Using a newly developed algorithm, MotEvo, on a combination of comprehensive ChIP-on-chip binding data, the genomes of 5 related species of yeast, and a collection of experimentally known binding sites we have produced an extensive genome-wide annotation of regulatory sites in the yeast genome containing over 12, 000 high confidence binding sites for 72 regulatory factors. Here we study the lar...

To improve e-ciency of compressed image retrieval, we propose a novel statistical feature extraction algorithm in this paper to characterize the image content directly in its compressed domain. The statistical feature extracted is mainly through computing a set of moments directly from DCT coe-cients without involving full decompression or inverse DCT. Following the algorithm design, a content-...

We present a preliminary study of the dependence of the fractal features of the soil motion due to seismic noise on the near-surface geology in the frequency range from 1 Hz to ∼ 40 Hz. In detail, we have investigated the 3-d average squared soil displacement 〈r〉 and the distribution function of the displacement fluctuations in different geological sites. The anomalous scaling of the average sq...
