All genes in the S. cerevisiae genome were classified into periodic or not periodic for each of the synchronization experiments of Spellman et al. [2].
For each step of synchronization, the cells were incubated in 40 µM BrdU, trypsinized and cell suspensions were centrifuged at 3,000xg for 5 min, fixed in cold ethanol 70°at -20°C for 1 h.
For each step of synchronization, the cells were incubated in 40 µM BrdU, trypsinized and cell suspensions were centrifuged at 3,000 x g for 5 min, followed by fixation in ethanol at -20°C for 1 h.
The goal is to share the network-wide synchronization responsibility between the mesh coordinator and the synchronizers of each region for future synchronization actions.
The total battery consumption for a CN for synchronization is 446.03 nAh over 16 minutes.
After reaching 30% confluence, the cells were treated with DMEM without FBS for 24 h for synchronization.
For both synchronization strategies, each culture was washed and then shifted to a semi-permissive temperature (see Materials and Methods) in fresh medium supplemented with nocodazole to synchronize the cultures in the M-phase portion of the cell cycle.
We consider the IEEE 802.15.4 MAC protocol that operates in the beacon mode [23], where a PAN coordinator periodically sends the beacon for synchronization and each ZigBee node competes with others for transmission during the contention access period (CAP) by using the slotted CSMA/CA protocol.
All nodes must rely on a global clock for synchronization, and each node has its own reserved time slot to transmit with a fixed length, which makes this scheme unsuitable for variable length packets or event/bursty traffic.
For BAN time synchronization, in each period, a CN needs to be active a minimum of for all u seconds, where is given by (11).
In the context of CDMA systems, the most remarkable property is the two valued auto-correlation profile provided by an m-sequence that allows for a precise synchronization of each user at the receiver.
