An Optimization of Closed Frequent Subgraph Mining Algorithm
Cybernetics and Information Technologies, 2017 Graph mining isamajor area of interest within the field of data mining in recent years. Akey aspect of graph mining is frequent subgraph mining. Central to the entire discipline of frequent subgraph mining is the concept of subgraph isomorphism.

Angewandte Chemie, EarlyView.A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

Frontiers in Psychology, 2016 We describe a Monte Carlo study examining the impact of assuming item isomorphism (i.e., equivalent construct meaning across levels of analysis) on conclusions about homology (i.e., equivalent structural relations across levels of analysis) under varying

Discrete Mathematics, 1993 This note is concerned with a question on the maximum possible \(s\) such that an arbitrary graph or hypergraph \(G\) contains a pair of edge disjoint isomorphic subgraphs of size \(s\). The authors investigate this question in the case of 3-uniform hypergraphs.

Transformation Groups, 2022 AbstractIn a 1983 paper, the author has established a (decategorified) Satake equivalence for affine Hecke algebras. In this paper, we give new proofs for some results of that paper, one based on the theory ofJ-rings and one based on the known character formula for rational representations of a reductive group in positive, large characteristic. We also

Unbiased Structure Prediction of Sophisticated Cage Structures
Angewandte Chemie, EarlyView.We introduce the software and workflow for automated, unbiased exploration of all possible connectivities of a given set of building blocks and their stoichiometry to predict stable cage structures. ABSTRACT Cage structure prediction has made significant strides by generating structures based on what the community has seen before.

The Allegory of Isomorphism [PDF]
AVANT. The Journal of the Philosophical-Interdisciplinary Vanguard, 2019 Isomorphism has become a key concept for the analysis of representation in many contexts: perceptual experience, mental imagery, scientific theories, and visual artwork may all be described as standing in isomorphisms to their targets. Yet isomorphism is a technical term from mathematics—how are we to evaluate its use in fields such as philosophy ...

ON EXTENSIONS OF PARTIAL ISOMORPHISMS [PDF]
The Journal of Symbolic Logic, 2020 AbstractIn this paper we study a notion of HL-extension (HL standing for Herwig–Lascar) for a structure in a finite relational language $\mathcal {L}$ . We give a description of all finite minimal HL-extensions of a given finite $\mathcal {L}$ -structure. In addition, we study a group-theoretic property considered by Herwig–Lascar and show that it is

Epis and monos which must be isos
International Journal of Mathematics and Mathematical Sciences, 1984 Orzech [1] has shown that every surjective endomorphism of a noetherian module is an isomorphism. Here we prove analogous results for injective endomorphisms of noetherian injective modules, and the duals of these results.

International Journal of Strategic Property Management, 2022 This paper explores the extent of organizational isomorphism (homogeneity and resemblances) in the disruption-driven investment decision-making strategies of Listed Property Trusts (LPTs) in New Zealand. Based on the tenets of institutional theory, this
