Breaking the Deadlock
Many of the proposed approaches to the semantic web have a substantial drawback. They are all based on the idea that web pages (or more generally, resources), will contain semantic annotations that would allow remote agents to access them. However the problem of the creation of those annotations is seldom addressed. Manual creation of the annotations is not a feasible option, except in a few ex...
متن کاملBreaking the Cloud Parameterization Deadlock
NOVEMBER 2003 AMERICAN METEOROLOGICAL SOCIETY | C LOUDS AND CLIMATE: A PROBLEM THAT REFUSES TO DIE. Clouds of many varieties fill the global atmosphere (Fig. 1). They are composed of drops and crystals with scales on the order of microns to millimeters. They are associated with convection and turbulence on scales of meters to kilometers. They are organized within mesoscale and synoptic-scale dy...
متن کاملSpontaneous deadlock breaking on amoeba-based neurocomputer
Any artificial concurrent computing system involves a potential risk of "deadlock" that its multiple processes sharing common computational resources are stuck in starved conditions, if simultaneous accesses of the processes to the resources were unconditionally permitted. To avoid the deadlock, it is necessary to set up some form of central control protocol capable of appropriately regulating ...
متن کاملBreaking the Deadlock of Molecular Chaperones
Protein folding in the cell requires ATP-driven chaperone machines. It is poorly understood, however, how these machines fold proteins. Here we propose that the conserved Hsp70 and Hsp90 chaperones support formation of the folding nucleus by providing a gradient of decreasing hydrophobicity. Early on the folding pathway Hsp70 uses its highly hydrophobic binding pocket to recover a stalled, unpr...
متن کاملBreaking the Deadlock: Improving Water-Release Policies on the Delaware River Through Operations Research
The Delaware River provides half of New York City’s drinking water, is a habitat for wild trout and American shad, and has suffered three major floods in the last five years. The water releases from three New York City dams on the Delaware River’s headwaters impact the reliability of the city’s water supply, the potential for floods, and the quality of the aquatic habitat. This project’s object...
