BackgroundThe COVID-19 pandemic revealed a need for better collaboration among research, care, and management in Germany as well as globally. Initially, there was a high demand for broad data collection across Germany, but as the pandemic evolved, lo

Publikováno v: The Lancet Regional Health. Europe, Vol 6, Iss , Pp 100151- (2021)

Background: The second wave of the COVID-19 pandemic led to substantial differences in incidence rates across Germany. Methods: Assumption-free k-nearest neighbour clustering from the principal component analysis of weekly incidence rates of German c

An ARFIMA-based model for daily precipitation amounts with direct access to fluctuations

Autor: Katja Polotzek, Holger Kantz

Publikováno v: Stochastic Environmental Research and Risk Assessment. 34:1487-1505

Correlations in models for daily precipitation are often generated by elaborate numerics that employ a high number of hidden parameters. We propose a parsimonious and parametric stochastic model for European mid-latitude daily precipitation amounts w

We establish a set-oriented algorithm for the numerical approximation of the rotation set of homeomorphisms of the two-torus homotopic to the identity. A theoretical background is given by the concept of {\epsilon}-rotation sets. These are obtained b
