Introducing The Second-Order Features Adjoint Sensitivity Analysis Methodology For Neural Ordinary Differential Equations—Ii: Illustrative Application To Heat And Energy Transfer In The Nordheim–Fuchs Phenomenological Model For Reactor Safety, Dan Gabriel Cacuci

Faculty Publications

This work presents an illustrative application of the newly developed “Second-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations (2nd-FASAM-NODE)” methodology to determine most efficiently the exact expressions of the first- and second-order sensitivities of NODE decoder responses to the neural net’s underlying parameters (weights and initial conditions). The application of the 2nd-FASAM-NODE methodology will be illustrated using the Nordheim–Fuchs phenomenological model for reactor safety, which describes a short-time self-limiting power transient in a nuclear reactor system having a negative temperature coefficient in which a large amount of reactivity is suddenly inserted. The representative model responses that will …

Introducing The Second-Order Features Adjoint Sensitivity Analysis Methodology For Neural Ordinary Differential Equations—I: Mathematical Framework, Dan Gabriel Cacuci

Faculty Publications

This work introduces the mathematical framework of the novel “First-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations” (1st-FASAM-NODE). The 1st-FASAM-NODE methodology produces and computes most efficiently the exact expressions of all of the first-order sensitivities of NODE-decoder responses with respect to the parameters underlying the NODE’s decoder, hidden layers, and encoder, after having optimized the NODE-net to represent the physical system under consideration. Building on the 1st-FASAM-NODE, this work subsequently introduces the mathematical framework of the novel “Second-Order Features Adjoint Sensitivity Analysis Methodology for Neural Ordinary Differential Equations (2nd-FASAM-NODE)”. The 2nd-FASAM-NODE methodology efficiently computes the exact expressions …

Behind The Screen: Exploring Parental Roles In K-12 Online Education, Barbara T. Sandberg, Charles R. Graham, Jered Borup, Richard E. West, Rocio Quiroga Velasquez

Faculty Publications

Independent engagement can be challenging for K-12 online students. Parents’ physical presence makes them an important source of engagement support. Previous research on parental support in online courses is limited and focused on asynchronous learning within a single program. Since the COVID-19 pandemic, online enrollments have grown and instructional modalities have evolved. To better understand parental support post-Covid, we interviewed 21 parents across eight online programs with asynchronous, synchronous, and bichronous course offerings. Parents identified their affective, behavioral, cognitive, and other support roles. Implications for parental roles in addressing the academic engagement gap are provided to both researchers and practitioners.

Gleaning Rural Journalism: Rural Journalists' Agricultural And Environmental Reporting Utilizing Community Storytelling Networks☆, Jessica Walsh, Mildred F. Perreault, Greg Perreault, Ruth Moon

Faculty Publications

Environmental concerns are growing in parts of the rural United States as drinking water wells become contaminated with agrichemicals, and climate change impacts such as drought and extreme rain events disrupt farming practices. Analyzing in-depth interviews with 29 U.S. rural journalists, we explore the role rural journalists play when reporting on the environment as it relates to agricultural issues. Findings show that reporting about the environment—such as weather, climate change, water shortages, and droughts—appear in rural journalists' stories given those topics' relevance to their rural communities and the social systems forces exerting influence on journalists, yet rural journalists often do …

Detecting N-Phenyl-2-Naphthylamine, L-Arabinose, D-Mannose, L-Phenylalanine, L-Methionine, And D-Trehalose Via Photocurrent Measurement, Feng Li, Ruoxi Yang, Jian Xu, Guohai Xu, Ye Wu

Faculty Publications

The concentration of small molecules reflects the normality of physiological processes in the human body, making the development of simple and efficient detection equipment essential. In this work, inspired by a facile strategy in point-of-care detection, two devices were fabricated to detect small molecules via photocurrent measurement. A linear response of the photocurrent against the concentration of the small molecules was found. In the first device, metal ions were introduced into gel substrates made by xanthan gum to enhance photocurrent response. N-phenyl-2-naphthylamine was measured when iron or manganese ions were used. L-Phenylalanine was measured when the gel was modified by …

Controlling Anti-Asian Conduct On College Campuses: Can Including Ethnic Studies Programs Help?, Hani Morgan

