Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture
Advanced Engineering Materials, EarlyView.Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

A unified proof of the Howe-Moore property [PDF]
, 2014 We provide a unified proof of all known examples of locally compact groups that enjoy the Howe-Moore property, namely, the vanishing at infinity of all matrix coefficients of the group unitary representations that are without non-zero invariant vectors ...

On groups of smooth maps into a simple compact Lie group
Commentarii Mathematici Helvetici, 1988 Let \(M_ 0G\) be the identity component of the group of smooth maps from a compact manifold X to a compact simple Lie group G. The diffeomorphisms of X act as automorphisms of \(M_ 0G\); another obvious class of automorphisms of \(M_ 0G\) is given by the smooth maps \(X\to Aut(G)\). The main result of this paper is that every automorphism of \(M_ 0G\),

A Simple Expression for the Casimir Operator on a Lie Group [PDF]
Proceedings of the American Mathematical Society, 1979 The expression for the Casimir operator for a real semisimple Lie group G in terms of coordinates given by the Iwasawa decomposition G = K A N G = KAN reduces on G/N to the difference of an elliptic operator with constant coefficients on A and an invariant operator on M.

Advanced Engineering Materials, EarlyView.Phase diagrams of transition‐metal di‐pnictides have been efficiently and quickly explored by combinatorial deposition of transition‐metal films and subsequent antimonization enabling the study of compounds with volatile elements. In (Fe,Ni)Sb2 and the (Fe,Cr)Sb2 substitution series, phase separation has been evidenced between class‐A and B marcasites ...

η and λ deformations as E-models
Nuclear Physics B, 2015 We show that the so-called λ deformed σ-model as well as the η deformed one belong to a class of the E-models introduced in the context of the Poisson–Lie-T-duality. The λ and η theories differ solely by the choice of the Drinfeld double; for the λ model
