BACKGROUND The ecological risk of heavy metal anomaly in soil is widespread due to human activities and natural processes. Hg anomaly in urban soil and Cd anomaly along rivers are the typical cases. Recently, the chemical sequential extraction method

Hitherto, organochlorine pesticides (OCPs) have been reported with the highest residue level and the highest detection rate in human beings. Breast milk is the earliest biological medium used to research OCPs in humans and provides an effective way t

The new type of ideal basis introduced herein constitutes a compromise between the Gr\"obner bases based on the Buchberger's algorithm and the characteristic sets based on the Wu's method. It reduces the complexity of the traditional Gr\"obner bases

The proper basis formulated herein constitutes an improvement on the Gr\"obner basis for a zero-dimensional polynomial ideal. Let $K[\mathbf{x}]$ be a polynomial ring over a field $K$ with $\mathbf{x}:=(x_1,\dotsc,x_n)$. With $x_1$ being the least va

This paper formulates an elementary algorithm for resolution of singularities in a neighborhood of a singular point over a field of characteristic zero. The algorithm is composed of finite sequences of Newton polyhedra and monomial transformations an

This paper solves the open problem on the sharp bound for the number of isolated solutions in $\mathbf{R}_*^n$ to the real system of $n$ polynomial equations in $n$ variables, i.e., the real $n$ by $n$ fewnomial system. For an unmixed system of $n$ p
