Electronic Journal of Differential Equations, 2000 Sensitivity analysis is often used in high fidelity numerical optimization to estimate design space derivatives efficiently. Typically, explicit codes are combined with the adjoint formulation of continuous sensitivity analysis, which requires the ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Recent results have shown that domain‐uniform stabilizability and detectability imply spatial exponential decay of perturbations in optimally controlled hyperbolic PDEs on one‐dimensional domains. This domain‐uniform stabilizability and detectability can be achieved only if the control domain is distributed over the whole spatial domain such ...

Performance of a Mixed Least‐Squares Finite Element Formulation With Application in Poroelasticity
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT A mixed least‐squares finite element method (LSFEM), previously proposed for the theory of porous media (TPM), is further investigated in this work. Finite deformation of a fully saturated, incompressible solid–fluid binary system is studied using the LSFEM.

Sparsity‐Driven Source Localization in Tomographic Sensing Applications
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Hyperspectral standoff detection systems such as Focal Plane Array (FPA) Fourier Transform Infrared (FTIR) spectrometers provide high spatial resolution in detecting airborne chemical contaminants that are invisible to the human eye but potentially hazardous. When two such systems are operated simultaneously with a suitable opening angle, they

Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,

Projectivity, continuity, and adjointness: quantales, Q-posets, and Q-modules
Theory and Applications of Categories, 2016 In this paper, projective modules over a quantale are characterized by distributivity, continuity, and adjointness conditions. It firstly generalizes the Joyal-Tierney characterization of projective/flat \(Q\)-modules [\textit{A. Joyal} and \textit{M. Tierney}, Mem. Am. Math. Soc. 309, 71 p.

An Optimal Control Framework for Multi‐Species Harvesting in the Southern Black Sea
Natural Resource Modeling, Volume 39, Issue 4, November 2026.ABSTRACT The management of marine fisheries requires balancing ecological sustainability with economic profitability, particularly in ecosystems vulnerable to overexploitation. This study develops a multi‐species optimal control modeling framework for the southern Black Sea, focusing on three key species: horse mackerel (Trachurus mediterraneus) as ...
