Query: On the Aging Dynamics in an Immune Network Model   Recently we have used a cellular automata model which describes the dynamics
of a multi-connected network to reproduce the refractory behavior and aging
effects obtained in immunization experiments performed with mice when subjected
to multiple perturbations. In this paper we investigate the similarities
between the aging dynamics observed in this multi-connected network and the one
observed in glassy systems, by using the usual tools applied to analyze the
latter. An interesting feature we show here is that the model reproduces the
biological aspects observed in the experiments during the long transient time
it takes to reach the stationary state. Depending on the initial conditions,
and without any perturbation, the system may reach one of a family of
long-period attractors. The pertrubations may drive the system from its natural
attractor to other attractors of the same family. We discuss the different
roles played by the small random perturbations (noise) and by the large
periodic perturbations (immunizations).
