Theory and experiment on the London moment is reviewed. A simple mathematical model is motivated and then used to study the responses of a spherical superconductor to an external field and to rotation. It reveals a connection between perfect diamagnetism (Meissner effect) and the London moment. In the model neither of these are exact but the deviation from B = 0 internal field in the former and...

Urban data ranging from images and laser scans to traffic flows are regularly analyzed and modeled leading to better scene understanding. Commonly used computational approaches focus on geometric descriptors, both for images and for laser scans. In contrast, in urban planning, a large body of work has qualitatively evaluated street networks to understand their effects on the functionality of ci...

background recent british national health service (nhs) reforms, in response to austerity and alleged ‘health tourism,’ could impose additional barriers to healthcare access for non-european economic area (eea) migrants. this study explores policy reform challenges and implications, using excerpts from the perspectives of non-eea migrants and health advocates in london.   methods a qualitative ...
