Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

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.

The PRIMA Thesaurus for Materials Science and Engineering

Advanced Engineering Materials, EarlyView.
The PRIMA Thesaurus is a structured vocabulary designed to improve how materials science data is described and shared. Developed with input from multiple experts, it enables clear documentation of research workflows, data exchange, and reuse across platforms.

Involute Partner-Ruled Surfaces Formed by Involutes of Spacelike Curves in Minkowski Three-Space

Axioms
We introduced the concept of involute partner-ruled surfaces, which are formed by the involutes of spacelike curves and additional conditions ensuring the presence of definite surface normals in Minkowski three-space.

On projections of ruled and veronese surfaces

Journal of Algebra, 1989
A closed subscheme \(X\subset {\mathbb{P}}^ n\) is said to be of maximal rank if for every \(h\geq 1\) the restriction homomorphism \(H^ 0({\mathcal O}_{{\mathbb{P}}^ n}(h))\to H^ 0({\mathcal O}_ X(h))\) is injective or surjective. In many previous papers the authors gave contributions to answer the following question (Hartshorne projection conjecture).

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Ruled Surfaces with Bishop vectors via Smarandache geometry

MANAS: Journal of Engineering
The paper studies new ruled surfaces with the vectors of Bishop frame via Smarandache geometry. The fundamental forms and the corresponding curvatures are provided for each ruled surface to draw characteristics of the surfaces such as developability and ...

Classification of Some Special Types Ruled Surfaces in Simply Isotropic 3-Space

Annals of the West University of Timisoara: Mathematics and Computer Science, 2017
In this paper, we classify two types ruled surfaces in the three dimensional simply isotropic space I13 under the condition ∆xi= λixi where ∆ is the Laplace operator with respect to the first fundamental form and λ is a real number. We also give explicit

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Blaschke frames and the motion of timelike ruled surfaces in Minkowski 3-space

AIP Advances
This study explores the geometry of timelike ruled surfaces and their associated Blaschke frames in Minkowski 3-space. It establishes a mapping from spacelike differentiable curves to timelike ruled surfaces and derives the corresponding differential ...

Ruled Surfaces and Their Geometric Invariants via the Orthogonal Modified Frame in Minkowski 3-Space

Mathematics
Ruled surfaces in Minkowski 3-space play a crucial role in differential geometry and have significant applications in physics and engineering. This study explores the fundamental properties of ruled surfaces via orthogonal modified frame in Minkowski ...
