Process‐Induced Anisotropy and Fracture Behavior of Pellet‐3D Printed PLA and PLA/Flax Biocomposites

Polymer Composites, Volume 47, Issue 18, Page 16442-16462, 20 September 2026.
Fused Granular Fabrication of PLA and PLA/flax biocomposites, followed by tensile testing and fracture surface analysis to evaluate the effects of raster orientation and layer number on anisotropy and fracture behavior. ABSTRACT Fused granular fabrication (FGF) enables cost‐effective, large‐scale polymer additive manufacturing; however, the mechanical ...

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

Materials Genome Engineering Advances, Volume 4, Issue 3, August 2026.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

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 ...
