objectives: presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (scc). this study was designed to assess the diagnostic accuracy of computed tomography (ct) scan for detection of cervical lymph node metastasis in oral scc in comparison with histopathological analysis after neck dissection methods: in th...

We present a distributed protocol for maintaining a maximum flow spanning tree in a network, with a designated node as the root of the tree. This maximum flow spanning tree can be used to route the allocation of new virtual circuits whose destination is the designated node. As virtual circuits are allocated and removed, the available capacity of the channels in the network changes, causing the ...

We consider the problem of finding the minimum capacity cut in a directed network G with n nodes. This problem has applications to network reliability and survivability and is useful in subroutines for other network optimization problems. One can use a maximum flow problem to find a minimum cut separating a designated source node s from a designated sink node t, and by varying the sink node one...

The three flow-control techniques introduced in this paper are backpressure flow control, alpha scheduling, and balanced injection. Our variations on backpressure flow control essures that all the buffers in a node are not filled with one particular category of packet, such as those destined for the same node, so that buffers are available for other packets. Alpha scheduling exploits the distin...

The standard formulation of a block-centered finite-difference model, such as MODFLOW, uses the center of the cell as the location of a cell node. Simulations of a dynamic water table can be improved if the node of a cell containing the water table is located at the water table rather than at the center of the cell. The LPF package of MOD-FLOW-2000 was changed to position a cell's node at the w...

This paper focuses on flow control in high-speed networks. Each node in a network handles its local traffic flow only on the basis of the information it is aware of, but it is preferable that the decision-making of each node leads to high performance of the whole network. To this end, we investigate the relationship between the flow control mechanism of each node and network performance. We con...

form suitable for the transform centre. An efferent stream, on the other hand, is a string of processes which convert output data from the transform centre into a more physical form suitable for output to the real world. We can know for sure that some nodes must belong to the transform centre. They satisfy either of the following conditions: (a) The node name contains a verb such as subtract wh...

1 Maximum flow In the maximum flow problem, we are given a directed graph with a distinguished source node and a distinguished sink node. In addition, each edge has a capacity, which is the largest amount of flow that can go over this edge. Our goal is to route as much flow from the source to the sink as we can, along the edges of the graph. For example, consider the directed graph with capacit...

Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...
