Martha Grahm reputedly said, “a dancer is an ‘athlete of God’” (Theys, 2010). Yet dance and exercise and sport science (herein referred to as exercise science) are often viewed as unique entities, sometimes dividedly so. Our contention is that dance and exercise science mutually benefit when the two disciplines are...
Early adulthood is a time of transition when large segments of the population embrace new roles and show decreases in behaviors and problems thought to underlie suicide risk. Still, other segments show emergent or worsening psychopathology per-haps exacerbated by age-related disconnection from prior relational and institutional supports. Suicide prevention efforts...
We use density and microstructure data to characterize the properties and physical setting of optical thin layers observed over the New Jersey shelf in the summer of 2006.

There are about 80 million single-family dwellings (SFDs) in the United States, predominantly of wood-frame construction. Of these, 68% are owner-occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all the houses in...
In opening our eyes to the unseen wonders of the ocean Jacques Cousteau is thought to have said, “People protect what they love.” A variation, perhaps, on the words of the Senegalese poet and naturalist Baba Dioum: “In the end, we will conserve only what we love. We will love...
An important question in the study of Riemannian manifolds of positive sectional curvature is how to distinguish manifolds that admit a metric with non-negative sectional curvature from those that admit one of positive curvature. Surprisingly, if the manifolds are compact and simply connected, all known obstructions to positive curvature are...
Many behaviors and substances have been purported to induce labor. Using data from the Third Pregnancy,
Infection, and Nutrition cohort, we focus on 663 women who experienced spontaneous labor. Of
the women who reported a specific labor trigger, 32% reported physical activity (usually walking), 24% a
clinician-mediated trigger, 19% a...
Total organic carbon (TOC) content of marine sediments represents residual carbon, originally derived from terrestrial and marine sources, which has survived seafloor and shallow subseafloor diagenesis. Ultimately, its preservation below the sulfate reduction zone in marine sediments drives methanogenesis. Within the gas hydrate stability zone (GHSZ), methane production along continental...

Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...
SUMMARY:
1. Understanding how predators select their prey can provide important insights into community structure and dynamics. However, the suite of prey species available to a predator is often spatially and temporally variable. As a result, species-specific selectivity data are of limited use for predicting novel predator–prey interactions because they...
Lepidopteran nucleopolyhedroviruses are members of the Baculoviridae and have been categorized as having two morphotypes of occluded virions: multiple nucleocapsids or single nucleocapsids within the virion envelope. Although it is a definitive characteristic of specific viruses, it appears to lack a defined genetic basis and is independent of virus phylogeny....
More than 1.2 million people worldwide require regular hemodialysis therapy to treat end stage renal failure. Current hemodialysis systems are too expensive to support at-home hemodialysis where more frequent and longer duration treatment can lead to better patient outcomes. The key cost driver for hemodialysers is the cost of the...
Coastal foredunes protect lives, infrastructure, and ecosystems during severe storms. A range of approaches, ranging from simple (e.g., geometric) to complex (e.g., process-based) predictive models, have been developed to quantify overtopping and foredune retreat during storms.

Butterfly populations and communities were analyzed in response to treatments (prescribed fire, mechanical, herbicide) designed to restore sagebrush steppe...
Polyandry is a source of sexual conflict and males often try to limit female promiscuity. Consequently, male manipulation of receptivity via antiaphrodisiacs and copulatory plugs that prevent female remating can be a source of sexual conflict. This sexual conflict may be intensified when females must remate for fertility insurance. Male...
In addition to well established properties that control the presence or absence of the hydrate stability zone, such as pressure, temperature, and salinity, additional parameters appear to influence the concentration of gas hydrate in host sediments.
