As Director of the Office of Scientific Research and Development, Dr. Vannevar Bush has coordinated the activities of some six thousand leading American scientists in the application of science to warfare. In this significant article he holds up an incentive for scientists when the fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible o...

0031-9007= We show that matter effects change the ! oscillation probability by as much as 70% for certain ranges of energies and path lengths. Consequently, the ! survival probability also undergoes large changes. A proper understanding of survival rates must consider matter effects in P as well as P e. We comment on (a) how these matter effects may be observed and the sign of 31 determined in ...

Model a network as an edge-weighted graph, where the (unknown) weight we of edge e indicates the frequency of observed interactions, and over time t we observe a Poisson(twe) number of interactions across edges e. How should we estimate some given statistic of the underlying network? This leads to wide-ranging and challenging problems, on which this article makes only partial progress.

With visual analytical tools becoming more sophisticated and prevalent in the analysis communities, it is now apparent that understanding how analysts utilize these tools is more important than ever. Such understanding can lead to improving the tools, but a more subtle and equally important aspect lies in the discovery of the analysts’ reasoning process for solving complex problems through the ...

The title of my talk, “Living Neoplatonism,” is intentionally ambiguous, for it can refer, first, to Neoplatonism as a living philosophy rather than as a historical artifact embodied in the writings of Plotinus, Proclus, and the rest. And second, it can refer to the practice of living Neoplatonically as a modern way of life. But why Neoplatonism, as opposed to some other philosophy? From my per...
