Like a newly popular nightspot, the biology of adult stem cells has emerged from obscurity to become one of the most lively new disciplines of the decade. The neurosciences have not escaped this trendy pastime and, from amid the noise and excitement, the astrocyte emerges as a beguiling companion to the adult neural stem cell. A once receding partner to neurons and oligodendrocytes, the astrocy...

The investigation of Irish demographic trends in the half century following the Famine has generally been conducted using figures relating to large areas. In this paper an attempt is made to examine the applicability of some of the hypotheses that have been developed in this context to the demographic changes that occurred in one particular community and which have been investigated in the cour...

In this paper, we consider a sink location in a dynamic network which consists of a graph with capacities and transit times on its arcs. Given a dynamic network with initial supplies at vertices, the problem is to find a vertex v as a sink in the network such that we can send all the initial supplies to v as quickly as possible. We present an O(n log n) time algorithm for the sink location prob...

Mycobacterium marinum is a photochromogenic myco bacterium capable of indu c in g a se lflimitin g loca li zed infection within the mouse foot pad ( 1.4 ). Because this infection is íwalogous to the M. leprae infection in the mouse, it has been suggested as an a lternative experimenta l model for studying the role of host immunity to M. leprae infection in the mouse foot pad (1 2. 16. 19). Pres...

A web-based nuclear reactor simulator has been developed using the best-estimate nuclear system analysis code RELAP5 as its engine, and abVIEW for graphical user interface and web-casting. Simulator retains the accuracy of the best-estimate code. Results are displayed in user riendly graphical format. Color-coded nominal values are displayed along with the current status of different variables ...

For any visually-based interaction between persons and acting systems within a real-world environment the localization of a user by the system is a necessary condition. The presented work deals with this visual loca-lization problem of a user concretely referred to the autonomous mobile robot system MILVA of our department. Since this system is applied under real-world conditions especially for...
