Query: Some Remarks on Lower Bounds for Queue Machines (Preliminary Report)   We first give an improved lower bound for the deterministic online simulation
of tapes or pushdown stores by queues. Then we inspect some proofs in a
classical work on queue machines in the area of Formal Languages and outline
why a main argument in the proofs is incomplete. Based on descriptional
complexity, we show the intuition behind the argument to be correct.
