Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Brownian dynamics simulations on the trapping characteristics of magnetic rod-like particles via multi-magnetic poles

Nihon Kikai Gakkai ronbunshu, 2022
In the present study, we have attempted to investigate a feasibility of exhibiting a significant trapping performance by means of multi-pairs of magnetic poles.

Discontinuous shear thickening in Brownian suspensions by dynamic simulation [PDF]

Proceedings of the National Academy of Sciences, 2015
Significance Colloidal shear thickening is a phenomenon by which a dense mixture (or suspension) of sub–micrometer-sized particles in a fluid becomes more viscous when strained. It has important (mostly negative) consequences as dense suspensions are found in many industrial processes. Its origin is a long-standing unsolved problem in

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

Advanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

Brownian Dynamics Simulation of Protein Solutions: Structural and Dynamical Properties [PDF]

Biophysical Journal, 2010
The study of solutions of biomacromolecules provides an important basis for understanding the behavior of many fundamental cellular processes, such as protein folding, self-assembly, biochemical reactions, and signal transduction. Here, we describe a Brownian dynamics simulation procedure and its validation for the study of the dynamic and structural ...

Ballistic Brownian motion of nanoconfined DNA [PDF]

, 2023
Theoretical treatments of polymer dynamics in liquid generally start with the basic assumption that motion at the smallest scale is heavily overdamped; therefore, inertia can be neglected.

A Fractional Heston-Type Model as a Singular Stochastic Equation Driven by Fractional Brownian Motion

Fractal and Fractional
This paper introduces the fractional Heston-type (fHt) model as a stochastic system comprising the stock price process modeled by a geometric Brownian motion. In this model, the infinitesimal return volatility is characterized by the square of a singular

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Discriminating protein tags on a dsDNA construct using a Dual Nanopore Device

Scientific Reports, 2022
We report Brownian dynamics simulation results with the specific goal to identify key parameters controlling the experimentally measurable characteristics of protein tags on a dsDNA construct translocating through a double nanopore setup.

Stokesian Dynamics simulation of Brownian suspensions [PDF]

Journal of Fluid Mechanics, 1996
The non-equilibrium behaviour of concentrated colloidal dispersions is studied by Stokesian Dynamics, a general molecular-dynamics-like technique for simulating particles suspended in a viscous fluid. The simulations are of a suspension of monodisperse Brownian hard spheres in simple shear flow as a function of the Péclet number, Pe, which measures the
