Synthesis Of Microcapsules And Inclusion Complexes Consisting Of Hydrophobic Cores And Polysaccharidic Shells For Thermal Energy Management And Packaging, Gulbahar Bahsi-Kaya

Theses and Dissertations

Active substances can be stabilized to be protected from undesirable reactions, aggregation, and leaking, which would keep the intended functions of the active substances without premature degradation. Among such active substances are paraffin-based organic phase change materials (PCMs) and essential oils (EOs), which feature attractive characteristics, e.g., high latent heat of fusion and inherent antimicrobial activity. However, their high volatility requires an effective stabilization strategy. Petroleum-based synthetic polymers have often been employed to stabilize PCMs and EOs by encapsulation and complexation pathways. Despite their proven effectiveness, these polymers are from non-renewable resources, and non-degradable and often toxic, which has prompted …

Distribution Of Woodpecker Activity Relative To Wooden Utility Structure Usage In The Southeastern United States, Hannah Chelsea Wright

Theses and Dissertations

Woodpeckers are a group of avian species that cause damage to wooden power utility structures. In the southeastern United States, Tennessee Valley Authority (TVA), has accrued an estimated $5 million USD annually from woodpecker damage. Previous work has focused on effectiveness of reactive mitigation and restoration efforts with little investigation of preventative methods. To address this knowledge gap, this study will i) use species distribution model techniques to predict damage suitability across the TVA service area, ii) use Bayesian hierarchical community model techniques to estimate species richness of the woodpecker community in the service area, and iii) recommend target areas …

Novel Considerations For Lightning Strike Damage Mitigation Of Carbon Fiber Reinforced Polymer Matrix (Cfrp) Composite Laminates, Kamran Yousefpour

Theses and Dissertations

Lightning current with high amplitude disseminates through the body of aircraft and causes physical damages including the delamination and puncture of materials. Also , such high-amplitude and high-frequency current could interfere with electronic devices through electromagnetic coupling with the conductive interfaces of an airplane. Hence, robust protection against lighting strike is essential in the aerospace industry. Carbon Fiber Reinforced Polymer (CFRP) Matrix Composites have become significant alternatives to conventional metal-base materials. Despite the superior physical and structural properties of CFRP composites, these materials are vulnerable to lightning strikes due to the low electrical conductivity compared to the metal counterpart. Many …

Faculty, Staff and Students Publications

The functional role of long noncoding RNAs (lncRNAs) in inherited metabolic disorders, including phenylketonuria (PKU), is unknown. We demonstrated that the mouse lncRNA Pair and human HULC associate with phenylalanine hydroxylase (PAH). Pair-knockout mice exhibited excessive blood phenylalanine, musty odor, hypopigmentation, growth retardation, and progressive neurological symptoms including seizures, which faithfully models human PKU. HULC depletion led to reduced PAH enzymatic activities in human induced pluripotent stem cell (hiPSC)-differentiated hepatocytes. Mechanistically, HULC modulated the enzymatic activities of PAH by facilitating PAH-substrate and PAH-cofactor interactions. To develop a therapeutic strategy for restoring liver lncRNAs, we designed GalNAc-tagged lncRNA mimics that …

Reduction Of Order, Resummation, And Radiation Reaction, Robin Ekman, Tom Heinzl, Anton Ilderton

School of Engineering, Computing and Mathematics

The Landau-Lifshitz equation is the first in an infinite series of approximations to the Lorentz-Abraham-Dirac equation obtained from “reduction of order.” We show that this series is divergent, predicting wildly different dynamics at successive perturbative orders. Iterating reduction of order ad infinitum in a constant crossed field, we obtain an equation of motion which is free of the erratic behavior of perturbation theory. We show that Borel-Padé resummation of the divergent series accurately reproduces the dynamics of this equation, using as little as two perturbative coefficients. Comparing with the Lorentz-Abraham-Dirac equation, our results show that for large times the optimal …

Classical Resummation And Breakdown Of Strong-Field Qed, T. Heinzl, A. Ilderton, B. King

School of Engineering, Computing and Mathematics

QED perturbation theory has been conjectured to break down in sufficiently strong backgrounds, obstructing the analysis of strong-field physics. We show that the breakdown occurs even in classical electrodynamics, at lower field strengths than previously considered, and that it may be cured by resummation. As a consequence, an analogous resummation is required in QED. A detailed investigation shows, for a range of observables, that unitarity removes diagrams previously believed to be responsible for the breakdown of QED perturbation theory.

