The slow β relaxation is understood to be a universal feature of glassy dynamics. Its presence in bulk metallic
glasses (BMGs) is evidence of a broad relaxation time spectrum that extends to deep within the glassy state.
Despite the breadth of research devoted to this phenomenon, its microscopic origin is...
We studied the reliability and validity of the Columbia Suicide Severity Scale (C-SSRS).
Severely delinquent adolescent girls (n = 166) participated in a treatment trial and repeated
assessments over time. Lifetime suicide attempt history was measured using the C-SSRS in early
adulthood (n = 144; 7–12 years post-baseline). Nonclinician raters...
How do you test a program when only a single user, with no expertise in software testing, is able to determine if the
program is performing correctly? Such programs are common today in the form of machine-learned classifiers. We consider the
problem of testing this common kind of machine-generated program...
Saccharomyces cerevisiae contains three NAD⁺/NADH kinases, one of which is localized in
mitochondria and phosphorylates NADH in preference to NAD⁺. Strand et al (Euk. Cell
2:809 (2003)) reported that a yeast mutation in POS5, which encodes the mitochondrial
NADH kinase, is a mutator, specific for mitochondrial genes. Because of the...
We report here on recent developments and advances in pore-scale x-ray tomographic imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid flow, i.e., the displacement of one immiscible fluid by another inside a porous material, which is of central importance to many natural and engineered processes....

Innovativeness can help companies differentiate themselves, with the ultimate goal of securing survival and improving performance. Modern theories in organizational behavior look at innovation as something that starts with individual creativity but that is also affected by the work environment. Using one broad industry sector, the US forest products industry,...

The extracellular colorants produced by Chlorociboria aeruginosa, Scytalidium cuboideum, and Scytalidium ganodermophthorum, three commonly utilized spalting fungi, were tested against a standard woodworker’s aniline dye to determine if the fungal colorants could be utilized in an effort to find a naturally occurring replacement for the synthetic dye. Fungal colorants were...
Like most ecological communities, aspen (Populus tremuloides) forests are influenced by a synergy of bottom-up (resources-driven) and top-down (predator-driven) processes. Since the 1920s, ecologists have observed the decline of many aspen communities throughout the Intermountain West. The extent and possible drivers of this decline are topics of much recent scientific...
Body size is known to correlate with many aspects of life history in birds, and this knowledge can be used to manage and conserve bird species. However, few studies have compared the wintering ecology of sympatric subspecies that vary significantly in body size. We used radiotelemetry to examine the relationship...
The authors investigate atmospheric internal gravity waves (IGWs): their generation and induction of global intermittent turbulence in the nocturnal stable atmospheric boundary layer based on the new concept of turbulence generation discussed in a prior paper by Sun et al. The IGWs are generated by air lifted by convergence forced...
Both laboratory analyses and on-farm quick tests of manure nutrient content play an important role in manure management. Laboratory testing is the most reliable method of manure nutrient testing and is valuable for long-term planning and as a check on quick test results.
A great deal of research has documented racial disparities in imprisonment rates in the United States, but little work has been done to understand the process by which inmates are assigned to individual correctional facilities. This article extends research on racial disparities in imprisonment rates to consider racial disparities in...
The forest sector and the global financial crisis (GFC) provide a unique setting for investigating the relationships among market orientation, innovativeness and firm performance. While most of the extant literature suggests that market orientation helps a firm build its innovativeness, we suggest that in the production oriented forest sector, especially...

Extreme water levels generating flooding in estuarine and coastal environments are often driven by compound events, where many individual processes such as waves, storm surge, streamflow, and tides coincide. Despite this, extreme water levels are typically modeled in isolated open-coast or estuarine environments, potentially mischaracterizing the true risk of flooding...
Estimates of mass transfer timescales from 316 solute transport experiments reported in 35 publications are compared to the pore-water velocities and residence times, as well as the experimental durations. New tracer experiments were also conducted in columns of different lengths so that the velocity and the advective residence time could...
The objective of this study was to investigate the multiple uses and cognitive importance of edible weeds in Northeast Thailand. Research methods included focus group discussions and freelistings. A total of 43 weeds consumed as vegetable were reported, including economic, naturalized, agricultural and environmental weeds. The weedy vegetables varied considerably...
