Measurements on growth traits up to 41 years of age
from 68 progeny sites in eight first-generation breeding
zones of coastal Douglas-fir (Pseudotsuga menziesii
[MIRB.] FRANCO var. menziesii) in the US Pacific Northwest
were used to investigate age trends of genetic parameters
and to determine optimum age of selection. Heritabilities...
Eliciting information from experts for use in constructing prior distributions for logistic regression coefficients can be challenging. The task is especially difficult when the model contains many predictor variables, because the expert is asked to provide summary information about the probability of “success” for many subgroups of the population. Often,...
Importance sampling algorithms are discussed in detail, with an emphasis on implicit sampling, and applied to data assimilation via particle filters. Implicit sampling makes it possible to use the data to find high-probability samples at relatively low cost, making the assimilation more efficient. A new analysis of the feasibility of...
OBJECTIVE: To investigate whether an increase in daily tooth brushing frequency in children was predicted by either a) having a strong intention to brush twice a day or b) their parents receiving information about their new caries experience.
BASIC RESEARCH DESIGN: Secondary data analyses were conducted on two waves of...
To guide the future development of CO₂-atmospheric inversion modeling systems, we analyzed the errors arising from prior information about terrestrial ecosystem fluxes. We compared the surface fluxes calculated by a process-based terrestrial ecosystem model with daily averages of CO₂ flux measurements at 156 sites across the world in the FLUXNET...
OBJECTIVE. To quantify the association between admission to an intensive care unit (ICU) room most recently occupied by a patient positive for extended-spectrum beta-lactamase (EBSL)-producing gram-negative bacteria and acquisition of infection or colonization with that pathogen.
DESIGN. Retrospective cohort study.
SETTING AND PATIENTS. The study included patients admitted to medical...
With advancing computational resources, 3-D inversion techniques have become feasible in recent years and are now a more widely used tool for magnetotelluric (MT) data interpretation. Galvanic distortion caused by small-scale near-surface inhomogeneities remains an obstacle for 3-D MT inversion which so far has experienced little attention. If not considered...
The vitamin D receptor (VDR) mediates the pleiotropic biologic effects of 1alpha,25
dihydroxy-vitamin D3. Recent in vitro studies suggested that curcumin and poly-unsaturated fatty
acids (PUFAs) also bind to VDR with low affinity. As potential ligands for the VDR, we hypothesized
that curcumin and PUFAs would induce expression of known...
The subduction of the oceanic spreading center at the Chile Triple Junction is marked by a substantial thermal perturbation
and marked changes in the hydrogeologic and aqueous geochemical regimes in the overthrust plate. Ridge subduction substantially
changes the fluid chemistry in the wedge through variably hydrating the oceanic basement, accretionary...
A new enhanced swing class-D VCO which operates from a supply voltage as low as 300 mV is presented. The architectural advantages are described along with an analysis for the oscillation frequency. Prototype differential and quadrature variants of the proposed VCO have been implemented in a 65 nm RF CMOS...
This work sought to determine high pressure processing (HPP) effects on the activity of cathepsins B and D in the muscle of mackerel (Scomber scombrus) and horse mackerel (Trachurus trachurus). In mackerel, the cathepsin B activity decrease reached 40% at 450 MPa while in horse mackerel, low and intermediate pressures...
Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...
Long period (10–20,000 s) magnetotelluric (MT) data are being acquired across the continental USA on a quasi-regular grid of ∼70 km spacing as an electromagnetic component of the National Science Foundation EarthScope/USArray Program. These data are sensitive to fluids, melts, and other organic indicators, and thus provide a valuable complement...
Physical mapping and genome sequencing are underway for the ≈17 Gb wheat genome. Physical mapping methods independent of meiotic recombination, such as radiation hybrid (RH) mapping, will aid precise anchoring of BAC contigs in the large regions of suppressed recombination in Triticeae genomes. Reports of endosperm development following pollination with...
Two-photon, planar laser-induced fluorescence (PLIF) of carbon-monoxide (CO) and two-dimensional thermometry employing two-color, hydroxyl radical (OH) PLIF are used to characterize atmospheric-pressure inverse diffusion flames. These flames are important tools to aid the understanding of secondary reaction zones that may form in gas turbine engines when film-cooling air reacts with...
Male Apis mellifera L. (drones) accompanying reproductive swarms were analyzed for honey stomach contents to determine if they engorge honey prior to or during swarming. No evidence for engorgement was found. A diurnal feeding rhythm in drones was observed in non swarming colonies.
The growth of secondary vortices on the braids separating Kelvin–Helmholtz billows is investigated via numerical simulations. The similarity theory of Corcos & Sherman (1976) is extended to include mixing processes with Prandtl number greater than unity, and is shown to provide a useful description of the physics of the braid...
This study uses 9 years of longitudinal, student-level data from the Los Angeles Unified School District to provide updated, empirically–based estimates of the time necessary for English learners (ELs) to become reclassified as proficient in English, as well as factors associated with variation in time to reclassification. To illustrate how...
This paper supersedes and significantly revises my compilation of 1992. The focus remains on live birds seen on or from land, but special codes are now given for records of species only reported beached or at sea.
Additionally, confirmation codes are now listed for records of some rare species and...
It has generally been assumed by historians and anthropologists that the indigenous groups living to the west and northwest of the Colorado River were non-horticultural with three or four exceptions: some horticulture among the eastern-most Kamia, among the Chemehuevi who settled at a late date along the Colorado River, and...
