approach, (ii) linearity and full decoupling of all variables while using a second-order temporal discretization, and (iii) efficient implementation via discontinuous Galerkin (DG) spa-tial discretization together with a second-order projection method for the Navier–Stokes equations. We rigorously prove the unconditional energy stability …

Rural–Urban Differences In Cognitive Outcomes Among Older Adults: The Roles Of Falls And Depressive Symptoms, Ayse Malatyali, Tom Cidav, Lisa A.K. Wiese, Jian Zou, Monique J. Brown Ph.D., Mph, Junfeng Ma, Breno S. Diniz, Ladda Thiamwong

Faculty Publications

Background: Older adults with Alzheimer’s Disease and Related Dementias (ADRD) experience a higher risk of falls. However, research lacks evidence on the effect of fall exposure on cognitive impairment and dementia. We investigated the association of falls and depressive symptoms with cognitive impairment and dementia in a nationally representative sample. Methods: We analyzed data from 6221 participants (age ≥ 65) in the Health and Retirement Study (HRS) from the 2018–2020 waves, using Multinomial logistic regression models. Measures included the HRS health status questionnaire, HRS cognition scale, and the Center for Epidemiological Studies Depression scale. Results: Prevalence of fall exposure across …

More Rights, More Danger For Police: An Experimental Look At How Messaging Shapes Public Views About Constitutional Carry, Hunter M. Boehme, Paige Vaughn

Faculty Publications

Constitutional carry (CC) laws, now enacted in 29 states, allow individuals to carry firearms openly without permits, yet little is known about public perceptions of these laws. This study employs a pre-registered survey experimental design to investigate whether varying support for CC laws by police leaders and politicians influences attitudes toward the laws and their perceived consequences. One-third of respondents supported CC laws, with most disagreeing that they will make communities safer. The majority of the sample felt these laws would increase personal liberty but also felt these laws would increase police danger. Oppositional messaging increased agreement that the laws …

Cognitive And Emotional Conflict Control Among Children Affected By Parental Hiv/Aids In China, Huihui Wang, Juan Liu, Danfeng Wen, Wan Zhao, Xiaoming Li Ph.D., Junfeng Zhao

Faculty Publications

Background: Children affected by parental HIV/AIDS constitute a particularly vulnerable population, often facing heightened risks in psychosocial adaptation due to family disruption, social stigma, and resource deprivation. However, the characteristics of their executive functions, particularly the core component of conflict monitoring, remain unclear.

Methods: The present study compared the performance of children affected by parental HIV/AIDS (n=32) to a control group (n=32) on a cognitive conflict and emotional conflict face-word Stroop task.

Results: The results of the cognitive Stroop task demonstrated that both groups showed better performance in congruent stimuli compared to incongruent stimuli (86.20% vs.67.30%; 568.43ms vs.586.04ms). In the …

Korean Words In The Oed: Race, Gender, And The Modern English Speaker, Elaine W. Chun

Faculty Publications

This article examines representations of the Modern English Speaker of Korean (MESK) in the Oxford English Dictionary (OED), as lexicographers listened to and documented the language of this figure over the past century. I show that, until the early twenty-first century, the most salient type of MESK was the Koreanist, a white, masculine expert on and translator of Korean, the language of a racial other. By contrast, more recent Korean entries, influenced by the global spread of hallyu, have invoked the Korea Fan, a figure that potentially unsettles longstanding ideologies of language, race, and gender. I …

Hybrid Cnn–Gru-Based Demand–Supply Forecasting To Enhance Sustainability In Renewable-Integrated Smart Grids, Süleyman Emre Eyimaya, Necmi Altin

Faculty Publications

The rapid integration of renewable energy sources in smart grids has introduced significant uncertainty in both power generation and consumption patterns, posing challenges to environmental, economic, and operational sustainability. Accurate short-term forecasting of energy demand and supply is essential for achieving optimal scheduling, grid stability, and resilient operation in renewable-integrated power systems. This study proposes a hybrid deep learning framework combining Convolutional Neural Networks (CNN) and Gated Recurrent Units (GRU) for intelligent joint demand–supply forecasting in smart grids. The model was developed and implemented in MATLAB using real-world datasets comprising electricity consumption, photovoltaic (PV) generation, temperature, and irradiance variables. Comparative …

Levers Of Default: Can The President Unilaterally Alter The Terms Of The National Debt?, Lev E. Breydo, Nathan B. Oman

Faculty Publications

The inviolability of America’s $30 trillion debt is a cornerstone of global markets and the U.S. economy. This Essay identifies a critical loophole: the President’s underappreciated power to dramatically change its legal structure—and argues that Congress should act to prevent a potential catastrophe.

