Amino Acid Pet Tracers For Cancer Imaging And Response Assessment, Ugur Akca

ETDs from 2020-2029

Triple-negative breast cancer (TNBC) and high-grade glioma (HGG) pose significant diagnostic and therapeutic challenges due to their aggressive biology and the limitations of [¹⁸F]FDG PET, which suffers from nonspecific uptake in inflammatory tissues, complicating differentiation of viable tumor from treatment-related effects. Computed Tomography, while strong for structural changes, has limited soft tissue contrast for distinguishing tumor from inflammation, and Magnetic Resonance Imaging, despite superior soft tissue resolution, struggles with differentiating active tumor from post-treatment changes like edema or necrosis due to nonspecific enhancement. These challenges highlight the necessity for complementary and advanced imaging strategies for improved diagnosis and monitoring. This …

Physiological And Neuroimmune Effects Of Manual Therapy, Murdi S. Alanazi

ETDs from 2020-2029

Manual therapy (MT) is widely used across healthcare disciplines for the management of musculoskeletal conditions. Emerging evidence indicates that MT may also influence broader physiological systems such as the nervous and the immune systems. However, the mechanisms underlying these effects are still not well understood, and limited evidence exists regarding the neuroimmune effect of MT in neurologically impaired populations such as multiple sclerosis (MS). The overall aim of this dissertation was to investigate the physiological effects of MT, synthesizing current evidence across mechanistic domains, and generating pilot data to inform future research. This dissertation was structured around four manuscripts. The …

Recurrence Of Locally Perturbed Random Walks With Long Jumps, Tamer Oraby, András Telcs

School of Mathematical & Statistical Sciences Faculty Publications

We study the effect of local perturbations on the recurrence of random walks with long jumps. Such walks serve as discrete models for infinite-horizon Lorentz processes, in which a particle can take arbitrarily long steps in specific directions. Motivated by a question of Sinai in the finite-horizon case and its extension by Szász to the infinite-horizon setting, we give recurrence and transience criteria for long-jump walks on Z2 and certain classes of graphs, and we prove that local perturbations in a bounded region do not change the recurrence property. Our proofs combine the Markov chain approach with the electrical network …

Hybrid Quantum-Classical Optimization Of The Resource Scheduling Problem, Tyler Christeson, Md Habib Ullah, Ali Arabnya, Amin Khodaei, Rui Fan

Electrical and Computer Engineering: Faculty Scholarship

Resource scheduling is critical in many industries, especially in power systems where the Unit Commitment (UC) problem determines the on/off status and output levels of generators under physical and economic constraints. Traditional exact methods, such as Branch-and-Bound, Branch-and-Cut, dynamic programming and mixed-integer linear programming (MILP), remain the backbone of UC solution techniques, but they often rely on linear approximations or exhaustive search, leading to high computational burdens as system size grows. Metaheuristic approaches, such as genetic algorithms, particle swarm optimization, and other evolutionary methods, have been explored to mitigate this complexity; however, they typically lack optimality guarantees, exhibit sensitivity to …

Bankruptcy Judging After Williamson, Vincent S.J. Buccola

BYU Law Review

This Essay asks how bankruptcy judges ought to orient their substantial, statutory discretion in business reorganization cases. The motivating observation is that bankruptcy law enacts a kind of forced integration of productive assets. To shed light on the contemporary problems that bankruptcy judges face, I thus look to two classic approaches to the economic theory of the firm—from Oliver Williamson and from Oliver Hart. I conclude that nonjudicial institutions have largely surmounted the problems to which their theories point, leaving a different, and probably narrower, set of issues to worry about. Bankruptcy judges who have a notion that their job …

Coexisting Salps Exhibit Distinct Feeding Selectivity On Microorganisms In The North Pacific Subtropical Gyre, Anne W. Thompson, Kylee Lamberson, Kelly R. Sutherland

Biology Faculty Publications and Presentations

Mortality mechanisms play an important role in how oceanic microorganisms contribute to global biogeochemical cycles. Salps are widespread pelagic tunicates known to remove phytoplankton from coastal and high-latitude waters, but their interaction with microorganisms in the vast tropical and subtropical gyres is not well quantified. Using quantitative measurements of six major marine microorganisms in the guts of six distinct but co-occurring salp species from the North Pacific Subtropical Gyre, we examined the impact and dynamics of salp feeding on marine microorganisms in a vast open ocean region. All salps preferentially removed prey greater than 1 μm in diameter, including marine …

