Three Hypergraph Eigenvector Centralities

open access: yesSIAM Journal on Mathematics of Data Science, 2019
Eigenvector centrality is a standard network analysis tool for determining the importance of (or ranking of) entities in a connected system that is represented by a graph. However, many complex systems and datasets have natural multi-way interactions that are more faithfully modeled by a hypergraph.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

open access: yesThe Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

New fractional cosine transform and its application

open access: yesTongxin xuebao, 2005
A new Fractional Cosine Transform was proposed. It was a weighted combination of the first two integer-order cosine transforms of the original signal, and it has the same eigenvectors as the cosine transform’s, but the different eigenvalues which have a ...

Asymptotic Inference for Eigenvectors

open access: yesThe Annals of Statistics, 1981
Abstract : Asymptotic procedures are given for testing certain hypotheses concerning eigenvectors and for constructing confidence regions for eigenvectors. These asymptotic procedures are derived under fairly general conditions on the estimates of the matrix whose eigenvectors are of interest. Applications of the general results to principal components

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

New approach for 2-D spectrum estimation——parameter weight method

open access: yesTongxin xuebao, 2006
A new approach of 2-D MUSIC algorithm was proposed.Using the eigenvector and the eigenvalue of the co-variance matrix simultaneously,the method was composed of two one-dimension searching and avoided the costly 2-D searching.The pairings of the estimated
