Experimental Assessment of Human–Structure Interaction in an Urban Pedestrian Footbridge with Multiaxial Dynamic Sensitivity

Bryan Castillo · Angie L. Arango · Johannio Marulanda · Colin Caprani · y 1 más

Recent advances in structural engineering have enabled lightweight and slender footbridges. However, these structures are often susceptible to excessive vibrations induced by pedestrian activities, primarily impacting urban footbridge serviceability. Most studies evaluate human–structure interaction (HSI) uniaxially ba...

Leptomeningeal carcinomatosis in sinonasal NUT carcinoma: a case report and review of intracranial involvement

Rodríguez-Santiago, Francisco Manuel · Sequero López, Silvia · Láinez-Ramos-Bossini, Antonio Jesús

Background Sinonasal NUT carcinoma is a rare and highly aggressive malignancy, frequently diagnosed at advanced stages with poor prognosis. Intracranial spread is uncommon and, to our knowledge, leptomeningeal carcinomatosis has not been previously reported in sinonasal NUT carcinoma. Case description We describe the c...

Stacked reverberation mapping of high-redshift quasars in DESI. I. Feasibility analysis

Rahma Alfarsy · Rebecca E A Canning · Eva-Maria Mueller · Jessica Aguilar · y 48 más

ABSTRACT The broad-line region of quasars has long been probed by reverberation mapping techniques that measure time lags between continuum and broad emission-line variations. Stacked reverberation mapping has been proposed as a less observationally expensive alternative to traditional methods. This ensemble approach a...

Biocomposites Made from Cocos nucifera L. Fibres and Polyhydroxybutyrate (PHB) for Water Treatment Applications

Rodrigo Ortega Toro · Joaquín Hernández-Fernández · Gian Torres-Fernández · Ángel Villabona-Ortiz · y 1 más

Cr(VI) is considered one of the most dangerous pollutants due to its bioaccumulation and toxicity, which has driven the search for sustainable and effective solutions for its removal from wastewater. In this regard, the aim of this research was to develop a material based on cellulose acetate (CA) extracted from Cocos...

Cuando preguntarle bien a la máquina es la principal lección

Beltrán, Gustavo Adolfo

El Semillero LINFA de la Universidad de la Amazonia desarrolló, durante el primer semestre de 2026, una experiencia formativa que combinó programación con Arduino e inteligencia artificial generativa. El proceso avanzó en tres fases: una socialización inicial con 17 integrantes mediante demostraciones de placas y circu...

El Lugar de Llegar a Ser: el espacio pedagógico como agente de la formación (Colección MILC, Tomo V)

cardenas orozco, alvaro

Quinto y último tomo de la Colección MILC (Modelo de Investigación Liberadora y Científica). Sostiene que el espacio no es el escenario neutro donde ocurre el aprendizaje, sino uno de sus agentes: la misma persona se apaga en un aula y florece en un semillero; la misma escuela es una isla o un nodo según decida abrirse...

Beyond dry and fleshy: Hidden developmental and anatomical transitions in Solanaceae fruit evolution

Estefanía Elejalde‐Baena · Santiago Pérez‐Ospina · Natalia Pabón‐Mora

Abstract Premise Classifying fruits based solely on mature morphology can obscure underlying developmental and anatomical diversity. Current fruit types described in Solanaceae inadequately capture the complexity of fruit evolution within the family. Methods We compared the anatomy of different fruit developmental stag...

Neuropsychological profiles in long-term schizophrenia: A cluster analysis

Maria del Carmen Caballero-Guzmán · Laura Teresa Rodríguez Hernández · Raquel Tierno Patiño · Juan José Fernández Muñoz

This study examines neurocognitive heterogeneity in a large, predominantly chronic and institutionalized sample of individuals with schizophrenia (N = 184). Using hierarchical and iterative clustering on composite neuropsychological scores, four distinct cognitive profiles emerged: Severe Cognitive Impairment, Cognitiv...

Fungal diagnostics and antifungal drug access in Latin America and the Caribbean: an ESCMID EFISG multinational survey

Alessandro C. Pasqualotto · Indira Berrio · Bryan Ortiz · Julio Maquera-Afaray · y 13 más

Abstract Invasive fungal diseases (IFD) pose a major health challenge in Latin America and the Caribbean (LAC), particularly in vulnerable populations. A cross-sectional, survey is distributed between April 2023 and May 2025 to institutions involved in IFD diagnosis or care across LAC. The questionnaire evaluates diagn...
