Background: Clinical remission is an attainable goal for Rheumatoid Arthritis (RA). However, data on RA rates in Asia-Pacific region are lacking. We conducted a cross-sectional study to evaluate the clinical status and associated factors patients region. Methods: receiving standard care were enrolled consecutively from 17 sites 11 countries. Data collected on-site by rheumatologists with sta...

We study the class of polynomial threshold functions using harmonic analysis and apply the results to derive lower bounds related to ACo functions. A Boolean function is polynomial threshold if it can be represented as a sign function of a sparse polynomial (one that consists of a polynomial number of terms). Our main result is that the class of polynomial threshold functions can be characteriz...

The next generation geometric modeling systems have higher requirements on the reliability and the efficiency of Boolean operations. The two parts of these technical reports describe the details of the nonlinear intersection algorithms developed at EDRC. The prototype of the algorithms has been shown to be robust, accurate, and efficient, without the overhead of subdivision. The first part of t...

in order to study the relationship between random boolean sets and some explanatory variables, this paper introduces a propagation model. this model can be applied when corresponding poisson process of the boolean model is related to explanatory variables and the random grains are not affected by these variables. an approximation for the likelihood is used to find pseudo-maximum likelihood esti...
