Classifying Octonionic-Linear Operators

Creator:: Putnam, Alexander
Abstract:: The goal of this paper is to classify linear operators with octonionic coefficients and octonionic variables. While building up to the octonions we also classify linear operators over the quaternions and show how to relate the linear operators over the quaternions and octonions to matrices. We also construct a basis...

Selfish Little Circles: Transmission Bias and Evolution of Large Deletion-Bearing Mitochondrial DNA in Caenorhabditis briggsae Nematodes

Creator:: Clark, Katie A., Howe, Dana K., Gafner, Kristin, Kusuma, Danika, Ping, Sita, Estes, Suzanne, and Denver, Dee R.
Abstract:: Selfish DNA poses a significant challenge to genome stability and organismal fitness in diverse eukaryotic lineages. Although selfish mitochondrial DNA (mtDNA) has known associations with cytoplasmic male sterility in numerous gynodioecious plant species and is manifested as petite mutants in experimental yeast lab populations, examples of selfish mtDNA in animals...

A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Creator:: Wasowski, Ronald, Alexander, David, Kolmes, Steven, Banet, Nathan, Card, Amy, Haines, Morgan, Kolmes, Elijah, Northcutt, Kelly, Roemer, Derek, and Webber, Sarah
Abstract:: Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers...

The Genome of Tolypocladium inflatum: Evolution, Organization, and Expression of the Cyclosporin Biosynthetic Gene Cluster

Creator:: Bushley, Kathryn E., Raja, Rajani, Jaiswal, Pankaj, Cumbie, Jason S., Nonogaki, Mariko, Boyd, Alexander E., Owensby, C. Alisha, Knaus, Brian J., Elser, Justin, Miller, Daniel, Di, Yanming, McPhail, Kerry L., and Spatafora, Joseph W.
Abstract:: The ascomycete fungus Tolypocladium inflatum, a pathogen of beetle larvae, is best known as the producer of the immunosuppressant drug cyclosporin. The draft genome of T. inflatum strain NRRL 8044 (ATCC 34921), the isolate from which cyclosporin was first isolated, is presented along with comparative analyses of the biosynthesis of...

Palaeo-sea-level and palaeo-ice-sheet databases: problems, strategies, and perspectives

Creator:: Düsterhus, André, Rovere, Alessio, Carlson, Anders E., Horton, Benjamin P., Klemann, Volker, Tarasov, Lev, Barlow, Natasha L. M., Bradwell, Tom, Clark, Jorie, Dutton, Andrea, Gehrels, W. Roland, Hibbert, Fiona D., Hijma, Marc P., Khan, Nicole, Kopp, Robert E., Sivan, Dorit, and Törnqvist, Torbjörn E.
Abstract:: Sea-level and ice-sheet databases have driven numerous advances in understanding the Earth system. We describe the challenges and offer best strategies that can be adopted to build self-consistent and standardised databases of geological and geochemical information used to archive palaeo-sea-levels and palaeo-ice-sheets. There are three phases in the development of...

Phylogeny of minute carabid beetles and their relatives based upon DNA sequence data (Coleoptera, Carabidae, Trechitae)

Creator:: Maddison, David R. and Ober, Karen A.
Abstract:: The phylogeny of ground beetles of supertribe Trechitae is inferred using DNA sequences of genes that code for 28S ribosomal RNA, 18S ribosomal RNA, and wingless. Within the outgroups, austral psydrines are inferred to be monophyletic, and separate from the three genera of true Psydrina (Psydrus, Nomius, Laccocenus); the austral...

Farm Zoning and Fairness in Oregon 1964 - 2014

Creator:: Richmond, Henry R. and Houchen, Timothy G.
Abstract:: Senate Bill 100 (1973) and the Oregon Land Conservation and Development Commission’s (LCDC) goals (1975) required: - Cities to adopt urban growth boundaries (UGBs) to contain sprawl, and - Counties to use zoning to limit 15.6 million acres of farmland to farm use, and 8.0 million acres of forest land...

A potential implicit particle method for high-dimensional systems

Creator:: Weir, B., Miller, R. N., and Spitz, Y. H.
Abstract:: This paper presents a particle method designed for high-dimensional state estimation. Instead of weighing random forecasts by their distance to given observations, the method samples an ensemble of particles around an optimal solution based on the observations (i.e., it is implicit). It differs from other implicit methods because it includes...

Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...

In Vivo Quantification Reveals Extensive Natural Variation in Mitochondrial Form and Function in Caenorhabditis briggsae

Creator:: Hicks, Kiley A., Howe, Dana K., Leung, Aubrey, Denver, Dee R., and Estes, Suzanne
Abstract:: In We have analyzed natural variation in mitochondrial form and function among a set of Caenorhabditis briggsae isolates known to harbor mitochondrial DNA structural variation in the form of a heteroplasmic nad5 gene deletion (nad5 Delta) that correlates negatively with organismal fitness. We performed in vivo quantification of 24 mitochondrial...
