Fourier Expansion‐Based Approach to the Parameter Space of Classical Systems

Annalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We propose a new approach to compute the classical metric tensor (CMT) and the Hannay curvature using Fourier series expansions in action‐angle variables. This approach circumvents the need for complex time‐domain integrals or the construction of generating functions, replacing them with algebraic combinations of Fourier coefficients. We prove

A Fully Automated Pipeline for Vertebral Structural Assessment From Medical Images. Application Under Metastatic Conditions

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 7, July 2026.
We present an automated CT‐to‐simulation workflow to estimate structural response and fracture risk in metastasis‐affected vertebrae. Deep learning performs vertebral identification and segmentation, while CPD assigns geometry‐aware boundary conditions.

Resilient Biophysical Phenotype of Memory CD4 + T Cells in Long‐Lived Mice

Immunology, Volume 178, Issue 2, Page 363-374, June 2026.
Aging is associated with increased stiffness and reduced migratory capacity of memory CD4+ T cells; however, these biophysical declines do not persist in exceptionally long‐lived mice. Instead, long‐lived individuals preserve T cell mechanics, migration and intracellular architecture, supporting mechanical resilience as a hallmark of successful immune ...

A multi‐level approach for multi‐objective optimization in process eco‐design

Environmental Progress &Sustainable Energy, Volume 45, Issue 3, May/June 2026.
Abstract This work addresses a central challenge in process eco‐design: how to efficiently integrate environmental and economic criteria—often conflicting—into early design stages while managing the high dimensionality of Life Cycle Assessment (LCA) indicators.

Effect of PWHT and Electrical Parameters on Austenitic Phase, Sigma Phase and Corrosion in Duplex Steels S32205

Engineering Reports, Volume 8, Issue 4, April 2026.
Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.
