The social and clinical impact of the COVID-19 epidemic on the Strasbourg lung transplant cohort: A single-center retrospective cohort study.

The clinical and social impacts of the COVID-19 epidemic on lung transplant (LTx) recipients remain poorly known. We aimed to evaluate its social, clinical, and behavioral consequences on the LTx patients followed in Strasbourg university hospital. A questionnaire was used to collect details concerning patients' lifestyles, their protection methods used to avoid COVID-19 contamination, and clinical infection-related information for March 2020.

Repeated Look-up Tables.

Efficient hardware implementations routinely approximate mathematical functions with look-up tables, while keeping the error of the approximation under control. For a certain class of commonly occurring 1D functions, namely monotonically increasing or decreasing functions, we found that it is possible to approximate such functions by repeated application of a very low resolution 1D look-up table. There are many advantages to cascading multiple identical LUTs, including the promise of a very simple hardware design and the use of standard linear interpolation.

Unemployment, unemployment duration, and health: selection or causation?

This study aims at disentangling the causal effects of unemployment on physical and mental health from the selection of the unhealthy into unemployment. To identify causal effects, it explores hypotheses concerning how physical and mental health deterioration gain additional momentum with a longer duration of unemployment. In contrast, mere selection into unemployment implies time-constant effects of unemployment on physical and mental health.

Migration and the Partner Market: How Gender-Selective Relocations Affect Regional Mating Chances in Germany.

The study explores the consequences of gender-selective internal migration for regional mating chances in Germany, comparing different cohorts as well as different types of regions. Indicators of the partner market based on time series of the official German regional population statistics are combined with indicators of migration and on regional economic, educational, and settlement structures. Instead of the simple sex ratio, which is the standard measure for partner market conditions in previous research, the study at hand uses the availability ratio suggested by Goldman et al.
