Relevance and importance are the main factors when humans build network connections. We propose an evolutionary network model based on preferential attachment(PA) considering these factors. We analyze and compute several important features of the network class generated by this algorithm including scale free degree distribution, high clustering coefficient, small world property and core-periphe...

We propose a statistical model for graphs with core-periphery structure. give precise notion of what it means graph to have this structure, based on the sparsity properties subgraphs core and periphery nodes. present class sparse such properties, provide methods simulate from class, perform posterior inference. demonstrate that our can detect structure in simulated real-world networks.

Taiwan economy has always been export-oriented, creating tightly-linked industrial chains between cross-straits companies tightly. Understanding the influence of transforming industrial patterns of major economic entities would be critical for long-term cooperative small economic entities (countries or regions) in the periphery. The author of this paper has thus analyzed the influences and ...

Sadamori Kojaku and Naoki Masuda∗ Department of Engineering Mathematics, Merchant Venturers Building, University of Bristol, Woodland Road, Clifton, Bristol BS8 1UB, United Kingdom Abstract A network with core-periphery structure consists of core nodes that are densely interconnected. In contrast to community structure, which is a different meso-scale structure of networks, core nodes can be co...

A model of foveal achromatic and chromatic sensitivity [Vision Res. 36, 1597 (1996)] was extended to the peripheral visual field. Threshold-versus-illuminance functions were analyzed to determine effects of eccentricity on absolute thresholds and gain constants of chromatic and luminance mechanisms. The resulting peripheral model successfully predicted peripheral contrast sensitivity as a funct...

Results. For the spherical surface, both curvature-based paraxial power approximations were uniform over the entire surface because curvature is constant. However, the corneal refractive power increased from center to periphery, demonstrating the known phenomenon of spherical aberration. For the ellipsoids, which have been shown to model the human cornea, curvature-based power approximations de...

Abstract In a complex network, the core component with interesting structures is usually hidden within noninformative connections. The noises and bias introduced by can obscure salient structure limit many network modeling procedures’ effectiveness. This paper introduces novel core–periphery model for periphery of networks without imposing specific form core. We propose spectral algorithms iden...
