Million-Dollar Mysteries: Recent Complex Patent Cases Lost To Rule 36, Dennis D. Crouch

Faculty Publications

This article examines the Federal Circuit's continued use of Rule 36 summary affirmances to dispose of complex patent cases without written opinions. Through analysis of eight recent Rule 36 cases decided in early 2025, the author demonstrates that sophisticated legal issues involving millions of dollars are being summarily affirmed despite presenting novel and important questions of patent law. The cases discussed involve design patent evidentiary standards, jury trial rights for hybrid legal-equitable claims, analogous art determinations, claim construction, written description requirements, and PTAB procedural issues. The author argues that while the court may be avoiding difficult cases with complex factual …

Joyful Justice, Alexandra Kogl

Faculty Publications

Political Science is not an obviously joyful discipline, and wrestling with injustice in the classroom is not an intuitive way to open the door to joy. But when students and professor alike practice compassion for victims of injustices (such as sexual violence and white supremacy) and for each other, they sometimes find the kind of common ground that allows joy into the room. Treating one another as peers in a community aimed at seeking to understand what justice is and what it feels like, we experience justice as beautiful, shared work that we can practice at a small scale, setting …

Good agreement with available experiments has been demonstrated.

Accelerated Multiobjective Calibration Of Fused Deposition Modeling 3d Printers Using Multitask Bayesian Optimization And Computer Vision, Craig S. Ganitano, Benji Maruyama, Gilbert L. Peterson

Faculty Publications

Proper process parameter calibration is critical to the success of fused deposition modeling (FDM) three-dimensional (3D) printing, but is time-consuming and requires expertise. While existing systems for autonomous calibration have demonstrated success in calibrating for a single objective, users may need to balance multiple conflicting objectives. Herein, an easily deployable, camera-based system for autonomous calibration of FDM printers that optimizes for both part quality and completion time is presented. Autonomous calibration is achieved through a novel, multifaceted computer vision characterization and a multitask learning extension to Bayesian optimization. The system is demonstrated on four popular filament types using two distinct …

Variations In Hawaiian Plume Flux Controlled By Ancientmantle Depletion, Paul Béguelin, Andreas Stracke, Maxim D. Ballmer, Shichen Huang, Michael Wilig, Michael Bizimis

Faculty Publications

Mantle plumes—upwellings of buoyant rock in Earth's mantle—feed hotspot volcanoes such as Hawai‘i. The size of volcanoes along the Hawai‘i–Emperor chain, and thus the magma flux of the Hawaiian plume, has varied over the past 85 million years. Fifteen and two million years ago, rapid bursts in magmatic production led to the emergence of large islands such as Pūhāhonu, Maui Nui and Hawai‘i, but the underlying mechanisms remain enigmatic. Here, we use new radiogenic Ce–Sr–Nd–Hf isotope data of Hawaiian shield lavas to quantify the composition and proportion of the different constituents of the Hawaiian plume over time. We find that …

A Numerical Assessment Of Ocean Alkalinity Enhancement Efficiency On A River-Dominated Continental Shelf—A Case Study In The Northern Gulf Of Mexico, Yanda Ou, Z. George Xue, Xinping Hu

Faculty Publications

A robust high-resolution coupled hydrodynamic-biogeochemical model was applied to the northern Gulf of Mexico to assess the efficiency of river- and ocean-sourced ocean alkalinity enhancement (OAE). Sensitivity tests indicate that the effectiveness of OAE-induced CO2 uptake is primarily influenced by the amount of alkalinity introduced and local wind-driven mixing, with the former determining the overall uptake and the latter affecting short-term variability. Compared to ocean-sourced OAE (direct ocean release), river-sourced OAE (elevated river alkalinity) is more effective and sustainable. River-sourced OAE has higher CO2 uptake efficiency with reduced spatial and temporal uncertainty and greater overall CO2 uptake. For river-sourced OAE, …

