conclusions the role of exercise is greater in the retention than the acquisition phase for recalling past experiences. background stress induced by sleep deprivation can cause degradation of learning in the acquisition phase, and low-intensity exercise can prevent the negative effects of stress. results the results showed that, after seven days of aerobic exercise on a treadmill, the experimen...

nowadays, use of e-learning is one of the opportunities that information technology has provided for the teaching. since the method of training has become an industry so the concepts of value and value creation in the value chain need to be reviewed and updated based on e-learning system components. in this paper, with the aim of offering optimized value chain in the comparative study of tradit...

First language acquisition requires relatively little effort compared to foreign language acquisition and happens more naturally through informal learning. Informal exposure can also benefit foreign language learning, although evidence for this has been limited to speech perception and production. An important question is whether informal exposure to spoken foreign language also leads to vocabu...

conclusions the results of this study indicated that there was willingness and a need to share knowledge and skills with other undergraduates as a way of resolving clinical problems at tums. thus, implementing shared learning programs could promote the quality of provided patient care via increasing the teamwork and communication skills of the undergraduate students. background current evidence...

We determine the optimal performance of learning the orientation of the symmetry axis of a set of P 5aN points that are uniformly distributed in all the directions but one on the N-dimensional space. The components along the symmetry breaking direction, of unitary vector B, are sampled from a mixture of two Gaussians of variable separation and width. The typical optimal performance is measured ...
