Type-II dilemma zones are the segment of roadway approaching an intersection where drivers have difficulty deciding to stop or proceed at the onset of the circular yellow (CY) indication. Signalized intersection safety is improved when dilemma zones are correctly identified and steps are taken to reduce the likelihood that vehicles...
Many bacteria possess cell density-dependent quorum-sensing (QS) systems that often regulate cooperative secretions involved
in host-microbe or microbe-microbe interactions. These secretions, or “public goods,” are frequently coregulated by stress and
starvation responses. Here we provide a physiological rationale for such regulatory complexity in the opportunistic pathogen
Pseudomonas aeruginosa. Using minimal-medium...
Microglia and reactive astrocytes accumulate in the spinal cord of rats expressing the Amyotrophic lateral sclerosis (ALS)-linked SOD1ᴳ⁹³ᴬ mutation. We previously reported that the rapid progression of paralysis in ALS rats is associated with the appearance of prolifer- ative astrocyte-like cells that surround motor neurons. These cells, designated as Aberrant...
BACKGROUND: The wild grass Brachypodium distachyon has emerged as a model system for temperate grasses and
biofuel plants. However, the global analysis of miRNAs, molecules known to be key for eukaryotic gene regulation,
has been limited in B. distachyon to studies examining a few samples or that rely on computational...

A high-rate synthesis of Cu-BTC metal-organic frameworks with BET surface area of more than 1600 m²/g (Langmuir surface area of more than 2000...
Molecular dynamics (MD) simulations are used to study, in detail, the transfer of thermal (vibrational) energy between objects with discrete vibrational spectra to those with a semi-continuum of spectra. The transfer of energy is stochastic and strongly dependent on the instantaneous separation between the bodies. The insight from the MD...
The Ti plasmid in Agrobacterium tumefaciens strain 15955 carries two alleles of traR that regulate conjugative transfer. The first
is a functional allele, called traR, that is transcriptionally induced by the opine octopine. The second, trlR, is a nonfunctional,
dominant-negative mutant located in an operon that is inducible by the...
The role of each habitat fish use is of great importance to the dynamics of populations. During
their early marine residence, Chinook salmon (Oncorhynchus tshawytscha), an anadromous fish
species, mostly inhabit estuaries but also use sandy beach surf zones and the coastal ocean.
However, the role of surf zones in...
The Mongolian Steppe is one of the largest remaining grassland ecosystems. Recent studies have reported widespread
decline of vegetation across the steppe and about 70% of this ecosystem is now considered degraded. Among
the scientific community there has been an active debate about whether the observed degradation is related to...
The exponential growth of the salmonid farming industry during the last 3 decades has created conditions for massive escapes of these exotic species into natural environments in southern Chile. Here, we review and update information about salmonid escapes from 1993 to 2012 and examine their potential environmental, social, and economic...
Background: Nonalcoholic steatohepatitis (NASH) is a progressive form of nonalcoholic fatty liver disease and a risk
factor for cirrhosis, hepatocellular carcinoma and liver failure. Previously, we reported that dietary docosahexaenoic
acid (DHA, 22:6,n-3) was more effective than eicosapentaenoic acid (EPA, 20:5,n-3) at reversing western diet (WD)
induced NASH in LDLR-/-...
Research progress to understand the role of vitamin C (ascorbic acid) in human health has been slow in coming.

