Fatigue performance of auxetic meta-biomaterials.

open access: yesActa Biomaterialia, 2021
Meta-biomaterials offer a promising route towards the development of life-lasting implants. The concept aims to achieve solutions that are ordinarily impossible, by offering a unique combination of mechanical, mass transport, and biological properties ...

Fatigue performance in patients with chronic insomnia. [PDF]

open access: yesFront Neurosci, 2022
Insomnia is associated with fatigue and poor driving performance, thus increasing the risk of traffic accidents. This study aimed to evaluate the effect of fatigue on driving in patients with chronic insomnia in a free-flow traffic scenario and car-following scenario, and to investigate the relationships between driving performance, cognitive function,

Effects of Post-processing on the Surface Finish, Porosity, Residual Stresses, and Fatigue Performance of Additive Manufactured Metals: A Review

open access: yesJournal of materials engineering and performance (Print), 2021
Additive manufacturing (AM) has attracted much attention due to its capability in building parts with complex geometries. Unfortunately, AM metals suffer from three major drawbacks, including high porosity, poor surface finish, and tensile residual ...

The HMOX2 polymorphism contributes to the carotid body chemoreflex in European sea-level residents by regulating hypoxic ventilatory responses

open access: yesFrontiers in Medicine, 2022
This study investigates whether a functional single nucleotide polymorphism of HMOX2 (heme oxygenase-2) (rs4786504 T>C) is involved in individual chemosensitivity to acute hypoxia, as assessed by ventilatory responses, in European individuals.

Influence of internal and surface defects on the fatigue performance of additively manufactured stainless steel 316L

open access: yesInternational Journal of Fatigue, 2022
The additive manufacturing (AM) process generates new material challenges with associated features like internal defects and inherent surface roughness, reducing fatigue performance. This paper introduces a new approach to characterizing internal defects

Translating Fatigue to Human Performance [PDF]

open access: yesMedicine & Science in Sports & Exercise, 2016
Despite flourishing interest in the topic of fatigue-as indicated by the many presentations on fatigue at the 2015 Annual Meeting of the American College of Sports Medicine-surprisingly little is known about its effect on human performance. There are two main reasons for this dilemma: 1) the inability of current terminology to accommodate the scope of ...
