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

open access: yesJ
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.

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

open access: yesFatigue &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 ...

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

open access: yesJournal 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

open access: yesJournal 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.

Experimental and Numerical Simulation Investigation of Cement Sheath Integrity during Multi-Stage Fracturing in Offshore Tight Oil Reservoir

open access: yesJournal of Marine Science and Engineering
The integrity of the cement sheath is susceptible to failure during multi-stage fracturing. In this study, the failure mechanisms of cement sheath integrity during multi-stage fracturing in the A offshore tight oil reservoir wells were investigated.

Correlation Between Functional Scores and Objective Gait Parameters Following Rotating Hinge Knee Megaprosthesis Reconstruction

open access: yesOrthopaedic Surgery, EarlyView.
Using a wearable gait system, we compared MSTS, TESS, and KSS with objective spatiotemporal metrics in patients after rotating‐hinge knee reconstruction. TESS showed the highest median R2 and stronger correlations with walking velocity and step/stride length, outperforming MSTS and KSS.

Physiological markers of Trauma‐related nightmares among military personnel suffering from PTSD: A multicenter home‐recording study

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Aim Despite being one of the most disabling symptoms of post‐traumatic stress disorder (PTSD)—disrupting sleep continuity, reinforcing hyperarousal, and worsening psychiatric comorbidity—the physiological signature of Trauma‐related nightmares (TRNs) under naturalistic sleep conditions remains poorly characterized.

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...
