Limit cycle frequencies in oscillatory systems in biology may form templates in which forms can be fixed in structures which provide instructions for the next stage. (religion-online.org)
Determining significant cycles frequencies is interesting because it does allow prediction. (realclimate.org)
The late 20th century divergence is partly due to local anthropogenic warming and partly to other factors, such as longterm multicentennial linear trend in solar cycle frequency (thermal inertia of oceans and ice). (judithcurry.com)
