INTRODUCTION Ten viral genotypes (A-J) distributed in all continents have been described for hepatitis B virus (HBV). One of the methodologies for determining the viral genotype is the restriction fragment length polymorphism (RFLP) technique, a simple and relatively inexpensive method, albeit with some limitations. OBJECTIVE The initial objective of the project was to identify the HBV genoty...

Why are we still struggling to control the devastating effects of childhood tuberculosis? This disease has been with us since ancient times and yet, even with known effective prevention and treatment strategies, much of the world has unacceptable levels of childhood morbidity and mortality due to tuberculosis. As expected, progress in identification and treatment has occurred primarily in high-...

In this note we explore a useful equivalence relation for the delay distribution in the G/M/1 queue under two different service disciplines: (i) PS (Processor Sharing); and (ii) ROS (Random Order of Service). We provide a direct probabilistic argument to show that the sojourn time under PS is equal (in distribution) to the waiting time under ROS of a customer arriving to a non-empty system. We ...
