GENERIC Formulation and Small-Angle Limit for Kinetic Wave Equations

Abstract In this paper, we formulate the three-wave and four-wave kinetic equations into the GENERIC framework and formally derive a small-angle limit for the four-wave equation. This limit is akin to the well-known grazing limit from the kinetic Boltzmann equation to the kinetic...

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...

Infinite-dimensional nonlinear stationary Fokker–Planck–Kolmogorov equations

Abstract We prove existence of a probability solution to the nonlinear stationary Fokker–Planck–Kolmogorov equation on an infinite dimensional space with a centered Gaussian measure γ with a unit diffusion operator and a drift of the form − x + v ( p , x ), where v is a bounded m...

The role of a major sport event for shaping gender-specific attitudes towards democracy

This study examines the role of the UEFA EURO 2024 in shaping women and men residents’ attitudes towards democracy. The German government adds a new perspective to the national soft power literature by considering a major sport event a tool for promoting democracy. Social role th...

Towards a deep-learning genomic tool for risk stratification and diagnostic support in sporadic ALS

Abstract Background A variety of common and rare genetic factors have been implicated in the development of amyotrophic lateral sclerosis (ALS), and the evidence is that a genetic component is present in most affected individuals. However, our current understanding of ALS genetic...

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...

Asymptotics of ruin probabilities in a subordinated Cramér-Lundberg model

We study a dynamic model of a non-life insurance portfolio. The foundation of the model is a compound Poisson process that represents the claims side of the insurer. To introduce clusters of claims appearing, e.g. with catastrophic events, this process is time-changed by a Lévy s...

Anemia prevalence and its association with dietary diversity, tea consumption, body mass index, and medical history among female university students in southern coastal Bangladesh

Abstract Background Anemia is a significant public health concern among female university students in Bangladesh, and the situation may be worse in coastal areas due to socioeconomic and environmental factors. The purpose of this study was to assess the prevalence and associated...

Pediatric intensive care follow-up in Germany is rarely established and highly heterogeneous: a nationwide survey of 20 PICUs

BACKGROUND: Survival after pediatric critical illness has improved substantially, but many survivors and their families experience long-term physical, neurocognitive, psychological and social sequelae, summarized as post-intensive care syndrome in pediatrics and in families. Stru...

Age-related differences in embodying a tool under visual deprivation

Abstract Tool embodiment refers to the integration of external objects into action-related body representations. Although vision is often assumed to support this process, it remains unclear how tool use under short-term visual deprivation affects explicit ownership and agency acr...

PLASTID ENVELOPE ION CHANNELS (PEC1/2) link Ca 2+ and jasmonic acid signaling in plant cells

Plants constantly encounter adverse environmental interactions. One organelle is particularly specialized in stress signaling and phytohormone synthesis: the plastid. Calcium (Ca 2+ ), a key second messenger, is known to intersect with cellular phytohormone signaling networks. Wh...

Maximal subgroups in torsion branch groups

We study the maximal subgroups of branch groups and obtain a criterion that ensures that certain spinal groups are contained in the class \mathcal{MF} of groups with all maximal subgroups of finite index. This allows us to construct branch groups within \mathcal{MF} exhibiting no...

Tumor Necrosis is Associated with an Increased Metastatic and Cardiovascular Risk in Paragangliomas: A Single-Center Series and Meta-Analysis Comparing Necrosis and Cystic Degeneration in Paragangliomas

Abstract Paragangliomas (PGLs) are rare neural crest–derived tumors with highly variable morphology and clinical behavior. These tumors can present with cystic and necrotic alterations that may influence the clinical presentation of affected patients. However, prevalence and clin...

A multilevel analysis of the predictive effects of internal migration and region of residence on women’s empowerment in Nigeria

BACKGROUND: Despite growing research interest on the influences of migration and regions of residence on human behaviors, studies on the influences of migration and region of residence on women empowerment especially in sub-Saharan Africa are lacking. Thus, this study investigate...

From Product-Quality Complaints to Patient-Safety Triage: A Structured Narrative Review and Proposed PRCS-TRACE Framework

Product-quality complaints are usually handled as pharmaceutical quality-system events, yet defects in sterility, potency, identity, packaging, labelling, storage, distribution or delivery-device function may affect medication use, treatment continuity and patient outcomes. This...

Tribenzotriquinacene Fused Dimers (“Fusodimers”)—Synthesis and Host–Guest Properties

ABSTRACT The synthesis and structural properties of two stereoisomeric tribenzotriquinacene (TBTQ) derivatives, syn ‐ 4 and anti ‐ 4 , in which two rigid TBTQ bowls share a common benzene ring, are described. Owing to the orthogonal orientation of the three indane wings in each o...

Can parent–child interactions help reduce socioeconomic differences in language development? Results of a German birth cohort study

Abstract Aim Children from socioeconomically disadvantaged families often have lower developmental outcomes than their socioeconomically more advantaged peers. In early childhood, language development (LD) in particular is a key competence for further socialization. There is a ne...

Shifting AAV9 tropism by binding moiety insertion enhances transduction of tumor cell lines and human glioblastoma explants

Abstract Tumor-specific targeting remains a major obstacle for the development of precision cancer therapies. For several tumors and specifically glioblastoma (GBM), an aggressive brain tumor with poor prognosis, more effective treatments are urgently needed. Recombinant adeno-as...

Crossing effects in the tactile temporal order judgment task: a meta-analysis

Abstract The tactile temporal order judgment (TOJ) task is widely used in multisensory neuroscience. Participants judge which of two tactile stimuli, one on each hand, came first. A key finding is that TOJ performance declines when the arms are crossed, likely due to interactions...

The Moment of Delivery in Online Retailing: How Courier Types and Inoculation Messages Affect Reactions to the Last-Mile Experience

Online customers’ journeys span several touchpoints, which typically do not involve any interpersonal interactions with online retailers—except at the moment of delivery (MoD). When retailers use third-party courier services to fulfill orders, they relinquish control over this cr...
