Thermal expansion properties of hydrogenated graphene are investigated by performing the first-principles calculations. We find that both fully hydrogenated graphene (graphane) and half hydrogenated graphene (graphone) exhibit negative thermal expansion properties at low temperatures. Their...

The mean residual life provides the remaining life expectancy of a subject who has survived to a certain time-point. When covariates are present, regression models are needed to study the association between the mean residual life function and potential regression covariates. In this paper, we...
