A graph modification approach for finding core–periphery structures in protein interaction networks

by Sharon Bruckner , Falk Hüffner, Christian Komusiewicz , 2015
"... The core–periphery model for protein interaction (PPI) networks assumes that protein complexes in these networks consist of a dense core and a possibly sparse periphery that is adjacent to vertices in the core of the complex. In this work, we aim at uncovering a global core–periphery structure for ..."

Core and periphery in free/libre and open source software team communications

by Kevin Crowston, Kangning Wei, Qing Li, James Howison - In Proceedings of the 39th Hawai’i International Conference on System System
"... The concept of the core group of developers is important and often discussed in empirical studies of FLOSS projects. This paper examines the question, “how does one empirically distinguish the core? ” Being able to identify the core members of a FLOSS development project is important because many of ..."

as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core

Core-halo instability in dynamical systems

by Seth Lloyd
"... This paper proves an instability theorem for dynamical systems. As one adds inter-actions between subystems in a complex system, structured or random, a threshold of connectivity is reached beyond which the overall dynamics inevitably goes un-stable. The threshold occurs at the point at which flows ..."

and interactions between subsystems (‘surface ’ effects) overwhelm internal stabilizing dynamics (‘volume ’ ef-fects). The theorem is used to identify instability thresholds in systems that possess a core-halo or core-periphery structure, including the gravo-thermal catastrophe – i.e., star collapse and explosion

The cytoskeleton of the resting human blood platelet: structure of the membrane skeleton and its attachment to actin filaments

by John H. Hartwig, Michelle Desisto - J. Cell , 1991
"... Abstract. We used high-resolution EM and immunocytochemistry in combination with different specimen preparation techniques to resolve the ultrastructure of the resting platelet cytoskeleton. The periphery of the cytoskeleton, an electron-dense subplasmalemmal region in thin section electron microgra ..."

micrographs, is a tightly woven planar sheet composed of a spectrin-rich network whose interstices contain GPlb/IX-actin-binding protein (ABP) complexes. This membrane skeleton connects to a system of curved actin filaments (F-actin) that emanate from a central oval core of F-actin crosslinked by ABE

This paper aims to demonstrate that ties obtained by mining e-mails archives do not necessarily provide a complete and realistic approximation of interactions by other communication media. The results of our project indicate that factors such as co-location and the nature of working relati ..."

RESEARCH ARTICLE Unifying Inference of Meso-Scale Structures in Networks

"... Networks are among the most prevalent formal representations in scientific studies, employed to depict interactions between objects such as molecules, neuronal clusters, or social groups. Studies performed at meso-scale that involve grouping of objects based on their distinctive interaction patterns ..."
