Injury and Repair - 2

This is a continuation of the previous experiment  in which a virus triggered CA-2 to injure CA-3. During repair CA-4 transferred its resources to CA-2, changing its structure (receptor), pr venting the virus from  triggering an injury.  The present experiment illustrates two additional repair strategies. We start with three transitional  processes. The set point of CA-2 and CA-3 >= 20. CA-4 is isolated and its s. p. >=24.

The repair is achieved by transferring resources from CA-4 and CA-3 to CA-2. After a brief transient CA-2 becomes an isolated process whose structure (receptor) is not recognized by the virus, and injury stops.

Resource accumulator

The task of CA-4 is to accumulate resources and when needed transfer them to the infected CA-2. We may distinguish between two kind of oscillators: Type-1 whose existence is brief. When it dies it loses its resources and is replaced with a zygote (v. WOB: Demand = 9). Type-2 dilates and shrinks and does not die. It can therefore accumulate some of its resources. (v. WOB: Demand = 1). An injury may trigger the formation of either type. Since repair involves resource exchange between CA, it is of advantage to grow a special CA-4 which accumulates resources. The next graph depicts its resource accumulation.

A solution for small CA

When the injured CA are small like in the next experiment CA-4 resources are insufficient to repair the injury. The only way to change CA-2 structure is by raising its set point.
