Y.-M. Wang, Y.-X. Lan / Mathematical and Computer Modelling 54 (2011) 2760–2771 2761 TheDEA-basedMPI has proven to be a very useful tool formeasuring the productivity changes of DMUs in the past several decades. For instance, Färe et al. [13] applied it to analyze the productivity growth in industrialized countries. Grifell-Tatjé and Lovell [14] used it tomeasure the effect of deregulation on S...

Chronic cerebral hypoperfusion, a sustained modest reduction in cerebral blood flow, is associated with damage tomyelinated axons and cognitive decline with ageing. Oligodendrocytes (the myelin producing cells) and their precursor cells(OPCs) may be vulnerable to the effects of hypoperfusion and in some forms of injury OPCs have the potential to respondand repair damage by incre...
