    Am 15.Oktober 1542 wurde erstmals in der Neupfarrkirche das Abendmahl mit Brot und Wein gefeiert und damit die Reformation in der Reichsstadt Regensburg eingeführt. Daneben blieben aber innerhalb der Stadtmauer mehrere katholische Reichsstände bestehen. So wurde Regensburg zum idealen Ort für den Immerwährenden Reichstag und Zufluchtsort für evangelische Glaubensflüchtlinge. Heute steht das konfessionelle Miteinander im Mittelpunkt. Das vorliegende Heft geht zurück auf eine Vortragsreihe der Neupfarr-Kirchengemeinde zum Reformationsjubiläum. Die Autorin ist die Leiterin des Evang.-Luth. Kirchenarchivs Regensburg

    On the generalization of agricultural drought classification from climate data

    Climate change is expected to increase the likelihood of drought events, with severe implications for food security. Unlike other natural disasters, droughts have a slow onset and depend on various external factors, making drought detection in climate data difficult. In contrast to existing works that rely on simple relative drought indices as ground-truth data, we build upon soil moisture index (SMI) obtained from a hydrological model. This index is directly related to insufficiently available water to vegetation. Given ERA5-Land climate input data of six months with land use information from MODIS satellite observation, we compare different models with and without sequential inductive bias in classifying droughts based on SMI. We use PR-AUC as the evaluation measure to account for the class imbalance and obtain promising results despite a challenging time-based split. We further show in an ablation study that the models retain their predictive capabilities given input data of coarser resolutions, as frequently encountered in climate models

    In situ synthesis of lanthanide complexes supported by a ferrocene diamide ligand: extension to redox-active lanthanide ions

    Reliable transformation of low-cost rare-earth metal oxides to organometallic rare-earth metal complexes is a prerequisite for the advancement of non-aqueous rare-earth metal chemistry. We have recently developed an in situ method to prepare rare-earth alkyl and halide precursors supported by a diamidoferrocene NNTBS, 1,1′-fc(NSiMe2tBu)2, as an ancillary ligand. Herein, we extended the scope of this method to other lanthanide ions including those that are redox active, such as cerium, praseodymium, samarium, terbium, thulium, and ytterbium. Specifically, samarium trisbenzyl could be generated in situ and then converted to the corresponding samarium benzyl or iodide complexes in good yield. However, it was found that ytterbium trisbenzyl could not be formed cleanly and the consequent conversion to ytterbium iodide complex was low yielding. By adapting an alternative route, the desired ytterbium chloride precursor could be obtained in good yield and purity
