Journal of Applied Toxicology, EarlyView.ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

JCPP Advances, EarlyView.Abstract Background Evidence of how parenting stress evolves during early childhood is limited. We aimed to identify parenting stress trajectories involving children aged 1 month to 3 years, and to determine their perinatal predictors. Methods Data were obtained from 3133 mothers in the Tokyo Teen Cohort (TTC), a population‐based cohort of children ...

Procedia Engineering, 2017 One of the most important tasks in sheet metal forming is the prediction of formability. The common criterion for ductile fracture in industrial application is the evaluation of the so-called Forming Limit Curve (FLC). The determination of FLCs is standardized in the international standard 12004-2 by two different experimental methods, the Marciniak ...

A tipping point for tipping points
Oikos, EarlyView.Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.

Formability Assessment of 3D-Printed ABS Sheets Using Nakajima Test
Abstract This study explores the formability of acrylonitrile butadiene styrene (ABS) sheets produced by the fused filament fabrication 3D-printing process. The ABS sheets, fabricated with a diameter of 80 mm, were subjected to the Nakajima test.

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids
PLANTS, PEOPLE, PLANET, EarlyView.Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.

Journal of Field Robotics, EarlyView.ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.