Staff Education To Increase Knowledge And Awareness Of Cultural Sensitivity Among Providers, Stephanie Chiamaka Anyanwu

Walden Dissertations and Doctoral Studies

This Doctor of Nursing Practice (DNP) project aimed to enhance cultural sensitivity among healthcare providers through an educational intervention in a local organization. With the U.S. foreign-born population exceeding 47 million, the need for culturally competent care has become paramount. The study involved nine participants who underwent a pretest and posttest assessment to evaluate their knowledge and awareness of cultural sensitivity. Results indicated a significant increase in knowledge, with pretest and posttest scores improving from a mean of 4.33 to 8.56 (p < 0.01). Awareness in key areas such as patient-provider relationships, cultural beliefs, and language barriers also showed marked improvement. These findings further support the necessity of ongoing cultural sensitivity training to enhance patient care and outcomes, highlighting the potential for broader application across healthcare institutions.

Faculty, Staff and Student Publications

Purpose: Antibody-drug conjugates (ADCs) have transformed the treatment of breast cancer. FDA-approved ADCs such as trastuzumab deruxtecan (T-DXd), sacituzumab govitecan (SG), and datopotamab deruxtecan (Dato-DXd) have demonstrated clinical benefit; however, drug resistance will almost inevitably emerge in the metastatic setting, and there is no established strategy for selecting subsequent ADCs after disease progression to the first exposure to the ADC. This study aimed to define mechanisms of acquired resistance and evaluate rational sequencing approaches.

Experimental design: We generated breast cancer cell lines resistant to T-DXd (TDXd-R) and SG (SG-R). We assessed antigen expression, internalization, and resistance pathways, including efflux transporter …

Liturgies Of The Self: Contemporary American Cult Fiction, Identity, And Narrative Evangelism, Kerry Hillis Goff

Electronic Theses and Dissertations Archive

“Liturgies of the Self: Contemporary American Cult Fiction, Identity, and Narrative Evangelism,” examines how American novels from 1980 to the present stage cultic logic as a cultural grammar of belonging. Across two cohorts—1980–2000 and 2001–present—the project demonstrates how narratives of consumerism, violence, embodiment, race, and simulation reveal identity as liturgical performance rather than autonomous selfhood. The first cohort—Don DeLillo’s White Noise (1985), Chuck Palahniuk’s Fight Club (1996), Bret Easton Ellis’s American Psycho (1991), Douglas Coupland’s Generation X (1991), and Katherine Dunn’s Geek Love (1989)—dramatizes cultic rituals through spectacle, grotesque display, and overt performance. DeLillo stages consumer spectacle as collective liturgy; …

Establishing Functional Communication Responses And Mands: A Scoping Review Of Teaching Procedures And Implications For Future Investigation., Kyle W. Dawson, Amanda N. Zangrillo, Samantha J. Bryan, Rebecca J. Barall, Colin G. Wehr

Manuscripts, Articles, Book Chapters and Other Papers

The functional communication response (FCR) shares fundamental properties with the mand, with both responses linking the relevant motivating operation and the reinforcer maintaining a response. The FCR differs from the mand in that the communication response has the expressed intention of replacing challenging behavior by providing an outlet to access the same functional reinforcer. Research describes the development of mand and FCR repertoires; however, no research to date elucidates differences and similarities in how these repertoires are established. A scoping review was selected to systematically map and compare instructional procedures across FCT and mand training studies. In this scoping review, …

Predictions Of Masses For Light Hybrid Baryons, Qi-Nan Wang, Ding-Kun Lian, Wei Chen, Hui-Min Yang, Hua-Xing Chen, Jason N.E. Ho, T. G. Steele

Faculty Work Comprehensive List

Within the method of parity-projected QCD sum rules, we study the mass spectra of light hybrid baryons with 𝐼⁡(𝐽𝑃) =1/2⁢(1/2±),3/2⁢(1/2±),1/2⁢(3/2±),3/2⁢(3/2±) by constructing the local 𝑞⁢𝑞⁢𝑞⁢𝑔 interpolating currents. We calculate the correlation functions up to dimension eight condensates at the leading order of 𝛼𝑠. The stable QCD Lapalce sum rules can be established for the positive-parity 𝑁1/2+,Δ3/2+,Δ1/2+ and negative-parity 𝑁1/2−,𝑁3/2−,Δ1/2− channels to extract their mass spectra. The lowest-lying hybrid baryons are predicted to be the positive-parity 𝑁1/2+ state around 2.01 GeV. These hybrid baryons mainly decay into conventional baryon plus meson final states. We propose to search for the light hybrid …
