Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Boyanov-Naydenov problem and Kolmogorov type inequalities for positive (negative) parts of functions
Researches in MathematicsWe prove that Boyanov-Naidenov problem $\|x^{(k)}_{\pm}\|_{q,\, \mu} \to \sup$ on classes of functions $\Omega^r_p(A_0, A_r):=\{x\in L^r_{\infty}: \|x^{(r)}\|_{\infty}\le A_r, L(x)_p\le A_0 \}$, where $k= 0,1,...,r-1$, $q \ge 1$ for $k\ge 1$, $q \ge p ...

Tikhonov well-posedness and differentiability on asymmetrically normed spaces
Quaestiones MathematicaeOn normed vector spaces there is a well-known connection between the Tikhonov well-posedness of a minimisation problem and the differentiability of an associated convex conjugate function. We show how this duality naturally generalises to the setting of asymmetrically normed spaces and prove a universal differentiability property of the convex ...

Advanced Engineering Materials, EarlyView.Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Advanced Engineering Materials, EarlyView.Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Bishop-Phelps Theorem for Normed Cones
پژوهشهای ریاضی, 2019 Introduction In the last few years there is a growing interest in the theory of quasi-metric spaces and other related structures such as quasi-normed cones and asymmetric normed linear spaces, because such a theory provides an important tool in the study

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.
