Online Cyber-Physical Neural Network Model For Real-Time Hybrid Simulation, Faisal Nissar Malik, Liang Cao, James Ricles, Austin Downey

Faculty Publications

Real-time hybrid simulation (RTHS) is an experimental testing methodology that divides a structural system into an analyticaland an experimental substructure. The analytical substructure is modeled numerically, and the experimental substructure ismodeled physically in the laboratory. The two substructures are kinematically linked together at their interface degrees of freedom,and the coupled equations of motion are solved in real-time to obtain the response of the complete system. A key challenge inapplying RTHS to large or complex structures is the limited availability of physical devices, which makes it difficult to representall required experimental components simultaneously. The present study addresses this challenge by introducing …

A Comprehensive Assessment And Benchmark Studyof Large Atomistic Foundation Models For Phonons, Md Zaibul Anam, Ogheneyoma Aghoghovbia, Mohammed Al-Fahdi, Lingyu Kong, Victor Fung, Ming Hu

Faculty Publications

The rapid development of universal machine learning potentials (uMLPs) has enabled efficient, accurate predictions of diverse material properties across broad chemical spaces. While their capability for modeling phonon properties is emerging, systematic benchmarking across chemically diverse systems remains limited. We evaluate six recent uMLPs—EquiformerV2, MatterSim, MACE, and CHGNet—on 2429 crystalline materials from the Open Quantum Materials Database. Models were used to compute atomic forces in displaced supercells, derive interatomic force constants (IFCs), and predict phonon properties including lattice thermal conductivity (LTC), compared with density functional theory and experimental data. The EquiformerV2 pretrained model trained on the OMat24 dataset exhibits strong …

College For All And The Postsecondary Experiences Of Rural First-Generation College Students: Patterns Of Alignment With A Predominant Master Narrative, Andrew D. Coppens, Sarah Jusseaume, Jayson O. Seaman, Cindy L. Hartman, Erin H. Sharp

Faculty Publications

The aim of this study was to understand the experiences of rural, first-generation college (RFGC) students in relation to dominant culturally normative expectations about postsecondary educational and workforce trajectories. The study adopted patterns of engagement with a master narrative as both a conceptual framework and unit of analysis, examining both biography and cultural ecologies as well as highlighting agency in the lives and choices of study participants. Evidence is drawn from 4 in-depth narrative interviews with each of 14 RFGC students, conducted both at school and students’ homes, from rural and small-town communities. Results show that a master narrative of …

Using Serial Open Circuit Potentiometry To Study Ce And Gd Deposition In Molten Licl-Kcl Eutectic, Ranon G. Fuller, Guy L. Fredrickson, Devin Rappleye

Faculty Publications

The ability to electrochemically separate individual species in a pyrochemical reprocessing salt relies on first being able to detect a separation in their reaction potentials. This requires the ability to measure reaction potentials with extreme precision. In this work, we introduce a novel technique called serial open circuit potentiometry (SOCP) and demonstrate its effectiveness at precisely measuring metal deposition reaction potentials. SOCP has several advantages over traditional open circuit potentiometry, including its abilities to quantify the error of measured equilibrium potentials by averaging many individual OCP measurements, determine overpotential deposition nucleation potentials to instrument precision, and simultaneously determine the nucleation …

Moving Beyond Traditional Legal Scholarship Impact Rankings, John Cannan

Faculty Publications

Legal academia is likely stuck with law faculty scholarly impact rankings—that is, using citation counts to judge a law faculty’s reputation and influence. But why can’t we produce better, more useful studies? Current rankings rely on outdated methods. Moreover, these rankings—touted by their creators as objective—suffer from long-standing flaws. They are also grounded in limited understandings of legal citations as sources of information. This paper calls on law librarians to advance legal citation research by adopting methodologies from other information sciences and developing legal citation taxonomies and theories.

Localizing Public Order, Brenner M. Fissell

Faculty Publications

Public order offenses—public intoxication, sleeping outside, etc.—seem trivial, but they have enormous consequences for marginalized populations. These are the offenses that justify coercive police interactions, as well as entry into the procedural morass of the criminal legal system. Accordingly, these offenses have received extensive scholarly attention, with decades of research addressing their vagueness and their impact on urban communities of color. But no work has been done to survey how much of this conduct is criminalized and at what jurisdictional level—city or state.

