Tiny optical cavities quantum networks
2020/4/10
Engineers at Caltech have shown that atoms in optical cavities -- tiny boxes for light -- could lead to the creation of a quantum internet. Their National Science Foundation-funded work...
On the SOA-based MZI all-optical logic gates for all-optical networks
Optical communication All-optical AND gate All-optical logic device Semiconductor optical amplifier Mach-Zehnder interferometer
2012/5/17
In this paper, an all-optical logic scheme which exploits the cross-phase modulation (XPM) effect in semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI), is proposed, perfor...
Non-Universality in Semi-Directed Barabasi-Albert Networks
General BA directed BA undirected BA Neighbors Fortran programs
2012/5/17
In usual scale-free networks of Barabasi-Albert type, a newly added node selects randomly m neighbors from the already existing network nodes, proportionally to the number of links these had before. T...
Optimal box-covering algorithm for fractal dimension of complex networks
Optimal box-covering algorithm fractal dimension complex networks Computational Physics
2012/4/24
The self-similarity of complex networks is typically investigated through computational algorithms the primary task of which is to cover the structure with a minimal number of boxes. Here we introduce...
Opinion formation in time-varying social networks: The case of Naming Game
Opinion formation time-varying social networks The case of Naming Game Social and Information Networks
2012/4/19
We study the dynamics of the Naming Game as an opinion formation model on time-varying social networks. This agent-based model captures the essential features of the agreement dynamics by means of a m...
Epidemic Variability in Hierarchical Geographical Networks with Human Activity Patterns
Epidemic Variability Hierarchical Geographical Networks Human Activity Patterns Social and Information Networks
2012/4/19
Recently, some studies have revealed that non-Poissonian statistics of human behaviors stem from the hierarchical geographical network structure. On this view, we focus on epidemic spreading in the hi...
Variability of Contact Process in Complex Networks
Variability of Contact Process Complex Networks Social and Information Networks
2012/4/19
We study numerically how the structures of distinct networks influence the epidemic dynamics in contact process. We first find that the variability difference between homogeneous and heterogeneous net...
An equation-free approach to coarse-graining the dynamics of networks
equation-free approach coarse-graining dynamics of networks
2012/2/29
We propose and illustrate an approach to coarse-graining the dynamics of evolving networks (networks whose connectivity changes dynamically). The approach is based on the equation-free framework: shor...
A periodic add/drop system in a fiber ring network was investigated using a reconfigurable optical add/drop multiplexer (ROADM) in a re-circulating fiber loop. After seven cascaded add/drop nodes at e...
We study the realizability of scale free-networks with a given degree sequence, showing that the fraction of realizable sequences undergoes two first-order transitions at the values 0 and 2 of the pow...
Assessing the consistency of community structure in complex networks
community structure complex networks
2011/9/9
In recent years, community structure has emerged as a key component of complex network analysis.As more data has been collected, researchers have begun investigating changing community structure acros...
On the Non-Progressive Spread of Influence through Social Networks
Non-Progressive Social Networks
2011/9/14
The spread of in uence in social networks is studied in two main categories: the progressive model and the non-progressive model (see e.g. the seminal work of Kempe, Kleinberg, and Tardos in KDD 2003)...
Structural Analysis of Laplacian Spectral Properties with Application to Electric Transmission Networks
Laplacian Spectral Properties Electric Transmission Networks Optimization and Control
2011/8/18
Abstract: The spectrum of the Laplacian matrix of a network plays a key role in a wide range of dynamical problems associated with the network, from transient stability analysis of power networks to d...
Mandelbrot Law of Evolving Networks
Mandelbrot Law Evolving Networks Degree distributions power-law exponent
2011/8/11
Abstract: Degree distributions of many real networks are known to follow the Mandelbrot law, which can be considered as an extension of the power law that determined by not only the power-law exponent...
Two-Photon Exchange Effect Studied with Neural Networks

2011/7/21
The novel approach to the extraction of the two-photon exchange (TPE) correction from the elastic $ep$ scattering data is presented. The Bayesian framework for the neural networks is adapted.
