Molecular Dynamics Simulation of Organic Solvents

With the GB-EMP parameters we then carried out molecular dynamics simulations (MDS) for CHCl 3 and tetrahydrofuran (THF) based on the coarse- grained (CG) model. Compared with the all-atom model, the CG model can reproduce the simulation results on the whole, but there are some deviations in the simulations in some details.

[2007.11412] Coarse Graining Molecular Dynamics with

2020/7/22Coarse graining enables the investigation of molecular dynamics for larger systems and at longer timescales than is possible at atomic resolution. However, a coarse graining model must be formulated such that the conclusions we draw from it are consistent with the conclusions we would draw from a model at a finer level of detail. It has been proven that a force matching scheme defines a

Abstract: Modeling the Self

2015/11/11Coarse-grained molecular dynamics (CGMD) simulations were employed to detect key agglomeration events and calculate the corresponding rate constants. The kMC simulations employ these estimated rate constants in a stochastic framework to track the growth of the agglomerates over longer time scales and length scales.

2016/3/17Gay-Berne (GB) potential is regarded as an accurate model in the simulation of anisotropic particles, especially for liquid crystal (LC) mesogens. However, its computational complexity leads to an extremely time-consuming process for large systems. Here, we developed a GPU-accelerated molecular dynamics (MD) simulation with coarse-grained GB potential implemented in GALAMOST package to

We have constructed a coarse-grained model of crystalline cellulose to be used in molecular dynamics simulations. Using cellobiose from the recently published MARTINI coarse-grained force field for carbohydrates [Lopez, C. A. et al. J. Chem.

SimRNA: a coarse

In SimRNA, RNA molecules are represented by a coarse-grained model that facilitates the handling of non-bonding base–base interactions (Figure 1). The backbone structure is approximated by two pseudoatoms positioned at P and C4' to represent the phosphate and sugar moieties, respectively.

A solvent-free coarse-grained molecular dynamics (CGMD) model has been developed and it represents a single hemoglobin fiber with four tightly bonded chains, each of which comprises soft particles. A harmonic spring potential, a bending potential, a torsional potential, and a Lennard-Jones potential are introduced along with a Langevin thermostat to simulate the behavior of a polymerized

2015/12/14Coarse-Grained (CG) molecular dynamics (MD) simulations have become an important tool to study the insertion and dynamic behavior of membrane proteins in lipid membranes. Generally, the membrane models used in MD simulations to study membrane properties [ 1, 2 ], lipid rafts [ 3 ], membrane fusion [ 4 ], protein insertions and lipid-protein interactions [ 5 ] consist of only one- or two

Learning to Model G

G-quadruplexes have raised considerable interest during the past years for the development of therapies against cancer. These noncanonical structures of DNA may be found in telomeres and/or oncogene promoters, and it has been observed that the stabilization of such G-quadruplexes may disturb tumor cell growth. Nevertheless, the mechanisms leading to folding and stabilization of these G

Machine Learning of coarse

The aim is to learn a coarse-grained energy function U (x; θ) that will be used in conjunction with a dynamical model, e.g., Langevin dynamics, to simulate the CG molecule. θ are the parameters of the coarse-grained model – in classical CG approaches these are parameters of the potential energy function, such as force constants and partial charges, while here they denote the weights of the

We present a two-component coarse-grained molecular-dynamics model for simulating the erythrocyte membrane. The proposed model possesses the key feature of combing the lipid bilayer and the erythrocyte cytoskeleton, thus showing both the fluidic behavior of the lipid bilayer and the elastic properties of the erythrocyte cytoskeleton. In this model, three types of coarse-grained particles are
