However, one serious potential drawback in integrating large scale indexing would be data contamination due to index switching, or the transfer of an index from one individual to the sequencing read of another individual.
However, extracting the signal from such large-scale indices for modeling such complex systems is significantly difficult.
Moreover, of the few studies that do address this specific issue, many have used national or other large-scale indices of population size in analyses of urbanization [ 8, 9], which overlooks potentially important spatial variation in source populations [ 30].
This paper contributes initial results of our research towards obtaining base rates using the data available at Ohloh (a large-scale index of OSS projects).
At the study area scales, we first averaged trapping indices per crop type then calculated a large-scale index by averaging densities across crop types [ 26].
The distributed Sciencenet software platform has the following key elements: (1) A large-scale index technology capable of handling billions of documents belonging to the scientific web.
For our analyses we have chosen, as large scale climate indices, the winter North Atlantic Oscillation NAOO) index, because the NAO it is the dominant winter mode in the Atlantic area [62], with effects reaching into the Mediterranean Sea [63].
Image annotation plays a significant role in large scale image understanding, indexing and retrieval.
The predictive variables were: monthly rainfall totals, mean temperature, minimum temperature, maximum temperature and evapotranspiration, which were supplemented by large-scale climate indices (Southern Oscillation Index, Pacific Decadal Oscillation, Southern Annular Mode and Indian Ocean Dipole) and the Sea Surface Temperatures (Nino 3.0, 3.4 and 4.0).
The Genetic Programming approach is found to capture the complex relationship between the monthly Indian Summer Monsoon Rainfall and large scale atmospheric circulation pattern indices – ENSO and EQUINOO.
We provide novel analyses that link local, regional and basin scale hydrological properties with two major indicators of large scale climate, the North Atlantic Oscillation index and the Northern Hemisphere Temperature index, suggesting that the Mediterranean shift is part of a large scale change in the Northern Hemisphere.
