Relationships of Cognitive Function With Subsequent Device‐Measured Physical Activity and Sedentary Time in Healthy Individuals and Those With Bipolar Disorder: Findings From the UK Biobank

Acta Psychiatrica Scandinavica, EarlyView.
ABSTRACT Background In bipolar disorder (BD), physical inactivity and sedentary behaviour are prevalent and have been linked to BD's cognitive symptoms, although the directionality of these links is not clear. This proof‐of‐concept study examined whether cognitive function during mid‐ and later‐life was prospectively related to physical activity and ...

Computational Investigation on the Combined Effect of Applied Strain and Pore Configuration on Strain Concentrators in Additively Manufactured Metals

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Metal additive manufacturing (AM) provides a pathway for creating highly optimized components that would be difficult to produce using traditional manufacturing methods. However, regardless of printing parameters or postprocessing, porosity remains a prevalent challenge in AM components because strain concentrates in the vicinity of the pore ...

Evolution of the Damping Ratio Considering Cyclic Confining Pressure Under Intermittent Cyclic Loading

Buildings
The damping ratio is essential to conducting dynamic analysis for underground engineering under traffic loading. Variations in the damping ratio are usually studied using cyclic triaxial tests with continuous cyclic loading; however, intermittent loading

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

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

Journal of Sleep Research, EarlyView.
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.

The Effects of the Choice of Liquefaction Criteria on Liquefaction in Soils with Plastic Fines

J
Cyclic triaxial tests are widely used in laboratory studies to assess the liquefaction susceptibility of soils. Although standardized procedures exist for conducting these tests, there is no universally accepted criterion for defining liquefaction.

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1843-1854, March 2026.
ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...
