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. …

Reformulation Of The Protein Databank For Real-Time Search Of Geometrical Attributes Of Protein Structures, Musa Azeem, Christopher Lee, Aaron Hein, Christopher Ott, Homayoun Valafar

Faculty Publications

Introduction:

In this study, we introduce the design and implementation of PDBMine, a large-scale, queryable platform for mining sequence-structure statistics from the Protein Data Bank (PDB). PDBMine enables rapid analysis of local conformational trends across proteins by extracting dihedral angles and sequence patterns at scale. In addition to the design and implementation of PDBMine, we also present results validating its ability to return structurally meaningful information.

Methods:

We first assess the accuracy of its dihedral angle distributions by comparing them to established Ramachandran space and verifying expected behaviors of residues such as glycine and proline. We then use PDBMine to …

A Comparison Of Modeled Daytime E Regions From E-Probed And Pyiri With Ionosonde Observations, Daniel J. Emmons, Cornelius C. J. H. Salinas, Dong L. Wu, Nimalan Swarnalingam, Eugene V. Dao, Jorge L. Chau, Yosuke Yamazaki, Kyle E. Fitch, Victoriya V. Forsythe

Faculty Publications

While the F region is the primary focus of many ionospheric models because it contains the peak electron density, the E region is an important region for ionospheric conductivities and high-frequency radio propagation. This study analyzes modeled E regions from the newly developed PyIRI and E-PROBED models. A long-term comparison of E region predictions from E-PROBED and PyIRI with ionosonde observations is performed for three sites spanning low- (Fortaleza, Brazil), mid- (El Arenosillo, Spain), and high-latitudes (Gakona, Alaska). Modeled foE and hmE trends are compared against a combination of manually-scaled and automatically-scaled ionograms using ARTIST-5 for the period 2009–2024 for …

The Nutritional Environment And Food Access Of Female Athletes At Hbcus: A Qualitative Analysis, Nancy A. Uriegas, Zachary K. Winkelmann Ph.D., Lat, Atc, Chse, Dawn M. Emerson, Toni Torres-Mcgehee Ph.D., Lat, Atc, Facsm

Purpose:

Female student-athletes attending Historically Black Colleges and Universities (HBCUs) may encounter distinct challenges related to food access, particularly when their campuses are situated in areas with limited food availability. This study assessed food security (FS) and explored the lived experiences of HBCU female student-athletes regarding their food environments and access to nutrition.

Methods:

This qualitative study used a semi-structured interview protocol derived from quantitative data. Participants were 10 HBCU female athletes (age = 19 ± 1 years) living in on-campus dormitories; recruited after completing a quantitative study examining energy needs. The three-part semi-structured interview protocol included questions about personal …

Comparing The Cognitive And Physiological Effects Of Traditional And Virtual Reality Exercise In Overweight/Obese Adults: A Pilot Study, Emma Kelsey, Greta Ness, Grayce Bjugan, Darci Wiseman, Terence Moriarty

Faculty Publications

Research suggests that overweight/obese adults (BMI ≥ 25 kg/m²) have an elevated risk of cognitive decline. Although exercise is recommended to improve both physical and cognitive health, adherence is often low in this population. Virtual reality (VR) is an emerging strategy that may enhance exercise engagement. This pilot study compared the effects of traditional (TRAD) cycling and VR-based exercise on cognitive performance and prefrontal cortex (PFC) oxygenation (O2Hb). Eleven adults (M = 6, F = 5; BMI: 31.1 ± 2.8 kg/m²; VO2max: 30.4 ± 5.7 mL/kg/min) completed a VO2max test and two 16 min moderate-intensity cycling …

Flux Crystal Growth Of Potassium Lanthanide Double Vanadates With Lanthanide-Dependent Coordination Number Variance, Hunter B. Tisdale, Hans Conrad Zur Loye

Faculty Publications

A series of potassium rare earth double vanadates is presented. Single crystals of double vanadates with stoichiometry K₃Ln(VO₄)₂ (Ln = La, Pr, Nd, and Sm) and crystallizing in the glaserite structure type were synthesized via a molten alkali chloride/fluoride flux reaction. Different structures were observed depending on the constituent rare earth: K₃La(VO₄)₂ crystallizes in an as-of-yet unreported modification of the typical glaserite structure in the space group P2₁/c, likely due to its larger ionic size that results in an increase in the lanthanide coordination number …

