Investing in farmland is one of the most important decisions that
farmers face in their lifetimes. Usually, large amounts of debt are
required to purchase a substantial tract of land, thereby reducing the
farmer's liquidity position and future borrowing capacity. Fixed debt
commitments must be met by highly variable future...
Systems that can learn interactively from their end-users are quickly becoming widespread. Until recently, this progress has been fueled mostly by advances in machine learning; however, more and more researchers are realizing the importance of studying users of these systems. In this article we promote this approach and demonstrate how...
I classified the environment of the Klamath Mountains region into physical habitat types using climate and soil variables and a geographic information system (GIS). I used principal components analysis to find four variables representing most regional climate variation: average annual precipitation, the difference between December and July precipitation, average annual...
The gas phase electron-diffraction (GED) technique has been the primary method used to expand our knowledge and understanding of gas-phase molecular structures. The technique yields interatomic distances and bond angles that are of use in both theoretical and experimental studies.
The GED structural parameters are thermal averages over all vibrational...
A fundamental relationship of inherent optical properties (IOP) is that the
beam attenuation coefficient is the sum of the volume absorption and scattering
coefficients (c = a + b). A relative calibration of a set of instruments can be provided
using this IOP closure equation. Measurement of the true beam...
Spawning salmon create patches of disturbance through redd digging which can reduce macroinvertebrate abundance and biomass in spawning habitat. We asked whether displaced invertebrates use non-spawning habitats as refugia in streams. Our study explored how the spatial and temporal distribution of macroinvertebrates changed during a pink salmon (Oncorhynchus gorbuscha) spawning...
