The spectral closeness of a graph G is defined as the radius matrix , whose ( u v )-entry for vertex and 2 − d u,v ) if ≠ 0 otherwise, where distance between in . residual nontrivial minimum subgraphs with one deleted. We propose local grafting operations that decrease or increase determine those graphs uniquely minimize and/or maximize some families graphs. also discuss extremal properties clo...

Real technological, social and biological networks evolve over time. Predicting their future topology has applications to epidemiology, targetedmarketing, network reliability and routing in ad hoc and peer-to-peer networks. The key problem for such applications is usually to identify thenodes thatwill be inmore important positions in the future. Previous researchers had used ad hoc prediction f...

The co-immobilization of Aspergillus niger glucose oxidase (GOD) with bovine liver catalase (CAT) onto florisil (magnesium silicate-based porous carrier) was investigated to improve the catalytic efficiency of GOD against H2O2 inactivation. The effect of the amount of bound CAT on the GOD activity was also studied for 12 different initial combinations of GOD and CAT, using simultaneous and sequ...

Based on a critical analysis of the periodicals SvobodnĂ˝ zednář and Die drei Ringe, authors article examine attitudes Czechoslovak Free Masons towards question evolutionary origins human being Darwinism in period 1925‒1938.

The standard view in epistemology is that propositional knowledge entails belief. Positive arguments are seldom given for this entailment thesis, however; instead, its truth is typically assumed. Against the entailment thesis, Myers-Schulz and Schwitzgebel (forthcoming) report that a non trivial percentage of people think that there can be propositional knowledge without belief. In this paper, ...

One of the most important research topics about complex networks
 is examination their vulnerability. Therefore, there are many studies
 in literature analyzing robustness and reliability using graph theoretical parameters. Among these parameters, centrality
 parameters play an role.The closeness its derivatives
 widely discussed. In this study, parameter more sensitive&#x0D...
