Current-generation Massively Multiplayer Online Games (MMOG), such as World of Warcraft, Eve Online, and Second Life are mainly built on distributed client-server architectures with server allocation based on sharding, static geographical partitioning, dynamic micro-cell scheme, or optimal server for placing a virtual region according to the geographical dispersion of players. This paper review...

A key issue for many countries and even for international organizations including "The World Bank" and "The United Nations" is how to attack poverty. In many countries of the world, millions of people are hungry, lacking shelter and clothing, sick and uncared for, illiterate and not schooled. These, all cause to reduce efficiency and productivity of labor, and hence decrease income. Also, being...

We examined the association between Household Food Insecurity (HFI), weight for height z-score (WHZ) and Body Mass Index for age z-score (BMI-Z) in a representative sample of children 0-60 months of age (n = 3,433) in five Brazilian geographical regions. Data were derived from the 2006-07 Brazilian Demographic and Health Survey. HFI was measured with the Brazilian Food Insecurity Scale. Associa...

Existing latency measurement-based geolocation techniques use the observed latencies from multiple landmarks to the target host to determine maximum bound or both the maximum and minimum bounds of ...

The influence of self-reported "race/color", geographical origin and genetic ancestry on the distribution of three functional CYP3A5 polymorphisms, their imputed haplotypes and inferred phenotypes was examined in 909 healthy, adult Brazilians, self-identified as White, Brown or Black ("race/color" categories of the Brazilian census). The cohort was genotyped for CYP3A5*3 (rs776746), CYP3A5*6 (r...

Distribution of hepatitis B virus (HBV) genotypes/subgenotypes is geographically and ethnologically specific. In the Indonesian archipelago, HBV genotype C (HBV/C) is prevalent with high genome variability, reflected by the presence of 13 of currently existing 16 subgenotypes. We investigated the association between HBV/C molecular characteristics with host ethnicity and geographical distributi...
