This paper deals with the distributed queue dual bus (DQDB) (IEEE 802.6) network, and makes two independent contributions. First, the unfairness problem of DQDB is addressed, and several alternative solutions that can improve the network's fairness are proposed. They include (1) the proportional assignment scheme (PR); (2) the (multiple-request)(More)
Notch pathway is a well-known factor in the development of lymphoid lineage. However, its role in the myeloid lineage has remained ambiguous. We looked into the effect of Notch1 on the megakaryocytic lineage commitment and found an increase in megakaryocyte-specific lineage markers upon transfection with Notch1 intracellular domain (NICD). This effect was(More)
A new, fault-tolerant, scalable, and, modular virtual topology for lightwave networks employing wavelength division multiplexing is proposed. The proposed architecture is based on hypercube connected ring structure that enjoys the rich topological properties of hypercube, but it also overcomes one of its drawback. In a hypercube, the nodal degree increases(More)
The capabilities of emerging optical technology, viz. dense wavelength division multiplexing (WDM) and tunable optical transmitters and receivers (transceivers) can be exploited to construct lightwave networks , as follows. First, by employing WDM, the huge optical bandwidth (in the order of Terahertz) is partitioned into a number of smaller capacity(More)
