Low temperature atomic layer deposition (ALD) of monolayer to few layer MoS₂ uniformly across 150mm diameter SiO₂/Si and quartz substrates is demonstrated. Purge separated cycles of MoCl5 and H₂S precursors are used at reactor temperatures of up to 475 °C. Raman scattering studies show clearly the in-plane (E¹₂g) and out-of-plane...
The genome of the multicapsid nuclear polyhedrosis virus of
Orgyia pseudotsugata (OpMNPV) was mapped by examining overlapping
Hindlll fragments from cosmid clones which had been constructed
from partial Hindlll digests of viral DNA. Five OpMNPV cosmid
clones containing fragments encompassing the entire OpMNPV genome
were hybridized to blots of DNA...
Stacked sheets of polyethylene terephthalate andpolystyrene provide a means
for recovering projectiles travelling at hypervelocities. The transparency of these
multiple diaphragms is utilized so that light generated from hypervelocity impacts
can be studied.
A method for gathering visible as well as ultraviolet light from less
transparent polymer foams has been...
The standard way of representing numbers on computers gives rise to errors
which increase as computations progress. Using p-adic valuations can reduce
error accumulation. Valuation theory tells us that p-adic and standard valuations
cannot be directly compared. The p-adic valuation can, however, be used in
an indirect way. This gives...
Financial stress in agriculture has been a concern over the past
century. Agrarian values and "love of the land" seem to yield public
conclusions for the support of the industry. Much of this support is
in the interest of preserving a viable food producing sector in an
volatile world climate....
This paper examines the probability that a random polynomial of specific degree over a field has a specific number of distinct roots in that field. Probabilities are found for random quadratic polynomials with respect to various probability measures on the real numbers and p-adic numbers. In the process, some properties...

We examined 120 vexillifer larvae of Echiodon dawsoni and 40 of Carapus bermudensis collected from the continental shelf and slope of the Gulf of Mexico and the western North Atlantic to Nova Scotia. Age was estimated for a subset of vexillifers, from which otoliths (sagittae) were excised and growth increments...
Droplet dynamics analysis concerns the measurements of droplet volume, cap and base areas and
contact angles, as they change in time to study evaporation, wettability, adhesion and other
surface phenomena and properties. In a typical procedure, the two-dimensional measurements
are based on a series of images recorded at successive stages...
During August 1986, a large cold anomaly was observed in satellite and in situ measurements near Cape Blanco at 42°N, 126°30′W off the Pacific Coast. Detailed vertical profiles of temperature, conductivity, turbulent dissipation, and horizontal currents showed 1) surface water temperature changes as large as 2 degrees in 1 kilometer...
A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...
We describe the migration distances and timing of the adult Pacific lamprey, Entosphenus tridentatus, in the Willamette River Basin (Oregon, U.S.A.). We conducted aerial surveys to track radio-tagged fish upstream of a major waterfall and hydropower complex en route to spawning areas. We detected 24 out of the 43 fish...
Hot electron luminescence experiments are performed on ZnS alternating-current thin-film electroluminescent (ACTFEL) devices in order to determine the extent to which the electron distribution is heated. The luminescence spectrum is found to be broad and essentially featureless up to a high energy cutoff of approximately 3.7 eV, which is determined...
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...
Regression models of height growth and survival were fitted to aggregate data for trees, protected and not protected from animal damage, that had been surveyed on Douglas-fir and ponderosa pine plantations in Oregon and Washington. Animal damage significantly affected both height and survival. Dynamic programming analysis-using both soil expectation (Se)...
Photosynthetic diatoms and marine bacteria contribute about one third of the net primary production in marine environments. Understanding the interactions between these two organisms is potentially important to the over all flow of carbon in the marine ecosystem.
Loss of native vegetation cover is thought to be a major driver of declines in pollination success worldwide. However, it is not well known whether reducing the fragmentation of remaining vegetation can ameliorate these negative effects. We tested the independent effects of composition vs. configuration on the reproductive success of...
We investigated the movements and selection of settlement sites of translocated pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged, and translocated 59 pygmy rabbits across big sagebrush (Artemisia tridentata ssp.) habitat with 3 categories of landscape fragmentation. We used radio telemetry to...
Although the regulations are imperfectly enforced, logging firms in the Brazilian Amazon are subject to
forest management regulations intended to reduce environmental damage and protect future forest productivity.
Additionally, voluntary best practices firms adopt to achieve environmental performance that
exceed regulatory requirements are largely limited to reduced impact logging (RIL)...
A fast-response chromel–constantan thermocouple sensor was constructed for use on the microstructure profiler Chameleon and used for 60 ocean profiles off the coast of Oregon. The stability of the thermocouple was compared to that of an FP07 microbead thermistor, and its frequency response was compared to a high-resolution microconductivity probe....
Tests of a formula derived for the cutoff wave number of vertical temperature gradient spectra, using
data taken in the upper layers of the North Pacific, show encouraging results. To derive this formula, the
cutoff wave number is assumed to be the Batchelor wave number, with kinetic energy dissipation calculated...
We demonstrate color shifting from the yellow to the red in the electroluminescence from (ZnGa)S:Mn films. We observe threshold voltages down to about 35 V, extremely low for such devices. We discuss the materials characteristics of the phosphor films, and the potential for improvement of the luminous intensity of the...
High electron mobility thin films of In₂₋ₓWₓO₃₊y(0≤x≤0.075) were prepared on amorphous SiO₂ and single-crystal yttria-stablized zirconia (001) substrates by pulsed laser deposition. Mobilities ranged between 66 and 112 cm² /Vs depending on the substrate type and deposition conditions, and the highest mobility was observed at a W-dopant concentration of x~0.03....
A unique approach for obtaining bright and efficient saturated green phosphors for alternating-current thin-film electroluminescent (ACTFEL) device applications is presented. The approach involves color-shifting blue SrS:Cu,F ACTFEL phosphors into the green region of the spectrum via the incorporation of alkali metal ions into the SrS lattice. Alkali metals are incorporated...