Subramaniam, Vivitskaia Tulloch, Andrea Bryndum-Buchholz

Faculty Publications

As the urgency to evaluate the impacts of climate change on marine ecosystems increases, there is a need to develop robust projections and improve the uptake of ecosystem model outputs in policy and planning. Standardizing input and output data is a crucial step in evaluating and communicating results, but can be challenging when using models with diverse structures, assumptions, and outputs that address region-specific issues. We developed an implementation framework and workflow to standardize the climate and fishing forcings used by regional models contributing to the Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) and to facilitate comparative analyses across …

Our study presents a data-driven analysis across 312 bacterial species and 154 unique metabolites to enhance the understanding of underlying metabolic processes in gut bacteria. The focus of the study was to create a strategy to generate a theoretical (negative) set for binary classification models to predict the consumption and production of metabolites in the human gut microbiome. Results: Our models achieved median balanced accuracies of 0.74 for consumption predictions and 0.95 for production predictions, highlighting the effectiveness of this approach in generating reliable negative …

Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Strain Ccmp 1334 Of The Marine Cyanobacterium Synechococcus (Cyanophyceae), Alyssa K. Sharbaugh, Edward A. Laws

Faculty Publications

The marine cyanobacterium Synecococcus sp. (CCMP 1334) was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nutrient availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21, 24, 28, 32, and 35°C. The maximum nutrient-replete growth rate was ~1.15 day⁻¹ at 32–35°C. Median nutrient-replete growth rates were higher at 1000 ppmv than at 400 ppmv pCO2 at all temperatures. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate (i.e., growth rate ÷ nutrient-replete growth rate) but decreased with increasing temperature. …

Frederiks, Daniela Huppenkothen, Brendan O-Connor, Oliver J. Roberts, Zorawar Wadiasingh, George Younes, Narayana Bhat, Michael S. Briggs, Malte Busmann, Adam Goldstein, Daniel Gruen, Lei Hu, Chryssa Kouveliotou, Michela Negro, Antonella Palmese, Arno Riffeser, Lorenzo Scotton, Dmitry S. Svinkin, Peter Veres, Raphael Zöller

Faculty Publications

Magnetar giant flares (MGFs) are the extremely short, energetic transients originating from highly magnetized neutron stars. When observed in nearby galaxies, these rare events are nearly indistinguishable from cosmological short gamma-ray bursts. We present the analysis of GRB 231115A, a candidate extragalactic MGF observed by Fermi/GBM and localized by INTEGRAL to the starburst galaxy M82. This burst exhibits distinctive temporal and spectral characteristics, including a short duration and a high peak energy, consistent with known MGFs. Time-resolved analysis reveals rapid spectral evolution and a clear correlation between luminosity and spectral hardness, providing robust evidence of relativistic outflows. Archival Chandra data …

Beyond Water Surface Profiles: A New Iterative Methodology For 2d Model Calibration In Rivers Using Velocity Data From Multiple Cross-Sections, Fabian Rivera-Trejo, Gabriel Soto-Cortes, Kory M. Konsoer, Eddy J. Langendoen, Gaston Priego-Hernandez

Faculty Publications

Observed longitudinal water-surface profiles are commonly used to calibrate river hydrodynamic models, relying on assumptions of lateral uniformity in water surface elevation and velocity distribution. While suitable for 1D models, this approach has limitations in regard to 2D model calibration. When 2D flow measurements are available, a more robust quantitative evaluation is necessary to assess model accuracy. This study introduces a novel methodology to improve 2D model calibration and evaluate performance. High-resolution bathymetric and hydrodynamic data collected with a multibeam echosounder (MBES) and acoustic Doppler current profiler (ADCP) were aligned to compare observed and simulated flow velocities at matching spatial …

Ceres: Organic-Rich Sites Of Exogenic Origin?, R. Sarkar, A. Nathues, M. Hoffmann, E. Cloutis, K. Mengel, P. Singh, G. Thangjam, J. Hernandez, S. Karunatillake, M. Coutelier

