Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Rural Health at a Crossroads: How Policymakers Have Failed Rural America and What Can Be Done for a Healthier Tomorrow

The Milbank Quarterly, EarlyView.
Policy Points Rural communities have more limited access to medical care and worse health outcomes. Existing federal and state policies largely fall short in addressing rural access disparities. Rural health woes require increased government funding for providers and the embrace of alternative health delivery mechanisms, as well as expanded public ...

Pseudo-static Analysis on the Pullout Capacity of an Inclined Shallow Strip Anchor Plate Embedded in Slope Strata Under Seismic Action

工程科学与技术
ObjectiveThe uplift capacity and safety stability of anchor plates are significantly influenced by factors such as terrain relief, installation methods, and seismic loads during the service phase. This study seeks to derive analytical expressions for the

Syphilis and ‘Sons of Empire’: The ‘Prostitute’ and Britain's Fighting Arm in Nineteenth ̵ Century Colonial Punjab

Gender &History, EarlyView.
ABSTRACT The British army in India took great care to provide European troops with facilities for sexual relations while anxiously managing venereal disease. Examining archival evidence, political debates and medical discourse from the nineteenth century, this article examines the colonial military enterprise of regulated prostitution in colonial ...

Engineering Apprenticeships: Youth Transitions, Industrial Capital and the Role of Working‐Class Households

The British Journal of Sociology, EarlyView.
ABSTRACT Using biographical methods, the study explores the lives of 34 young people undertaking engineering apprenticeships in Teesside, Northeast England. It examines why working‐class youth in a deindustrialised region might be attracted to engineering, how they might secure apprenticeship, and the invaluable role households play in orchestrating ...