Deep cycle mixing in the cold tongue of the equatorial
Pacific Ocean is associated with a mean flow regime
in which the gradient Richardson number Ri (a ratio of
stratification to shear that affects the evolution of turbulence)
fluctuates about a critical value near 1/4. This is the state
of...
The frictional resistance on a fault during slip controls earthquake dynamics. Friction dissipates heat during an earthquake; therefore the fault temperature after an earthquake provides insight into the level of friction. The JFAST project (IODP Expedition 343/343T) installed a borehole temperature observatory 16 months after the March 2011 M[subscript w]9.0...
Dietary selenium (Se) alters whole-blood Se concentrations in sheep, dependent upon Se source and dosage administered, but little is known about effects on immune function. We used footrot (FR) as a disease model to test the effects of supranutritional Se supplementation on immune function. To determine the effect of Se-source...
The amino acid acridon-2-ylalanine (Acd) can be a valuable probe of protein conformational change because it is a
long lifetime, visible wavelength fluorophore that is small enough to be incorporated during ribosomal biosynthesis. Incorporation
of Acd into proteins expressed in E. coli requires efficient chemical synthesis to produce large quantities...
The manuscript reports on simulations of the intrinsic dissipation of standing and traveling
flexural vibrations in carbon nanotubes. It is found that extended traveling and standing waves
exhibit anomalous dissipation, during which the excited modes experience massive damping
that is triggered by the accumulation of energy in special gateway modes....
We quantified the relative influence of maternal fidelity to feeding grounds and natal
fidelity to breeding grounds on the population structure of humpback whales Megaptera novae-angliae based on an ocean-wide survey of mitochondrial (mt) DNA diversity in the North Pacific.
For 2193 biopsy samples collected from whales in 10 feeding...
The Bering Sea ecosystem has experienced significant climatic and biological shifts
over the past 3 decades, including temporal and spatial fluctuations of jellyfish biomass. Jellyfish

factors on their population dynamics. We explored the...
We have compared the helium isotope ratio in five
samples of Pacific marine air spanning the 40 year period
between 1973 and 2013 against a secondary gas standard. In
a separate experiment we directly compared the ³He/⁴He
ratio in air samples collected in 1973 and 2013 at the same
location...
BACKGROUND: Meniscal injury is a common cause of lameness in the dog. Tissue engineered bioscaffolds may be a treatment option for meniscal incompetency, and ideally would possess meniscus-like extracellular matrix (ECM) and withstand meniscal tensile hoop strains. Synovium may be a useful cell source for meniscal tissue engineering because of...
Nonlinear mesoscale eddies can influence biogeochemical cycles in the upper ocean through vertical and horizontal advection of nutrients and marine organisms. The relative importance of these two processes depends on the polarity of an eddy (cyclones versus anticyclones) and the initial biological conditions of the fluid trapped in the core...
Idealized numerical simulations utilizing the Regional Ocean Modeling System (ROMS) are carried out to examine the response of buoyant river plume systems to offshore-directed wind stresses. It is found that after a few inertial periods of wind forcing the plume becomes detached from the coast and reaches a steady state...

As mobile technologies continue to evolve, libraries seek sustainable ways to keep up with these changes and to best serve our users. Previous library mobile usability research has examined tasks users predict they might be likely to perform, but little is known about what users actually do on a mobile-optimized...
Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus...
An experimentally based, quantitative understanding of the entrapment and function of small peptides within PEO brush layers does not currently exist. Earlier work provided a rationale for expecting that an ordered, compact peptide will enter the PEO phase more readily than a peptide of similar size that adopts a less...
Remediation methods and strength predictions were evaluated for wood I-joists with single, circular holes in the webs, leaving utilities in place. A full-scale bending test using four equally-spaced point loads was applied to three depths of joists with varying flange widths and span lengths of 4.88 m and 2.44 m....

The recent economic downturn severely affected the US forest sector from a macro-economic perspective but little is known about changes in firm-level performance. In this study we investigate the changes in financial, social and environmental performance of forest sector firms during a period approximately corresponding to the downturn. We also...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
Large shifts in species ranges have been predicted under future climate scenarios based primarily on niche-based species distribution models. However, the mechanisms that would cause such shifts are uncertain. Natural and anthropogenic fires have shaped the distributions of many plant species, but their effects have seldom been included in future...
Candidatus Liberibacter solanacearum’ (Lso) is a bacterium that infects solanaceous crops and causes plant decline and yield losses, especially in potato and tomato. Lso is transmitted to these hosts by the potato psyllid (Bactericera cockerelli Sulc) vector. B. cockerelli host plants are not limited to crop plants, but also include...

