Human Behavior In Domestic Environments: Prediction And Applications, Sharare Zehtabian

Electronic Theses and Dissertations, 2020-2023

A longstanding goal of human behavior science is to model and predict how humans interact with each other or with other systems. Such models are beneficial and have many applications, including designing and implementing assistive technologies, improving users' experiences and quality of life and making better decisions to create public policies. Behavior is highly complex due to uncertainties and a lack of scientific tools to measure it. Hence prediction of human behavior cannot be 100% accurate. However, prediction is also not hopeless because the biological needs, as well as cultural conventions (for instance, regarding meal times) set the general patterns …

Framework Of Big Data Analytics In Real Time For Healthcare Enterprise Performance Measurements, Ahmed Mohamed

Electronic Theses and Dissertations, 2020-2023

Healthcare organizations (HCOs) currently have many information records about their patients. Yet, they cannot make proper, faster, and more thoughtful conclusions in many cases with their information. Much of the information is structured data such as medical records, historical data, and non-clinical information. This data is stored in a central repository called the Data Warehouse (DW). DW provides querying and reporting to different groups within the healthcare organization to support their future strategic initiatives. The generated reports create metrics to measure the organization's performance for post-action plans, not for real-time decisions. Additionally, healthcare organizations seek to benefit from the semi-structured …

Using Peptide Design To Engineer Polyelectrolyte Complex Biomaterials, Sara Tabandeh

Electronic Theses and Dissertations, 2020-2023

The self-assembly of oppositely charged polymers provides a versatile platform to design materials for diverse applications in biology and medicine. Electrostatically-driven phase separation of oppositely charged polymers in aqueous solution gives rise to the formation of a polymer-rich phase called a polyelectrolyte complex (PEC). PECs can be in the form of liquid droplets (complex coacervates) or amorphous solid precipitates. Unlike synthetic polymers, peptides are good candidates for developing tailor-made formulations and structure-property relationships due to their biocompatibility, precise control over sequences, and ability to program hydrogen bonding interactions. However, little is known about the effect of combining additional molecular interactions …

Nevr: Learning Continuous Neural Video Representation With Local Feature Codes For Video Interpolation, Wentao Shangguan

McKelvey School of Engineering Graduate Student Theses & Dissertations

Video frame interpolation aims to synthesis a non-exists intermediate frame guided by two successive frames. Recently, some work shows excellent results in learning continuous representation of temporally-varying 3D objects with neural field (NF), which could be used for interpolating the original video. However, these methods require several videos from different viewing angles, the information of camera poses, learning for each specific scene, and achieving sub-optimal results for video frame interpolation. To this end, we propose a new learning neural field representation-based model, Neural Video Representation (NeVR) to learn a continuous representation of videos for high-quality video interpolation. Unlike the traditional …

Raw Versus Linear Acceleration In The Recognition Of Wrist Motions Related To Eating During Everyday Life, Shaurya Gupta

All Theses

This thesis investigates the difference between raw and linear acceleration in wrist motion for detecting eating episodes. In previous work, our group developed a classifier that analyzed linear motion and achieved good accuracy. However, the classifier can be volatile in the sense that when retrained and tested on the same data, accuracy varies, especially when trained on small amounts of data such as for a single individual. We hypothesize that in part this may be due to the noise in linear acceleration which is significantly larger relative to normal human wrist motions as compared to the noise in raw acceleration. …

Exploring The Relationship Between Broadband And Socioeconomic Health: A Case Study In Appalachia, Kyra Marie Palange

This thesis uses county-level Federal Communications Commission (FCC) Form 477 and Appalachian Regional Commission data to examine factors that affect socioeconomic health, with a particular focus on the impact of household broadband adoption, in rural areas of the Appalachian United States. Outcome variables of interest are percentage of people in poverty, per capita market income (i.e., the income one earns from participating in the economy through wages, investments, business income and the like), and number of excess deaths per 100,000 residents. The first chapter uses two multivariate multiple regression models, one using 2008 data and one using 2016 data, to …

In The Pines: Dung Beetle Community Composition In Longleaf Pine Habitat, Kelsea Lynn Young

All Theses

Dung beetle assemblages are recognized as ecological bioindicators, allowing us to monitor ecological impacts by observing community shifts. Acting as primary nutrient cyclers, they establish niche segregation by sometimes selecting dung based on species (e.g. coyote vs. deer) and by using dung in different ways (e.g. rollers vs. tunnelers). Longleaf pine savannahs are recognized as global hotspots for diversity. Species of dung beetles found within these ecosystems may differ substantially from those found in surrounding agricultural, residential or other forest land. Our objective was to investigate whether the exclusion of mammalian meso-predator exclusion impacts dung beetle abundance, species composition and …

