Multimedia networking is one of the most exciting developments in today's Internet. Streaming technology; which allows the player to start playing audio/video data immediately instead of waiting for the entire file to be downloaded, presents an attractive vehicle for the distribution of multimedia content over the Internet. However, transmitting real-time...
With sequential computing technology reaching its speed limits, parallel processing is emerging as the key to very-high-speed computation. However, developing a parallel program is by no means a simple task; neither is analyzing the performance of parallel programs.
C* is a high-level data-parallel language that hides explicit message passing and...
The reaction of fluid or gas flowing around an obstacle is a common engineering problem. Computer simulations are often used to measure and visualize the physical processes involved. In this report, we will discuss a parallel implementation of a simulation using the Smooth Particle Hydrodynamics (SPH) approach to fluid flow....
The export of organic carbon from the surface ocean by sinking particles is an important, yet
highly uncertain, component of the global carbon cycle. Here we introduce a mechanistic assessment of the
global ocean carbon export using satellite observations, including determinations of net primary production
and the slope of the...
Ampelisca eschrichtii are among the most important prey of the Western North Pacific gray whales, Eschrichtius robustus. The largest and densest known populations of this amphipod occur in the gray whale’s Offshore feeding area on the Northeastern Sakhalin Island Shelf. The remote location, ice cover and stormy weather at the...

Background: We present a model for reporting accelerometer paradata (process-related data produced from survey administration) collected in the International Study of Childhood Obesity Lifestyle and the Environment (ISCOLE), a multi-national investigation of >7000 children (averaging 10.5 years of age) sampled from 12 different developed and developing countries and five continents....

Background: High birthweight is an established risk factor for childhood leukaemia.
Its association with other childhood cancers is less clear, with studies hampered by low
case numbers. Methods: We used two large independent datasets to explore risk associations between
birthweight and all subtypes of childhood cancer. Data for 16 554...
Mammalian flavin-containing monooxygenase (FMO) is active towards many drugs with a heteroatom having the properties of a soft nucleophile. Thiocarbamides and thiones are S-oxygenated to the sulfenic acid which can either react with glutathione and initiate a redox-cycle or be oxygenated a second time to the unstable sulfinic acid. In...
Fungal hyphae are among the most highly polarized cells. Hyphal polarized
growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily
in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex
is required for tethering of secretory vesicles to the apical plasma membrane. We...
