BACKGROUND Transpyloric feeding tubes (TPT) are often recommended in critically ill children. Blind tube placement, however, can be difficult, be time-consuming, and incur multiple radiation exposures. An electromagnetic device (EMD) is available for confirmation of successful placement of TPTs. We conducted a retrospective cohort study to evaluate the efficacy of an EMD for TPT placement in ch...

Programming distributed-memory machines requires careful placement of data on the nodes. This is because achieving eeciency requires balancing the computational load among the nodes and minimizing excess data movement between the nodes. Most current approaches to data placement require the programmer or compiler to place data initially and then possibly to move it explicitly during a computatio...

The basic \quadratic placement" methodology is rooted in works by Wipper et al. 36], Cheng and Kuh 8], Tsay et al. 32, 33, 34] and many others. It is also, reputedly, an approach that has been used in commercial and in-house tools for placement of standard-cell and gate-array designs. The quadratic placement methodology entails (i) solving recursively generated sparse systems of linear equation...
