background: the internet is a phenomena that changes human, specially the younger generation’s, life in the 21st century. online communication is a common way of interacting among adolescents who experience feelings of social anxiety. the aim of this study was to investigate the relationship between social anxiety and online communication in adolescents. methods: three hundred and thirty studen...

In this article, we investigate a promising transmission approach for green communication networks. By combining the appealing single-cycle modulation technique with traditional pulse modulation found on the underlay communication philosophy, the presented ultra-spectra communication system can improve the energy efficiency significantly. In transceiver, the emission signal contains two parts, ...

We present a subtle idea to economically improve message-unilaterally-transmitted quantum secure direct communication (QSDC) protocols to realize two-way secure direct communication. Suppose Alice and Bob securely share a secret key. When the message sender, say, Alice, wants to send her secret messages to Bob, she can first use the secret key to encrypt her secret messages, then she publicly s...

As against the conventional send/receive model, the one-way communication is a new paradigm which decouples message transmission and synchronization. This opens up new opportunities not only to further optimize communication but also to minimize synchronization costs. In this paper, we present a generalized technique which makes use of global dataflow framework to optimize communication and syn...
