This paper addresses the dynamic neural networks (DNNs) based resilient leader-following consensus control of multi-agent systems (MASs) under unidentified false data injection (FDI) attacks. We have examined generic linear leader-following agents in the context of stochastic FDI attacks on the network topology. When information is sent from one agent to another, it is altered as a result of the attacks.

Two-dimensional (2D) materials with intrinsic antiferromagnetic (AFM) order provide a unique avenue to harness both charge and spin degrees of freedom for practical spintronics applications. Here, by using ab initio electronic structure calculations, the interplay of discrete crystal symmetries (such as inversion ( ), time-reversal ( ), or combined symmetry) of 2D semiconducting AFM manganese selenide (MnSe) and external electric field along with graphene proximity is investigated. We show that both an external electric field and graphene proximity can independently break otherwise conserved combined symmetry in 2D MnSe, resulting in large and tunable spin-splittings in both valence and conduction bands, and provide electrical control over a wide energy range.

This study investigates the erosion behavior of Al-SiC and Al-WC metal-based composites in a solid particle impingement environment developed through powder metallurgy. Micro-sized powders of SiC and WC were utilized in different weight proportions (0-10 wt%) for fabricating the composite samples. The angle of impingements of 30-90° and impact velocity of 30-90 m/s were used for solid particle erosion testing.

After natural disasters such as earthquakes, floods, or wars occur, cellular communication networks often sustain significant damage or become impaired. In these critical situations, first responders must coordinate with other rescue teams to communicate essential information to central command and survivors. To address this challenge, we have developed a reliable and rapidly deployable wireless ad hoc system for post-disaster management using Data Distribution Service (DDS) middleware, specifically RTI-DDS, named R-RDSP.

We have studied the interfacial properties of Zn vs selected transition metal cations such as Fe, Cu, and Cr in a water-ethanol mixture using field-induced droplet ionization. This was in particular inspired by the specific surface activity of Zn that has been observed on several occasions and a desire to clarify the root cause for this behavior. We have found that Zn, due to its unique electronic configuration and atomic size, is the only ion of those under study that gives rise to specific speciation at the air-liquid interface with three ethanol molecules attached to the central atom for optimal polarity.
