(See (Enderton, 2001) and (Manzano, 2005) for more about many-sorted first-order logic).
Some scientists are concerned with taxonomy, sorting like with like without regard to how the sorted items came about or how they work.
About 0.5 g of sex-sorted adult flies was cross-linked with 1.8% formaldehyde in cross-linking solution (50 mM pH 8.0 HEPES buffer, 1 mM EDTA, 0.5 mM EGTA, and 100 mM NaCl) for 20 minutes at room temperature on a shaker.
He rejected plastic surgery to avoid losing his place in the team: "I can't see myself going for [surgery] at the moment because I've got bigger things to worry about than getting this sorted".
Second, it has been shown that about 10-20% of sorted X1's could not be labeled for piwi-1 RNA in previous publications (Reddien, 2005, and Eisenhoffer, 2008), which may skew results if those unlabeled dividing cells were still PIWI-1+.
We have developed a preliminary knowledge base for qualitative reasoning about containers, expressed in a sorted first-order language of time, geometry, objects, histories, and actions.
My feeling is that Malian music draws attention to the richness of that social capital, and if you listen to it, you realise something about this society really is sorted".
