Availability in Global Peer-To-Peer Storage Systems
The recent popularity of peer-to-peer (P2P) systems for file sharing has led to increased demand for higher data availability from such systems. Measurements of popular P2P systems indicate that a large number of hosts appear to be available on a cyclic basis, and their availability shows great heterogeneity. This paper proposes a cooperative storage technique which employs erasure coding schem...
متن کاملGlobal patterns in availability of emergency obstetric care.
OBJECTIVE This paper examines the availability of basic and comprehensive emergency obstetric care (EmOC), interventions used to treat direct obstetric complications. Determining what interventions are provided in health facilities is the first priority in analyzing a country's capabilities to treat obstetric emergencies. There are eight key interventions, six constitute basic EmOC and all eigh...
متن کاملWater availability predicts forest canopy height at the global scale.
The tendency of trees to grow taller with increasing water availability is common knowledge. Yet a robust, universal relationship between the spatial distribution of water availability and forest canopy height (H) is lacking. Here, we created a global water availability map by calculating an annual budget as the difference between precipitation (P) and potential evapotranspiration (PET) at a 1-...
متن کاملGlobal climate change and tree nutrition: influence of water availability.
The effects of global climate change will regionally be very different, mainly causing considerable changes in temperature and water availability. For Central Europe, for example, increased temperatures are predicted, which will cause increased frequencies and durations of summer drought events. On the other hand, the predicted changes in precipitation patterns will lead to enhanced rainfall du...
متن کاملThe global availability of n-3 fatty acids.
OBJECTIVES To assess the validity of FAO data on the availability of fish and vegetable oils as an indicator of national n-3 fatty acid (FA) intake and to estimate the worldwide population living in countries with low n-3 FA intake. DESIGN Levels of the essential FA α-linolenic acid (ALA) and DHA, measured by GC in adipose tissue from participants in the present study and from published studi...
