The stable nitrogen isotope ratio (dN) is an established indicator of trophic hierarchy in marine food-web studies. Most of these studies presume that spatial variation in the primary food source is negligible, although a water-depthrelated increase in dN of particulate organic matter (POM) has been found in many systems. We used the high-Antarctic Weddell Sea shelf and slope ecosystem to test ...

Journal of Clinical Sleep Medicine, Vol. 11, No. 6, 2015 Sleep is essential for optimal health. The American Academy of Sleep Medicine (AASM) and Sleep Research Society (SRS) developed a consensus recommendation for the amount of sleep needed to promote optimal health in adults, using a modifi ed RAND Appropriateness Method process. The recommendation is summarized here. A manuscript detailing ...

The oriental fruit fly, Bactrocera dorsalis, was initially recorded in Taiwan Island in 1912, and has dispersed to many areas in the Pacific-Asia region over the last century. The area of origin of the species may be confidently placed in South-East China. However, routes of range expansion to new areas and underlying population processes remain partially unclear, despite having been the subjec...

The response of soil microbial communities following changes in land-use is governed by multiple factors. The objectives of this study were to investigate (i) whether soil microbial communities track the changes in aboveground vegetation during succession; and (ii) whether microbial communities return to their native state over time. Two successional gradients with different vegetation were stu...

BACKGROUND There is little information on the detailed patterns of cervical screening uptake in older migrant women in Australia. This linkage study was performed to assess cervical screening participation in older migrants. METHODS We linked year 2000-2001 records for 14,228 Middle Eastern/Asian-born women 40-64 years of age, and an age and area matched random sample of 13,939 Australian-bor...

Multiplication is most commonly used operation in mathematics. Integer multiplication is used commonly in the real world, binary multiplication is the basic multiplication used for the integer multiplication. Systolic algorithms are the efficient algorithms to perform the binary multiplication [1]. Systolic array is an arrangement of processors in an array where data flows synchronously across ...

We determine the reachability properties of the embeddings in R of a directed path, in the graph-theoretic sense, whose edges have each been assigned a desired direction (East, West, North, South, Up, or Down) but no length. We ask which points of R can be reached by the terminus of an embedding of such a path, by choosing appropriate positive lengths for the edges, if the embedded path starts ...
