Precision Measurement Of The Muon’ S Anomalous Precession Frequency Using Energy Integrated Analysis In The Fermilab Muon G- 2 Experiment, Joseph Peck

Theses and Dissertations--Physics and Astronomy

This dissertation investigates the anomalous magnetic moment of the muon, aµ, through the Fermilab Muon g -2 Experiment, which aims to measure aµ to a precision of about 140 parts-per-billion.

Muons were injected into a magnetic storage ring where their decay positrons were detected by calorimeters. The changing spin and momentum orientation leads to an oscillation in decay positron counts, known as the anomalous precession frequency ! a. Using the magnetic field and !a measurements, we can determine the value of a µ. This study focuses on the Q-Method determination of !a, which utilizes an energyintegrated reconstruction rather than high-energy …

Pedagogical Idealism, Race, And The Specter Of Africa In Josefina Aldecoa’S Historia De Una Maestra And Donato Ndongo’S Las Tinieblas De Tu Memoria Negra, Parker Lawson

Funded Scholarship

This article examines two contemporary Spanish novels, Josefina Aldecoa’s Historia de una maestra (1990) and Donato Ndongo’s Las tinieblas de tu memoria negra (1987), to assess the status of pedagogical idealism and experimentation with particular attention to Equatorial Guinea. Where previous scholarly attention to Aldecoa’s novel focuses on the protagonist’s credentials as a progressive pedagogue, this article draws attention to Gabriela’s etapa guineana to argue that the text cripples under the weight of postcolonial analysis as regards race, religion, class, and language. Drawing the novel into comparison with Ndongo’s text, the article argues that Spanish colonial pedagogy flattened, or sought …

Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease, Everest Castaneda, Elissa Chesler, Erich J. Baker

Funded Scholarship

Substance use disorders (SUDs) are heterogeneous diseases with 

overlapping biological mechanisms and often present with co-occurring disease, 

such as cardiovascular disease (CVD). Gene networks associated with SUDs 

also implicate additional biological pathways and may be used to stratify 

disease subtypes. Node and edge arrangements within gene networks impact 

comparisons between classes of disease, and connectivity metrics, such as 

those focused on degrees, betweenness, and centrality, do not yield sufficient 

discernment of disease network classification. Comparatively, the graph 

spectrum’s use of comprehensive information facilitates hypothesis testing 

and inter-disease clustering by using a larger range of graph characteristics. 

By adding a connectivity-based …

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

One of the primary purposes of education is to help students make sense of their lived experiences. In the process of becoming, students navigate multiple relationships (school, peers, adults, and with self). These relationships often cause conditions of uncertainty which can be managed and transformed using restorative practices in tandem with the academic disciplines taught in school. Over the last decade this has been my inquiry puzzle, “As educators, how can we embrace uncertainty with students as a way of helping to empower them through their dignity, with the academic disciplines as a lens through which relational learning occurs in …

Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This research study investigates statistical approaches for modeling the movement patterns of white-tailed deer in Louisiana using GPS tracking data. We start by classifying the latent behavioral states using a hidden Markov model (HMM) and then integrate those inferred states into a state-dependent step selection framework to evaluate the land cover preferences. Standard HMMs, however, assume the same movement patterns for all animals, overlooking the differences due to characteristics such as sex, age, breeding season, etc.

To address this limitation, we extend the modeling framework to incorporate the group-level structure defined by similar characteristics or conditions to assess whether such …
