Clustering cluster algebras with clusters

open access: yesAdvances in Theoretical and Mathematical Physics, 2023
Classification of cluster variables in cluster algebras (in particular, Grassmannian cluster algebras) is an important problem, which has direct application to computations of scattering amplitudes in physics. In this paper, we apply the tableaux method to classify cluster variables in Grassmannian cluster algebras $\mathbb{C}[Gr(k,n)]$ up to $(k,n)=(3,

Clustering [PDF]

open access: yes, 2008
Clustering techniques are used to arrange genes in some natural way, that is, to organize genes into groups or clusters with similar behavior across relevant tissue samples (or cell lines). These techniques can also be applied to tissues rather than genes.

Cluster-cluster clustering

open access: yesThe Astrophysical Journal, 1985
The cluster correlation function xi sub c(r) is compared with the particle correlation function, xi(r) in cosmological N-body simulations with a wide range of initial conditions. The experiments include scale-free initial conditions, pancake models with a coherence length in the initial density field, and hybrid models.

Genetic analysis of fibre quality and yield related traits in desi cotton (Gossypium arboreum L.)

open access: yesElectronic Journal of Plant Breeding, 2023
The present investigation was undertaken in 48 desi cotton genotypes to study the genetic divergence and character association for fibre quality and yield related traits. The results of Mahalanobis D2 analysis indicated the presence of considerable

Recent advances in polyoxometalate-based lanthanide–oxo clusters

open access: yesPolyoxometalates, 2023
Polyoxometalate (POM)-based lanthanide-oxo clusters (LnOCs) are a class of polynuclear lanthanide–oxygen complexes formed by polyoxometalate stabilization through oxygen bridges in which POMs can be viewed as multidentate inorganic ligands.

Clusters and Superclusters in the Las Campanas Redshift Survey [PDF]

open access: yes, 2003
Two-dimensional high-resolution density field of galaxies of the Las Campanas Redshift Survey (LCRS) with a smoothing length 0.8 Mpc/h is used to extract clusters and groups of galaxies, and a low-resolution field with a smoothing length 10 Mpc/h to find
