We present results of an extensive mapping survey of N2H (1–0) in about 60 low mass cloud cores already mapped in the NH3(1,1) inversion transition line. The survey has been carried out at the FCRAO antenna with an angular resolution of 54, about 1.5 times finer than the previous ammonia observations made at the Haystack telescope. The comparison between N2H + and NH3 maps shows strong similari...

during ornithological expedition to four provinces in the northeast and north of iran in june 2009, a total of 117 bird species belonging to 14 orders and 40 families were recorded. based on these records, eight bird species were found outside their presumed breeding range according to the available distribution maps covering iran, suggesting that updating of the distribution maps should be pro...

Abstract In this paper we first prove a nonexistence result on iterative roots, which presents several sufficient conditions for identifying self-maps arbitrary sets that have no roots of any order. Then, using result, when X is [ 0 ,</mml:mo...

We study the postcritically finite maps within the moduli space of complex polynomial dynamical systems. We characterize rational curves in the moduli space containing an infinite number of postcritically finite maps, in terms of critical orbit relations, in two settings: (1) rational curves that are polynomially parameterized; and (2) cubic polynomials defined by a given fixed point multiplier...

In a study of the velocity dispersion of molecular gas in maps of four dense cores, we Ðnd that : 3 (1) within the interiors of dense cores, the line widths are roughly constant at a value slightly but signiÐcantly higher than a purely thermal line width ; and (2) at the edges of the maps of the dense cores, it appears that the line width starts to increase. We suggest that these dense cores ar...

We present a new feature based algorithm for stereo correspondence. Most of the previous feature based methods match sparse features like edge pixels, producing only sparse disparity maps. Our algorithm detects and matches dense features between the left and right images of a stereo pair, producing a semi-dense disparity map. Our dense feature is defined with respect to both images of a stereo ...

Abstract We prove the Zariski dense orbit conjecture in positive characteristic for regular self-maps of split semiabelian varieties.

An efficient hierarchical technique is presented for obtaining dense stereo correspondence using a color image pyramid. We show that matching results of high quality are obtained when using the hierarchical chromatic Block Matching algorithm. Furthermore, we present some results for parallel implementations of the algorithm. Most stereo matching algorithms can not compute correct dense depth ma...
