Synthesis of α-Ketoester- and α-Hydroxyester-Substituted Isoindazoles via the Thermodynamic Coarctate Cyclization of Ester-Terminated Azo-Ene-Yne Systems

Creator:: McClintock, Sean P., Forster, Nathan, Herges, Rainer, and Haley, Michael M.
Abstract:: The synthesis of isoindazoles bearing α-ketoester and α-hydroxyester groups via the coarctate cyclization of ester terminated azo-ene-yne precursors is described. Whereas previous studies on isoindazole formation have shown the reaction to proceed through a kinetic coarctate pathway, functionalization of the terminal acetylene with a methyl ester sufficiently stabilizes the carbene...

Comparison of in situ measurements of cirrus cloud ice water content

Creator:: Davis, Sean M., Avallone, Linnea M., Weinstock, Elliot M., Twohy, Cynthia, Smith, Jessica B., and Kok, Gregory L.
Abstract:: Aircraft-based in situ measurements of cirrus cloud ice water content (IWC) are important for cloud microphysical/radiative modeling and satellite validation studies, yet the measurements have proven challenging due, in part, to the large dynamic range of IWC values present in cirrus clouds. To date, three instruments designed for the measurement...

Remodeling of skeletal muscle mitochondrial proteome with high-fat diet involves greater changes to beta-oxidation than electron transfer proteins in mice

Creator:: Dasari, Surendra, Newsom, Sean A., Ehrlicher, Sarah E., Stierwalt, Harrison D., and Robinson, Matthew M.
Abstract:: Excess fat intake can increase lipid oxidation and expression of mitochondrial proteins, indicating remodeling of the mitochondrial proteome. Yet intermediates of lipid oxidation also accumulate, indicating a relative insufficiency to completely oxidize lipids. We investigated remodeling of the mitochondrial proteome to determine mechanisms of changes in lipid oxidation following high-fat...

The role of remote sensing in process-scaling studies of managed forest ecosystems

Creator:: Masek, Jeffrey G., Hayes, Daniel J., Hughes, M. Joseph, Healey, Sean P., and Turner, David P.
Abstract:: Sustaining forest resources requires a better understanding of forest ecosystem processes, and how management decisions and climate change may affect these processes in the future. While plot and inventory data provide our most detailed information on forest carbon, energy, and water cycling, applying this understanding to broader spatial and temporal...

Primary Intestinal and Vertebral Chordomas in Laboratory Zebrafish (Danio rerio)

Creator:: Cooper, Timothy K., Murray, Katrina N., Spagnoli, Sean, and Spitsbergen, Jan M.
Abstract:: Chordomas are uncommon neoplasms arising from notochord remnants, most commonly occurring in the axial skeleton. Extraskeletal soft tissue chordomas are rare primary tumors, and primary intestinal chordomas have not been reported. Herein we report 24 cases of spontaneous primary intestinal chordomas in zebrafish, as well as 9 spontaneous vertebral chordomas....

Chronic exposure of killifish to a highly polluted environment desensitizes estrogen–responsive reproductive and biomarker genes

Creator:: Bugel, Sean M., Bonventre, Josephine A., White, Lori A., Tanguay, Robert L., and Cooper, Keith R.
Abstract:: Reproductive and endocrine disruption is commonly reported in aquatic species exposed to complex contaminant mixtures. We previously reported that Atlantic killifish (Fundulus heteroclitus) from the chronically contaminated Newark Bay, NJ, exhibit multiple endocrine disrupting effects, including inhibition of vitellogenesis (yolk protein synthesis) in females and false negative vitellogenin biomarker responses...

A framework for estimating potential fluid flow from digital imagery

Creator:: Luttman, Aaron, Bollt, Erik M., Basnayake, Ranil, Kramer, Sean, and Tufillaro, Nicholas B.
Abstract:: Given image data of a fluid flow, the flow field, < u, v >, governing the evolution of the system can be estimated using a variational approach to optical flow. Assuming that the flow field governing the advection is the symplectic gradient of a stream function or the gradient of...

Structural and magnetic investigation of Fe3+ and Mg2+ substitution into the trigonal bipyramidal site of InGaCuO4

Creator:: Grajczyk, Rosa, Berthelot, Romain, Muir, Sean, Sleight, A. W., and Subramanian, M. A.
Abstract:: The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were synthesized and characterized through the use of X – ray and neutron diffraction, and DC – magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...

Asphaltum hafting and projectile point durability: an experimental comparison of three hafting methods

Creator:: Fauvelle, Mikael, Smith, Erin M., Brown, Sean H., and Des Lauriers, Matthew R.
Abstract:: The design of a projectile delivery system often plays a critical role in the durability and breakage patterns associated with spent projectile points. This paper presents the results of an experimental project designed to examine projectile point durability and breakage patterns between three different hafting methods. Specifically, we compare two...

Effects of height imputation strategies on stand volume estimation

Creator:: Garber, Sean M., Temesgen, Hailemariam, Monleon, Vicente J., and Harm, David W.
Abstract:: Subsampling and subsequent imputation of tree heights can improve the predictive performance of stand volume estimation but may also introduce biases. Using coastal Douglas-fir data from southwest Oregon, USA, the predictive performance of several height imputation strategies for estimating stand volume was evaluated. A subsample of 1-15 trees was randomly...
