Data mining is a collection of analytical techniques to uncover new trends and patterns in massive databases. These data mining techniques stress visualization to thoroughly study the structure of data and to check the validity of the statistical model fit which leads to proactive decision making. Discriminant analysis is one of the data mining tools used to discriminate a single classification...
a new guideline for proper allocation of multipoles in the multiple multipole method (mmp) is proposed. in an ‘a posteriori’ approach, subspace fitting (ssf) is used to find the best location of multipole expansions for the two dimensional dielectric scattering problem. it is shown that the best location of multipole expansions (regarding their global approximating power) coincides with the med...
background: it has been suggested that nutrition might play a role in the etiology of multiple sclerosis (ms). however, dietary patterns associated with ms risk are unknown. this study was conducted to compare the dietary patterns of patients with ms and healthy controls to find the relationship between dietary patterns and ms. methods: usual dietary intake of 75 women with relapsing/remitting ...
A new study in which rats had to discriminate odors according to whether they were novel for a particular environmental context has found that they can accurately discriminate a large number of odors and multiple context transitions, suggesting that they are able to form and remember multiple episodic memories.

AIMS For the standardization of flow-mediated vasodilatation (FMD) assessment as a clinical tool, validation of its reliability across multiple institutions and the establishment of normal/reference values based on reliable data from multiple institutions are needed. METHODS AND RESULTS In Study 1, assessment of FMD (scan recording and analysis) using an ultrasonographic semi-automatic measur...
purpose: to determine the frequency and severity of retinopathy of prematurity (rop) among singleton and multiple-birth neonates referred to farabi eye hospital, tehran-iran. methods: we reviewed the records of 99 consecutive neonates from multiple-gestation pregnancies including 68 twins, 26 triplets and 5 quadruplets who were screened for rop during 2002-2004. the frequency, severity and risk...
