Definition of anharmonic in English: anharmonicadjectiveanhɑːˈmɒnɪkˌænhɑrˈmɑnɪk Physics Relating to or denoting motion that is not simple harmonic. 〔物理〕非谐的 Example sentencesExamples - Rapidly rotating Bose-Einstein condensates confined in anharmonic traps can exhibit a rich variety of vortex phases.
- The anharmonic dynamics involve diffusive motion and allow sampling of different conformational substates.
- Experimental and computer simulation studies have revealed the presence of a glasslike transition in the internal dynamics of hydrated proteins at ~ 200 K involving an increase of the amplitude of anharmonic dynamics.
- In the hydrated samples a ‘glass-like’ transition leading to an anharmonic dynamics is observed.
- Some studies have found a relationship between the onset of anharmonic motion and activity of proteins.
- The existence of such a detailed structure of the [upsilon] Fe-His band shape cannot be explained by the anharmonic coupling model of Bitler and Stavrov, which at 10 K predicts only a single line.
- Our approach is next tested against computer simulations of a multimodule titin model with anharmonic linkers and then applied to experimental data for the unfolding of titin.
- Furthermore, we expect that small anharmonic corrections present in both the native and the random states will cancel out.
- Several mechanisms have been proposed to explain the large critical temperature, including a double gap structure and anharmonic effects.
- To make a rectifier, the researchers considered an anharmonic chain sandwiched between two harmonic caps, one with stiff springs - which vibrate at higher frequencies - and the other with more pliable springs.
- Motions along the first few eigenvectors are mainly large anharmonic fluctuations and generally can be linked to the biological function of proteins.
- It was successfully fitted to the anharmonic coupling model, the fitting parameters being close to those obtained earlier.
- More recently the conclusion about the presence of the anharmonic coupling between the Fe-His and Fe-P displacements has been supported experimentally as well as theoretically using quantum chemical calculations.
- The cantilever oscillation is anharmonic and asymmetric when the quality factor is low, in contrast with TM AFM in air, where the cantilever oscillation is approximately sinusoidal and symmetric.
- The nature of the biological processes driven by ATP binding and hydrolysis is, of course, highly anharmonic.
- The CO band thermal broadening stems from the anharmonic coupling with motions of the heme environment, which, in the glassy state, are frozen in.
- However, diffusive motion is present at all hydrations and temperatures studied, and the hydration-induced anharmonic motions are not required for activity.
- Such curves are not characterized by parabolic functions, indicating that hydrogen-bonding interactions are strongly anharmonic.
- It seems that this transition reflects a partial freezing of the protein, which changes from an anharmonic to a harmonic regime induced by the glass transition in the surrounding solvent.
- For an anharmonic potential, the spacing between modes changes as energy increases.
Derivativesnoun Physics The onset of the anharmonicity occurs at temperatures that increase from ~ 180 K to 260 K upon decreasing hydration from 0.5 to 0.1 g saccharide/g D 2 O. Example sentencesExamples - Other studies reveal the properties of glasses made by one particular sugar, trehalose, in reducing the anharmonicity of slow vibrational modes of embedded proteins.
- It is also of interest to examine the importance of correcting for anharmonicity with mode scanning by recomputing the binding free energies with the pure harmonic approximation.
- In addition, unlike the rigid-rotor harmonic oscillator method used in MM-PBSA, this method of calculating configuration integrals accounts for anharmonicity and has been numerically validated.
- The observed solvent coupling leads to the question of whether the dynamical transition in a solvated protein is controlled by the solvent or whether the intrinsic anharmonicity of protein dynamics also plays a role.
- The temperature dependence of the FIR absorbance suggests that the anharmonicity of the conformational potential can be quantified, and requires more thorough measurements of this temperature dependence.
