Topology‐based Visual Analysis of Hydrothermal Plumes
Computer Graphics Forum, EarlyView.Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Geometry‐Aware Alignment and Comparison of Hierarchical Morse Complexes with Applications
Computer Graphics Forum, EarlyView.Abstract Scalar fields derived from 3D X‐ray CT scans of samples undergoing ex situ processes, such as thermal aging, chemical etching, or mechanical stress, pose unique challenges for characterizing similarities and differences across acquisitions. Typically, a sample A (source) is imaged, removed, and subjected to experimental conditions that alter ...

Exchange energy and potential using the Laplacian of the density
, 2012 The challenge of density functional theory is the useful approximation of the exchange - correlation energy. This energy can be approximated with the local electron density and the gradient of the density.

Computer Graphics Forum, EarlyView.Abstract Network visualization has traditionally relied on heuristic metrics, such as stress, under the assumption that optimizing them leads to aesthetic and informative layouts. However, no single metric consistently produces the most effective results.

Laplacian energy of directed graphs and minimizing maximum outdegree algorithms
Energy has been studied in mathematical perspective as well as physical perspective for several years ago. In spectral graph theory, the eigenvalues of several kinds of matrices have been studied, of which Laplacian matrix attracted the greatest ...

Measuring Frame Evolution: Smoothed Temporal Framing Trajectories in Complex Policy Debates
JCMS: Journal of Common Market Studies, EarlyView.Abstract The European Union faces long‐term governance challenges in contested domains, such as migration management, health data sharing, and facial recognition technology. Across these fields, political debates are shaped by shifting ways in which actors frame problems and solutions. Understanding how such framing contests evolve over time is crucial

Journal of Time Series Analysis, EarlyView.ABSTRACT Traditional graph representations are insufficient for modelling real‐world phenomena involving multi‐entity interactions, such as collaborative projects or protein complexes, necessitating the use of hypergraphs. While hypergraphs preserve the intrinsic nature of such complex relationships, existing models often overlook temporal evolution in
