Many pathologic entities can produce a painful total knee replacement (TKR) that may lead to potential prosthetic failure. Polyethylene insert dissociation from the tibial baseplate has been described most frequently after mobile-bearing and cruciate-retaining TKRs. However, only 3 tibial insert dislocations in primary fixed-bearing High-Flex posterior-stabilized TKRs have been reported. We pre...

For a polygonal linkage, we produce a fast navigation algorithm on its configuration space. The basic idea is to approximate the configuration space by the vertex-edge graph of its cell decomposition discovered by the first author. The algorithm has three aspects: (1) the number of navigation steps does not exceed 15 (independent of the linkage), (2) each step is a disguised flex of a quadrilat...

The oldest of all the shaft specifications is flex. Once the production problems had been overcome which enabled steel shafts to become a reality, early steel shaft manufacturers began to experiment with producing shafts, which possessed different amounts of resistance to bending. Through the 70 years of shaft design that have followed the introduction of the steel shaft, companies have produce...

The flexible goal adjustment (FLEX) and tenacious goal pursuit (TEN) scales are used regularly in aging research. The current study examined their validity in a sample of 517 women (30–75 years) in multiple ways. Overall, the findings show that the scales do not clearly distinguish between FLEX and TEN. The direction in which the items were formulated was just as important as what was being mea...

We describe Flex-GP, which we believe to be the first largescale genetic programming cloud computing system. We took advantage of existing software and selected a socket-based, client-server architecture and an island-based distribution model. We developed core components required for deployment on Amazon EC2. Scaling the system to hundreds of nodes presented several unexpected challenges and r...

Abstract: As a result of the continuing evolution of z/Series processors, anever wideninggap has developed between the minimum size of IBM’s entry level processors and the MIPS requirements of small z/OS software developers as well as the thousands of VSE and VM installations. This paper explores the architecture of the FLEX-ES product from Fundamental Software Incorporated (FSI) as delivered i...

We present a numerical solution of the parquet approximation, a conserving diagrammatic approach which is self-consistent at both the single-particle and the two-particle levels. The fully irreducible vertex is approximated by the bare interaction thus producing the simplest approximation that one can perform with the set of equations involved in the formalism. The method is applied to the Hubb...
