Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, Volume 59, Issue 4, Page 991-1004, August 2026.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Effects of Physical Activity on Brain White Matter Integrity Are Region‐, Dose‐, and Age‐Dependent: Findings From the Population‐Based Rhineland Study

Aging Cell, Volume 25, Issue 8, August 2026.
Physical activity is related to more aligned white matter fibers and microstructural reorganization of the brain. Body weight, cardiometabolic, and inflammatory factors could partly mediate the effects of physical activity on brain white matter microstructure. The effects of physical activity on the brain are age‐ and region‐specific.

The Cognitive Costs of Sleep Deprivation in Ultra‐Endurance Cycling: Insights From the Race Across France

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT For athletes in endurance sports, who compete over several days and in unpredictable conditions, managing sleep–wake rhythms is critical to ensure optimal performance and minimise the risks to safety. Despite its growing popularity, the role of sleep management on ultracycling performance has received little attention.

A Novel Framework for Understanding Multiaxial Fatigue of SBR Through Monitored Tension‐Torsion Tests

Strain, Volume 62, Issue 4, August 2026.
A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...

Haemodynamic responses to small muscle mass exercise before and after lung transplantation in end‐stage chronic obstructive pulmonary disease

Experimental Physiology, Volume 111, Issue 8, Page 3604-3619, 1 August 2026.
Abstract Cardiovascular control during exercise is impaired in chronic obstructive pulmonary disease (COPD). The central cardiopulmonary pathologies in COPD might drive the local muscle vascular abnormalities. We hypothesised that contracting muscle perfusion and O2 utilisation improve after lung transplantation (LTx) in COPD.
