arXiv:2601.07404v1 Announce Type: new Abstract: Many catastrophic events, including landslides, rockbursts, glacier breakoffs, and volcanic eruptions, are preceded by an observable acceleration phase that offers a critical window for early warning and hazard mitigation; however, the duration of this precursory phase re...

Extending the Biswas--Chatterjee--Sen model with nonconformists and inflexibles
arXiv:2601.07432v1 Announce Type: new Abstract: Originally, the Biswas--Chatterjee--Sen model exhibits an order/disorder phase transition for a sufficiently large number of negative interactions among actors. In this paper, the model is extended by the nonconformists and inflexibles. Nonconformists are actors who do no...
