Abstract Objective To conduct a bibliometric analysis of the prospects and obstacles associated with dual- and multi-energy CT in thoracic disease, emphasizing its current standing, advantages, and areas requiring attention. Methods The Web of Science Core Collection was queried for relevant publications in dual- and multi-energy CT and thoracic applications without a limit on publication date or language. The Bibliometrix packages, VOSviewer, and CiteSpace were used for data analysis. Bibliometric techniques utilized were co-authorship analyses, trend topics, thematic map analyses, thematic evolution analyses, source’s production over time, corresponding author’s countries, and a treemap of authors’ keywords. Results A total of 1992 publications and 7200 authors from 313 different sources were examined in this study. The first available document was published in November 1982, and the most cited article was cited 1200 times. Siemens AG in Germany emerged as the most prominent author affiliation, with a total of 221 published articles. The most represented scientific journals were the “European Radiology” (181 articles, h-index = 46), followed by the “European Journal of Radiology” (148 articles, h-index = 34). Most of the papers were from Germany, the USA, or China. Both the keyword and topic analyses showed the history of dual- and multi-energy CT and the evolution of its application hotspots in the chest. Conclusion Our study illustrates the latest advances in dual- and multi-energy CT and its increasingly prominent applications in the chest, especially in lung parenchymal diseases and coronary artery diseases. Photon-counting CT and artificial intelligence will be the emerging hot technologies that continue to develop in the future. Critical relevance statement This study aims to provide valuable insights into energy-based imaging in chest disease, validating the clinical application of multi-energy CT together with photon-counting CT and effectively increasing utilization in clinical practice. Key Points Bibliometric analysis is fundamental to understanding the current and future state of dual- and multi-energy CT. Research trends and leading topics included coronary artery disease, pulmonary embolism, and radiation dose. All analyses indicate a growing interest in the use of energy-based imaging techniques for thoracic applications. Graphical Abstract

<h4>Background</h4>The European rivaroxaban post-authorization safety study evaluated bleeding risk among patients initiated on rivaroxaban or vitamin K antagonists for the treatment and secondary prevention of venous thromboembolism in routine clinical practice.<h4>Methods</h4>Cohorts were created using electronic healthcare databases from the UK, the Netherlands, Germany and Sweden. Patients with a first prescription of rivaroxaban or vitamin K antagonist during the period from December 2011 (in the UK, January 2012) to December 2017 (in Germany, December 2016) for venous thromboembolism indication, with no record of atrial fibrillation or recent cancer history, were observed until the occurrence of each safety outcome (hospitalization for intracranial, gastrointestinal, urogenital or other bleeding), death or study end (December 2018; in Germany, December 2017). Crude incidence rates of each outcome per 100 person-years were computed.<h4>Results</h4>Overall, 44 737 rivaroxaban and 45 842 vitamin K antagonist patients were enrolled, mean age, 59.9-63.8 years. Incidence rates were similar between rivaroxaban and vitamin K antagonist users with some exceptions, including higher incidence rates for gastrointestinal bleeding in rivaroxaban users than in vitamin K antagonist users. Among rivaroxaban users, mortality and bleeding risk generally increased with age, renal impairment and diabetes.<h4>Conclusions</h4>This study provides further data from routine clinical practice that broadly support safety profile of rivaroxaban for VTE indication and complement findings from previous randomized clinical trials.
Background: Migration-related factors, such as language barriers, can be relevant to the risk, healthcare and complications of type 2 diabetes in people with a history of migration. Diabetes-related data from people with selected citizenships were analysed on the basis of the nationwide survey German Health Update: Fokus (GEDA Fokus). Methods: The diabetes risk of persons without diabetes (n = 4,698, 18 – 79 years), key figures on healthcare and secondary diseases of persons with type 2 diabetes (n = 326, 45 – 79 years) and on concomitant diseases (n = 326 with type 2 diabetes compared to n = 2,018 without diabetes, 45 – 79 years) were stratified according to sociodemographic and migration-related characteristics. Results: Better German language proficiency is associated with a lower risk of diabetes. Diabetes-related organ complications are observed more frequently in persons who report experiences of discrimination in the health or care sector. Both persons with and without diabetes are more likely to have depressive symptoms when they reported experiences of discrimination. A stronger sense of belonging to the society in Germany is associated with reporting depressive symptoms less often in people without diabetes, but not in people with type 2 diabetes. Conclusions: The differences according to migration-related characteristics indicate a need for improvement in the prevention and care of type 2 diabetes. Migration-sensitive indicators should be integrated into the surveillance of diabetes.

