Three Hypergraph Eigenvector Centralities
SIAM 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.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Appropriate medical therapy (AMT) is first‐line treatment for patients with chronic rhinosinusitis (CRS). We evaluated inflammatory structure, treatment‐induced changes, and biomarker‐outcome associations in AMT‐managed patients. Methods Fifty‐one CRS patients were evaluated before and after AMT which included a combination of oral ...

Asymptotic Inference for Eigenvectors
The 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

Journal of Applied Polymer Science, EarlyView.Morphology, mechanical properties and vibration damping properties of polyurea/GNP nanocomposites. ABSTRACT Studying structural dynamics of polyurea (PU) is pivotal to analyze its vibration‐damping features. In this study, a graphene‐reinforced PU coating with enhanced mechanical and damping properties was developed.

Quantum Carnot Bound from Petz Recovery Maps
Advanced Physics Research, EarlyView.A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.

Eigenvectors in bottleneck algebra
Linear Algebra and its Applications, 1992 The paper deals with a characterization of the eigenvectors in terms of the associated graph and with an alternative way of computing them. Upper and lower bounds for all eigenvectors are given. The approach is illustrated by several numerical examples.

Efficient Dynamics: Reduced‐Order Modeling of the Time‐Dependent Schrödinger Equation
Advanced Physics Research, EarlyView.Reduced‐order modeling (ROM) approaches for the time‐dependent Schrödinger equation are investigated, highlighting their ability to simulate quantum dynamics efficiently. Proper Orthogonal Decomposition, Dynamic Mode Decomposition, and Reduced Basis Methods are compared across canonical systems and extended to higher dimensions.
