Development Of An Access Charge Framework For High-Speed Rail Incorporating Rail Replacement Costs And Dynamic Train Characteristics, Nitesh Kumar Yadav

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis develops a framework to determine track access charges for shared high-speed rail corridors, with a focus on rail replacement cost driven by train-induced loads. The method explicitly accounts for both static loads, resulting from axle weights, and dynamic loads that arise from train speed and track geometry, particularly curvature. Train characteristics such as axle load, operating speed, frequency of service, and number of wheels are integrated with track parameters, including curve radius, to calculate the total vertical load. These loads are used to estimate the cumulative tonnage threshold for rail replacement and the resulting service life of the …

The Effectiveness Of Kolmogorov–Arnold Networks In The Healthcare Domain, Vishnu S. Pendyala, Nivedita Venkatachalam

Faculty Research, Scholarly, and Creative Activity

Kolmogorov–Arnold Networks (KANs) have recently emerged as a powerful alternative to traditional Artificial Neural Networks (ANNs), offering superior accuracy and interpretability, which are two critical requirements in healthcare applications. This study investigates the effectiveness of KANs across a range of clinical tasks by applying them to diverse medical datasets, including structured clinical data and time-series physiological signals. Compared with conventional ANNs, KANs demonstrate significantly improved performance, achieving higher predictive accuracy even with smaller network architectures. Beyond performance gains, KANs offer a unique advantage: the ability to extract symbolic expressions from learned functions, enabling transparent, human-interpretable models—a key factor in clinical …

Analyzing Food Access: An Investigation Of Food Insecurity Amongst Latinos In Rural Nebraska, Natalia Santos

Theses & Dissertations

Background: Food insecurity is a public health issue in the United States, with disproportionately higher rates among Latino/Hispanic households. Rural communities face unique geographical, socioeconomic, and systemic barriers that often exacerbate food access disparities. Despite the growing Latino population in rural areas, particularly in Midwestern states like Nebraska, there remains a critical gap in comprehensive research that integrates both objective and subjective understandings of their food environments. Understanding these multifaceted influences is crucial for developing effective, culturally sensitive interventions.

Problem Statement: This dissertation aims to answer the central question: How does food access and food insecurity manifest amongst Latinos in …

Diverse Cell Types Establish A Pathogenic Immune Environment In Peripheral Neuropathy, Julie Choi

Arts & Sciences Graduate Student Theses and Dissertations

Neuroinflammation plays a complex and context-dependent role in many neurodegenerative diseases. We identified a key pathogenic function of macrophages in a mouse model of a rare human congenital neuropathy in which SARM1, the central executioner of axon degeneration, is activated by hypomorphic mutations in the axon survival factor NMNAT2. Macrophage depletion blocked and reversed neuropathic phenotypes in this sarmopathy model, revealing SARM1-dependent neuroimmune mechanisms as key drivers of disease pathogenesis. In this study, we investigated the impact of chronic subacute SARM1 activation on the peripheral nerve milieu using single cell/nucleus RNA-sequencing (sc/snRNA-seq). Our analyses reveal an expansion of immune cells …

Multimodal Characterization Of Systems-Level Robustness In The Cellular Organelle Network, Aline Arra

Arts & Sciences Graduate Student Theses and Dissertations

Eukaryotic cells house mesoscopic and macroscopic complex systems that work in tandem for proper cellular function. A defining feature of eukaryotic cells is their mesoscopic network of membrane bound compartments called organelles. While each type of organelle has their own individual functions, there are vital cellular processes that come from the interactions between them, such as organelle biogenesis and metabolic regulation. A central question in cellular biophysics is to what degree is cellular function robust or fragile to breaks in the organelle network. These interactions can be explored by genetically deleting inter-organelle protein tethers called organelle contact sites. Here we …

Unveiling Mysteries Of The Universe: Axions, Sterile Neutrinos, And Curvatons, Takuya Okawa

Arts & Sciences Graduate Student Theses and Dissertations

The Standard Model of particle physics and cosmology is amazingly successful in describing our universe, from at present to even tracing back to just one second after its birth. Yet, it is known to be incomplete. For instance, (i) more than four-fifths of matter in the universe is unknown, (ii) quantum chromodynamics is unnaturally of CP-preserving nature, (iii) the universe produced baryonic particles by nearly equal but slightly larger amount compared to anti-baryonic particles, and (iv) the physics at very early times is not understood yet. This thesis first briefly summarizes the Standard Model of particle physics and cosmology, and …

Red Noise Suppression In Pulsar Timing Array Data Using Adaptive Splines, Yi-Qian Qian, Yan Wang, Soumya Mohanty

Physics & Astronomy Faculty Publications

Noise in Pulsar Timing Array (PTA) data is commonly modeled as a mixture of white and red noise components. While the former is related to the receivers, and easily characterized by three parameters (EFAC, EQUAD and ECORR), the latter arises from a mix of hard to model sources and, potentially, a stochastic gravitational wave background (GWB). Since their frequency ranges overlap, GWB search methods must model the non-GWB red noise component in PTA data explicitly, typically as a set of mutually independent Gaussian stationary processes having power-law power spectral densities. However, in searches for continuous wave (CW) signals from resolvable …

