We propose a simultaneous equation system with GARCHX errors to model the contemporaneous relations among Asian and American stock markets. We thus evaluate the correlation matrix over rolling windows and introduce a correlation matrix distance which allows a simple graphical analysis of contagion. The empirical analysis on Asian and American stock markets shows some evidences of contagion.

MOTIVATION We explored the feasibility of using unaligned rRNA gene sequences as DNA barcodes, based on correlation analysis of composition vectors (CVs) derived from nucleotide strings. We tested this method with seven rRNA (including 12, 16, 18, 26 and 28S) datasets from a wide variety of organisms (from archaea to tetrapods) at taxonomic levels ranging from class to species. RESULT Our res...

Analysis of standard clinical electrocardiogram signal is one of the basic routine tests for preliminary screening of cardiac disorders. This work deals with classification of normal and IMI (Inferior Myocardial Infarction) ECGs and presents a method for analysis of Electrocardiogram (ECG) patterns using Cross Correlation. The application of cross correlation to two ECG beats and the cross exam...