Confessions Of A Beginning Dutch Learner, Kristin Lems

Faculty Publications

I have studied, taught about, and learned new languages throughout my lifespan. In fact, it has been the very core of my teaching career.  Now, I have the humbling experience of testing those truths against a new enterprise:  learning Dutch.  I spent last summer in the Netherlands, pursuing family roots and acquiring what Dutch I could.  I took no formal classes but did attend a free dropin class at the local library, where - believe me - I was the lowest learner in the lowest group! Here are some of my insights, from notes taken during that summer:

Humanizing The Base Of The Pyramid: Exploring The Influence Of Resource (Dis)Advantages On Value Creation, Ted London, Lisa Jones Christensen, Tyson Mackey, Alison Mackey, Heather Esper, Andrew Grogan-Kaylor

Faculty Publications

Base of the pyramid (BoP) scholarship emphasizes the potential for enterprises to generate profits by enhancing the wellbeing of the impoverished, often by selling socially-beneficial products (SBPs). Yet, many such BoP enterprises have experienced mixed results. We argue that this may stem from insufficient attention to how BoP consumers value SBPs and other products. We frame SBPs as a type of human capital investment and thus use human capital theory to study how the consumption of SBPs does or does not create value for consumers. Specifically, we use a novel data set from rural India to measure value creation in …

Correcting The Record: Responding To Some Legal Arguments About The 2026 Billionaire Tax Act, David Gamage, Brian D. Galle, Darien Shanske

Faculty Publications

If adopted by California voters in November of 2026, the 2026 California Billionaire Tax Act (CBTA) would impose a one-time 5% tax on the net worth of California billionaires, payable in five annual installments of 1% over 5 years (plus a small deferral charge). Critics have raised several arguments suggesting that the Act would not bring in the expected $100 billion in projected revenues because, the critics say, key parts of the Act are unconstitutional and would be subject to legal challenge. In fact, the supposed new legal challenges critics identify are mostly just very old arguments that courts have …

Gambling Away Stability: Sports Betting’S Impact On Vulnerable H, Scott R. Baker, Justin Balthrop, Mark J. Johnson, Jason Kotter, Kevin Pisciotta

Faculty Publications

We estimate the causal effect of online sports betting on households’ investment, spending, and debt management decisions using household transaction data and a staggered difference-in-differences framework. Following legalization, sports betting spreads quickly, with both the number of participants and frequency of bets increasing over time. This increase does not displace other gambling or consumption but significantly reduces savings, as risky bets crowd out positive expected value investments. These effects concentrate among frequent bettors and low-savings households. Our findings highlight the potential adverse effects of online sports betting on vulnerable households.

The Trial Of Socrates, Jonathan Van Patten

Faculty Publications

In many important ways, the trial of Socrates was not just the trial of the century, nor even the trial of the millennium. It predated the trial of Jesus, which is important for many other reasons, but Socrates’ contribution to how we think about justice and the rule of law is without equal. This Article explores the ways that this fifth-century B.C. trial, located geographically on the margin of what came to be known as the West, is at the center of what makes us a civilization. It is not simply about the drama, nor the politics of free inquiry, …

Regulatory History And Judicial Review, Todd Phillips, Anthony L. Moffa

Faculty Publications

The Administrative Procedure Act requires federal agencies to simply "incorporate in the rules adopted a concise general statement of their basis and purpose" after they receive comments from the public, and the Supreme Court ruled in Overton Park that courts are to adjudicate whether rules are arbitrary and capricious based on agencies' contemporaneous rationales. Judge-created doctrines incentivize agencies to rely on these "concise" statements to elucidate their rationales, and as a result, rulemaking preambles have ballooned in size as agencies seek to insulate themselves from critical courts.