This Article picks up that task, undertaking a comprehensive analysis of the criminal codes of the fifty …

Better Digital Contracts With Prosocial Friction-In-Design, Brett Frischmann, Moshe Y. Vardi

Faculty Publications

Contract law is supposed to enable people to reach genuine agreements and cooperate. If this ideal was ever a reality, the rise of mass market contracts and boil­erplate rendered it pure fiction. Modern consumer contracts are incomprehensible to most people. No one reads them anyway.

Digital contracting involves design features that amplify traditional boilerplate harms and create others. For example, digital contracting is too cheap; low marginal costs lead to overexpansion in scale and scope. To make matters worse, the loss of autonomy from repeat engagement with digital contracting systems is pernicious. People become increasingly predictable and programmable as digital …

Attribution As Architecture In The Digital Age, Laura A. Heymann

Faculty Publications

As technology changes, one thing remains constant: human creators seem to care about attribution, whether as creators or as audience members. Current U.S. law lacks the means for many creators to effectively address attributional interests, and experience has shown that top-down, imposed technological solutions can fail to gain the necessary buy-in and adoption. The best approach, examples suggest, is for platforms to think of attribution as part of the architecture of their systems, but to take their cues from user-developed, individualized solutions, which will not only be more responsive to user interests but also allow adaptation as interests change and …

Stories Of Racism And Resistance: A Narrative Analysis Of Stories Told In The Uk Windrush Generation And Descendants Of The Windrush Generation, Jessica Blumsom, Jacqui Scott, Emma Karwatzki, Aishath Nasheeda, David Hernandez-Saca, Alyson Malach, Glenda Andrew

Faculty Publications

The Windrush Generation (WG) and their descendants continue to experience adversity in the UK, including racism and the Windrush Scandal, with such adversities absent from psychological research literature. Intergenerational trauma is a psychological concept explaining that adverse experiences can be transmitted from one generation to impact subsequent generations. There has been limited consideration of the ongoing impact of adverse experiences that span multiple generations, such as experiences of racism within Western Europe. This paper utilised a narrative research design to study the narratives of members of the WG and those of their descendants in the UK. Eight expert by experience …

Land Struggles, Resistance, And Mutual Protection Along The Colorado-New Mexico Border: The Sacred Right Of Self-Preservation, José A. Rivera Ph.D

Faculty Publications

Mutual protection societies proliferated in the American Southwest during a period of rapid social change, 1870-1930, coincident with significant changes in the region’s political economy and increased competition for land and water resources. To resist encroachment and protect their natural resources, hispano communities in Colorado and New Mexico organized mutual benefit and protective associations known as mutualistas, with a large number concentrated in the San Luis Valley of Colorado as well as in many rural counties of northcentral New Mexico. The Costilla Valley of New Mexico is a prototypical hispano settlement initially established as part of the expansive Sangre …

Ncti Is The New Gilti, And States Should Still Conform, David Gamage, Darien Shanske

Faculty Publications

This essay continues our series on corporate profit shifting by analyzing how states should respond to the federal One Big Beautiful Bill Act, which transformed GILTI into the new Net Controlled Foreign Corporation Tested Income (NCTI) regime. We argue that states should conform to this new federal provision as a reasonable and legally sound approach to combatting the persistent profit shifting that erodes state tax bases. The 60 percent inclusion rate for NCTI effectively serves as a practical, "rough justice" estimate of income that was economically generated domestically but improperly shifted offshore — an estimate supported by empirical research. We …

On Good Terms: Pathways To Decolonizing Science-Appropriated Indigenous Terminologies In Arctic Research, Stanislav Saas Ksenofontov, Vera Kuklina, Alexander Kholodov, Andrey Petrov

Faculty Publications

Many western scientific disciplines adopted Indigenous Knowledge and terminology without deference to or understanding of the original meanings and values attached to Indigenous terms and concepts. This form of scientific appropriation has become a serious barrier to efforts of decolonizing Arctic research. The notion of Alaas is an example of such appropriation by the western science-based system of Indigenous knowledge about human–nature relations. This paper aims to discuss the term Alaas as it is conceptualized in both western science and Indigenous knowledge. The paper will explore the development of “alas” as an international permafrost science term and Alaas as an …

