Identity and search in social networks
- Science
, 2002
"... Social networks have the surprising property of being “searchable”: ordinary people are capable of directing messages through their network of acquaintances to reach a specific but distant target person in only a few steps. We present a model that offers an explanation of social network searchabilit ..."

Peer reviewed
"... The asteroid and comet impact peril appears to be, in several respects, more momentous than environmental hazards such as global warming. Building on Gregory Canavan’s analysis that he derived from impact frequency data, an estimate in the order of $40 billion is obtainable as the present value of t ..."

when, as Martin Weitzman urges, the lowest possible discount rate is used for distant future losses. Separating extinction level threats from the ordinary analytics of risks in general also implies domination by the asteroid threat over threats such as the greenhouse effect from anthropogenic carbon

Optimal super-peer selection for large-scale p2p system
- In Proc. ICHIT
, 2006
"... The peer-to-peer (P2P) systems have grown significantly over the last few years due to their potential for sharing various resources. Unstructured hybrid P2P system can improve the performance of the entire network and system using SP (Super-peer), which has the responsibility for query processing i ..."

instead of OPs (Ordinary-Peer). In these systems, selecting the best SP to join is an important problem, but it is difficult to choose the optimal SP by the various reasons such as heterogeneous capacity, content similarity and dynamic capacity change. In this paper, we present the SP selection’s problem
Exploiting heterogeneity in peer-to-peer systems using gradient topologies
, 2009
"... A peer-to-peer system can be defined as an overlay network built by a set of nodes on top of a physical network infrastructure and its operating protocols, such as the Internet. In a peer-to-peer network, each node maintains a limited number of connections with other nodes, called peers, and the gra ..."

an efficient, decentralised super-peer election algorithm. In many systems, super-peers are selected manually
Children's understanding of ordinary and extraordinary minds
- Child Development
, 2010
"... How and when do children develop an understanding of extraordinary mental capacities? The current study tested 56 preschoolers on false-belief and knowledge-ignorance tasks about the mental states of contrasting agents-some agents were ordinary humans, some had exceptional perceptual capacities, an ..."

, and others possessed extraordinary mental capacities. Results indicated that, in contrast to younger and older peers, children within a specific age range reliably attributed fallible, human-like capacities to ordinary humans and to several special agents (including God) for both tasks. These data lend
Dynamics of heterogeneous peer-to-peer networks
"... Abstract- The most tractable models of population dynamics in peer-to-peer file sharing systems apply to a single class of peers with homogeneous network access parameters. When upload bandwidths are heterogeneous, reciprocity mechanisms lead to non-uniform download rates and a more complex multi-c ..."

For an ordinary differential equation model of the multi-class peer populations, we characterize the equilibrium and establish its global
Cluster Computing on the Fly: Resource Discovery in a Cycle Sharing Peer-to-Peer System
- In IEEE Intl. Workshop on Global and Peer-to-Peer Computing
, 2004

Abstract—Peer-to-peer computing, the harnessing of idle compute cycles throughout the Internet, offers exciting new research challenges in the converging domains of networking and distributed computing. Our system, Cluster Computing on the Fly, seeks to harvest cycles from ordinary users in an open ..."

Sbarc: A supernode based peer-to-peer file sharing system
- In Eighth IEEE International Symposium on Computers and Communications, Kemer-Antalya
, 2003
"... Peer-to-Peer (P2P) system has become one of the hottest research topics, its excellent characteristics of fully decentralized control and self-organizing make it attractive for some particular applications. However, it faces more technical problems than client/server architecture. In this paper, we ..."

propose SBARC, a new P2P file sharing system which takes into account the tremendous resource differences among peers to improve system performance. SBARC divides the peers into supernodes and ordinary nodes and most workloads are taken on supernodes. The main contributions of SBARC are (1). A supernode
