Self-organized criticality is a dynamical system property where, without external tuning, a system naturally evolves towards its critical state, characterized by scale-invariant patterns and power-law distributions. In this paper, we explor...
Estimating the population-level effects of nonpharmaceutical interventions when transmission rates of COVID-19 vary by orders of magnitude from one contact to another [0.03%]

Statistical physicists have long studied systems where the variable of interest spans many orders of magnitude, the classic example is the relaxation times of glassy materials, which are often found to follow power laws. A power-law depende...

Field-theoretical calculations predict that, at the upper critical dimension d_{c}=4, the finite-size scaling (FSS) behaviors of the Ising model would be modified by multiplicative logarithmic corrections with thermal and magnetic correctio...

Two-dimensional lattice Boltzmann (LB) models for the Shakhov kinetic equation are developed. In contrast to several previous thermal LB models with variable Prandtl number, the present approach deals with the models on Cartesian lattices. ...

The duration of the quasistationary states (QSSs) emerging in the d-dimensional classical inertial α-Heisenberg model, i.e., N three-dimensional rotators whose interactions decay with distance r_{ij} as 1/r_{ij}^{α} (α≥0), is studied th...

We study the viscoelastic relaxation dynamics of scale-free copolymer networks in the generalized Gaussian structures framework. We focus on the real and imaginary components of the complex dynamic modulus G^{*}(ω): the storage and loss mo...

We derive exact results for the critical Casimir force (CCF) within the Nagle-Kardar model with periodic boundary conditions (PBCs). The model represents a one-dimensional Ising chain with long-range equivalent-neighbor ferromagnetic intera...

In this paper, we examine the interplay between the lobby size q in the q-neighbor Ising model of opinion formation [Phys. Rev. E 92, 052105 (2015)1539-375510.1103/PhysRevE.92.052105] and the level of overlap v of two fully connected graphs...

This paper introduces a method to estimate irreversibility in multivariate time series based on the well-known mapping to a binary classification problem. Our approach utilizes gradient boosting as a binary classifier, thus providing a mode...

There is a wide range of mathematical models that describe populations of large numbers of neurons. In this article, we focus on nonlinear noisy leaky integrate-and-fire (NNLIF) models that describe neuronal activity at the level of the mem...
