There were twice as many women (247) as men (121), and two thirds of the patients were in the 15-35 age group. Ninety-five per cent had taken a drug overdose, most commonly one(More)
1. The incidence of non-fatal deliberate self-harm throughout the City of Bristol during 1972 and 1973 was assessed by means of a survey of patients presenting to Accident and Emergency Departments of hospitals in the area.

We study finite automata with both nondeterministic and random states (npfa's). We restrict our attention to those npfa's that accept their languages with a small probability of error and run in polynomial expected time. Equivalently , we study Arthur-Merlin games where the players are limited to polynomial time and constant space. Dwork and Stockmeyer(More)