This article contends that although the APA's statutory requirement is in tension with …

Fda After Loper Bright, Erika Lietzan

Faculty Publications

Loper Bright, which overruled the Chevron decision from 1984, tells us that a court should determine the meaning of all statutory provisions for itself, rather than deferring to the views of the federal agencies that implement those provisions. But the overruling of Chevron may have less of an impact on the U.S. Food and Drug Administration than conventional wisdom supposes. Most challenges to FDA action do not concern its statutory interpretations. And the agency prevailed in most cases involving statutory interpretation, before the Chevron doctrine took hold. After 1984, when the doctrine did apply, the agency often lost cases at …

Stoichiometry-Controlled Surface Reconstructions In Epitaxial Abo3 Perovskites For Sustainable Energy Applications, Habib Rostaghi Chalaki, Ebenezer Seesi, Gene Yang, Mohammad El Loubani, Dongkyu Lee

Faculty Publications

ABO₃ perovskite oxides are a versatile class of materials whose surfaces and interfaces play essential roles in sustainable energy technologies, including catalysis, solid oxide fuel and electrolysis cells, thermoelectrics, and energy-relevant oxide electronics. The interplay between point defects and surface reconstructions strongly affects interfacial stability, charge transport, and catalytic activity under operating conditions. This review summarizes recent progress in understanding how oxygen vacancies, cation nonstoichiometry, and electronic defects couple to atomic-scale surface rearrangements in representative perovskite systems. We first revisit Tasker’s classification of ionic surfaces and clarify how defect chemistry provides compensation mechanisms that stabilize otherwise polar or metastable …

Navigating Racist Spaces Through Radical Self-Care: A Photovoice Exploration Of The Experiences Of Black Graduate Students, Laetitia Adelson, Cherese Fine, Dion Harry, Keneisha Harrington, Rebecca Lynn Morgan Ph.D., Tomiko Smalls, Jerad Green, Courtney Allen, Anuoluwapo Bankole, Robin Phelps-Ward

Faculty Publications

This manuscript examines the impact of racist campus climates for Black graduate students at a predominantly white institution. Using a photovoice methodological design, this study illuminates students’ ability to thrive through radical self-care despite the many racist factors, incidents, and systems at the institution. The paper ends with recommendations for improving campus racial climate in graduate education.

A Comprehensive Survey On Facial Expression Generation: From Gans To Llm-Guided Multimodal Models, Murad Hasan, Rabab Abdelfattah, Kareem Abdelfatah, Mostafa Fouda, Ahmed Sherif

Faculty Publications

Facial expression generation (FEG) has emerged as a vital area in human–computer interaction, virtual avatars, and affective computing, aiming to synthesize natural and expressive facial behaviors across diverse interaction contexts. This survey presents a comprehensive analysis of recent advances in FEG, organized into six key paradigms: speech-driven expression generation, facial reaction generation, face video generation, facial animation, avatar-based generation, and text-driven expression generation. We review a wide range of model architectures, including VQ-VAEs, Generative Adversarial Networks (GANs), 3D Morphable Models (3DMMs), Transformers, and diffusion-based approaches, and compare their performance using commonly adopted evaluation metrics such as Fréchet Distance (FD), Peak …

Limits On Damages For Breach Of A Forum Selection Clause, John F. Coyle, Tanya Monestier

Faculty Publications

When a plaintiff sues in a court other than the one designated in a forum selection clause, the defendant’s remedial options are limited. It can ask the court to dismiss the case outright. Or it can ask the court to transfer the case to the designated forum. The defendant typically cannot, however, recover money damages—in the form of attorneys’ fees and related expenses—that it incurs in the course of persuading the court that transfer or dismissal is appropriate. This is because the conventional wisdom among judges has long been that damages are not available for breach of a forum selection …

The Right To Seek Joy, Tyler Rose Clemons

Faculty Publications

Within the past three years, roughly half of American states have restricted access to gender-affirming medical treatment for children. In this article, I argue that these bans violate transgender children’s right to liberty guaranteed by the Fourteenth Amendment’s Due Process Clause. I do so by excavating the Framers’ understanding of liberty as the right to seek joy. Rooted in the philosophies of John Locke and Epicurus, the Framers understood liberty as the right to make important life decisions according to one’s subjective preferences without undue interference from the government. Based on this understanding, I develop a new framework for substantive …

Treatment Sentences, Evelyn Malavé

Faculty Publications

One of the most common mandates of a non-incarceratory sentence is to submit to treatment. Across the criminal legal system, from problem-solving courts to probation, millions of defendants sentenced to non-incarceratory sentences—including people not diagnosed with a substance abuse disorder—are required to attend drug treatment programs. After decades of policies that criminalized drug use, non-incarceratory sentences that match people with treatment may appear to be a step forward—or at least not the most pressing problem.

