Endovascular exclusion of a saccular aortic aneurysm using a septal occluder device

Endovascular repair of aneurysms involving the visceral segment of the abdominal aorta still remains a challenge. We report a patient with a large saccular aneurysm involving the visceral segment of the abdominal aorta that was ultimately excluded by endovascular deployment of an Amplatzer atrial septal occluder device (AGA Medical/St. Jude Medical, St Paul, Minn)

New Technology Focus: Smart Polymer in Vascular Surgery

A new smart polymer technology developed by Shape Memory Medical is available to endovascular specialists. The shape memory polymer is incorporated into vascular plugs and coils. Dr Ross Milner, a vascular surgeon at University of Chicago Medicine, gives his perspective on the properties of the shape memory polymer and how smart polymer devices may be used in vascular surgery

The condition of the working class: Representation and praxis

Copyright © 2013 Immanuel Ness and Wiley Periodicals, Inc. This is the accepted version of the following article: Wayne, M. and O'Neill, D. (2013), The Condition of the Working Class: Representation and Praxis. WorkingUSA, 16: 487–503, which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1111/wusa.12076/abstract.This essay reflects critically on the political context, production process, ideas, and strategies of our feature-length documentary film The Condition of the Working Class. It explores why we were inspired by Friedrich Engels' 1844 book of the same name and how that book connects with the contemporary neoliberal capitalist project that has dominated the political scene internationally for several decades. We conceptualize our film as a constellation, in the manner of Walter Benjamin, between the 1840s and the contemporary moment. The essay explores the production process of the film, which involved setting up and working in conjunction with a theatrical project. The essay reflects on the theatrical work of John McGrath and its connections with our own work. In the final section of the essay, the authors consider the finished film in more detail, analyzing how the film focused on the process of theatrical production and contextualized that process within wider spatial and temporal frames. The film and the theater project explore the possibility of reconstituting in a microcosm a working class collective subject that has been atomized and demonized by 30 years of neoliberal policy, which in the context of the present economic crisis seeks to drive its project even further

Observation of mHz-level cooperative Lamb shifts in an optical atomic clock

We report on the direct observation of resonant electric dipole-dipole interactions in a cubic array of atoms in the many-excitation limit. The interactions, mediated by single-atom couplings to the shared electromagnetic vacuum, are shown to produce spatially-dependent cooperative Lamb shifts when spectroscopically interrogating the mHz-wide optical clock transition in strontium-87. We show that the ensemble-averaged shifts can be suppressed below the level of evaluated systematic uncertainties for state-of-the-art optical atomic clocks. Additionally, we demonstrate that excitation of the atomic dipoles near a Bragg angle can enhance these effects by nearly an order of magnitude compared to non-resonant geometries. Given the remarkable precision of frequency measurements and the high accuracy of the modeled response, our work demonstrates that such a clock is a novel platform for studies of the quantum many-body physics of spins with long-range interactions mediated by propagating photons
