Besides the methodological need for ALIfold (see Material and Methods), the restriction to conserved sites restricts the analysis to sites potentially under considerable strong selection.
Normally, this restricts the analysis to elements where the excitation is at the element ends.
The final column in each group restricts the analysis to those who took a usual course load, in this case eight courses during the academic year.
However, even if one restricts the analysis to identical, globally-coupled oscillators, there are very few theoretical results and they mostly concern fully-synchronised regime or specific types of neurons (e.g. the leaky integrate-and-fire model) [4, 7, 8].
Athens and Galway are "polar cases" if one restricts the analysis to the three most popular schemes B, C, and D, whereas findings at the other sites lie in between.
In order to disentangle sibling and neighbor correlations, Sacerdote (2007) restricts the analysis to adoptees, which are assumed to be randomly assigned to families without inheriting any genetic characteristic.