But criminal law scholarship has not fully reckoned with the harms of treatment sentences, including the harms of mandated treatment itself. Analysis of treatment sentences …

Using Network Models To Understand Biological Signaling Architecture, Russ White, Emily Brown Reeves, Gerald L. Fudge

Faculty Publications

Engineers have developed abstract network models to better understand the recurring problems faced by communication systems. This paper argues that these models can be generalized to describe biological communications systems given that they share many requirements with human-designed systems, including functional requirements and physical constraints. Leveraging collaboration, biologists and engineers can work together to use well-understood communication systems, designed to carry data across a computer network, as a model for analyzing less well-understood biological communication systems in order to make predictions and uncover previously unknown functionalities. To illustrate this approach, we apply the Recursive Internet Network Architecture model (RINA) to …

Pullulan Production From Lignocellulosic Plant Biomass Or Starch-Containing Processing Coproduct Hydrolysates, Thomas P. West

Faculty Publications

The complex polysaccharide pullulan is characterized as a glucose-containing biopolymer that is both water-soluble and neutral in polarity. A variety of commercial applications exist for pullulan, including its utilization as a flocculant, a blood plasma substitute, a food additive, a dielectric material, an adhesive, or a packaging film. The fungus Aureobasidium pullulans has used several hydrolysates derived from plant biomass or starch-containing processing coproducts to support polysaccharide production. These include various plant biomass or processing coproduct streams such as lignocellulosic-containing peat, prairie grass, stalks, hulls, straw, shells, and pods or starch-containing coproducts from the processing of corn, rice, jackfruit seeds, …

Against Doctrinal Siloing: Harmonizing Fiscal Federalism And The U.S. Constitution, David Gamage, Darien Shanske

Faculty Publications

This Essay argues that constitutional law’s treatment of fiscal federalism has fractured into a bewildering collection of doctrinal silos. Federal spending that pressures states, federal preemption of state taxes, the Dormant Commerce Clause, sovereign immunity, Section 5 of the Fourteenth Amendment, and the federal taxing power are all analyzed through distinct tests, even when they implicate the same basic conflict between federal authority and state fiscal autonomy. The result is not just theoretical confusion but inconsistent constitutional answers. Current doctrine can protect states from comparatively modest liabilities while leaving uncertain whether Congress may displace large swaths of state revenue authority. …

My Negotiation Chatbot Toby And Pedagogical Governance, Renee Henson

Faculty Publications

The use of artificial intelligence (AI) chatbots is exploding. Adolescents increasingly prefer interactions with AI companions over peers. Adults rely on these systems for health planning, therapy, administrative assistance, nutrition guidance, and even simulated “romantic relationships.” Individuals and institutions are adopting AI tools at a pace that far exceeds the development of governance frameworks.

I developed Toby for use in my first-year Lawyering: Problem-Solving and Dispute Resolution (“Lawyering”) course to expose students to the dynamics of negotiating against an opposing counsel with a difficult personality—a type of adversary all too common in legal practice, yet difficult to prepare for. Toby …

Mental And Physical Humanlikeness In Artificial Intelligence Influencers: Effects On Humanness, Eeriness, And Consumer Responses, Terry Kim Ph.D., Hyunjoo Im

Faculty Publications

Artificial intelligence (AI) influencers, nonhuman characters powered by AI, have garnered a significant following on social media in recent years. Through two between-subjects online experiments (n = 957), this study investigates the impact of AI influencers' appearance realism and self-disclosure on consumer perceptions (humanness and eeriness) and their downstream responses (intention to self-disclose, intention to follow the advice, and brand attitude). Drawing from anthropomorphism and theory of mind, this study emphasizes the distinction of two dimensions of AI influencers' humanlikeness (physical and mental) which differently affect the humanness and eeriness of the AI influencer. Results indicate that the AI …

De-Skilling Or Re-Skilling? The Case For Smarter Writing Assignments, John Lande

Faculty Publications

This article challenges the assumption that AI inevitably leads to the de-skilling of law students.  Some faculty understandably fear that students will use AI to bypass critical thinking and avoid meaningful effort.  This article reframes AI as a potential catalyst for improving legal education rather than inherently a threat.

