A hypercontinuous hypersmooth Schwarzschild line element transformation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
In this paper, a new derivation for one of the black hole line elements is given since the basic derivation for this line element is flawed mathematically. This derivation postulates a transformation procedure that utilizes a transformation function that

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

open access: yesAdvanced 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.

An embedding of Schwartz distributions in the algebra of asymptotic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
We present a solution of the problem of multiplication of Schwartz distributions by embedding the space of distributions into a differential algebra of generalized functions, called in the paper “asymptotic function,” similar to but different from J.

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

The Relation between the Spaces L1(F ) and L1(T) with Some Applications [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
In this research we find the relation between the nonstandard space of Lebesgue integrable functions L1(F),where F={|-N⁄2|+1,|-N⁄2|+2,…,0,…,|N⁄2| is a *finite set for N > ℕ and the space of Lebesgue integrable functions L1(T), where T=[-π,π] , with some

An Introduction to Nonstandard Analysis

open access: yesIrish Mathematical Society Bulletin, 1985
In the paper under review that author gives a brief introduction to axiomatic nonstandard analysis in the sense of Nelson's internal set theory. The author gives two examples of how to employ internal set theory in order to establish standard results.

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

open access: yesAdvanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.

Beyond Nature's Blueprint: Macrocyclic Peptides Containing Unnatural Amino Acids in Therapeutic Development

open access: yesAngewandte Chemie, EarlyView.
Strategic incorporation of unnatural amino acids transforms macrocyclic peptides into drug‐like molecules capable of engaging challenging targets. These building blocks enhance stability, permeability, and bioavailability, accelerating the development of next‐generation peptide therapeutics.

The syntax of nonstandard analysis

open access: yesAnnals of Pure and Applied Logic, 1988
The author continuous in this paper his influential study, started with the paper ``Internal set theory: a new approach to nonstandard analysis'' [Bull. Am. Math. Soc. 83, 1165-1198 (1977; Zbl 0373.02040)], of formalizations of principles of nonstandard analysis.
