The phrase "atomic fluctuation" is correct and usable in written English.
It can be used in scientific contexts, particularly in physics or chemistry, to describe variations in the properties of atoms or subatomic particles.
Example: "The researchers observed an atomic fluctuation that could explain the unexpected behavior of the material at low temperatures."
Alternatives: "quantum fluctuation" or "atomic variation".
To choose an appropriate force constant k, an analytic formula based on the equipartition theorem is given by Gilson et al.:(36) where ∂ r is is the atomic fluctuation of the constrained atom or center of mass of the ligand during the course of a MD simulation with the fully unperturbed potential function, R is the molar gas constant, and T = 300 K.
Bond breaking is a direct consequence of atomic fluctuation overcoming the interatomic cohesive energy, which in turn causes the disordered fluctuation of atoms.
At low strain rates, the slippage along (111) planes dominates the stretching deformation, and atomic fluctuation is in an equilibrium state.
It is shown in Figure 1 that macro-breaking position distributions of the nanowires are from the micro-atomic fluctuation of three crystallographic orientations at different strain rates and the ways of atomic fluctuation are related with deformation mechanism of the nanowires.
Strong shocks at high strain rates result in the superplastic behaviors and local melted structures, which induced atomic fluctuation in non-equilibrium state, whereas the atomic fluctuation in quasi-equilibrium state brings irregular character of the MPBP distribution at the transition area of the strain rate (II).
Moreover, we examined the atomic fluctuation of each residue by calculating the root-mean-squared fluctuation (RMSF) of backbone atoms.
The root mean square fluctuation (RMSf) analysis per residue and root mean square deviation per residue (RMSd) of the backbone atoms are used to analyze the atomic fluctuations of the predicted model of LipAMS8. Figure 5 shows the RMSd per residue at 0°C, 5°C, 25°C, 37°C, 50°C, and 100°C.
We checked that the small coefficients did not stem from extremely large thermal atomic fluctuations, which are often observed for atoms with a small number of neighbors (data not shown).
This gradual change of the third principal component is concomitant with the slow adjustment process of a near-native state into the native structure [ 17], noticed in the variation of RMSD. Figure 6 shows how the atoms contribute to the principal components, measured by the C α atomic fluctuations through the ADMD simulation.
Comparison of the protein atomic fluctuations averaged per residue in the presence/absence of the ligands in the binding site.
The GNM has been successful in predicting atomic fluctuations around an energy minimum.
