Working memory (WM), which includes short-term memory and cognitive control, has been found to be closely related to a wide range of high-level cognitive abilities and academic achievement. Prior studies showed children with attention-deficit/hyperactivity disorder improved their WM and fluid intelligence through computerized cognitive training (CCT) in a clinical setting.
This research examined whether regular middle-school students would significantly improve their WM through CCT on WM; and if so, whether increase in WM would lead to improved fluid intelligence and science achievement. Two...

Chilldown process is a complicated process involves unsteady two-phase heat and mass transfer and initiates the cryogenic fluids transport. To advance the understanding of this process, both experimental and modeling investigations have been carried. The chilldown process can be generally divided into three regions which are associated with different flow regimes and heat transfer mechanisms. Under low flow conditions, the two-phase flow during chilldown is dispersed. The statistic feature of the liquid filaments is studied and a model, in which the heat transfer at the bottom is considered...