Lipidomic And Proteomic Insights From Extracellular Vesicles In The Postmortem Dorsolateral Prefrontal Cortex Reveal Substance Use Disorder-Induced Brain Changes, Chioma M Okeoma, Wasifa Naushad, Bryson C Okeoma, Carlos Gartner, Yulica Santos-Ortega, Savio Lima-Bastos, Martin R Larsen, Alessio Noghero, Consuelo Walss-Bass, Rodrigo Grassi-Oliveira

Substance use disorder (SUD) significantly increases the risk of neurotoxicity, inflammation, oxidative stress, and impaired neuroplasticity. The activation of inflammatory pathways by substances may lead to reactive astrogliosis and chronic neuroinflammation, potentially mediated by the release of extracellular particles (EPs), such as extracellular condensates (ECs) and extracellular vesicles (EVs). These particles, which reflect the physiological, pathophysiological, and metabolic states of their cells of origin, might carry molecular signatures indicative of SUD. In particular, our study investigated neuroinflammatory signatures in SUD patients by isolating EVs from the dorsolateral prefrontal cortex (dlPFC) Brodmann's area 9 (BA9) from postmortem subjects. We isolated BA9-derived …

Faculty, Staff and Student Publications

The gut microbiome has emerged as a key regulator of response to cancer immunotherapy. However, a better understanding of the underlying mechanisms by which the microbiome influences immunotherapy is needed to identify strategies to optimize outcomes. To this end, we developed a mathematical model to obtain insights into the effect of the microbiome on the immune system and immunotherapy response. This model was based on (i) gut microbiome data derived from preclinical studies, (ii) mathematical modeling of the antitumor immune response, (iii) association analysis of microbiome profiles with model-predicted immune profiles, and (iv) statistical models that correlate model parameters with …

"Please Hold Space For Them": The Role Of Mental Health Professionals In Supporting Bipoc Female Survivors Of Campus Sexual Assault, Brianna Josefine Ortega

Doctoral Dissertations

Campus sexual assault (CSA) remains a pervasive issue in the United States, disproportionately affecting women. Despite this, the experiences of Black, Indigenous, and other Persons of Color (BIPOC) women are often underrepresented in the literature, limiting understanding of how best to support them. Based on intersectionality theory, this qualitative study explores how mental health professionals (MHPs) support BIPOC female survivors of CSA. Semi-structured interviews were conducted with six MHPs, and a thematic analysis framework uncovered seven key themes: disclosure (subtheme: barriers to disclosure), impacts of campus culture, fear and distrust, impact of campus sexual assault, coping, resources available for survivors, …

Pedagogy Of Dialogic Communication: Becoming Aware Of Our Unconscious Belief, Leonard J. Shedletsky

International Journal of Transformative Teaching and Learning in Higher Education

Norms of the classroom limit our learning about ourselves. Hidden scripts guide our behavior. Beliefs we are unaware of are often behind our responses to ideas. Unconscious beliefs are connected to our immediate, spontaneous responses, referred to as intuitions in social intuitionist theory. Intuition is what we believe and can access at high speed without being aware of what we believe, without being aware of our reasons for believing it, and without knowing how we came to this belief or how we access it in memory. We experience intuitions as knowing something all at once. We know what we like, …

Exploring The Connection Between Teaching Frameworks And Policies For Assessing Teaching, Barbara J. Bird, Beate Brunow, Eric Kyle, Shawn R. Simonson

International Journal of Transformative Teaching and Learning in Higher Education

Most faculty policies aimed at faculty review or assessment of teaching do not include specific teaching criteria and standards but instead lean heavily on student evaluations and peer review of teaching. This approach provides no concrete path for using assessment in a feedback loop that enables teachers to improve teaching. Implementing teaching frameworks can improve feedback loops and assessment policies by providing specific criteria and standards. Developing teaching effectiveness frameworks and connecting them to teaching assessment policies can be a critical step in advancing institutional change initiatives focused on teaching effectiveness. This critical alignment enables sustainable and meaningful change. This …

Rooted In Resilience: Exploring Indigenous Economic Models And Sustainability On The Rocky Boy Indian Reservation., Dominique Nault

Capstone Collection

This study examines how traditional practices and cultural values of the Chippewa Cree shape the economic identity and sustainability of the Rocky Boy Indian Reservation. Using a mixed-methods approach that combined demographic surveys with culturally grounded interviews, the research reveals that economic development in the community is inseparable from traditional knowledge systems, collective well-being, and ecological stewardship. Rather than centering on financial accumulations, wealth is defined by family, community, and cultural continuity, placing traditional knowledge on par with land and monetary resources.

Three central themes emerged from the data: (1) the enduring role of traditional values and cultural knowledge in …

Exploring Identity And Seeking Belonging: Diverse Students’ Experiences With A Campus Women’S Center, Sarah Tucker Jenkins

Journal for Women and Gender Centers in Higher Education

Women’s and gender equity centers (abbreviated as women’s centers) were first established in U.S. universities in the 1960s and currently number in the multiple hundreds across all types of higher education institutions in the country. Women’s centers play a vital role in providing high impact, culturally responsive student engagement; however, research on women’s centers is often informal and infrequent, leading to a dearth of knowledge about the efficacy of student engagement efforts. Women’s centers, and the feminist movement from which they arose, have historically excluded the voices and experiences of women of color and other marginalized identities. While centers are …
