This paper presents a new technique for detecting and extracting lists of structured records from Web pages. With respect to most of the state-of-the-art systems, our approach is capable of detecting nested data structures (sublists) and it also incorporates some heuristics to delete unwanted content such as banners and navigation menus from the data region. This article also describes the expe...

iintroduction: repetitive transcranial magnetic stimulation (rtms) modulates the excitability of cortical neural networks. the effect of rtms on excitability of cortical networks depends on its frequency. according to the previous reports, a distinction is made between low (<1hz) and high frequencies of rtms. low frequencies of rtms inhibit seizure but high frequencies increase it. in the curre...

The planar graph representing the truncated icosahedron is a cubic graph with 60 vertices and 90 edges. The computation of the chromatic polynomial of this graph is computed by enhancing the algorithm based on the classical Delete-Contract theorem as well as finding approaches for substantially modifying a computation tree during computation. The result itself is an interesting example of the t...

 When an alternating electric current flows through a conductor (wire), Electric-E and Magnetic-H fields are created around the conductor.  If the length of the conductor is very short compared to a wavelength (<< λ/4), the electric and magnetic fields will decrease dramatically within a distance of one or two wavelengths.  However, as the conductor is lengthened, the intensity of the fields...

abstract introduction: scl-90-r inventory is used for screening and assessing effect of some treatment. its sensitivity depended on environmental factors there are many shortcomings of its normalization in our community. objective: to normalize scl-90-r inventory in guilan high-school students in the years of 2003-2004. materials and methods: in a cross-sectional study, 4015 subjects were selec...
