Equilibrium halo solutions of the Gross–Pitaevskii–Poisson system: the role of the particle number

Abstract We investigate stationary halo-like solutions of the Gross–Pitaevskii–Poisson (GPP) system, which describes self-gravitating Bose–Einstein condensates with repulsive self-interactions, as a model for dark matter. We retain the boson mass $$m_\phi $$ m ϕ , the scattering...

A q-deformed deterministic gradient framework generalizing affine projection adaptive filters

Purpose This work proposes a q-deformed deterministic gradient framework that generalizes affine projection adaptive filters by embedding a deformation of the classical gradient operator into a fully deterministic formulation. Design/methodology/approach By embedding the q-gradie...

Management of metastatic spinal disease in low- and middle-income countries: an international survey of practices and challenges in Latin America

Spinal metastases impose urgent diagnostic and therapeutic demands; however, evidence from low- and middle-income countries (LMICs) in Latin America is sparse. We aimed to characterize real-world practices, access gaps, and priorities to in-form context-adapted guidelines. We con...

Translation Landscape of Corneal Endothelial Tissue Engineering: A Scoping Review

Background Corneal endothelial dysfunction is a leading cause of global blindness. The main treatment is full keratoplasty, for which access is limited due to the worldwide shortage of tissue donors. Corneal tissue engineering has shown significant progress, yet there are still c...

Optic nerve avulsion and central retinal artery occlusion after penetrating orbital injury

Purpose: To highlight a rare mechanism of optic nerve avulsion and central retinal artery occlusion secondary to penetrating orbital trauma, and to review the clinical and diagnostic findings that facilitate accurate identification of this uncommon pathology. Methods: The patient...

Update on the Physiopathology of Keratoconus

Keratoconus (KC) is a progressive corneal ectasia characterized by stromal thinning, steepening, and biomechanical instability. Although historically considered primarily a structural disorder, current evidence supports a multifactorial pathogenesis involving complex interactions...

Cooperative multi-agent reinforcement learning with entangled state representations and copula-based action coordination for urban navigation

Abstract Cooperative multi-agent reinforcement learning (MARL) enables autonomous agents to coordinate in complex spatial environments. This study proposes a MARL framework for goal-directed navigation that integrates entangled state embeddings, copula-based joint action transfor...

Optimizing Injection Molding Parameters for Enhanced Properties in Glass Fiber-Reinforced Polypropylene

The mechanical properties of fiber-reinforced polymer matrix composites are largely influenced by the characteristics of their constituents, including the matrix and fibers. During injection molding, various process parameters such as thermal and pressure variations play a critic...

Within-family effect of ancestry on complex traits in a Mexican population

Abstract Human populations differ in disease prevalence and phenotypes, but the extent to which differences are caused by genetic factors is unknown for most complex traits. Comparing phenotypic means across populations is confounded by environmental differences and using polygen...

The Modern Urology Pipeline: Career Trajectories of Recent Residency Graduates

INTRODUCTION: Urology residency graduates face a pivotal transition when deciding on fellowship training and eventual practice setting. While traditionally a fellowship was a gateway to academia, recent trends reveal increasing pursuit due to job market concerns and perceived gap...

Agile framework for managing capstone projects involving university-business cooperation

University–Business Cooperation in capstone projects often faces significant managerial tensions due to misaligned expectations and conflicting timelines. This study addresses the challenge of industrial partner satisfaction by developing and assessing a coordination framework th...

Whole genome sequencing of 1427 Mexican individuals from the oriGen cohort

Latin American populations remain underrepresented in genomic research. To help address this, we present an analysis of high-coverage whole-genome data from 1481 volunteers recruited as part of the oriGen Project. We identify over 47.2 million SNVs and 8.1 million short indels, i...

Validation of the MODEL UR and socio-motivated resilience for disaster risk governance in the Monterrey metropolitan area

To investigate the relationship between urban resilience and disaster risk governance in the Monterrey Metropolitan Area (MMA), Mexico, a theoretical model was developed and validated. The study examined how governance processes, social cohesion, and institutional capabilities su...

Thinner femoral cortical thickness in children with knee hemophilic arthropathy

A cross-sectional study was performed to compare the cortical femoral shaft between the leg with knee hemophilic arthropathy and the contralateral leg. Children with hemophilic arthropathy were included. Joint evaluation was made using the Hemophilia Joint Health Score 2.1 (HJHS...

Parent Perspectives on Adolescent Gender-Based Violence as a Public Health Issue in Medellín, Colombia: A Qualitative Study

Introduction Gender-based violence (GBV) is a major public health concern affecting adolescents across Latin America. Yet, little is known about how parents, as key figures in adolescents’ social environments, understand these risks. This study explored parental perspectives on a...

Shared CI-linked bioenergetic dysfunction and muscle-specific lipid/redox stress in skeletal muscle of male cardiometabolic HFpEF mice

Exercise intolerance is a hallmark of heart failure with preserved ejection fraction (HFpEF), particularly in its cardiometabolic form, where obesity, metabolic dysfunction, and impaired peripheral oxygen utilization contribute to functional limitation. Skeletal muscle mitochondr...

How does intercalation reshape layered structures? A first-principles study of sodium insertion in layered potassium birnessite

This work presents a first-principles study of the sodium intercalation process in a layered potassium birnessite (a layered manganese dioxide, δ-MnO2) using hybrid-level density functional theory. Understanding the intercalation processes of δ-MnO2 is a vital step in advancing i...

Implementing digital health transformation policies in Latin America: insights from four national case studies

Abstract Digital health transformation (DHT) policies can improve the performance of health systems. However, there are few empirical studies on how these policies are implemented in practice. This article examines four national cases of implementing DHT policies in the Latin Ame...

A Decay Rate for Steady Guaranteed In‐Control Performance in Statistical Process Control Models With Cautious Parameter Learning

ABSTRACT Control charts with parameter estimates from small Phase I samples are at risk of providing inaccurate signals due to poor model fit. In turn, Guaranteed In‐Control Performance (GICP) approaches were introduced to account for the resulting variability in the conditional...

How Norms Depend on the Presence and Status of Observers: The Relational Contingency of Everyday Behaviors in 90 Societies

Norms are fundamental to social life, but basic questions about how they are affected by social context remain. Specifically, how do normative constraints depend on the presence and status of observers, and how do such relational contingencies vary across cultures? Using data fro...
