Racial microaggressions in prenatal care settings and perceived quality of prenatal care among Black/African American women

In the United States, Black/African American (AA) women face significant health disparities, including higher rates of Adverse Pregnancy Outcomes (APOs). This is despite increased utilization of prenatal care (PNC) over time, which is a critical intervention for identifying and m...

Prevention Portfolios, Residual Mechanisms, and Cross-Level Fit

Complex crime problems are frequently addressed through combinations of interventions. Yet the presence of several interventions does not establish that they form a coherent prevention portfolio, cover the relevant crime process, operate compatibly, or support claims of sufficien...

No gender differences in predictive processing

Abstract Statistical learning, defined as the implicit extraction of environmental regularities, is considered a fundamental cognitive mechanism that supports predictive processing across individuals, domains, and species. However, whether it is modulated by gender remains unclea...

From Fragmented DMD Management Toward Digitally Enabled Circularity: A Conceptual Operations Framework for Durable Medical Devices

Durable medical devices (DMD) are essential healthcare assets, yet their management in public hospitals is constrained by fragmentation, limited traceability, reactive maintenance, and weak lifecycle integration. This study proposes a framework for digitally enabled, sustainable,...

Longitudinal vibrations of bi-directionally functionally graded microbars with deformable boundaries

Abstract The present research focuses on the longitudinal vibration analysis of a microbar resting on an elastic foundation, incorporating deformable (spring-based) boundary conditions. The material is modeled as functionally graded in two spatial directions. The governing equati...

Macroscopic Quantum Hydrodynamics: Transitioning to Deterministic Continuum Mechanics and the Scale-Invariance of the Superfluid Vacuum

Macroscopic Quantum Hydrodynamics: Transitioning to Deterministic Continuum Mechanics and the Scale-Invariance of the Superfluid Vacuum This monograph provides a deterministic, hydrodynamic foundation for Quantum Mechanics, replacing the probabilistic abstractions of the Copenhag...

Explainable Surrogate-Based Knowledge Extraction from DEM Simulations: Cross-System Algorithm Selection and SHAP Interpretability for Granular Material Handling Optimization

Extracting transferable design knowledge from Discrete Element Method (DEM) simulations remains challenging in granular material handling. We develop an explainable surrogate framework for two solar-panel-recycling subsystems: a silo discharge system (outlet width 42–111 mm; hopp...

A Sequential Gut–Pancreas–Liver In Vitro Model to Evaluate the Multi-Target Metabolic Effects of a Nutraceutical Formulation in MASLD-Related Conditions

Background/Objectives: Metabolically dysregulated-associated steatotic liver disease (MASLD) is a complex, multifactorial disorder characterised by hepatic lipid accumulation, insulin resistance, oxidative stress, and dysfunction of the gut–liver axis. Given its intricate pathoph...

Phi‑Driven 8‑Dimensional Temporal Loop via Dual‑Phase E8 Braiding — E8 Intelligence Research

Combining the 132 Hz phi‑phase lock with a second harmonic at 396 Hz creates a coupled braid of 240 root vectors that closes a closed‑timelike loop across the E8 manifold. This loop encodes a self‑referential topological invariant that predicts a new class of resonance‑stabilized...

Factors affecting gait symmetry in unilateral transtibial prosthesis users: Surface, speed, and slope

Background: In individuals with lower extremity amputation, a certain degree of gait asymmetry is biomechanically unavoidable and has been associated with reduced energy efficiency, secondary musculoskeletal complications, and diminished quality of life. The aim of this study was...

Electrodynamics of Lattice Vacuum Defects: The Topological Origin of Drift-Induced Hole Generation

Electrodynamics of Lattice Vacuum Defects: The Topological Origin of Drift-Induced Hole Generation Abstract & Main Contents This manuscript presents a topological vacuum-defect model of solid-state hole mechanics, providing a deterministic physical explanation for effective mass,...

Development of a proposed guide to identify, screen and appraise self-report and device-based measures of habitual physical activity in systematic reviews: a methodological protocol

Habitual physical activity (PA) is a fundamental determinant of health, yet its assessment and reporting vary substantially across research studies, creating persistent challenges for evidence synthesis. Systematic reviews that aim to synthesise habitual PA outcomes are frequentl...

From Crime Problems to Crime-Process Profiles

Crime-prevention analysis commonly begins with named problems such as youth violence, gang recruitment, hot spots, recidivism, drug markets, or repeat victimisation. Such labels are useful for recognition and administration, but they do not by themselves identify the mechanisms t...

Mitogenome-Informed Metabarcoding for Non-Invasive Identification of Sympatric Flamingos in Northern Chile

The Chilean flamingo (Phoenicopterus chilensis) is a widely distributed South American species inhabiting diverse wetland ecosystems from Ecuador and Peru south to Chile and Argentina, and east to Brazil, Uruguay, and Paraguay, ranging from sea level to high-altitude Andean salar...

A Thematic Analysis Exploring Cultural Elements of Dance Movement Therapy in India

INTRODUCTION: India has a long, rich, and diverse culture in the arts, and dance and movement is one of the vital elements. This impacts the practice of dance movement therapy (DMT) in India. Research done on DMT mostly highlights the Western perspective. There is insufficient re...

A Microseismic Energy Field Distribution Prediction Method Guided by Geological Structure Priors

Existing microseismic prediction methods commonly incorporate domain prior knowledge as ordinary input features, which makes it difficult to fully exploit its structural constraints and physical implications. To address this limitation, this study proposes a geological-structure-...

Motion-State-Aware Adaptive Step-Length Smartphone PDR for GPS-Denied Pedestrian Localization

Smartphone-based pedestrian dead reckoning (PDR) provides an infrastructure-free solution for two-dimensional (2D) planar localization in GPS-denied environments, but its open-loop nature makes it sensitive to accumulated step-length and heading errors. These errors grow when ped...

Knocking on Heaven's Door: Faith, Ecstasy, and Crossing Over in Zola's Le Rêve ( The Dream )

Abstract: When Angélique, the protagonist of Émile Zola's Le Rêve (1888), expires at the cathedral entrance just moments after her wedding, the novel's central theme comes to fruition: spiritual fulfillment cannot be expressed in physical terms. Angélique's fiery and unstable Rou...

Soilless farming system design impacts the diversity and composition of microbiota

ABSTRACT Controlled environment agriculture (CEA), including soilless farming systems, is expanding to improve food security and resource efficiency. However, little is known about how different soilless farming system designs influence microbial populations that may be relevant...
