  This study applies the Physical Optimum (PhO) as a reference value to rate the efficiency of two technical options for the oxygen supply of a hospital. The systematic comparison of the alternative processes using the PhO as a benchmark for the minimum input (exergy in this case) required to run a process with a certain benefit allows to determine the potential for optimization of each technology. Differences are analyzed by visualizing the losses of each individual production step in a process as well as by the resulting overall energy demand, including the primary energy. Possible alternatives are purchasing liquid oxygen from a cryogenic process or the production by means of Pressure Swing Adsorption (PSA) on site. The cryogenic production shows a lower exergy demand even though it also has a higher potential for optimization. Yet, the total losses, significantly impacted by the unavoidable transportation, sum up, resulting in the conclusion that the PSA is the preferable option overall, considering energy aspects. Finally, additional criteria such as economic, legal, and structural consequences of the respective choices are briefly outlined.

• Two-loop prediction of the anomalous magnetic moment of the muon in the Two-Higgs Doublet Model with GM2Calc 2

  Athron, P. ., Balazs, C. ., Cherchiglia, A. ., Jacob, D. H. J., Stöckinger, D. ., Stöckinger-Kim, H. ., & Voigt, A. . (2022). Two-loop prediction of the anomalous magnetic moment of the muon in the Two-Higgs Doublet Model with GM2Calc 2.

  We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment (a_μ^BSM) in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is one of the simplest and most popular extensions of the Standard Model. It is one of the few single field extensions that can give large contributions to a_μ^BSM. It is essential to include two-loop corrections to explain the long standing discrepancy between the Standard Model prediction and the experimental measurement in the Two-Higgs Doublet Model. The new version GM2Calc 2 implements the state of the art two-loop calculation for the general, flavour violating Two-Higgs Doublet Model as well as for the flavour aligned Two-Higgs Doublet Model and the type I, II, X and Y flavour conserving variants. Input parameters can be provided in either the gauge basis or the mass basis, and we provide an easy to use SLHA-like command-line interface to specify these. Using this interface users may also select between Two-Higgs Doublet Model types and choose which contributions to apply. In addition, GM2Calc 2 also provides interfaces in C++, C, Python and Mathematica, to make it easy to interface with other codes.

• Potential of Onshore Wind Turbine Inertia in Decarbonising the Future Irish Energy System

  Thiesen, H. ., & Jauch, C. . (2022). Potential of Onshore Wind Turbine Inertia in Decarbonising the Future Irish Energy System. Applied Sciences, 12(6), 16. http://doi.org/10.3390/app12062984 (Original work published März 2021)

  Abstract

  Power system inertia is an essential part for grid frequency stability and decreases due to the replacement of fossil fuel fired power plants with variable renewable energy sources. This development is not represented sufficiently in unit commitment and economic dispatch models. If considered at all, only synchronous inertia from fossil fuel driven power plants is modelled. This results in increased CO2 emissions, curtailed renewable energy and high system costs. While wind turbines are a source for synthetic inertia and an important renewable energy source, their capability to provide inertia is not incorporated into energy system models. The work at hand closes this research gap and applies a methodology to depict synthetic inertia provided by wind turbines as part of the optimisation dispatch model. A unit commitment and economic inertia dispatch model of the the all-Island Irish power system is created. The potential of wind inertia is analysed and quantified by assessing CO2 emissions, curtailed renewable energy and system costs. Results show that synthetic inertia provided by wind turbines can save up 30.99% of the CO2 emissions, reduce curtailment by up to 39.90% and reduce system costs by 32.72%.

• FlexibleDecay: An automated calculator of scalar decay widths

  Abstract

  We present FlexibleDecay, a tool to calculate decays of scalars in a broad class of BSM models. The tool aims for high precision particularly in the case of Higgs boson decays. In the case of scalar and pseudoscalar Higgs boson decays the known higher order SM QED, QCD and EW effects are taken into account where possible. The program works in a modified MS scheme that exhibits a decoupling property with respect to heavy BSM physics, with BSM parameters themselves treated in the MS/DR-scheme allowing for an easy connection to high scale tests for, e.g., perturbativity and vacuum stability, and the many observable calculations readily available in MS/DR programs. Pure BSM effects are taken into account at the leading order, including all one-loop contributions to loop-induced processes. The program is implemented as an extension to FlexibleSUSY, which determines the mass spectrum for arbitrary BSM models, and does not require any extra configuration from the user. We compare our predictions for Higgs decays in the SM, singlet extended SM, type II THDM, CMSSM and MRSSM, as well as for squark decays in the CMSSM against a selection of publicly available tools. The numerical differences between our and other programs are explained. The release of FlexibleDecay officially deprecates the old effective couplings routines in FlexibleSUSY.

  Im Rahmen der Studie werden wirtschaftliche St arken und Schw achen beidseits der deutsch-d anischen Grenze sowie Handlungsfelder f ur eine vertiefte Kooperation in der Grenzregion identifiziert. Es wird analysiert, welche "kritischen Massen" in der Grenzregion mobilisiert werden k onnten, um auf beiden Seiten der Grenze Schw achen zu uberwinden und die Gesamtregion im Wettbewerb um Investoren und knappe Arbeitskr afte zu st arken. Auf Grundlage einer Expertenbefragung werden Schl usselfaktoren f ur die Entwicklung der Grenzregion abgeleitet und m ogliche Entwicklungsszenarien f ur die deutsch-d anische Grenzregion modelliert. Das Autorenteam zeigt dar uber hinaus, dass die Erfahrungen und Kooperationsmodelle bereits st arker integrierten Grenzregionen Lerneffekte f ur die Institutionalisierung der Zusammenarbeit und insbesondere f ur die Ausgestaltung von Arbeitsmarktkooperationen bieten. — — The study identifies economic strengths and weaknesses on both sides of the German-Danish border as well as fields of action for deeper cooperation in the border region. It analyzes which "critical masses" could be mobilized in the border region to overcome weaknesses on both sides of the border and to strengthen the overall region in the competition for investors and scarce labor. Based on an expert survey, key factors for the development of the border region are derived and possible development scenarios for the German-Danish border region are modeled. The team of authors also shows that the experiences and cooperation models of already more integrated border regions offer learning effects for the institutionalization of cooperation and especially for the design of labor market cooperation.

  Abstract

  This book is the result of research carried out in partnership with seven European universities as part of an Erasmus+ project on training teachers of Language for Specifi c Purpose (LSP) in higher education. All university partners, i.e. Bordeaux (France), Zagreb (Croatia), Jade (Germany), Cádiz (Spain), Adam Mickiewicz (Poland), Ljubljana (Slovenia), Arcola Research (UK), and Bergamo (Italy) carried out surveys and developed a detailed report showing that in Europe there is very little training for this type of teaching, and that teachers generally need to be trained in the specifi cities of the language fi eld they are going to teach. Medical or maritime English, legal Spanish, French for tourism, etc. require both an expert domain knowledge and a grounding in language teaching. Several testimonies highlight this situation and show the lack of career development prospects for LSP teachers at European universities. The members of the Erasmus+ TRAILs project have therefore been interested in the specifi c needs of LSP teachers and have been able to update the information through several types of surveys. The competences of LSP teachers were thus identifi ed. Based on this precise inventory, they are proposing to draw up a complete training programme. A pedagogical approach has been developed: resources, lesson preparation, course design, innovative pedagogical approaches are presented. The research presented in this book goes well beyond the TRAILs project and questions the training of specialised language teachers. More generally, it highlights the need to provide effective training and professional development for LSP teachers and offers a contribution to overcoming the shortcomings of LSP teacher education.
