A recent identification of the two-component aggregation pheromone of the invasive stink bug species, Halyomorpha halys (Stal), in association with a synergist, has greatly improved the ability to accurately monitor the seasonal abundance and distribution of this destructive pest. We evaluated the attraction of H. halys to black pyramid traps...
Transparent films of CuScO₂₊ₓ have been prepared which show p-type electrical conductivity. The temperature dependence of the conductivity indicates semiconducting behavior with an apparent room temperature activation energy of 0.11 eV. The highest room temperature conductivity observed was 30 S cm⁻1. Films 110 nm thick show 40% transparency in most...
This study shows how patronage framed and fashioned the careers of Thomas Hobbes and
his patron William Cavendish, the earl of Newcastle. Newcastle's protection allowed
Hobbes to articulate heterodox ideas without immediate fear of reprisal. It also enabled
him to solidify his status as a gentleman and the intellectual equal...
CuCr₁₋ₓMgₓO₂, a wide band gap semiconductor with the delafossite structure, has been synthesized
in bulk and thin-film form. Bulk undoped CuCrO₂ is almost black and has moderate conductivity
with p-type carriers. Upon doping with 5% Mg, the conductivity increases by a factor of 1000. In
films, the best p-type conductivity...
Thomas and Megahan [1998] provide a thoughtful reanalysis of our earlier paper [Jones and Grant, 1996]. Thomas and Megahan [1998] (hereinafter referred to as T&M) reacted to three assertions made by Jones and Grant [1996] (hereinafter referred to as J&G): (1) "forest harvesting has increased peak discharges by as much...
Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...
Real-time PCR assays using locked nucleic acid (LNA) probes and high resolution melt (HRM) analysis were developed for molecular differentiation of Pseudoperonospora cubensis and P. humuli, causal agents of cucurbit and hop downy mildew, respectively. The assays were based on a previously identified single nucleotide polymorphism (SNP) in the cytochrome...
Previously published physical and biological data document a zonally oriented frontal region within the California Current system separating colder and more eutrophic water north of ≈33°N from warmer; more stratified, and oligotrophic water farther to the south. Satellite images of phytoplankton pigment from the coastal zone color scanner from 1979-1983...
A 5-year time series of coastal zone color scanner imagery (1980-1983, 1986) is used to examine
changes in the large-scale pattern of chlorophyll pigment concentration coincident with the spring
transition in winds and currents along the west coast of North America. The data show strong
interannual variability in the timing...
A numerical model has been used to investigate the wind-driven circulation in a stratified basin of
moderate size, Lake Tahoe, California-Nevada. Two types of circulation are identified: "direct" circulations,
in which the current directions remain relatively constant and the mean circulation formed over
several days resembles the instantaneous circulation, and...
