It is well known that orthogonal coding can be used to approach the Shannon capacity of the power-constrained AWGN channel without a bandwidth constraint. This correspondence describes a semi-orthogonal variation of pulse position modulation that is sequential in nature — bits can be “streamed across” without having to buffer up blocks of bits at the transmitter. ML decoding results in an expon...

The broadcast throughput in a network is defined as the average number of messages that can be transmitted per unit time from a given source to all other nodes when time goes to infinity. Classical broadcast algorithms treat messages as atomic tokens and route them from the source to the receivers by making intermediate nodes store and forward messages. The more recent network coding approach, ...

Rate control plays an important role in high quality video coding. In this paper, a rate control algorithm based on video characteristics is proposed. Firstly, we put forward a novel bit allocation algorithm for intra frame by analyzing the relationship among the image characteristic, bit per pixel and quantization step. The image gradient is used as image characteristic. In frame layer, differ...

—High Efficiency Video Coding (HEVC) exploits quad-tree structured Coding Unit (CU) to improve compression efficiency. It saves about 50% coding bits as compared with the former standard H.264/AVC high profile. However, the computational complexity is dramatically increased for more partition blocks and coding modes supported in HEVC. In this paper, a fast CU decision algorithm is proposed to ...

Melioidosis is an infectious disease caused by the pathogenic bacterium Burkholderia pseudomallei. Whole-genome sequencing revealed that the B. pseudomallei genome includes 5855 coding DNA sequences (CDSs), of which ∼25% encode hypothetical proteins. A pathogen-associated hypothetical protein, BPSL1038, was overexpressed in Escherichia coli, purified and crystallized using vapour-diffusion meth...

The emergence of the new generation video coding standard, Versatile Video Coding (VVC), has brought along novel features rendering standard more efficient and flexible than its predecessors. Aside from compression 8 k or higher camera-captured content, VVC also supports a wide range applications, including computer-generated high dynamic (HDR) multilayer multi-view coding, region extraction, a...
