We present preliminary results of an ongoing survey to probe the physical nature of a sample of open clusters ( POCRs, Bica et al. 2001) believed to be in an advanced stage of dynamical evolution. This kind of object is very important to constrain dynamical N -body models of clusters evolution and dissolution, and to understand the formation of the Galactic field stars population. Moreover they...

Learning features from massive unlabelled data is a vast prevalent topic for highlevel tasks in many machine learning applications. The recent great improvements on benchmark data sets achieved by increasingly complex unsupervised learning methods and deep learning models with lots of parameters usually requires many tedious tricks and much expertise to tune. However, filters learned by these c...

The results of knowledge discovery in databases could vary depending on the data mining method. There are several ways to select the most appropriate data mining method dynamically. One proposed method clusters the whole domain area into “competence areas” of the methods. A metamethod is then used to decide which data mining method should be used with each database instance. However, when knowl...

We summarize the results of several experiments in applying a metamethod for formal method integration [18, 19]. We provide a small example of using an instance of integrated formal methods, and discuss properties and difficulties associated with applying the meta-method to combining and using several formal and semiformal methods.

background: this study examined the applicability of trans-theoretical model (ttm) to understand exercise behavior among female college students in hamadan university of medical sciences, iran in 2007. methods: a cross-sectional descriptive study was conducted. the dependent variables analyzed were exercise efficacy expectation, decisional balance (pros and cons). the independent variable was s...

patients with syndrome x coronary disease represent a heterogeneous group of patients. medical treatment with dilators and calcium channel blockers are not very effective. we evaluated the use of transmyocardial laser revascularization (tmlr) in treating 5 patients with this syndrome. between may 2002 to december 2005, 5 patients with cardiac syndrome x (mean age of 49.7 years) underwent tmlr. ...

leishmania is a protozoan parasite belonging to the family trypanosomatidae, which is found among 88 different countries. the parasite lives as an amastigote in vertebrate macro­phages and as a promastigote in the digestive tract of sand fly. it can be cultured in the laboratory us­ing appropriate culture media. although the sexual cycle of leishmania has not been observed during the promastigo...
