Abstract

In this thesis, a modification of an experimental setup, able to analyse atom dynamics during interaction with a high intensity field, and the first steps towards implementation are presented. The idea of the experiment is to utilize high intensity infrared (IR) radiation to perturb the atom's potential, while exciting or ionizing them with extreme ultra violet photons. The planned modifications are: 1) an external coupling of one part of the IR pulse into the existing experiment, which consists of a time delay stage and an off-axis parabolic Mirror and 2) using a high intensity IR Titanium Sapphire laser pulse centered about 800 nm, which will replace optical parametric amplified pulses centered around 1 to 2 μm. This leads to a more intense IR with a possible peak intensity in the regime of 1017 Wcm-2. These technical modifications allow for a stronger perturbation of the benchmark atom Helium, for the purpose of investigating correlated two electron wavepackets in double ionization or excitation processes.

Abstract

Background: The therapeutic success in patients with congenital heart disease (CHD) leads to a growing number of adults with CHD (adult CHD [ACHD]) who develop end-stage heart failure. We aimed to determine patient characteristics and outcomes of ACHD listed for heart transplantation., Methods: Using data from all the patients with ACHD in 20 transplant centers in the Eurotransplant region from 1999 to 2015, we analyzed patient characteristics, waiting list, and post-transplantation outcomes., Results: A total of 204 patients with ACHD were listed during the study period. The median age was 38 years, and 62.3% of the patients were listed in high urgency (HU), and 37.7% of the patients were in transplantable (T)-listing status. A total of 23.5% of the patients died or were delisted owing to clinical worsening, and 75% of the patients underwent transplantation. Median waiting time for patients with HU-listing status was 4.18 months and with T-listing status 9.07 months. There was no difference in crude mortality or delisting between patients who were HU status listed and T status listed (p = 0.65). In multivariable regression analysis, markers for respiratory failure (mechanical ventilation, hazard ratio [HR]: 1.41, 95% CI: 1.11-1.81, p = 0.006) and arrhythmias (anti-arrhythmic medication, HR: 1.42, 95% CI: 1.01-2.01, p = 0.044) were associated with a higher risk of death or delisting. In the overall cohort, post-transplantation mortality was 26.8% after 1 year and 33.4% after 5 years., Conclusions: Listed patients are at high risk of death without differences in the urgency of listing. Respiratory failure requiring invasive ventilation and possibly arrhythmias requiring anti-arrhythmic medication indicate worse outcomes on waiting list., (Copyright © 2020 International Society for Heart and Lung Transplantation.
