Background

Globally, alarmingly high rates of maternal and infant mortality and morbidity persist. A constellation of health system and social factors contribute to this, including poor quality and barriers to accessing health care, including preventive services. As such, there have been calls for a redesign of maternal and child health (MCH) services. Although group care has primarily been tested in antenatal settings, it offers a promising redesign that optimizes maternal and child health care, survival, and well-being. The purpose of this study was to produce a blueprint of an adapted group care model that integrates postnatal maternal care, well-child care, …

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 …

Polymer Dynamics At Low Molecular Weight Of Poly(Butylene Oxide) Star Polymers, Karin J. Bichler, Bruno Jakobi, Gerald J. Schneider

Faculty Publications

Star polymers are an interesting class of polymers to study based on their shape and dynamics. We use complementary techniques to study the polymer dynamics of star polymers with shorter side chains and compare them with linear counterparts. Using dielectric spectroscopy and rheology allows the extraction of the critical molecular weight using two different approaches. Furthermore, the reduction of the dielectric normal mode relaxation time shows a temperature as well as molecular weight dependent factor. Based on our dielectric spectroscopy results and taking as the limiting case based on theory, a temperature of T = 201.5 K is required which …

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 …

Si-Doped Ain Using Pulsed Metalorganic Chemical Vapor Deposition And Doping, Tariq Jamil, Abdullah Al Mamun Mazumder, Mohammod Ali, Jingyu Lin, Hongxing Jiang, Grigory Simin, M. Asif Khan

Faculty Publications

In this paper we describe a pulsed metalorganic chemical vapor deposition (MOCVD) Si-doping approach for AlN epilayers over bulk AlN. The Al-rich growth/doping conditions in the pulsed MOCVD process resulted in n-AlN layers with transmission line model currents that were an order higher than for structures on layers that were grown/doped at identical temperatures using the conventional MOCVD process. Our work demonstrated that like the other reported approaches such as UV exposure during growth, the pulsed MOCVD process is also very effective in reducing point defects by the defect quasi-Fermi level-chemical potential control.

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 …

Streamlined Production, Protection, And Purification Of Enzyme Biocatalysts Using Virus-Like Particles And A Cell-Free Protein Synthesis System, Seung O. Yang, Joseph P. Talley, Gregory H. Nielsen, Kristen M. Wilding, Bradley Charles Bundy

Faculty Publications

Enzymes play an essential role in many different industries; however, their operating conditions are limited due to the loss of enzyme activity in the presence of proteases and at temperatures significantly above physiological conditions. One way to improve the stability of these enzymes against high temperatures and proteases is to encapsulate them in protective shells or virus-like particles. This work presents a streamlined, three-step, cell-free protein synthesis (CFPS) procedure that enables rapid in vitro enzyme production, targeted encapsulation in protective virus-like particles (VLPs), and facile purification using a 6× His-tag fused to the VLP coat protein. This process is performed …

Empowering Sustainable Development: Solar Energy For Enhanced Weather Resilience, Aly Mousaad Aly

Faculty Publications

This paper examines the impact of photovoltaic (PV) panels on wind loads in low-rise buildings with gable roofs, emphasizing their potential to promote sustainable energy solutions while improving structural integrity. We hypothesize that PV panels can effectively reduce wind-induced forces on roofing components. Experiments using a 1:7.5 scale model in an open-jet wind facility compared bare roofs to those equipped with PV panels across three configurations. Results show that PV panels can decrease total wind forces on the roof by 45% to 63%, depending on configuration and wind direction. These findings suggest that additional structural reinforcement may not be necessary …

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, …

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 …

What's The Matter With Batna? It's Misleading And Doesn't Help Advance Parties' Important Interests, John Lande

Faculty Publications

Many dispute resolution experts misunderstand the concept of BATNA (the best alternative to a negotiated agreement), believing that it is the most favorable possible outcome if the parties don’t settle. In fact, BATNA isn’t an expected result. It’s a course of action, not the value resulting from the course of action.

Attorneys often make unrealistic predictions of court outcomes because of inherent uncertainty and cognitive biases. Moreover, parties have many intangible interests that aren’t included in estimates of BATNA values.

This article offers suggestions for attorneys and mediators to advance clients’ interests by better understanding and valuing non-settlement outcomes.

