A new functional gene database, FOAM (Functional
Ontology Assignments for Metagenomes), was developed
to screen environmental metagenomic sequence
datasets. FOAM provides a new functional
ontology dedicated to classify gene functions relevant
to environmental microorganisms based on Hidden
Markov Models (HMMs). Sets of aligned protein
sequences (i.e. ‘profiles’) were tailored to...

We propose generalized additive partial linear models for complex data
which allow one to capture nonlinear patterns of some covariates, in the presence
of linear components. The proposed method improves estimation efficiency
and increases statistical power for correlated data through incorporating
the correlation information. A unique feature of the proposed...

Bioelution assays are fast, simple alternatives to in vivo testing. In this study, the intra- and inter-laboratory variability in bioaccessibility data generated by bioelution tests were evaluated in synthetic fluids relevant to oral, inhalation, and dermal exposure. Using one defined protocol, five laboratories measured metal release from cobalt oxide, cobalt...
This research examines the community composition of biotic soil crusts at nine
sites in central and eastern Oregon, U.S.A. At each site, data were collected in one pair
of livestock-grazed and excluded transects. Variables recorded included: cover of biotic
soil crusts and vascular plant species, soil surface pH, electrical conductivity,...

Software developers frequently need to perform code maintenance tasks, but doing so requires time-consuming navigation through code. A variety of tools are aimed at easing this navigation by using models to predict places in the code that a developer might want to visit, and then providing shortcuts so that the...
Slickspots are soil inclusions with unique loamy soils that provide habitats for many endemic plants worldwide, including those within sagebrush steppe. Sagebrush-dominated communities are declining and require restoration, but restoration techniques commonly used may impact negatively some intermixed communities found on soil inclusions including those on slickspot soils. Slickspot soils...

A study of precipitation and yield levels in fallow-wheat rotations at three
Pacific Northwest locations demonstrated that in the Columbia Plateau region,
the variability and skewness of precipitation increased with decreasing mean
amounts of precipitation. The seasonal distribution of precipitation had a
marked effect on wheat yield. Comparisons of precipitation...
