BACKGROUND Target identification is important for modern drug discovery. With the advances in the development of molecular docking, potential binding proteins may be discovered by docking a small molecule to a repository of proteins with three-dimensional (3D) structures. To complete this task, a reverse docking program and a drug target database with 3D(More)
TarFisDock is a web-based tool for automating the procedure of searching for small molecule-protein interactions over a large repertoire of protein structures. It offers PDTD (potential drug target database), a target database containing 698 protein structures covering 15 therapeutic areas and a reverse ligand-protein docking program. In contrast to(More)
An improved potential mean force (PMF) scoring function, named KScore, has been developed by using 23 redefined ligand atom types and 17 protein atom types, as well as 28 newly introduced atom types for nucleic acids (DNA and RNA). Metal ions and water molecules embedded in the binding sites of receptors are considered explicitly by two newly defined atom(More)
A new optimization model of molecular docking is proposed, and a fast flexible docking method based on an improved adaptive genetic algorithm is developed in this paper. The algorithm takes some advanced techniques, such as multi-population genetic strategy, entropy-based searching technique with self-adaptation and the quasi-exact penalty. A new iteration(More)
BACKGROUND Development of a fast and accurate scoring function in virtual screening remains a hot issue in current computer-aided drug research. Different scoring functions focus on diverse aspects of ligand binding, and no single scoring can satisfy the peculiarities of each target system. Therefore, the idea of a consensus score strategy was put forward.(More)
Reliability allocation is the key issue of reliability designing. CNC machine is a complex product. There are many influence factors of reliability allocation. A part of them cannot be accurately measured but be evaluated by the experts. Therefore it's difficult for reliability allocation. In this paper, we consider a variety of criteria for conducting(More)
As a main method of structure-based virtual screening, molecular docking is the most widely used in practice. However, the non-ideal efficacy of scoring functions is thought as the biggest barrier which hinders the improvement of the molecular docking method. A new multi-objective strategy for molecular docking, named as MoDock, is presented to further(More)
In view of the influence of uncertain situations on Unmanned Surface Vehicle (USV) autonomous navigation, an approach to evaluate USV autonomy level based on multi-attribute decision making theory is presented. The method is to build evaluation model by giving a problem description of decision and supplying objects design. Using the model to construct a(More)
