Causal Language in Post Titles Shapes Deeper Topological Structures of Online Conversations

Causal reasoning is fundamental to human understanding and information organization. People prefer causal explanations because they offer coherence, predictability, and a sense of control. Conversational structures shape how knowledge and perspectives are shared, validated, and a...

Bridging Knowledge Gaps in Clinical AI: An Activity Theory Perspective on Interdisciplinary Data Work for Telehealth

Advanced AI technologies are increasingly integrated into clinical domains to advance patient care. The design and development of clinical AI technologies necessitate seamless collaboration between clinical and technical experts. However, such interdisciplinary teams are often un...

Prospective associations between living in a smart growth community and children’s obesity risk measured by BMI percentile and waist circumference‑to‑height ratio

Obesity continues to be among the leading health concerns in the U.S. Smart Growth (SG) community development principles encourage physical activity and social engagement, which hold the potential to mitigate obesity risks in youth. This study examined the prospective association...

Age-Friendly Health Systems in Hospital at Home: An Integrated Healthcare System Cross-Sectional Survey

Background Age-Friendly Health Systems (AFHS) is an evidenced-based initiative structured on the 4Ms framework (What Matters, Medications, Mentation, and Mobility) to improve care for older adult patients and has been implemented across the United States in various care settings....

Asymptotic FDR Control with Model-X Knockoffs: Is Moments Matching Sufficient?

We propose a unified theoretical framework for studying the robustness of the model-X knockoffs framework by investigating the asymptotic false discovery rate (FDR) control of the practically implemented approximate knockoffs procedure. This procedure deviates from the model-X kn...

The Scope Creep Myth: How Hierarchical Visibility Drives Escalation Rather Than Departure in Multi-Agent Systems

When an orchestrator delegates a subtask to a worker agent, it must decide how much context from the supervising hierarchy to expose. Current engineering practice diverges sharply: systems either isolate workers to their immediate assignment or forward the full execution transcri...

A stakeholder-engaged process to design and implement the Assessment of Cognitive Complaints Toolkit for Alzheimer’s Disease (ACCT-AD) in primary care

Background: Dementia is underdiagnosed, particularly in primary care settings where most people receive their healthcare. These is a need for tools to assist with the diagnosis of dementia by primary care clinicians, who greatly outnumber specialists. Objective: To describe the c...

Criminal Trial Attorney Questions About Parent Conflict when Children Testify Against a Parent in Child Sexual Abuse Cases

When a parent is accused of child sexual abuse (CSA), parent conflict raises concerns about allegation credibility. However, little is known about how attorneys question children about parent conflict. We examined 21,863 question-answer pairs from 53 testimonies of 6- to 17-year-...

Psychological Need Satisfaction During Physical Activity: Differences Across Physical and Social Contexts in a Large-Scale Study

Physical inactivity is a public health problem. Accordingly, there is growing interest in whether engaging in physical activity (PA) that satisfies psychological needs (e.g. safety, novelty) is more likely to be sustained. Physical and social PA contexts (e.g. where, with whom, l...

Orthogonal dualities of dynamic stochastic higher spin vertex models, using the Drinfeld twister

Abstract We introduce a new algebraic method to construct duality functions for integrable dynamic models. This method will be implemented on dynamic stochastic higher spin vertex models, where we prove that the resulting duality functions between the dynamic stochastic higher sp...

Hunting for microsatellite instability in long-read data with Owl

Abstract Microsatellite instability (MSI) is a key biomarker of mismatch repair deficiency and response to immunotherapy, yet most existing genomic detection methods are optimized for short-read sequencing and rely on small panels of homopolymer markers, limiting the ability to c...

Model Falsification for Predicting Dynamical Responses of Uncertain Structural Systems

Abstract Accurate prediction of the dynamical response of a structural system depends on appropriate modeling of that system. However, modeling becomes increasingly challenging when numerous candidate models are available to describe the system behavior. Although different model...

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...

Polarity-aware knowledge graph reveals diet–microbiome–health mechanisms with relevance to muscle, immune and metabolic aging

Diet profoundly influences gut microbial composition and metabolism, yet mechanistic pathways linking dietary exposures to human health remain fragmented across the literature. To systematically organize and integrate this evidence, we constructed an evidence-weighted Diet-Microb...

A Commotion in the Mind: Direct and Indirect Associations of Moral Injury Symptom Severity and Stoicism with Suicide Risk in U.S. Military Veterans

Moral injury (MI) and stoicism have mixed independent associations with suicide risk among U.S. military veterans, yet little is known about how these constructs interact. We examined direct and indirect associations among MI symptom severity, stoicism, and suicide risk. Study pa...

Echoes across the divide: incivility and the fragmentation of issue publics in immigration discourse

As immigration remains one of the most polarizing issues in U.S. politics, public discourse around it has become increasingly uncivil, especially on social media. This longitudinal study examines how incivility spreads and escalates across ideologically opposed issue publics on X...

Semi-universality of CFT$_d$ entropy at large spin

The thermal partition function, Z <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mi>Z</mml:mi> </mml:math> , of a CFT_d <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"> <mml:mrow> <mml:mi>C</mml:mi> <mml:mi>F</mml:mi> <mm...

Assessing molecular, cellular and transcriptomic bases of laminar perfusion and cytoarchitecture coupling in the human cortex

Understanding how cellular architecture organizes cortical function requires mesoscopic approaches that resolve structure-function coupling in vivo. Here we introduce cerebral blood flow (CBF) and cell-body staining intensity (CSI) similarity index (CCSI), a localized similarity...

Circles of Confidence for Multi‐Label Geometry Completion

Abstract Inside–outside classification is widely used for geometry processing tasks such as surface reconstruction, geometry completion, and calculating signed distance fields. We introduce a new integral formulation of this problem, which assigns confidence scores that points ar...
