Stress-correlated stereom organization in the echinoid tubercle reveals hierarchical mechanical integration

Echinoid tests consist of a highly porous skeletal microstructure (stereom) optimized in terms of functional performance. One of the most mechanically demanding components of the test is the tubercle, which forms the mechanical interface between the test plates and spines and is...

Habitat-use flexibility may promote the spread of Asian weatherloaches in Europe

Asian weatherloaches have expanded their range across Europe, potentially increasing competitive pressure on the conservation-dependent native European weatherfish Misgurnus fossilis . Because interspecific interactions are potentially mediated by benthic habitat use, we quantifi...

The relationship between health literacy and active and successful aging: a cross-sectional study of active aging service center

Abstract Background While successful aging focuses on physical health and disease prevention, active aging offers a broader framework encompassing social participation and security. Health literacy is considered a vital tool in achieving these outcomes, yet its specific impact on...

Consistency between zonal mean stratospheric and total column ozone trends (2000–2024)

This study presents an updated assessment of stratospheric and total column ozone trends over the 2000–2024 period using six merged limb-profile datasets and six merged total ozone datasets. Long-term changes were quantified using a multiple linear regression framework that accou...

Beyond Ce–U Charge Transfer: Strain and Polarons in Epitaxial Ce1– x U x O2(111)

Abstract The redox chemistry of mixed ceria-based oxides is commonly interpreted in terms of direct charge transfer between neighboring cations. In the Ce1–xUxO2 system, this corresponds to the oxidation of U4+ into U5+ accompanied by the reduction of Ce4+ into Ce3+. In this work...

Honeydew microbial ecology: A neglected frontier in multitrophic networks

Abstract Honeydew, the sugary excretion produced by sap-feeding Hemiptera, is one of the most common carbohydrate resources in many plant-based food webs. Honeydew supports a wide range of organisms, including ants, pollinators, (hyper-)parasitoids wasps, predatory insects, and m...

SurvSurf: a partially monotonic neural network for first-hitting time prediction of intermittently observed discrete and continuous sequential events

Abstract We propose SurvSurf, a neural-network-based survival model for direct, simultaneous probabilistic prediction of first-hitting times of sequential events from baseline. Unlike existing models, SurvSurf is theoretically guaranteed to never violate the monotonic relationshi...

Can You Feel My Pain? Neural‐Behavioural Changes in Caregiver–Infant Dyads During Ostracism

ABSTRACT Behavioural and neural coordination during infant‐caregiver social interaction is crucial for early emotional development and effective emotional regulation abilities later in life. This is particularly relevant to help infants deal with challenging social situations, su...
