Which five molecules would you take to a remote island? If you imagine yourself as a castaway on an island you might pick water, glucose, penicillin, and ethanol in combination with aspirin. However, as a scientist, you may ask yourself which molecules impressed you most by their chemical or biological property, their impact on science, or the ingenuity and/or serendipity behind their discovery...

Captured in our combinatorial topology language, the k-set consensus task is the triple hD n ; D n ; i. D n is P(D), for some domain D, and maps each n 2 D n to the subset of n-simplexes in D n that contain at most k diierent values from the values in n. In the full version of the paper, we use Theorem 12 and Sperner's Lemma to prove that any wait-free protocol for this problem must have at lea...

One of the mostperplexing passages in Wittgenstein's Philosophical Investigations occurs in Part Two where it is asserted: "Ifa lion could talk, we could not understand him."[ This remark has been interpreted as anything from a mere comment concerning our conception of a lion to an empirical claim regarding the communicative capacities of lions and nonhumans in general to a highly speculative a...

This paper presents a new definition of non-active current, which is valid for single-phase and polyphase systems as well as for periodic and non-periodic waveforms. The definition is applied to a shunt compensation system, and different cases of non-periodic current compensation are studied. A variety of compensation characteristics of non-periodic currents and the rating requirements for the ...

The field of Information Retrieval has a long-standing tradition of rigorous evaluation, and an expectation that proposals for new mechanisms and techniques will either be evaluated in batch-mode experiments against realistic test collections, with results reported derived from standard tools; or will be evaluated through the use of user studies. This emphasis on evidence, and the desire for ve...
