Crisis Informatics is a multidisciplinary research area that examines the socio-technical relationships among people, information, and technology during mass emergency events. One area of crisis informatics examines the on-line behaviors of members of the public making use of social media during a crisis event to make sense of it, to report on it, and, in some cases, to coordinate a response to...

Aims. We describe in detail the nature of XMM-Newton EPIC background and its various complex components, summarising the new findings of the XMM-Newton EPIC background working group, and provide XMM-Newton background blank sky event files for use in the data analysis of diffuse and extended sources. Methods. Blank sky event file data sets are produced from the stacking of data, taken from 189 o...

The epic decasyllable is a traditional South Slavic folk metrical form. The poems created in this rich oral tradition are of a highly formulaic nature, and possess a discernible metrical organization. My focus will be on the so-called Serbo-Croatian poems within this tradition (cf. Maretić 1907, 1935, Jakobson 1933, 1952), which have been documented in numerous volumes of verse. Among the most ...

For aficionados of the epic, to be in London between the summer of 1964 and the winter of 1972 must have been very exhilarating. During that period the London Seminar on Epic convened 31 times to hear lectures on diverse epics from both nearby and remote cultures, delivered by specialists of these poetic narratives and their literary traditions. The 12 articles that constitute the present volum...

The only proof of this I know is kind of fiddly and not enlightening. But the point is that in most categories that appear ‘in nature,’ regular, strong, and extremal epics are about the same, and all are the correct notion of quotient, while ordinary epimorphisms may not be. For example, N→ Q is epic in Rings, but not extremal epic. In Top the epics are the surjective maps, while the regular = ...

Abstract A 58-year-old male patient with degenerated St. Jude Epic mitral bioprosthesis underwent successful valve replacement using 29 mm Medical mechanical prosthesis. Case history presented here to prevent organ injury via a transeptal approach for epic bioprosthesis.

We present a work in progress aimed at measuring the spectrum of the Cosmic X-ray Background (CXB) with the EPIC detectors onboard XMM-Newton. Our study includes a detailed characterization of the EPIC non X-ray background, which is crucial in making a robust measurement of the spectrum of CXB. We present preliminary results, based on the analysis of a set of Commissioning and Performance Verif...

We study the question when a ∗-autonomous (Mix-)category has a representation as a ∗-autonomous category of a compact one. We prove that necessary and sufficient condition is that weak distributivity maps are monic (or, equivalently epic). For a Mix-category, this condition is, in turn, equivalent to the requirement that Mix-maps be monic (or epic). We call categories satisfying this property t...