Faculty Publications

The COVID-19 pandemic has triggered hostile acts against Asian college students. One of the ways to respond to these acts is to increase Asian American ethnic studies programs and courses. Although critics argue that ethnic studies cause divisiveness, research indicates that they are beneficial to students from all groups. University administrators may fear implementing these programs because they sometimes associate them with the violence that occurred during the late 1960s when students demanded ethnic studies to be included in the college curriculum. But this to a great extent by the poor representation of racial minority groups in the curriculum and …

Preserving The Future Of Juries And Jury Trials, Paula Hannaford-Agor, Hope Forbush, Miriam Hamilton, Jawwaad Johnson, Morgan Moffett

Faculty Publications

To preserve the future of juries and jury trials, the National Center for State Courts (NCSC) convened a meeting of representatives from a broad array of justice system stakeholders as a project under the Justice for All Reauthorization Act (JFARA). To frame the stakeholder discussions, NCSC employed strategic foresight, a methodological approach designed to explore a range of possible futures of juries and jury trials within the American justice system as a vehicle for identifying critical vulnerabilities within the current jury system and proposing targeted strategies to preserve and strengthen jury trials. Critical vulnerabilities are those areas of weakness that …

Strategic (Non)Disclosure: Activation And Avoidance Of Social Ties Among Women Seeking Abortion, Kathleen Broussard

Faculty Publications

The increased politicization of sexual and reproductive health has created barriers to medically necessary care. In absence of formal health care, social ties become critical sources of information and resources, yet the disclosure of stigmatized health needs carries significant risk. How do people navigate the risks and benefits of disclosure when seeking care for stigmatized needs? Drawing on original survey data (N = 153) and in-depth interviews (N = 55) with women who attempted a self-managed abortion, I first describe the distinct roles of weak and strong ties in women’s health-seeking experiences. I then demonstrate how both partial disclosure and …

Law And Equity On Appeal, Aaron-Andrew P. Bruhl

Faculty Publications

Most lawyers know that the Federal Rules of Civil Procedure merged the divergent trial procedures of the common law and of equity, but fewer are familiar with the development of federal appellate procedure. Here too there is a story of the merger of two distinct systems. At common law, a reviewing court examined the record for errors of law after the final trial judgment. In the equity tradition, an appeal was a rehearing of the law and the facts that aimed at achieving justice and did not need to await a final judgment. Unlike the story of federal trial procedure, …

Roman History In Sibylline Oracle 13: A Palestinian Jewish Perspective On Emperors, Usurpers, And Saviors During The Third Century Ce (Part One: From Maximus I “Thrax” To Philip I “The Arab”), Kenneth Atkinson

Faculty Publications

The period commonly known as the “Crisis of the Third Century” (235-284 CE) began with the assassination of the Roman emperor Severus Alexander (222-235 CE), the last ruler of the Severan dynasty. This turbulent era was marked by nearly fifty years of civil war, barbarian invasions, rebellions, and political and social unrest caused by approximately twenty-six claimants to the imperial throne. Although the end of this age of disorder under Diocletian (284-305 CE) is well-known, we have little information about much of the third century CE, particularly its first decades. This study examines book 13 of the Sibylline oracles, which …

The Relationship Between A Transient Scientific Phenomenon And Local Journalism At The Beginning Of The Gilded Age, Thomas Hockey

Faculty Publications

In the United States, the nineteenth century was the halcyon era for local newspapers. These publications were the primary source of public information at a time when other periodicals and books had low circulation. The purpose of this paper is to explore how local journalism in the nineteenth-century United States dealt with an occasion outside the boundaries of the commonplace: an unfamiliar natural phenomenon. My example is the total solar eclipse of 7 August 1869. Editors and journalists of the time largely were unaccustomed to covering celestial events. Nevertheless, they sensed—correctly—an interest in the solar eclipse. Articles about the approaching …

Redressing Judicial Misbehavior: An Integrated Approach To Judicial Immunity, Nancy Amoury Combs

Faculty Publications

Immunities generate intense public interest and controversy. Whether it is the sweeping presidential immunity that former President Trump has claimed or the qualified immunity that rogue police invoke to evade financial responsibility for their brutality, immunities stand as a highly contested aspect of the American legal system. Judicial immunity incites similar controversy. American judges possess absolute immunity from civil suits for their judicial acts, so victims are barred from seeking civil compensation, even against judges who engage in purposeful or malicious misconduct from the bench. For decades scholars have sought to curtail absolute judicial immunity, but they have overlooked a …

Human Capital Assessment In Indigenous Regions To Enable Sustainable Futures, Victoria N. Sharakhmatova, Elena G. Mikhailova

