First, the open analysis is appropriate for some copular constructions but not for others, even within the same language. Second, the same construction can be open in some languages and closed in others. Third, we c...

Results of burr hole and open or closed suction drainage for chronic subdural hematomas in adults.

It has long been known that lower eukaryotes and higher eukaryotes achieve this in strikingly different ways.
