This paper formulates an SEIRSHM epidemic model with general birth rate, media report and limited medical resources. Firstly, the well-posedness of solutions extinction disease are discussed. Then, existence endemic equilibrium is discussed we find when R∗ > 1 R 0 = 1, there exhibits a backward bifurcation, if < forward bifurcation. Finally, numerical simulations carried out to illustrate main results show that resources have great impact on transmission.

Abstract Synthetic aperture radar tomography (TomoSAR) has shown significant potential for the 3D Reconstruction of buildings, especially in critical areas such as topographic mapping, urban planning, and disaster monitoring. In practical applications, constraints observation trajectories frequently lead to acquisition a limited dataset sparse SAR images, presenting challenges TomoSAR affecting its signal‐to‐noise ratio elevation resolution performance. The study introduces cascade...
<p>Considering the influence of population heterogeneity, media coverage and spatial diffusion on disease transmission, this paper investigated an acquired immunodeficiency syndrome (AIDS) reaction-diffusion model with nonlinear incidence rates coverage. First, we discussed positivity boundedness system solutions. Then, basic reproduction number $ \mathcal{R}_0 was calculated, disease-free equilibrium (DFE), denoted as E^0 $, locally globally asymptotically stable when &lt; 1 $....