The Essay details, for the first time in the literature, the arcane legal architecture underpinning America’s sovereign borrowings. Our analysis finds that although the President lacks authority to change the terms of outstanding debt retroactively, the President can accomplish similar goals by issuing new debt instruments that embed unprecedented powers. In surprisingly short order, a determined Executive …

Fuck: Public Opinion, Ian T. Adams, Marc Olson, Lois James, Brandon Tregle, Hunter M. Boehme

Faculty Publications

Profanity is common in everyday life, yet law enforcement often treats all swear words alike. Building on Adams (2024), we surveyed a large public sample (n = 2412) who evaluated profanity’s appropriateness, professionalism, impact on trust, and disciplinary deservedness across nine scenarios (n = 9874) varying in intent (positive, neutral, derogatory) and target (self/situation, colleague, public). Results aligned with prior research: any profanity aimed at the public, especially in a derogatory way, drew the strongest condemnation. Meanwhile, positive or neutral profanity toward oneself or colleagues was generally acceptable, though derogatory profanity at colleagues elicited moderate concern. Across the …

Demography And Dispersal Influence The Relationship Between Habitat Suitability And Population Density, Cleber Ten Caten, Tad Dallas

Faculty Publications

A central goal of ecology is to understand spatial patterns of species densities. Habitat suitability estimates from species distribution models (SDMs) could be used to represent species density and overcome the scarcity of density data. However, there is mixed evidence that habitat suitability is a reliable descriptor of density, and it is suggested that local dynamics affect the relationship between habitat suitability and density. We simulated population dynamics for 200 virtual species considering different combinations of factors (demographic stochasticity, dispersal, and intraspecific competition) that affect population sizes and SDMs were trained using different sets of environmental predictors to evaluate when …

Dynamic Magnetic Null Behavior In Planar Ion Diodes: Particle-In-Cell Analysis Of Field Oscillations And Ion Beam Dynamics, Jesse C. Foster, Stephen B. Swanekamp, Paul F. Ottinger

Faculty Publications

Particle-in-cell simulations of a 1.75 MV, 375 kA, and 50 ns planar pinched-beam diode reveal that the strongest gigahertz-frequency oscillations in electric field and ion current arise from the dynamic motion of the magnetic null near the anode tip. These oscillations, which appear when the ion transit time becomes comparable to the local field-variation timescale, periodically expand the effective anode–cathode gap and generate bursts of over-accelerated ions. The resulting ion energy spectrum broadens substantially near the null while maintaining excellent beam uniformity along the anode. The simulations, therefore, demonstrate a direct physical linkage between ion transit time instability and magnetic …

Rewired: Reconceptualizing Legal Services For The Ai Age, Lev E. Breydo

Faculty Publications

The legal profession is at a crossroads, caught between intensifying fears of AI-driven displacement and a generational opportunity for transformation. This Article provides a practical framework for navigating the shifting terrain.

Situating legal innovation within a multi-century arc of technological change, the Article draws on management and strategy scholarship to develop two core organizing models: the Legal Services Value Chain and the Innovation Frontier. The value chain disaggregates the lifecycle of a legal matter into five distinct nodes of activity, providing a map for subsequent analyses

Building on that foundation, the Innovation Frontier traces LegalTech’s evolution from 2000s-vintage e-discovery to …

Disciplining Mechanisms: Governing Data Markets With Competition And Regulation, Peter Ormerod

Faculty Publications

The past decade has witnessed conceptual renewals in both competition law and information privacy law. These regulatory movements—Neo-Brandeis antitrust and structural data governance—share the objective of recalibrating the balance of power between individuals and the massive data-processing firms that now dominate modern life.

Despite their common ends, policy interventions drawn from these schools of thought can work at cross purposes: competitive pressure can induce data exploitation, and privacy rules tend to benefit the largest firms.

