Microring Resonator Dispersion Metrology With Neural Networks
Nanophotonics, Volume 15, Issue 17, 11 September 2026.We present a machine learning framework for inverse and forward characterization of microring resonators, inferring geometry and material dispersion from sparse spectral data. The approach achieves nanometer‐scale accuracy and > 99% material identification, while reconstructing full dispersion spectra.

Supporting weakly Pareto optimal allocations in infinite dimensional nonconvex economies [PDF]
In this paper, we prove a new version of the Second Welfare Theorem for economies with a finite number of agents and an infinite number of commodities, when the preference correspondences are not convex-valued and/or when the total production set is not ...

Optimizing Enterprise Capital Structure Allocation Using the NSGA‐III Algorithm
Engineering Reports, Volume 8, Issue 9, September 2026.This work applies the NSGA‐III algorithm with nondominated sorting and reference‐point guidance to corporate capital‐structure optimization, tackling uneven Pareto‐front distribution and low convergence efficiency in high‐dimensional multiobjective optimization.

Hidden Convexity in Partially Separable Optimization [PDF]
The paper identifies classes of nonconvex optimization problems whose convex relaxations have optimal solutions which at the same time are global optimal solutions of the original nonconvex problems. Such a hidden convexity property was so far limited to

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Nonconvex bargaining problems [PDF]
This paper studies compact and comprehensive bargaining problems for n players and axiomatically characterize the extensions of the three classical bargaining solutions to nonconvex bargaining problems: the Nash solution, the egalitarian solution and the

Technical Note—Bounding Nonconvex Programs by Conjugates [PDF]
Operations Research, 1973 We point out that the Lagrangian dual conjugation in response space provides a stronger bound and requires less computation than conjugate convexification in decision space. A homotopy is then described to lend economic interpretation in the presence of gaps.

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping
Advanced Materials, Volume 38, Issue 45, 13 August 2026.Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...
