Wolfgang Kern (KFU, advisor M. Holler/K. Bredies): Accelerometry-based classification of circulatory states during out-of-hospital cardiac arrest | |
Abstract: During out-of-hospital cardiac arrest treatment, reliable spontaneous circulation detection is still challenging. Thus, we train a kernelized Support Vector Machine classifier to reliably assess circulatory state during cardiac arrest employing newly developed features based on accelerometry and electrocardiogram data from real-world defibrillator records. The algorithm exhibits excellent performance on a test set. The proposed algorithm may support clinicians to assess circulatory state during cardiac arrest treatment and moreover, simplify retrospective annotation for quality management. | |

Manuel Hauke (TU, advisor C. Aistleitner): On the metric theory of approximations by reduced fractions: Quantifying the Duffin-Schaeffer conjecture | |
Abstract: Let ψ: {1,2,...}→[0,1/2] be given. Koukoulopoulos and Maynard (2020) proved the Duffin--Schaeffer conjecture: for almost all reals α there are infinitely many coprime solutions (p,q) to the inequality |α - p/q| < ψ(q)/q, if and only if the series Σ φ(q) ψ(q) / q is divergent. In a recent joint work with Christoph Aistleitner and Bence Borda, we established a quantitative version of this result in the following sense: for almost all α, the number of coprime solutions (p,q), subject to q <e Q, is of asymptotic order Ψ(Q) = Σ_{q=1,...,Q} 2φ(q) ψ(q) / q. In this talk, I will sketch the main steps of the original proof of Koukoulopoulos and Maynard as well as the additional ideas we used to obtain this quantification. | |
