There is also a lack of useful statistics for Scrabble players. James Cherry, author of an on-line Scrabble computer, simulated 5000 games and presented a body of statistics on it such as means, modes and standard deviations of winning game scores, aggregate game scores, highest scoring moves, number of bingoes per game, number of moves per game, and others. Statistics invaluable to wordgame pr...

Several pathogenic strains of Escherichia coli exploit type III secretion to inject "effector proteins" into human cells, which then subvert eukaryotic cell biology to the bacterium's advantage. We have exploited bioinformatics and experimental approaches to establish that the effector repertoire in the Sakai strain of enterohemorrhagic E. coli (EHEC) O157:H7 is much larger than previously thou...

Seven cultures of Borrelia burgdorferi differing from strains B31 and ZS7 were identified from among 99 isolates from Ixodes scapularis ticks and from white-footed mice (Peromyscus leucopus) and 1 isolate from an Ixodes dentatus tick. Five of the six novel isolates from I. scapularis and the isolate from I. dentatus were from ticks feeding on humans. The six isolates from I. scapularis lacked O...

We present the techniques used in the word sense disambiguation (WSD) system that was submitted to the SENSEVAL-2 workshop. The system builds a probabilistic network per sentence to model the dependencies between the words within the sentence, and the sense tagging for the entire sentence is computed by performing a query over the network. The salient context used for disambiguation is based on...
