An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

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

Immunology, EarlyView.
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 ...

On the effect of the contact surface definition in the Cartesian grid finite element method

Advanced Modeling and Simulation in Engineering Sciences, 2018
The definition of the surface plays an important role in the solution of contact problems, as the evaluation of the contact force is based on the measure of the gap between the solids.

Assessment of Methacrylated Poly(ε‐Caprolactone)/Silanized Hydroxyapatite Composite Resin for High‐Resolution Scaffolds via Vat Photopolymerization 3D Printing

Polymers for Advanced Technologies, Volume 37, Issue 2, February 2026.
ABSTRACT High‐resolution, biocompatible scaffolds are essential for reproducible tissue engineering and remain challenging to fabricate with vat photopolymerization due to cure‐depth control and limited bioactivity of neat polymers. This work investigated the mechanical, surface, and biological properties, as well as the high‐resolution 3D printability,
