Con este fin, se implementó u...

An Explicit Diffusion Operator for High-Order Entropy-Stable Schemes in an Augmented 1D Blood Flow Model

Carlos A. Vega · Andrés Guerra

We propose an entropy-stable numerical scheme for an augmented one-dimensional blood flow model by constructing an explicit diffusion operator independent of the reconstruction method used for the scaled entropy variables. The diffusion term plays an important role in entropy-stable schemes, i.e., schemes satisfying a...

Directional Asymmetry in Edge‐Based Spatial Models via a Skew–Normal Prior

Danna L. Cruz‐Reyes · Renato M. Assunção · Reinaldo B. Arellano‐Valle · Rosangela H. Loschi

ABSTRACT We introduce a skewed edge‐based spatial prior, named RENeGe‐sk, that extends the Gaussian RENeGe framework by incorporating directional asymmetry through a skew–normal distribution. Skewness is defined on the edge graph and propagated to the node space, aligning asymmetric behavior with transitions across nei...

Code for a Temporal Spectral Analysis of Late-Time Error in a Physics-Informed Neural Network Solution of the One-Dimensional Advection-Diffusion Equation

Díaz-León, David

Persistent late-time variation can remain in physics-informed neural network (PINN) solutions after the governing transient has effectively decayed, while conventional error norms do not reveal whether this variation has a systematic temporal-frequency structure. This study develops an offline temporal-spectral diagnos...

El Robux como hecho político: comunidad imaginada y autogobierno cotidiano en la economía simbólica de Roblox

Saldarriaga, Kathy Elizabeth

Este trabajo analiza la construcción simbólica y económica del Robux, la moneda virtual de la plataforma Roblox, y sus efectos en las dinámicas de socialización, estatus y autoridad entre niñas, niños y adolescentes en Medellín, Colombia. A partir de un enfoque etnográfico digital y la aplicación de encuestas triangula...

Strawberry micropropagation simplifies endomicrobiome and highlights potential for in vitro biotization with beneficial rhizobacteria

A. M. G. Sepúlveda · E. da Conceição Jesus · Y. C. Molina · V. H. Buttrós · y 3 más

Abstract Strawberry micropropagation produces uniform, disease‐free planting material. However, repeated in vitro subculturing can simplify the endophytic microbiome, reducing plant vigour and acclimatization success. This study investigated the impact of successive in vitro generations on the endomicrobiome of Fragari...

Decoding Wolffia : A Predictive Model for Duckweed Growth and Nutrient Uptake for Resource Recovery from Wastewater in Tropical Countries

Johan Andres Pasos-Panqueva · Anie Yulistyorini · Alison Baker · Miller Alonso Camargo-Valero

Abstract Duckweed-based wastewater treatment systems have attracted increasing attention for sustainable water pollution control, yet predictive tools to optimize their operation under real-world conditions remain limited. Here, we develop and validate a temperature- and nutrient-dependent kinetic model for the duckwee...

Benchmarking Supervised Classifiers for Concurrent Multidomain Dropout-Intention Attributions in Higher Education: Evidence from a Colombian Public University

Marieth Agnes Guillen-García · Osnamir Elias Bru-Cordero · Cristian David Correa-Álvarez

Student retention analytics often treats withdrawal as a single outcome, although students may attribute dropout intention to personal, socioeconomic, and academic pressures simultaneously. We benchmarked nine supervised classifiers for identifying a concurrent three-domain attribution profile in a cross-sectional surv...
