    Description / Table of Contents: Zusammenfassung Die vorliegende Arbeit über Mißbildungen des Harntraktes bei Chromosomenaberrationen beruht auf einem sorgfältigen und systematischen Studium publizierter Fälle und eigener beobachteter Patienten sowie von Autopsiebefunden. Bei fehlender Angabe über den Nierenstatus wurde versucht, durch persönliche Anfrage beim Autor der Arbeit zusätzliche Angaben zu erhalten. Viele Chromosomenaberrationen gehen mit einer deutlich erhöhten Häufigkeit schwerer Mißbildungen der Nieren und Harnwege einher. Bei der Trisomie D und E sowie beim Turner-Syndrom finden sich Mißbildungen des Urinsystems in über 60%, beim “Cat-eye”-Syndrom sogar in 100% der Fälle. Bei der Trisomie 21, bei Deletion des kurzen Armes von Chromosom 4 (4p-) sowie bei Deletion des langen Armes von Chromosom 18 (18q-) und bei Ringchromosom 18 (18r) finden sich Mißbildungen der Nieren- und Harnwege seltener, aber dennoch signifikant häufiger als bei einer Normalbevökerung. Bei Patienten mit dem “Cri-du-chat”-Syndrom (5p-), mit Deletion des langen Armes des Chromosoms 13 (13q-), bei 13 Ringchromosom (13r) sowie Deletion des kurzen Armes des Chromosoms 18 (18p-) und beim Klinefelter-Syndrom dagegen scheinen gröbere Nierenmißbildungen nur gelegentlich vorzukommen. Es besteht keine direkte Korrelation zwischen Mißbildungen der Nieren oder Harnwege und Mißbildungen anderer Organe oder dysplastischen Zeichen. Zudem kann den einzelnen Trisomien und Chromosomenaberrationen keine spezifische Mißbildung des Harntraktes zugeordnet werden. Es ist deshalb unmöglich, irgendwelche Nierenanomalie mit einem speziellen Chromosom oder einer bestimmten Chromosomenregion zu korrelieren.
    Notes: Summary A review of urinary tract malformations in chromosomal aberrations is presented. This study is based on a careful evaluation of published cases as well as of our own patients and autopsy material. In trisomy D and E and in Turner's syndrome the incidence of gross urinary system malformations is more than 60%, in the cat-eye syndrome up to 100%. In trisomy 21, 4p-, 18q- und 18r syndrome malformations of the renal system are less frequent. However, in patients with the cri-du-chat syndrome (5p-) and in 13q-, 13r, 18p- and Klnefelter's syndrome, gross malformations of the urinary tract seem to occur only occasionally. There is no direct correlation of urinary tract malformation with concomitant malformations of other organs. Moreover, no specific renal malformations can be correlated to any particular chromosomal anomaly.

    Description: Substantial renewable energy (RE) cost reductions have raised the prospect of a subsidy-free RE era of the energy transition. The envisaged policy cornerstones of this era are carbon markets, which create economic incentives for sustaining further RE deployment. However, this overlooks that exposing RE to market risks and increasing interest rates would result in substantially higher financing cost, which in turn would lead to much steeper carbon price paths. The resulting political pressure may provoke a price-depressing regulatory intervention, disrupting further RE expansion. Here we conceptualize this feedback and infer indicators for the risk of such an intervention. By quantifying these indicators for the European Union, we find that increased financing cost could double carbon prices in the long term, halve the rate of renewable capacity deployment in the next 15 years and considerably increase the profits of fossil fuel plants. This implies a substantial risk of pushback that policymakers should safeguard against.

    Description: International climate finance is key to achieving the goals of the Paris Agreement. Here we develop a machine learning classifier to identify international climate finance from 2.7 million official development assistance projects between 2000 and 2019, resulting in a consistent and replicable inventory of 82,023 bilateral climate finance projects (US$80 billion). Our findings reinforce concerns that the actual numbers may be much lower than current estimates made with Rio markers.

    Description: Energy system models suggest optimal investment pathways and guide policymakers in implementing the low-carbon energy transition. Although model accuracy greatly improved over the last decade, it is unclear whether the cost of capital (CoC) is well represented, despite the parameter’s strong influence on model outcomes. In this perspective, we review 58 model-based publications that explicitly refer to CoC and observe that simply stating unfounded assumptions remains the most important “method” for determining the CoC. Overall, there appears to be a clear lack of guiding principles for how to appropriately determine CoC for use within models. To close this gap, we identify four barriers to a more accurate CoC reflection and suggest practical steps for overcoming them, including heuristic guidelines to support modelers in determining when differentiated CoC rates ought to be applied. Overall, we believe more rigorous treatment of the CoC will improve the quality of model-based policy advice.

    Description: The construction of new coal-fired power plants is frequently financed by banks from abroad. Recent studies suggest that the opportunity to export technology is a relevant 'push factor' for such financing activities. In this paper, we provide first quantitative evidence for this hypothesis on a global scale. We construct a novel dataset that tracks both public and private financial involvement on a coal unit level, including information on equipment manufacturers and service providers. The findings indicate that financial institutions from various countries, including China, Japan, South Korea, and Western nations provide loans to coal units overseas. These finance flows, particularly from publicly owned banks, are accompanied by technology exports from the same country. Complementing our quantitative analysis with semi-structured interviews, we find indications that political economy factors, such as public banks' requirement for participation of domestic firms in financing deals and the unlocking of export business opportunities for domestic industries in financing countries, contribute to this correlation. Our findings highlight the importance of financing countries and their domestic industries for low-carbon transitions globally.