IntroductionAlthough HIV has been part of our reality for over 30 years, people living with HIV (PLHIV) still experience restrictions regarding their access to healthcare. This poses a significant ethical problem, especially as it endangers achieving the goal of ending the HIV epidemic worldwide. The aim of this paper is to analyze the rulings of the European Court of Human Rights (ECtHR) regarding cases where PLHIV experienced restrictions on their access to healthcare.MethodsWe conducted an analysis of the ECtHR database and were able to identify N = 28 cases dealing with restricted access to healthcare for PLHIV. A descriptive and thematic analysis was conducted to identify ways in which access to healthcare for PLHIV was restricted.ResultsWe were able to identify a total of four main categories, with denial of adequate therapeutic support as the main category with N = 22 cases (78.57%). Most of the judgments examined were filed against Russia (N = 12, 42.86%) and Ukraine (N = 9, 32.14%). A large proportion of PLHIV in the cases studied (N = 57, 85.07%) were detainees.DiscussionThe analysis shows a clear condemnation of limited access to healthcare for PLHIV by the ECtHR. Ethical implications of the analyzed cases are discussed in detail.
As terrible as wars have always been, for the losers as well as for the winners, considering the massive killings, destruction, and general horror resulting from it all, poets throughout time have responded to this miserable situation by writing deeply moving novels, plays, poems, epic poems, and other works. The history of Germany, above all, has been filled with a long series of wars, but those have also been paralleled by major literary works describing those wars, criticizing them, and outlining the devastating consequences, here disregarding those narratives that deliberately idealized the military events. While wars take place on the ground and affect people, animals, objects, and nature at large, poets have always taken us to imaginary worlds where they could powerfully reflect on the causes and outcomes of the brutal operations. This paper takes into view some major German works from the early fifteenth through the early twentieth century in order to identify a fundamental discourse that makes war so valuable for history and culture, after all. Curiously, as we will recognize through a comparative analysis, some of the worst conditions in human history have produced some of the most aesthetically pleasing and most meaningful artistic or literary texts. So, as this paper will illustrate, the experience of war, justified or not, has been a cornerstone of medieval, early modern, and modern literature. However, it is far from me to suggest that we would need wars for great literature to emerge. On the contrary, great literature serves as the public conscience fighting against wars and the massive violence resulting from it.

This article discusses the essays by M.E. Saltykov-Shchedrin from his novels “The Golovlevs” and “Abroad” in the context of N.Ya. Danilevsky’s theory of cultural-historical types. Both of these writers can be defined as religious, though N.Ya. Danilevsky considered the possibility of proving the divine principle in nature using scientific methods. He identified specific cultural-historical types in world history as a manifestation of divine harmony, to which all world structures are subject. Definite political conclusions were drawn from this general construct: cultural-historical types of different genesis cannot interact or successfully transfer a system of values to each other. Russia’s attempt to join Europe , as viewed by N.Ya. Danilevsky, may only deprive it of political independence, “strength, integrity, and unity of the state organism.” M.E. Saltykov-Shchedrin, who had good knowledge of modern Germany and France “from the inside”, also developed a typology of the way of life and culture of Europe and Russia, but comprehended them satirically in the form of “philosophical buffoonery”. His reasoning about the absence of any native system for educating new generations in Russia and the negativism of “Europeanism” represents the viewpoint of writers of his time and subsequent eras, such as I.A. Goncharov, V.V. Rozanov, and V.G. Yanchevetsky holding a relatively marginal position. Similarly to N.Ya. Danilevsky, M.E. Saltykov-Shchedrin denied the so-called universal values by assuming that the lifestyle and political system are largely shaped by cultural particularities.

<p>The idea of estimating stratospheric aerosol optical thickness from the twilight colours in historic paintings – particularly under conditions of volcanically enhanced stratospheric aerosol loading – is very tantalizing because it would provide information on the stratospheric aerosol loading over a period of several centuries. This idea has in fact been applied in a few studies in order to provide quantitative estimates of the aerosol optical depth after some of the major volcanic eruptions that occurred during the past 500 years.
