Diffusion coefficients of cube-like particles for application to Brownian dynamics simulations

Nihon Kikai Gakkai ronbunshu, 2019
In the present study, we have analyzed the flow field around a cube in a Stokes flow regime in order to estimate the diffusion coefficients of cube-like particles that are required for performing Brownian dynamics simulations of a cubic particle ...

Methodological guidelines for the characterization of polysaccharide helical structures

Food Biomacromolecules, EarlyView.
Abstract Polysaccharide chain conformation is a critical determinant of their physicochemical and biological properties; however, reliable identification remains a significant challenge due to the inconsistent structural evidence yielded by conventional analytical techniques.

Planar aggregation and the coalescing Brownian flow. [PDF]

, 2008
We study a scaling limit associated to a model of planar aggregation. The model is obtained by composing certain independent random conformal maps. The evolution of harmonic measure on the boundary of the cluster is shown to converge to the coalescing ...

Bayesian Multivariate Two‐Stage Volatility‐Return Models (MTS‐VR)

Journal of Forecasting, EarlyView.
ABSTRACT This paper develops a class of models to capture the joint dynamics of asset returns and multivariate volatility. Owing to its two‐stage construction, this class is referred to as the multivariate two‐stage volatility‐return (MTS‐VR) model.

Consistent finite-element approach to Brownian polymer dynamics with anisotropic friction

, 2010
In the last decades simulation tools for Brownian dynamics of polymers have attracted more and more interest. Here we present a mathematically consistent finite element approach to the simulation of Brownian polymer dynamics.

Alternative Data for Realised Volatility Forecasting: Limit Order Book and News Stories

International Journal of Finance &Economics, EarlyView.
ABSTRACT We examine whether two major alternative data sources, limit order book information and firm‐specific news, provide incremental predictive information for daily realised volatility forecasting within the HAR‐family, using a parsimonious framework to ensure practical implementation and comparability. The framework is designed for practical real‐

Diffusion MRI‐Based Fetal Thermometry Using Cerebrospinal Fluid: A Translational Feasibility Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive fetal temperature assessment could improve MRI safety monitoring and provide insight into fetal physiology. Diffusion MRI is a potential approach because water diffusivity in free fluids is temperature dependent. However, the applicability of adult‐derived diffusivity–temperature calibration to neonatal and fetal CSF ...

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

A numerical study of the effect of graphene nanoparticle size on brownian displacement, thermophoresis, and thermal performance of graphene/water nanofluid by molecular dynamics simulation

International Journal of Thermofluids
Brownian motion, often known as BM, is an inherent characteristic of minute particles suspended in a fluid. It plays an important role in several physical and chemical processes. Thermophoresis refers to the process where particles in a fluid are carried

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...
