Buffer-aided network coding (NC) has been proposed as an effective method to improve retransmission efficiency. In this way, the correctly received undecodable NC combined retransmission packets are waited in the buffer for a future network decoding opportunity rather than delete. However, existing buffer-aided approaches fail to consider the buffer status(More)
Multimedia streaming applications have stringent Quality-of-Service (QoS) requirements. Typically, each packet is associated with packet delivery deadline. We are interested in designing feedback-based adaptive network coding schemes with the aim of minimizing decoding delay and video distortion in wireless broadcasting networks over the packet-erasure(More)
A powerful reagent, P[NCH(3)(OCH(3))](3) (3), for conversion of carboxylic acids directly to Weinreb amides was developed. In most cases the yields of the corresponding Weinreb amides were above 90% when P[NCH(3)(OCH(3))](3) was heated with aromatic and aliphatic carboxylic acids in toluene. The sterically hindered carboxylic acids can also give the(More)
