I recently learned that Volker was in an accident while biking. The car won the encounter and he had a subdural hematoma. But he is now recovering and should be recovered within a short while. The accident occurred just before Basel and prevented his attendance.
Glad to hear he is recovering.

Sorry for the delay in responding to this notice -- I've been away from the forum for a few weeks. Best wishes for a speedy recovery!
Best,
Gary
