Universe B had more stable oscillations, but a lower average population.
2.
Instead of them, stable oscillations or other types of attractors may appear.
3.
As a result of this behavior feedback within the population, a pattern of stable oscillations emerges between the different forms of parental care.
4.
This network was designed from scratch to exhibit a stable oscillation which is reported via the expression of green fluorescent protein, and hence acts like an electrical oscillator system with fixed time periods.
5.
A 2002 study of Huygens'observations show that an antiphase stable oscillation was somewhat fortuitous, and that there are other possible stable solutions, including a " death state " where a clock stops running, depending on the strength of the coupling between the clocks.
