Cambridge Research Lab, which he founded in 1997. Prior to joining Microsoft, he was associated with Cambridge University for nearly half a century—as an undergraduate and graduate student, as a researcher, and eventually as a professor and head of the Computer Laboratory. In this EIC message, I focus on the significance of Needham's research contributions to pervasive computing. These contribu...

Alan's work was necessarily interdisciplinary because he saw no way of understanding anatomy, physiology or behaviour without understanding all of them. Hence his work on visual plasticity and development incorporated retinal and collicular anatomy, lesion studies and neuropsychological work with patients. This led him to take up the discovery of blindsight by Larry Weiskrantz, his graduate sup...

With your permission, I shall now address you on the subject of the present situation in research in the foundations of mathematics. Since there remain open questions in this field, I am not in a position to paint a definitive picture of it for you. But it must be pointed out that the situation is not so critical as one could think from listening to those who speak of a foundational crisis. Fro...

The Taiwanese species of the genus Paridea Baly, 1886, are revised. Two new species, Paridea (Semacia) houjayi sp. n. and P. (S.) kaoi sp. n. are described. Both were confused previously with P. (S.) sexmaculata (Laboissière, 1930) and P. (S.) angulicollis (Motschulsky, 1854) respectively. Paridea (P.) sauteri (Chûjô, 1935) and P. (P.) taiwana (Chûjô, 1935) are removed from synonymy with P. (P....

AI. Although she died on 4 April 2007, she worked up until a week before her death, and her major and most lasting contributions will almost certainly be her original PhD thesis and the inverse document frequency (idf) measure of the relevance of terms. 1 The latter is the notion that a document is relevant not only because key terms are frequent in it but because those terms are infrequent in ...
