Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...

Space Division Multiple Access (SDMA) for Robust Ad hoc Vehicle Communication Networks

This paper proposes a novel robust and self-organizing architecture for mobile ad hoc networks. The proposed architecture, space division multiple access (SDMA), relies on user position information and provides users access to the communication channel based on their spatial locations. SDMA divides the geographical space, where the users are located, into smaller spaces. The key element of the ...
