Estimation of Infection Rate and Prediction of Initial Infected Individuals of COVID-19
Seo Yoon Chae, Kyoung-Eun Lee, Hyun Min Lee +6
We consider the pandemic spreading of COVID-19 for some selected countries after the outbreak of the coronavirus in Wuhan City, China. We estimated the infection rate and the initi…
Critical dynamics of the k-core pruning process
G. J. Baxter, S. N. Dorogovtsev, K. -E. Lee +2
We present the theory of the k-core pruning process (progressive removal of nodes with degree less than k) in uncorrelated random networks. We derive exact equations describing thi…
Power Law in Firms Bankruptcy
Byoung Hee Hong, Kyoung Eun Lee, Jae Woo Lee
We consider the scaling behaviors for fluctuations of the number of Korean firms bankrupted in the period from August 1 2002 to October 28 2003. We observe a power law for the dist…
Universality Class of Bak-Sneppen Model on Scale-Free Network
Kyoung Eun Lee, Byoung Hee Hong, Jae Woo Lee
We study the critical properties of the Bak-Sneppen coevolution model on scale-free networks by Monte Carlo method. We report the distribution of the avalanche size and fractal act…
Avalanche dynamics of an idealized neuron function in the brain on uncorrelated random scale-free network
Kyoung Eun Lee, Jae Woo Lee
We study a simple model for a neuron function in a collective brain system. The neural network is composed of uncorrelated random scale-free network for eliminating the degree corr…
Waiting-time distribution for a stock-market index
Jae Woo Lee, Kyoung Eun Lee, Per Arne Rikvold
We investigate the waiting-time distribution of the absolute return in the Korean stock-market index KOSPI. We define the waiting time as a time interval during which the normalize…
