Topological indices are essential for encoding molecular information and have traditionally focused on the properties of individual atoms and their connections. In this work, we study and analyze the first and second entire Zagreb indices. We explore their predictive power through rigorous analysis of octane isomers and benzenoid hydrocarbons ...

Role of Intersections in Fracture Connectivity
Abstract Networks of intersecting fractures often provide the flow paths through subsurface reservoirs. Assessing network connectivity is challenging because fracture intersections compose a vanishingly small fraction of the network void volume. In this paper, motivated by 3D X‐ray imaging of the simplest element of fracture network, that is, two ...

Connected generalised Sierpiński carpets [PDF]
Generalised Sierpiński carpets are planar sets that generalise the well-known Sierpiński carpet and are defined by means of sequences of patterns. We present necessary and sufficient conditions, under which generalised Sierpiński carpets are connected ...

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

A lower bound on volumes of end‐periodic mapping tori
Abstract We provide a lower bound on the volume of the compactified mapping torus of a strongly irreducible end‐periodic homeomorphism f:S→S$f: S \rightarrow S$. This result, together with work of Field, Kim, Leininger, and Loving [J. Topol. 16 (2023), no.

Graphical models for topological groups: A case study on countable Stone spaces
Abstract By analogy with the Cayley graph of a group with respect to a finite generating set or the Cayley–Abels graph of a totally disconnected, locally compact group, we detail countable connected graphs associated to Polish groups that we term Cayley–Abels–Rosendal graphs.

Fractal Scaling of Explosively Driven Product Gases
The expanding interface between explosive product gases and ambient air is characterized as a function of time by the fractal dimension of the interface which is extracted from high‐speed image sequences. The interface is observed to increase in fractal dimension, and thus complexity, as time from detonation progresses.

Learning Image Fractals Using Chaotic Differentiable Point Splatting
Abstract Fractal geometry, defined by self‐similar patterns across scales, is crucial for understanding natural structures. This work addresses the fractal inverse problem, which involves extracting fractal codes from images to explain these patterns and synthesize them at arbitrary finer scales.

Adel verpflichtet! Das Edelgas Argon kann für die Synthese von Kohlenstoff‐Schwefel‐Kohlenstoff Thioether‐basierten Nanostrukturen auf inerten Oberflächen wie beispielsweise Graphit eingesetzt werden. Im Gegensatz zur Oberflächensynthese auf Metallen könnte dieser Ansatz die Erforschung von Feldeffekt‐Bauelementen ermöglichen.
