Inferring change points in the spread of COVID-19 reveals the effectiveness of interventions
TLDR
Keeping the lid on infection spread From February to April 2020, many countries introduced variations on social distancing measures to slow the ravages of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Expand

Statistical symmetries of the Lundgren-Monin-Novikov hierarchy.
It was shown by Oberlack and Rosteck [Discr. Cont. Dyn. Sys. S, 3, 451 2010] that the infinite set of multipoint correlation (MPC) equations of turbulence admits a considerable extended set of LieExpand

Inferring COVID-19 spreading rates and potential change points for case number forecasts
TLDR
Combining an established epidemiological model with Bayesian inference, we analyze the time dependence of the effective growth rate of new infections. Expand

Pressure Hessian and viscous contributions to velocity gradient statistics based on Gaussian random fields
Abstract Understanding the non-local pressure contributions and viscous effects on the small-scale statistics remains one of the central challenges in the study of homogeneous isotropic turbulence.Expand

Large-eddy simulation study of the logarithmic law for second- and higher-order moments in turbulent wall-bounded flow
Abstract The logarithmic law for the mean velocity in turbulent boundary layers has long provided a valuable and robust reference for comparison with theories, models and large-eddy simulations (LES)Expand

The Lundgren–Monin–Novikov hierarchy: Kinetic equations for turbulence
Abstract We present an overview of recent works on the statistical description of turbulent flows in terms of probability density functions (PDFs) in the framework of the Lundgren–Monin–Novikov (LMN)Expand

Inferring change points in the COVID-19 spreading reveals the effectiveness of interventions
TLDR
We detect change points in the effective growth rate of new infections that correlate well with the times of publicly announced interventions and incorporate the corresponding change points into forecasts of future scenarios and case numbers. Expand

On the velocity distribution in homogeneous isotropic turbulence: correlations and deviations from Gaussianity
We investigate the single-point probability density function of the velocity in three-dimensional stationary and decaying homogeneous isotropic turbulence. To this end, we apply the statisticalExpand

The challenges of containing SARS-CoV-2 via test-trace-and-isolate
Without a cure, vaccine, or proven long-term immunity against SARS-CoV-2, test-trace-and-isolate (TTI) strategies present a promising tool to contain its spread. For any TTI strategy, however,Expand

Spatio-temporal spectra in the logarithmic layer of wall turbulence: large-eddy simulations and simple models
Motivated by the need to characterize the spatio-temporal structure of turbulence in wall-bounded flows, we study wavenumber–frequency spectra of the streamwise velocity component based on large-eddyExpand
