In wireless sensor networks, it is common that adversaries capture some nodes to intercept, tamper, or drop valuable packages.We can employ reputation systems to identify the compromised nodes (CNs).In this paper, the areas that cover a set of dense CNs are called compromised regions (CRs) and apparently, they are a greater threat to the networks t
There is a pressing need for efficacious therapies in the field of respiratory diseases and infections.Lipid nanocarriers, administered through aerosols, represent a promising tool for maximizing therapeutic concentration in targeted cells and minimizing systemic exposure.However, this approach requires the application of efficient and safe nanomat
