Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, EarlyView.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.

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.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

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 ...
