A Delayed Siamr Prostate Cancer Model With Vertical Transmission And Treatment: Stability Analysis And Numerical Simulation, Hüseyi̇n Demir, İnci̇ Çi̇li̇ngi̇r Süngü, İbrahi̇m Keles

Turkish Journal of Mathematics

​In this paper, we propose and analyse a delayed-compartmental mathematical model of prostate cancer dynamics that incorporates vertical transmission and therapeutic intervention. The population is stratified into five compartments: susceptible (S), infected/virally activated (I), asymptomatic infectious under treatment (A), malignant untreated (M), and recovered (R). A discrete time delay τ > 0 is introduced in the force-of-infection term to model the age-dependent onset of susceptibility in middle-aged adult males. Vertical transmission of viral etiology at a rate qΛ ensures that a fraction of newborns enter the infected compartment directly, rendering the disease persistent regardless of the basic reproduction number R₀. We …

​Compact And Am-Compact Orthogonally Additive Operators, Bahri̇ Turan, Bi̇rol Altin

Turkish Journal of Mathematics

We show that compactness of orthogonally additive operators between Banach lattices is not preserved under taking the modulus by providing a nonlinear analogue of Krengel’s example. In contrast, for operators acting from a Banach lattice into an AM-space, AM-compactness is stable under lattice operations. Moreover, the space of absolutely norm bounded AM-compactorthogonally additive operators from a Banach lattice into an AM-space is a Banach lattice, and on such AM-spaces with the weak Fatou property, norm boundedness coincides with absolute norm boundedness.

Hyers-Ulam And Hyers-Ulam Rassias Stability Of Caputo Fractional Hahn Difference Equations, Karima Mohamed Oraby, Alaa E. Hamza, Afrah Al-Bossly

Turkish Journal of Mathematics

​In this paper, we investigate Hyers–Ulam and Hyers–Ulam–Rassias stability for fractional linear Hahn difference equations of Caputo Type. To the best of our knowledge, this is the first work concerning Hyers–Ulam type stability in the framework of Caputo fractional Hahn difference equations, thereby filling a significant gap in the literature on fractional stability theory. Our approach is based on establishing an equivalence between the fractional Hahn difference initial value problem and a corresponding fractional integral equation, via the Caputo–Hahn inversion formula. These results lay a strong groundwork for analyzing the stability of Hahn fractional systems, which could be useful in …

The Influence Of Childhood Experiential History On U.S. Vice President Jd Vance’S Personality, Amelia Brower, Aubrey Immelman

Psychology Faculty Publications

This paper presents the results of a developmental causal analysis of the adult personality of U.S. vice president JD Vance, from the conceptual perspective of personologist Theodore Millon.

Psychodiagnostically relevant data relating to Vance’s personality were collected from biographical sources and media reports and synthesized into a personality profile using the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with DSM-III-R, DSM-IV, and DSM-5-TR.

The findings of the personality assessment were previously reported in a separate paper. Vance’s primary personality patterns were found to be Dominant/controlling and Ambitious/confident, supplemented by …

Directing The Absent Tool: Friction Embodiment And Competency Progression In Ai Assisted Creative Learning, Daniel Suarez, James Hutson

Faculty Scholarship

Generative artificial intelligence complicates the relationship between successful creative production and the development of independent disciplinary judgment. Task allocation offers a practical response by identifying operations that learners should protect, perform with support, or delegate, yet the educational value of an allocation depends on conditions that change beyond a single assignment. This article extends a process-centered framework along three connected axes: absence, modality, and time. Constructivist friction describes difficulty encountered when learners must reconstruct judgments previously supplied by an available tool; its educational value depends on subsequent diagnosis, feedback, and transfer rather than difficulty alone. A spatial and embodied extension …

¿Digno Retorno? De La Ciudadanía Cultural A La Ciudadanía Truncada En El Retorno A México, Nancy Plankey-Videla, Luz E. Herrera

Faculty Scholarship

The chapter revisits citizenship by drawing on the findings of the Mexican Reintegration Project that interviewed 333 Mexicans that the U.S. deported or who returned to Mexico, and 18 civil society organizations that were part of the study. Many Mexicans in the United States experience a form of belonging, or cultural citizenship, even while being monitored by immigration and law enforcement. Upon returning to Mexico —whether forcibly or “voluntarily” - they experience a truncated citizenship that also complicates their sense of belonging to their own country of origin. They often do not have all the documentation needed to prove their …

Hyman

Student Publications [Scholarly]

