[HTML][HTML] Multi-class oscillating systems of interacting neurons

S Ditlevsen, E Löcherbach - Stochastic Processes and their Applications, 2017 - Elsevier
We consider multi-class systems of interacting nonlinear Hawkes processes modeling
several large families of neurons and study their mean field limits. As the total number of …

Dimension reduction of noisy interacting systems

N Zagli, GA Pavliotis, V Lucarini, A Alecio - Physical Review Research, 2023 - APS
We consider a class of models describing an ensemble of identical interacting agents
subject to multiplicative noise. In the thermodynamic limit, these systems exhibit continuous …

Rhythmic behavior in a two-population mean-field Ising model

F Collet, M Formentin, D Tovazzi - Physical Review E, 2016 - APS
Many real systems composed of a large number of interacting components, as, for instance,
neural networks, may exhibit collective periodic behavior even though single components …

Exploring cooking fuel choices among Ghanaian women of reproductive age: A socio-economic analysis from a statistical mechanics perspective

Access to clean and efficient cooking fuel is crucial for promoting good health, safeguarding
the environment, and driving economic growth. Despite efforts to promote the adoption of …

The relationship between anaemia and the use of treated bed nets among pregnant and non-pregnant women in Ghana

RK Ansah, S Tackie, RA Twum, K Tawiah, RK Boadi… - Plos one, 2024 - journals.plos.org
Studies have indicated that the risk of malaria, particularly its association with anaemia in
pregnant women, increases when treated bed nets are not used. This paper utilizes a …

Emergence of oscillatory behaviors for excitable systems with noise and mean-field interaction: a slow-fast dynamics approach

E Luçon, C Poquet - Communications in Mathematical Physics, 2020 - Springer
We consider the long-time dynamics of a general class of nonlinear Fokker–Planck
equations, describing the large population behavior of mean-field interacting units. The main …

Oscillatory behavior in a model of non-Markovian mean field interacting spins

P Dai Pra, M Formentin, G Pelino - Journal of Statistical Physics, 2020 - Springer
We analyze a non-Markovian mean field interacting spin system, related to the Curie–Weiss
model. We relax the Markovianity assumption by replacing the memoryless distribution of …
