Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centra...

This paper uses Data Envelopment Analysis and econometric methods to evaluate the efficiency of Turkish secondary education. It identifies scale diseconomies and relates them to the underlying structural characteristics of the system. Some ideas on improving performance are offered. The role of heterogeneity and centralization is highlighted. Heterogeneity is modeled as an undesirable measure. ...

The state-of-the-art OpenFlow technology only partially realized SDN vision of abstraction and centralization for packet forwarding in switches. OpenFlow/P4 falls short in implementing middlebox functionalities due to the fundamental limitation in its match-action abstraction. In this paper, we advocate the vision of Software-Defined Middleboxes (SDM) to realize abstraction and centralization f...
