In the
previous experiment three CA oscillated asynchronously. The
phase shift was achieved by a transfer of resources between the CA. Now
the CA did not exchange resources and therefore oscillated synchronously.
They discharged their resources into the immediate neighborhood. The
set point >=20 .
Infection and Injury
Whenever CA-2 was at state 22, a virus attached to its structure
whereupon CA-2 injured CA-3. Four of its left most cells were
set to zero (white). In other words, CA-2 state 22 served as a receptor
for the virus. Following injury CA-3
changed and attempted to regain
its healthy structure. However whenever CA-2 reached its state 22 it
became activated injuring CA-3 again and again. CA-4 was not affected.
Repair
The stem process (CA-1)
continually compares the structures of transitory processes. When
detecting that CA-2 and CA-3 differed it eliminated CA-3 by apoptosis
and planted a zygote instead. However the new CA-3 was injured
again and again. The perturbation poses a threat to the proliferon.
In order to regain a solution, the stem process applied a new strategy.
It changed the resource flow between the CA. CA-2 and CA-4 stopped
discharging their resources into their neighborhood. In addition
CA-4 transferred its resources to CA-2.
CA-2 changed its structure and the virus could not attach to it anymore. The particular structure which interacted with the virus is called a receptor. By transferring resources into CA-2 its receptor changed, and could not be activated by the virus. Now CA-3 was injured only once and could regain its healthy oscillations. CA-4 which donated all its resources to CA-2 dwindled and became atrophic.
In order to check whether transitory processes oscillate synchronously,
the stem process assigned CA-2 as a reference with which other processes
were compared. In this setting CA-2 serves as memory which is essential
for detecting injury and initiating repair by the stem process.
Immunity
The experiment illustrates a novel aspect of immunity.
Redundancy
The experiment illustrates a new kind of redundancy. In linear machines
when redundant parts replace broken parts, each performs the same task
like the broken part. Here the function of each redundant CA emerges and
is different. Initially all three transitory CA were the same. Following
injury each undertook a different task.
