In information retrieval, efficient accomplishing the nearest neighbor search on large scale database is a great challenge. Hashing based indexing methods represent each data instance as a binary string to retrieve the approximate nearest neighbors. In this paper, we present a semi-randomized hashing approach to preserve the Euclidean distance by binary codes. Euclidean distance preserving is a classic...
Lead affects almost every system in the body and 4-aminobiphenyl increases the incidence of bladder cancer among human exposed to aromatic amines, but little attention has been paid to the effects of lead (heavy metals) on the distribution and metabolic kinetics of 4-ABP (organic pollutants) in the organisms of the terrestrial ecosystems. In this study, male S.D. rats as model animals drinking tap...
