Estimating the Cost of Locomotion in Common Bottlenose Dolphins: Calibration, Validation, and Application to Study the Impacts of Disturbance
(2021)Estimates of the energetic costs of locomotion (COL) are necessary to understand one of the potential impacts of anthropogenic disturbance on marine mammals. A new generation of biologging devices has enabled the measurement ... -
Understanding Photoexcited Charge Carrier Dynamics in Methylammonium Lead Iodide Perovskite Thin Films by Pump Probe Microscopy
(2021)Metal halide perovskite-based thin films, the light harvesting layer in perovskite solar cells, have received increasing attention since 2012. Although many studies have focused on elucidating the complicated dynamics involved ... -
Data-Driven Parameter Estimation of Time Delay Dynamical Systems for Stability Prediction
(2021)Subtractive machining operations such as milling, turning, and drilling are an essential part of many manufacturing processes. Unfortunately, under certain combinations of machine settings, the motion of the cutting tool ... -
Harmonic Acoustics for Single Cell Manipulation
(2021)Technologies that can manipulate single particles and cells in a high precision, high throughput and contact-free manner have long been motivated by applications in materials science, physics, medicine, and the life sciences. ... -
Geometry-Based Thermodynamic Homogenization for Porous Media, with Application to Resilience Prediction and Gyroscopic Sustainability
(2021)Understanding and predicting the behavior of porous media holds unexpected potential for technological advances toward resilience and sustainability. Indeed, these materials are ubiquitous and exhibit a rich palette of processes, ... -
Multivariate Dynamic Modeling and Bayesian Decision Analysis for Macroeconomic Policy
(2021)There is abundant interest in incorporating information from many economic time series to improve forecasts and inform policy. Traditional methods include time-varying vector autoregression models, in which the series are ... -
The Mourning of Rama IX
(2021)This dissertation is an anthropological study of the mourning of Thailand’s King Bhumibol Adulyadej. Bhumibol’s reign spanned from the end of World War II, through the Indochina conflict, and into the 21st century. The only ... -
Development of Low-cost Imaging Tools for Screening of Retinal Biomarkers in Alzheimer’s Disease
(2021)Alzheimer’s disease (AD) is a neurodegenerative disease currently affecting 5.8 million Americans and more than 50 million people worldwide. It is a progressive disease that destroys cognitive functions, leading to dementia. ... -
Low Energy Neutrino-Nucleus Interactions at the Spallation Neutron Source
(2021)There are few existing measurements of low energy neutrino-nucleus interactions. The COHERENT collaboration is seeking to measure several of these processes using the intense pulsed neutrinos produced at the Spallation Neutron ... -
The Latency Budget: How to Save and What to Buy
(2021)Novel applications have driven innovation in the Internet over decades. Electronic mail and file sharing drove research for communication and congestion control protocols. Hypertext documents then created the web and put ... -
Safety Considerations and Clinical Benefit Analysis for the Use of Elevated Acoustic Output in Diagnostic Ultrasound Imaging
(2021)Diagnostic ultrasound imaging is sometimes unable to yield clinically useful data. This is caused by the presence of body walls. This thesis examines how body walls impacts the propagation of ultrasound in the human body ... -
Sophocles’ Ancient Readers: The Role of Scholarship on the Reception of Greek Tragedy
(2021)There is a modern scholarly consensus that Sophocles’ popularity was so great in antiquity that criticism surrounding him was overwhelmingly positive but vague and without depth; he was, in their view, almost “beyond criticism” ... -
Investigating Bottlenose Dolphin (Tursiops truncatus) Cardiac Frequency and Cardiac Contractility Using a Novel Physio-logging Tag
(2021)Vertebrate animals undergo a constellation of physiological responses when they experience submersion. These responses, collectively known as the dive response, include apnea (breath-hold), bradycardia (a reduction in heart ... -
Search for new phenomena using three-photon final states in data collected with the ATLAS detector at the Large Hadron Collider
(2021)This thesis presents a search for new phenomena using three high-$p_T$ photons in the final state. In some Beyond the Standard Model (BSM) theories, a vector boson, $Z^\prime$, can decay to a pseudoscalar, $a$, and a photon, ... -
Of My Own for Woodwind Quintet and String Quartet; Constructing a Compositional Language through Musical Borrowing: Joan Tower’s Homage to Beethoven, Steps, and Made in America
(2021)This dissertation consists of two distinct parts. The first is an original music composition. The second is an analytical article about Joan Tower’s musical language through the lens of musical borrowing in three works.Chapter ... -
Intra-Operative Surgical Instrument Tracking with Radio-Frequency Identification
(2021)As data revolutionizes supply chains across diverse industries, healthcare lags. Sensor systems have struggled to automate the capture of actionable data without impeding clinical workflows. This work focuses on the development ... -
Methodologies and analysis of metabolic flux in mammalian systems
(2021)Quantification of metabolic fluxes has broad applications in studying metabolic physiology. Isotope tracing with heavy labeled carbon (13C labeled metabolic flux analysis, 13C-MFA) is a promising strategy due to its ability ... -
Metabolic Regulation of Mast Cell Regranulation
(2021)Mast cells (MCs) are long-lived hematopoietic cells located within tissues. These cells are densely packed with granules containing preformed bioactive components that are released within seconds to minutes upon activation ... -
Machine Learning Approaches to Improve Diagnosis and Management of Mammographic Calcifications
(2021)Currently the most common and effective procedure of early detection of breast cancer is through screening mammography. Mammography detects not only invasive cancers, but also in situ lesions including ductal carcinoma in ... -
