Universal 1/f noise, cross-overs of scaling exponents, and chromosome specific patterns of GC content in DNA sequences of the human genome
Wentian Li, Dirk Holste
Spatial fluctuations of guanine and cytosine base content (GC%) are studied by spectral analysis for the complete set of human genomic DNA sequences. We find that (i) the 1/f^alpha…
An Unusual 500,000 Bases Long Oscillation of Guanine and Cytosine Content in Human Chromosome 21
Wentian Li, Dirk Holste
An oscillation with a period of around 500 kb in guanine and cytosine content (GC%) is observed in the DNA sequence of human chromosome 21. This oscillation is localized in the rig…
How Many Genes Are Needed for a Discriminant Microarray Data Analysis ?
Wentian Li, Yaning Yang
The analysis of the leukemia data from Whitehead/MIT group is a discriminant analysis (also called a supervised learning). Among thousands of genes whose expression levels are meas…
DNA Segmentation as A Model Selection Process
Wentian Li
Previous divide-and-conquer segmentation analyses of DNA sequences do not provide a satisfactory stopping criterion for the recursion. This paper proposes that segmentation be cons…
