Nature inspires us to address the most contemporary scientific challenges. Advances in the drug delivery system at the nano/micro-scale hold promise to treat some fatal diseases in the next few decades. Scientists have discovered that the biomolecule Chlorotoxin, a naturally occurring biomaterial, can target tumor cells in the human brain with great precision. The application of Chlorotoxin can...

How the results obtained by computer simulation of molecular systems can be validated is considered. The overall quality of the simulated properties of a molecular system will depend on ~i! the quality of the theory or model, ~ii! the accuracy of the interatomic interaction function or force field, ~iii! the degree of sampling, statistics and convergence reached in the simulation, ~iv! the qual...

In this paper, we present a compression framework, for molecular dynamics (MD) simulation data, which yields significant performance by combining the strength of principal component analysis (PCA) and discrete cosine transform (DCT). Though it is a lossy compression technique, the effect on analytics performed on decompressed data is very minimal. Compression ratio up to 13 is achieved with acc...

Molecular simulations with a large number of atoms (> 10e6) and time steps (> 10e6) require a tremendous amount of computational power, which can be provided by highly parallel machines only. This paper presents the results of our research in that area, focussing on the algorithmic aspects and the possibilities to increase the efficiency of the simulation. We identified the division of the simu...

a new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. mathematical correlations and the kinetics used in this ...

ABSTRACT: Quantitative structure-activity relationship (QSAR) study on the piperidone-grafted mono- and bis-spirooxindole-hexahydropyrrolizines as potent butyrylcholinestrase (BuChE) inhibitors were carried out using statistical methods, molecular dynamics and molecular docking simulation. QSAR methodologies, including classification and regression tree (CART), multiple linear regression (MLR),...

we have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming lennard-jones interatomic pair potential. calculations are performed by dap parallel computer. the results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. it is shown that all the main features of the bulk phase transitions are essen...
