SUMMARY Triggered by the explosion of mobile traffic, 5G cellular network requires evolution to increase the system rate 1000 times higher than the current systems in 10 years. Motivated by this common problem, this paper studies to integrate mm-wave access into current cellular networks as multi-band heterogeneous networks to exploit the ultra-wideband(More)
To examine the factors underlying children's categorization modes (holistic vs. analytic) and ease of classification learning, 5-6 year-olds were given a classification task of schematic faces with two values in each of five dimensions. The tasks varied on the similarity between sample and learning exemplars (high vs. low) and the number of categories to be(More)