Concerns about de-skilling generally are based on the assumption that faculty will not change traditional writing assignments.  This article analyzes why these assignments often fail to help students develop strong analytical and writing skills. These include limited instruction in basic writing skills, poor design, lack of feedback, and faculty inertia in …

Serum Protein Signatures For Breast Cancer Detection In Treatment-Naïve African American Women Using Integrated Proteomics And Pattern Analysis, Padma Tadi Uppala, Elmer Rivera, Hyun J. Kwon, Sharon S. Lum

Faculty Publications

Breast cancer is the leading cause of cancer-related mortality in African American (AA) women. In this study we evaluated the serum proteomic profile of AA women with breast cancer using an integrated proteomic framework with multivariate pattern analysis. Using 2D-DIGE, thousands of serum protein spots were detected across 33 gels; 46 spots met criteria for presence, statistical significance, and differential expression. Proteins from the spots were identified by MALDI-TOF/TOF and matched in curated databases, highlighting serum biomarkers including ceruloplasmin, alpha-2-macroglobulin, complement component C3 and C6, alpha-1-antitrypsin, alpha-1B-glycoprotein, alpha-2-HS-glycoprotein and haptoglobin-related protein. LC-MS/MS analysis revealed 163 differentiating peptides after imputing and …

When Money Moves In: The Consequences Of Housing Wealth, Darren Aiello, Jason Kotter, Gregor Schubert

Faculty Publications

We construct a novel dataset of millions of household moves over 25 years to examine how housing wealth affects purchase decisions. We find that a $1 exogenous increase in housing equity leads movers to pay a $0.06 premium on their next home, controlling for property characteristics and time-varying local prices. This behavior is driven by search frictions— wealthier households pay a premium rather than incur additional search costs. In aggregate, these decisions spill over to the broader housing market and cause upward regional price pressure. A 10% increase in equity gain among incoming movers increases local house price growth by …

Mandatory Cooperation Under International Law, Evan J. Criddle, Evan Fox-Decent

Faculty Publications

Humanity in the twenty-first century faces serious global challenges and crises, including pandemics, nuclear proliferation, violent extremism, refugee migration, and climate change. None of these calamities can be averted without robust international cooperation. Yet, national leaders often assume that because their states are sovereign under international law, they are free to opt in or out of international cooperation as they see fit. This book challenges conventional wisdom by showing that international law requires states to cooperate with one another to address matters of international concern – even in the absence of treaty-based obligations. Within the past several decades, requirements to …

Developer Perspectives On Licensing And Copyright Issues Arising From Generative Ai For Software Development, Trevor Stalnaker, Nathan Wintersgill, Oscar Chaparro, Laura A. Heymann, Massimiliano Di Penta, Daniel M. German, Denys Poshyvanyk

Faculty Publications

Despite the utility that Generative AI (GenAI) tools provide for tasks such as writing code, the use of these tools raises important legal questions and potential risks, particularly those associated with copyright law. As lawmakers and regulators respond to these questions, the views of users can offer relevant perspectives. In this article, we provide: (1) a survey of 574 developers on the licensing and copyright aspects of GenAI for coding, as well as follow-up interviews; (2) a snapshot of developers’ views at a time when GenAI and perceptions of it were rapidly evolving; and (3) an analysis of developers’ perspectives, …

The Specter Of Jury Nullification, Anna Offit

Faculty Publications

Attention to the trial of Luigi Mangione has renewed debate about nullification—the jury’s inviolate power to acquit a defendant contrary to the evidence presented. Jury nullification proponents hold that it is a mechanism of last resort for refusing to apply laws that conflict with the public conscience. Opponents, by contrast, argue that nullification undermines the law by diminishing its legitimacy. To prosecutors and defense attorneys, however, these arguments are immaterial: Jury nullification is part of the institutional landscape of the contemporary jury trial and thus must be treated as a potentiality—a feature of the agnostic, strategic, and ethical terrain of …
