A Functional-Analytic Framework for Sensitivity Analysis in Actuarial Valuation

Risks
Actuarial valuation of long-duration insurance liabilities depends on assumptions regarding mortality, lapse behavior, and discount rates, making it important to understand how valuation outcomes respond to changes in these assumptions.

Deep‐Learning‐Driven High‐Fidelity In Vivo Hyperspectral Fluorescence Imaging Under Extreme Photon‐Limited Conditions

Advanced Science, EarlyView.
Highly overlapping fluorescent signals become distinguishable in photon‐limited living organisms via advanced imaging with intelligent reconstruction. The resulting in vivo hyperspectral imaging capability reveals nanoplastic uptake and circulation in live zebrafish, providing a new approach for studying complex biological and environmental processes ...

Intrinsically Design‐Rule‐Compliant Nanophotonic Inverse Design via Learned Generative Manifolds

Laser &Photonics Reviews, EarlyView.
A generative reparameterization framework for nanophotonic inverse design is introduced, restricting optimization to a learned manifold of design‐rule‐compliant geometries. Unlike conventional penalty‐based approaches, fabrication constraints are encoded intrinsically within the design representation.

Trade‐Policy Exposure and Managerial Adjustment Margins: Regime‐Dependent Evidence From Corporate Tax‐Base Outcomes

Managerial and Decision Economics, EarlyView.
ABSTRACT Trade‐policy shocks raise visible operating pressure on firms through sourcing costs, supplier exposure, and market‐serving choices. A direct operating‐margin interpretation points to production reconfiguration, pricing changes, or supply‐chain adjustment.

Qualitative and sensitivity analysis on simple epidemic model (SIR-MODEL): ensuring well-posedness and stability

Journal of Statistical Sciences and Computational Intelligence
This study investigates the dynamics of infectious disease transmission using an SIR (Susceptible-Infected-Recovered) model. We examine the model’s positivity, equilibrium points, basic reproduction number using the next generation matrix method, and sensitivity to key parameters using the sensitivity index method.

Optimal Design of Elastic Plates: Hybrid Numerical Method Based on Homogenization and Shape Derivative

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.