In this study we critically review this approach and come to the conclusion that the uncertainties in the estimated aerosol optical depths are so large that the values have to be considered questionable. We show that several auxiliary parameters – which are typically poorly known for historic eruptions – can have a similar effect on the red–green colour ratio as a change in optical depth typically associated with eruptions such as, for example, Tambora in 1815 or Krakatoa in 1883. Among the effects considered here, uncertainties in the aerosol particle size distribution have the largest impact on the colour ratios and hence the aerosol optical depth estimate. For solar zenith angles exceeding 80<span class="inline-formula"><sup>∘</sup></span>, uncertainties in the stratospheric ozone amount can also have a significant impact on the colour ratios. In addition, for solar zenith angles exceeding 90<span class="inline-formula"><sup>∘</sup></span> the colour ratios exhibit a dramatic dependence on solar zenith angle, rendering the estimation of aerosol optical depth highly challenging.
A quantitative determination of the aerosol optical depth may be possible for individual paintings for which all relevant parameters are sufficiently well constrained in order to reduce the related errors.</p>
Rural tourism is an important driving force for the transformation of rural society in the process of urbanization. However, besides promoting rural economy, it also interrupts the development of the rural living, human, manage and economic multi-dimensional environments. Space reconstruction in rural settlements is an important means to optimize multi-dimensional environments and revitalize rural tourism. Focusing on two types of rural settlements, namely the “relocation village” and the “sightseeing and settlement symbiosis village”, this study has revealed the affecting mechanism of space reconstruction in rural tourist locations on the local multi-dimensional environment by establishing a multi-dimensional environment evaluation system through an analytic, hierarchical process. Subsequently, based on the theoretical perspective of the reproduction of the space and the paradigm of the three-fold model, a comprehensive optimization path of rural multi-dimensional environments has been proposed. The results show that in the space reconstruction process driven by tourism: (1) the multi-dimensional environments of the “sightseeing and settlement symbiosis village” generally develop better than the “relocation village”; (2) the ecological environment is the direct benefit while the management environment and economic environment are the bottlenecks; (3) the “sightseeing and settlement symbiosis village” is more appealing to tourists who are interested in rural tourism since it keeps more rustic characteristics than the “relocation village”; (4) in order to optimize the multi-dimensional environments, “relocation village” should pay more attention to the space needs of residents, improve space utilization rates, and increase the residents’ sense of belonging; (5) “sightseeing and settlement symbiosis village” needs to resolve the contradiction between the tourism and living demands, improve the reproduction process driven by diversified entities, and reconstruct the neighborhood network under rural tourism.

Land degradation is a major environmental and social issue in temperate steppes. It is commonly determined from vegetation cover using remote sensing techniques. Steppes in eastern Mongolia are subject to resource extraction activities, such as mining and oil extraction, which affect land degradation. Recent technological progress in remote sensing has facilitated the acquirement of high-resolution data by, for example, the CubeSat satellite or unmanned aerial vehicles (UAV), providing data for detailed maps of vegetation cover and plant functional groups (PFGs). Traditional methods for monitoring vegetation cover often face typical scale issues, such as the upscaling of vegetation parameters if plot-scale field measurements are integrated to satellite data. Here, we studied the spatial distribution of PFG using machine learning and a combination of field measurements, UAV imagery (spatial resolution: 2 cm), and PlanetScope multi-temporal imagery. We provide two products at two spatial resolutions: one for UAV data, which is restricted to comparatively small areas around field measurements, and one for PlanetScope, which covers large parts of northeastern Mongolia. The results showed that the overall accuracies of UAV classification were 91–95%, whereas those of PlanetScope were 78–95%. In integrating the classified UAV data to the PlaneScope data, our proposed model minimized the scale issue that often impedes classification. Importantly, our findings revealed that the ecological effects of dirt road and railroad extended up to 60–120 m into the adjacent, otherwise less degraded steppe vegetation. A comparison between burned and unburned areas in different years indicates that wildfires affect the composition of PFG in reducing the fractional cover of graminoids and forbs, and that increasing cover of bare ground leads to a distinct and patchy mosaic of different vegetation types.
In recent years, an increasing influx of migrants to Europe has led to a heated public discourse about integration capacities within receiving countries such as Germany. During this period, German society, with its changeful immigration history, is again challenged to provide policy responses and foster migrant integration, especially in urban areas. The efforts of cities along that path, however, vary greatly. Complementing locality approaches on immigration and integration policies, which are focused on metropolises and the U.S.-American context, this article is an empirical application for understanding institutional and structural conditions for local variations in integration strategies in Germany by presenting a comparative analysis of four mid-sized cities. The particular research interest lies on discourses from interviews with local authorities and civil society actors. Our analysis reveals city-specific streamlines: For instance, discourses at a center of the ‘knowledge society’ focused on a strong municipal power structure that allowed communally-financed, sustainable projects to evolve from a historically-grounded commitment to welcome migrants and from high financial capacities at its disposal. In another case, discourses revolved around a city’s financially constraints, which were equalized by compensatory civil society networks. In other cities, progress was associated with spontaneous local happenings or individual innovative leadership. These street-level patterns create a degree of locality within the global migration discourse, since they emerge from the interplay of financial, economic, and demographic features; historical concepts; or local events. We therefore contend that urban planning initiatives would profit from considering place-specific institutions that influence integration stakeholders, which are regime-makers and foster institutional, migration-led changes.