Background and Hypothesis: Schizophrenia spectrum disorders (SSDs) produce severe symptoms, disability, and premature mortality, but only partially effective symptomatic treatments exist. Treatment development is impeded by lack of insight into disease mechanisms or objective biomarkers for clinical trials. Advances in genetics and neurobiology have converged on strong pathogenic hypotheses for SSDs centered on synapse dysfunction and excessive pruning, pathogenic processes that may produce measurable proteomic evidence in cerebrospinal fluid (CSF). Leveraging design precedents from successful fluid biomarkers discovery for Alzheimer’s disease, we undertook a pilot study to test the feasibility of repeated CSF and blood samples collection from individuals with …

Review: Advancements In Fibrous Aerosol Filtration Across Experimental Analysis, Numerical Modeling, And Fabrication Technologies, Mirza Muhammad Zaid, Ashish Ranjan Kumar, Ashish Kakoria, Lina Zheng, Guang Xu

Mining Engineering Faculty Research & Creative Works

The increasing incidence of aerosol-related pulmonary diseases has intensified the need for efficient fibrous filtration technologies capable of capturing ultrafine particles with low pressure drop. Although nonwoven fibrous filters are widely used in medical, industrial, and ventilation systems, their complex internal structures and multiscale transport mechanisms remain insufficiently understood. This review examines the theoretical foundations of aerosol filtration, including single-fiber capture mechanisms and the concept of the most penetrating particle size. In addition, electrostatic interactions, including charge generation, transport, and stability, are incorporated to extend conventional mechanical filtration frameworks. Particular attention is given to flow–particle interactions within fibrous media. We …

Matheson, Sandra Amaral, Ckid Investigators

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Slower chronic kidney disease (CKD) progression allows more time for transplant preparation. Whether differences in CKD progression by race/ethnicity associate with preemptive or living donor transplantation in youth has not been well studied.

METHODS: We examined the association between time spent with low eGFR (between 10-30 mL/min/1.73 m²) and odds of preemptive or living donor transplantation among youth with CKD. eGFR was estimated using the bedside Schwartz (if < 18 years) and CKD-EPI 2021 equations (if ≥ 18 years) and the CKiD U25 equation in sensitivity analysis. Time spent with low eGFR was compared by race/ethnicity.

RESULTS: Among 333 youth with CKD (median age 11 years [IQR 7,14]), median time spent with low eGFR was 28.8 months. 77% were preemptively waitlisted, and 45% received preemptive …

This analysis is based in the typology proposed by Petrić in her 2007 article, slightly modified for the purpose of the present …

Connected But Disconnected: A Covid-19 Youth Participatory Action Research Study, Vianney Atugonza, Jodi Dworkin, Stacey S. Horn, Joanna A. Tzenis, Samantha Lebouef

Journal of Youth Development

In 2020, the COVID-19 pandemic forced most schools across the U.S. to close and transition to remote learning. Families were forced to transform their homes into classrooms while facing challenges to their health, finances, and social connections. To better understand how young people experienced these changes, a Youth Participatory Action Research (YPAR) project was employed to engage young people in naming, exploring, and sharing their experiences during this time. Nine high school youth leaders were trained as researchers to conduct interviews with their peers. These youth scholars were also trained on how to code, sort, and disseminate data and results. …

Exploring 21st-Century Skills In A Summer Camp: A Qualitative Methodological Triangulation Approach, Alexander Bowman, Jing Song

Journal of Youth Development

Despite the recognized importance of 21st-century skills and the substantial body of research on these skills, little is known about how to identify growth in these skills. The lack of reliable methods to measure 21st-century skill growth presents a challenge for the design of relevant learning environments and for evaluating if such learning environments are effective. Using a qualitative methodological triangulation approach, this study explored camp counselors’ learning processes. Using a systematic data integration method, field observations were synthesized with participant reflections about how their skills develop. Data were collected from 13 high-school-aged junior camp counselors at a summer camp …

Becoming Who I Am: How Youth Leadership Experiences Shape Lifelong Leadership Journeys, Dustin Evatt, Deborah Acker, Parker R. Watson, Jennifer T. Peters

Journal of Youth Development

Youth leadership experiences have the power to shape individuals’ values, identities, and leadership behaviors well into adulthood, yet limited empirical research has examined how these formative experiences contribute to leadership development over time. This study examines the long-term impact of youth leadership experiences using the six-stage Leadership Identity Development (LID) model as a guiding and interpretive framework by exploring the journeys of alumni from the Shelton Challenge, a six-day immersive high school leadership program at NC State University rooted in values-based and positive youth development (PYD) principles. Using narrative inquiry, we conducted interviews and focus groups with 30 alumni ages …

