Event Data Definition in LHCb

We present the approach used for defining the event object model for the LHCb experiment. This approach is based on a high level modelling language, which is independent of the programming language used in the current implementation of the event data processing software. The different possibilities of object modelling languages are evaluated, and the advantages of a dedicated model based on XML over other possible candidates are shown. After a description of the language itself, we explain the benefits obtained by applying this approach in the description of the event model of an experiment such as LHCb. Examples of these benefits are uniform and coherent mapping of the object model to the implementation language across the experiment software development teams, easy maintenance of the event model, conformance to experiment coding rules, etc. The description of the object model is parsed by means of a so called front-end which allows to feed several back-ends. We give an introduction to the model itself and to the currently implemented back-ends which produce information like programming language specific implementations of event objects or meta information about these objects. Meta information can be used for introspection of objects at run-time which is essential for functionalities like object persistency or interactive analysis. This object introspection package for C++ has been adopted by the LCG project as the starting point for the LCG object dictionary that is going to be developed in common for the LHC experiments. The current status of the event object modelling and its usage in LHCb are presented and the prospects of further developments are discussed.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 7 pages, LaTeX, 2 eps figures.

Malignant catarrhal fever in cattle in Spain

We report a case of malignant catarrhal fever in cattle in a mixed herd (ovine/bovine). The case occurred in the Basque Country (north of Spain) in April 2021. The infection was confirmed by polymerase chain reaction in a calf that had developed signs consistent with the ‘head and eye’ form of the disease. Just before its appearance, a group of five calves born at the farm (including the affected one), aged between 8 and 12 months, were temporarily housed in a pen adjacent to the sheep shed, and separated by a metallic fence that allowed direct contact. In Spain, there are no data on the incidence of malignant catarrhal fever, as there is no active surveillance programme in place. Furthermore, the disease is uncommonly considered in differential diagnosesS

Software Challenges For HL-LHC Data Analysis

The high energy physics community is discussing where investment is needed to prepare software for the HL-LHC and its unprecedented challenges. The ROOT project is one of the central software players in high energy physics since decades. From its experience and expectations, the ROOT team has distilled a comprehensive set of areas that should see research and development in the context of data analysis software, for making best use of HL-LHC's physics potential. This work shows what these areas could be, why the ROOT team believes investing in them is needed, which gains are expected, and where related work is ongoing. It can serve as an indication for future research proposals and cooperations

Rúbriques per a l'avaluació de competències

Podeu consultar la versió castellana a recurs relacionat.Aquest Quadern és una introducció a l’ús de rúbriques per a l’avaluació dels aprenentatges en l’Educació Superior. Basat en el curs «Elaboració de rúbriques per a l’avaluació de les competències transversals», organitzat per l’Institut de Ciències de l’Educació de la Universitat de Barcelona, ha recollit el resultat de la participació de professorat d’enenyaments diversos de la UB, amb la ánalitat de col·laborar interdisciplinàriament en l’elaboració de rúbriques per avaluar les competències transversals, en primer lloc, i d’elaborar rúbriques sobre les pròpies assignatures en segon lloc.Per tal d’elaborar les rúbriques sobre les competències transversals, s’han definit les competències, s’han establert indicadors i criteris d’avaluació. Considerem que el resultat de l’anàlisi, de les definicions, dels indicadors i de les mateixes rúbriques, no és generalitzable però constitueix un material de primera mà per al desenvolupament i implementació de les rúbriques en l’avaluació de les assignatures a partir dels models oferts

Rúbricas para la evaluación de competencias

Basado en el curso «Elaboración de rúbricas para la evaluación de competencias transversales», organizado por el Institut de Ciències de l’Educació de la Universitat de Barcelona, recoge el resultado de la participación del profesorado de distintas enseñanzas de la UB, con la finalidad de colaborar interdisciplinariamente en la elaboración de rúbricas para evaluar las competencias transversales, en primer lugar, y de elaborar rúbricas sobre las propias asignaturas, en segundo lugar. Para elaborar las rúbricas sobre las competencias transversales, se han definido las competencias y se han establecido indicadores y criterios de evaluación. Consideramos que el resultado del análisis, de las definiciones, de los indicadores y de las propias rúbricas no es generalizable, pero constituye un material de primera mano para el desarrollo e implementación de las rúbricas en la evaluación de las asignaturas a partir de los modelos ofrecidos.[eng] This book is an introduction to the use of rubrics for the evaluation of learnings in Higher Education. Based on the course «How to prepare rubrics for the evaluation of transversal competences», organized by the Institut of Learning Sciences of the University of Barcelona, and it’s the result of the participation of professorship from different departments of the UB, with the purpose of interdisciplinarily collaborating in the preparation of rubrics to evaluate transversal competences and to elaborate rubrics on the own subjects. To make rubrics about transversal competences, we define them and establish indicators and criteria of evaluation. We think that the result of the analysis, definitions, indicators and the own rubrics cannot be generalized, but it’s a firsthand material for the development and implementation of the rubrics in the evaluation of subjects based at offered models

A Roadmap for HEP Software and Computing R&D for the 2020s

Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.Peer reviewe
