International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Some identities associated with degenerate harmonic and hyperharmonic numbers
Mathematical and Computer Modelling of Dynamical SystemsThe study of degenerate versions of special polynomials and numbers has seen significant progress in recent years. In this paper, we establish several identities involving degenerate harmonic and hyperharmonic numbers, which are degenerate versions of ...

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

SOME IDENTITIES FOR GENERALIZED HARMONIC NUMBERS
Matematički VesnikFor a positive real \(\alpha\) and a natural number \(n\), the generalized harmonic numbers are defined as \(H_0(\alpha)=0\) and for \(n\geq 1\), \(H_n(\alpha)= \sum_{i=1}^n \frac{1}{i\alpha^i}\). For \(r < 0\) or \(n \leq 0\), the hyperharmonic number of rank \(r\), \(H^r_n(\alpha)\) is defined as 0, \(H^0_n(\alpha)\) is defined as \(\frac{1}{n\alpha ...

Advanced Functional Materials, EarlyView.Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.
