Media sport has a long history as a significant site of media innovation, and existing work in media and cultural studies has explored how media sport, technological innovation and regulatory frameworks interact. However, this work often focuses on how major actors such as broadcasting organisations, sporting bodies and telecommunications companies mediate sport. As a complementary strategy to this ‘top-down’ analysis, we approach media sport through the lens of practice, which allows us to understand everyday forms of engagement with, and consumption of, media sport in a clearer fashion. The article analyses existing policy discourses and social commentaries centred on the targeted ‘high-quality’ or ‘high-tech technological’ innovation, and argues that users of sports media are also motivated by series of cultural rewards and varied tradeoffs that do not map neatly onto industrial categories of quality or media consumption trends.

Abstract Motivation We present the first tool for unbiased quality control of top-down proteomics datasets. Our tool can select high-quality top-down proteomics spectra, serve as a gateway for building top-down spectral libraries and, ultimately, improve identification rates. Results We demonstrate that a twofold rate increase for two E. coli top-down proteomics datasets may be achievable.

AbstractRecent advances in surface nanomachining have allowed the fabrication of mechanical structures with dimensions reaching 20 nm, and resonant frequencies in the 100s of MHz. Structural issues prevent the “top-down” surface machining of high-quality NEMS resonators. Such systems are alternatively to be bestowed by “bottom-up” manufacturing technologies. We report the surface assembly of RF-range NEMS. Using electrofluidic assembly, we have successfully positioned Rh mechanical beams onto specific sites of a silicon circuit. With diameters as small as 250 nm and lengths varying from 2 to 3 [.proportional]m, preliminary results show mechanical resonances ranging from 5 MHz to 80 MHz, and quality factors reaching 500. We also report the development of nanostructured NEMS for sensor applications, and present strategies for their deployment in integrative nanosystems.
