Whole ecosystem carbon dioxide (CO₂) exchange estimated with the eddy covariance (EC) technique has been central to studies on the responses of terrestrial ecosystems to disturbance and intra‐annual and interannual variations in climate, but challenges exist in understanding and reducing the uncertainty in estimates of net ecosystem exchange (NEE) of...
Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...
Aerosol concentrations and 3-D winds were measured from 9 to 25 September 2007, above a pine forest in California. The measurements were combined using the eddy covariance (EC) technique to determine aerosol eddy fluxes as a function of particle diameter within the accumulation mode size range (0.25 μm≤D[subscript]p≤1 μm here)....
Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...
Three stations, at similar to ~80 m water depth on the Oregon shelf between 44.7 degrees N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an...
Environmental factors such as temperature, air, and water can have a profound
effect on the durability of asphalt concrete mixtures. In mild climates where good
quality aggregates and asphalt cement are available, the major contribution to
deterioration may be due to traffic loading and the resultant distress is manifested

This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...
Terrestrial biosphere models can help identify physical processes that control carbon
dynamics, including land–atmosphere CO₂ fluxes, and have great potential to predict the terrestrial
ecosystem response to changing climate. The skill of models that provide continental-scale carbon flux
estimates, however, remains largely untested. This paper evaluates the performance of continental-scale...
The peripheral-type benzodiazepine receptor (PTBR) of trout brain was
pharmacologically characterized and pyrethroid interaction with this site
investigated. High-affinity binding sites for [³H]PK 11195 were detected in brain
membranes of rainbow trout; these shared some of the characteristics of the
PTBR of rodent brain (i.e., high affinity for PK 11195...

Most experiments were designed as randomized complete blocks with two to five replications. Herbicide. treatments were applied uniformly with precision plot sprays or granular formulations were distributed...
Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...
Phytophthora infestans is a destructive plant pathogen best known
for causing the disease that triggered the Irish potato famine and
remains the most costly potato pathogen to manage worldwide.

understanding the mechanisms of repeated global emergence of
this pathogen....
The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...

The computation of the inverse of a number in finite fields, namely Galois Fields GF(p) or GF(2ⁿ), is one of the most complex arithmetic operations in cryptographic applications. In this work, we investigate the GF(p) inversion and present several phases in the design of efficient hardware implementations to compute the...

Bats play an important role in controlling insect populations. In North America, bats are the primary predators of night-flying insects. Some species of bats can capture several hundred insects an hour, including insect species that can devastate valuable plants or crops.
This classification is an update of the 2004 classification of native vegetation of Oregon by Kagan, Christy, Murray and Titus. As before, this classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were part of the presettlement landscape of...
We compare the Landauer, Kubo, and microcanonical [J. Phys.: Condens. Matter 16, 8025 (2005)] approaches
to quantum transport for the average current, the entanglement entropy, and the semiclassical full-counting
statistics (FCS). Our focus is on the applicability of these approaches to isolated quantum systems such as
ultracold atoms in engineered...
NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...

Hop is one of the few dioecious plants with dimorphic sex chromosomes. Because the entire Cannabaceae family is dioecious, hop and other members of this family are thought to have a relatively older sex chromosomal system than other plant species. Hop cones are only produced in female hops with or...

A digital phase locked loop (DPLL) and a statistical time-to-digital converter (STDC) were previously fabricated in a 0.35µm, 3.3V SOI CMOS process. This work summarizes these designs and characterizes the measured performance. Simulations supplement the measurements where applicable.
The DPLL was found to reach a locked state under a limited...
Physical activity recognition using accelerometer data is a rapidly emerging field with many real-world applications. Much of the previous work in this area has assumed that the accelerometer data has already been segmented into pure activities, and the activity recognition task has been to classify these segments. In reality, activity...