Faculty Publications

Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari and Urvara craters. The origin of organics, either endogenic or exogenic, in these fresh exposures is still under debate. This study addresses the origin of the organics by analyzing their global distribution and geologic context. Our first step involved a global search for organic-rich sites that might have escaped previous detections. We achieved this by using a deep neural network, utilizing spectral …

Predicting Individual Long-Term Prognosis Of Spatial Neglect Based On Acute Stroke Patient Data, Lisa Röhrig, Daniel Wiesen, Dongyun Li, Chris Rorden, Hans-Otto Karnath

Faculty Publications

One of the most pressing questions after a stroke is whether an individual patient will recover in the long term. Previous studies demonstrated that spatial neglect—a common cognitive deficit after right hemispheric stroke—is a strong predictor for poor performance on a wide range of everyday tasks and for resistance to rehabilitation. The possibility of predicting long-term prognosis of spatial neglect is therefore of great relevance. The aim of the present study was to test the prognostic value of different imaging and non-imaging features from right hemispheric stroke patients: individual demographics (age, sex), initial neglect severity and acute lesion information (size, …

Simulations Of Attosecond Metallization In Quartz And Diamond Probed With Inner-Shell Transient Absorption Spectroscopy, Lucas Kurkowski, Adonay Sissay, Mengqi Yang, Alexander Meyer, Kenneth Lopata

Faculty Publications

When dielectrics are hit with intense infrared (IR) laser pulses, transient metalization can occur. The initial attosecond dynamics behind this metallization are not entirely understood. Therefore, simulations are needed to understand this process and to help interpret experimental observations of it, such as with attosecond transient absorption (ATA). In this paper, we present first-principles simulations of ATA based on bulk-mimicking clusters and real-time time-dependent density functional theory (RT-TDDFT), with Koopmans-tuned range-separated hybrid functionals and Gaussian basis sets. Our method gives good agreement with the experiment for the breakdown threshold in silica and diamond. This breakdown voltage corresponds to a Keldysh …

Faculty Publications

Background/Objectives: Cancer is a leading cause of death. However, recently developed immunotherapies have shown significant promise to improve cancer treatment outcomes and survival rates. Pembrolizumab, a cancer immunotherapy drug, enables a strong T-cell response specifically targeting cancer cells to improve patient outcomes in more than 16 types of cancer. The increasing demand for pembrolizumab, the highest selling drug in 2023, increases global dependence on drug production, which can be vulnerable to supply chain disruptions. Methods: Cell-free protein synthesis (CFPS) is a rapid in vitro protein production method that could provide the production of an immunotherapy drug in an emergency and …

Federal Circuit’S Filing Requirements: A Trap For Even The Experts, Dennis D. Crouch

Faculty Publications

The Federal Circuit Court of Appeals has established itself as the most procedurally demanding appellate court in the federal system, routinely issuing notices of non-compliance even to the nation's most experienced practitioners. This essay examines the pervasive nature of filing errors in Federal Circuit appeals, analyzing examples from recent cases involving prestigious law firms and institutions. Despite the court's 2023 memo detailing "Common Filing Errors," practitioners continue to struggle with requirements ranging from form completion and addenda formatting to confidentiality designations and caption compliance. The article argues that the prevalence of these issues among highly qualified counsel suggests a systemic …

Gotta Take My Avatar Shopping: Impacts Of Interactive Virtual Shopping In Esport, Yongjin Hwang, Keshav Gupta

Faculty Publications

Purpose

Esports game developers are incorporating interactive virtual shopping (IVS) experiences into their products to facilitate consumer–brand interactions. Despite the potential influence of IVS, existing research lacks an understanding of its impact on consumers’ overall affect– particularly game enjoyment, a critical factor in sustaining engagement with esports products – and on attitudinal change toward brands in the real world.

