—Binary search on levels (BSOL) is a decision-tree algorithm for packet classification with superior speed performance. However, the most decision-tree-based algorithms, like BSOL, may suffer from a memory explosion problem caused by filter replications. In this work, we improve the storage performance of BSOL by employing a scheme, replication control. Our(More)
—The paper illustrates that multiple access interference (MAI) can be reduced by arranging the spreading codes in multi-carrier code division multiple access (MC-CDMA) systems. An effective spreading code allocation procedure using simple least square (LS) channel estimation is presented to reduce the MAI in downlink MC-CDMA systems. Moreover, the spreading(More)
Many Bacillus subtilis strains swarm, often forming colonies with tendrils on agar medium. It is known that B. subtilis swarming requires flagella and a biosurfactant, surfactin. In this study, we find that water surface tension plays a role in swarming dynamics. B. subtilis colonies were found to contain water, and when a low amount of surfactin is(More)
