Co-Simrank is a useful Simrank-like measure of similarity based on graph structure. The existing method iteratively computes each pair of Co-Simrank score from a dot product of two Pagerank vectors, entailing O(log(1/ǫ)n3) time to compute all pairs of Co-Simranks in a graph with n nodes, to attain a desired accuracy ǫ. In this study, we devise a model, Co-Simmate, to speed up the retrieval of a...

Co-evolutionary algorithms are evolutionary algorithms in which the given individual’s fitness value estimation is made on the basis of interactions of this individual with other individuals present in the population. In this paper agent-based versions of co-operative co-evolutionary algorithms are presented and evaluated with the use of standard multi-objective test functions. The results of e...

The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670 (8) Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-member...

In this paper we investigate the effects of co-citation proximity on the quality of co-citation analysis through four experiments of co-citation instances found in full-text scientific publications. First, we compared the distributions of co-citation instances at four levels of proximity in journal articles with the traditionally used article-level co-citation counts. Second, we analyzed how co...

A four-dimensional potential energy surface (PES) for the CO dimer consisting of rigid molecules has been calculated, using a scheme that combines density functional theory to describe the monomers and symmetry adapted perturbation theory for the interaction energy (DFT-SAPT). The potential is fitted in terms of analytic functions, and the fitted potential is used to compute the lowest rovibrat...

By a generalized arc we mean a continuum with exactly two non-separating points; an arc is a metrizable generalized arc. It is well known that any two arcs are homeomorphic (to the real closed unit interval); we show that any two generalized arcs are co-elementarily equivalent, and that co-elementary images of generalized arcs are generalized arcs. We also show that if f : X → Y is a function b...

Genome-scale engineering of living organisms requires precise and economical methods to efficiently modify many loci within chromosomes. One such example is the directed integration of chemically synthesized single-stranded deoxyribonucleic acid (oligonucleotides) into the chromosome of Escherichia coli during replication. Herein, we present a general co-selection strategy in multiplex genome e...

This paper deals with Intelligent Transport Systems (ITS) and the concept of a Co-operative Transport System (CTS), in which the communication and the knowledge sharing is much more important. This distributed knowledge allows improving road transport operations more safety and efficiency. After showing some issues about development and advantages of a CTS, the communication part is discussed a...

This paper presents the integration between two types of genetic algorithm: a multi-objective genetic algorithm (MOGA) and a co-operative co-evolutionary genetic algorithm (CCGA). The resulting algorithm is referred to as a multi-objective co-operative co-evolutionary genetic algorithm or MOCCGA. The integration between the two algorithms is carried out in order to improve the performance of th...