A Test Of The Abundant-Center Hypothesis For Stream Fishes, Matthew L.W. Zink, Brandon K. Peoples, Julian D. Olden, Lily M. Thompson, William K. Annis, Stephen R. Midway

Faculty Publications

The abundant-center hypothesis (ACH) provides a conceptual model for predicting range-wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported mixed support. Moreover, none of these models consider the possibility of multiple geographic areas of elevated abundance (which we refer to as ‘abundant cores'). Naturally dispersal limited species may exhibit multiple abundant cores, requiring refinement of the ACH. We used fish species abundances from 29 206 community monitoring surveys and weighted geospatial kernel …

Root Exudates: The Rhizospheric Frontier For Advancing Sustainable Plant Protection, Muhammad Rahil Afzal, Misbah Naz, Youbo Yu, Lisha Yan, Peiyi Wang, Janaki Mohotti, Gefei Hao, Jing-Jiang Zhou, Zhou Chen, Libo Zhang, Qian Wang

Faculty Publications

Root exudates (REs), a diverse array of bioactive metabolites secreted by plant roots in response to environmental stimuli, serve as key mediators of rhizosphere ecology and plant defense responses, offering a promising avenue for sustainable pest management and eco-friendly plant protection. While earlier reviews primarily focus on root exudates in the context of general rhizosphere dynamics and plant-microbial interactions, critical knowledge gaps persist in REs-plant-pest tripartite interactions, the mechanistic basis of REs-mediated plant defense, and their practical integration with integrated pest management (IPM) frameworks. This review provides a synthesis of the latest literature on the biochemical diversity and functions of …

Wind Turbine Rotor Design Using High-Fidelity Aerostructural Optimization, Marco Mangano, Sicheng He, Yingqian Liao, Denis-Gabriel Caprace, Andrew Ning, Joaquim R. R. A. Martins

Faculty Publications

Large wind turbines yield more energy but demand careful aeroelastic blade design. Coupled multiphysics design strategies can reduce wind energy costs exploiting fluid-structure interactions. This work presents the first high-fidelity aerostructural optimization study of a large wind turbine rotor.We use blade-resolved fluid dynamics and structural solvers in a monolithic gradient-based optimization framework to explore steady-state torque and blade mass trade-offs. The coupled-adjoint approach computes gradients efficiently, enabling the optimization of over 100 structural and geometric parameters simultaneously. Our optimization study modifies a DTU 10 MW benchmark with a simplified structure and isotropic material properties. The tightly coupled optimizations increase torque …

Categorial Declinations & Democracy, Brenner M. Fissell

Faculty Publications

The most contentious action taken by reform prosecutors has been the issuance of categorical declination policies. Opponents decry this as bureaucratic nullification of democratically enacted offenses, while the prosecutors themselves counter that they are responding to the will of their local electorate. Democracy claims, it appears, have taken center stage in this debate, and they are deployed by both sides. How should we think about democracy and categorical declinations? The most comprehensive scholarly work on this subject is a 2021 article by Professor Kerrel Murray. In this essay, I hope to continue the work begun by Murray, offering additional insights …

Against Activist Cooperation Agreements, Jennifer O'Hare

Faculty Publications

Shareholder activism is at record levels. In a typical campaign, the activist threatens to launch a proxy fight unless the board of directors agrees to take certain actions to increase shareholder value, such as selling off company assets or replacing the CEO. Increasingly, however, there are no proxy fights. Instead, the activist and the board, behind closed doors, quickly agree to settle. The activist withdraws the proxy fight threat, and, in return, the board appoints individuals designated by the activist to sit on the company board. This "Cooperation Agreement" allows the incumbent di- rectors to keep their positions and allows …

Faculty Publications

Recent advances in large language models and retrieval-augmented generation, a method that enhances language models by integrating retrieved external documents, have created opportunities to deploy AI in secure, offline environments. This study explores the feasibility of using locally hosted, open-weight large language models with integrated retrieval-augmented generation capabilities on CPU-only hardware for tasks such as question answering and summarization. The evaluation reflects typical constraints in environments like government offices, where internet access and GPU acceleration may be restricted. Four models were tested using LocalGPT, a privacy-focused retrieval-augmented generation framework, on two consumer-grade systems: a laptop and a workstation. A technical …