Microbes On The Mountain: Plant-Microbe Associations And Interactions On Mount St. Helens, Emily Rose Wolfe

Dissertations and Theses

Plant-microbe associations and interactions provide critical context to studies in both community and ecosystem ecology, especially in systems that are relatively new and still undergoing early successional processes. Microbes can colonize the surfaces and interiors of all plant tissues, and these assemblages vary in composition both spatially and temporally, even within the same plant. Endophytes are bacteria or fungi that spend most of their lifecycles living within plant tissues asymptomatically--typically, "endophyte" refers specifically to aboveground tissues such as leaves and stems, and therefore may have direct influences on defenses against herbivory, pathogen or pest tolerance, and even afterlife effects on …

Sin In Business And Business In Sin: Negative Externalities, Total Depravity, And Freedom From Perfection, Kathryn D. Blanchard

Journal of Religion and Business Ethics

It is not difficult to find examples of sin in business. These include blatant individual sins like theft or fraud, as well as larger systemic failures such as negative social and ecological externalities. It is a task of Christian business ethics to address such failures, but we invariably come up against problems that defy easy solutions, no matter how scrupulously we try to root them out. This is because business itself—like all human life—exists under conditions of sin. The Calvinist notion of total depravity reframes “sin in business” as “business in sin,” necessitating greater humility about the possibility of good …

High-Throughput Discovery Of Novel Cubic Crystal Materials Using Deep Generative Neural Networks, Yong Zhao, Mohammed Al-Fahdi, Ming Hu, Edirisuriya M.D. Siriwardane, Yuqi Song, Alireza Nasiri, Jianjun Hu

Faculty Publications

High-throughput screening has become one of the major strategies for the discovery of novel functional materials. However, its effectiveness is severely limited by the lack of sufficient and diverse materials in current materials repositories such as the open quantum materials database (OQMD). Recent progress in deep learning have enabled generative strategies that learn implicit chemical rules for creating hypothetical materials with new compositions and structures. However, current materials generative models have difficulty in generating structurally diverse, chemically valid, and stable materials. Here we propose CubicGAN, a generative adversarial network (GAN) based deep neural network model for large scale generative design …

Protein-Based Nanofibers And Thin Films For Drug Delivery Applications, Christopher R. Gough

Theses and Dissertations

Corn zein and silk are both widely available, easy to extract proteins making them valuable replacements for synthetics. Zein and silk are also promising biomaterials in several applications. This work explores the use of both proteins as drug delivery vehicles by loading 1-Dimensional micro-nanofibers and 2-Dimensional thin films with model drugs or the topical therapeutic sodium citrate. Using a formic acid solvent, powdered zein protein or silk fibers were dissolved into solution and then casted into 2D films or spun into 1D fibers through air-spraying. During dissolution, therapeutic products are added. SEM images showed that fibers maintain their small diameter …

Unbiased Automated Quantitation Of Ros Signals In Live Retinal Neurons Of Drosophila Using Fiji/Imagej, Prajakta Deshpande, Neha Gogia, Anuradha Venkatakrishnan Chimata, Amit Singh

Biology Faculty Publications

Numerous imaging modules are utilized to study changes that occur during cellular processes. Besides qualitative (immunohistochemical) or semiquantitative (Western blot) approaches, direct quantitation method(s) for detecting and analyzing signal intensities for disease(s) biomarkers are lacking. Thus, there is a need to develop method(s) to quantitate specific signals and eliminate noise during live tissue imaging. An increase in reactive oxygen species (ROS) such as superoxide (O2•-) radicals results in oxidative damage of biomolecules, which leads to oxidative stress. This can be detected by dihydroethidium staining in live tissue(s), which does not rely on fixation and helps prevent stress on tissues. However, …

A Constrained Optimal Hear-Through Filter Design Approach For Earphones, Yongjie Zhuang, Yangfan Liu

Publications of the Ray W. Herrick Laboratories

Signal characteristics can be altered when sound from environment transmits through earphones to the ear canal. A hear-through filter is usually implemented in an earphone to create a more natural hearing experience. Hear-through filter is also important in augmented reality audio applications. In this paper, a constrained optimal hear-through filter design approach is proposed, where the hear-through filter is designed using a formulation similar to that for a constrained active noise control filter design. One advantage of such a filter design approach is that, compared with the commonly used direct plant response inversion method, the leakage sound around and through …

An interactive spatial web portal, ODT Flow Explorer, is developed to allow users …

An End-To-End Cnn With Attentional Mechanism Applied To Raw Eeg In A Bci Classification Task, Elnaz Lashgari, Jordan Ott, Akima Connelly, Pierre Baldi, Uri Maoz

Psychology Faculty Articles and Research

Objective. Motor-imagery (MI) classification base on electroencephalography (EEG) has been long studied in neuroscience and more recently widely used in healthcare applications such as mobile assistive robots and neurorehabilitation. In particular, EEG-based motor-imagery classification methods that rely on convolutional neural networks (CNNs) have achieved relatively high classification accuracy. However, naively training CNNs to classify raw EEG data from all channels, especially for high-density EEG, is computationally demanding and requires huge training sets. It often also introduces many irrelevant input features, making it difficult for the CNN to extract the informative ones. This problem is compounded by a dearth of training …

Urban Farming Design In Los Angeles: An Adaptive Reuse Project In Response To Food Crisis And Housing Crisis, Pin-Han Su

Theses

As the world population is constantly growing and will reach 9 billion people by 2050, the current danger to the world's food supply system creates a severe challenge. By 2050, more populations will be living in the cities and creating higher demand on food supply, but the farmable lands on our planet could be much less because of climate change and urbanization. Agricultural leaders have argued that cities will need to produce food internally to respond to demand by increasing population and to avoid harmful pollution and unaffordable food prices. Architecture, as the most influential element affecting our daily life, …
