Generating observation guided ensembles for data assimilation with denoising diffusion probabilistic model
Yuuichi Asahi, Yuta Hasegawa, Naoyuki Onodera +3
This paper presents an ensemble data assimilation method using the pseudo ensembles generated by denoising diffusion probabilistic model. Since the model is trained against noisy a…
BOTAN: BOnd TArgeting Network for prediction of slow glassy dynamics by machine learning relative motion
Hayato Shiba, Masatoshi Hanai, Toyotaro Suzumura +1
Recent developments in machine learning have enabled accurate predictions of the dynamics of slow structural relaxation in glass-forming systems. However, existing machine-learning…
Local Density Fluctuation Governs the Divergence of Viscosity underlying Elastic and Hydrodynamic Anomalies in a 2D Glass-Forming Liquid
Hayato Shiba, Takeshi Kawasaki, Kang Kim
If a liquid is cooled rapidly to form a glass, its structural relaxation becomes retarded, producing a drastic increase in viscosity. In two dimensions, strong long-wavelength fluc…
Unveiling Dimensionality Dependence of Glassy Dynamics: 2D Infinite Fluctuation Eclipses Inherent Structural Relaxation
Hayato Shiba, Yasunori Yamada, Takeshi Kawasaki +1
By using large-scale molecular dynamics simulations, the dynamics of two-dimensional (2D) supercooled liquids turns out to be dependent on the system size, while the size dependenc…
Monte Carlo study of the frame, fluctuation and internal tensions of fluctuating membranes with fixed area
Hayato Shiba, Hiroshi Noguchi, Jean-Baptiste Fournier
Three types of surface tensions can be defined for lipid membranes: the internal tension, , conjugated to the real membrane area in the Hamiltonian, the mechanical frame tension…
Mechanical properties and microdomain separation of fluid membranes with anchored polymers
Hao Wu, Hayato Shiba, Hiroshi Noguchi
The entropic effects of anchored polymers on biomembranes are studied using simulations of a meshless membrane model combined with anchored linear polymer chains. The bending rigid…
