Supplementary Files For "Creating A Universal Depth-To-Load Conversion Technique For The Conterminous United States Using Random Forests", Jesse Wheeler, Brennan Bean, Marc Maguire

Browse all Datasets

As part of an ongoing effort to update the ground snow load maps in the United States, this paper presents an investigation into snow densities for the purpose of predicting ground snow loads for structural engineering design with ASCE 7. Despite their importance, direct measurements of snow load are sparse when compared to measurements of snow depth. As a result, it is often necessary to estimate snow load using snow depth and other readily accessible climate variables. Existing depth-to-load conversion methods, each of varying complexity, are well suited for snow load estimation for a particular region or station network, but …

Mitigate Negative Effects In Spillover Crises, Jun Zhang

Dissertations - ALL

When two brands are perceived as closely associated with each other due to industry membership, negative perceptions of and emotions towards the brand in crisis may transfer to another brand, known as negative spillover effects. Negative spillover effects of one brand's crisis can often lead to undeserved losses in financial returns and reputation for the entire industry or rival brands within the same industry. Spillover crises have been empirically documented among various inter-organizational relationships. However, despite the importance of understanding when a spillover crisis occurs and how to manage it, research in crisis communications has paid relatively little attention to …

Binary Neutron Star Mergers: Gravitational-Wave Measurements Of Their Parameters And The Nuclear Equation Of State, Daniel Roger Finstad

Dissertations - ALL

Since making the first direct detection of gravitational waves in 2015, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) together with the Virgo observatory has detected an additional 51 confirmed signals from binary mergers. Two of these signals, GW170817 and GW190425, were identified as binary neutron star mergers. As detector sensitivity improves we expect to see many more binary neutron star merger events, both from future observing runs of the LIGO-Virgo network and from planned third-generation detectors. These new detections will provide an exquisite look at the nature of these systems and of neutron stars themselves. This thesis describes how gravitational-wave …

Some New Results In Distributed Tracking And Optimization, Pranay Sharma

Dissertations - ALL

The current age of Big Data is built on the foundation of distributed systems, and efficient distributed algorithms to run on these systems.With the rapid increase in the volume of the data being fed into these systems, storing and processing all this data at a central location becomes infeasible. Such a central \textit{server} requires a gigantic amount of computational and storage resources. Even when it is possible to have central servers, it is not always desirable, due to privacy concerns. Also, sending huge amounts of data to such servers incur often infeasible bandwidth requirements.

Vitamin D Modulates Rett Syndrome Phenotypes And Underlying Cellular Pathways In An Mecp2-Mutant Mouse Model, Mayara De Cassia Ribeiro

Dissertations - ALL

Rett syndrome (RTT) is a progressive and severe X-linked neurodevelopmental disorder caused by mutations in the transcriptional regulator MECP2. There is currently no effective treatment for RTT. Female RTT patients develop relatively normally during the first 6-18 months of life, after which they undergo a period of rapid regression, losing the ability to talk, walk and purposefully use their hands, in addition to suffering from deceleration of head growth, and onset of repetitive, autistic behaviors. RTT symptoms can be partially reversed by the re-expression of Mecp2 in adult mice, suggesting the potential for post-symptomatic therapeutic intervention. Among the many dysfunctions …

Multimode Circuit Quantum Electrodynamics With Superconducting Metamaterial Resonators, . Indrajeet

Dissertations - ALL

Superconducting devices in circuit quantum electrodynamics (cQED) systems are one of the leading approaches for realizing scalable quantum information processors. The combination of cQED architectures with multimode resonator systems can provide a flexible platform for performing analog quantum simulations, storing quantum information, and generating complex entangled states. Metamaterial resonant structures made from arrays of superconducting lumped circuit elements can exhibit microwave mode spectra with left-handed dispersion, resulting in a high density of modes in the same frequency range where superconducting qubits are typically operated, as well as a bandgap at lower frequencies that extends down to dc. In this thesis, …

Molecular Interfaces And Heterogeneous Bubble Nucleation From Heated Surfaces At Nanoscale, Manish Gupta

Dissertations - ALL

Heat transfer from a solid surface to fluid occurs in numerous applications, such as boilers, refrigerators, power electronics, etc., and include various underlying phenomena of thin-film evaporation, boiling, condensation, surface wetting, and droplet evaporation. Several studies show that heat transfer can be enhanced significantly by incorporating micro and nanoscale features onto surfaces. Phase change heat transfer plays an important role in dissipating energy from hot surfaces and distributing it to bulk liquid due to high latent heat of liquids. Boiling, a phase change heat transfer phenomenon, happens when the surface is heated to a temperature above the saturation temperature of …

Faculty Research 2021

The dysregulation of microRNA (miRNA) is implicated in cancer, inflammation, cardiovascular disorders, drug resistance, and aging. While most researchers study miRNA's role as a biomarker, for example, to distinguish between various sub-forms or stages of a given disease of interest, research is also ongoing to utilize these small nucleic acids as therapeutics. An example of a common pleiotropic disease that could benefit from miRNA-based therapeutics is inflammatory bowel disease (IBD), which is characterized by chronic inflammation of the small and large intestines. Due to complex interactions between multiple factors in the etiology of IBD, development of therapies that effectively maintain …

Confirmation Of A Causal Taar1 Allelic Variant In Addiction-Relevant Methamphetamine Behaviors, Tamara J Phillips, Tyler A. Roy, Sara J Aldrich, Harue Baba, Jason Erk, John R K Mootz, Cheryl Reed, Elissa J Chesler

Faculty Research 2021

Sensitivity to rewarding and reinforcing drug effects has a critical role in initial use, but the role of initial aversive drug effects has received less attention. Methamphetamine effects on dopamine re-uptake and efflux are associated with its addiction potential. However, methamphetamine also serves as a substrate for the trace amine-associated receptor 1 (TAAR1). Growing evidence in animal models indicates that increasing TAAR1 function reduces drug self-administration and intake. We previously determined that a non-synonymous single nucleotide polymorphism (SNP) in
