FEM-ANN-GNN modeling of MHD Darcy–Forchheimer Boger nanofluid flow with coupled heat–mass transfer in a Y-shaped hourglass cavity

Purpose This study aims to numerically investigate steady two-dimensional MHD Darcy–Forchheimer mixed convection flow of a Boger nanofluid (Cu/H2O) with coupled heat and mass transfer inside a Y-shaped hourglass cavity containing a cylindrical obstacle, incorporating thermal radi...

On the Convergence of Slow-Fast Fractional McKean–Vlasov Stochastic Systems with Multivalued Operators

This article establishes a strong averaging principle for a class of slow-fast stochastic evolution systems that incorporate both McKean–Vlasov interactions and multivalued operators within a Hilbert-space variational framework. The slow variable υ evolves according to a Caputo f...

Intelligent DDoS Attack Detection in Software-Defined Networks Using Explainable Machine Learning

The recent trend of Software-Defined Networking (SDN) has posed significant cybersecurity challenges as a result of its centralized control architecture, dynamic traffic behavior, and high programmability. Although these attributes improve network flexibility and management, they...

Multimodal behavioral fingerprinting of IoMT devices a forensic approach using network and biometric signatures

The Internet of Medical Things (IoMT) has revolutionized healthcare by enabling continuous remote patient monitoring; however, it has also introduced critical vulnerabilities where cyber-attacks can directly threaten patient safety. Traditional digital forensics as well as intrus...