The Complexity Of Promoting Physical Activity In English State Primary Schools: An In-Depth Qualitative Analysis Of The Role Of Social Context, Robert Walker, Danielle House, Alice Porter, Ruth Salway, Simona Kent-Saisch, Michael Beets Ph.D., David Revalds Lubans, Frank De Vocht, Russell Jago

Faculty Publications

Background

Primary schools present an opportunity to equitably promote physical activity. To date, school-based interventions have had limited success. Contextual differences between schools could be a key factor that contributes to this lack of impact. However, the elements that constitute a school’s social context (i.e. the organisational, political, cultural, and sociodemographic characteristics) and how they might impact on primary school physical activity are unclear. The aims of this study were to conduct an in-depth qualitative analysis of state primary school social context related to physical activity and, using this analysis, provide recommendations for policy and practice.

Methods

We conducted one-to-one …

Impact Of Retrieval Augmented Generation And Large Language Model Complexity On Undergraduate Exams Created And Taken By Ai Agents, Erick S. Tyndall, Colleen Gayheart, Alexandre Some, Joseph Genz, Torrey J. Wagner, Brent T. Langhals

Faculty Publications

The capabilities of large language models (LLMs) have advanced to the point where entire textbooks can be queried using retrieval-augmented generation (RAG), enabling AI to integrate external, up-to-date information into its responses. This study evaluates the ability of two OpenAI models, GPT-3.5 Turbo and GPT-4 Turbo, to create and answer exam questions based on an undergraduate textbook. 14 exams were created with four true-false, four multiple-choice, and two short-answer questions derived from an open-source Pacific Studies textbook. Model performance was evaluated with and without access to the source material using text-similarity metrics such as ROUGE-1, cosine similarity, and word embeddings. …

Tort Liability For Failure To Age Gate: A Promising Regulatory Response To Digital Public Health Hazards, Matthew B. Lawrence, Brett Frischmann, Avi Sholkoff

Faculty Publications

Tort liability for failure to “age gate” is a promising legal response to the public health hazards of AI, social media, sports gambling, and other digital spaces. Tort liability for failure to “age gate” hinges liability for harms to minors on an app’s failure to take reasonable steps to prevent minors from gaining access or otherwise to apply appropriate governance rules, such as privacy-protective default settings or ensuring genuine parental consent. While no one legal response is a panacea, tort liability for failure to age gate carries several distinctive advantages that make it a particularly promising option at this stage …

Working Group Report: Developing A Playbook Of Equitable Grading Practices, Stephen H. Edwards, David L. Largent, Ben Schafer, Debarati Basu, Amy Csizmar Dalal, Dan Garcia, Brian Harrington, Kevin Lin, Dan S. Myers, Christian Roberson, Giulia Toti, Brett Wortzman

Faculty Publications

Traditional points-based grading can have negative impacts. As a result, many educators are experimenting with alternative grading practices that are more equitable for students. However, educators often face challenges in implementing equitable grading practices due to a lack of clear, practical descriptions of techniques and the fact that not all techniques are universally applicable. This working group addresses this problem using a three-pronged strategy: conducting a systematic literature review to gather documented techniques, compiling ''recipes'' or concrete descriptions of these techniques, and publishing them in an open-source, online ''playbook'' of equitable grading practices as a community resource for educators. This …

Bovine Neutrophil Migration, Cd11a/Cd18 Expression, And Cytokine Response To Co-Culture With Mammary Gland Endothelial Cells And Epithelial Cells, David J. Mcclenahan

Faculty Publications

Movement of leukocytes from the circulatory system into a site of inflammation is a highly complex process. The migration of neutrophils into the lumen of the mammary gland during mastitis is no exception. There is information about the involvement of bacterial-produced products during this process, but less is known regarding the role of host products. Two bovine cell lines, a primary mammary gland endothelial cell line and an immortalized bovine mammary gland epithelial cell line (Mac-T), along with freshly isolated bovine neutrophils, were used to study this further. The cell lines were grown on inserts and in wells of tissue-culture …

Pinch: Pipeline-Informed Noise Characterization In Ligo’S Third Observing Run, Zach Yarbrough, Andre Guimaraes, Prathamesh Joshi, Gabriela González, Andrew Valentini

