A pride of lions are prowling among the vertices and edges of an n×n grid. If their paths are known in advance, is it possible to design a safe path for a man that avoids all lions, assuming that man and lion move at the same speed? In their recent paper [4], Dumitrescu et al. employed probabilistic arguments to show that O( √ n) lions can always be avoided. They raised the question if it is al...

In this paper we present Afasia, an interactive multimedia performance based in Homer’s Odyssey [2]. Afasia is a one-man digital theater play in which a lone performer fitted with a sensor-suit conducts, like Homer, the whole show by himself, controlling 2D animations, DVD video and conducting the music mechanically performed by a robot quartet. After contextualizing the piece, all of its techn...

This paper presents the StarT-X PCI card, a network interface unit for the Arctic Switch Fabricc4]. StarT-X provides a user-level hardware interface for message passing on a cluster of PCI-equipped host platforms. StarT-X supports three message-passing mechanisms that are tuned for diierent granularities of communication. On a SUN E5000 with StarT-X, a processor can send and receive a 64-byte m...

1951 on health care spending and physicians’ time and energy. We believe that the current PSA-based screening paradigm does not compare favorably with competing health care priorities. Some people have argued that PSA screening should at least be available for black men, because the incidence and aggressiveness of prostate cancer are greater in black than in white Americans. This proposal, howe...

OBJECTIVES Previously, the author reported a cluster of 11 cholangiocarcinoma cases exposed to 1,2-dichloropropane (1,2-DCP) and/or dichloromethane (DCM) in an offset proof-printing company. Before that report, the association between the two chemicals and cholangiocarcinoma had not been known. The current study describes two cholangiocarcinoma patients exposed to 1,2-DCP or DCM in different of...
