Previously, research on controlling gene networks has been carried out based on a single stimulus-response of cells. More recently, studies have been proposed to precisely analyze complex gene ...

Abstract In this paper, we consider the local asymptotics of the nonparametric function in a partially linear model, within the framework of the divide-and-conquer estimation. Unlike the ...

About this issue Abstract In this study, we investigate the problem of testing the equality of two distributions by integrating the squared norm of the difference between two corresponding empirical ...

We propose a middle-ground approach we call practical finance: analytic approximations to optimal solutions as a function of relevant parameters in realistic settings that are easily computed in a ...

Cell Energy and Cell Functions Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy.

The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain.
