How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs

American Journal of Primatology, Volume 88, Issue 7, July 2026.
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

Estudio del mecanismo de la corrosión del recubrimiento de cobre químico usado en la protección de los espejos

Revista de Metalurgia, 2002
El defecto conocido como "nube o mancha", que aparece en los espejos plateados fabricados usando las tecnologías convencionales, se atribuye a la corrosión del recubrimiento de cobre ocasionado por agentes agresivos que pueden atravesar las capas de ...

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.

Performance of the Direct Current Electric Potential Difference (DCEPD) Method for Crack Extension Measurement in Fracture Mechanics Specimens Exhibiting Split Delaminations

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2963-2980, July 2026.
ABSTRACT This work investigates the performance of the direct current electric potential difference (DCEPD) method for measuring crack extension ( ∆a) during fracture toughness tests of ductile steels exhibiting delaminations perpendicular to the main crack plane, known as splits.

The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

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 ...
