Climate change may lead to larger fires, greater area burned, and more reburning across interior Alaska

Boreal forests are experiencing rapid warming, altering fire regimes and vegetation dynamics. However, projecting future fire activity remains challenging given complex interactions among climate, vegetation, and landscape features. We used the LANDIS-II forest landscape simulati...

LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run

Abstract LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable production of high quality detector data and rapid noise mitigation efforts allow the extr...

Cross-sectional Comparison of the PREVENT and Pooled Cohort Equations for 10-Year Atherosclerotic Cardiovascular Risk Estimates in a U.S. Cohort of Black and Latina Transgender Women with HIV

Background: Transgender women with HIV face higher rates of atherosclerotic cardiovascular disease (ASCVD) than the general population. However, ASCVD risk estimators use binary sex variables that may misclassify their risk. We examined the effects of sex variable inputs in the P...

Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics

The next generation of particle physics experiments will face an era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environments and operational constraints. Harnessing these data for scientific discovery demands real-time infere...

New Heegaard Floer slice genus and clasp number bounds

We define several concordance invariants using knot Floer homology, which give improvements over known slice genus and clasp number bounds from Heegaard Floer homology. We also prove that the involutive correction terms of Hendricks and Manolescu give both a slice genus and a cla...

Melt Production and Volatile Release From Thermochemical Mantle Plumes

Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain p...

The emotion regulation and recognition account of empathy‐related processes in autism: a multimodal, multilevel case–control study

BACKGROUND: Recent evidence suggests that many autistic individuals exhibit heightened emotional responsiveness to others' affect despite greater difficulty recognizing others' emotions and accurately inferring their perspectives. This study introduces and preliminarily evaluates...

Insights from more than a year of ongoing episodic lava fountaining at Kīlauea

Episodic lava fountaining is rare globally, with only three occurrences from Kīlauea (Hawaii) since 1823. Beginning in December 2024, an eruption within the summit crater, Halemaʻumaʻu, has produced 54 fountaining episodes to date, each lasting typically for hours and separated b...

Pysammos 1.0.0: a discrete-to-continuum transformation Python tool to analyse the rheology of granular materials

Abstract. Granular flow processes involving different interstitial fluids and coupling regimes are widespread in both natural systems (e.g., landslides, rock avalanches, river sediment transport) and industrial applications (e.g., aggregates in concrete manufacturing, powder tech...

Occlusal enamel complexity in beaver (Rodentia: Castoridae) genera from John Day Fossil Beds National Monument, Oregon, USA

Abstract Dental adaptations to abrasive wear include increased tooth crown height and complexity of occlusal enamel folds. These trends have been studied extensively in ungulates, and some other mammal groups with hypsodont dentition. Beavers (family Castoridae) represent diverse...

How ventures maintain stakeholder support amidst operational legitimacy threats

Abstract Research Summary We explore how ventures mitigate operational legitimacy threats— threats that originate within the venture and challenge claims relating to the venture's ability to deliver on its promised value proposition . Through an inductive study of four ventures w...

Core-grammatical innovation in real time: radical and rapid constructionalization in Chinese

Abstract Recent research in Diachronic Construction Grammar and Creative Construction Grammar has begun to uncover nongradual cases of linguistic creativity. Two gaps nevertheless remain: the scarcity of documented cases of radical and rapid innovation in core grammar, and the ne...

Comparative population genomics reveal stark differences in the genomic structure and drivers of isolation for two sky island bumble bees

Abstract Genetic diversity is critical for species’ persistence and for preserving biodiversity. Regions with extreme elevation gradients, including ‘sky island’ systems, are predicted to restrict gene flow owing to dispersal barriers between high-elevation habitat patches (isola...

Paying for Pain: How Healthcare Costs Influence Physical Pain Predictions

ABSTRACT As healthcare costs continue to rise in the United States, consumers increasingly encounter financial burdens that impact their economic well‐being along with their psychological experiences surrounding medical care. This research examines how the pain of paying, a well‐...

Validation Selects Singletons: Auditing an Annotation Error-Detection Procedure Against an Independent Annotator Population

Two-round annotation designs that ask annotators to justify and then validate their labels are used to separate annotation error from legitimate human label variation, but what such rounds discard is rarely audited. We audit the round-2 validity judgments of VariErr NLI against C...

Scattering for the \({1d}\) NLS with Inhomogeneous Nonlinearities

Abstract. We prove large-data scattering in [Formula: see text] for inhomogeneous nonlinear Schrödinger equations in one space dimension for powers [Formula: see text]. We assume the inhomogeneity is nonnegative and repulsive; we additionally require decay at infinity in the case...

Three Strategies to Strengthen Therapist Follow-Through in Therapy Sessions: Examination of Accountability in Clinical Supervision

Abstract Clinical supervision is a natural opportunity for promoting therapist use of clinical practices supported by research in community mental health services. However, the research on thespecific strategies in supervision that are likely to have a positive impact is limited....

Quantifying CAHOOTS: Measuring a mobile crisis response program’s impact on police response through call diversion and prevention

Mobile Crisis Response Programs (MCRPs) have emerged as alternatives to police for emergency mental and behavioral health calls, yet their effectiveness in diverting calls from police remains contested. CAHOOTS (Crisis Assistance Helping Out On The Streets), the United States’ lo...

At-home limbic-targeted transcranial electrical stimulation during sleep: a feasibility study in healthy adults

Deep sleep (N3) and rapid eye movement (REM) sleep are critical for memory and emotional regulation and are often disrupted in neurological and psychiatric disorders. Recent work suggests that focal limbic slow oscillations may provide a target for transcranial electrical stimula...

Validity and Reliability of the Sociocultural Attitudes Towards Appearance Questionnaire in Adult Mexican Women

ABSTRACT Objective This study aimed to validate the Sociocultural Attitudes Towards Appearance Questionnaire‐4 (SATAQ‐4) in Mexican women, evaluating its factor structure, internal consistency, temporal stability, convergent validity, and measurement invariance in women with and...
