Geomorphic Evidence for Differential Rock Uplift Across the Southern Cascadia Forearc

Creator:: von Dassow, Wesley
Abstract:: The nature of upper plate deformation along the Cascadia subduction zone (CSZ) is poorly understood. Systematic covariation among topographic relief, geodetically determined uplift rates, decadal to millennial erosion rates, and the frequency of episodic tremor and slip (ETS) along the Cascadia forearc suggest a genetic association between forearc topography and...

The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

Creator:: Myers, Conner J.
Abstract:: In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...

Diffusion-free Grotthuss topochemistry for high-rate and long-life proton batteries

Creator:: Wu, Xianyong, Hong, Jessica J., Shin, Woochul, Ma, Lu, Liu, Tongchao, Bi, Xuanxuan, Yuan, Yifei, Qi, Yitong, Surta, T. Wesley, Huang, Wenxi, Neuefeind, Joerg, Wu, Tianpin, Greaney, P. Alex, Lu, Jun, and Ji, Xiulei
Abstract:: The design of Faradaic battery electrodes that exhibit high rate capability and long cycle life equivalent to those of the electrodes of electrical double-layer capacitors is a big challenge. Here we report a strategy to fill this performance gap using the concept of Grotthuss proton conduction, in which proton transfer...

Can Observation Skills of Citizen Scientists Be Estimated Using Species Accumulation Curves?

Creator:: Kelling, Steve, Johnston, Alison, Hochachka, Wesley M., Iliff, Marshall, Fink, Daniel, Gerbracht, Jeff, Lagoze, Carl, La Sorte, Frank A., Moore, Travis, Wiggins, Andrea, Wong, Weng-Keen, Wood, Chris, and Yu, Jun
Abstract:: Volunteers are increasingly being recruited into citizen science projects to collect observations for scientific studies. An additional goal of these projects is to engage and educate these volunteers. Thus, there are few barriers to participation resulting in volunteer observers with varying ability to complete the project’s tasks. To improve the...

Effects of fuel content and density on the smoldering characteristics of cellulose and hemicellulose

Creator:: Smucker, Benjamin D., Mulky, Tejas C., Cowan, Daniel A., Niemeyer, Kyle E., and Blunck, David L.
Abstract:: Smoldering combustion in wildland fires poses hazards for both ecosystems and humans by destroying biomass, transitioning to flaming combustion, and releasing significant quantities of pollution. Understanding the parameters that control smoldering is necessary to help predict and potentially mitigate these hazards. A challenge in identifying these parameters is the wide...

Animal Pointing: Changing Trends and Findings From 30 Years of Research

Creator:: Krause, Mark A., Udell, Monique A. R., Leavens, David A., and Skopos, Lyra
Abstract:: The past 30 years have witnessed a continued and growing interest in the production and comprehension of manual pointing gestures in nonhuman animals. Captive primates with diverse rearing histories have shown evidence of both pointing production and comprehension, though there certainly are individual and species differences, as well as substantive...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Mock modularity of the M-d-rank of overpartitions

Creator:: Jennings-Shaffer, Chris and Swisher, Holly
Abstract:: We investigate the modular properties of a new partition rank, the M-d-rank of overpartitions. In fact this is an infinite family of ranks, indexed by the positive integer d, that gives both the Dyson rank of overpartitions and the overpartition M-2-rank as special cases. The M-d-rank of overpartitions is the...

Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

Creator:: Trobough, Nathaniel D.
Abstract:: This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

Dissolved Organic Carbon Production and Flux from Long Term Litter Manipulations in a Pacific Northwest Old-Growth Forest

Creator:: Evans, Lucas R.
Abstract:: Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...
