Litjens, R. (author), Boucherie, R.J. (author)An extensive performance evaluation is presented for a segregated and a hybrid radio resource sharing scheme in an integrated GSM/GPRS network, with a finite queue for data calls that cannot be served immediately upon arrival. Markov chain analysis is used to derive simple performance measures such as the blocking probabilities, expected channel...conference paper 2000

van Nieuw Amerongen, G.P. (author), Vermeer, M.A. (author), van Hinsbergh, V.W. (author), Gaubius Instituut TNO (author)In the present study, the roles of the small GTPase RhoA and its target Rho kinase in endothelial permeability were investigated in vitro. We have shown previously that, in addition to a rise in the intracellular Ca(2+) concentration ([Ca(2+)](i)), RhoA is involved in the prolonged thrombin-induced barrier dysfunction. To study the role of RhoA...article 2000
