Exceptional points at bound states in the continuum in photonic integrated circuits
Nanophotonics, 2022 We propose the realization of exceptional points (EP) at bound states in the continuum (BIC), with two coupled strips, made of an electron-beam resist and patterned on the thin film photonic integrated platform, which makes possible etchless photonics ...

Localization on low-order eigenvectors of data matrices [PDF]
arXiv, 2011 Eigenvector localization refers to the situation when most of the components of an eigenvector are zero or near-zero. This phenomenon has been observed on eigenvectors associated with extremal eigenvalues, and in many of those cases it can be meaningfully interpreted in terms of "structural heterogeneities" in the data.

Approximate eigenvectors as preconditioner
Linear Algebra and its Applications, 2000 Given approximate eigenvector matrix of a Hermitian nonsingular matrix H, the spectral decomposition of H can be obtained by computing H´=*H and then diagonalizing H´. This work addresses the issue of numerical stability of the transition from H to H´ in finite precision arithmetic.

Electronic CPA‐Laser Having Enhanced Sensitivity and Tunability
Advanced Electronic Materials, EarlyView.Coherent perfect absorber (CPA) laser points are peculiar singularities possessed by parity−time symmetric systems. They have demonstrated great potential for sensing applications, albeit hindered by the non‐tunability and structural limitations. This work introduces a tunable CPA laser system in a reader‐sensor scheme, whose sensitivity can be further

A Globally Convergent MCA Algorithm by Generalized Eigen-Decomposition [PDF]
International Journal of Computational Intelligence Systems, 2011 Minor component analysis (MCA) are used in many applications such as curve and surface fitting, robust beam forming, and blind signal separation. Based on the generalized eigen-decomposition, we present a completely different approach that leads to ...

The eigenvectors of the right-justified Pascal triangle [PDF]
arXiv, 2000 We find the eigenvalues and eigenvectors of the n by n matrix with (i,j) entry \binom(i-1,n-j), establishing a conjecture of Peele and Stanica. Curiously, the eigenvectors can be chosen to form a matrix which is its own inverse.

Agribusiness, EarlyView.ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.
