Numerical simulation of charged fullerene spectrum
Mathematical Modelling and Analysis, 2019 The mathematical model of the ground state electron spectrum of a charged fullerene is constructed on the basis of the potential of a charged sphere and the spherically symmetric potential of a neutral fullerene, derived in a single-electron self ...

Inverse Spectral Problems for Dirac Operators with Summable Matrix-Valued Potentials [PDF]
Integral Equations and Operator Theory, 2012 We consider the direct and inverse spectral problems for Dirac operators on $(0,1)$ with matrix-valued potentials whose entries belong to $L_p(0,1)$, $p\in[1,\infty)$. We give a complete description of the spectral data (eigenvalues and suitably introduced norming matrices) for the operators under consideration and suggest a method for reconstructing ...

On a Problem of Harary and Schwenk on Graphs with Distinct Eigenvalues [PDF]
, 2014 Harary and Schwenk posed the problem forty years ago: Which graphs have distinct adjacency eigenvalues? In this paper, we obtain a necessary and sufficient condition for an Hermitian matrix with simple spectral radius and distinct eigenvalues.

Advanced Functional Materials, EarlyView.Bloodstream infections (BSI) are one of the leading causes of mortality and morbidity in both civilian and military populations. This paper summarizes recent progress in novel treatment strategies to manage BSI arising from both bacterial and fungal pathogens using molecules, particles, and materials to elicit host‐directed immunity.

Shock and Vibration, 1996 It is shown that the usual method for estimating the coherence functions (ordinary, partial, and multiple) for a general multiple-input! multiple-output problem can be expressed as a modified form of Cholesky decomposition of the cross-spectral density ...

Spectral-Kinetic Coupling and Effect of Microfield Rotation on Stark Broadening in Plasmas
Atoms, 2014 The study deals with two conceptual problems in the theory of Stark broadening by plasmas. One problem is the assumption of the density matrix diagonality in the calculation of spectral line profiles.

Robust Spectral Clustering via Matrix Aggregation
IEEE Access, 2018 Spectral clustering has become one of the most popular clustering algorithms in recent years. In real-world clustering problems, the data points for clustering may have considerable noise.

A relaxation scheme for computation of the joint spectral radius of matrix sets
, 2009 The problem of computation of the joint (generalized) spectral radius of matrix sets has been discussed in a number of publications. In the paper an iteration procedure is considered that allows to build numerically Barabanov norms for the irreducible ...
