ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Educational assessment without numbers
Psychometrics conceptualizes a person's proficiency (or ability, or competence), in a cognitive or educational domain, as a latent numerical quantity. Yet both conceptual and empirical studies have shown that the assumption of quantitative structure for ...

Design of Role Based Access Control for Triadic Concept Analysis
Formal concept analysis can be used to design access control hierarchy. There are investigations reported in the literature so far on the logic that transforms the three dimensional access control matrix into dyadic formal contexts. The transformation is

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.

In the formal concept analysis (FCA), a concept lattice represents the basic structure derived from Boolean data describing the relationships between objects and attributes. One of the basic problems of FCA is to control the structure of concept lattices

This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Description of Common Characters in Conflict Analysis via GOE-Concept Lattices
Conflicts widely exist in social problems. In order to better straight forwardly present and semantically describe conflict analysis problem, and inspired by three-way approximate concept analysis on the incomplete contexts, this paper regards a conflict

Relating generalized concept lattices and concept lattices for non-commutative conjunctors
The authors prove that any concept lattice for non-commutative fuzzy logic is isomorphic to a sublattice of the Cartesian product of two generalized concept lattices. Related theory can be found in the papers of \textit{G. Georgescu} and \textit{A. Popescu} [Fundam. Inform. 53, No.~1, 23--54 (2002; Zbl 1023.03016)] and of \textit{R.