This Essay exposes the friction in their relationship and offers guidance on how to mediate their tension. Competition policy alone will prove ineffective at indirectly …

Online Age Gating: An Interdisciplinary Evaluation, Noah Apthorpe, Brett Frischmann, Yan Shvartzshnaider

Faculty Publications

The recent surge in regulation seeking to establish age-based governance online is part of a decades-long attempt to establish online zoning. It is driven by active development of technologies to estimate or verify user age based on various characteristics of users, their credentials, or their activities. However, these developments have heightened prevailing concerns that online age gating technology will inevitably be abused and misused to cause a variety of privacy harms and rights infringements. This paper examines this ongoing debate by bridging technical and legal scholarship to explore the current state of online age-based governance. We discuss the current legal …

Post-Fire Inspection, Material Testing, Repair, And Field Load Testing Of A Full-Scale Concrete Box Girder Bridge: Delta Bridge Case Study, Ahmed S. Eisa, Hilal Hassan, Mohamed A. Badran, Ayman El-Zohairy

Faculty Publications

Bridges are critical components of transportation networks, and fire accidents can significantly impair their structural integrity, leading to safety risks and major economic losses. This study presents a comprehensive inspection, materials testing, repair, and field load testing program for a full-scale concrete box girder bridge (Delta Bridge, Alexandria, Egypt) following a fire exposure on two spans. A total of 28 concrete core samples were extracted and tested, revealing average compressive strengths of 48.50 MPa (slab), 53.90 MPa (web), and 45.88 MPa (columns), representing moderate reductions of approximately 8.5%, 7.9%, and 10.8%, respectively, relative to the original in situ concrete strength …

Survival On Image Regression With Application To Partially Functional Distributional Representation Of Physical Activity, Rahul Ghosal, Sunwoo Emma Cho, Marcos Matabuena

Faculty Publications

Technological advancements in wearable devices and medical imaging often lead to high-dimensional physiological signals in the form of images or surfaces. To address these data structures, we develop a novel survival on image regression model with a specific focus on partially functional distributional representation of wearable data. The existing approaches for functional data and survival outcomes have been primarily developed for uni-dimensional functional predictors. Drawing on recent developments in distributional data analysis, we model temporally varying distributional patterns of physical activity (PA) as a partially functional distributional predictor within a semiparametric Cox model framework. We use tensor product splines to …

Transformative Technology And Shortening The Statute Of Limitations Applicable To Taxpayers, Jay A. Soled, Leslie Book

Faculty Publications

When it comes to submitting tax returns and paying taxes, most taxpayers understand the nature of their civic duties and do so dutifully, if not willingly. However, many taxpayers fail to grasp why the IRS has such an elongated time period—namely, three years— to audit their tax returns and propose an assessment. Indeed, when the IRS exercises its oversight authority, records may no longer be available, and memories may be dulled.

Since the original institution of the three-year tax assessment limitations period nearly a century ago, tremendous technological strides have been made. Indeed, over ninety percent of income tax returns …

Integrating Future Factory-To-Factory (F2f) Manufacturing Through System Of Systems Engineering (Sose): A Framework For Capability Beyond Constituent Systems, Polinpapilinho F. Katina, Hengtao Tang Ph.D., Anouar Hallioui

Faculty Publications

System of Systems Engineering (SoSE) is an emerging discipline focused on the design, integration, and evolution of metasystems—composed of multiple autonomous yet interdependent systems. These systems of systems (SoS) offer capabilities that exceed those of any individual constituent systems by enabling synergistic coordination, interoperability, and dynamic adaptation across diverse operational contexts. This study pursued three primary objectives: (i) to examine the role of integration in enabling emergent capabilities beyond those of individual systems, (ii) to explore SoSE as a framework for orchestrating Future Factory-to-Factory (F2F) Manufacturing, and (iii) to assess the implications of SoSE to address volatile, uncertain, complex, and …

Us Federal Budgets And Federal Employee Job Satisfaction, Nathan Favero, Carla Flink, Tingli Qu

Faculty Publications

Researchers have long studied how organizational budgets relate to performance, but how do employees themselves experience the effects of budgetary decisions? Given widespread attention to political dysfunction in US federal budgeting, conventional wisdom holds that employees are negatively affected by budgetary uncertainty (volatility, delays, and stop-gap measures). We test how budget size and uncertainty are associated with US federal employee attitudes using survey and archival data from 2005 to 2020. Results provide some evidence that employee job satisfaction improves with enhanced funds, but there is little to no support for the notion that budgetary uncertainty influences federal employees' job satisfaction.

