PLUG – Play Ubiquitous Games -, is a research project that deployed a fully distributed RFID architecture in the Museum of Arts and Crafts in Paris. A pervasive game was designed: "Plug: the Secrets of the Museum" (PSM) where players had to find virtual representations of the Museum artifacts, scatter them around or tidy them in the right spots, or swap them with other players. The analysis of ...

If I had chosen to speak Chinese to my daughter instead of English, she would have grown up speaking differently than she does now. If I had chosen to speak to her only with loud music in the background, then it would be no surprise if her language development was delayed. And I wouldn't expect much better results if I had only spoken to her when she was engrossed in some other activity. This i...

In October 1994 Seiberg-Witten invariants entered in 4-manifold theory with a big bang. Not only did these invariants tidy up the Gauge Theory, but they also gave some exciting new results on topology of smooth 4-manifolds. These notes grew out of the lectures I have given in learning seminars at MPI in Bonn, and METU in Ankara on this subject. The main goal of these notes is not to survey the ...

pumose To compare the efficacy of topical indomethicin, dicMenac and ketorolac as pain relief following excimer laser P.R.K. &&Q&s Double masked, random&d trial involving 360 patients. Au patients rece.ived a standard regime of one of the trial dmgs and chloramphenicol ointment to be used four times daily for 3 days.

A graph $G$ is a $B_0$-VPG if one can associate path on rectangular grid with each vertex such that two vertices are adjacent and only the corresponding paths intersect at least grid-point. contact it admitting representation no crossing sharing an edge of grid. In this paper, we present minimal forbidden induced subgraph characterisation graphs within four special classes: chordal graphs, tree...
