OBJECTIVES to show whether or not the pricing system given has had the desired result, we review pricing and reimbursement systems of generics in some of the EU countries a...

philosophy of mathematics suited well the ‘‘general emphasisin later nineteenth-century mathematics on revisiting foundationalquestions’’ (p. 61). Pure geometry as it emerged from Frege, Paschand Hilbert, provided a diagram-free, purely sentential notion ofproof, which has lasted unto our own day.In the second, and greater, part of the book, Greaves traces outthe interre...

Have Pentaquark States Been Seen?

The status of the search for pentaquark baryon states is reviewed in light of new results from the first two dedicated experiments from CLAS at Jefferson Lab and of new analyses from several labs on the Θ + (1540). Evidence for and against the heavier pentaquark states, the Ξ(1862) and the Θ 0 c (3100) observed at CERN and at HERA, respectively, are also discussed. I conclude that the evidence ...