Faculty Publications

We present a method to identify and categorize gravitational wave candidate triggers identified by matched filtering gravitational wave searches (pipelines) caused by transient noise (glitches) in gravitational wave detectors using support vector machine (SVM) classifiers. Our approach involves training SVM models on pipeline triggers which occur outside periods of excess noise to distinguish between triggers caused by random noise and those induced by glitches. This method is applied independently to the triggers produced by the GstLAL search pipeline on data from the laser interferometer gravitational-wave observatory Hanford and Livingston observatories during the second half of the O3 observing run. The …

Faculty Publications

This study seeks to investigate historical drinking water contamination events that reported by news media to find the key determinants of their outcomes, including the duration and economic cost, and to quantitatively describe the characteristics of past contamination events. ProQuest Global Newsstream and Regional Business News were used to identify an initial list of events and supplemented by additional search on specific information including the response actions, economic cost, and more. These events were analyzed using descriptive statistics, correlation analysis, and regression modeling. Smaller community water systems were found to be more frequently impacted by contamination events. Use restrictions, except …

“I Laughed Along For Years But Hated It Inside:” Understanding Nuance In Peer Teasing Experiences Using A Thematic Analysis, Naomi C.Z. Andrews, Molly Dawes Ph.D.

Faculty Publications

Introduction

Peer teasing is ubiquitous, yet ambiguous in nature. Despite recent attempts to delineate and clarify differences in teasing experienced as playful versus harmful, there remains overlap and complexity in these interactions. In the current study, we present a conceptual model of teasing, which includes many nested features that dynamically interact within a teasing episode. Using this conceptual model to guide our work, the goal of the current study was to use qualitative inquiry to bring further conceptual clarity to the overlap between teasing that is experienced as playful versus harmful.

Method

Using semi-structured interviews, we asked university students ( …

Subtropical Marine Cloud Brightening Suppresses The El Niño–Southern Oscillation, C. Xing, S. Stevenson, J. Fasullo, C. Harrison, C. Chen, J. Wan, J. Coupe, C. Pfleger

Faculty Publications

Stratospheric aerosol injection (SAI) and marine cloud brightening (MCB) are two proposed methods of compensating for greenhouse gas-induced warming by reflecting incoming solar radiation. However, their effects on the El Niño–Southern Oscillation (ENSO), a critical mode of climate variability, are poorly understood. Here we use ensembles of climate model simulations to show that deploying MCB in the subtropical eastern Pacific dramatically reduces ENSO amplitude by approximately 61%, while SAI has a negligible impact. MCB increases cloud albedo, which cools the subtropical eastern Pacific and triggers a loss of moist static energy. This cooling promotes atmospheric subsidence, dries the tropical Pacific, …

Rate Of Sea-Level Rise And Sediment Characteristics Modulate Deltaic River-Tide Interactions, Peter Bacopoulos, Celalettin E. Ozdemir, Matthew Hiatt

Faculty Publications

Due to sea-level rise, small river-dominated deltas (< 100 km²) are expected to become more exposed to tidal influences in the future. However, there remains a knowledge gap in the impending hydrodynamics of such deltas, particularly with the interactions between river and tidal flows. In addition to sea-level rise, river-tide interactions in these deltas depend on their morphology, which is influenced by the sand proportion in the particulate matter delivered by rivers. This study investigates river-tide interactions predicted for small deltas formed by different sand-to-mud ratios under various sea-level rise scenarios. Delta morphologies were generated using reduced-order complexity model (DeltaRCM), …

Louisiana's Ten Commandments Statute: With Litigation Updates From Arkansas And Texas, Carl H. Esbeck

Faculty Publications

Legislators in conservative states are drawn to a belief that the Ten Commandments [“10/Cs”] underscore American’s moral, jurisprudential, and historical heritage. First the State of Louisiana, and thereafter Arkansas and Texas, enacted legislation requiring the posting of the 10/Cs in every public school and university classroom in the state. This quickly brought on legal challenges by students and their parents, along with a smattering of local clerics, together contending that these laws were unconstitutional, most prominently violations of the Establishment Clause. State attorney generals leaped to defend these statutes making the facial assertion that the 10/Cs are not so much …
