Active IP Networking : Towards Self - organized

Active Interfaces through Software Agents

This paper concerns the development of an interface environment to help users in repetitive tasks in o ce work. The main ideas in the project concern: the development of active interfaces that autonomously perform tasks minimizing the interaction with the user; the use of the agent-oriented paradigm to provide both distributedness and incrementality of the software environment. The paper quickl...

Porphyrin self-assembly at electrochemical interfaces: role of potential modulated surface mobility.

The self-assembly of 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine (TPyP) on Au(111) electrodes was investigated. The adlayer structure was found to depend on the electrode potential. At positive potentials (>0.5V(SCE)), a disordered layer of TPyP is formed on the Au(111) electrode. STM images showed that the disordered molecules are immobile. At negative potentials (-0.2V(SCE)), however, the mo...

Self-organized chaos through polyhomeostatic optimization.

The goal of polyhomeostatic control is to achieve a certain target distribution of behaviors, in contrast to homeostatic regulation, which aims at stabilizing a steady-state dynamical state. We consider polyhomeostasis for individual and networks of firing-rate neurons, adapting to achieve target distributions of firing rates maximizing information entropy. We show that any finite polyhomeostat...

Critical Self-Organized Self-Sustained Oscillations in Large Regulatory Networks: Towards Understanding the Gene Expression Initiation

In this paper, a new model of self-organized criticality is introduced. This model, called the gene expression paradigm, is motivated by the problem of gene expression initiation in the newly-born daughter cells after mitosis. The model is fundamentally different in dynamics and properties from the well known sand-pile paradigm. Simulation experiments demonstrate that a critical total number of...
