Let X and Y be a pair of smooth manifolds, each obtainable
from the other by surgery in codimension at least three. We show that the
corresponding spaces Riem⁺(X) and Riem⁺(Y), respectively consisting of
Riemannian metrics of positive scalar curvature on X and Y, are homotopy
equivalent. This result is...
A historical record of Pacific Northwest (defined here as west of the Cascade Mountains in Washington and Oregon) heat waves is identified using the U.S. Historical Climate Network, version 2, daily data (1901–2009). Both daytime and nighttime events are examined, defining a heat wave as three consecutive days above the...
A retrospective study of brain lesions in goats was conducted to identify the range of lesions and diseases recognized and to make recommendations regarding the best tissues to examine and tests to conduct in order to maximize the likelihood of making a definitive diagnosis in goats that may have had...
The University of Oregon Libraries and Oregon State University Libraries have been successfully collaborating on a digital asset management system for four years, OregonDigital.org. OregonDigital.org holds diverse collections of digital archival materials from art slides to faculty research to traditional digitized and born-digital archival collections. In addition, we host unique...
Stream temperatures were monitored on seven low-elevation western Oregon streams immediately after clearcut harvesting and 14-17 years later in two studies that examined buffer designs. One study on four streams used no-tree buffers with all trees next to the stream harvested within the clearcut units. The second study on three...
Using spatial autocorrelation analysis, we
examined the within-population genetic structure of
Rhizopogon vinicolor and R. vesiculosus, two hypogeous
ectomycorrhizal (EM) species that are sympatric
sister taxa known to differ in their clonal structure.
We collected 121 sporocarps and 482 tuberculate EM
of both species from a 20 ha forest stand...
Obesity contributes to increased risk for several chronic diseases including cardiovascular disease and type 2 diabetes. Xanthohumol, a prenylated flavonoid from hops (Humulus lupulus), was tested for efficacy on biomarkers of metabolic syndrome in 4 week old Zucker fa/fa rats, a rodent model of obesity. Rats received daily oral doses...
The purpose of this study was to examine three frameworks, (a) process-product,
(b) student mediation, and (c) classroom ecology, to understand physical activity
(PA) behavior of adolescents with and without disabilities in middle school
inclusive physical education (PE). A total of 13 physical educators teaching inclusive
PE and their 503...
