Mathematical Modeling of Pulse‐Seeded Metapopulation Dynamics for Andes Hantavirus Border Dispersal
Engineering Reports, Volume 8, Issue 9, September 2026.A pulse‐seeded metapopulation SEIR model for Andes hantavirus maritime dispersal shows that heterogeneous quarantine compliance determines secondary outbreak risk. The weakest‐compliance country governs global containment, while uniform compliance above ∼65%$$ \sim 65\% $$ reduces the global reproduction number below unity.

Bayesian Inference for Multivariate Monotone Densities
Scandinavian Journal of Statistics, Volume 53, Issue 3, Page 1206-1229, September 2026.ABSTRACT We consider a nonparametric Bayesian approach to estimation and testing for a multivariate monotone density. Instead of following the conventional Bayesian approach of imposing a prior that satisfies the monotonicity restriction, we place a prior on the step heights via binning and a Dirichlet distribution. The resulting posterior distribution

Bound on Lyapunov exponent in Kerr-Newman-de Sitter black holes by a charged particle
Journal of High Energy PhysicsWe investigate the bound on the Lyapunov exponents by a charged particle in Kerr-Newman-de Sitter black holes using analytic and numerical methods. We determine whether the Lyapunov exponent can exceed the bound by an electrically charged particle with ...

Convergence and combinatorics of the Reverse algorithm
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract We study the Reverse algorithm, a multidimensional continued fraction algorithm, which is not unimodular. We show that the Reverse algorithm is ergodic and, by proving that its second Lyapunov exponent is negative, that it is a.e. exponentially convergent.

Greenland's Topography Triggers Cyclogenesis: Synergy Between Lee Cyclogenesis and Jet Streak
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.Abstract Arctic cyclones play a crucial role in shaping Arctic weather patterns and influencing sea ice concentrations. During the Multidisciplinary Drifting Observatory for the Study of Arctic Climate expedition in April 2020, an Arctic cyclone was observed at the leeside of Greenland, prompting our hypothesis that lee cyclogenesis contributed ...
