A stabilized finite element method for a Morpho-Visco-Poroelastic Model

Studying the structure of soft tissues is important and relevant in biology, particularly in some diseases, such as tumor growth and dermal contraction after burn injury. Based on the complicated characteristics of the tissue and for the sake of a better understanding of the unde...

Association Between Adverse Childhood Experiences and Digital Addiction in Mainland Chinese Children and Adolescents: A Three-Level Meta-Analytic Review

Mainland China’s large youth internet-user population, rapid digitalization, and substantial sociocultural and regional heterogeneity provide a unique context for examining how adverse childhood experiences (ACEs) relate to digital addiction among children and adolescents. Despit...

Lifting primordial non-Gaussianity above the noise

Primordial non-Gaussianity (PNG) in Large Scale Structures is obfuscated by the many additional sources of non-linearity. Within the Effective Field Theory approach to Standard Perturbation Theory, we show that matter non-linearities in the bispectrum can be modeled sufficiently...

Cross-national clinical exchange in child psychiatry across cultural contexts and mental health systems: a scoping review

Abstract Background Clinical practice in child and adolescent psychiatry (CAP) relies on internationally shared, empirically grounded guidelines, yet their application is influenced by socioeconomic and cultural differences. Cross-national clinical exchange allows health professi...

International Protocol for the Study of Amorphous Charred Objects in Archaeology (IPSACO 1.0)

Abstract Archaeobotanists around the world increasingly recognise that, alongside commonly studied materials such as seeds, fruits, wood charcoal, and chaff, archaeobotanical samples also contain fragments of carbonised organic (and sometimes inorganic) matter that vary in shape...

Modulating task-outcome value to mitigate real-world procrastination via noninvasive brain stimulation

Procrastination is a prevalent behavioral problem associated with individual health and societal productivity. A leading model posits that procrastination reflects an imbalance between task aversiveness and the pursuit of positive task outcomes, yet this theoretical framework has...

Context-dependent siderophore exploitability shapes microbial community structure

Siderophores are classically viewed as shared iron-scavenging public goods, yet their ecological roles in multispecies communities remain incompletely understood. Here, we establish a synthetic microbial community to dissect how different siderophores, their uptake compatibility...

Energy management for hydrogen refueling stations: A synergistic approach of cascade compression architecture and deep reinforcement learning

With the growth of the fuel cell electric vehicles market, hydrogen refueling stations have become vital infrastructure bridging hydrogen production and dispensing. In hydrogen refueling stations, the compression process is a necessary and the most energy-intensive stage requirin...

Reliability, validity, and change over time in disinhibited and disruptive behaviors assessed with the age‐adapted disruptive behavior diagnostic observation schedule in children aged 5–12 years with ADHD

Abstract Background Previous research has shown that the disruptive behavior diagnostic observation schedule (DB‐DOS) is a valid and reliable clinic‐based assessment of disinhibited and disruptive behaviors in preschoolers. We adapted the DB‐DOS for use in children aged 5–12 year...

Changing Topic Bias in Biomedical Science Maps by Linking Documents Through Alternative Data Sources: Policy Documents, Patents, Authors, Facebook, and Twitter

Abstract Purpose Traditional science maps cluster documents into topics but are inherently biased toward clustering certain topics over others. This study investigates the extent to which topic bias can be influenced through the selection of data sources used to construct documen...

Classifier congruency effects in Spanish–Chinese noun phrase production: Behavioral and electrophysiological evidence

Abstract Mandarin Chinese employs a classifier system requiring classifiers obligatorily positioned between demonstratives or numerals and nouns in noun phrases (NPs; e.g., 一张桌子 , [one specific-classifier-zhang1 table] , ‘one table’). While classifier congruency effects have...

Galaxy luminosity functions from far-UV to submillimetre at z = 0 in the COLIBRE simulations

Abstract We present predictions from the colibre cosmological hydrodynamical simulations of galaxy formation for the present-day galaxy luminosity functions (LFs) at wavelengths ranging from the far-ultraviolet (FUV) to the submillimetre. The simulations are post-processed with t...

Ancient DNA preservation in the Caribbean

Abstract Ancient DNA (aDNA) analysis has transformed how we study human migration, species dispersals and environmental change, but poor preservation remains a major challenge. This is especially true in tropical settings, where hot and humid conditions accelerate DNA decay. Beca...

Scenario based dynamic material flow analysis of Dutch macro infrastructure stocks: assessing future material demand and circularity potentials

Abstract Enabling circularity in infrastructure systems depends on effectively recovering secondary raw materials from end-of-life (EoL) stocks to offset future demand for virgin materials. This study develops a dynamic material flow analysis model to forecast future raw material...

Isotope analysis reveals mobility of the earliest cattle herds in northern Europe

Abstract Human mobility was intrinsic to the farming communities of the Linear Pottery culture (c. 5500 − 4900 BCE). Much less is known about the mobility patterns of the earliest farmers north of the Linear Pottery zone, particularly in the Netherlands. Here, people of the Early...

Personal-MetaboHealth, an actionable health check in middle age, is improved by an effective lifestyle intervention in those at risk

Abstract Background MetaboHealth represents a novel indicator of overall health in middle age and may potentially be suitable as actionable health check in prevention strategies. MetaboHealth is a blood-based metabolomic composite score that predicts a wide range of age-related c...

Regime shift in climate governance: HFCs, the UNFCCC, and the Montreal Protocol

Abstract This article explains why and how hydrofluorocarbon governance shifted from the UNFCCC to the Montreal Protocol through the Kigali Amendment. This shift of hydrofluorocarbon governance from the central climate regime to the ozone regime is surprising: while the Montreal...

Turning ecology into economy: who provides biodiversity knowledge for institutional investors?

Biodiversity is emerging as a material issue for institutional investors, driven by a growing concern for nature-related risks. This presents a challenge to the financial sector as institutional investors require metrics and tools to develop their investment strategies. Yet, biod...

A Storage Process with Alternating Lévy Input

In this paper, we study a queueing process for which the dynamics are changed once the workload in the queue exceeds a predefined threshold, and these new dynamics stay in force until the queue is emptied, at which point the previous dynamics are again reinstalled. For general sp...

Clustering effects on the Dark Siren determination of H 0: A simulation study

Abstract We investigate the cosmological power of gravitational wave (GWs) events without electromagnetic counterparts using high-resolution, cosmological simulations that include realistic clustering. We assume a near-future detector network (LVK + LIGO India in O5), with sky lo...
