Modeling cellular metabolism in multiple scales
… within relevant biological time and length scales. Despite recent advances QM calculations, the computational cost of studying nanosecond-long dynamics of entire systems relying solely on QM methodologies is prohibitive. To circumvent this cost barrier, it is possible to confine the QM …

ECOLOGY AND COEXISTENCE OF SCAPHIRHYNCHUS STURGEON AT MULTIPLE SCALES
… sturgeon ecology and coexistence at multiple scales. I first examined the environmental life history of pallid and shovelnose sturgeon within the Mississippi River basin (Chapter 2). Using microchemistry techniques, my goal was to assess how to improve species conservation by …

Characterizing cobalamin cycling by Antarctic marine microbes across multiple scales
… cobalamin cycling in Antarctic seas across multiple spatiotemporal scales. I conducted laboratory culture experiments with complementary proteomics and transcriptomics to investigate the B12-ecophysiology of P. antarctica strain CCMP 1871 morphotypes under iron-B12 co-limitation. We observed …

Applications of Imaging Spectroscopy in Forest Ecosystems at Multiple Scales
… pine nutrient status at the leaf and canopy scales, respectively. The first study determined that loblolly pine foliar macronutrient concentrations can be successfully modeled across the Southeastern US (R2=0.39-0.74). Following on these results, the second study focused on the relationship …

Interactions Between Dust and Ecosystem, and Landscape at Multiple Scales
… conditions by integrating information across multiple scales. Specifically, three research projects are pursued. First, the modulation of dust emissions by non-photosynthetic vegetation (NPV) is evaluated by implementing a satellite-based total vegetation dataset, which includes NPV, into a …

Simulating Urban Landscape Transformation: Implications for Urban Wetlands at Multiple Scales
… of the change on wetlands at various spatial scales within the study area. To achieve this, the study was divided into three parts. The first part examined how significant the impacts of classification methods of input land cover maps are on the overall accuracy of the urban land change …

Habitat selection by the elegant trogon (Trogon elegans) at multiple scales.
… by the trogon from 1993 to 1995 at three spatial scales (those of the mountain and canyon, home range, and microsite scales). At the broadest (inter-mountain and inter-canyon) scale, trogons were positively associated with cover by sycamore, pinyon, and juniper vegetation, and the abundances of …

Analytical and experimental studies of plant-flow interaction at multiple scales
Across scales ranging from individual blades to river reaches, the interaction between water flow and vegetation has important ecological and engineering implications. At the reach-scale, vegetation is often the largest source of hydraulic resistance. Based on a simple momentum balance, we show …

A computational study of the origin of brain oscillations at multiple scales
Brain activity recordings from multiple locations from the brain at rest often demonstrate dynamic spatiotemporal reconfigurations of oscillatory activity. These oscillatory patterns are observed both using indirect recordings of neural activity, such as resting-state functional magnetic resonance …

Energy Cultures: An Approach to Explore Workplace Energy Use at Multiple Scales
Industry is attempting to meet its greenhouse gas emission targets by implementing energy efficiency measures. Technological solutions are often employed through the provision of onsite energy generation and improvements in heating and ventilation systems, despite Janda’s (2000) observation that …

From Protein Folds to Chromatin: Topological Data Analysis and Deep Learning at Multiple Scales
Across biological scales—from atomic-level protein folds to the three-dimensional architecture of chromatin—structural organization governs molecular function and regulation. We present two complementary computational frameworks that integrate geometric, topological, and spatial modeling with deep …

The Ecological Niche of Darters (Pisces:Percidae) Across Multiple Scales in the Ohio River Basin
… the resource utilization of species at local scales (significant in 30 of 33 comparisons) and unrelated species caused shifts in darter resource utilization by competing for the same resources. In my second study, I broadened the geographic scale to study intraspecific interactions among …

Field Theory: the study of lattice systems created through modular paneling transcending multiple scales
… of project type and scale. Decisions are made at multiple scales, starting with the human and working up to the building scale, as well as the realm of possibilities that fall in between. The module is acting as a matrix which regulates the articulation every architectural element. It creates …

Landscape heterogeneity at multiple scales: effects on movement patterns and habitat selection of eleodid beetles
I combined observational studies with field experiments to investigate how landscape heterogeneity influences habitat selection in eleodid beetles of the shortgrass prairie of Colorado. I examined correlations in spatio-temporal patterns of habitat occupancy, population density, and community …
