Your Friends Have More Friends Than You Do: Identifying Influential Mobile Users Through Random Walks
Influential mobile users random walks distributed protocol disease control information dissemination
2016/1/23
In this paper, we study the problem of identifying influen-tial users in mobile social networks. Traditional approaches find these users through centralized algorithms on either friendship or social-c...
We describe a short signature scheme which is existentially unforgeable under a chosen message attack without using random oracles. The security of our scheme depends on a new complexity assumption we...
We present a fully secure Identity Based Encryption scheme whose proof of security does not rely on the random oracle heuristic. Security is based on the Decision Bilinear Diffie-Hellman assumption. T...
Efficient Selective Identity-Based Encryption Without Random Oracles
Random Oracles Identity-Based Encryption
2015/8/5
We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model Selective identity secure IBE is a slightly weaker security model ...
Heterogeneous Graphene Nanoribbon-CMOS Multi-State Volatile Random Access Memory Fabric
Graphene GNTRAM heterogeneous memory multistate memory graphene nanoribbons
2014/12/8
CMOS SRAM area scaling is slowing down due to several challenges faced by transistors at nanoscale such as increased leakage. This calls for new concepts and technologies to overcome CMOS scaling limi...
A Conversational Movie Search System Based on Conditional Random Fields

Efficient computation the electromagnetic propagation parabolic equation electromagnetic
2014/11/7
Efficient computation in deterministic and uncertain electromagnetic propagation environments, tackled by parabolic equation methods, is the subject of interest of this dissertation. Our work is compr...
Subset Selection for Gaussian Markov Random Fields
Subset Selection Gaussian Markov Random Fields
2012/11/26
Given a Gaussian Markov random field, we consider the problem of selecting a subset of variables to observe which minimizes the total expected squared prediction error of the unobserved variables. We ...
Analysis of complex contagions in random multiplex networks
Analysis of complex contagions random multiplex networks Social and Information Networks
2012/4/19
We study the diffusion of influence in random multiplex networks where links can be of $r$ different types, and for a given content (e.g., rumor, product, political view), each link type is associated...
The abelian sandpile model on a random binary tree
abelian sandpile model random binary tree
2012/2/24
We study the abelian sandpile model on a random binary tree. Using a transfer matrix approach introduced by Dhar & Majumdar, we prove exponential decay of correlations, and in a small supercritical re...
Freezing Transition, Characteristic Polynomials of Random Matrices, and the Riemann Zeta-Function
Freezing Transition Characteristic Polynomials Random Matrices the Riemann Zeta-Function
2012/2/24
We argue that the freezing transition scenario, previously explored in the statistical mechanics of 1/f-noise random energy models, also determines the value distribution of the maximum of the modulus...

Taming random lasers active spatial control pump
2012/2/24
Active control of the pump spatial profile is proposed to exercise control over random laser emission. We demonstrate numerically the selection of any desired lasing mode from the emission spectrum. A...
Random Partial Paired Comparison for Subjective Video Quality Assessment via HodgeRank ∗
