A Systematic Computational Framework for Practical Identifiability Analysis in Mathematical Models Arising from Biology

open access: yesAdvanced Science, EarlyView.
A systematic computational framework is developed for practical identifiability analysis in biological models. The framework establishes a rigorous definition, introduces efficient coordinate‐based identifiability metrics, and proposes novel regularization strategies.

Exact solution of the relationship between the eigenvalue discreteness and the behavior of eigenstates in Su–Schrieffer–Heeger lattices

open access: yesNew Journal of Physics
The interplay between eigenvalue discreteness and eigenstate localization is a fundamental characteristic of one-dimensional Su–Schrieffer–Heeger (SSH) lattices.

Perturbation formula of eigenvalues in a singularly perturbed domain

open access: yesJournal of the Mathematical Society of Japan, 1993
The author deals with partial degeneration of a domain (the Dumbbell shaped domain) and an asymptotic behavior of a certain class of eigenvalues of the Laplacian with Neumann boundary conditions. For small \(\zeta>0\), the domain \(\Omega(\zeta)\) is expressed as follows \(\Omega(\zeta)=D_ 1\cup D_ 2\cup Q(\zeta)\subset\mathbb{R}^ n\) where \(Q(\zeta)\)

Hierarchical Prediction and Perturbation of Chromatin Organization Reveal How Loop Domains Mediate Higher‐Order Architectures

open access: yesAdvanced Science, EarlyView.
HiCGen introduces a hierarchical deep learning framework to predict genome organization across spatial scales using DNA sequences and genomic features. The model enables cross‐cell‐type predictions and in silico perturbation analysis, revealing correlations between loop domains and higher‐order structures.

Second Order Eigensensitivities of Singularly Perturbed Systems

open access: yesJournal of King Saud University: Engineering Sciences, 1994
In this paper, second order eigenvalue sensitivities are derived with respect to the singular perturbation parameter whose variation changes the reduced system order.

A Dirichlet-to-Neumann approach for the exact computation of guided modes in photonic crystal waveguides

open access: yes, 2013
This works deals with one dimensional infinite perturbation - namely line defects - in periodic media. In optics, such defects are created to construct an (open) waveguide that concentrates light.

Perturbation thèorems for the generalized eigenvalue problem

open access: yesLinear Algebra and its Applications, 1982
AbstractGiven a matrix pair Z = (A, B), the perturbation of its eigenvalues (α, β) is studied. Considering two pairs Z, W as points of the Grassman manifold Gn, 2n and its eigenvalues as points in G1, 2, the projective complex plane, the distance of the spectra, measured in the chordal metric in G1, 2, is bounded by some distance of the matrix pairs in

Topological Singularities and Edge‐State Coupling Enable Robust on‐Chip Slow Light

open access: yesAdvanced Science, EarlyView.
This work demonstrates the first experimental observation of a topological quantum‐interference‐like effect in a 1D on‐chip system, utilizing two topological mechanisms for robust slow light. Topological charges ensure immunity to parameter deviations, while edge states provide robustness against disturbances.

Universal Parametric Correlations of Eigenvalues of Random Matrix Ensemble

open access: yes, 1994
Eigenvalue correlations of random matrix ensembles as a function of an external perturbation are investigated vis the Dyson Brownian Motion Model in the situation where the level density has a hard edge singularity. By solving a linearized hydrodynamical
