Introduction The diffusion restrictions present in biological tissue result in deviations from the Gaussian propagator shape, which can be quantified using the apparent kurtosis Kapp [1]. Kapp is defined by eq. 1, where <φ > is the expectation value of the n-th power of the spin phase, and it appears in the expansion of the logarithmic signal in powers of b (eq. 2). [ ] 2); ( ... 6 ) 0 ( ) ( ln...

geomorphologic landforms associated with tourism and development has been considered by many researchers in recent years. geomorphologic landforms which have values and capabilities, considered in context of tourism, known as geomorphosite and are studied in geomorphotourism approach. in this paper, we used landsat satellite imageries, geological and topographic maps, data obtained by field obs...

Eccentric connectivity index has been found to have a low degeneracy and hence a significant potential of predicting biological activity of certain classes of chemical compounds. We present here explicit formulas for eccentric connectivity index of various families of graphs. We also show that the eccentric connectivity index grows at most polynomially with the number of vertices and determine ...
