Abstract Complex networks, which constitute the main subject of network science, have been wide and extensively adopted for representing, characterizing, modeling an ample range structures phenomena from both theoretical applied perspectives. The present work describes application real-valued Jaccard coincidence similarity indices translating generic datasets into networks. More specifically, t...

The connection between random matrix theory and the Riemann zeta function was established in 1973 when Montgomery, who had conjectured the 2-point correlations of the Riemann zeros, and Dyson, who was interested in similar statistics of the eigenvalues of ensembles of unitary matrices, realized that the formulae they had discovered independently were in fact identical in a natural asymptotic li...

The reports on familial Down's syndrome (mongolism) date in the medical literature from the 20th years of this century. Familial Down's syndrome is now well-described event but relatively rare. Penrose states that pairs of affected sibs appear about once for every 100 single cases of mongolism collected at random (quoted by Soltan et al. 1964). About two-thirds of the mongoloids are close relat...

RADIATION SAFETY The radioactive sources used in this experiment are only a few microcuries in strength, and they are all sealed, so they actually pose no significant health hazard. However we will follow good safety procedure. Horseplay involving the sources is forbidden. While the sources are not dangerous, like any radioactive source they should be treated with respect and properly handled. ...

Some fixed and coincidence point theorems for R-weakly commuting mappings are obtained. Our results generalize some recent results of Daffer and Kaneko [2] and many of the others. AMS Mathematics Subject Classification (2000): 54H25

This paper establishes one common coincident point theorem and three unique common fixed point theorems for four self-maps in D-metric spaces, which improve and generalize, significantly, the results of Dhage et al. (2003), Dhage (1999), and Rhoades (2003) under weaker assumption using a more general contractive condition. An example, in support of these theorems, has also been constructed. All...
