Location-areas is a popular location management scheme in cellular networks. In the location areas scheme, a service area is partitioned into location areas, each consisting of contiguous cells. A mobile terminal updates its location whenever it moves into a cell that belongs to a new location area. However, no matter how the location areas are designed, the ping-pong location update effect exi...
The ping-pong model for the red cell anion exchange system postulates that the transport protein band 3 can exist in two different conformations, one in which the transport site faces the cytoplasm (Ei) and another in which it faces the outside medium (Eo). This model predicts that an increase in intracellular chloride should increase the fraction of sites in the outward-facing, unloaded form (...
Security of the "ping-pong" quantum communication protocol recently proposed by Boström and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]] is analyzed in the case of considerable quantum channel losses. The eavesdropping scheme is presented, which reveals that the ping-pong protocol is not secure for transmission efficiencies lower than 60%. Our scheme induces 50% losses, which, however, can b...
in this study, decolorization of the diazo dye, reactive black 5 (rb5) in a coprinus cinereus peroxidase-catalyzed reaction has been investigated. a bisubstate kinetic model for the reaction rate based on the ping-pong mechanism was assumed for the enzymatic decolorization. experimentswere conducted at different rb5 and hydrogen peroxideconcentrations in a batch mannerto estimate the intrinsic ...
In this paper, the convergence behaviour of linear parallel interference cancellation is investigated. Especially the so-called ping-pong effect where the bit error rate performance is found to oscillate between two different convergence patterns is studied in detail. This effect is shown to be a direct consequence of the extreme eigenvalues of the correlation matrix, allowing for an analytical...
