Systematic Study of PDMS Optical Waveguides for Pressure Sensing Using Design of Experiments

Journal of Applied Polymer Science, Volume 143, Issue 12, March 20, 2026.
A response surface methodology was used to systematically evaluate the impact of mix ratio and cure conditions on PDMS optical waveguide properties for pressure sensing. Mix ratio significantly influenced compression sensitivity, compressive modulus, and propagation loss, while cure temperature primarily affected refractive index.

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 3, Page 544-564, March 2026.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...
