A large-scale Bayesian validation of FIDBV2 and FIDBV3 methods for adult age-at-death estimation using root dentin translucency in single-rooted teeth

Leandro H. Luna · Roberto C. Parra · Gonzalo Garizoain · Douglas H. Ubelaker · y 32 más

Statistical calibration of the results in adult age-at-death estimation is a fundamental yet challenging task in forensic anthropology and bioarchaeology. This study conducts a large-scale Bayesian validation of two probabilistic models for adult dental age-at-death estimation: the established FIDBv2, using root dentin...

Evolution of withanolide biosynthesis in nightshades

Santiago Perez · Saleh Alseekh · Sofía Rojas Contreras · Rocío Deanna · y 4 más

Abstract Withanolides are a diverse class of defensive metabolites produced by multiple clades within the nightshade family (Solanaceae). To evaluate whether withanolide biosynthesis originated independently across these lineages, we investigated the evolutionary history of a withanolide biosynthetic gene cluster (WBC)...

A study of Retardation Models for Phenomenological Interactions in Hadronic Physics

M. De Sanctis

A study of retardation models for the hadronic quark interaction is performed starting from a coordinate-space calculation that elaborates a classical electrodynamics procedure. The possibility of constructing a corresponding quantum operator is critically analyzed also performing some numerical matrix element calculat...

Unheard voices in oral health: the mouth, oral health, and barriers to accessing dental care in disadvantaged communities and Venezuelan migrants in Bogotá

Luis Alberto Sánchez–Alfaro · María Kamila Navarro-Ramírez · Roger Keller Celeste · Richard G. Watt · y 8 más

Abstract Background Research on barriers to oral healthcare in Colombia shows that access is restricted by the uneven geographical distribution of dental providers and high out-of-pocket costs for patients, particularly affecting poor populations, residents of marginalised areas, and people in vulnerable situations. Th...

A Matheuristic Optimization Approach for Simultaneous Feeder Routing and Conductor Sizing in Unbalanced Distribution Networks

Brandon Cortés-Caicedo · Oscar Danilo Montoya · Santiago Bustamante-Mesa

The optimal expansion of unbalanced three-phase distribution networks in non-interconnected zones requires the simultaneous resolution of two highly complex planning decisions: the selection of feeder routes and the sizing of conductors. This problem, formulated as a non-convex mixed-integer nonlinear program (MINLP),...

Integrating BIM and Virtual Reality to Support Decision-Making in the Finishes Selection of Residential Buildings

León, Carlos A. · Sánchez, Omar · Cristancho, Luis A. · Castañeda, Karen

During the purchase or renovation of housing, a limitation exists in the finish design process for construction projects, as buyers cannot switch between various finish options for their apartments. Instead, they must depend on visual graphics or physical samples to imagine the appearance of these finishes in their hom...

Incidencia de trombosis venosa aguda asociada al uso de catéter venoso central de inserción periférica evaluada por ecografía enfocada a la cabecera del paciente en una población de pacientes críticamente enfermos en un hospital de IV nivel de la ciudad de Bogotá, año 2024

Santiago Ausecha, Daniel Ricardo

Introducción: Los catéteres PICC representan una alternativa segura a los catéteres venosos centrales convencionales al disminuir las complicaciones mecánicas de la inserción. No obstante, mantienen un riesgo importante de trombosis e infección asociadas al dispositivo. La ecografía POCUS facilita el diagnóstico tempra...

Adaptación de especies forrajeras arbustivas y arbóreas tropicales en un suelo andisol como fuente alimenticia alternativa para rumiantes en el litoral ecuatoriano

Meza Bone, Gary Alex

The effects of forage species (Tithonia diversifolia, Erythrina poeppigiana, and Cratylia argentea) and cutting ages (30, 45, 60, and 75 days) were evaluated. A completely randomized design with a factorial arrangement was used. Significant differences (P < 0.05) were observed among forage species, cutting ages, and th...

Exploración de un material biocompuesto para la inmovilización de enzimas : diseño, caracterización y evaluación preliminar de su aplicación en procesos industriales

Galvis-Nieto, Juan David

Enzymatic catalysis is an efficient and environmentally friendly tool in industrial processes, yet large-scale application remains limited by issues of stability and reuse. Immobilization offers a solution by enabling recovery and repeated use; however, there is still a gap in the literature regarding evaluations that...
