Structural balance and evolution of cooperation in a population with hybrid interactions.

This study explores the evolution of cooperation in populations with mixed pairwise and three-body interactions, investigating the impact of higher-order interaction density ρ and individual interaction preference α. Our results reveal that sparse higher-order interactions markedly boost cooperation, exhibiting two critical phase transitions as ρ changes. These transitions underscore the delicate equilibrium needed for optimal cooperation, as excessive higher-order interactions can diminish returns.

Forecasting CO emissions in BRICS countries using the grey breakpoint prediction models.

In this paper, three novel grey breakpoint prediction models are proposed based on calculating the development coefficient and grey action of grey prediction models after fuzzy breakpoints, unifying the calculation methods for parameter estimation and the relevant time-response equations, and using the particle swarm optimisation algorithm to optimise the two-stage background values. Finally, the novel grey breakpoint prediction models are used to simulate and forecast the CO emissions in BRICS countries. We can see that by setting time breakpoints and fuzzy breakpoint intervals, the novel methods successfully detect abrupt changes in the system and achieve accurate predictions, thus improving the accuracy and applicability of the grey model.

Quantifying the most probable dynamics of a particle inside a sphere.

Particle random walk phenomena manifest across diverse biophysical and physical systems. Motivated by receptor diffusion dynamics toward cellular membranes, this study investigates statistically dominant transition dynamics for particles undergoing confined diffusion within spherical geometries. We developed a computational framework combining stochastic process modeling with deep learning techniques to quantify two critical aspects of the diffusion process: most probable transition time for particles migrating from the spherical center to arbitrary boundary points, and most probable transition pathways connecting the central source to preferential terminal locations on the spherical surface.
