Distributed Antenna Array and RIS-Assisted Planning Framework for Intelligent Coverage Optimization in B5G/6G Cell-Free Massive MIMO

Valdemar Farre · José Vega-Sánchez · Alejandro Cama-Pinto · Victor Garzón Pacheco · y 2 más

The transition to Beyond fifth generation of wireless networks (B5G) and sixth generation of wireless networks (6G) exposes the severe interference and coverage limitations of conventional cell-centric architectures. To overcome these bottlenecks, this paper presents a scalable four-layer radio network planning framewo...

Effective temperatures estimation of low-mass stars and identification of T Tauri stars in LAMOST DR10 using machine learning

C D Millan-Valderrama · J Hernandez · B Sabogal · J Muñoz

ABSTRACT We present effective temperature ($T_{\mathrm{ eff}}$) estimates of low-mass stars and T Tauri stars (TTS) candidate detections derived from automated spectroscopic measurements and low-complexity machine-learning models applied to the LAMOST DR10 V2 survey. Equivalent widths of key diagnostic spectral feature...

Search for planetary-mass ultracompact binaries using data from the first part of the LIGO–Virgo–KAGRA fourth observing run

Abac, A. G. · Abouelfettouh, I. · Acernese, F. · Ackley, K. · y 196 más

We present a search for gravitational waves from inspiraling, planetary-mass ultracompact binaries using data from the first part of the fourth observing run of LIGO, Virgo, and KAGRA. Finding no evidence of such systems, we determine the maximum distance reach for such objects and their merger rate densities. Then, we...

Neuroprotective Potential of Sesamum indicum in a Multifactorial In Vitro Neuron–Astrocyte System Exposed to Chronic Stress Mediators

Viviana Soto-Mercado · María Paulina Arias-Loaiza · Miguel Mendivil-Perez

Chronic stress is increasingly recognized as a major contributor to Alzheimer’s disease (AD)-related neurodegeneration through mechanisms involving neuroinflammation, oxidative stress, mitochondrial dysfunction, excitotoxicity, and amyloidogenic processing. Here, we investigated the neuroprotective effects of Sesamum i...

Replication package for the article Flexibility-Oriented Multi-Period Optimal Power Flow for Smart Transformer-Based Meshed Hybrid AC/DC Microgrids. The package contains the complete optimization model, a per-layer certification suite, the certified result datasets, and the scripts that generate every figure in the art...

Bile Microbiology and Risk Factors Associated with Antibiotic Resistance Patterns in Patients Taken to Laparoscopic Cholecystectomy: A Prospective Cohort Study

Isabella Van-Londoño · Camilo Ramírez-Giraldo · Samir Moreno-Martinez · Carlos Rodriguez-Barbosa · y 4 más

Objectives: To evaluate bile culture microbiology and factors associated with resistance patterns in patients taken to laparoscopic cholecystectomy to better guide empiric antibiotic therapy. Methods: Prospective cohort study with a logistic regression model in a middle-income public hospital network of two institution...

Clinical and microbiological epidemiology of Candida infections in a high-complexity hospital in Tolima, Colombia (2014–2024)

Rafael A. Ramírez-Trujillo · Paula Carvajal-Hernández · Ángel González

Background Candida spp. infections are an increasing challenge in high-complexity hospitals, yet epidemiological data remain scarce in underrepresented in Colombian regions such as Tolima. Methods We conducted a retrospective observational study in a high-complexity hospital in Ibagué (Tolima, Colombia) from 2014 to 20...

The historical evolution of dynamic capabilities: From resource reconfiguration to strategic orchestration

Matteo Cristofaro · Pier Luigi Giardino · David J. Teece

Purpose The study reconstructs the historical evolution of research on dynamic capabilities (DCs), perhaps the most influential framework in contemporary strategic management for explaining how firms achieve and sustain competitive advantage. By examining its development over nearly three decades, the study aims to exp...