Threat Perceptions, Defensive Behaviors, And The Perceived Suicide Prevention Value Of Specific Firearm Storage Practices, Michael D. Anestis, Craig J. Bryan, Anna Belle O. Bryan, Daniel W. Capron

Faculty Publications

Introduction: Secure firearm storage has been proposed as a suicide prevention method within the military; however, secure storage practices are uncommon. Service members may perceive limited value in secure storage as a suicide prevention tool and threat-related factors may influence such perceptions. Method: A nationally representative sample of firearm-owning military service members (n = 719) was recruited between December 3, 2021 and January 4, 2022 to complete a self-report survey by Ipsos using their KnowledgePanel calibration approach to optimize representativeness. Results: Threat sensitivity was associated with less perceived suicide prevention value across all within-home storage practices as well as out-of-home …

Cultural Consensus Modeling To Identify Culturally Relevant Reasons For And Against Suicide Among Black Adolescents, Ryan M. Hill, Danielle Busby, Jennifer L. Brown, Eric Sumlin, Estefania Fernandez, Carla Sharp

Faculty Publications

Introduction: The development of evidence-based treatments relies on accurate theoretical frameworks sensitive to the lived realities of the populations from which they are derived. Yet, the perspectives of Black youth are vastly underrepresented in extant theories of suicidal behavior. Cultural Consensus Modeling provides an evidence-based approach for developing a culturally informed understanding of suicide risk among Black youth. Method: Participants were 50 Black adolescents (Mage = 16.20 years; 76.0% male) who completed Phase 1 of a Cultural Consensus Modeling study. Participants freely listed reasons for suicide and reasons for living among similar peer Black youth. Responses were synthesized and coded …

Deceptive Illusory Cues Can Influence Orthogonally Directed Manual Length Estimations, Shijun Yan, Jan M. Hondzinski

Faculty Publications

We examined participants’ abilities to manually estimate one of two perpendicular line segment lengths using curved point-to-point movements. Configurations involved symmetrical, unsymmetrical, and no bisection in upright and rotated orientation alterations to vertical-horizontal (V-H) illusions, where people often perceive longer vertical than horizontal segments for equal segment lengths. Participants used two orthogonally directed movements for length estimations: positively proportional (POS) – where greater fingertip displacement involved longer length estimation between configuration intersection start position and fingertip end, and negatively proportional (NEG) – where greater fingertip displacement from the screen edge start position toward configuration intersection involved a shorter length estimation …

A Data-Driven Approach To Enhance The Prediction Of Bacteria–Metabolite Interactions In The Human Gut Microbiome Using Enzyme Encodings And Metabolite Structural Embeddings, Gopal Srivastava, Michal Brylinski

Background: The human gut microbiome is critical for host health by facilitating essential metabolic processes. 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 …

Faculty Publications

We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) onboard JWST in June 2023 at an MIR luminosity LMIR ≈ 10³⁶ erg s⁻¹ exceeding past infrared levels by about a factor of 10. In contrast, the X-ray flux is much fainter than the historical average, in the source’s now-persistent ‘obscured’ state. The MIRI low-resolution spectrum shows a plethora of emission lines, the strongest of which are consistent with recombination in the hydrogen Pfund (Pf) series and higher. Low-amplitude (∼1 per cent) but highly significant peak-to-peak …

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. …

Nodal Finite Element Approximation Of Peridynamics, Prashant K. Jha, Patrick Diehl, Robert Lipton

Faculty Publications

This work considers the nodal finite element approximation of peridynamics, in which the nodal displacements satisfy the peridynamics equation at each mesh node. For the nonlinear bond-based peridynamics model, it is shown that, under the suitable assumptions on an exact solution, the discretized solution associated with the central-in-time and nodal finite element discretization converges to a solution in the L² norm at the rate C1Δt+C2h²/ϵ². Here, Δt, h, and ϵ are time step size, mesh size, and the size of the horizon or nonlocal length scale, respectively. Constants C1 and C2 are independent of h …

Defect Bound States In The Continuum Of Bilayer Electronic Materials Without Symmetry Protection, Daniel Massatt, Stephen P. Shipman, Ilya Vekhter, Justin H. Wilson

Faculty Publications

We analyze a class of bound defect states in the continuum electronic spectrum of bilayer materials, which emerge independent of symmetry protection or additional degrees of freedom. Taking graphene as a prototypical example, our comparative analysis of AA- and AB-stacked bilayer graphene demonstrates that these states originate from the intrinsic algebraic structure of the tight-binding Hamiltonian when trigonal warping is neglected rather than any underlying symmetry. The inclusion of trigonal warping and higher-order hoppings broadens the bound states into long-lived resonances. This discovery provides a distinct pathway to defect and band-structure engineering. We conclude with a proposed protocol for observing …

