Randomly sparsified Richardson iteration: A dimension‐independent sparse linear solver
Communications on Pure and Applied Mathematics, Volume 79, Issue 1, Page 89-122, January 2026.Abstract Recently, a class of algorithms combining classical fixed‐point iterations with repeated random sparsification of approximate solution vectors has been successfully applied to eigenproblems with matrices as large as 10108×10108$10^{108} \times 10^{108}$. So far, a complete mathematical explanation for this success has proven elusive.

Optimal dividends in a discrete-time dual risk model with stochastic expenses
AIMS MathematicsDividend policies play a pivotal role in financial management by aiming to maximize shareholders' interest and effectively managing risk. In this paper, we explore the optimal dividend strategy in a discrete-time compound binomial dual risk framework ...

Food Subsidy Effects on Host Foraging Behavior Shape Host–Macroparasite Infection Dynamics
Ecology and Evolution, Volume 16, Issue 1, January 2026.Wildlife behavioral responses to different distributions of food subsidies could shape encounter and infection intensity of environmentally transmitted parasites. Using a mathematical model, we show that the way in which food subsidy changes transmission rate and variation in parasite burdens (e.g., through changes in time spent foraging and variation ...

Modeling Bounded Count Environmental Data Using a Contaminated Beta‐Binomial Regression Model
Environmetrics, Volume 37, Issue 1, January 2026.ABSTRACT Bounded count data are commonly encountered in environmental studies. This paper examines two environmental applications illustrating their relevance. The first investigates the effect of winter malnutrition on mule deer (Odocoileus hemionus) fawn mortality.

Environmetrics, Volume 37, Issue 1, January 2026.ABSTRACT Classic Bayesian methods with complex environmental models are frequently infeasible due to an intractable likelihood. Simulation‐based inference methods, such as neural posterior estimation, calculate posteriors without accessing a likelihood function by leveraging the fact that data can be quickly simulated from the model, but converge ...

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.Global climate change has intensified extreme weather events, including short‐duration but intense rainfall, which can significantly impact avian reproduction. This study examines the effects of extreme rainfall on the reproductive phenology and performance of the European roller Coracias garrulus, a single‐brooded migratory bird, in a semiarid ...
