If our Universe is a three-brane embedded in a five-dimensional antideSitter spacetime, in which matter is confined to the brane and gravity inhabits an infinite bulk space, then the causal propagation of luminous and gravitational signals is in general different. A gravitational signal traveling between two points on the brane can take a “shortcut” through the bulk, and appear quicker than a p...

In the research area of spatial databases, query processing based on uncertain location information has become an important research topic. In this paper, we propose an index structure for the case that the locations of a query object and target objects are imprecise and specified by Gaussian distributions with different parameters. The index structure efficiently supports probabilistic spatial...

In 1981 the Japanese announced a program of research on a fifth generation of computing systems (FGCS) that will integrate advances in very large scale integration, data base systems, artificial intelligence, and the human computer interface into a new range of computers that are closer to people in their communication and knowledge processing capabilities. The proposal was a shock at first but...

Transliteration is defined as phonetic translation of names across languages. Transliteration of Named Entities (NEs) is necessary in many applications, such as machine translation, corpus alignment, cross-language IR, information extraction and automatic lexicon acquisition. All such systems call for high-performance transliteration, which is the focus of shared task in the NEWS 2015 workshop....

This is the fifth edition of this pediatrics text, whose first edition appeared in 1964. Dr. Jolly, of the Charing Cross Hospital in London, has been joined by a new co-author, Dr. Malcolm Levene, of the University of Leicester Medical School, for this edition. Their work, Diseases of Children, is clearly a British-authored text. References to public health issues, health statistics, immunizati...

The analysis of types of uncertainty and how they affect decision making in complex settings can be considerably simplified by addressing three core questions: how uncertain we are, how aware we are of uncertainty and how context and perception affect uncertainty. The continuum nature of the answers to these questions leads naturally to represent uncertainty in a 3D level-awareness-perception p...

Some findings are reported from the three-year Researchers of Tomorrow study of research behaviour among doctoral students in ‘Generation Y’. Commissioned by the British Library and UK Joint Information Systems Committee, it is the most intensive study of its kind to date. Generation Y doctoral students are sophisticated information-seekers and users of complex information sources, highly compe...

A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance scales of the gravitational constant G, the fifth force skew symmetric field coupling strength ω and the mass of the skew symmetric field μ = 1/λ. A fit to the available anomalous acceleration data ...
