1654 Urokinase and Inhibitor in Human Monocytes

Piasminogen activators (PA) l are thought to play a role in the proteolytic events associated with cell migration and tissue destruction and remodeling (1), in particular in the context of inflammation (2). Indeed, monocytes and macrophages from both human and murine origin produce PA (3, 4), and the secretion of these enzymes has been linked with the participation of mononu¢lear phagocytes in ...

Adaptive Combination of Behaviors in an gent

Agents are of interest mainly when confronted with complex tasks. We propose a methodology for the automated design of such agents (in the framework of Markov Decision Processes) in the case where the global task can be decomposed into simpler -possibly concurrentsub-tasks. This is accomplished by automatically combining basic behaviors using Reinforcement Learning methods. The main idea is to ...

Shannon’s celebrated source coding theorem can be viewed as a “one-sided law of large numbers.” We formulate second-order noiseless source coding theorems for the deviation of the codeword lengths from the entropy. For a class of sources that includes Markov chains we prove a “one-sided central limit theorem” and a law of the iterated logarithm.

The Gent–McWilliams Skew Flux

This paper formulates tracer stirring arising from the Gent–McWilliams (GM) eddy-induced transport in terms of a skew-diffusive flux. A skew-diffusive tracer flux is directed normal to the tracer gradient, which is in contrast to a diffusive tracer flux directed down the tracer gradient. Analysis of the GM skew flux provides an understanding of the physical mechanisms prescribed by GM stirring,...