High-quality data collected on system components...
High nitrogen (N) accumulation in terrestrial ecosystems can shift patterns of nutrient limitation and deficiency beyond N toward other nutrients, most notably phosphorus (P) and base cations (calcium [Ca], magnesium [Mg], and potassium [K]). We examined how naturally high N accumulation from a legacy of symbiotic N fixation shaped P...
This work focuses on the effect of a previous high pressure processing (HPP) on the lipid damage development occurring during the frozen storage (-10ºC; up to 3 months) of Atlantic horse mackerel (Trachurus trachurus). HPP conditions included different pressure (150, 300, 450 MPa) and pressure holding time (0.0, 2.5, 5.0...
Wireless LANs (WLANs) have been widely adopted and are more convenient as they are inter-connected as wireless campus networks and wireless mesh networks. However, time-sensitive multimedia applications, which
have become more popular, could suffer from long end-to-end latency in WLANs.
This is due mainly to handoff delay, which in turn...
We analyze the convergence to equilibrium of solutions to the nonlinear Berger plate evolution
equation in the presence of localized interior damping (also referred to as geometrically constrained
damping). Utilizing the results in [24], we have that any trajectory converges to the set of stationary
points N. Employing standard assumptions...
The flux of water vapor due to advection is measured using high-resolution Raman lidar that was orientated
horizontally across a land–lake transition. At the same time, a full surface energy balance is performed to assess
the impact of scalar advection on energy budget closure. The flux of water vapor due...
Introduced vector-borne diseases, particularly avian malaria (Plasmodium relictum) and avian pox
virus (Avipoxvirus spp.), continue to play significant roles in the decline and extinction of native forest birds in
the Hawaiian Islands. Hawaiian honeycreepers are particularly susceptible to avian malaria and have survived
into this century largely because of persistence...
In this paper we extend the results of the research started by the first author in which Karlin-McGregor diagonalization of certain reversible Markov chains over countably infinite general state spaces by orthogonal polynomials was used to estimate the rate of convergence to a stationary distribution. We use a method of...
Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses. To enable basic and applied research of this important pest, we sequenced the D. suzukii genome...
Reproductive strategies of birds are shaped by patterns of food supply, yet empirical evidence of the consequences and mechanisms of food limitation on reproductive performance is inconsistent, probably due to variable responses from species of differing life-history strategies. We tested the hypothesis that food supplementation would increase reproductive rates of...
In response to a question raised by Knox Lovell, we develop a method for estimating directional output distance functions with endogenously determined direction vectors based on exogenous normalization constraints. This is reminiscent of the Russell measure proposed by Färe and Lovell (J Econ Theory 19:150–162, 1978). Moreover it is related...
Abnormal physiological responses of plant cultures such as shoot tip necrosis, callus, and hyperhydricity are some of the most difficult challenges in shoot micropropagation, and their causes are not well understood. Five Murashige and Skoog mineral salt factors, which influence the growth of pear shoot cultures, were tested in a...
Forest harvest residues can be a cost-effective feedstock for a biorefinery, but the high
lignin content of forest residues is a major barrier for enzymatic sugar production. Sulfite
pretreatment to overcome strong recalcitrance of lignocelluloses (SPORL) was applied to a
Douglas-fir (Pseudotsuga menziesii (Mirb) Franco var. menziesii) forest residue in...
Various simple mathematical models have been used to investigate dengue transmission. Some of these models explicitly model the mosquito population, while others model the mosquitoes implicitly in the transmission term. We study the impact of modeling assumptions on the dynamics of dengue in Thailand by fitting dengue hemorrhagic fever (DHF)...
We investigated the species identity and local use of cetaceans on the Gilbert
Islands, Republic of Kiribati. Working with the Kiribati Ministry of Environment,
Lands and Agricultural Development and Fisheries Division, we visited
the islands of Tarawa, Tabiteuea (North), Butaritari and Onotoa from June to
July 2009, and collected 24...
From the planning days preceding the establishment of the US Global
Ocean Ecosystem Dynamics (GLOBEC) program, modeling was recognized as one
of the program’s pillars. In particular, predictions of future ecosystem states in an
evolving climate system required new interdisciplinary approaches that brought
together physicists, biologists, modelers, and observational scientists....
Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. We examined how site environment and initial substrate quality influence decomposition and nitrogen (N) dynamics of multiple litter types. A 2.5-year decomposition study was installed in the Oregon Coast Range and West Cascades using ¹⁵N-labeled litter from Acer macrophyllum,...
Background: There is evidence that seasonal variation in depressive symptoms is common in the population. However, research is limited by a reliance on longterm retrospective methods. Methods: Seasonal patterns were tested in two samples of community participants recruited in separate prospective studies in the Midwestern (n = 556 males/females) and...
Advocates for language minority students depict the movement for language minority students' rights as an outgrowth of the civil rights movement, which focused initially on securing rights for racial minorities. This article examines whether the same conceptions of equality and legal remedies apply for both groups. Building on Berlin's notions...
A primary focus of the US Global Ocean Ecosystem Dynamics
(GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale
climate forcing under the assumption that bottom-up forcing controls a large
fraction of marine ecosystem variability. At the beginning of GLOBEC, the prevailing
bottom-up forcing hypothesis was that...
The Autographa californica M nucleopolyhedrovirus (AcMNPV) sulfhydryl oxidase Ac92 is essential for production of infectious virions. Ac92 also interacts with human p53 and enhances human p53-induced apoptosis in insect cells, but it is not known whether any relationship exists between Ac92 and native p53 homologs from insect hosts of AcMNPV....
Heterodera avenae and H. filipjevi are economically important cyst nematodes that restrict production of cereal crops in the Pacific Northwest United States and elsewhere in the world.

