چکیده

A molecular dynamics algorithm in principal component space is presented. It is demonstrated that sampling can be improved without changing the ensemble by assigning masses to the principal components proportional to the inverse square root of the eigenvalues. The setup of the simulation requires no prior knowledge of the system; a short initial MD simulation to extract the eigenvectors and eigenvalues suffices. Independent measures indicated a 6-7 times faster sampling compared to a regular molecular dynamics simulation.

Molecular dynamics simulation and docking studies on the binding properties of several anticancer drugs to human serum albumin

Disposition and transportation of anticancer drugs by human serum albumin (HSA) affects their bioavailability, distribution and elimination. In this study, the interaction of a set of anticancer drugs with HSA was investigated by molecular dynamics and molecular docking simulations. The drugs' activities were analyzed according to their docking scores, binding sites and structural descriptors. ...

Computational Generation inhibitor-Bound Conformers of P38 Map Kinase and Comparison with Experiments

The p38 MAP kinases play a critical role in regulating stress-activated pathways, and serve as molecular targets for controlling inflammatory diseases. Computer-aided efforts for developing p38 inhibitors have been hampered by the necessity to include the enzyme conformational flexibility in ligand docking simulations. A useful strategy in such complicated cases is to perform ensemble-docking p...

An application of principal component analysis and logistic regression to facilitate production scheduling decision support system: an automotive industry case

Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...

Simulating Nanoscale Functional Motions of Biomolecules

We are describing efficient dynamics simulation methods for the characterization of functional motion of biomolecules on the nanometer scale. Multivariate statistical methods are widely used to extract and enhance functional collective motions from molecular dynamics (MD) simulations. A dimension reduction in MD is often realized through a principal component analysis or a singular value decomp...
