Event reconstruction for KM3NeT/ORCA using convolutional neural networks

The KM3NeT research infrastructure is currently under construction at two locations in the Mediterranean Sea. The KM3NeT/ORCA water-Cherenkov neutrino detector off the French coast will instrument several megatons of seawater with photosensors. Its main objective is the determination of the neutrino mass ordering. This work aims at demonstrating the general applicability of deep convolutional neural networks to neutrino telescopes, using simulated datasets for the KM3NeT/ORCA detector as an example. To this end, the networks are employed to achieve reconstruction and classification tasks that constitute an alternative to the analysis pipeline presented for KM3NeT/ORCA in the KM3NeT Letter of Intent. They are used to infer event reconstruction estimates for the energy, the direction, and the interaction point of incident neutrinos. The spatial distribution of Cherenkov light generated by charged particles induced in neutrino interactions is classified as shower- or track-like, and the main background processes associated with the detection of atmospheric neutrinos are recognized. Performance comparisons to machine-learning classification and maximum-likelihood reconstruction algorithms previously developed for KM3NeT/ORCA are provided. It is shown that this application of deep convolutional neural networks to simulated datasets for a large-volume neutrino telescope yields competitive reconstruction results and performance improvements with respect to classical approaches

Blue Genes : Synopsis of the workshop organized by ICM-CSIC and BAU to increase engagement and collaboration for Our Ocean and Waters

7 pagesOn October 27th, 2022, the Institut de Ciències del Mar (ICM-CSIC), a marine research institution located in Barcelona, and the College of Arts & Design of Barcelona (BAU), a higher-education centre specialized in arts and design, co-organized the first Blue Genes meeting. This meeting took place virtually in a 3-hour workshop format and counted with more than 50 participants from different locations. Its main goal was to explore in a co-creative way how to reinforce and empower the engagement of people, particularly teenagers and young adults, with our Ocean and Waters and increase networking and collaboration. This meeting was the first workshop of a series of planned activities under the Blue Genes initiativePeer reviewe

LA OPINIÓN DEL PERSONAL DOCENTE EN EDUCACIÓN PRIMARIA SOBRE LAS ACTIVIDADES DE DESARROLLO PROFESIONAL QUE REALIZA Y LA INFLUENCIA QUE TIENEN EN SU PRÁCTICA PEDAGÓGICA

El artículo presenta los resultados de un trabajo de investigación cuyo objetivo general fue analizar las actividades de desarrollo profesional en las que participa el personal docente de educación primaria y la influencia en la práctica pedagógica. Se aplicaron dos técnicas de investigación: el cuestionario y la entrevista; el primero dirigido a docentes en ejercicio, mientras que la entrevista se realizó a los encargados de desarrollo profesional de diferentes instituciones en Costa Rica. Los datos obtenidos revelan que existe un interés por parte del personal docente sobre su formación continua, tanto para su crecimiento personal como para el mejoramiento de su desempeño profesional. Por su parte, las instituciones encargadas de promover el desarrollo profesional realizan los esfuerzos necesarios para atender la demanda de los centros educativos y del personal docente en general. Estas instituciones cuentan con algunas limitaciones en cuanto a los recursos humanos y económicos. Finalmente, se concluye que es necesario implementar un programa de desarrollo profesional proveniente de un ente regulador, que coordine las instituciones encargadas de estas actividades, con el fin de que el proceso se realice regularmente y no de forma aislada

The information reflects that there is an interest from teachers in their professional development, both for their personal development and also for their professional life. Professional Development institutions declared that they make an effort to attend schools demands and teachers in general. These institutions have limitations with their human and economic resources. Finally, the conclusion was that it is urgent to develop a professional development program that is organized by a regulation institution who coordinates all the institutions involved in this process, in order to unified efforts
