Torsional extensions of the BTZ black hole with gravitating spinors

P. D. Alvarez · J. Ortiz · J. Zanelli

Abstract We construct exact analytic solutions for a supersymmetric Chern–Simons theory with matter fields in the adjoint representation (unconventional supersymmetry). The configurations correspond to gravitating spinor fields on BTZ geometries with torsion. Although the spinor profiles exhibit divergent behavior near...

Learning Automation in Higher Education: Evaluating the Use of Language Models from an Artificial Intelligence and Bioethics Perspective

Jeniffer Katherine Miranda Moreira · Mariana Martinez · Juan Miguel Guerrero Orbegozo · Fermín Carreño Meléndez

The automation of learning in higher education using language models constitutes a significant transformation in contemporary ways of teaching, learning and assessing. The objective of this study was to evaluate the use of language models in university learning automation processes from an integrated perspective of art...

Exploratory modeling of the influence of fermentation on coffee silverskin spectral fingerprints using R-based statistical tools and FTIR data

Collazos-Escobar, Gentil Andres · Ramón Ossa, Anyi Lorena · Medina Orjuela, Maria Elena · Bahamón-Monje, Andrés F. · y 1 más

This dataset contains Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR) spectral data of coffee silverskin obtained from specialty coffees processed under wet and semi-wet postharvest treatments at different temperatures and fermentation times. Raw spectra is provided together with R scrip...

Enforcing environmental law in the Amazon

Mark Ungar · Juan Corredor‐Garcia

Abstract This article identifies the underlying obstacles to enforcement of laws against environmental crimes such as illegal logging, mining and ranching. With four departments (provinces) from Colombia as case studies, it assesses enforcement of the country's main environmental law, Law 2111, which is one of Latin Am...

A new error bound for nonzero initial conditions in linear dynamical systems

Adnan Daraghmeh · Álvaro H. Salas S. · Arvind Kumar Prajapati

Balanced truncation is one of the most widely used techniques for reducing the order of asymptotically stable linear time-invariant systems because it preserves stability and provides computable a priori error bounds. However, the classical theory is formulated essentially for homogeneous initial conditions and therefo...

CARACTERIZACIÓN DE LA EVALUACIÓN UNIVERSITARIA EN TIEMPOS DE PANDEMIA COVID 19 – PERÚ

TORRES BENAVIDES, JUAN ANTONIO · ARELLANOS TAFUR, MIRIAM · SÁNCHEZ OLIVA, EDA · ACUÑA BELTRÁN, LUISA FERNANDA

El presente estudio aborda la caracterización de la evaluación de contenidos cognitivos, procedimentales y afectivos en la educación superior, mediante la observación de clase y entrevista estructurada, aplicados en una Universidad en Perú. La recolección de información, de corte cualitativo y cuantitativo se hizo medi...
