Partly zero eigenvectors [PDF]
Linear and Multilinear Algebra, 1990 This paper is concerned with the forced presence or absence of zero components in an eigenvector. Relative to a fixed matrix Awith eigenvalue λ, we characterize the strictly nonzero part of a partly zero eigenvector associated with λ. We also give a sufficient condition for a fixed matrix to have a partly zero eigenvector, and discuss several examples ...

Advanced Science, EarlyView.CellPolaris decodes how transcription factors guide cell fate by building gene regulatory networks from transcriptomic data using transfer learning. It generates tissue‐ and cell‐type‐specific networks, identifies master regulators in cell state transitions, and simulates TF perturbations in developmental processes.

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 ...

Deflated BiCGStab for linear equations in QCD problems [PDF]
, 2007 The large systems of complex linear equations that are generated in QCD problems often have multiple right-hand sides (for multiple sources) and multiple shifts (for multiple masses).

Finding Octonionic Eigenvectors Using Mathematica
, 1998 The eigenvalue problem for 3x3 octonionic Hermitian matrices contains some surprises, which we have reported elsewhere. In particular, the eigenvalues need not be real, there are 6 rather than 3 real eigenvalues, and the corresponding eigenvectors are ...

A Clarification on Quantum‐Metric‐Induced Nonlinear Transport
Advanced Science, EarlyView.How does the quantum metric truly govern the nonlinear transport? The longstanding theoretical discrepancies are resolved in quantum‐metric‐induced nonlinear transport and the correct intrinsic nonlinear conductivity is identified. Furthermore, a toy model is engineered to suppress the competing effects, uniquely highlighting the role of quantum metric

The Number of Eigenvalues of a Tensor
, 2010 Eigenvectors of tensors, as studied recently in numerical multilinear algebra, correspond to fixed points of self-maps of a projective space. We determine the number of eigenvectors and eigenvalues of a generic tensor, and we show that the number of ...

Advanced Science, EarlyView.This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.
