Abstract

The notion of Virtual Power Plant (VPP) has been used many times in last years in power systems and for several reasons. As a general trend, the behavior of a classic synchronous generator is to be emulated for a class of conventional grid components like, e.g., renewable generators or/and power electronic units. Most of the times production of these units is of interest, as it is the case for the new AGC scheme of Spain which, from this point of view, looks like a VPP. However, dynamic aspects are of high importance, especially for increasing the actual rate of penetration of Renewable Energy Sources (RES). Indeed, to go above the actual rate of RES penetration, one should deal with full participation of RES to grid services. For that, we propose here a new concept called Dynamic VPP (DVPP) which fully integrates the dynamic aspects at all levels: locally (for each RES generator), globally (for grid ancillary services and interaction with other neighbor elements of the grid) and economically (for internal optimal dispatch and participation to electricity markets). A DVPP is a set of RES along with a set of control and operation procedures. This means methodologies for: choosing the participating RES, optimal and continuous operation as a whole (especially in case of loss of natural resources - e.g., wind, sun - on a part of the DVPP), regulation (in the dynamic sense) to ensure local objectives for each generator, participation to ancillary services of the DVPP as a unit and to diminish negative effects of interaction with neighbor dynamics elements of the power system, integration in both actual power systems scenarios (with mixed classic and power electronics based generation) and future ones with high degree of RES penetration.

Abstract

The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we describe the design of new readout chambers and front-end electronics, which are driven by the goals of the experiment. Gas Electron Multiplier (GEM) detectors arranged in stacks containing four GEMs each, and continuous readout electronics based on the SAMPA chip, an ALICE development, are replacing the previous elements. The construction of these new elements, together with their associated quality control procedures, is explained in detail. Finally, the readout chamber and front-end electronics cards replacement, together with the commissioning of the detector prior to installation in the experimental cavern, are presented. After a nine-year period of R&D, construction, and assembly, the upgrade of the TPC was completed in 2020., Comment: 88 pages, 60 figures

Abstract

A large Time Projection Chamber is the main device for tracking and charged-particle identification in the ALICE experiment at the CERN LHC. After the second long shutdown in 2019/20, the LHC will deliver Pb beams colliding at an interaction rate of about 50 kHz, which is about a factor of 50 above the present readout rate of the TPC. This will result in a significant improvement on the sensitivity to rare probes that are considered key observables to characterize the QCD matter created in such collisions. In order to make full use of this luminosity, the currently used gated Multi-Wire Proportional Chambers will be replaced. The upgrade relies on continuously operated readout detectors employing Gas Electron Multiplier technology to retain the performance in terms of particle identification via the measurement of the specific energy loss by ionization d$E$/d$x$. A full-size readout chamber prototype was assembled in 2014 featuring a stack of four GEM foils as an amplification stage. The performance of the prototype was evaluated in a test beam campaign at the CERN PS. The d$E$/d$x$ resolution complies with both the performance of the currently operated MWPC-based readout chambers and the challenging requirements of the ALICE TPC upgrade program. Detailed simulations of the readout system are able to reproduce the data., Comment: Submitted to NIM A

Abstract

Background: In October 2018, the University of Witten/Herdecke (UW/H) launched the new reformed medical education programme called Medicine 2018+. A major innovation compared to the existing model programme was the introduction of thematic focuses. A longitudinal communication skills curriculum was integrated into the new thematic focus "professional and personal development - inner work" (IAP). With the start of the new programme, the IAP curriculum has been built step-by-step over time, i.e. the first four semesters have already been implemented, the following semesters are being planned.Project description: IAP aims to provide students with patient-centred medicine. Five areas of competence were defined: Doctor-patient communication, team competence, staying healthy, my paths to becoming a doctor, medicine and society. The focus of this article is on the communication curriculum. The first year of study focusses on the training of basic communication skills. In the 2nd year of study, students practice these basic skills in small groups with simulated patients (SP), whereby the emphasis in the 3rd semester is on history taking and in the 4th semester is on sharing information. In the 3rd semester, students complete a communication station in an OSCE. From the 5th semester onwards, the focus of training is on the consolidation of basic and advanced communication skills, which can be applied in clinical clerkships, and the reflection of clinical experiences. Key didactic elements are, in addition to teaching the theoretical basics, experience-based small group work with and without SP, feedback and reflection. The evaluation of the summer semester 2020 showed high agreement ratings of the students regarding the overall satisfaction with the individual courses (83-100% agreement).Discussion: The introduction of IAP has been very positively received by the students. Challenges are the adequate handling of the increasing student workload when planning new courses, the, Hintergrund: Im Oktober 2018 startete die Universität Witten/Herdecke (UW/H) mit dem neuen Modellstudiengang Medizin 2018+. Eine wesentliche Neuerung im Vergleich zum bestehenden Modellstudiengang war die Einführung von Themenschwerpunkten. In den neuen Themenschwerpunkt "Berufliche Persönlichkeitsentwicklung - Innere Arbeit" (IAP) wurde das longitudinale Kommunikations-Curriculum integriert. Mit dem Start des neuen Modellstudiengangs wächst das IAP-Curriculum auf, d.h. die ersten vier Semester wurden bereits durchgeführt, die weiteren Semester sind in Planung.Projektbeschreibung: IAP hat zum Ziel, den Studierenden eine patient*innenzentrierte Medizin zu vermitteln. Fünf Kompetenzbereiche wurden definiert: Arzt*in-Patient*in Kommunikation, Teamkompetenz, Gesund bleiben!, Meine Wege hin zum Arzt/zur Ärztin sowie Medizin und Gesellschaft. Der Schwerpunkt des Artikels liegt auf der Darstellung des Kommunikations-Curriculums. Im ersten Studienjahr werden kommunikative Basiskompetenzen vermittelt. Im 2. Studienjahr üben die Studierenden diese Basiskompetenzen in kleinen Gruppen mit Simulationspatient*innen (SP), wobei im 3. Semester der Schwerpunkt auf der Anamnese und im 4. Semester auf der Weitergabe von Informationen liegt. Im 3. Semester durchlaufen die Studierenden eine Kommunikationsstation in einem OSCE. Ab dem 5. Semester liegt der Unterrichtsfokus auf der Vertiefung von Themen in Anlehnung an klinische Blöcke und der Reflexion klinischer Erfahrungen. Zentrale didaktische Elemente sind neben der Vermittlung der theoretischen Grundlagen die erfahrungsbasierte Kleingruppenarbeit mit und ohne SP, Feedback und Reflektion. Die bisherige Evaluation des Sommersemesters 2020 zeigt hohe Zustimmungswerte der Studierenden hinsichtlich der Gesamtzufriedenheit mit den einzelnen Veranstaltungen (83-100% Zustimmung).Diskussion: Die Einführung von IAP ist von den Studierenden sehr positiv aufgenommen worden. Herausforderungen stellen der angemessene Umgang mit dem zunehmenden Wo