Design/methodology/approach

An experiment was designed to examine the impact of shopping in the virtually interactive esports marketplace on game enjoyment. Mediating effects of positive change in brand attitude, perceived realism and character attachment and the moderating effect of self-avatar gender congruity …

Faculty Publications

The conversation about translanguaging is creating waves around the world, and Illinois is no exception. This column serves to remind the reader of some of the antecedents to this influential concept (“old wine”), predicts how this movement may affect your education setting (“new bottle”), and lays out a few of the aspects of translanguaging that may indeed be “new wine.”

Spin Caloritronics As A Probe Of Nonunitary Superconductors, Taiki Matsushita, Takeshi Mizushima, Yusuke Masaki, Satoshi Fujimoto, Ilya Vekhter

Faculty Publications

Superconducting spintronics explores the interplay between superconductivity and magnetism, sparking substantial interest in nonunitary superconductors as a platform for magneto-superconducting phenomena. However, identifying nonunitary superconductors remains challenging. We demonstrate that spin current driven by thermal gradients sensitively probes the nature of the condensate in nonunitary superconductors. Spin polarization of the condensate in momentum space induces the superconducting spin Seebeck effect, where a spin current is generated along thermal gradients without a thermoelectric charge current. Notably, the nonvanishing superconducting spin Seebeck effect provides a smoking gun evidence of nonunitary superconductivity because it reflects the spin polarization of the condensate in momentum …

Public Trials And Plain Error, Stephen Smith

Faculty Publications

Courts are divided on the question of how Sixth Amendment public trial violations should be evaluated on appeal when a criminal defendant fails to object at trial to a courtroom closure. Typically, failing to object triggers plain error review on appeal, which demands a higher threshold of harm to obtain reversal compared to when an objection has been made at trial. Should this type of review also apply in its usual form to public trial errors? The article concludes that it should, despite the fact that public trial violations are considered “structural,” and, when properly preserved, do not require a …

Between Pedagogical Content Knowledge And Confidence: A Case Study Of Pronunciation Training And Teacher Preparation, Lena Barrantes-Elizondo, Joshua Gordon

Faculty Publications

While many teachers do not feel confident teaching pronunciation because of limited preparation in different areas, research has demonstrated positive effects of training in pronunciation pedagogy, as teachers who receive such training develop cognitions (i.e., knowledge, beliefs, thoughts, actions) that align with current tenets of pronunciation pedagogy. Drawing on this assertion, this paper reports the results of a qualitative case study with five pre-service teaching-English-to-speakers-of-other-languages (TESOL) teachers enrolled in a pedagogical pronunciation course as part of their teacher training program. The study’s main purpose was to understand the role of training in developing content knowledge (CK) and pedagogical content knowledge …

“The Centrality Of ‘Life’ For Johannine Ethics”, Craig R. Koester

Faculty Publications

Jan van der Watt has described ethics as rational and systematic reflection on actions that are deemed positive or negative. Basic questions involve the point of departure and the aim of ethical action. He rightly identifies God as the authoritative center for Johannine ethics and makes two observations that warrant further development. First, as the point of departure, “God is the living God (6:57), the God who is life and gives life,” and Jesus too “is and brings life.” Second, in “line with the task of Jesus, the aim of believers is to give, sustain, and promote life.” “Promoting life …

Injunctive Restraint, Cassandra Burke Robertson

Faculty Publications

Preliminary injunctions against government action have evolved from extraordinary remedies into routine instruments of political contestation, with both Republican and Democratic administrations finding their initiatives halted by nationwide judicial orders. These injunctions serve vital functions in our constitutional system—preventing irreparable harm to fundamental rights and providing necessary checks on executive power in an era of congressional gridlock. Yet their increasing use has generated legitimate institutional concerns, particularly when a single district judge, often selected through strategic forum shopping, can unilaterally suspend national policies of significant importance. This Article examines this tension between the necessary role of nationwide injunctions in protecting …

