We apply hierarchical clustering methods on streamtubes for visualization and analysis. Streamtubes are integrated in the major eigenvector field of the DTI data set. In a 256 × 256 × 50 data set, our algorithm can generate tens of thousands of streamtubes. It is hard to find features in a dense set of undistinguished tubes. Thus it is important to impose some structural information on the stre...

We study three representations of hierarchies of partitions: dendrograms (direct representations), saliency maps, and minimum spanning trees. We provide a new bijection between saliency maps and hierarchies based on quasi-flat zones as used in image processing and characterize saliency maps and minimum spanning trees as solutions to constrained minimization problems where the constraint is quas...

A proposal for a fundamental theory is described in which classical and quantum physics as representation of the universe gigantic dendrogram are unified. The latter explicate order structure corresponding to purely number-theoretical implicate given by p-adic numbers. This number field was zero-dimensional, totally disconnected, disordered. Physical systems (such electrons, photons) sub-dendro...

Allelic patterns and genetic distances were examined in a collection of 103 foreign and Brazilian mango (Mangifera indica) accessions in order to develop a reference database to support cultivar protection and breeding programs. An UPGMA dendrogram was generated using Jaccard's coefficients from a distance matrix based on 50 alleles of 12 microsatellite loci. The base pair number was estimated ...

Hierarchical clustering is a simple and reproducible technique to rearrange data of multiple variables and sample units and visualize possible groups in the data. Despite the name, hierarchical clustering does not provide clusters automatically, and "tree-cutting" procedures are often used to identify subgroups in the data by cutting the dendrogram that represents the similarities among groups ...

Thyme is an important medicinal plant in cosmetic, pharmaceutical and food industries. The first step for breeding of thyme is evaluating of genetic variation and relationship between thyme’s accessions. Therefore, the objective of this study was to evaluate morphology, chemical and molecular variation of 13 accessions of Thyme medicinal plant. ANOVA showed significant differences between acces...

In this study, old and recent honey bee, Apis mellifera L., 1758 (Hymenoptera: Apidae) specimens were compared using geometric morphometrics. The bee samples collected from different apiaries in Edirne, Balıkesir, Çanakkale, Denizli Muğla Provinces, Gökçeada (an Aegean island) Turkey 1987-1988 under a project of the Agricultural Research Institute same locations 2017. mean values determined for...

Hierarchical clustering is one of the standard methods taught for identifying and exploring underlying structures that may be present within a dataset. Students are shown examples in which dendrogram, visual representation hierarchical clustering, reveals clear structure. However, practice, data analysts today frequently encounter datasets whose large scale undermines usefulness dendrogram as v...

The present investigation on “Assessing the Nutritional and antinutritional componants of promising kabuli chickpea (Cicer arietinum L.) genotypes” was carried out with an objective to analyze different 20 genotypes for various nutritional anti-nutritional components. highest protein content (25.37%) phytic acid (12.29 mg g-1) were recorded in genotype GJGK-1828. value total sugar observed ICCV...
