In this paper, we proposed a novel efficient method of analyzing the ergodic channel capacity of the cooperative amplify-and-forward (CAF) relay system. This is accomplished by employing a very tight approximate moment generating function (MGF) of end-to-end signal-to-noise ratio of 2-hop multi-relay system, which is In this paper, we proposed a novel efficient method of analyzing the ergodic c...

This study explores the effect of collaborative writing (CW) and peer feedback (PF) practices on subsequent individual assignments. Two groups university students in a Spanish as foreign language course experienced both CW PF (Group 1 then PF; Group 2 CW), pre posttests were analyzed for syntactic complexity, lexical diversity, accuracy, fluency, well overall quality using an analytic scale. Re...

This study reports on an experiment in which a group of 14 American learners of Spanish as a foreign language performed two monologic production tasks with and without time for planning. Several hypotheses were tested concerning language complexity, grammatical accuracy, lexical complexity, and degree of fluency. As predicted, it was found that learners produced more complex, but not more accur...

This study investigated the long-term effectiveness of explicit versus implicit instruction in a classroom setting. The participants were 114 Dutch secondary school students learning English as an L2; control group received and intervention meaning-based context for two academic years. Instructional effects measured via timed writing task. products groups compared terms holistic quality, comple...

This meta-analysis is an investigation into the impressibility of two dimensions of the speaking skill, namely accuracy and fluency, in relation to the experimented treatments among Iranian EFL undergraduates. Having surveyed a collected bank of 74 research reports, the relationships among the variables in the 14 included studies were examined. More specifically, the analysis involved a statist...

Introduction Regeneration therapy using adipose-derived stem cells (ADSC) has been proposed in the treatment of skin aging. Myofibroblast plays a relevant role in the organization of the extracellular matrix of the damaged skin. A natural extract was derived from the eggs of the mollusk Cryptomphalus aspersa (e-CAF) that seems to play a role on skin repair. We have investigated the potential ef...
