Probabilistic properties and applications of several variations of Brownian motion
Nantong Daxue xuebao. Ziran kexue ban, 2022 On the basis of standard Brownian motion, this paper discusses several kinds of variations related to standard Brownian motion in the form of probability distribution and joint distribution.

Communications in Mathematical Sciences, 2004 We consider a stochastic particle model for coagulating particles, whose free motion is Brownian, with diffusivity given by Einstein's law. We present in outline a derivation from this model of a spatially inhomogeneous version of Smoluchowski's coagulation equation.

Inverse Design of Amorphous Materials With Targeted Properties
Advanced Materials, EarlyView.AMDEN is a diffusion model framework for the inverse design of amorphous materials with targeted properties. By incorporating Hamiltonian Monte Carlo refinement into the denoising process, the framework overcomes the challenge of generating thermally relaxed disordered structures.

A group action on increasing sequences of set-indexed Brownian motions
Modern Stochastics: Theory and Applications, 2015 We prove that a square-integrable set-indexed stochastic process is a set-indexed Brownian motion if and only if its projection on all the strictly increasing continuous sequences are one-parameter G-time-changed Brownian motions.

, 2008 A classical model of Brownian motion consists of a heavy molecule submerged into a gas of light atoms in a closed container. In this work we study a 2D version of this model, where the molecule is a heavy disk of mass M and the gas is represented by just one point particle of mass m = 1, which interacts with the disk and the walls of the container via ...

Multiscale Volatility Analysis for Noisy High-Frequency Prices
Risks, 2023 We present a multiscale analysis of the volatility of intraday prices from high-frequency data. Our multiscale framework includes a fractional Brownian motion and microstructure noise as the building blocks.

Link dimensioning for fractional Brownian input [PDF]
, 2011 This paper provides a new formula for dimensioning of a link fed by fractional Brownian input. This formula is obtained based on another new approximate result for the stationary workload distribution of a queue loaded by fractional Brownian input.

Magnetic Droplet Manipulation on Open Surfaces
Advanced Materials Technologies, EarlyView.Recent advances in the manipulation of magnetic droplets demonstrate various manipulations on open surfaces, including transport, splitting, merging, and force‐controlled motion, enabled by magnetic particles and external fields. ABSTRACT Manipulation of liquids on a smaller scale enables applications in various fields, particularly diagnostics and ...
