TESTING THE PREDICTABILITY OF CONSUMPTION GROWTH: EVIDENCE FROM CHINA
Liping Gao,HYEONGWOO KIM 중앙대학교 경제연구소 2016 Journal of Economic Development Vol.41 No.3
Using time series macroeconomic data, Chow (1985, 2010, 2011) reported indirect empirical evidence that implies the validity of the permanent income hypothesis in China. We revisit this issue by evaluating direct measures of the predictability of consumption growth in China during the post-economic reform regime (1978-2009). We also implement and report similar analysis for the postwar U.S. data for comparison. Our in-sample analysis provides strong evidence against the PIH for both countries. Out-of-sample forecast exercises show that consumption changes are highly predictable, which sharply contrasts the implications of empirical findings by Chow (1985, 2010, 2011).

In real-time collaborative graphical editing systems, Object-based Group/Ungroup operations are frequently accessible and practically useful. However, the existing research on these operations of the graphical editing is rare and defective. In this paper, based on Multi-Version strategy and Address Space Transformation method, a new MVSDR algorithm, which is not only applied to simple operations (such as Create, Delete, ChangeATT, etc.), but also suitable for Group/Ungroup ones, is proposed to solve the consistency maintenance problem. The proposed algorithm abandons previous attempts to divide conflict operations into Real-Conflict operations and Resolvable-Conflict ones and to deal with them separately, thus making the algorithm more simple and effective. In addition, an example analysis is also given in this paper to prove the algorithm’s correctness and effectiveness.
High Efficient Consistency Maintenance Strategy of Real-time String Text Editing Systems
Liping Gao,Wenfeng Tang 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.10
The idea of address space transformation provides a new way for concurrency control. During concurrent processing, it retraces the document status back to the state when the operations are generated to maintain consistency. However the previous concurrency processes strategy is based on single characters, the transmission cost during processing is too high, especially when the network is unstable. Due to this problem, this paper presents a consistency maintenance strategy based on string editing operations, and proposes the string splitting mechanism combined with the idea of the address space transformation in order to maintain consistency.

Background WS24-3A is a newly bred non-heading Chinese cabbage genic male-sterile line, in which sterility is controlled by a recessive gene, designated as Bra2ms. WS24-3A has been used for hybrid breeding. Objective To reveal the underlying molecular mechanisms responsible for the sterility of WS24-3A. Methods Cytological observation of the process of sterile/fertile anther development was performed to determine the tissue and stage in which sterility occurs. Phenotyping and transcriptomic analyses were performed to identify differentially expressed genes (DEGs) between sterile and fertile flower buds at different stages. Results Cytological analysis revealed no tetrads at stage 7 or at later stages of anther development, and the degradation of callose was delayed. Abnormal meiocytes were surrounded by sustaining callose that degenerated gradually in WS24-3A. Comparative transcript profiling identified 3282 DEGs during three anther developmental stages, namely, pre-meiotic anther, meiotic anther, and anthers with single-celled pollen stage. The difference in DEG percentage between up-regulated and down-regulated at meiotic anther stage was obviously larger than at the other two stages; further, most DEGs are important for male meiosis, callose synthesis and dissolution, and tapetum development. Ten DEGs were found to be involved in anther and pollen development, which were analyzed by quantitative PCR. Conclusion Bra2ms affected gene expression in meiocytes and associated with callose synthesis, degradation and tapetum development. Our results provide clues to elucidate the molecular mechanism of genic male sterility in non-heading Chinese cabbage.
Frequency and Length Adjustment of A PEFP Low-Beta Dumbbell
Changyi, Gao,An, Sun,Liping, Zhang,Yazhe, Tang,Yingmin, Li,Kim, Han-Sung,Cho, Yong-Sub The Korean Society of Superconductivity and Cryoge 2008 한국초전도저온공학회논문지 Vol.10 No.2
Superconducting RF cavities are being considered for accelerating a proton beam at 700 MHz in the linac of the Proton Engineering Frontier Project (PEFP) and its post-project. Dumbbell fabrication is a mid-process for manufacturing an elliptical superconducting RF cavity. During the dumbbell fabrication, control of the dumbbell length and the $TM010\;{\pi}$ mode frequencies is necessary to build up a desired cavity. A new formula with a perturbation measurement method is used to measure and calculate the frequencies of the individual half-cells of a PEFP low-beta dumbbell, and to tune the frequency and length of the half-cells. In this article, the tuning method and results of the PEFP low-beta dumbbells have been presented.

With the real-time group editing system, a group of users can view and edit the shared document by communication networks anytime and anywhere. Under the circumstance, it is surely inevitable that many operations from different users are going to conflict. Thus, two issues, the conflict resolution and the consistency maintenance, are the most important for designing and completing the system. In the past, the address space transformation algorithm, invented from the research about the real-time text editing system, could maintain consistency among more sites. The Multi Version conflict resolution approach could preserve users’ intentions but not all when conflicts occur. This paper proposes a new solution of conflict resolution, named Intention Combination Conflict Resolution strategy with the document model of AST based on the idea of Multi Version approach. This solution can not only preserve all users’ editing consistency by intention combination, but also keep all versions of operational objects including conflict operations’ combination effects. In addition, the effectiveness of related algorithms is analyzed, and the availability of the strategy is described by a case and proved by our experiment.
