Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials

Small Methods, EarlyView.
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

An Empirical Study on the Evaluation of Graph‐Based Strategies for Intelligent Modeling Assistants

Software: Practice and Experience, EarlyView.
ABSTRACT Context In the context of model‐driven engineering, the proliferation of intelligent modeling assistants (IMAs) has pushed the boundaries of automation, providing modelers with relevant recommendations based on incomplete modeling artifacts as primary input.

Content-Based Graph Matching System Using Graph Isomorphism and Sub Graph Isomorphism Algorithms [PDF]

, 2017
Finding graph isomorphism and sub graphisomorphism is an important problem in manyapplications which deal with data modelled asgraphs. Graphs can represent biological networksat the molecular, protein, or species level.

Toward an Intermediate Structural Representation of Organization in Complex Systems

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Organization is widely recognized as a fundamental concept in complex systems science, yet it rarely appears as an explicit object of scientific representation. Existing approaches successfully represent components, interactions, mechanisms, dynamical states, networks, or functions, but organizational properties are generally inferred from ...

Algorithm and Experiments in Testing Planar Graphs for Isomorphism

Journal of Graph Algorithms and Applications, 2004
We give an algorithm for isomorphism testing of planar graphs suitable for practical implementation. The algorithm is based on the decomposition of a graph into biconnected components and further into SPQR-trees.

Generating Compressed Counterfactual Hard Negative Samples for Graph Contrastive Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Graph contrastive learning (GCL) relies on acquiring high‐quality positive and negative samples to learn the structural semantics of the input graph. Previous approaches typically sampled negative samples from the same training batch or an irrelevant external graph.

On the isomorphism testing of graphs

, 2016
Graph Isomorphism is one of the very few classical problems in NP of unsettled complexity status. The families of highly regular structures, for example Steiner 2-designs, strongly regular graphs and primitive coherent configurations, have been perceived as difficult cases for graph isomorphism.

Quantum isomorphism of 2-graphs

International Journal of Mathematics
We formulate a notion of the quantum automorphism group of a [Formula: see text]-graph. After some preliminary computations, we define quantum isomorphism between a pair of [Formula: see text]-graphs. We produce a “nontrivial” example of a pair of [Formula: see text]-graphs that are not quantum isomorphic to each other.

Urban inequalities and marginalization of the Social and Solidarity Economy: A comparative analysis in the Sants‐Montjuïc district in Barcelona

Annals of Public and Cooperative Economics, EarlyView.
Abstract This article examines how urban inequalities influence the Social and Solidarity Economy (SSE) through a study of two Barcelona neighbourhoods. It evaluates the limitations of SSE promotion policies implemented between 2016 and 2024, focusing on their impact on diversifying socio‐enterprise initiatives and fostering cooperative ecosystems with
