Participation builds trust, not framing: insights from a national energy-transition experiment

Institutional trust is a critical determinant of public cooperation in the energy transition, yet little is known about how different framings of government communication influence trust in practice. This study reports results from a large-scale national experiment (N ≈ 3000) emb...

Associations between reduction of hypotension and treatment intensity in hypotension prediction index studies

BACKGROUND: The Hypotension Prediction Index (HPI) is developed for proactive prevention of hypotension and existing meta-analyses report reduced hypotension with HPI-guided management in comparison with a strategy based on MAP alerts of 65 mmHg. Still, validation studies suggest...

Effects of exercise on muscle strength and characteristics in rheumatic diseases and sarcopenia: Protocol for the Care for Muscle (C4M) Study

Objective Muscle weakness is prevalent in rheumatoid arthritis (RA), osteoarthritis (OA) and sarcopenia (SARC). Endurance exercises may improve mitochondrial function and oxidative capacity, while strength exercises are thought to stimulate myofibrillar protein synthesis. This st...

Management of Acute Periodontal Conditions—The EFP S2k Level Clinical Practice Guideline

BACKGROUND: The European Federation of Periodontology (EFP) has developed Clinical Practice Guidelines (CPGs) for the treatment of periodontitis and for the management of peri-implant diseases. In accordance with the 2018 Classification, acute periodontal conditions are character...

Hospital-Level Determinants of Mortality After Pancreas Surgery

OBJECTIVE: To identify modifiable hospital-level determinants of mortality after pancreas surgery and assess their cumulative protective effects through the development of a Hospital Resource Index (HRI) on a global scale. BACKGROUND: Ninety-day mortality rates after pancreas sur...

A functional analytic theory for differential equations on Banach spaces with slowly evolving parameters

Abstract This paper provides a functional analytic approach to differential equations on Banach spaces with slowly evolving parameters. We develop a Fenichel-like theory for attracting subsets of critical manifolds via a Lyapunov–Perron method. This functional analytic approach t...

Static Effective Hamiltonians for Molecular Systems through RPA-Based Downfolding

Abstract Green’s function-based downfolding methods construct effective Hamiltonians of reduced dimension that capture dynamical correlations of an electronic environment through effective potentials acting on the active space only. Using methods based on the constrained random p...

Machine learning-based emission rate estimates of global methane super-emissions

Abstract. Methane, the second most important anthropogenic greenhouse gas, has a global warming potential more than 80 times that of carbon dioxide over a 20-year period. Given its decadal atmospheric lifetime, reducing anthropogenic methane emissions is critical for limiting nea...

Words of Authority: Evaluating the Impact of Law Enforcement Messaging on a Hacker Forum

Law-enforcement agencies increasingly target individuals considered at risk of cybercrime, yet evidence of these interventions’ effectiveness remains limited. This study evaluated an intervention in which law enforcement publicly replied to hacker-forum users with warnings about...

Invited perspectives: Towards usable compound event research

Abstract. Supporting stakeholders with science-based decision-making to mitigate and adapt to climate change impacts is a central mandate of the climate research community. In particular, mapping out scenario-dependent climate risk landscapes is one of the most pressing challenge...

Is burnout in home care professionals associated with older adult client outcomes? Exploring depressive symptoms, pain, health-related quality of life, and the moderating role of dependency

BACKGROUND: As populations age, home care is becoming increasingly important. Demanding working conditions in this strained sector may contribute to burnout; however, little is known about whether burnout in home care organisations is associated with care recipients' outcomes. OB...

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...

Persona-prompted LLM agents achieve modest but genuine prediction of human social media reactions

Abstract Social media platforms mediate how billions form opinions and engage with public discourse. As autonomous AI agents increasingly participate in these spaces, understanding their behavioral fidelity becomes critical for platform governance and democratic resilience. Previ...

The Reproducibility Promotion Plan for Funders–a co-created set of recommendations to foster reproducible research practices

Abstract Reproducibility is a critical component of research integrity, enhancing the quality, efficiency and trustworthiness of scientific knowledge. Despite increasing attention, reproducibility remains insufficiently prioritized within the scientific agenda. Research funders a...

Robust inference and correlates from genetic associations with personality

Personality traits describe stable differences in how people think, feel and behave, and how they interact with and experience their social and physical environments1,2. Many questions remain unanswered about associations between DNA and personality traits, such as their robustne...

Application Usability, Engagement, and Postpartum Weight Retention: Secondary Analysis of the INTER-ACT Randomized Controlled Trial.

Objective: To examine whether perceived usability of the INTER-ACT application influences postpartum weight loss and whether this effect is mediated by application use, motivational power, and implementation of lifestyle recommendations. Patients and Methods: Dutch-speaking women...

Multiscale characterization of cortical signatures in positive and negative schizotypy:a worldwide ENIGMA study

Positive and negative schizotypy reflect distinct patterns of subclinical traits in the general population associated with neurodevelopmental and schizophrenia-spectrum pathologies. Yet, a comprehensive characterization of the unique and shared neuroanatomical signatures of these...

Brokerage, power and individual innovation:When do brokers act on their structural advantage?

Prior research has found that brokers, those who stand between two disconnected parties, may access non-redundant information that is conducive to higher innovation. However, research has also shown that occupying brokering network positions does not systematically translate into...

Resonance transformations for the $$(2,2p+1)$$ minimal string via $$x-y$$ swap: a proof of Artemev’s conjecture

Abstract This paper contains a proof of a recent conjecture of Artemev that connected the resonance transformations for the $$(2,2p+1)$$ ( 2 , 2 p + 1 ) minimal string to the $$x-y$$ x - y swap in the theory of topological recursion.

Time-dependent prognostic value of coronary plaque burden and hyperemic myocardial blood flow

Abstract Rationale The time-dependent contributions of coronary atherosclerotic plaque burden and myocardial ischemia to clinical outcomes in suspected coronary artery disease (CAD) remain uncertain. This study aimed to evaluate the temporal associations of quantitatively assesse...
