Do Douglas-fir branches and roots have juvenile wood?

Creator:: Peterson, M. G., Dietterich, H. R., and Lachenbruch, Barbara
Abstract:: We sampled boles, branches, and roots of four Douglas-fir (Pseudotsuga menziesii var. menziesii) trees to learn a) whether branches and roots have a zone of juvenile wood, defined as a zone with progressive changes in wood density and/or tracheid length from the pith outward at successively greater cambial ages, and...

PAC Optimal MDP Planning with Application to Invasive Species Management

Creator:: Taleghan, Majid Alkaee, Dietterich, Thomas G., Crowley, Mark, Hall, Kim, and Albers, H. Jo
Abstract:: In a simulator-defined MDP, the Markovian dynamics and rewards are provided in the form of a simulator from which samples can be drawn. This paper studies MDP planning algorithms that attempt to minimize the number of simulator calls before terminating and outputting a policy that is approximately optimal with high...

Allowing a wildfire to burn: estimating the effect on future fire suppression costs

Creator:: Houtman, Rachel M., Montgomery, Claire A., Gagnon, Aaron R., Calkin, David E., Dietterich, Thomas G., McGregor, Sean, and Crowley, Mark
Abstract:: Where a legacy of aggressive wildland fire suppression has left forests in need of fuel reduction, allowing wildland fire to burn may provide fuel treatment benefits, thereby reducing suppression costs from subsequent fires. The least-cost-plus-net-value-change model of wildland fire economics includes benefits of wildfire in a framework for evaluating suppression...

Reconstructing Velocities of Migrating Birds from Weather Radar – A Case Study in Computational Sustainability

Creator:: Farnsworth, Andrew, Sheldon, Daniel, Geevarghese, Jeffrey, Irvine, Jed, Van Doren, Benjamin, Webb, Kevin, Dietterich, Thomas G., and Kelling, Steve
Abstract:: Bird migration occurs at the largest of global scales, but monitoring such movements can be challenging. In the US there is an operational network of weather radars providing freely accessible data for monitoring meteorological phenomena in the atmosphere. Individual radars are sensitive enough to detect birds, and can provide insight...

bayesclust: An R Package for Testing and Searching for Significant Clusters

Creator:: Gopal, Vikneswaran, Fuentes, Claudio, and Casella, George
Abstract:: The detection and determination of clusters has been of special interest among researchers from different fields for a long time. In particular, assessing whether the clusters are significant is a question that has been asked by a number of experimenters. In Fuentes and Casella (2009), the authors put forth a...

An integrated approach to historical population assessment of the great whales: case of the New Zealand southern right whale

Creator:: Jackson, Jennifer A., Carroll, Emma L., Smith, Tim D., Zerbini, Alexandre N., Patenaude, Nathalie J., and Baker, C. Scott
Abstract:: Accurate estimation of historical abundance provides an essential baseline for judging the recovery of the great whales. This is particularly challenging for whales hunted prior to twentieth century modern whaling, as population-level catch records are often incomplete. Assessments of whale recovery using pre-modern exploitation indices are therefore rare, despite the...

Inequivalent Cantor sets in 𝑅³ whose complements have the same fundamental group

Creator:: Garity, Dennis J. and Repovš, Dušan
Abstract:: For each Cantor set C in R³, all points of which have bounded local genus, we show that there are infinitely many inequivalent Cantor sets in R³ with the complement having the same fundamental group as the complement of C. This answers a question from Open Problems in Topology and...

Topotactic Reduction and Reoxidation of Hexagonal RCu0.5Ti0.5O3 (R =Y, Eu-Lu) Phases

Creator:: Jiang, Peng, Berthelot, Romian, Li, Jun, Sleight, A. W., and Subramanian, M. A.
Abstract:: Hexagonal AMO₂ and AMO₃ phases have the same basic structure, and intermediate compositions for this structure have been prepared by topotactic oxidation of AMO₂ phases such as RCuO₂, where R is a trivalent rare earth cation. We now find that such intermediate phases can also be prepared by topotactic reduction...

Two-phase flow regimes of condensing R-134a at low mass flux in rectangular microchannels

Creator:: Vanderputten, Michael A., Jacob, Tabeel A., Sattar, Maria, Ali, Nouman, and Fronk, Brian M.
Abstract:: Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...
