In this paper, we consider a stochastic heroin epidemic model with distributed delay. We analyze the model in detail: We prove the existence and uniqueness of the global positive solution of the system, the asymptotic behavior around the equilibrium point E 0 $$ {E}_0 $$ of the deterministic system, the stochastically ultimate boundedness, and the persistence in the mean of the disease.

1. IntroductionThe increasing impact of climate change, alongside the expanding demand for exploitation in the polar regions, has elevated polar navigation to a global concern. As the significance of polar regions grows, these areas are emerging as focal points for global governance, maritime routes, and resource exploration [1,2]. The polar regions are not only abundant in natural resources but also hold strategic geopolitical significance.

AbstractPlasma spray-physical vapor deposition (PS-PVD) is a promising third-generation thermal barrier coatings (TBCs) technique. Feather-like columnar TBCs with excellent strain tolerance and low thermal conductivity can be achieved using PS-PVD. However, molten CMAS (CaO–MgO–Al2O3–SiO2) can penetrate coatings and accelerate PS-PVD TBCs failure due to the feather-like columnar structure. Hence, a strategy is proposed to alleviate molten CMAS corrosion.

Rescuing Zinc Anode-Electrolyte Interface: Mechanisms, Theoretical Simulations and in-situ Characterizations
The research interest in aqueous zinc-ion batteries (AZIBs) has been surging due to the advantages of safety, abundance, and high electrochemical performance. However, some technique issues, such as dendrites, hydrogen evolution reaction side reaction, corrosion, etc. severely prohibit the development of AZIBs in practical utilizations.
