Reactive-atom scattering dynamics and liquid-vacuum interfacial structure
(Montana State University - Bozeman, College of Letters & Science, 2019)Experiments to characterize reactive and nonreactive gas-liquid scattering dynamics were carried out with the use of a crossed molecular beams apparatus configured for beam-surface scattering. In each experiment, the ... -
Convolutional neural networks for multi- and hyper-spectral image classification
(Montana State University - Bozeman, Norm Asbjornson College of Engineering, 2019)While a great deal of research has been directed towards developing neural network architectures for classifying RGB images, there is a relative dearth of research directed towards developing neural network architectures ... -
Virus host interactions at the single cell level in hot springs of Yellowstone National Park
(Montana State University - Bozeman, College of Letters & Science, 2019)Viruses are the most abundant biological entities on the planet and virus-host interactions are some of the most important factors in shaping microbial community structure and function and global chemical cycling. The high ... -
With a little help from my friends: investigating communal mastery as a contributor to resilient outcomes among American Indians with substance use disorder
(Montana State University - Bozeman, College of Letters & Science, 2019)American Indians and Alaskan Natives (AI/ANs) have endured significant historical and individual adversity across several generations. Such adversity is associated with negative mental, physical, and behavioral outcomes. ... -
Mapping quantitative trait loci to understand seed size variation in Camelina sativa
(Montana State University - Bozeman, College of Agriculture, 2019)Camelina sativa (L.) Crantz is an emerging Brassica oilseed crop. Camelina oil is high in polyunsaturated C18-fatty acids and its uses range from bio-fuels and bio-lubricants to an animal feed additive and cooking oils. A ... -
Omics approaches identify molecular mechanisms of arsenic-microbial interactions
(Montana State University - Bozeman, College of Letters & Science, 2019)Arsenic is a class I carcinogen and causes various cancers and diseases. Its toxicity, prevalence, and potential for human exposure has classified arsenic as the number one environmental toxin according to the Environmental ... -
Spatiotemporal mapping of oxygen in model porous media biofilms using 19 F magnetic resonance oximetry
(Montana State University - Bozeman, Norm Asbjornson College of Engineering, 2019)Biofilms, microbial aggregates anchored to a surface using a sticky matrix of metabolic products called extracellular polymeric substances (EPS), are the dominant form of bacterial life and are widespread in nature, from ... -
The effects of climate-warming on solitary bees and their interactions with plants
(Montana State University - Bozeman, College of Letters & Science, 2019)The ecological consequences of anthropogenic climate-warming remain poorly understood for pollinators. In order to better understand these consequences, and thus the consequences of climate-warming for pollination services, ... -
Gastrointestinal organoid structure and transport
(Montana State University - Bozeman, Norm Asbjornson College of Engineering, 2019)Organoids are three-dimensional (3D) self-assembled, mammalian tissue cultures derived from stem cells that differentiate to contain multiple cell types. These cells spatially organize within the 3D structure and are capable ... -
Geomicrobiology of hydrogen in Yellowstone Hot Springs
(Montana State University - Bozeman, College of Letters & Science, 2019)Hydrogen (H 2) connects the geosphere and biosphere in rock-hosted ecosystems and has likely done so since early in Earth's history. High temperature hydrothermal environments, such as hot springs, can be enriched in H 2 ... -
Geochemical characterization of shallow sediments from the grounding zone of the Whillans Ice Stream
(Montana State University - Bozeman, College of Agriculture, 2019)The research presented in this thesis focused on subglacial flow beneath the West Antarctic Ice Sheet (WAIS) and its potential influence near the grounding zone. Antarctic grounding zones are of specific scientific interest ... -
Family environmental risk factors for adolescent substance use: an integrative review of the literature
(Montana State University - Bozeman, College of Nursing, 2019)Substance use continues to be an ongoing problem throughout the United States and worldwide. In terms of substance use initiation, adolescence is characterized as an especially vulnerable developmental time period. There ... -
Improving a precision agriculture on-farm experimentation workflow through machine learning
(Montana State University - Bozeman, Norm Asbjornson College of Engineering, 2019)Reducing environmental impact while simultaneously improving net return of crops is one of the key goals of Precision Agriculture (PA). To this end, an on-farm experimentation workflow was created that focuses on reducing ... -
Is habitat constraining bighorn sheep distribution and restoration: a case study in the Greater Yellowstone Ecosystem
(Montana State University - Bozeman, College of Letters & Science, 2019)Rocky Mountain Bighorn Sheep (Ovis canadensis) restoration continues to be a challenge throughout western North America despite nearly a century of efforts dedicated to the species' recovery. A persistent problem for ... -
Socialization experiences of STEM international graduate students at American public research universities: a multivariate analysis
