In this paper, we study the transient behavior of a level dependent PH/PH/1/K queue during the busy period. We derive in closed-form the joint transform of the length of the busy period, the number of customers served during the busy period, and the number of losses during the busy period. We differentiate between two types of losses: the overflow losses that are due to a full queue and the los...

We present preliminary measurements of branching fractions and CP -asymmetry parameters in twoand three-body charmless hadronic B decays. The available data sample consists of 227 million Υ (4S) → BB decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e− collider at SLAC. We establish the observation of the decays B → ππ and B → KK and constrain the CKM angle α with a ful...

INTRODUCTION As patient volumes continue to increase, more attention must be paid to skills that foster efficiency without sacrificing patient safety. The emergency department is a fertile ground for examining leadership and management skills, especially those that concern prioritization in multi-patient environments. We sought to understand the needs of emergency physicians (EPs) and emergency...

A systematic study of a wide class of nonrelativistic models of bb quarkonia is described. It is found that the potential V (r) = 0.706380(√ r − 0.460442 r) + 8.81715 (all in GeV) with the b-quark mass m b = 4.80303 GeV gives a satisfactory description of the experimental data below the threshold for strong decays (χ 2 /DF = 6.5/7). Limitations and implications of this observation are discussed.

The recent measurements of the CKM angle γ by the BABAR experiment are reported. The analyses have been performed using the complete sample of 468 million BB pairs collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B factory during the years 1999-2007.

In this paper we solve the problem of characterizing inversion multi-graphs (cf. BB]) associated to aane permutations.
