Interfacial structure and chain anisotropy in PVC/SiO 2 nanocomposites: a layer-resolved static analysis by molecular dynamics

Diego Jaramillo-Cano · Diego Luis González-Cabrera · Manuel Camargo

Abstract The interphase formed between polymers and inorganic nanofillers plays a central role in determining the macroscopic properties of polymer nanocomposites, yet its molecular structure remains difficult to characterise in a systematic and physically meaningful way. In this work, we investigate the interfacial st...

SPARK-AMR: An autonomous mobile robotic platform for collaborative human-robot intralogistics in small and medium-sized enterprises: Four-layer hardware architecture, localization using extended Kalman filter and industrial validation

Joseph Javier Sánchez Acuña

Abstract Background — Autonomous Mobile Robots (AMRs) have fundamentally transformed intralogistics operations in large distribution centres; however, their acquisition cost structurally excludes Small and Medium-Sized Enterprises (SMEs) — a phenomenon termed the Automation Death Valley. In Colombia, SMEs represent 96....

Do Nursing Students' Personality Traits Affect Medical Error Attitudes and Tendencies?

Sevda Karakaş · Hatice Acar Bektaş · Rojjin Mamuk

The purpose of this study is to investigate whether nursing students’ personality traits affect medical error attitudes and tendencies. This descriptive, cross-sectional, and correlational study was conducted with 343 nursing students enrolled in three universities. Since the rate of malpractice is relatively high in g...

Molecular phylogenetics and insights into interspecific hybridization in Kohleria (Gesneriaceae) from the Central Andes of Colombia

Juan Quintero Hortúa · Jorge Mario Londoño Caicedo · Andres J. Cortés · Alejandro Zuluaga · y 3 más

Kohleria is a Neotropical genus comprising 23 species which taxonomy has historically been intrincate by extensive phenotypic plasticity and frequent interspecific hybridization. This study aimed to molecularly characterize Kohleria species from the Central Andes of Colombia and evaluate potential interspecific hybridi...

Distribution of medium and large terrestrial mammals in the Colombian Caribbean region: integrating environmental heterogeneity into species distributions models

Julio J. Chacón-Pacheco · J. Nicolas Urbina Cardona · Jairo Pérez-Torres · Octavio Rojas-Soto

Aim: To evaluate how climatic variables, environmental heterogeneity, and their combination influence Species Distribution Models (SDMs) of medium- and large-bodied terrestrial mammals in a human-modified tropical landscape, comparing forest-dependent and non-dependent species and assessing the relationship between env...

Ruta Rosa de Cáncer de Seno (RRCS): una propuesta para la navegación de pacientes oncológicos en Montería, Córdoba

Natalia Tabares-Acosta · Camilo Villegas-Pulido · Isabella Vallejo-Caiza · Saray Fernanda Saavedra-Velandia · y 2 más

Breast cancer remains a leading cause of mortality and morbidity among women in Colombia, a situation exacerbated in regions like Montería, Córdoba, where social, economic, geographic, and administrative limitations persist, affecting access to and continuity of cancer care. The objective of this study was to identify...

Case Report: A novel 3D-printed dual-matrix system for guided fabrication of indirect anterior composite veneers

Federico Wirz · Maximiliano Cáceres · Isidora Arnés · Gerardo Durán Ojeda

Resin composite veneers are widely used for esthetic rehabilitation of anterior teeth, offering a minimally invasive approach to restore tooth form and harmony. In indirect techniques, a digital diagnostic wax-up can define the final morphology; however, its accurate transfer to the clinical setting remains challenging...

Studies on Pygmy Grasshoppers: Bogotatettix Cadena‐Castañeda, García‐García & Tavares, gen. nov. (Orthoptera: Tetrigidae), a New Genus From the High Andean Forests and Páramos

Oscar J. Cadena‐Castañeda · Alexander García‐García · Ronald Fernando Quintana‐Arias · Juan Pablo Prias‐Sarmiento · y 1 más

ABSTRACT In this contribution to the study of pygmy grasshoppers, a new genus is described, which inhabits the high Andean forests and páramos surrounding the Bogotá Savannah, Colombia. Bogotattetix Cadena‐Castañeda, García‐García & Tavares, gen. nov. includes a new species, Bogotattetix chingazaensis Cadena‐Castañeda,...

MS-SENet: A Multi-Scale Squeeze–Excitation Network for Deep-Learning-Based Automatic Modulation Classification in Cognitive Radio Systems

Evelio Astaiza Hoyos · Héctor Fabio Bermúdez-Orozco · Nasly Cristina Rodriguez-Idrobo

Automatic modulation classification (AMC) is a critical enabler of cognitive radio (CR) systems, allowing secondary users to identify primary user modulation schemes and adapt transmission parameters in real time. Traditional AMC approaches, based on likelihood functions or hand-crafted features, suffer from degraded p...
