The use of the word “eternal” in the title of Richard Horton's piece “Occupied Palestine, an eternal alliance for health” (March 30, p 1084)1 is apt. It fits with his evangelical intentions “to put science in the service of social justice and selfdetermination.”2 However, Horton omits important data, leading to the spurious conclusion that President Obama, by disappointing the Palestinians, is ...

Many data management applications require integrating information from multiple sources. The sources may not be accurate and provide erroneous values. We thus have to identify the true values from conflicting observations made by the sources. The problem is further complicated when there may exist multiple truths (e.g., a book written by several authors). In this paper we propose a model called...

We argue that many future-eternal inflating spacetimes are likely to violate the weak energy condition. It is possible that such spacetimes may not enforce any of the known averaged conditions either. If this is indeed the case, it may open the door to constructing non-singular, past-eternal inflating cosmologies. Simple non-singular models are, however, unsatisfactory , and it is not clear if ...