Faculty Publications

This study is dedicated to the economic valuation of human capital (HC) in the regions where the Indigenous peoples of Kamchatka reside. The entire Kamchatksky Krai is considered an Indigenous people’s ancestral territory. However, in this study, only municipalities whose population is more than one-third Indigenous were chosen for the assessment. This includes six municipal districts and one urban district (Aleytsky, Bystrinsky, Karaginsky, Olyutorsky, Penzhinsky, and Tigilsky municipal districts and Palana urban district). The study employs statistical analysis and integrated, situational approaches: the investment approach was deemed the most appropriate tool for the economic assessment of HC in Indigenous territories. …

Motivational Dysregulation With Melanocortin 4 Receptor Haploinsufficiency, Alex M. Steiner, Robert F. Roscoe, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Obesity, by any standard, is a global health crisis. Both genetic and dietary contributions to the development and maintenance of obesity were integral factors of our experimental design. As mutations of the melanocortin 4 receptors (MC4R) are the leading monogenetic cause of obesity, MC4R haploinsufficient rats were fed a range of dietary fat (0–12 %) in a longitudinal design. Physiological and motivational assessments were performed using a locomotor task, a 5-choice sucrose preference task, an operant task with fixed and progressive ratios, as well as a distraction operant task. Dendritic spine morphology of medium spiny neurons (MSNs) of the nucleus …

The Suppression Of Ocean Waves By Biogenic Slicks, Nathan J. M. Laxague, Christopher Zappa, Shantanu Soumya, Oliver Wurl

Faculty Publications

Surface waves are significantly damped by biogenic surfactants which accumulate at the ocean's surface from the high latitudes to the tropics. The growth, development, and breaking of short wind-driven surface waves is a key mediator of the air-sea exchange of momentum, heat, and trace gases consequently, the effect of surfactant compounds in the uppermost millimeters of the ocean in damping short surface waves bears on earth's climatic processes. The mechanisms through which surfactants suppress waves have been studied in great detail through careful laboratory experimentation in quasi one-dimensional wave tanks. However, the spatial scales over which this damping occurs in …

Inferring Tlb Configuration With Performance Tools, Cristian Agredo, Tor J. Langehaug, Scott R. Graham

Faculty Publications

Modern computing systems are primarily designed for maximum performance, which inadvertently introduces vulnerabilities at the micro-architecture level. While cache side-channel analysis has received significant attention, other Central Processing Units (CPUs) components like the Translation Lookaside Buffer (TLB) can also be exploited to leak sensitive information. This paper focuses on the TLB, a micro-architecture component that is vulnerable to side-channel attacks. Despite the coarse granularity at the page level, advancements in tools and techniques have made TLB information leakage feasible. The primary goal of this study is not to demonstrate the potential for information leakage from the TLB but to establish …

From "Open Ocean" To "Exposed Aquaculture": Why And How We Are Changing The Standard Terminology Describing "Offshore Aquaculture", Tyler Sclodnick, Michael Chambers, Barry Antonio Costa-Pierce, Tobias Dewhurst, Nils Goseberg, Kevin Gerald Heasman, Wolf Isbert, Gesche Krause, Daniel Wieczorek, Till Markus, Bela H. Buck

Faculty Publications

The term “offshore” with regards to aquaculture has hitherto encompassed various perspectives, including technology, geographic location, legal jurisdiction, and more. To resolve the ambiguity in this term and understand its implications for current and future aquaculture development, “offshore” should be resolved into two separate metrics: distance from shore and energy exposure. The United Nations Convention on the Law of the Sea (UNCLOS) distinguishes between internal waters, territorial sea, contiguous zone, exclusive economic zone (EEZ), and the high seas, but currently has no precise definition for “offshore” in its provisions, and therefore no applicable laws pertaining to “offshore” aquaculture. Regulating a …

Master Narratives Surrounding Rural Emerging Adult Migration: Resources For Postsecondary Decision-Making In Rural Communities, Cindy Hartman, Jayson Seaman, Andrew D. Coppens, Erin H. Sharp, Sarah Jusseaume

Faculty Publications

This study examined the cultural messages informing postsecondary decision-making processes surrounding emerging adult migration from/to a predominately rural state in the northeastern U.S. Utilizing an ecological approach to sampling, this study used 27 interviews and 5 focus groups of stakeholders working in educational, employment, and quality of life sectors. Narrative analysis yielded evidence of a predominant master narrative of migration as a developmental requirement during emerging adulthood. Stakeholders spoke of normative and prescriptive expectations that emerging adults particularly in rural areas orient their plans and decision-making around, including leaving their home communities for developmental reasons. Implications for emerging adult development …

