Recent surges in suburbanization, population growth, and conservation funding have transformed the conservation landscape across the United States. Where once small local land trusts dominated the conservation community, ...
Modeling the effects of land use and land cover changes on water quality is important for watershed managers to better understand how human modifications to land surfaces may alter stream nutrient loads. One model available ...
<p>Most panel surveys are subject to missing data problems caused by panel attrition. The Additive Non-ignorable (AN) model proposed by Hirano et al. (2001) utilizes refreshment samples in panel surveys to impute missing ...
This study applies a discrete-continuous cohort model to US vehicle purchase decisions and
personal travel demand to describe the environmental and economic effects of a federal carbon
policy. The transportation sector ...
<p>Hundreds of different factors adorn the eukaryotic genome, binding to it in large number. These DNA binding factors (DBFs) include nucleosomes, transcription factors (TFs), and other proteins and protein complexes, ...
Nitrous oxide (N2O) is a potent greenhouse gas emitted from soils through the microbial processes of denitrification/nitrification. In agricultural soils these natural processes and thus N2O emission are significantly ...
<p>The demand for water and energy increases as the world's population grows. Unfortunately, many people have limited access to these two very necessary resources. In order to solve this dire issue, industry leaders, ...
<p>In our work we develop and analyze an ordinary differential equation</p><p>model that describes the cyclic adenosine monophosphate (cAMP) --Protein Kinase A (PKA) pathway in budding yeast. In particular our</p><p>model ...
<p>This dissertation focuses on solving some common problems associated with ecological field studies. In the core of the statistical methodology, lies spatial modeling that provides greater flexibility and improved ...
While terrestrial seasonal migrations worldwide continue to decline, the migrations of pronghorn antelope (Antilocapra americana) in the Northern Great Plains remain poorly studied. Development due to energy exploration ...
<p>The goal of this novel research effort was to address the impact that variations in a pre-selectable composition of a multi-agent system (MAS) can have on its resulting capabilities and performance while utilizing a ...
<p>Steady-state sound fields in enclosures, with specular and diffuse reflection boundaries, are modeled with a first-principle energy-intensity boundary element method using uncorrelated broadband directional sources. The ...
<p>In this thesis, temporal and spatial dependence are considered within nonparametric priors to help infer patterns, clusters or segments in data. In traditional nonparametric mixture models, observations are usually ...
The computational detection of regulatory elements in DNA is a difficult but important problem impacting our progress in understanding the complex nature of eukaryotic gene regulation. Attempts to utilize cross-species ...
Folates are a class of metabolites that are essential to living cells across all life. Because these molecules are especially important in aiding cell division, folates are targets for antibiotics, such as trimethoprim. I ...
This paper describes one method of modeling current and future market penetration of advanced lighting controls as a function of commercial floor space. We take advanced lighting controls to mean dimmers, photosensors, ...
The urban heat island effect is a phenomenon wherein the dark, hard surfaces prevalent in heavily-developed urban areas absorb and re-radiate heat, leading to measurably higher air temperatures in urban areas than in ...
<p>Many biological processes are effectively modeled as networks, but a frequent assumption is that these networks do not change during data collection. However, that assumption does not hold for many phenomena, such as ...
Power plants are significant capital investments whose returns are largely determined by such uncertain factors as future fuel prices and environmental regulations. Traditionally regulated utilities in the United States ...
Irregular flow and pressure have been observed in the nephrons of spontaneously hypertensive rats (SHR). Coupling of nephrons through their tubuloglomerular feedback (TGF) systems may be one of the factors involved in this ...