The purpose of this study was to gain information about the characteristics of small restaurant owners in China. The data for the study were hand-collected by survey questionnaires in four cities across three provinces in China. We found three main results. First, small restaurant entrepreneurs were characterized by one of...
Barley (Hordeum vulgare) is an important component of heart-healthy whole grain diets because it contains β-glucan. All current US barley varieties with high β-glucan are spring habit and have waxy starch. Winter varieties have agronomic advantages but require low-temperature tolerance (LTT). Vernalization sensitivity (VS) is associated with higher levels of...
Fisheries bycatch threatens populations of marine megafauna such as marine mammals, turtles, seabirds, sharks and rays, but fisheries impacts on non-target populations are often difficult to assess due to factors such as data limitation, poorly defined management objectives and lack of quantitative bycatch reduction targets. Limit reference points can be...
Phylogenetic analyses of assemblage membership provide insight into how ecological communities are structured. However, despite the scale-dependency of many ecological processes, little is known about how assemblage and source pool size definitions can be altered, either alone or together, to provide insight into how ecological diversity is maintained. Moreover, although...
We find that increases in implied market volatility (a proxy for market fear) have a significant impact on returns of bank stocks, above and beyond systematic risk proxied by the expected excess market return during a bad economic regime. Large bank returns are favorably affected by increases in implied market...
The strength-normalized fatigue endurance strength of the bulk metallic glass (BMG) Zr₅₂.₅Cu₁₇.₉Ni₁₄.₆Al₁₀Ti₅ (Vitreloy 105) has been reported to be the highest for any BMG; however, to date, there has been no explanation of why this material is so much better than other Zr-based compositions. In this study, the fatigue-crack growth...
PURPOSE—We examined the effects of Positive Action (PA), a school-based social-emotional learning and health promotion program, on the emotional health of predominately low-income and ethnic minority urban youth.
METHODS—The study was a matched-pair, cluster-randomized controlled trial involving 14 Chicago public schools. Outcomes were assessed over a 6-year period of program...
Invasions have increased the size of regional species pools, but are typically assumed to reduce native diversity. However, global-scale tests of this assumption have been elusive because of the focus on exotic species richness, rather than relative abundance. This is problematic because low invader richness can indicate invasion resistance by...
Feminist theorists have shown that knowledge is embodied in ways that make a
difference in science. Intemann properly endorses feminist standpoint theory over
Longino’s empiricism, insofar as the former better addresses embodiment. I argue that
a pragmatist analysis further improves standpoint theory: Pragmatism avoids the radical
subjectivity that otherwise leaves...
This guide provides nutrient and lime recommendations for establishment of turf and forage perennial ryegrass grown for seed in western Oregon.
