Stefan-Boltzmann law in rainbow space-time

Bhagya R · E. Harikumar

Abstract We investigate the modification of the Stefan-Boltzmann law in the space-time whose geometry is energy-dependent. From the energy-momentum tensor of the electromagnetic field in rainbow space-time, we obtain the energy density of the isotropic radiation, valid up to the first order in the rainbow parameters. U...

Hybrid self-compacting concrete incorporating ceramic waste and recycled aggregates

William G. Valencia-Saavedra · Katerin V. Muñoz-Leiton · Mayra A. Pabón-Urbano · Ruby Mejía de Gutiérrez

Abstract Self-compacting concrete offers significant advantages in terms of ease of placement, reduced construction time, and improved quality control. However, its production typically requires higher amounts of cement and chemical admixtures. At the same time, the valorisation of construction and demolition waste has...

El agenciamiento crítico en la enseñanza de las matemáticas en educación primaria

Marybel Capera-Tovar · María Inés Menjura-Escobar · Francisco Javier Camelo-Bustos

This article analyzes the transformation trajectories of mathematics teaching practices in primary education when teachers manage processes of critical agency in the classroom. The study, qualitative and interpretive in nature, was conducted with seven in-service primary school teachers within the framework of a doctor...

Shapley Value for A Differential Game of Monetary and Fiscal Economic Policy

Andrés F. Russi

This paper implements a dynamically stable cooperative mechanism for allocating economic-policy costs between fiscal and monetary authorities in the context of public debt stabilization. The mechanism is implemented in the debt-stabilization game proposed by Tabellini [1986] [Money, debt and deficits in a dynamic game,...

Functional connectivity methods for detecting seizure onset zone in focal epilepsy: an approach through temporal graphs and community detection

Pablo A. Osorio Marulanda · Juan D. Martínez-Vargas · Lina M. Sepúlveda-Cano · Alejandro Peña

Focal epilepsy, a prevalent neurological disease with seizures from localized brain regions, poses significant diagnostic and treatment challenges. Precise seizure onset zone (SOZ) localization is crucial for surgery in drug-refractory cases. However, traditional static or time-averaged functional connectivity (FC) mod...
