We describe steps required for realizing QoS for the metro Ethernet services, including classification of Customer-VLAN (C-VLAN) traffic, relevant traffic contract specifications per C-VLAN at the User to Network Interface (UNI), appropriate buffer management and scheduling of the queues at the nodes, and admission control and traffic engineering geared towards multipoint services. General func...

We analyze the impact of China's massive urban-transformation process on productivity spillovers for east-coast electrical apparatus sector by combining sub-prefecture-level population census data in 2000 and 2010 with detailed firm-level from 1999 to 2007. At sub-prefecture level, we identify three types regions (metro-core, metro-ring, non-metro) develop urban transformation measures (moderni...

We present family metro maps as a new approach to visualize the relations between multiple related families. A is represented by line, where parents are end nodes and children intermediate nodes. introduce trees rooted binary consider problem of automatically drawing map for given tree without crossing line segments, successive placed at equal distances. The inter-node distance may be chosen de...

In this paper, we consider a WDM metro ring architecture with optical burst switching. Several access protocols are proposed and their performance is analyzed by simulation.

Objective: To apply the principles of the Metro-ticket paradigm to develop a prognostic model for patients undergoing hepatic resection of colorectal liver metastasis (CRLM). Background: Whereas the hepatocellular ‘‘Metro-ticket’’ prognostic tool utilizes a continuum of tumor size and number, a similar concept of a CRLM Metro-ticket paradigm has not been investigated. Methods: Tumor Burden Scor...
