Geometric morphometric analyses of intragenus (Campylomormyrus) and intergenus hybrids in mormyrid fish

Abstract Natural hybrids within the weakly electric mormyrid fish genus Campylomormyrus have not been documented in the wild. However, recent advances have enabled the artificial production of both intragenus ( Campylomormyrus ) and intergenus ( Campylomormyrus and Gnathonemus )...

Outcomes in JIA have greatly improved, but we can still do better

Abstract Outcomes for children and adolescents with juvenile idiopathic arthritis (JIA) have improved substantially over the past two decades, driven by biologic and targeted synthetic DMARDs, treat-to-target strategies with regular standardized assessments, and multidisciplinary...

Perceived Responsibility and Capability for Smart Speaker Privacy Controls: A Cross-National Study in Germany and the UK

Smart speakers are popular assistants but require constant processing of voice data, thus, posing threats to users’ and bystanders’ privacy. While different privacy controls are available it is unknown who people perceive as responsible at the three stages conceptualization, impl...

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...

Drug Survival of Omalizumab and Factors Associated With Discontinuation in Chronic Urticaria

Importance Omalizumab is a recommended second-line therapy for chronic urticaria (CU), yet clinical evidence regarding long-term drug survival and determinants of discontinuation remains limited. Understanding drug survival patterns may inform clinical decision-making and patient...

Rehabilitation and the post-intensive care syndrome across the recovery continuum: a narrative review

Purpose Improved survival from critical illness has produced a growing population of intensive care unit (ICU) survivors with new or worsened physical, cognitive, and mental-health impairment, defined as post-intensive care syndrome (PICS), and frequent distress among families/ca...

Long-Term Average Impulse Control with Mean Field Interactions

Abstract This paper analyzes and explicitly solves a class of long-term average impulse control problems with a specific mean-field interaction. The underlying process is a general one-dimensional diffusion with appropriate boundary behavior. The model is motivated by application...

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

ABSTRACT In this work, we investigate the diffusion‐controlled growth mechanism and kinetics of gallium arsenide (GaAs) islands on CMOS‐compatible Si(001) nanotip wafers using nanoheteroepitaxy by gas‐source molecular beam epitaxy. Si nanotips embedded in a silicon dioxide (SiO 2...

Ontological security under invasive life conditions: Thinking With a blackberry on Canada's sunshine coast

The Sunshine Coast of southern British Columbia, Canada, is extensively populated by Himalayan blackberries ( Rubus armeniacus ), a species introduced to North America in the late nineteenth century. In their coexistence with other species, humans often categorize nonhuman life f...

Exploring cerebral small vessel disease signatures in familial Parkinson’s disease

Familial Parkinson's disease (PD) and vascular parkinsonism (VP) present overlapping features and may co-exist. To investigate whether PD and VP may share a potential pathogenic link and to what extent white matter hyperintensities may influence PD phenotype, we used the modified...

Computational Detection of Implicit Philosophical Authority in Eustratius of Nicaea: A Pilot Study

Abstract: Byzantine engagement with ancient philosophical sources is well documented in cases of explicit citations, but implicit borrowing—unmarked by citation—has so far not seen a systematic study. This paper presents a computational pipeline for detecting such implicit author...

Upcycling waste apples into platform chemicals: pilot-scale production of lactic and succinic acids

Abstract The conversion of renewable biological resources into value-added products is essential for supporting the transition to a sustainable bioeconomy. This study explores the use of waste apples—a byproduct generated in large quantities along the fresh apple supply chain—as...

Beyond Closed-Shell Photochemistry: Singlet Oxygen Generation Driven by 10H-Phenothiazine Radical Cation

Abstract Phenothiazines are widely studied as closed-shell photosensitizers; however, their open-shell oxidized forms remain largely unexplored in photochemical contexts. Here, we investigate the photophysics and reactivity of the radical cation of 10H-phenothiazine (PHT•+) using...

“Then you are left on your own”: barriers to guideline-based speech and language therapy for aphasia along the patient journey in the German-speaking healthcare context

Abstract Background Although evidence-based recommendations for aphasia rehabilitation exist, guideline-based speech and language therapy is still not consistently implemented in routine care. Previous studies have described barriers to therapy participation from the perspective...

“Not only standing for, but standing up for diversity”: an intersectional qualitative analysis of how university students embody and resist discrimination

Abstract Background Universities are key social institutions that shape student health, wellbeing, and future trajectories. However, they are also embedded in, and contribute to, existing social inequities. Students holding marginalised positions consistently report experiences o...

Multilingual large language models do not comprehend all natural languages to equal degrees

Abstract Large Language Models (LLMs) play a critical role in how humans access information. While their core functionality relies on the ability to comprehend written requests, our understanding of this ability is currently constrained, because most benchmarks evaluate LLMs in h...

Learning from model failure: insights from an AI/SHAP-based temporal error decomposition of tracer-aided ecohydrological modelling

Abstract. Process-based models (PBM) have served as testing grounds for hypotheses, being falsified and refined through model evaluation based on temporally complex PBM errors. Yet, conventional evaluation practices (e.g., performance metrics, visual inspection across time series...

Signals of Communicative Intent Enhance the Impact of Emotional Messages from Human Speakers, While Effects for Robots are Attenuated

Abstract The present work investigated humans’ responses to robots’ verbal emotional expressions. To this end, the interplay of agent characteristics and signals of communicative intent on emotional word processing was examined. In two behavioral studies (N1 = 36, N2 = 72), parti...

Anticipating the hospital of the future: stakeholder perspectives on 6G technology requirements in health care

PURPOSE: The ongoing 6G standardization process is largely driven by technical advancements, but with limited consideration of sector-specific needs, particularly in health care. The current scientific literature primarily focuses on technical aspects, offering minimal empirical...

Reproducible human reward imaging phenotypes exhibit differential sensitivity to dopamine D2 receptor antagonism

Abstract Human reward processing varies along cue-centric and outcome-centric axes, but a reproducible mechanistic account of individual variation in incentive salience attribution has been lacking. Using fMRI across five cohorts (N-total=1,251; N1=890; N2=245; N3=34; N4=48; N5=3...
