Testing the Verification and Validation Capability of a DCP-Based Interface for Distributed Real-Time Applications

Cyber–physical systems (CPS) integrate diverse elements developed by various vendors, often dispersed geographically, posing significant development challenges. This paper presents an improved version of our previously developed co-simulation interface based on the non-proprietary Distributed Co-Simulation Protocol (DCP) standard, now optimized for broader hardware platform compatibility. The core contributions include a demonstration of the interface’s hardware-agnostic capabilities and its straightforward adaptability across different platforms. Furthermore, we provide a comparative analysis of our interface against the original DCP. It is validated via various X-in-the-Loop simulations, reinforcing the interface’s versatility and applicability in diverse scenarios, such as distributed real-time executions, verification and validation processes, or Intellectual Property protection.This research was funded by Basque Government through the ELKARTEK programme under the AUTOTRUS project (grant number KK-2023/00019) and the European Commission’s Horizon Europe programme under the METASAT project (grant 101082622)

Use of interactive response devices for the improvement of teaching in the degrees of the Faculty of Sciences

La implantación de los nuevos Grados dentro del EEES supone un nuevo enfoque metodológico, pero sobre todo evaluador. El profesor debe esforzarse en ser capaz de valorar no sólo el nivel de conocimientos del alumnado sobre los contenidos, ya que la sociedad actual demanda un perfil de los egresados más completo basado en la formación por competencias. La adquisición de ambas facetas por parte del alumnado se basa principalmente en actividades presenciales y metodologías docentes aplicadas en el desarrollo de las asignaturas, tanto en grupo reducido como en grupo completo. Por tanto, cualquier herramienta adicional que ayude al docente a facilitar esta doble tarea es bien recibida, pues permitirá evaluar el rendimiento académico global del alumnado. Recientemente la Facultad de Ciencias ha puesto en marcha una experiencia piloto mediante la cual un nutrido grupo de profesores ha incorporado en su docencia un sistema de mandos inalámbricos de respuesta. Actualmente, la Facultad de Ciencias dispone de un total de 82 mandos inalámbricos de respuesta y tres antenas receptoras. Esta nueva tecnología ha permitido al docente realizar, de forma interactiva, preguntas colectivas al alumnado y recoger las respuestas individuales de forma inmediata. Los resultados obtenidos en este proyecto nos permiten ser muy optimistas con el uso de esta herramienta y nos animan a continuar en la misma línea. El profesorado participante se ha mostrado dispuesto a continuar empleando esta TIC en su docencia, tratando de abarcar más asignaturas, diversificar el tipo de pruebas, y emplear los mandos de respuesta en grupo completo, cuando el número de alumnos lo permita. La puesta en común de los resultados revela que, de forma general, este tipo de sistemas de respuesta incrementa el nivel de atención del alumnado, ya que se les demanda de forma continuada su participación activa durante la sesión. Se potencia la retención de conceptos, al suministrar en el acto la respuesta correcta a cada pregunta realizada. Permite también al profesorado conocer el nivel previo de conocimientos sobre la materia a impartir, ya que se puede realizar este tipo de preguntas al comienzo de la sesión y enfocar entonces su atención en las debilidades manifestadas. Asimismo se puede testar el grado de adquisición de dichos conocimientos, realizando este tipo de cuestionarios después de la sesión. Además, el tratamiento posterior de los resultados, de forma individualizada, permite gestionar de forma ágil el nivel de conocimientos y adquisición de competencias en lo que es un sistema de evaluación continua, tan necesario en los nuevos enfoques metodológicos nacidos de la implantación del EEES. Por último destacar que el profesorado participante ha considerado que se trata de una herramienta de gran utilidad para la consecución del objetivo de excelencia en la docencia, que además es eficaz y de fácil manejo, y entiende que no debe ser una actividad puntual, sino un proceso transformador en la actividad docente e interacción alumno-profesor, configurándose como una herramienta habitual en los sistemas de enseñanza-aprendizaje.Implementation of the new degrees in the EHEA involve a new methodological approach, but above all evaluation. The teacher should strive to be able to assess not only the level of knowledge of the students on the content, as the current society demands a profile of the most complete graduates based on training by competencies. The acquisition of both facets by students is based mainly on face-to-face activities and teaching methodologies applied in the development of the subjects, both in small group and in whole group. Therefore, any additional tool that helps the teacher to facilitate this double task is well received, since it will allow to evaluate the overall academic performance of the students. Recently the Faculty of Sciences has launched a pilot experience through which a large group of teachers has incorporated into their teaching a system of interactive response devices. Currently, the Faculty of Sciences has a total of 82 wireless response controllers and three receiving antennas. This new technology has enabled the teacher to interact interactively with the students and collect the individual answers immediately. The results obtained in this project allow us to be very optimistic with the use of this tool and encourage us to continue in the same line. The participating teachers have been willing to continue using this ICT in their teaching, trying to cover more subjects, diversify the type of tests, and use the full group response commands, when the number of students allows. The sharing of results reveals that, in a general way, this type of response systems increases the level of attention of the students, since they are continuously demanded their active participation during the session. The retention of concepts is strengthened by providing the correct answer to every question asked. It also allows the faculty to know the previous level of knowledge about the subject to be taught, since this type of questions can be asked at the beginning of the session and then focus their attention on the weaknesses manifested. It is also possible to test the degree of acquisition of this knowledge, performing this type of questionnaire after the session. In addition, the subsequent treatment of the results, in an individualized way, allows to manage in an agile way the level of knowledge and acquisition of competences in what is a system of continuous evaluation, so necessary in the new methodological approaches born from the implantation of the EHEA. Finally, it should be pointed out that the participating teachers have considered that this is a very useful tool for achieving the objective of excellence in teaching, which is also efficient and easy to use and understands that it should not be a specific activity, but a transforming process in the teaching activity and student-teacher interaction, being configured as a habitual tool in the teaching-learning systems

The commensal bacterium Lactiplantibacillus plantarum imprints innate memory-like responses in mononuclear phagocytes

Gut microbiota is a constant source of antigens and stimuli to which the resident immune system has developed tolerance. However, the mechanisms by which mononuclear phagocytes, specifically monocytes/macrophages, cope with these usually pro-inflammatory signals are poorly understood. Here, we show that innate immune memory promotes anti-inflammatory homeostasis, using as model strains of the commensal bacterium Lactiplantibacillus plantarum. Priming of monocytes/macrophages with bacteria, especially in its live form, enhances bacterial intracellular survival and decreases the release of pro-inflammatory signals to the environment, with lower production of TNF and higher levels of IL-10. Analysis of the transcriptomic landscape of these cells shows downregulation of pathways associated with the production of reactive oxygen species (ROS) and the release of cytokines, chemokines and antimicrobial peptides. Indeed, the induction of ROS prevents memory-induced bacterial survival. In addition, there is a dysregulation in gene expression of several metabolic pathways leading to decreased glycolytic and respiratory rates in memory cells. These data support commensal microbe-specific metabolic changes in innate immune memory cells that might contribute to homeostasis in the gut.Supported by grants from the Spanish Ministry of Science, Innovation and Universities (MCIU) co-financed with FEDER funds (RTI2018-096494-B-100 to JA; BFU2016-76872-R to EB; AGL2017-86757-R to LA; SAF2015-73549-JIN to HR; SAF2016–77433-R and PID2019-110240RB-I00 to RPR).
