Helium isotopes are a robust geochemical tracer of a primordial mantle component in hot spot volcanism. The high ³He/⁴He (up to 35 RA, where RA is the atmospheric ³He/⁴He ratio of 1.39 X 10¯⁶) of some Hawaiian Island volcanism is perhaps the classic example. New results for picrites and basalts...
The primary Mg/Ca ratio of foraminiferal shells is a potentially valuable paleoproxy for sea surface
temperature (SST) reconstructions. However, the reliable extraction of this ratio from sedimentary calcite
assumes that we can overcome artifacts related to foraminiferal ecology and partial dissolution, as well as
contamination by secondary calcite and clay....
Transparent thin-film transistors (TTFTs) with an amorphous zinc tin oxide channel layer formed via rf magnetron sputter deposition are demonstrated. Field-effect mobilities of 5–15 and 20–50 cm² V‾¹ s‾¹ are obtained for devices post-deposition annealed at 300 and 600 °C, respectively. TTFTs processed at 300 and 600 °C yield devices...
A huge discrepancy between theory and practice exists in one popular application area of functional programming--spreadsheets. Although spreadsheets are the most frequently used (functional) programs, few formal models of computation and type systems exist that would provide the foundation for creating reliable spreadsheets. Consequently, existing spreadsheets contain many errors, some...

90% in a coarse-grained turbidite sequence beneath the gas
hydrate stability zone (GHSZ) at south Hydrate Ridge, in the
Cascadia accretionary complex. The geometry of this gas-saturated
bed is defined by a strong, negative-polarity
reflection in 3D seismic data. Because...
Many Oregon communities face serious and growing risks from wildfires. These fires are increasingly large and severe after many decades of fire suppression and land use changes, flammable fuel buildups and interactions with climate. The wildland-urban interface (WUI) continues to expand as people relocate to rural areas where they often...
As part of the 2004 Oregon Fire Program Review, the Oregon Department of Forestry (ODF) formed the Forest Fuels and Hazard Mitigation (FFHM) Committee to assess hazardous fuel loading issues, and recommend ways to reduce risk, and improve and strengthen the multiple hazard mitigation strategies in Oregon.
A statewide wildfire...
Abrupt transitions to strongly superrotating states have been found in some idealized models of the troposphere. These transitions are thought to be caused by feedbacks between the eddy momentum flux convergence in low latitudes and the strength of the equatorial flow. The behavior of an axisymmetric shallow-water model with an...
Climate can affect population dynamics in indirect ways via nonadditive forcing by external variables on internal demographic rates. Current analytical techniques, employed in population ecology, fail to explicitly include nonadditive interactions between internal and external variables, and therefore cannot efficiently address indirect climate effects. Here, we present the results of...
We developed a tool that migrates the database schema and the data from one database to another. As DBMSs store the same data by using slightly different data types, one cannot simply copy all the tables and data from the source DBMS to the target DBMS. When our tool, db2db,...
