This paper studies a scheduling game on uniform machines with social cost of maximizing the minimum machine load. For the game with two machines, we present the (Strong) Price of Stability and (Strong) Price of Anarchy as a function of s, the ratio of the speeds of the two machines. These bounds are all tight for any value of s, thus the problem of(More)
Cardiac tissue engineering using biomaterials with or without combination of stem cell therapy offers a new option for repairing infarcted heart. However, the bioactivity of biomaterials remains to be optimized because currently available biomaterials do not mimic the biochemical components as well as the structural properties of native myocardial(More)
Over the past several decades, rocky desertification has led to severe ecological problems in karst areas in South China. After a rocky desertification treatment project was completed, the vegetation coverage changed greatly and, consequently, increased the ecology water consumption (approximately equal to the actual evapotranspiration) of the regional(More)
