This brief presents the novel PHY layer technique, attachment transmission, which provides an extra control panel with minimum overhead. In addition to describing the basic mechanisms of this technique, this brief also illustrates the challenges, the theoretical model, implementation and numerous applications of attachment transmission. Extensive experiments demonstrate that attachment transmission is capable of exploiting and utilizing channel redundancy to deliver control information and thus it can provide significant support to numerous higher layer applications. The authors also address...

This book examines how educational change has progressed in three contrasting areas spread across China since 1990, exploring key issues concerning rural education in poor, rich and minority areas. Of the three areas covered in this book, the first is a rich one near Beijing; the second is in the northwest in Shanxi on the Loess plateau; and the third is in Sichuan on the high plateau leading to Tibet.
