Periodic Solutions of a Singular Equation With Indefinite Weight
Advanced Nonlinear Studies, 2010 Abstract Motivated by some relevant physical applications, we study the existence and uniqueness of T-periodic solutions for a second order differential equation with a piecewise constant singularity which changes sign. Other questions like the stability and robustness of the periodic solution are considered.

Multiplicity of Solutions for Gradient Systems Using Landesman-Lazer Conditions
Abstract and Applied Analysis, 2010 We establish existence and multiplicity of solutions for an elliptic system which presents resonance at infinity of Landesman-Lazer type. In order to describe the resonance, we use an eigenvalue problem with indefinite weights.

A Dual‐Branch Flux‐Based Extended Memristor Model With Machine‐Learning‐Assisted Calibration
Advanced Electronic Materials, EarlyView.Multilayer oxide memristors integrated in crossbar arrays are described through a dual‐branch, flux‐controlled compact model. A three‐stage calibration workflow combining Latin hypercube sampling, Bayesian optimization, and gradient‐based refinement extracts device parameters from experimental data.

Children’s knowledge of indefinite and definite reference [PDF]
, 1990 After reviewing previous theoretical and empirical investigations, the decision is made that an understanding of both "Familiarity' and 'Specificity' must be necessary for a full appreciation of indefiniteness/definiteness.
