Boundary-Layer Analysis of Repelling Particles Pushed to an Impenetrable Barrier [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2021
This paper considers the equilibrium positions of n particles in one dimension. Two forces act on the particles; a nonlocal repulsive particle-interaction force and an external force which pushes them to an impenetrable barrier. While the continuum limit

Direct proof of unconditional asymptotic consensus in the Hegselmann–Krause model with transmission‐type delay

open access: yesBulletin of the London Mathematical Society, Volume 53, Issue 5, Page 1312-1323, October 2021., 2021
Abstract We present a direct proof of asymptotic consensus in the non‐linear Hegselmann–Krause model with transmission‐type delay, where the communication weights depend on the particle distance in phase space. Our approach is based on an explicit estimate of the shrinkage of the group diameter on finite time intervals and avoids the usage of Lyapunov ...

Reproducibility of serum testing for environmental allergen‐specific IgE in dogs in Europe

open access: yesVeterinary Dermatology, Volume 32, Issue 3, Page 251-e67, June 2021., 2021
Background – Serum testing for allergen‐specific immunoglobulin (Ig)E is commonly employed to identify allergens used for allergen‐specific immunotherapy in dogs, yet the reliability of results has been a matter of debate. Objective – The aim of this study was to evaluate the reproducibility of serum tests for environmental allergen‐specific IgE in ...

Stochastic ranking process with time dependent intensities [PDF]

open access: yes, 2010
We consider the stochastic ranking process with space-time dependent jump rates for the particles. The process is a simplified model of the time evolution of the rankings such as sales ranks at online bookstores.

Emergent behaviours of a non-abelian quantum synchronisation model over the unitary group

open access: yesEuropean Journal of Applied Mathematics
We introduce a new non-abelian quantum synchronisation model over the unitary group, represented as a gradient flow, where state matrices asymptotically converge to a common one up to phase translation.

Uniform propagation of chaos for a dollar exchange econophysics model

open access: yesEuropean Journal of Applied Mathematics
We study the poor-biased model for money exchange introduced in Cao & Motsch ((2023) Kinet. Relat. Models 16(5), 764–794.): agents are being randomly picked at a rate proportional to their current wealth, and then the selected agent gives a dollar to ...

Network-based kinetic models: Emergence of a statistical description of the graph topology

open access: yesEuropean Journal of Applied Mathematics
In this paper, we propose a novel approach that employs kinetic equations to describe the collective dynamics emerging from graph-mediated pairwise interactions in multi-agent systems.

Macroscopic limit of a Fokker-Planck model of swarming rigid bodies

open access: yesEuropean Journal of Applied Mathematics
We consider self-propelled rigid bodies interacting through local body-attitude alignment modelled by stochastic differential equations. We derive a hydrodynamic model of this system at large spatio-temporal scales and particle numbers in any dimension
