Structure and evolution of online social relationships: Heterogeneity in warm discussions
K. -I. Goh, Y. -H. Eom, H. Jeong +2
With the advancement in the information age, people are using electronic media more frequently for communications, and social relationships are also increasingly resorting to onlin…
Emerging behavior in electronic bidding
I. Yang, H. Jeong, B. Kahng +1
We characterize the statistical properties of a large number of agents on two major online auction sites. The measurements indicate that the total number of bids placed in a single…
Robustness of the in-degree exponent for the world-wide web
B. Kahng, Y. Park, H. Jeong
We consider a stochastic model for directed scale-free networks following power-laws in the degree distributions in both incoming and outgoing directions. In our model, the number…
Facet Formation in the Negative Quenched Kardar-Parisi-Zhang Equation
H. Jeong, B. Kahng, D. Kim
The quenched Kardar-Parisi-Zhang (QKPZ) equation with negative non-linear term shows a first order pinning-depinning (PD) transition as the driving force is varied. We study th…
Anisotropic Surface Growth Model in Disordered Media
HaWoong Jeong, ByungNam Kahng, Doochul Kim
We introduce a self-organized surface growth model in 2+1 dimensions with anisotropic avalanche process, which is expected to be in the universality class of the anisotropic quench…
Renormalization group analysis of the anisotropic Kardar-Parasi-Zhang equation with spatially correlated noise
H. Jeong, B. Kahng, D. Kim
We analyze the anisotropic Kardar-Parisi-Zhang equation in general substrate dimensions with spatially correlated noise, and $\langle\ti…
Dynamics of Toom interface in three dimensions
H. Jeong, B. Kahng, D. Kim
We introduce a novel three dimensional Toom model on bcc lattice, and study its physical properties. In low-noise limit, the model leads to an effective solid-on-solid-type model,…
