Seamless connectivity in 4G wireless networks requires the development of intelligent proactive mechanisms for efficiently predicting vertical handovers. Random device mobility patterns further increase the complexity of the handover process. Geographical topologies such as indoor and outdoor environments also exert additional constraints on network coverage and device mobility. The ability of ...

OBJECTIVES The Brazilian constitution guarantees the right to health, including access to medicines. In May 2004, Brazil's government announced the "Farmácia Popular" Program (FPP) as a new mechanism to improve the Brazilian population's access to medicines. Under FPP, a selected list of medicines is subsidized by the government and provided in public and private pharmacies. The aim of this stu...

The genetic structure of swordfish (Xiphias gladius) in the Pacific Ocean was assessed by analyzing 594 individuals from 6 different regions, genotyped with 13 microsatellite loci. The results showed very low genetic differentiation among the different geographical areas, which was not statistically significant. There was a slight evidence for isolation by distance across a U-shaped corridor, a...

The World Health Organization's (WHO's) World Health Report 2010, "Health systems financing, the path to universal coverage," promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

Coverage control is one of the most fundamental issues in directional sensor networks. In this paper, the coverage optimization problem in a directional sensor network is formulated as a multi-objective optimization problem. It takes into account the coverage rate of the network, the number of working sensor nodes and the connectivity of the network. The coverage problem considered in this pape...