Orbifolds And Minimal Modular Extensions, Chongying Dong, Siu Hung Ng, Li Ren

Faculty Publications

Let V be a simple vertex operator algebra and G a finite automorphism group of V such that V^G is regular, and the conformal weight of any irreducible g-twisted V-module N for g∈G is nonnegative and is zero if and only if N=V. It is established that if V is holomorphic, then the V^G-module category CV^G is a minimal modular extension of E=Rep(G), and is equivalent to the Drinfeld center Z(VecG^α) as modular tensor categories for some α∈H³(G,S¹) with a canonical embedding of E. Moreover, the collection Mv(E) of equivalence …

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 …

Refining A Chain Theorem From Matroids To Internally 4-Connected Graphs, Chanun Lewchalermvongs, Guoli Ding

Faculty Publications

Graph theory and matroid theory are interconnected with matroids providing a way to generalize and analyze the structural and independence properties within graphs. Chain theorems, vital tools in both matroid and graph theory, enable the analysis of matroid structures associated with graphs. In a significant contribution, Chun, Mayhew, and Oxley [2] established a chain theorem for internally 4-connected binary matroids, clarifying the operations involved. Our research builds upon this by specifying the matroid result to internally 4-connected graphs. The primary goal of our research is to refine this chain theorem for matroids into a chain theorem for internally 4-connected graphs, …

Butterfly Species Vary In Sex-Specific Sodium Accumulation From Larval Diets, Luis Y. Santiago-Rosario, Alexander M. Shephard, Emilie Snell-Rood, Achim D. Herrmann, Kyle E. Harms

Faculty Publications

Sodium is essential for animals, and its heterogeneous distribution can cause a range of phenomena, from sodium-seeking behaviours to impacting their performance. Although sodium content in soils and plants is relatively well documented, data for higher trophic levels are limited. Knowledge of the variation in sodium in lower trophic levels could have implications for understanding the behaviour and physiology of species at higher levels. We investigated the variation in tissue sodium concentration between males and females of four butterfly species. Puddling behaviour of Lepidoptera suggests sodium needs of males are generally greater than females, thus, we predicted males would accumulate …

Increased Expression Of The Small Lysosomal Gene Svip In The Drosophila Gut Suppresses Pathophysiological Features Associated With A High-Fat Diet, Brennan M. Mercola, Tatiana V. Villalobos, Jocelyn E. Wood, Ankita Basu, Alyssa E. Johnson

Faculty Publications

Lysosomes are digestive organelles that are crucial for nutrient sensing and metabolism. Lysosome impairment is linked to a broad spectrum of metabolic disorders, underscoring their importance to human health. Thus, lysosomes are an attractive target for metabolic disease therapies. In previous work, we discovered a novel class of tubular lysosomes that are morphologically and functionally distinct from traditionally described vesicular lysosomes. Tubular lysosomes are present in multiple tissues, are broadly conserved from invertebrates to mammals, are more proficient at degrading autophagic cargo than vesicular lysosomes, and delay signs of tissue aging when induced ectopically. Thus, triggering tubular lysosome formation presents …

Background:

Post-term pregnancy, defined as reaching or exceeding 42 + 0 weeks of gestation, is known to be associated with unfavourable birth outcomes. High-income countries have responded to this risk by widely adopting labour induction protocols in late-term, but many low- and middle-income countries have not. However, understanding underlying mechanisms linking post-term births to adverse newborn and infant outcomes remains limited.

Objective:

To investigate the (a) prevalence of post-term, (b) the risk factors associated with post-term (c) the association between post-term births and the risk of small-for-gestational-age (SGA) neonates and of infant mortality in middle-income settings.

A New Error Analysis For Finite Element Methods For Elliptic Neumann Boundary Control Problems With Pointwise Control Constraints, Susanne C. Brenner, Li Yeng Sung

Faculty Publications

We present a new error analysis for finite element methods for a linear-quadratic elliptic optimal control problem with Neumann boundary control and pointwise control constraints. It can be applied to standard finite element methods when the coefficients in the elliptic operator are smooth and also to multiscale finite element methods when the coefficients are rough.