Causation’S Due Process Dimensions, Cassandra Burke Robertson, Charles W. "Rocky" Rhodes

Faculty Publications

For decades, courts have grappled with the tension between compensating victims of mass harms and maintaining fairness to defendants when causation is difficult to prove. This Article argues that the Supreme Court’s due process jurisprudence provides a relevant framework for navigating this tension. We contend that the Court over the last three decades has established a consistent due process approach in punitive damages and personal jurisdiction cases, which is rooted in antecedents tracing to the nineteenth century and relies on a nexus of interests that balances individual rights, state interests, and federalism concerns. This framework, we argue, has significant implications …

Patient Autonomy, Public Safety, And Drivers With Cognitive Decline, Sharona Hoffman, Cassandra Burke Robertson

Faculty Publications

With a growing elderly population, cognitive decline in drivers has become a significant public safety concern. Currently, over thirty-two million individuals who are seventy or older have driver’s licenses, and that number is growing quickly. In addition, almost ten percent of U.S. seniors (those sixty-five and older) have dementia, and an additional twenty-two percent have mild cognitive impairment. Between a quarter and a half of individuals with mild to moderate dementia still drive. As cognitive abilities such as memory, attention, and decision-making skills deteriorate, a driver's ability to operate a vehicle safely can be compromised. This not only puts the …

Reimagining Compliance: Explainable Ai Models For Financial Regulatory Audits, Hrishikesh Desai

Faculty Publications

This chapter develops an analytical model for Explainable AI (XAI) designed to support major types of banking regulatory compliance audits. Financial institutions increasingly rely on AI for efficiency in compliance tasks, but the opacity of complex models creates challenges in meeting regulatory transparency requirements. The proposed mathematical framework incorporates explainability as a quantifiable constraint in the optimization of AI models across five critical audit categories: CAMELS examinations, BSA/AML compliance, Consumer Compliance, IT Audits, and Internal Audits. By quantifying explainability through information- theoretic measures and Shapley values, the model balances predictive performance with regulatory requirements. The methodology is validated through a …

The Importance Of Fauna-Mediated Sediment O2 Consumption In The Ngom Hypoxic Zone, Hannah Beck, Kanchan Maiti

Faculty Publications

The northern Gulf of Mexico (NGOM) coastal shelf adjacent to the Mississippi and Atchafalaya rivers system experiences strong seasonal hypoxia in the late summer and coupled physical-biological models suggest that hypoxia formation in the NGOM is sensitive to benthic biogeochemical processes. However, the processes driving sediment oxygen consumption and their relationship to bottom oxygen concentration remain enigmatic. This study for the first time concurrently measured in situ total oxygen uptake (TOU) and diffusive oxygen uptake (DOU) during two different hypoxia seasons. The relatively large DOU: TOU ratio of 0.33 ± 0.07 observed during this study suggests more significant benthic infauna …

The Impact Of Seasonal Hydrological Disturbances On The Presence And Formation Of Toxic Cyanobacteria Blooms In Coastal Louisiana, Courtney Nicole Hammond, Sibel Bargu, Caitlin R.R. Turner, Matthew Hiatt, John R. White

Faculty Publications

Estuaries in the Gulf, especially Lake Pontchartrain Estuary in southeastern Louisiana, USA, are experiencing significant changes due to climate change and coastal restoration efforts. Lake Pontchartrain Estuary receives nutrient-rich Mississippi River water through a controlled diversion called Bonnet Carré Spillway (BCS), which has been associated with toxic cyanobacterial blooms (cyanoHABs). This study examines the seasonal factors influencing cyanoHABs in the Lake Pontchartrain Estuary when the BCS is closed, addressing gaps in the understanding of HABs related to other physical drivers. Field samples collected in 2021, during the closure of the spillway, revealed significant evidence of seasonal variations in cyanoHAB formation. …
