Bifurcation of eigenvalues in nonlinear problems with antilinear symmetry [PDF]
, 2016 Many physical systems can be described by nonlinear eigenvalues and bifurcation problems with a linear part that is non-selfadjoint e.g. due to the presence of loss and gain.

Partial sum of eigenvalues of random graphs [PDF]
, 2020 summary:Let $G$ be a graph on $n$ vertices and let $\lambda _{1}\geq \lambda _{2}\geq \ldots \geq \lambda _{n}$ be the eigenvalues of its adjacency matrix.

Advanced Materials Interfaces, EarlyView.Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

On higher order eigenvalues of the spherical laplacian operator [PDF]
, 2010 In this paper, we use the boundary measurements of normalized eigenfunctions to estimate the variation of the corresponding eigenvalues. With this form, we can show that some eigenvalues, as functions of domain, possess monotonicity as the domain varies ...

Metastability and small eigenvalues in Markov chains [PDF]
, 2000 In this letter we announce rigorous results that elucidate the relation between metastable and low-lying eigenvalues in Markov chains in a much more general setting and with considerable greater precision as was so far available.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
