The possibility offered by the current technology to collect and store data sets regarding public places located on Earth globe is posing new challenges, as far integration of these concerned. Analysts usually need perform such an from scratch, without performing complex long preprocessing or data-cleaning tasks, well training activities that require tedious labeling data; furthermore, analysts...

This paper presents new evidence on international financial market integration using stock analyst earnings forecasts from 37 countries around the world. By examining cash flow and discount rate news co-movements, we find that the financial and economic aspects of global market integration have diverged over time as financial integration has developed particularly more rapidly than economic int...

in this paper, we present some inequalities for the co-pi index involving the some topological indices, the number of vertices and edges, and the maximum degree. after that, we give a result for trees. in addition, we give some inequalities for the largest eigenvalue of the co-pi matrix of g.

in this paper, we introduce the notion of primal strong co-ideals and give some results involving them. it is shown thatsubtractive strong co-ideals are intersection of all primal strong co-ideals that contain them. also we prove that the representation of strong co-ideals as reduced intersections of primal strong co-ideals is unique.

Abstract The order of integration is valid to characterize linear processes; but it is not appropriate for non-linear worlds. We propose the concept of summability (a re-scaled partial sum of the process being Op(1)) to handle non-linearities. The paper shows that this new concept, S (δ): (i) generalizes I (δ); (ii) measures the degree of persistence as well as of the evolution of the variance;...

Background Transposon systems mediate stable integration of exogenous DNA elements into a host cell genome, and have been successfully used in mammalian cells for the generation of stable cell lines. The piggyBac (PB) transposon system has been shown to have several advantages over the other transposon system available [1-3]. It has also been shown to generate stable cell lines at significantly...
