Schur Indices, BPS Particles, and Argyres-Douglas Theories [PDF]
, 2015 We conjecture a precise relationship between the Schur limit of the superconformal index of four-dimensional $\mathcal{N}=2$ field theories, which counts local operators, and the spectrum of BPS particles on the Coulomb branch.

A Validity Index for Fuzzy Clustering Based on Bipartite Modularity
Journal of Electrical and Computer Engineering, 2019 Because traditional fuzzy clustering validity indices need to specify the number of clusters and are sensitive to noise data, we propose a validity index for fuzzy clustering, named CSBM (compactness separateness bipartite modularity), based on bipartite

Validation of the Regional Authority Index [PDF]
Regional & Federal Studies, 2008 This article validates the Regional Authority Index (RAI) with seven widely used decentralization indices in the literature. A principal axis analysis reveals a common structure. The major source of disagreement between the RAI and the other indices stems from the fact that the RAI does not include local governance, whereas most other indices do.

A Clustering Validity Index Based on Pairing Frequency
IEEE Access, 2017 Clustering is an important problem, which has been applied in many research areas. However, there is a large variety of clustering algorithms and each could produce quite different results depending on the choice of algorithm and input parameters, so how
