The present meta-analysis aimed to critically review the current evidence on the efficacy of propranolol in the management of airway haemangiomas, and explore potential adverse events and treatment failures.

Computer systems with finite request sourcing have been analyzed in the past using infinite source queues or an M/M/1/N queue, both of which may lead to large errors. This paper develops approximations to the response times of the M/G/1/N and GI/G/1/N queues, allowing application of these more realistic models in performance analyses of computer systems.
