A number of microarray studies assume gene expression data to be independent of one another. In this report, we provide evidence of correlation in cDNA microarray gene expression data using classical power spectral analysis and the sophisticated detrended fluctuation analysis (DFA). Such...

Further, two scaling regimes are found, although the characteristic laws are quite … similar ones. Next, the multi-affine scaling properties are confirmed. The scaling properties of the cloud base height profile …

The long episode of negative values in the North Atlantic Oscillation (NAO) index during the winter season 2009–2010 has attracted more attention to its predictability. Previous analyses (Fernández et al. (2003) [16] and Caldeira et al. (2007) [25]) by this same author group have...
