Graphics processing unit accelerated coarse-grained protein-protein docking [PDF]

open access: yes, 2011
Includes abstract.Includes bibliographical references (leaves [187]-202).In this work, we describe a Graphics processing unit (GPU) implementation of the Kim-Hummer coarse-grained model for protein docking simulations, using a Replica Exchange Monte ...

Rate-dependent experimental study on unsaturated coarse-grained soil controlled by matrix suction

open access: yesYantu gongcheng xuebao, 2023
To study the time-dependent deformation characteristics of high-fill subgrade in mountainous areas, the water-retention characteristics of coarse filler and a series of rate-dependent mechanical properties tests under constant suction are carried out for

Experimental Study of the Composition and Structure of Granular Media in the Shear Bands Based on the HHC-Granular Model

open access: yesJournal of Spectroscopy, 2014
The researchers cannot control the composition and structure of coarse grained soil in the indoor experiment because the granular particles of different size have the characteristics of random distribution and no sorting.

Coarse-grained parallel transitive closure algorithm: Path decomposition technique

open access: yes, 2003
We investigate the relation between fine-grained and coarse-grained distributed computations of a class of problems related to the generic transitive closure problem (TC for short). We choose an intricate systolic algorithm for the TC problem, by Guibas,

A Martini-based coarse-grained soil organic matter model derived from atomistic simulations [PDF]

open access: yes
The significance of soil organic matter (SOM) in environmental contexts, particularly its role in pollutant adsorption, has prompted increased utilization of molecular simulations to understand microscopic interactions.

Comparison of coarse-grained and all-atom representations by explicit energy landscape explorations [PDF]

open access: yes, 2021
Computational studies of large molecular systems are often hindered by resource constraints, such as the available computational time. A common approach to reduce the computational cost is to use a coarse-grained description instead of an all-atom ...

Experimental and analytical investigation on frost heave characteristics of coarse-grained soils under closed and open systems

open access: yesFrontiers in Earth Science, 2022
Coarse-grained soil is widely used in the seasonal frozen soil region as subgrade filler. However, substantial frost heave has been observed in coarse filler in high-speed railway embankments.

Coarse-Grained Modeling Using Neural Networks Trained on Structural Data

open access: yes, 2023
We propose a method of bottom-up coarse-graining, in which interactions within a coarse-grained model are determined by an artificial neural network trained on structural data obtained from multiple atomistic simulations.

Coarse-Grained Simulations of the Nanoplastic Interaction with Soil Organic Matter

open access: yesThe Journal of Physical Chemistry B
Nanoplastics (NPs) in terrestrial ecosystems represent an emerging ecological threat, yet their molecular-level interactions with soil organic matter (SOM) remain difficult to probe experimentally. Molecular simulations can bridge this gap if they capture the relevant time and length scales. Here, we employ microsecond coarse-grained molecular dynamics
