Start-of-season data are more and more used to qualify the land surface phenology trends in relation with climate variability and, more rarely, with human land management. In this paper, we compared the phenology of rangeland vs cropped land in the Sahel belt of Africa, using the only currently available global phenology product (MODIS MCD12Q2 – Land Cover Dynamics Yearly), and an enhanced crop...

According to Ravallion1 84 % of China’s population lived below the international poverty line of $1.25 per day in 1981, when only four countries, Cambodia, Burkina Faso, Mali and Uganda had a higher headcount index than China. However, The Economist (Jun 1st 2013) shows that China pulled 680 million people out of misery and reduced its extreme-poverty rate to 10% through economic growth in the ...

Methods First, APPS developed a situational analysis tool at a cross-country workshop to define questions for systematic data collection on 12 patient safety action areas. Second, each APPS hospital formed teams to conduct analyses. Third, an external expert worked on-site with each team to validate findings. Finally, results were shared at a second cross-country Workshop, forming the basis for...

Millets are extremely important in the African SAT (semi-arid tropics), produced in 18.50 million ha by 28 countries covering 30% of the continent. This is a significant 49% of the global millet area, with a production of 11.36 million tons by 1994. There are nine species which form major sources of energy and protein for about 130 million people in SSA (Sub-Saharan Africa). Among these, only f...

Introduction: An accurate and fast radiation dose calculation is essential for successful radiation radiotherapy. The aim of this study was to implement a new graphic processing unit (GPU) based radiation therapy treatment planning for accurate and fast dose calculation in radiotherapy centers. Materials and Methods: A program was written for parallel runnin...

The Graphics Processing Unit (GPU) is now commonly used for graphics and data-parallel computing. As more and more applications tend to accelerate on the GPU in multi-tasking environments where multiple tasks access the GPU concurrently, operating systems must provide prioritization and isolation capabilities in GPU resource management, particularly in real-time setups. We present TimeGraph, a ...
