	3	Stochastic leaderefollower DEA models for two-stage systems显示文摘Data envelopment analysis(DEA)is a non-parametric approach for measuring the relative efficiencies of peer decision making units(DMUs).In recent years,it has been widely used to evaluate two-stage systems under different organization mechanisms.This study modifies the conventional leaderefollower DEA models for two-stage systems by considering the uncertainty of data.The dual deterministic linear models are first constructed from the stochastic CCR models under the assumption that all components of inputs,outputs,and intermediate products are related only with some basic stochastic factors,which follow continuous and symmetric distributions with nonnegative compact supports.The stochastic leaderefollower DEA models are then developed for measuring the efficiencies of the two stages.The stochastic efficiency of the whole system can be uniquely decomposed into the product of the efficiencies of the two stages.Relationships between stochastic efficiencies from stochastic CCR and stochastic leaderefollower DEA models are also discussed.An example of the commercial banks in China is considered using the proposed models under different risk levels.

	4	Distinct stem/progenitor cells proliferate to regenerate the trachea,intrapulmonary airways and alveoli in COVID-19 patients显示文摘Dear Editor,The global pandemic COVID-19 caused by SARS-CoV-2 virus has infected over 6.5 million individuals and claimed over 350,000 lives worldwide within six months.The respiratory epithelial cells covering the airways and alveoli are the major targets of the virus.Moreover,damage to the epithelium can be exacerbated by mechanical ventilation.It is expected that many of the infected individuals that survived the acute phase will develop pulmonary diseases(e.g.fibrosis)if the epithelium fails to regenerate properly.
