Cellular sets in the Hilbert cube are the intersection of nested sequences of normal
cubes. One way of getting cellular maps on the Hilbert cube is by decomposing the Hilbert
cube into cellular sets and using a quotient map. By using a cellular decomposition of the
Hilbert cube, an example...
Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp ‘‘tropopause.’’ In the tropics, this layer is often called the ‘‘tropical tropopause layer’’ (TTL). We present an overview of observations in the TTL and discuss...
Carbon dioxide (CO₂) fluxes between the ocean and atmosphere on continental margins are difficult to diagnose because these regions experience large variability over spatial and temporal scales spanning meters to basins and hours to years, respectively. In a global sense, continental margins could represent a significant atmospheric CO₂ sink, equivalent...
Indole-3-carbinol (I3C) and butylated hydroxyanisole (BHA), anti-carcinogens
present in the human diet, were tested for their in vivo
and in vitro effect on aflatoxin B₁. (AFB₁) metabolism, and DNA adduct
formation in the rainbow trout. Dietary BHA at either 0.3 or 0.03%
had no effect on the hepatic tumor incidence...
Jordan has a higher fertility rate (3.8) than the averages of countries similar in income to Jordan (2.2) and compared to the Middle East and North Africa region as a whole (2.8) (WHO, WB, UNICEF, & DHS, 2011). The findings of the 2009 Jordanian Population and Family Health Survey demonstrated...

We report results from an oyster hatchery on the Oregon coast, where intake waters experienced variable carbonate chemistry (aragonite saturation state < 0.8 to > 3.2; pH < 7.6 to > 8.2) in the early summer of 2009. Both larval production and midstage growth (∼ 120 to ∼ 150 µm)...
Declarative visual programming languages (VPLs), including spreadsheets, make up a large portion of both research and commercial VPLs. Spreadsheets in particular enjoy a wide audience, including end users. Unfortunately, spreadsheets and most other declarative VPLs still suffer from some of the problems that have been solved in other languages, such...
Most climate change predictions focus on the response of individual species to changing local conditions and ignore species interactions, largely due to the lack of a sound theoretical foundation for how interactions are expected to change with climate and how to incorporate them into climate change models. Much of the...
Vibrio tubiashii has been linked to disease outbreaks in molluscan species, including oysters, geoducks, and clams. In particular, oyster hatcheries in the Pacific Northwest have been plagued by intermittent vibriosis since 2006. Accurate detection of vibrios, including V. tubiashii, is critical to the hatcheries in order to allow for rapid...
In this thesis I present the choice calculus, a formal language for representing variation in software and other structured artifacts. The choice calculus is intended to support variation research in a way similar to the lambda calculus in programming language research. Specifically, it provides a simple formal basis for presenting,...
Abstract: Coastal upwelling zones may be at enhanced risk from ocean acidification as upwelling brings low aragonite saturation state (Ω[subscript Ar]) waters to the surface that are further suppressed by anthropogenic CO₂. Ω[subscript Ar] was calculated with pH, pCO₂, and salinity-derived alkalinity time series data from autonomous pH and pCO₂...
An on-line trace enrichment (TE) system, based on high pressure
liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has
been developed for trace metal analysis. The sample is pumped through
a column filled with a cation exchange resin which traps metal ions.
The ions are subsequently stripped from the column...
This paper investigates the benefit of various parallel processing
architectures for a Command and Control system for the Royal
Thai Air Force. Parallel processing has been shown to be useful
for air defense and air traffic control applications. Its advantages
are examined within the constraint imposed by the available
resources...
Novel broad-spectrum antimicrobials are a critical component of a strategy for combating antibiotic-resistant pathogens. In this
study, we explored the activity of the broad-spectrum antiviral compound ST-669 for activity against different intracellular bacteria
and began a characterization of its mechanism of antimicrobial action. ST-669 inhibits the growth of three different...
Our laboratory is exploring the mechanism of action of a novel broad spectrum antiviral, ST-669. This compound has activity against a variety of different viruses and the obligate intracellular bacterium, Chlamydia. In this study, we explored the effects of ST-669 when the cell cycle of the host cells was altered....
Our laboratory group is studying the molecular target of a novel, broad-spectrum antiviral compound known as ST-669. This compound has activity against a variety of different viruses and also obligate intracellular bacteria in the genera Coxiella and Chlamydia. The goal of this thesis project was to help elucidate the mechanism...
Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

Although machine learning systems are often effective in real-world applications, there are situations in which they can be even better when provided with some degree of end user feedback. This is especially true when the machine learning system needs to customize itself to the end user's preferences, such as in...
Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...
