Adaptation to stressful environments : invasion success of the Colorado potato beetle (Leptinotarsa decemlineata)
2018
Biological invasions, specifically human-induced dispersals, are one of the major threats to our biodiversity and are predicted to increase. Invasive pests provide an opportunity to study whether adaptation to human-induced environments could promote invasions to other human-induced environments. One major anthropogenic selection pressure is created by pesticides, and pests can be exposed to various pesticides in their native, as well as introduced, ranges. I investigated whether exposure to anthropogenic selection (i.e. insecticides and herbicides) and exposure to multiple anthropogenic stressors selects for higher stress tolerance. I also tested whether parental prolonged diapause or inse…
Maradona and China: Perceptions and representations of a sports myth
2022
This article highlights specific aspects of the relationship between Maradona and the People���s Republic of China (PRC) to trace the development of the ���one-athlete brand��� in global sport and the construction of the ���foreign��� sports myth in China. These aspects include the aligned development of football in China and Maradona as an icon, manifested in the gap in the domestic space for Western athletic icons in China and Maradona���s rise during the 1986 World Cup; the political identity and interpretation of Maradona as a supporter of communist and socialist regimes amidst China���s opening and international integration; and the modern development of the Chinese sports machine and …

Online ^{222}Rn removal by cryogenic distillation in the XENON100 experiment
2017
International audience; We describe the purification of xenon from traces of the radioactive noble gas radon using a cryogenic distillation column. The distillation column was integrated into the gas purification loop of the XENON100 detector for online radon removal. This enabled us to significantly reduce the constant$^{222}$ Rn background originating from radon emanation. After inserting an auxiliary$^{222}$ Rn emanation source in the gas loop, we determined a radon reduction factor of $R\,>\,27$ (95% C.L.) for the distillation column by monitoring the$^{222}$ Rn activity concentration inside the XENON100 detector.
