Psychological stress catalyses free radical–mediated activation of coagulation in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study provides the first in vivo evidence that acute psychological stress triggers systemic free radical formation and prothrombotic remodelling of blood clot microstructure. By inducing stress in healthy participants, we observed a significant increase in oxidative stress (A•−), a shortening of the intrinsic pathway of ...

Global smoothness estimation of a Gaussian process from regular sequence designs

open access: yes, 2014
We consider a real Gaussian process $X$ having a global unknown smoothness $(r_{\scriptscriptstyle 0},\beta_{\scriptscriptstyle 0})$, $r_{\scriptscriptstyle 0}\in \mathds{N}_0$ and $\beta_{\scriptscriptstyle 0} \in]0,1[$, with $X^{(r_{\scriptscriptstyle ...

Early evolutionary history of the seed

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Early Maturation of Heart Rate Variability in Very Preterm Infants Depends on Neonatal Factors and Is Associated With Neurodevelopmental Risk

open access: yesActa Paediatrica, Volume 115, Issue 6, Page 1191-1201, June 2026.
ABSTRACT Aim This study investigated central autonomic network maturation deviations using a previously defined machine learning model set to estimate a functional maturation age (FMA) from heart rate variability (HRV) analysis. We investigated whether these deviations were associated with maternal, fetal, perinatal, or postnatal complications and with

Application of Fractal Interpolation in Rainfall Series in Hydrodynamic Models

open access: yesRenmin Zhujiang
In order to solve the problem of inaccurate simulation results caused by low-precision rainfall time data to hydrological and hydrodynamic models, the fractal interpolation of the iterative function system was used to interpolate the rainfall time data ...

Vegetated Canopy Heterogeneity Footprints in the Roughness Sublayer

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Turbulent flows over horizontally homogeneous rough surfaces are categorized as rough‐wall boundary layer flows, while flows over homogeneous vegetated canopies are better described through a mixing‐layer analogy. At present, numerous studies have investigated canopy density as a transition mechanism between rough‐wall and mixing‐layer‐type ...

Intelligent materials for on‐demand electromagnetic absorption

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
This review introduces an innovative “stimulus‐state‐property” paradigm, facilitating a fundamental transition from static to dynamically intelligent electromagnetic wave absorption (EMWA). The key advancement lies in the synergistic integration of external fields with structurally engineered metamaterials and tunable components.

Semi-Rings, Semi-Vector Spaces, and Fractal Interpolation

open access: yesFractal and Fractional
In this paper, we introduce fractal interpolation on complete semi-vector spaces. This approach is motivated by the requirements of the preservation of positivity or monotonicity of functions for some models in approximation and interpolation theory. The
