Macroblock-level decoding and deblocking method and its pipeline implementation in H.264 decoder SOC design

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第1期8卷 36-41页

作者： WANG Shu-hui LIN Tao LIN zheng-hui Department of Electronic Engineering Shanghai Jiao Tong University Shanghai 200030 China

This paper presents a macroblock-level (MB-level) decoding and deblocking method for supporting the flexible macroblock ordering (FMO) and arbitrary slice ordering (ASO) bit streams in H.264 decoder and its SOC/ASIC implementation. By searching the slice containing the current macroblock in the bit stream and switching slices correctly, MBs can be decoded in the raster scan order, while the decoding process can immediately begin as long as the slice containing the current MB is available. This architectural modification enables the MB-level decoding and deblocking 3-stage pipeline, and saves about 20% of SDRAM bandwidth. Implementation results showed that the design achieves real-time decoding of 1080HD (1920×1088@30 fps) at a system clock of 166 MHz.

Chinese Physics C 2013年第8期37卷 64-68页

作者： Mi zheng-hui mizh@*** Institute of High Energy Physics Chinese Academy of Sciences Beijing 100049 China

The tuning system plays a very important role when a superconducting cavity is in operation. It cooperates with other control loops to adjust the cavity frequency with high precision, reduce the reflection power, guarantee the stability of beam, and ensure the safety of the superconducting cavity. This paper focuses mainly on the tuning system working principle, the working state and problems that Beijing Electron Positron Collider （BEPC ｜I ） has encountered during operation.

Petroleum systems in the Damintun Depression, Liaohe Oilfield

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第11期8卷 1864-1871页

作者： zheng Li-hui XING Yu-zhong School of Energy Resources China University of Geosciences Beijing 100083 China International Research Center Beijing China National Petroleum Corporation （CNPC） Beijing 100083 China

There are two different types of oils—high-wax oil and normal oil—found in the Damintun Depression of Liaohe Oilfield after several years of exploration and development, but their distributions and origins had confused the explorers in the oilfield. The introduction of petroleum-system concept shifts the view of geoscientists from geology and geophysics to oil, gas and their related source rocks. After detailed study, two petroleum systems have been identified in the Damintun Depression: (1) the ES42-Ar buried hill petroleum system (called the high-wax oil petroleum system) and (2) the ES41+ES34-ES4 and ES3 petroleum system (called the normal oil petroleum system). Based on the detailed analysis of the basic components, and all the geological processes required to create these elements of the two petroleum systems, it is put forward that targets for future exploration should include the area near Dongshenpu-Xinglongpu and the area near the Anfutun Sag. This provides scientific basis and has theoretical and practical meaning for the exploration and development.

Repassivation behavior of alloy 690TT in simulated primary water at different temperatures

Journal of Materials Science & Technology 2021年第9期68卷 227-235页

The repassivation behavior of Alloy 690 T T in simulated primary water at different temperatures was investigated by the rapid scratching electrode technique together with electrochemical *** results showed that the repassivation process had three stages: the initial stage conformed to the place exchange model, the final stage conformed to the high field ion conduction model and in between there was a transition stage. At the initial stage, when the repassivation process of alloys was controlled by the place exchange model, anodic dissolution of substrate was dominated;after the film coverage rate was more than 0.99, the repassivation process of alloys was controlled by high field ion conduction model. Increasing the temperature resulted in a reduction of the repassivation rate and protectiveness of the passive film. The correlations among several mechanisms describing the repassivation behavior of alloys were discussed.

Identification of MicroRNAs in Wild Soybean (Glycine soja)

引用

Journal of Integrative Plant Biology 2009年第12期51卷 1071-1079页

作者： Rui Chen zheng Hu hui Zhang The National Key Facilities for Crop Genetic Resources and Improvement Institute of Crop Sciences Chinese Academy of Agricultural Sciences Beijing 100081 China

MicroRNAs （miRNAs） play important roles in post-transcriptional gene silencing by directing target mRNA cleavage or translational inhibition. Currently, hundreds of miRNAs have been identified in plants, but no report has been published of wild soybean （Glycine soja Sieb）. We constructed a small-RNA library consisting of 2 880 sequences with high quality, in which 1 347 were 19-24 nt in length. By utilizing the miRNA, Rfam and domesticated soybean expressed sequence tag database, we have analyzed and predicted the secondary structure of these small RNAs. As a result, t5 conserved miRNA candidates belonging to eight different families and nine novel miRNA candidates comprising eight families were identified in wild soybean seedlings. All these miRNA candidates were validated by northern blot and the novel candidates expressed in a tissue-specific manner. Furthermore, putative target genes were predicted for novel miRNA candidates and two of them were verified by 5＇-rapid amplification of cDNA ends experiments. These results provided useful information for miRNA research in wild soybean and plants.
