3D dynamic in vivo imaging of joint motion: application to measurement of anterior cruciate ligament function
(2019)More than 400,000 anterior cruciate ligament (ACL) injuries occur annually in the United States, 70% of which are non-contact. A severe consequence of ACL injury is the increased risk of early-onset of osteoarthritis (OA). ... -
3D Human Skeletal Muscle Model for Studying Satellite Cell Quiescence and Pompe disease
(2021)Tissue-engineered skeletal muscle presents promising opportunities for developing high-fidelity in vitro models for investigating human muscle biology in the areas of regeneration and disease. In muscle regeneration, satellite ... -
3D Microwave Imaging through Full Wave Methods for Heterogenous Media
(2011)In this thesis, a 3D microwave imaging method is developed for a microwave imaging system with an arbitrary background medium. In the previous study on the breast cancer detection of our research group, a full wave inverse ... -
3D Object Representations for Robot Perception
(2019)Reasoning about 3D objects is one of the most critical perception problems robots face; outside of navigation, most interactions between a robot and its environment are object-centric. Object-centric robot perception has ... -
3D Printable Lithium Ion Batteries and the Effect of Aspect Ratio of CuAg Nanowires on Graphite Anode Performance.
(2018)The majority of consumer electronic devices, electric vehicles, and aerospace electronics are powered by lithium ion batteries because of their high energy and power densities. Commercially available lithium ion batteries ... -
A "Trinitarian" Theology of Religions? An Augustinian Assessment of Several Recent Proposals
(2007-05-04)Contemporary theology is driven by a quest to make the doctrine of the Trinity “relevant” to a wide variety of concerns. Books and articles abound on the Trinity and personhood, the Trinity and ecclesiology, the Trinity ... -
A 3-D Multiparametric Ultrasound Elasticity Imaging System for Targeted Prostate Biopsy Guidance
(2023)Prostate cancer is the most common cancer and second-leading cause of cancer death among men in the United States. Early and accurate diagnosis of prostate cancer remains challenging; following an abnormal rectal exam or ... -
A 3D Active Microwave Imaging System for Breast Cancer Screening
(2008-12-11)A 3D microwave imaging system suitable for clinical trials has been developed. The anatomy, histology, and pathology of breast cancer were all carefully considered in the development of this system. The central component ... -
A 3D Geometric Morphometric Investigation of Relatedness in the Modern Human, Chimpanzee, and Homo naledi Postcranial Skeleton
(2023)Studies of skeletal variation form the basis of our understanding of our species’ history and diversity. This most commonly takes the form of comparative, between- species studies aimed at reconstructing phylogenetic ... -
A Bayesian Model of Cognitive Control
(2014)"Cognitive control" describes endogenous guidance of behavior in situations where routine stimulus-response associations are suboptimal for achieving a desired goal. The computational and neural mechanisms underlying this ... -
A Beautiful Noise: A History of Contemporary Worship Music in Modern America
(2015)How did rock and roll, the best music for worshipping the devil, become the finest music for worshipping God? This study narrates the import of rock music into church sanctuaries across America via the rise of contemporary ... -
A bidirectional switch to treat colonic dysmotility
(2023)Severe constipation can be life-threatening and disproportionately affects patients who may not benefit from conventional treatments. Sacral nerve stimulation (SNS) is an alternative to laxatives and pharmaceuticals, and ... -
A Biopsychosocial Study of the Mammography Pain Experiences of Breast Cancer Survivors
(2009)Based on a biopsychosocial model of mammography pain, the current study assessed if specific biological and psychosocial factors were associated with higher reported mammography pain in early stage breast cancer survivors. ... -
A Central Role for Hypoxia-inducible Transcription Factor Signaling in the Regulation of Skeletal Lineage Cells
(2022)Osteoporosis and low bone density affect an estimated 54 million adults of 50 years and over in the United States, resulting in $19 billion in costs for osteoporosis-related bone breaks. Current treatments include the use ... -
A CG-FFT Based Fast Full Wave Imaging Method and its Potential Industrial Applications
(2015)This dissertation focuses on a FFT based forward EM solver and its application in inverse problems. The main contributions of this work are two folded. On the one hand, it presents the first scaled lab experiment system ... -
A Class of Tetrahedral Finite Elements for Complex Geometry and Nonlinear Mechanics: A Variational Multiscale Approach
(2019)In this work, a stabilized finite element framework is developed to simulate small and large deformation solid mechanics problems involving complex geometries and complicated constitutive models. In particular, the focus ... -
A Clonal Analysis of Zebrafish Heart Morphogenesis and Regeneration
(2014)As vertebrate embryos grow and develop into adults, their organs must acquire mass and mature tissue architecture to maintain proper homeostasis. While juvenile growth encompasses a significant portion of life, relatively ... -
A Cloud-Based Infrastructure for Cancer Genomics
(2020)The advent of new genomic approaches, particularly next generation sequencing (NGS) has resulted in explosive growth of biological data. As the size of biological data keeps growing at exponential rates, new methods for ... -
A Combined Experimental and Modeling Approach Unraveling the Mechanics Behind Drying-induced Fractures in Soils
(2023)This dissertation aims to understand the physics of geomaterial under different loading rates, employing a combination of experimental analysis and theoretical modeling. After obtaining a comprehensive understanding ... -
A Compact Cryogenic Package Approach to Ion Trap Quantum Computing
(2022)Ion traps are a leading candidate for scaling quantum computers. The component technologies can be difficult to integrate and manufacture. Experimental systems are also subject to mechanical drift creating a large maintenance ...
