Five-Year Cost-Effectiveness Analysis of Endoscopic Third Ventriculostomy With Choroid Plexus Cauterization Versus Ventriculoperitoneal Shunting in Postinfectious Hydrocephalus in a Low-Income Setting

BACKGROUND AND OBJECTIVES: For over 2 decades, an emerging body of data has established endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) as a viable option in the treatment of postinfectious hydrocephalus (PIH) in low-resource settings with similar out...

Pediatricians’ Perspectives on Routine Hospital Discharge Follow-Ups: A Qualitative Study

BACKGROUND: There is considerable practice variation among pediatric hospitalists in how they recommend hospital discharge follow-up visits for pediatric patients hospitalized with common, self-limiting, acute illnesses. Literature lacks evaluation of the preferences of primary c...

ReSounding the Lost Apple: Operation Pedro Pan and Communicating Grief through Musical Performance

Abstract From December 1960 to October 1962, over 14,000 unaccompanied Cuban minors arrived in the United States as part of a covert airlift known as Operation Pedro Pan (OPP). Like most Cold War initiatives, OPP became entrenched in polarizing political rhetoric that obscured th...

Integrated Mental Health Care for Perinatal Anxiety and Depression in the United States: A Systematic Review

OBJECTIVE: The ongoing maternal mental health crisis highlights the urgent need to improve access to integrated behavioral health care within medical settings for perinatal individuals. This review aimed to synthesize the current evidence on integrated models of care in the Unite...

Photoluminescent amorphous silicon microspheres with intrinsic whispering-gallery-mode coupling and waveguide integration

Abstract On-chip silicon light sources are highly desirable for integrated photonics but remain challenging due to silicon’s indirect bandgap and low radiative efficiency. Amorphous silicon supports photoluminescence via band-tail states, yet lacks scalable cavity platforms for e...

Interaction of internal waves impinging upon stratified turbulence

In the ocean, internal wave beams are generated by the barotropic tide passing over steep topography. Observations suggest that these wave beams are dissipated as they propagate into the upper ocean. This differs from idealised numerical simulations of wave propagation, in which...

Influence Functions for Data Attribution in System Identification and LQR Control

Abstract When a controller is designed from an identified model, its performance ultimately depends on the trajectories used for identification, yet pinpointing which ones help or hurt remains an open problem. We bring influence functions, a data-attribution tool from machine lea...

A multi-site benchmarking framework for scalable extraction of geriatric care constructs from electronic health records

Current Natural Language Processing (NLP) algorithms for detecting geriatric conditions are largely limited to domain-specific models that fail to capture the interdependent, multidimensional nature of comprehensive geriatric assessment. This study aimed to develop and evaluate a...

Shape Control of Deformable Structures Using Iterative Multi-Modal Density Steering

Abstract We present an iterative algorithm for shape control of deformable structures based on multi-modal density steering methods. In our approach, the dynamics of a deformable structure are described by a mass-spring-damper (MSD) network, and its shape is represented by a mult...

Cultural Stress, Psychopathology, and Well-Being Among Latinos: A Two Continua Model Approach

Abstract Latinos in the USA experience myriad cultural stressors that increase their risk for experiencing psychopathology. Whereas most Latino-focused research has conceptualized psychopathology and well-being as existing on opposite ends of the same continuum, the Two Continua...

National Outcomes of Sepsis in Publicly Insured Children: 2021–2023

OBJECTIVE To identify incidence and factors associated with sepsis mortality. METHODS We conducted a cohort study of all US publicly insured children younger than age 19 years hospitalized with a diagnosis code–based definition of sepsis in 2021–2023 using the Transformed Medicai...

Phase Variance as a Seismic Quality-Control Attribute

Seismic sensors deployed in land acquisition record wavefields that are strongly distorted by near-surface heterogeneity, which introduces trace-specific, frequency-dependent phase perturbations that persist even after advanced time processing. These distortions are more pronounc...

Executive Discretion in the Zone of Twilight: War Powers Amidst Congressional Silence

This article recovers the constitutional thought of Alexander Hamilton, John Marshall, and others to provide a limited theory of presidential war powers. Contemporary legal understandings of war powers follow Justice Robert Jackson’s canonical framework in Youngstown Sheet & Tube...

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

Abstract Drought is an increasingly important driver of tree mortality, but its long-term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communiti...

Directional Dependence of Gas Dispersion in Carbonates and Sandstones

Abstract This study investigates the directional dependence of gas dispersion in porous media with varying lithology and macroscopic heterogeneity. Eight rock samples, including three carbonates and five sandstones, were examined through CH4–CO2 core-flooding experiments at 300 p...

Star cluster formation from turbulent clumps. V. Stellar clustering around massive stars

Abstract Massive stars (≥8 M⊙) are known to have high degrees of multiplicity, e.g., with about 60% in triples or higher-order multiples. Such high levels of multiplicity may arise during formation (primary multiplicity) or through dynamical processing of already formed stars in...

Noisy Listening: Climate Change as Vibratory Milieu

“Noisy listening” explores resonances between sound and climate change by listening to and thinking with noise, being in noise as conditions shift more or less dramatically, taking form and becoming palpable or legible, or remaining indeterminate. Noise as a way of knowing is at...

Viscous Destabilization for Large Shocks of Conservation Laws

Abstract. The recent theory of [Formula: see text]contraction with shifts provides [Formula: see text]-stability for shock waves of one-dimensional hyperbolic systems of conservation laws. The theory has been established at the inviscid level uniformly in the shock amplitude and...

AnExplainable AI Engineering Framework for Claims-Only First-Stage Provider Audit Triage Using SHAP-Guided Hybrid Retrieval-Augmented Generation

This study proposes an explainable artificial intelligence (XAI) engineering workflow for provider-level healthcare claim audit prioritization using SHAP-guided hybrid retrieval-augmented generation (RAG). The framework integrates provider-level claim aggregation, tree-based risk...

Blue-sky thinking about pronunciation research and teaching

Abstract In the fall of 2024, Ron Thomson and Tracey Derwing invited 15 pronunciation scholars representing several subspecialties to participate in a full-day symposium to discuss directions for pronunciation research. To prepare for the symposium, held in conjunction with the P...
