Wired Wired World: Breaking the Mosaic Mold
Many of us have been watching the recent goings-on at Netscape and wondering what it all means. The layoffs in general, the cancellation of in-house Java development, and the Communicator source-code giveaway have received most of the attention, but another unsettling item has gone largely unnoticed. As of February 1998, Netscape no longer maintains a staff of usability engineers. At its zenith...
متن کاملEditorial: Wired for Life
Fossil fuels and fossil fuel derived chemicals are limited, non-renewable, and foreseen to run out in the near future. To find viable solutions for the production of renewable fuels and chemicals, significant efforts are being made by the scientific community. For example, some microorganisms have been shown to produce fuels or chemicals using renewable electricity charged electrodes as electro...
متن کاملWired Geometric Routing
Routing substrates for overlay networks are an important building block for large distributed applications. Many existing substrates are based on a random identifier space and therefore do not respect node locality when routing data. This can lead to lower performance for locality-sensitive applications, such as web caching, distributed gaming, and resource discovery. This paper examines the pr...
متن کاملWired for obesity?
The central nervous system (CNS) plays an important role in the regulation of appetite, energy expenditure, and body weight. Understanding the neural pathways involved is essential to the development of mechanismbased approaches to the prevention and treatment of obesity and diabetes (Fig. 1). Recent advances in MRI of fast acquisition sequences and image-processing software now enable us to no...
متن کاملCross-wired lamplighter groups
We give a necessary and sufficient condition for a locally compact group to be isomorphic to a closed cocompact subgroup in the isometry group of a Diestel–Leader graph. As a consequence of this condition, we see that every cocompact lattice in the isometry group of a Diestel–Leader graph admits a transitive, proper action on some other Diestel–Leader graph. We also give some examples of lattic...
