Background: Short RNAs, and in particular microRNAs, are important regulators of gene
expression both within defined regulatory pathways and at the epigenetic scale. We investigated
the short RNA (sRNA) population (18-24 nt) of the transcriptome of green leaves from the
sequenced Populus trichocarpa using a concatenation strategy in combination with...
Since 1958 when Alfred C. Redfield (1) recognized the similarity between the ratios of elements in living biomass and those dissolved in the surrounding seawater, we have understood that microorganisms largely control the concentrations, distribution, and molecular makeup of nutritional resources in the ocean. The primary elemental ingredients for life,...
Recent natural disasters around the world including
both tsunamis and hurricanes, have highlighted the inability
of wood buildings to withstand wave and surge
loading during these extreme events. Little is known
about the interaction between coastal residential light-frame
wood buildings and wave and surge loading because
often little is left...
This study quantifies the short-term effects of low-, moderate-, and high-severity fire on carbon pools and fluxes in the Eastern Cascades of Oregon. We surveyed 64 forest stands across four fires that burned 41,000 ha (35%) of the Metolius Watershed in 2002 and 2003, stratifying the landscape by burn severity...
Pretreatment of male C57BL/6 mice with low doses of the persistent organochlorine
(OC) pesticide, chlordecone (CD), stimulated biliary excretion of exogenous CH up to 3-fold. Increased biliary excretion occurred without changes in hepatic ATP-binding
cassette transporter G8 (ABCG8) of the bile canaliculus or scavenger receptor class B
type I (SR-BI)...
Tsunami force and pressure distributions on a rigid
wall fronted by a small seawall were determined experimentally
in a large-scale wave flume. Six different
seawall heights were examined, two of which were exposed
to a range of solitary wave heights. The same
experiment was done without a seawall for comparison....
A definition is suggested for affine symmetry tensors, which generalize the notion of affine vectors in the same way that (conformal) Killing tensors generalize (conformal) Killing vectors. An identity for these tensors is proven, which gives the second derivative of the tensor in terms of the curvature tensor, generalizing a...
The eastern South Pacific (ESP) oxygen minimum zone (OMZ) is a permanent hydrographic feature located directly off the coasts of northern Chile and Peru. The ESP OMZ reaches from coastal waters out to thousands of kilometers offshore, and can extend from the near surface to depths greater than 700 m....
The Gene Ontology (GO) Consortium (http://www.geneontology.org) (GOC) continues to develop,
maintain and use a set of structured, controlled
vocabularies for the annotation of genes, gene
products and sequences. The GO ontologies
are expanding both in content and in structure.
Several new relationship types have been introduced
and used, along with...
Recent work by S. Lentz et al. documents offshore transport in the inner shelf due to a wave-driven return
flow associated with the Hasselmann wave stress (the Stokes–Coriolis force). This analysis is extended using
observations from the central Oregon coast to identify the wave-driven return flow present and quantify the...