A More Perfect Union: An Examination Of The Film, Salt Of The Earth, And The American Labor Movement, Amber Montgomery

Say Something Theological: The Student Journal of Theological Studies

This paper examines the film, Salt of the Earth, which is based on the actual events of the Mine-Mill strike that took place in Hanover, New Mexico, in 1949. The strike was organized by Mexican workers with the help of their wives. The fight was over workers’ rights, as well as their dignity. At the same time, another fight was taking place. The wives of these miners were also seeking equality within their marriages, serving as a parallel narrative to the strike. To understand the environment at this time, this paper will also analyze American politics during this period, …

Evaluating The Case Against Fda Independence, Patricia J. Zettler, Rachel E. Sachs

Utah Law Review

Many former FDA officials, both politically-appointed leaders and those from the career ranks, as well as numerous FDA scholars have advocated for increased FDA independence in varied forms, and for good reason. At the same time, there are advantages to FDA’s current structure, and there may be ways to insulate career scientific experts’ decisions from political influence and to address other problems by generating independence, without overhauling the agency’s design. Policymakers should consider all options, as particular independence features may, or may not, be the best way, to address concerns about FDA’s capacity to carry out its vital public health …

Fda In 2050: Best- And Worst-Case Scenarios, Michael S. Sinha

Utah Law Review

In 2025, the Trump administration disrupted many critical aspects of the biomedical research infrastructure in the United States. The Food and Drug Administration (FDA) was not spared. Robert F. Kennedy, Jr., a known vaccine denier with no health care experience, was confirmed as Secretary of the U.S. Department of Health and Human Services (HHS) in February 2025, followed by the confirmation of Dr. Martin Makary as Commissioner of the FDA in April. Departures of long-time FDA scientists, coupled with appointments of key personnel, seemingly because of their public stances on COVID-19 mRNA vaccines, have resulted in a tumultuous year for …

A Primer Of Medical Device Regulation: How To Go From Reactive To Proactive To Better Protect Patient Safety, Sneha Dave, Rita F. Redberg

Utah Law Review

FDA oversight of medical devices has too often been reactive, following preventable disasters rather than based on a proactive commitment to patient safety. The history of the device framework, the expansion of expedited pathways, weak postmarket surveillance, broad preemption, and conflicted patient advocacy together create a perfect storm of a regulatory environment that tolerates uncertainty and externalizes costs onto patients. Reforms such as time‑limited breakthrough status, mandatory and enforceable postmarket studies, requirements for more robust safety and efficacy data, and strengthened reporting duty for clinicians would move device regulation closer to FDA’s statutory mandate to protect public health. It would …

Fda Policymaking In The Trump Deregulation Era, Jordan Paradise J.D.

Utah Law Review

This Article endeavors to contribute to and continue the conversation about how the Trump deregulatory agenda is impacting a vital national public health agency, the FDA, and our national collective public health in ways that deviate from longstanding agency policy and practice. Various other FDA policy actions deserve concerted attention by legal scholars, including the agency’s recent moves in the direct-to-consumer marketing (DTC) drug space through targeted warning letters and publicity about reforming the “adequate provision” standards, food additives and generally recognized as safe (GRAS) listing processes and directives to industry, adjustments to the biosimilar interchangeability requirements through guidance document, …

Medical Device Regulation: We Can’T Just Go Back (Nor Should We), George Horvath

Utah Law Review

For much of the twentieth century, the federal Food and Drug Administration maintained its reputation as the preeminent regulatory agency, renowned for providing vigilant and scientifically rigorous oversight that ensured the safety and effectiveness of drugs and medical devices. But a former FDA commissioner recently lamented that “[t]he FDA as we’ve known it is finished.” Many commentators have raised concerns that reductions in force will leave the Agency understaffed, that these shortages will prolong review times, and that the standards applied to premarket evaluations of medical products will allow unsafe and ineffective products to reach the market. But in the …

Post-Approval Problems, Anjali D. Deshmukh M.D., J.D.

Utah Law Review

Sitting across from 4-year-old Jessica’s parents, I whispered the truth: the most promising drug to fight their daughter’s disease was a therapy approved for adults, not for children her age. We could estimate the dose, monitor her organs, and hope the toxicity would not outpace the benefits, but there was no high-quality clinical trial data proving it was safe for kids like her yet, despite congressional mandates. Unexpected safety issues are often identified after drugs are approved and used outside of a closely controlled clinical trial, especially in understudied populations like children, the elderly, and pregnant women. When I asked …
