Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

Learning-based Techniques for Fast and Robust Motion Planning

Creator:: Chow, Scott
Abstract:: Motion planning is a cornerstone of autonomous robots, enabling robots to safely and efficiently perform tasks such as package delivery, infrastructure inspection, and manipulation. However, as the field of robotics matures, robotic systems are being developed that (1) are challenging to analytically model, (2) require computationally expensive model-based controllers, and...

The Viability of Container-Based Sanitation as a Tool for Sanitation Coverage in Urban Haiti

Creator:: VanRiper, Froggi Ramona
Abstract:: Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...

The Impact of Freeze-Thaw Cycles to the Physical and Biogeochemical Properties of Alaskan Permafrost Soils

Creator:: Rooney, Erin C.
Abstract:: Arctic warming is exposing thawing permafrost to repeated freeze-thaw, a disruptive process that can alter soil biogeochemistry and physical structure. To investigate the impact of permafrost exposure to freeze-thaw, soil response was tested across three scales: 2.5 cm³ aggregates, a forested hillslope, and two sites at contrasting latitudes. XCT imaging...

Characteristics of soil organic matter in two forest soils

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

Creator:: Zybach, Bob
Abstract:: The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

Action Segmentation in Videos: Deep Models, Prediction Diffusion, and Deep-Temporal Augmentations

Creator:: Aziere, Nicolas
Abstract:: This paper addresses the high model complexity and overconfident frame labeling of state-of-the-art (SOTA) action segmenters. Their complexity is typically justified by the need to sequentially refine action segmentation through multiple stages of a deep architecture. However, this multistage refinement does not take into account uncertainty of frame labeling predicted...

Effect of Oregon’s Coordinated Care Organizations on Healthcare Utilization and Maternal and Neonatal Outcomes Among Low-income Women with Chronic Mental-Physical Comorbidities

Creator:: Masoumirad, Mandana
Abstract:: Background: The number of people diagnosed with chronic physical conditions is increasing in the United States. Chronic mental illnesses are also common in the country. Low-income women and those on Medicaid bear a disproportionate burden of chronic conditions and these conditions significantly contribute to obstetric morbidity. Prioritizing preventive measures and...

Using DNA metabarcoding to describe biodiversity and disease dynamics

Creator:: Massey, Aimee L.
Abstract:: Land-use change, particularly in the form of the conversion of primary forest to forest-matrix systems, alters species communities and species interactions. Describing these often complex and nuanced species responses is one of the great challenges in ecology. Another complementary challenge is finding and using the most efficient means for collecting...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...
