Historical records, distributions and sources of mercury and zinc in sediments of East China sea: Implication from stable isotopic compositions.
The distribution and source of mercury (Hg) and zinc (Zn) in surface sediments from East China Sea (ECS) were studied using stable isotopes. Hg concentrations in surface sediments varied from 12.6 toExpand

Sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix and its applications
In this paper, we obtain the sharp upper and lower bounds for the spectral radius of a nonnegative irreducible matrix. We also apply these bounds to various matrices associated with a graph or aExpand