Short Communication: Numerically Simulated Time To Steady State Is Not A Reliable Measure Of Landscape Response Time, Nicole M. Gasparini, Adam M. Forte, Katherine R. Barnhart

Faculty Publications

Quantifying the timescales over which landscapes evolve is critical for understanding past and future environmental change. Computational landscape evolution models are one tool among many that have been used in this pursuit. We compare numerically modeled times to reach steady state for a landscape adjusting to an increase in rock uplift rate. We use three different numerical modeling libraries and explore the impact of time step, grid type, numerical method for solving the erosion equation, and metric for quantifying the time to steady state. We find that modeled time to steady state is impacted by all of these variables. Time …

Bostock And The Forgotten Eeoc, Sandra F. Sperino

Faculty Publications

In Bostock v. Clayton County, Georgia, the Supreme Court formally recognized that federal discrimination law prohibits discrimination based on sexual orientation and gender identity. The opinion barely mentioned the Equal Employment Opportunity Commission (EEOC), the federal agency charged with enforcing federal discrimination law. Reading Bostock, it would be easy to get the impression that the EEOC played little to no role in the outcome. This Essay reclaims and restores the EEOC's role.

In restoring the EEOC's role in this story, two themes emerge. First, Bostock's methodology erases the administrative agency tasked with enforcing Title VII in ways that are inconsistent …

Online Eye Tracking For Aphasia: A Feasibility Study Comparing Web And Lab Tracking And Implications For Clinical Use, Willem S. Van Boxtel, Michael Linge, Rylee Manning, Lily N. Haven, Jiyeon Lee

Faculty Publications

Background & Aims: Studies using eye-tracking methodology have made important contributions to the study of language disorders such as aphasia. Nevertheless, in clinical groups especially, eye-tracking studies often include small sample sizes, limiting the generalizability of reported findings. Online, webcam-based tracking offers a potential solution to this issue, but web-based tracking has not been compared with in-lab tracking in past studies and has never been attempted in groups with language impairments. Materials & Methods: Patients with post-stroke aphasia (n = 16) and age-matched controls (n = 16) completed identical sentence-picture matching tasks in the lab (using an EyeLink system) and …

Historic Breeding Practices Contribute To Germplasm Divergence In Leaf Specialized Metabolism And Ecophysiology In Cultivated Sunflower (Helianthus Annuus), Jordan A. Dowell, Alan W. Bowsher, Amna Jamshad, Rahul Shah, John M. Burke, Lisa A. Donovan, Chase M. Mason

Faculty Publications

Premise: The use of hybrid breeding systems to increase crop yields has been the cornerstone of modern agriculture and is exemplified in the breeding and improvement of cultivated sunflower (Helianthus annuus). However, it is poorly understood what effect supporting separate breeding pools in such systems, combined with continued selection for yield, may have on leaf ecophysiology and specialized metabolite variation. Methods: We analyzed 288 lines of cultivated H. annuus to examine the genomic basis of several specialized metabolites and agronomically important traits across major heterotic groups. Results: Heterotic group identity supports phenotypic divergences between fertility restoring and cytoplasmic male-sterility maintainer …

Combined Toxicity Of Multi-Walled Carbon Nanotubes And Cu2+ On The Growth Of Ryegrass: Effect Of Surface Modification, Dose, And Exposure Time Pattern, Wenwen Xie, Cheng Peng, Weiping Wang, Xiaoyi Chen, Jiaqi Tan, Wei Zhang

Faculty Publications

The escalating release of multi-walled carbon nanotubes (MWCNTs) into the environment has raised concerns due to their potential ecotoxicological impacts. However, their combined phytotoxicity with heavy metals such as copper (Cu) is still unclear. This study investigated the individual and combined toxic effects of MWCNTs (MWCNT, MWCNT-OH, and MWCNT-COOH) and Cu²⁺ on ryegrass (Lolium multiflorum), uniquely considering different addition orders. The results show that Cu severely inhibited the growth of ryegrass while MWCNTs exhibited a hormesis effect on ryegrass. When MWCNT and Cu were combined, the malondialdehyde (MDA) content in ryegrass showed a 32.39% increase at 20 mg/L MWCNT …
