Biochar has been frequently used as a persulfate (PS) activator due to its attractive properties, but dissolved organic matter (DOM) derived from the non‑carbonized part of biochar has received less attention, not to mention its specific role and i

In this article, we give an algorithm for isotonic regressions on ordered rectangular grids. The running time of the algorithm is no more than cubic in the number of grid points. This algorithm makes bivariate isotonic regression a practical choice f

In this paper, weighted least absolute deviation problems (LAD) with order restrictions on a quasi-ordered finite set are considered. A well known example of these problems is to find maximum likelihood estimates for the location parameters of bilate