Structural And Mechanical Properties Facilitate Shock Wave Damping By Helmet-Like Orbital Hoods In Snapping Shrimp, Mia Kazel, Rebekah E. Cammack, Alexandra C.N. Kingston, Ahmed A. Alshareef, Tarek Shazly, Daniel Isaac Speiser

Faculty Publications

Snapping shrimp damp the shock waves they produce and use as weapons with a helmet-like structure termed the orbital hood. Here, we ask how structural and material properties contribute to shock wave damping by orbital hoods in Alpheus heterochaelis. Using tensile mechanical testing, we find orbital hoods are approximately half as stiff as carapace and have twice the capacity for viscous energy dissipation. Microstructural features probably contribute to tissue-specific mechanical properties: the endocuticles of orbital hoods have almost twice as many lamellae as those of carapaces despite being half as thick, suggesting a mechanism for enhanced material mobility underlying …

Equal Chances Or Fewer Victims? Moral Judgments In Autonomous Vehicle Dilemmas, Alexander Matros, Eren Bilen, Leonid Matros

Faculty Publications

We examine the moral dilemma of how autonomous vehicles (AVs) should be programmed to act in unavoidable crash scenarios involving trade-offs between saving one life and saving many. We report results from three experimental studies that investigate individuals’ preferences over alternative AV decision rules in stylized crash scenarios. Across designs, we find robust support for a probabilistic decision rule that assigns passengers and pedestrians equal ex ante chances of survival (a 50:50 rule). This preference persists across different framings and remains salient even when additional probabilistic options are introduced.

Construction Project Performance Research: A Bibliometric, Scientometric, And Qualitative Review (1989–2023), Abdelnaser Abdelhameed, Mohamed S. Yamany, Ahmed Abdelaty, Emad Elbeltagi

Faculty Publications

Despite the significant increase in publications on construction project performance (CPP), there is a deficiency of research that rigorously assesses and synthesizes previous studies to delineate the field’s development, themes, and research gaps. This article employs quantitative and qualitative methodologies to critically evaluate studies on CPP published over the last three decades and indexed in the Scopus database. The quantitative approach includes bibliometric searches and scientometric analyses to assess the extent of research interest and achievements. The qualitative methodology aims to conduct thorough content analysis to classify existing material based on prevalent themes. The results demonstrate an exponential growth of …

Nanomedicine Meets Immunotherapy: Transforming Chimeric Antigen Receptor T Cell Treatment For Solid Tumors, Stephen O'Rourke, Nuo Xu, Hongjun Wang, Hexin Chen

Faculty Publications

The emergence of effective immunotherapies has drastically revolutionized clinical management of many cancer types. Among them, chimeric antigen receptor (CAR)-T cell therapy (CTT), as a groundbreaking approach, has been considered as a “living drug,” displaying unprecedented clinical outcomes with hematological malignancies, including B cell leukemia and lymphomas, and multiple myeloma. Despite the high remission rates and improved survival achieved with hematological cancers, the effectiveness of CTT in solid tumors remains largely unsatisfactory. The efficacy of CTT in solid tumors is significantly challenged by multiple factors, including tumor-antigen heterogeneity, limited T cell trafficking and infiltration, a highly immunosuppressive tumor microenvironment, and …

The Brady Materiality Standard, Brandon L. Garrett, Adam M. Gershowitz

Faculty Publications

The Brady doctrine requires prosecutors to disclose all favorable and material evidence to the defense. To effectuate that rule, the U.S. Supreme Court has defined materiality as a “reasonable probability” that the evidence would have affected the outcome at trial. But apart from that definition, the Court has resisted offering any further guidance to lower courts. While far too little is known about how Brady materiality claims are actually adjudicated, there is strong evidence that courts often reject Brady claims involving withheld evidence on the grounds that the evidence was not significant enough to be material.

To examine how Brady …

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. …

“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 …