Parametric Study Of Orthogonal Pantographic Lattice With Non-Linear Torsional Resistance At Pivots, Mahendra Singh Bisht

All Theses

Pantographic lattices are cellular solids comprised of continuous beam fibers intersecting at periodically spaced pivots. The pivots are simulated in the discrete finite element beam model as torsional springs with varied torsional stiffness across orders of magnitude. An important functional performance feature of pantographic lattices is their ability to undergo large deformation without inducing large stresses at the pivots. There is a need for predictive models of this nonlinear behavior. In this study, parameter studies on the order of magnitude and nonlinear material behavior of the torsional stiffness at the pivots, combined with and without nonlinear geometric beam kinematic behavior …

Core-Atac: A Deep Learning Model For The Functional Classification Of Regulatory Elements From Single Cell And Bulk Atac-Seq Data., Asa Thibodeau, Shubham Khetan, Alper Eroglu, Ryan Tewhey, Michael L. Stitzel, Duygu Ucar

Faculty Research 2021

Cis-Regulatory elements (cis-REs) include promoters, enhancers, and insulators that regulate gene expression programs via binding of transcription factors. ATAC-seq technology effectively identifies active cis-REs in a given cell type (including from single cells) by mapping accessible chromatin at base-pair resolution. However, these maps are not immediately useful for inferring specific functions of cis-REs. For this purpose, we developed a deep learning framework (CoRE-ATAC) with novel data encoders that integrate DNA sequence (reference or personal genotypes) with ATAC-seq cut sites and read pileups. CoRE-ATAC was trained on 4 cell types (n = 6 samples/replicates) and accurately predicted known cis-RE functions from …

Inactive Rhomboid Proteins Rhbdf1 And Rhbdf2 (Irhoms): A Decade Of Research In Murine Models., Lisa M. Burzenski, Benjamin E. Low, Vivek Kohar, Leonard D. Shultz, Michael V. Wiles, Vishnu Hosur

Faculty Research 2021

Rhomboid proteases, first discovered in Drosophila, are intramembrane serine proteases. Members of the rhomboid protein family that are catalytically deficient are known as inactive rhomboids (iRhoms). iRhoms have been implicated in wound healing, cancer, and neurological disorders such as Alzheimer's and Parkinson's diseases, inflammation, and skin diseases. The past decade of mouse research has shed new light on two key protein domains of iRhoms-the cytosolic N-terminal domain and the transmembrane dormant peptidase domain-suggesting new ways to target multiple intracellular signaling pathways. This review focuses on recent advances in uncovering the unique functions of iRhom protein domains in normal growth and …

Six-Fold Increase Of Atmospheric Pco2 During The Permian–Triassic Mass Extinction, Yuyang Wu, Daoliang Chu, Jinnan Tong, Haijun Song, Jacopo Dal Corso, Paul B. Wignall, Huyue Song, Yong Du, Ying Cui

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Permian–Triassic mass extinction was marked by a massive release of carbon into the ocean-atmosphere system, evidenced by a sharp negative carbon isotope excursion. Large carbon emissions would have increased atmospheric pCO2 and caused global warming. However, the magnitude of pCO2 changes during the PTME has not yet been estimated. Here, we present a continuous pCO2 record across the PTME reconstructed from high-resolution δ¹³C of C3 plants from southwestern China. We show that pCO2 increased from 426 +133/−96 ppmv in the latest Permian to 2507 +4764/−1193 ppmv at the PTME within about 75 kyr, and that the reconstructed …

Structural Dynamics And Encapsulation Properties Of Polyelectrolyte Complex Micelles, Sachit Shah

Electronic Theses and Dissertations, 2020-2023

Charged therapeutics such as nucleic acids and proteins can treat a vast range of human diseases that are traditionally undruggable. Their broadness in treating disease is due to their ability to influence cellular function. However, their high charge density and physiological barriers such as enzymatic degradation, hinder the deliverability of these molecules to the sites of disease. Polyelectrolyte complex (PEC) micelles are core-corona nanostructures that can encapsulate charged molecules and offer a platform for delivery. PECs form the core, when two oppositely charged polyelectrolytes are mixed in an aqueous solution, and the micelle corona is a neutral hydrophilic polymer that …
