The buildup of reactive oxygen species (ROS) and reactive nitrogen and oxygen species (RNS) is known as oxidative stress. Oxidative stress results in a wide variety of modification to biological macromolecules including nucleic acids, lipids, and proteins. For at least 30 years it has been known that high levels of...
Modern supply chains have grown to be far more complex than their predecessors, as global trade and accessibility have opened avenues of trade that were previously impossible. As such, the inherent risk of internal and/or external disruptions impacting the performance of a supply chain has also grown due to the...
The restoration of rivers and streams should be based on a
strong conceptual framework. Streams are developing systems. As
such, streams exhibit temporal behaviors that change with changing
stream environments. Underlying the dynamic development of streams is
potential capacity. Streams express this capacity as an array of
habitats over time...
Anisogramma anomala causes a stem canker of filberts, Corylus avellana. This disease became a threat to the main U.S. filbert growing region when it was introduced into the Pacific Northwest around 1968. Various methods of artificially inoculating filbert trees and seeds were explored. Less than 1% of potted filbert trees...

The work presented in this thesis deals with the mechanisms by which a vibrationally excited diatomic molecule gives up its energy to a host monatomic lattice at low temperature. The vibrational lifetimes (v"=1) of the metal oxides Ba0 and A10 in their ground electronic states are studied using pulsed dual...
Monophyly of the gomphoid-phalloid clade was confirmed based on multigene phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales and Phallales) were also demonstrated to be monophyletic. The interrelationships among the subclades were, however, not resolved, and alternative topologies could not be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...
Stratigraphy and chronology are essential to sedimentological study of Earth system histories. And, stratigraphy and chronology are often challenging and interesting problems themselves. The Quaternary (2.588 Ma - present) experienced paleoenvironmental and paleo-geomagnetic variability well outside the range of the recent instrumental record, providing the opportunity to place recent observations...
Worldwide, many organizations are pursuing higher energy efficiency by reducing power consumption of their processes, systems, and supporting infrastructure. The rapid growth of the information technology (IT) industry and the miniaturization of semiconductors have resulted in substantial increases in energy consumption and power density of IT equipment, and, subsequently, heat...
In this work we present a multiagent Fleet Coordination Problem (FCP).

Cooperative multiagent systems are used as solution concepts in many application domains including air traffic control, satellite communications, and extra planetary exploration. As systems become more distributed and complex, we observe three phenomena. First, these systems cannot be accurately modeled, rendering traditional model based control methods inadequate. Second, system parameters...
In an age of increasing complexity, simple answers no longer suffice, but the demand for greater sophistication
is itself at odds with an era of growing specialization. Researchers must thus incorporate information from specialists in
other fields. This trend in interdisciplinary research contains hidden challenges, however, including a necessary familiarity...
The deglacial behavior of the sub-Arctic North Pacific is poorly constrained, with many published records suffering from limited age control due to extensive post- depositional biogenic carbonate dissolution. Potential alternative dating methods could include the correlation of stable-isotopic and/or paleomagnetic secular variation records to an independently-dated regional template, however no...
