Interplay Between Computational Techniques And Quantum Theory: Advancing Quantum Chaos And Quantum Error Correction, Refaat Ismail

Theses and Dissertations--Physics and Astronomy

This dissertation investigates computational techniques addressing critical problems arising within quantum chaos and quantum error correction (QEC). First, we investigate quantum dynamics via the Lanczos algorithm, establishing how its computational features — branching patterns, convergence, and complexity saturation — relate to physical properties like spectral statistics and operator matrix elements. We derive a formula connecting Lanczos coefficients to spectral densities for two-branched Lanczos sequences, revealing how branching patterns encode level repulsion—a hallmark of quantum chaos. Furthermore, we develop an analytic framework predicting Krylov complexity saturation from static system properties alone. Specifically, we decompose the saturation value into a spectral density-dependent …

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 …

How To Eat Right And Why We Ask That Question, Heather N. Carpenter

Theses and Dissertations--Gender and Women's Studies

What does it mean to “eat right?” The notion is, of course, culturally, historically, nationally, politically, ethnically, and class determined. For the purposes of this project, however, I am particularly interested in changing notions of what it means to “eat right” within the post-World War II to the early new millennium American context, as such notions are represented within the prescriptions of popular culture. I turn to popular culture because this is the commons of the hegemonic call to “normalcy”—this is where we all learn to imitate, aspire, or rebel against a generic American consumer-self in conformity with the biases, …

Examining Cognition In Action, Anthony P. Zanesco, Ekaterina Denkova, Jordan Barry, Costanza Alessio, Amishi P. Jha

Psychology Faculty Publications

Introduction: There is growing interest in understanding how individual differences in cognitive abilities contribute to military performance. Laboratory-based cognitive tasks, which are well-suited for assessing specific cognitive capacities, offer a controlled and efficient approach for evaluating these differences. If performance on such tasks corresponds with operationally relevant performance, these measures could serve as valuable tools for evaluation, selection, and targeted training interventions to enhance military readiness. Here, we examined associations between performance on laboratory tasks of attentional control and operationally relevant tasks in an augmented reality military training environment. Methods: Across two study rounds, 45 squads of active-duty U.S. Army …

Innovative Biomechanical And Engineering-Based Assessments Of Hip Mechanics In Individuals With Hip-Related Pain, Holly M. Stanze

Theses and Dissertations--Kinesiology and Health Promotion

Individuals with hip-related pain exhibit altered movement patterns, and worse fear of movement (kinesiophobia), compared to asymptomatic controls. Exacerbation of hip pain during movement and the role of hip symptom duration may help further our understanding of specific movement patterns that are associated with hip-related pain. A better understanding of the potential connections between hip-related symptom duration, kinesiophobia, hip pain during movement, and lower limb mechanics in those with hip-related pain may allow for more efficient referrals to clinicians and lead to more effective rehabilitation. In addition, the impact of hip-related pain on intra-articular hip loading patterns is not well …

Bridging Awareness And Access: Outdoor Recreation And Physical Activity In Eastern Kentucky, Timothy Mckay

Theses and Dissertations--Kinesiology and Health Promotion

Physical inactivity remains a pressing challenge in Appalachian Kentucky, where high obesity rates intersect with limited access to structured exercise facilities. This dissertation investigated the extent to which participation in outdoor recreation supports adherence to physical activity (PA) recommendations and explored community awareness of local public lands. Surveys from 52 adult participants in Knox County revealed strong engagement in outdoor activity, with participation significantly predicting compliance with national PA guidelines. Educational attainment was also associated with higher rates of PA compliance, pointing to the influence of literacy and awareness in health behaviors. Reliability testing of the Outdoor Physical Activity Attitude …

Reevaluating The Opportunity For Wind Energy In Kentucky: Advancing Technology, Changing Economics, And Generation Complementarity, Lawrence E. Holloway, Aron Patrick, Dan M. Ionel

Electrical and Computer Engineering Faculty Publications

Recent developments in wind turbine technology, new wind resource data, and new federal tax credits for renewable energy are increasing the suitability of wind electricity generation in Kentucky. In 2022, Kentucky had 68% of its electricity from coal and in 2023 was one of eight U.S. states with no utility-scale wind generation. In the past, the state has been viewed as being generally unsuitable for wind power generation. While wind is not the most economic resource in Kentucky, all states bordering the Commonwealth have wind power. Wind power generation in Kentucky appears increasingly likely in the coming decades to play …

Physicochemical Property Effects On Immune Modulating Polymeric Nanoparticles: Potential Applications In Spinal Cord Injury, Daniel J. Kolpek, Jaechang Kim, Hisham Mohammed, John C. Gensel, Jonghyuck Park

Markey Cancer Center Faculty Publications

Nanoparticles (NPs) offer promising potential as therapeutic agents for inflammation-related diseases, owing to their capabilities in drug delivery and immune modulation. In preclinical studies focusing on spinal cord injury (SCI), polymeric NPs have demonstrated the ability to reprogram innate immune cells. This reprogramming results in redirecting immune cells away from the injury site, downregulating pro-inflammatory signaling, and promoting a regenerative environment post-injury. However, to fully understand the mechanisms driving these effects and maximize therapeutic efficacy, it is crucial to assess NP interactions with innate immune cells. This review examines how the physicochemical properties of polymeric NPs influence their modulation of …

A New Power Airflow Harvester Improves Grass Seed Yield And Quality In Central Queensland, Australia, J H. Wildin, Dingfa Zhou, A Dobson

IGC Proceedings (1977-2023)

Most perennial tropical grasses produce new seedheads over a period extending up to 4 weeks, Seeds mature and ripen up to 4 weeks after inflorescence emergence. The dilemma for seed producers using one­pass harvesting has been to time the harvesting operation to maxmise. recovery of mature seed, Harvested immature seeds and inert material adversely affect seed purity and germination tests. Light fluffy seeds such as buffel and bluegrasses are generally difficult to harvest with grain crop harvesters, and paddle beater harvesters have been used for simplicity and economy. Over the last 3 years, tractor-mounted brush harvesters using 4 rows of …

Topography And Wildfire Jointly Mediate Postfire Ecosystem Multifunctionality In A Chinese Boreal Forest, Jianjian Kong, Zifan Ding, Wenhua Cai, Jiaxing Zu, Bo Liu, Jian Yang

Earth and Environmental Sciences Faculty Publications

Both topography and wildfire can exert significant influences on ecosystem processes and functions during boreal forest successions. However, their impacts on ecosystem multifunctionality (EMF) remain unclear. A mega-fire burned an area of 8700 hectares in the Great Xing’an Mountains in 2000, creating a wide range of fire severity levels across various topographic positions. This provided a unique opportunity to explore the impacts of mixed-severity fire disturbance in boreal forests. We evaluated the effect pathways of wildfire and topography on aboveground multifunctionality (AEMF), soil multifunctionality (SEMF), and overall multifunctionality (OEMF). We found that high-severity burning resulted in lower AEMF, SEMF, and …
