Introduction. Let G be a locally compact, connected topological group (satisfying the second countability axiom). Let G* be a compact space which contains a dense subset G' homeomorphic to the space G and is such that G* — G' is totally disconnected. Then, Freudenthal has proved [l, Satz IX, p. 277]1 that the set G*-G' consists of at most two distinct points. Actually, Freudenthal's theorem eve...

This paper describes a front-end stage that has been implemented and embedded into instruments dedicated to a wide variety of electrophysiological mapping applications. Emphasis during the design phase has been put towards flexibility, simplicity, and performance in various environments.

Artificial agents trying to achieve communicative goals in situated interactions in the real-world need powerful computational systems for conceptualizing their environment. In order to provide embodied artificial systems with rich semantics reminiscent of human language complexity, agents need ways of both conceptualizing complex compositional semantic structure and actively reconstructing sem...

Contact formations have proven useful for programming robots by demonstration for operations involving contact. These techniques require real time recognition of contact formations. Single ended contact formation (SECF) classifiers using only forces/torques measured at the wrist of the robot have been shown to be quite effective for this purpose. To function properly, however, previous SECF cla...

The Journal of Economic Education (JEE) has been an Internet leader among economic journals, beginning with a Web page in 1995 that included abstracts and a search engine for articles published since 1984. Full text of articles in pdf became available in 1998. This issue of the JEE inaugurates another innovation, a new section called Online. In addition to finding descriptive notes published in...

BACKGROUND Because economic data on the prophylactic usage of antibiotic in Iran are scant, we have conducted a cross-sectional study with provider perspective to measure costs and appropriate use of antibiotics in surgical wards of 6 training hospitals affiliated to Shiraz University of Medical Sciences (SUMS), Iran. METHODS Over a six-month period 1,000 consecutive patients undergoing surgi...
