Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

An Experimental PIV/POD Study on the Sequentially Coupled Flow Field of Swirl and Multiple Jets

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
The stepwise flow reconstruction induced by sequential coupling of swirl, primary jets, and dilution jets was experimentally investigated in a model combustor using high‐speed PIV and proper orthogonal decomposition (POD). Three nonreacting configurations were compared: pure swirl, swirl plus primary jets, and swirl with both primary and dilution jets.

Structural Stability of the Moore–Gibson–Thompson Heat Equation in a Semi‐Infinite Cylindrical Domain

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This work analyzes the continuous dependence of solutions to the Moore–Gibson–Thompson (MGT) equation formulated via Green–Naghdi Type III second gradient elasticity theory. The governing system is defined on a semi‐infinite cylindrical domain, subject to homogeneous Dirichlet conditions on the lateral boundary.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, Volume 37, Issue 48, December 3, 2025.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