BackgroundMethicillin-resistant Staphylococcus aureus (MRSA) is a common healthcare-associated pathogen that remains a major public health concern. Sequence type 228 (ST228) was first described in Germany and spread to become a successful MRSA clone in several European countries. In 2000, ST228 emerged in Lausanne and has subsequently caused several large outbreaks. Here, we describe the evolutionary history of this clone and identify the genetic changes underlying its expansion in Switzerland.Materials and MethodsWe aimed to understand the phylogeographic and demographic dynamics of MRSA ST228/ST111 by sequencing 530 representative isolates of this clone that were collected from 14 European countries between 1997 and 2012.ResultsThe phylogenetic analysis revealed distinct lineages of ST228 isolates associated with specific geographic origins. In contrast, isolates of ST111, which is a single locus variant of ST228 sharing the same spa type t041, formed a monophyletic cluster associated with multiple countries. The evidence points to a German origin of the sampled population, with the basal German lineage being characterized by spa type t001. The highly successful Swiss ST228 lineage diverged from this progenitor clone through the loss of the aminoglycoside-streptothricin resistance gene cluster and the gain of mupirocin resistance. This lineage was introduced first in Geneva and was subsequently introduced into Lausanne.ConclusionOur results reveal the radiation of distinct lineages of MRSA ST228 from a German progenitor, as the clone spread into different European countries. In Switzerland, ST228 was introduced first in Geneva and was subsequently introduced into Lausanne.
Depuis la Renaissance, la mise en scène de la nature par le biais de pratiques discursives et matérielles gagne en importance. Tenant compte de la dimension historique et culturelle, l’importance de la technique dans le processus de cette mise en scène de la nature se trouvera au centre de notre intérêt. La culture étant ici toujours considérée culture technique, ceci mène à la conclusion inverse que la technique fait partie de la culture qui implique la nature technicisée. En partant de deux objets d’études des XVIIe et XIXe siècles - les œuvres de Salomon de Caus sur les machines pour le jardin Hortus Palatinus et la correction du cours du Rhin – nous démontrerons à l’aide du concept de Techno-Natur d’une part l’hybridité entre nature et technique et d’autre part l’effet délimitant de la technique dans les mises en scène de la nature.
With the guiding principle “Learning from Athens” the 14th edition of documenta in 2017 was presented in the form of two nearly simultaneous, separate and at the same time related exhibitions in two historically very different and rather distant cities, Kassel and Athens, respectively in two different countries, Germany in the middle of Europe and Greece on the outskirts of Europe.
With this curatorial approach Artistic Director Adam Szymczyk obviously goes against the principles of the venerable art institution, which was founded in 1955 by artist and art educator Arnold Bode in Kassel and, since then, is implemented as a periodical exhibition with a 100-day duration at its venue in Kassel. Moreover, Szymczyk disengages documenta from its well-established position as a hosting institution that traditionally invites artists and cultural creators from all over the world to Kassel, and assigns it a new role as guest with the aim to manifest “the dissolution of barriers separating those who lack the simplest means from those who are usually all-too-willing to give them lessons but seldom a hand”, as he articulated in his concept in 2013.
In this paper, I will investigate how the curatorial concept of documenta 14 challenges not only the institutional history, structure and status of documenta but also how it resumes and transforms documenta’s initial understanding of an ethics of cultural connectivity in times of crisis and traumatic historical ruptures for today. From a transcultural perspective, I will critically examine, how far the curatorially initiated “terms of invitation” and “forms of collaboration” for the exhibition between Kassel and Athens can be acknowledged as a shared cultural practice within an open process that goes beyond the simple logic of oppositions between North and South, or the West and ‘the Rest’, binaries of exclusion and inclusion, or any essentializing and reducing criteria of national identity. According to this, I will also discuss how documenta 14’s claim “Learning from Athens” addresses and implements fundamental ideas of critical art education, which are strongly related to democratic conditions of participation and the legitimacy to produce knowledge and meaning in a globally interconnected and increasingly unpredictable world.
