Using Spatial Resampling to Assess Redd Count Survey Length Requirements for Pacific Lamprey

Creator:: Mayfield, M. P., Schultz, L. D., Wyss, L. A., Colvin, M. E., and Schreck, C. B.
Abstract:: Pacific Lamprey Entosphenus tridentatus has declined across its range along the West Coast of North America, and an understanding of all life history phases is needed to address population recovery. Spawning surveys (redd counts) are common tools currently used to monitor returning adult salmonids, but such methodologies are in their...

Spawning Patterns of Pacific Lamprey in Tributaries to the Willamette River, Oregon

Creator:: Mayfield, M. P., Schultz, L. D., Wyss, L. A., Clemens, B. J., and Schreck, C. B.
Abstract:: Addressing the ongoing decline of Pacific Lamprey Entosphenus tridentatus across its range along the west coast of North America requires an understanding of all life history phases. Currently, spawning surveys (redd counts) are a common tool used to monitor returning adult salmonids, but the methods are in their infancy for...

Acoustic response of submarine volcanoes in the Tofua Arc and northern Lau Basin to two great earthquakes

Creator:: Bohnenstiehl, DelWayne R., Dziak, Robert P., Matsumoto, Haru, and Conder, James A.
Abstract:: Using a short-baseline hydrophone array, persistent volcanoacoustic sources are identified within the ambient noise field of the Lau Basin during the period between 2009 January and 2010 April. The submarine volcano West Mata and adjacent volcanic terrains, including the northern Matas and Volcano O, are the most active acoustic sources...

Methods for evaluating the impact of vertical programs on health systems: protocol for a study on the impact of the global polio eradication initiative on strengthening routine immunization and primary health care

Creator:: Closser, Svea, Rosenthal, Anat, Parris, Thomas, Maes, Kenneth, Justice, Judith, Cox, Kelly, Luck, Matthew A., Landis, R. Matthew, Grove, John, Tedoff, Pauley, Venczel, Linda, Nsubuga, Peter, Kuzara, Jennifer, and Neergheen, Vanessa
Abstract:: Background: The impact of vertical programs on health systems is a much-debated topic, and more evidence on this complex relationship is needed. This article describes a research protocol developed to assess the relationship between the Global Polio Eradication Initiative, routine immunization, and primary health care in multiple settings. Methods/Design: This...

Phenol formaldehyde adhesives formulated for advanced x-ray imaging in wood-composite bondlines

Creator:: Paris, Jesse L., Kamke, Frederick A., Mbachu, Reginald, and Gibson, Sara Kraushaar
Abstract:: A phenol formaldehyde (PF) adhesive was uniformly tagged with iodine such that it yielded sufficient x-ray computed tomography (XCT) gray-scale contrast for material segmentation in reconstructed wood-composite bondlines. Typically, untagged adhesives are organic and have a similar solid state density as wood cell-walls, and therefore cannot be segmented quantitatively in...

Development of the Global Earthquake Model's neotectonic fault database

Creator:: Christophersen, Annemarie, Litchfield, Nicola, Berryman, Kelvin, Yeats, Robert, Thomas, Richard, Basili, Roberto, Wallace, Laura, Ries, William, Hayes, Gavin P., Haller, Kathleen M., Yoshioka, Toshikazu, Koehler, Richard D., Clark, Dan, Wolfson-Schwehr, Monica, Boettcher, Margaret S., Villamor, Pilar, Horspool, Nick, Ornthammarath, Teraphan, Zuniga, Ramon, Langridge, Robert M., Stirling, Mark W., Goded, Tatiana, Costa, Carlos, and Yeats, Robert
Abstract:: The Global Earthquake Model (GEM) aims to develop uniform, openly available, standards, datasets and tools for worldwide seismic risk assessment through global collaboration, transparent communication and adapting state-of-the-art science. GEM Faulted Earth (GFE) is one of GEM’s global hazard module projects. This paper describes GFE’s development of a modern neotectonic...

Adapting to Climate Change on Western Public Lands: Addressing the Ecological Effects of Domestic, Wild, and Feral Ungulates

Creator:: Beschta, Robert L., Donahue, Deborah L., DellaSala, Dominick A., Rhodes, Jonathan J., Karr, James R., O'Brien, Mary H., Fleischner, Thomas L., and Deacon-Williams, Cindy
Abstract:: Climate change affects public land ecosystems and services throughout the American West and these effects are projected to intensify. Even if greenhouse gas emissions are reduced, adaptation strategies for public lands are needed to reduce anthropogenic stressors of terrestrial and aquatic ecosystems and to help native species and ecosystems survive...

Image processing of multiphase images obtained via X-ray microtomography: A review

Creator:: Schlüter, Steffen, Sheppard, Adrian, Brown, Kendra, and Wildenschild, Dorthe
Abstract:: Easier access to X-ray microtomography (lCT) facilities has provided much new insight from high-resolution imaging for various problems in porous media research. Pore space analysis with respect to functional properties usually requires segmentation of the intensity data into different classes. Image segmentation is a nontrivial problem that may have a...
