Design and Detection of Covert Man-in-the-Middle Cyberattacks on Water Treatment Plants
Victor Mattos, João Henrique Schmidt, Amit Bhaya +3
Cyberattacks targeting critical infrastructures, such as water treatment facilities, represent significant threats to public health, safety, and the environment. This paper introdu…
Predicting MOOCs Dropout Using Only Two Easily Obtainable Features from the First Week's Activities
Ahmed Alamri, Mohammad Alshehri, Alexandra I. Cristea +4
While Massive Open Online Course (MOOCs) platforms provide knowledge in a new and unique way, the very high number of dropouts is a significant drawback. Several features are consi…
On existence and nonexistence of isoperimetric inequality with differents monomial weights

Four-manifolds with positive curvature
R. Diógenes, E. Ribeiro, E. Rufino
In this note we prove that a four-dimensional compact oriented half-confor\-mally flat Riemannian manifold is topologically or pr…
Spin-1/2 anisotropic Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interaction via mean-field approximation
Walter E. F. Parente, J. T. M. Pacobahyba, Minos A. Neto +2
The spin-1/2 anisotropic Heisenberg model with antiferromagnetic exchange interactions in the presence of a external magnetic field and a Dzyaloshinskii-Moriya interaction is studi…
