High Relative Accuracy With Collocation Matrices of q$$ q $$‐Jacobi Polynomials

Numerical Linear Algebra with Applications, Volume 32, Issue 1, February 2025.
ABSTRACT Little q$$ q $$‐Jacobi polynomials belong to the field of quantum calculus. This article obtains the bidiagonal decomposition of the collocation matrices of these polynomials, showing that, in many cases, it can be constructed to high relative accuracy (HRA).

Influence of Carbon Dioxide on the Phase Behavior of Pharmaceutical Drug‐Polymer Dispersions

Macromolecular Chemistry and Physics, Volume 226, Issue 2, January 2025.
Amorphous solid dispersion formulations tackle oral delivery challenges for poorly soluble drugs by embedding them in soluble carrier polymers. High‐pressure differential scanning calorimetry reveals the influence of carbon dioxide on drug‐polymer phase behavior.

Transcendental philosophy and logic diagrams

Philosophical Investigations, Volume 48, Issue 1, Page 91-117, January 2025.
Abstract Logic diagrams have seen a resurgence in their application in a range of fields, including logic, biology, media science, computer science and philosophy. Consequently, understanding the history and philosophy of these diagrams has become crucial.

Fuzzy Computational Analysis of Fuzzy Tadpole Graph

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we explore the application of fuzzy topological indices to the fuzzy tadpole graph TA,B, a hybrid structure that combines the cyclic and path‐like components within a fuzzy framework. We compute and analyze several key fuzzy indices, including the fuzzy Zagreb indices, fuzzy Randić index, fuzzy Harmonic index, fuzzy Sombor index, fuzzy ...

From 3D point‐cloud data to explainable geometric deep learning: State‐of‐the‐art and future challenges

WIREs Data Mining and Knowledge Discovery, Volume 14, Issue 6, November/December 2024.
From point‐cloud data to explainable geometric learning. Abstract We present an exciting journey from 3D point‐cloud data (PCD) to the state of the art in graph neural networks (GNNs) and their evolution with explainable artificial intelligence (XAI), and 3D geometric priors with the human‐in‐the‐loop. We follow a simple definition of a “digital twin,”

Variational approaches to the elasticity of deformable strings with and without mass redistribution

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 104, Issue 8, August 2024.
Abstract The catenary is a curve that has played a significant role in the history of mathematics, finding applications in various disciplines such as mechanics, technology, architecture, the arts, and biology. In this paper, we introduce some generalizations by applying the variational method to deformable strings.

Combination of a Viscoelastic and a Tribological Analysis of a Low‐Density Polyethylene with a High Degree of Cross‐linking

Macromolecular Chemistry and Physics, Volume 225, Issue 13, July 2024.
Cross‐linking of a low‐density polyethylene (LDPE) using dicumyl peroxide (DCP) strongly influences the crystallinity and as a consequence the tribological properties. Wear can be effectively reduced already at a low peroxide concentration of 1 phr because of the covalent network. A high peroxide concentration of 20 phr and the resulting higher contact

In Situ Alloying of Ti-6Al-7Nb with Copper Using Laser Powder Bed Fusion

Crystals
Titanium alloys are widely employed for biomedical implants due to their high strength, biocompatibility, and corrosion resistance, yet their lack of intrinsic antibacterial activity remains a major limitation.
