Unified Framework for Continuous and Discrete Relations of Gehring and Muckenhoupt Weights on Time Scales

open access: yesAxioms
This article contains some relations, which include some embedding and transition properties, between the Muckenhoupt classes Mγ;γ>1 and the Gehring classes Gδ;δ>1 of bi-Sobolev weights on a time scale T.

Mirror symmetry and line operators

open access: yesJournal of High Energy Physics, 2020
We study half-BPS line operators in 3d N $$ \mathcal{N} $$ = 4 gauge theories, focusing in particular on the algebras of local operators at their junctions.

Artificial neural network modelling of the neural population code underlying mathematical operations

open access: yesNeuroImage, 2023
Mathematical operations have long been regarded as a sparse, symbolic process in neuroimaging studies. In contrast, advances in artificial neural networks (ANN) have enabled extracting distributed representations of mathematical operations.

Operational operations research at the Mathematical Centre [PDF]

open access: yesEuropean Journal of Operational Research, 1984
This reprint is dedicated to Cor Baayen on the occasion of his retirement as scientific director of CWI. It was written in 1982, when CWI and NWO were still Institute MC and ZWO. Just before, the Foundation MC had confirmed its national position by becoming the ‘Netherlands Foundation for Mathematics’.

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

open access: yesAdvanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Shape invariant hypergeometric type operators with application to quantum mechanics

open access: yes, 2006
A hypergeometric type equation satisfying certain conditions defines either a finite or an infinite system of orthogonal polynomials. The associated special functions are eigenfunctions of some shape invariant operators.

A new mathematical operator

open access: yesInternational Journal of Complementary and Alternative Medicine, 2022
In mathematics the basic operations are addition, subtraction, multiplication and division, and a mathematical operator is a symbol that is used to indicate what operation is to be realized, for example, +, −, ×, ¸, and so on. In this article, I present the procedure by which it is possible to reduce any natural number -even or odd, with or without ...

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Unification modulo a partial theory of exponentiation

open access: yes, 2010
Modular exponentiation is a common mathematical operation in modern cryptography. This, along with modular multiplication at the base and exponent levels (to different moduli) plays an important role in a large number of key agreement protocols.
