Virtual element approximation of eigenvalue problems: Is the stabilization of the right hand side necessary?

The VEM approximation of eigenvalue problems usually involves the appropriate tuning of stabilization parameters, unless self-stabilizing or stabilization-free VEM are used. In this paper we prove that for elliptic self-adjoint eigenvalue problems the stabilization of the mass ma...

A Survey on Cybersecurity Threats in Industrial and Information Technology Environments: Advancements and Resilience Through Network Steganographic Techniques

The complex interplay of Operational Technology (OT) and Information Technology (IT) daily supports critical infrastructures managing energy, transportation, manufacturing, and utilities. Due to their importance, the number of attacks targeting IT/OT scenarios has increased. The...
