Here we investigate sedimentary records from four small inland lakes located in the southern Cascadia forearc region for evidence of earthquakes. Three of these lakes are in the Klamath Mountains near the Oregon–California border, and one is in the central Oregon Coast range. The sedimentary sequences recovered from these lakes...
Nanostars have many potential applications, particularly in biomedicine, such as drug delivery, detection assays, and even cancer treatment. Seeing how their plasmon changes in response to changes to the environment of the nanostars can give us an insight to the stability of the nanostars. Our current studies involve the effect...
Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...
The purpose of this study was to evaluate the current status of the
implementation of Benin's new elementary science curriculum. The study
used the Concerns-Based Adoption Model (CBAM), a model designed to
evaluate the implementation of educational innovations. Specifically the
study attempted to ascertain teachers' concerns about the science curriculum,...
This dataset contains results from direct numerical simulations of premixed, three-dimensional, turbulent hydrogen/air flames, using the multicomponent and mixture-averaged diffusion models. In particular, this dataset contains information about the enstrophy budget and flame structure. We performed the simulations using the finite-difference code NGA; simulation details are described completely in the...
The eighth annual report details continued progress on each of the five
objectives. In this year's report, Objectives II and III from previous
reports have been combined to reflect the similarity of each effort.
Improved fumigants: The previously established field trials continue to
demonstrate the superior performance of both chioropicrin...
The expedient design of precision components in aerospace and other high-tech industries requires simulations of physical phenomena often described by partial differential equations (PDEs) without exact solutions. Modern design problems require simulations with a level of resolution difficult to achieve in reasonable amounts of time-even in effectively parallelized solvers. Though...
The condition of the sagebrush ecosystem has been declining in the Western United States, and greater sage-grouse (Centrocercus urophasianus), a sagebrush-obligate species, has experienced concurrent decreases in distribution and population numbers. This has prompted substantial research and management over the past two decades to improve the understanding of sage-grouse and...
Matlab code is included for detecting and tracking acoustic scattering layers from processed Echoview data. Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these...

Climate change is expected to change the distribution of species. For long-lived, sessile
species such as trees, tracking the warming climate depends on seedling colonization of
newly favorable areas. We compare the distribution of seedlings and mature trees for all but
the rarest tree species in California, Oregon and Washington,...
