In Situ TEM Imaging Reveals the Dynamic Interplay Between Attraction, Repulsion and Sequential Attraction-Repulsion in Gold Nanoparticles. [PDF]
SmallAbstract Recent efforts on manipulating metal nanoparticles (NPs) using an electron beam have offered new insights into nanoparticle behavior, structural transition, and the emergence of new properties. Despite an increasing understanding of the dynamics of electron beam‐induced coalescence of NPs, several ...

Polarization in Attraction-Repulsion Models [PDF]
2020 IEEE International Symposium on Information Theory (ISIT), 2020 This paper introduces a model for opinion dynamics, where at each time step, randomly selected agents see their opinions - modeled as scalars in [0,1] - evolve depending on a local interaction function. In the classical Bounded Confidence Model, agents opinions get attracted when they are close enough.

A free boundary problem for an attraction–repulsion chemotaxis system [PDF]
Boundary Value Problems, 2018 In this paper we study an attraction–repulsion chemotaxis system with a free boundary in one space dimension. First, under some conditions, we investigate existence, uniqueness and uniform estimates of the global solution.

Solutions of the attraction-repulsion-chemotaxis system with nonlinear diffusion
Mathematical Modelling and AnalysisIn this study, we consider the well-posedness of the attraction-repulsion chemotaxis system. This paper explores the dynamics of species movement in reaction to two chemically opposing substances, incorporating nonlinear diffusion. Our primary objective

Collective Dynamics of Swarms with a New Attraction/Repulsion Function [PDF]
Mathematical Problems in Engineering, 2011 We specify an “individual‐based” continuous‐time model for swarm aggregation in n‐dimensional Euclidean space. We show that the swarm is completely stable, and the center of the swarm is stationary. Numerical simulations indicate that the individuals will form a stable and cohesive swarm, and under the attraction/repulsion function, the bound of the ...

A class of attractions/repulsion functions for stable swarm aggregations
International Journal of Control, 2003 In this brief article, we consider an M-member 'individual-based' continuous time swarm model in an n-dimensional space and extend the results in Gazi and Passino (2003) by specifying a general class of attraction/repulsion functions that can be used to achieve swarm aggregation.

Wind power forecasting using optimized LSTM by attraction–repulsion optimization algorithm
Ain Shams Engineering JournalWind power forecasting is crucial for energy conversion and management. This study employs the long short-term memory (LSTM) network, a specialized form of recurrent neural networks (RNNs) noted for its effectiveness in time-series prediction, to predict

Convergence Rates of Attractive-Repulsive MCMC Algorithms [PDF]
Methodology and Computing in Applied Probability, 2021 We consider MCMC algorithms for certain particle systems which include both attractive and repulsive forces, making their convergence analysis challenging. We prove that a version of these algorithms on a bounded state space is uniformly ergodic with an explicit quantitative convergence rate.

Large time behavior in a quasilinear parabolic-parabolic-elliptic attraction-repulsion chemotaxis system [PDF]
, 2022 summary:This paper deals with a quasilinear parabolic-parabolic-elliptic attraction-repulsion chemotaxis system. Boundedness, stabilization and blow-up in this system of the fully parabolic and parabolic-elliptic-elliptic versions have already been ...
