Liturgie und Gottesdienstübertragungen im Fernsehen. Liturgiewissenschaftliche Reflexionen

Seit das Zweite Deutsche Fernsehen im vergangeneo Jahr dazu übergegangen ist, vierzehntägig am Sonntag eine Meßfeier zu übertragen, ist erstmals seit den 5Oer Jahren wieder eine rege theologische, insbesondere liturgiewissenschaftliche Diskussion über Ziel und Ch_arakter solcher Übertragungen in Gang gekommen.' Die folgenden Überlegungen wollen Anstöße für die weitere Beschäftigung mit dem Thema geben. Der erste Teil zeigt die Schwierigkeiten auf, vor denen die Liturgiewissenschaft bei der Diskussion um Gottesdienstübertragungen steht. Ein zweiter Teil setzt sich kritisch mit den wesentlichen Bedenken der Liturgiewissenschaftler den Gottesdienstübertragungen gegenüber auseinander. Abschließend wird versucht, die Richtung zu skizzieren, in die eine weitere Arbeit an diesem Thema gehen könnte. (...)  EnglishThe author discusses the different opinions on the difficulties of broadcasting liturgies on televisionand concludes that broadcasting services on TV is quite useful in the theological sense, if it isintegrated into a broader pastoral conception. Television broadcasts of services should be supplementedby other forms of transmission that are able to show religious experience in a more media-specific way. In this respect, liturgy scientists and television practicians should cooperate closerwith one another

Active thermal conductivity of hot glass

For (semi)transparent glass, it is suggested to distinguish between an active and a passive thermal conductivity. Essentially, the latter is attached to the heat transfer through long-range photons most of which are both emitted and absorbed outside the glass volume, the former to the heat transfer through phonons and short-range photons which have an intense energy exchange with the glass. As the temperature distribution in the glass volume can be influenced only by the heat exchange in which the glass is actively involved, it is determined by the active thermal conductivity. The sum of the active and the passive thermal conductivity, which is identical to the so-called apparent thermal conductivity, indicates the overall heat flux through the glass. Like the apparent thermal conductivity, the active thermal conductivity can be obtained from the prototype of thermal conductivity measurements where the heat flux through a sample between two heat reservoirs of different temperatures is measured. The apparent thermal conductivity follows from the usual reduction o f the measurement data, the active thermal conductivity is derived via a differentation rule. Comparing the calculation and the measurement of the temperature inside a cooling block of glass, this differentiation rule is verified

Soweit das Auge reicht: Frömmigkeit und Visualität vom Frühmittelalter bis zur Reformation

Der Band präsentiert die gesammelten Aufsätze des Historikers und Theologen Thomas Lentes (1962 - 2020). Als einer der innovativsten Mediävisten und Theologen setzte er sich fächerübergreifend mit den körperlichen und bildlichen Ausdrucksformen der Frömmigkeit und Liturgie des Mittelalters und der Frühen Neuzeit auseinander. Dabei lotete er immer wieder den Anteil des materiellen und inneren Bildes in Andacht oder Messe aus und bewirkte durch seine präzisen Analysen der Schrift­ und Bildquellen eine Neubewertung der Frömmigkeit des späten Mittelalters

Three-dimensional Radiative Heat Transfer in Glass Cooling Processes

For the numerical simulation of 3D radiative heat transfer in glasses and glass melts, practically applicable mathematical methods are needed to handle such problems optimal using workstation class computers. Since the exact solution would require super-computer capabilities we concentrate on approximate solutions with a high degree of accuracy. The following approaches are studied: 3D diffusion approximations and 3D ray-tracing methods.Um den Wärmetransport durch Strahlung in 3D-Geometrie zu beschreiben, werden praktikable mathematische Verfahren benötigt, die es erlauben, solche Probleme auf Computern der Workstation-Klasse optimal zu lösen. Da die volle Lösung der Wärmetransportgleichnung (inklusiv Strahlungswärme) Super-Computer erfordern würde, werden im folgenden Näherungsverfahren vorgestellt, die eine hinreichend genaue Lösung gestatten. Dazu gehören Diffusionsapproximationen und Ray-Tracing in 3D-Geometrie

An artificial intelligence-assisted clinical framework to facilitate diagnostics and translational discovery in hematologic neoplasiaResearch in context

Summary: Background: The increasing volume and intricacy of sequencing data, along with other clinical and diagnostic data, like drug responses and measurable residual disease, creates challenges for efficient clinical comprehension and interpretation. Using paediatric B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) as a use case, we present an artificial intelligence (AI)-assisted clinical framework clinALL that integrates genomic and clinical data into a user-friendly interface to support routine diagnostics and reveal translational insights for hematologic neoplasia. Methods: We performed targeted RNA sequencing in 1365 cases with haematological neoplasms, primarily paediatric B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) from the AIEOP-BFM ALL study. We carried out fluorescence in situ hybridization (FISH), karyotyping and arrayCGH as part of the routine diagnostics. The analysis results of these assays as well as additional clinical information were integrated into an interactive web interface using Bokeh, where the main graph is based on Uniform Manifold Approximation and Projection (UMAP) analysis of the gene expression data. At the backend of the clinALL, we built both shallow machine learning models and a deep neural network using Scikit-learn and PyTorch respectively. Findings: By applying clinALL, 78% of undetermined patients under the current diagnostic protocol were stratified, and ambiguous cases were investigated. Translational insights were discovered, including IKZF1plus status dependent subpopulations of BCR::ABL1 positive patients, and a subpopulation within ETV6::RUNX1 positive patients that has a high relapse frequency. Our best machine learning models, LDA and PASNET-like neural network models, achieve F1 scores above 97% in predicting patients’ subgroups. Interpretation: An AI-assisted clinical framework that integrates both genomic and clinical data can take full advantage of the available data, improve point-of-care decision-making and reveal clinically relevant insights promptly. Such a lightweight and easily transferable framework works for both whole transcriptome data as well as the cost-effective targeted RNA-seq, enabling efficient and equitable delivery of personalized medicine in small clinics in developing countries.
