Here we analyzed the symptoms experienced outside of a hospital setting. Methods: The Vienna Social Fund (FSW; Vienna, Austria), the Public Health Services of the City of Vienna (MA15) and the private company Symptoma collaborated to implement Vienna's official online COVID-19 symptom checker. Users answered 12 yes/no questions about symptoms to assess their risk for COVID-19. They could also specify their age and sex, and whether they had contact with someone who tested positive for COVID-19. Depending on the assessed risk of COVID-19 positivity, a SARS-CoV‑2 nucleic acid amplification test (NAAT) was performed. In this publication, we analyzed which factors (symptoms, sex or age) are associated with COVID-19 positivity. We also trained a classifier to correctly predict COVID-19 positivity from the collected data. Results: Between 2 November 2020 and 18 November 2021, 9133 people experiencing COVID-19-like symptoms were assessed as high risk by the chatbot and were subsequently tested by a NAAT. Symptoms significantly associated with a positive COVID-19 test were malaise, fatigue, headache, cough, fever, dysgeusia and hyposmia. Our classifier could successfully predict COVID-19 positivity with an area under the curve (AUC) of 0.74. Conclusion: This study provides reliable COVID-19 symptom statistics based on the general population verified by NAATs.

On the combinatorial side, we define multilabelled generalisations of the tree families d-ary increasing trees and generalised plane-oriented recursive trees. Additionally, we introduce a clustering process for ordinary increasing trees and relate it to bucket increasing trees. We discuss in detail the bucket size two and present a bijection between such bucket increasing tree families and certain families of graphs called increasing diamonds, providing an explanation for phenomena observed by Bodini et al. (2016, Lect. Notes Comput. Sci.9644 207-219.). Concerning structural properties of bucket increasing trees, we analyse the tree parameter Kn . It counts the initial bucket size of the node containing label n in a tree of size n and is closely related to the distribution of node types. Additionally, we analyse the parameters descendants of label j and degree of the bucket containing label j, providing distributional decompositions, complementing and extending earlier results (Kuba and Panholzer (2010), Theoret.

This is because the aforementioned variation leads to previously unrecognized correction terms, including a bulk-to-boundary inflow term that does not appear in the original calculation of the time derivative of the Brown-York energy and leads to corrective extensions of Einstein's quadrupole formula in the large sphere limit.}, subject = {gravitation}, language = {en} } @inproceedings{LeonhartsbergerPremmSchidleretal., author = {Leonhartsberger, Kurt and Premm, C. and Schidler, Susanne and Werner, Andrea and Moisl, F.}, title = {Analyse der Wirtschaftlichkeit eines dezentral organisierten PV-Heimspeichernetzwerks f{\"u}r netz- und systemdienliche Anwendungen}, series = {Tagungsband PV-Symposium 2018}, booktitle = {Tagungsband PV-Symposium 2018}, subject = {Photovoltaics}, language = {de} } @misc{GollnerPucherSchmoellebecketal., author = {Gollner, Helmut and Pucher, Robert and Schm{\"o}llebeck, Fritz and Kollmitzer, Christian}, title = {From Teaching to Learning - An Innovative Approach to Engineering Education}, subject = {Teaching}, language = {en} } @misc{KornfeindBlahaPeuschletal., author = {Kornfeind, P. and Blaha, A. and Peuschl, M. and Reichel, Martin and Sabo, Anton}, title = {2-Komponentenplattform zur Erfassung der Stemmbrettkr{\"a}fte am Ruderergometer und im Ruderboot}, subject = {Sport}, language = {de} } @article{MairhoferPasson, author = {Mairhofer, Lukas and Passon, Oliver}, title = {Reconsidering the Relation Between "Matter Wave Interference" and "Wave-Particle Duality"}, series = {Foundations of Physics}, journal = {Foundations of Physics}, number = {52/32}, publisher = {Springer}, abstract = {Interference of more and more massive objects provides a spectacular confirmation of quantum theory.

We first give an outline of the historical development of these notions. Already here it becomes evident that they are hard to define rigorously, i.e. have mainly a heuristic function. Then we discuss recent interference experiments of large and complex molecules which seem to support this heuristic function of "duality". However, we show that in these experiments the diffraction of a delocalized center-of-mass wave function depends on the interaction of the localized structure of the molecule with the diffraction element. Thus, the molecules display "dual features" at the same time, which contradicts the usual understanding of wave-particle duality.
