BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
This report is the eighth in a series that describe recent oceanographic observations within the California Current system, from Oregon to Baja California. The emphasis here is placed on the observations conducted concurrently by the CalCOFI (California Cooperative Oceanic Fisheries Investigations), IMECOCAL (Investigaciones Mexicanas de la COrriente de CALifornia), and...
Penetration of ¹⁴C-labeled plant growth regulators into the surface of apple
(Malus pumila M.) leaves pre-soaked in 10 ml I⁻¹ solutions of surfactant was
measured by detecting changes in radioactivity of the solution in glass cylinders
sealed to the astomatal, adaxial surface of the leaf discs. Penetration of 2,4-D
[(2,4-dichlorophenoxy)acetic...
The Laplace-Beltrami operator of a smooth Riemannian manifold is determined by the Riemannian metric. Conversely, the heat kernel constructed from the eigenvalues and eigenfunctions of the Laplace-Beltrami operator determines the Riemannian metric. This work proves the analogy on Euclidean polyhedral surfaces (triangle meshes), that the discrete heat kernel and the...
We inferred the population densities of blue whales (Balaenoptera musculus) and short-beaked
common dolphins (Delphinus delphis) in the Northeast Pacific Ocean as functions
of the water-column’s physical structure by implementing hierarchical models in a Bayesian
framework. This approach allowed us to propagate the uncertainty of the field observations
into the...
Rivers display temporal dependence in suspended sediment–water discharge relationships. Although most work has focused on multi-decadal trends, river sediment behavior often displays sub-decadal scale fluctuations that have received little attention. The objectives of this study were to identify inter-annual to decadal scale fluctuations in the suspended sediment–discharge relationship of a...
This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...
This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...
Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...
Molecular tools, coupled with unique germplasm stocks and rigorous phenotyping, are
useful for developing a better understanding of qualitative and quantitative disease resistance
genes in plants. The identification of molecular markers linked to all types of resistance
genes provides opportunities for implementing a range of resistance breeding strategies,
ranging from...
