Coarse-grained models of biomolecule dynamics and allostery [PDF]

, 2010
Recently, it has become increasingly accepted that thermal fluctuations take active part in functional tasks of biological molecules. We employ a set of coarse-grained models to investigate the mechanism of transmission of allosteric signal via spatial ...

Three state variables-related constitutive model for coarse-grained soil

Yantu gongcheng xuebao
The spatial variability of materials is a common problem in geotechnical engineering. For the coarse-grained soil, the essence of its spatial variability is the uneven distribution of particle gradation and density.

Enabling Scientific Workflow Sharing through Coarse-Grained Interoperability

, 2014
E-scientists want to run their scientific experiments on Distributed Computing Infrastructures (DCI) to be able to access large pools of resources and services. To run experiments on these infrastructures requires specific expertise that e-scientists may

Study on collapse behaviors of coarse grained soils

Periodica Polytechnica Civil Engineering, 2012
Collapse deformation of coarse grained materials were studied based on large scale triaxial tests, stress paths of the tests were the same as what soils actually experienced in a rock-fill dam construction, these test results showed that collapse deformation of coarse soils increased with the growth of the stress level sl and the mean stress p, thus, a

Experiment of Coefficient of Earth Pressure At-rest of Coarse-Grained Soil and Its Deformation Behavior

工程科学与技术, 2023
The coefficient of earth pressure at rest, K0, of soil is one of its important mechanical parameters, and it is of important theoretical significance and practical value to accurately determine the coefficient K0. However, it is difficult to measure this

Prediction of permeability coefficients of coarse-grained soil based on GA-BP neural network

Shuili Shuiyun Gongcheng Xuebao, 2018
In view of the obvious difference in the permeability of the coarse grained soil, effected by factors such as gradation of grain and compaction degree, a prediction method for the permeability of the coarse-grained soil is proposed in this study.

Transmembrane helix dynamics of bacterial chemoreceptors supports a piston model of signalling. [PDF]

, 2011
Transmembrane α-helices play a key role in many receptors, transmitting a signal from one side to the other of the lipid bilayer membrane. Bacterial chemoreceptors are one of the best studied such systems, with a wealth of biophysical and mutational data
