Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities
Advanced Photonics Research, EarlyView.We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

Mathematical model for the basilar membrane as a two dimensional plate
Electronic Journal of Differential Equations, 1999 In this paper we present two mathematical models for the basilar membrane. In the first model the membrane is represented as an annular region. In the second model the basilar membrane is treated as a rectangular region.

Methodology for Topological Interface Engineering in 2D Photonic Crystals
Advanced Photonics Research, EarlyView.This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.

Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces
Advanced Photonics Research, EarlyView.Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.

Upper bounds for eigenvalues of a nonlinear eigenvalue problem
Journal of Mathematical Analysis and Applications, 1978 with compact, positive definite operators A, B in a complex separable Hilbert space. Turner [ll, 121 has studied this problem (see also Weinberger [13], Eisenfeld [4], W erner [14], Langer [S]). He describes the spectrum and obtains variational principles for the eigenvalues; furthermore he gives some estimates and bounds for the eigenvalues.

Fundamental tone of minimal hypersurfaces with finite index in hyperbolic space
Journal of Inequalities and Applications, 2016 Let M be a complete minimal hypersurface in hyperbolic space H n + 1 ( − 1 ) $\mathbb {H}^{n+1}(-1)$ with constant sectional curvature −1. We prove that if M has a finite index and finite L 2 $L^{2}$ norm of the second fundamental form, then the ...

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.
