Dmitriev A., Kornilov V., Batienkov R., Lecture Notes in Civil Engineering 2026 Vol. 886 P. 249–255

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

The effect of magnetic field dissipation in the inner heliosheath: reconciling global heliosphere model and voyager data

Sergey D. Korolkov, Igor I. Baliukin, Opher M., Advances in Space Research 2026 Vol. 77 No. 6 P. 7443–7454

However, Voyager 1 and 2 observations show only a gradual increase throughout this region. This mismatch is largely attributed to the simplified assumption of a unipolar solar ...
