Most of the analyses concerning signed networks have focused on balance theory, hence identifying frustration with undirected, triadic motifs having an odd number of negative edges; much less attention has been paid to their directed counte...
Diffusion crossover between q statistics and Boltzmann-Gibbs statistics in the classical inertial α-XY ferromagnet [0.03%]

We study the angular diffusion in a classical d-dimensional inertial XY model with interactions decaying with the distance between spins as r^{-α}, with α⩾0. After a very short-time ballistic regime, with σ_{θ}^{2}∼t^{2}, a superdiffu...

Active particles are self-propelled microswimmers with potential applications in biomedicine and microfluidics. With recent advances in manufacturing technology, it is now possible to experimentally realize soft and flexible artificial micr...
Energy-momentum-conserving stochastic differential equations and algorithms for the nonlinear Landau-Fokker-Planck equation [0.03%]

Coulomb collision is a fundamental diffusion process in plasmas that can be described by the Landau-Fokker-Planck (LFP) equation or the stochastic differential equation (SDE). While energy and momentum are conserved exactly in the LFP equat...
Stark effect at high electric fields and Stark ion broadening widths and shifts for different microfield distributions at quasistatic approximation in atomic oxygen spectra [0.03%]

Studies of the static Stark effect are reported for the multiplets at 615.8, 645.6, 777.6, 822.4, 844.9, and 926.5 nm (vacuum wavelengths) of atomic oxygen, which are important for various applications. From the Stark patterns recorded at v...
Forecasting and decisions in the birth-death-suppression Markov model for wildfires [0.03%]

As changing climates transform the landscape of wildfire management and suppression, agencies are faced with difficult resource allocation decisions. We analyze tradeoffs in temporal resource allocation using a simple but robust Markov mode...
Second-law violating events are not rare in nonequilibrium nonsteady states [0.03%]

For nonequilibrium systems in which fluctuations are important, it is well established that there can be events that violate the second law of thermodynamics on the trajectory level. For nonequilibrium steady-states, these second-law violat...

Detection of phase transitions is a critical task in statistical physics, traditionally pursued through analytic methods and direct numerical simulations. Recently, machine-learning techniques have emerged as promising tools in this context...

In this paper we explore the significance of nonextensive terms in Massieu functions. Finite-size effects are in many cases dominated by a term proportional to the surface area. Nevertheless, in numerical simulations of finite systems with ...

The kinetics of biological motors such as kinesin or dynein is notably influenced by a viscoelastic intracellular environment. The characteristic relaxation time of the cytosol is not separable from the colloidal timescale and therefore the...
