A Proposed Möbius Accelerator

A Proposed Fast Luminosity Feedback for the Super-b Accelerator

We present a possible design for a fast luminosity feedback for the SuperB Interaction Point (IP). The design is an extension of the fast luminosity feedback installed on the PEP-II accelerator. During the last two runs of PEP-II and BaBar (2007-2008), we had an improved luminosity feedback system that was able to maintain peak luminosity with faster correction speed than the previous system. T...

Proposed few-optical cycle laser-driven particle accelerator structure

We describe a transparent dielectric grating accelerator structure that is designed for ultrashort laser pulse operation. The structure is based on the principle of periodic field reversal to achieve phase synchronicity for relativistic particles; however, to preserve ultrashort pulse operation it does not resonate the laser field in the vacuum channel. The geometry of the structure appears wel...

A Möbius strip. Fin-de-siècle neuropsychiatry and Paul Möbius

The way ahead is shown by the last essay in the book, Karl Figlio's meaty piece of social history, 'How does illness mediate social relations? Workmen's compensation and medico-legal practice, 1890-1940'. The title is spot-on, and highlights the paper's concerns and approaches. Taking the eye malfunction, nystagmus, Figlio shows that late nineteenth-century medical interest in its exact specifi...

A weighted Möbius function

Möbius syndrome.

We describe a case of Möbius syndrome in a 3-month-old infant. Striking imaging findings of pontine hypoplasia in the region of the 6th and the 7th nerve complexes were noted. In addition, absence of the middle cerebellar peduncles was noted, a finding that, to our knowledge, has never been reported before in the literature. Clinical presentations, other radiologic findings, and a possible path...
