    Goal−directed Weakening of Abstract Interpretation Results

    No full text
    One proposal for automatic construction of proofs about programs is to combine Hoare logic and abstract interpretation. Constructing proofs is in Hoare logic. Discovering programs' invariants is done by abstract interpreters. One problem of this approach is that abstract interpreters often compute invariants that are not needed for the proof goal. The reason is that the abstract interpreter does not know what the proof goal is, so it simply tries to find as strong invariants as possible. These unnecessary invariants increase the size of the constructed proofs. Unless the proof-construction phase is notified which invariants are not needed, it blindly proves all the computed invariants. In this article, we present a framework for designing algorithms, called abstract-value slicers, that slice out unnecessary invariants from the results of forward abstract interpretation. The framework provides a generic abstract-value slicer that can be instantiated into a slicer for a particular abstract interpretation. Such an instantiated abstract-value slicer works as a postprocessor to an abstract interpretation in the whole proof-construction process, and notifies to the next proof-construction phase which invariants it does not have to prove. Using the framework, we designed an abstract-value slicer for an existing relational analysis and applied it on programs. In this experiment, the slicer identified 62%-81% of the computed invariants as unnecessary, and resulted in 52%-84% reduction in the size of constructed proofs.S. Seo and T.

    In this thesis, I study how food resources and dietary conditions were determined by social and economic status during the Han period in China, B.C. 206~A.D.220. Even though earlier scholars have published research concerning the Chinese food culture of this period, these studies were limited in that they only illustrated the dietary culture of the upper class or the available food resources in one geographic area. Also, without any persuasive data, it has been assumed by these earlier scholars that there were big differences in food resources and food consumption between the upper and lower classes. In this thesis, for comparison among the classes, I divide the social and economic classes into five stratified groups: nobles, officials, peasants, soldiers and convicts. After a brief introduction of the nature of each social class, I examine the food resources and nutritional condition of each group using information such as the wealth and income of each group, the market price of food resources, the agricultural products of peasants, and the amount of food distribution to soldiers and convicts. I found these data from archaeological remains, received historical records and pictorial data, and excavated texts. This research shows a broader view of Chinese dietary condition focusing not only on the variety of food resources of nobles, but also on the different food accessibilities among the officials, and the food deficiencies of peasants. It also deals with the situations of food supply for soldiers and convicts in an effort to reveal the true dietary consumption and nutritional conditions for all Chinese. This research proves that the various classes during the Han period in China had different food resources and dietary conditions

    Uprooted: A conversation with Artist Yang Yi

    No full text
    Chinese photo artist Yang Yi was born in a small town by the Yangtze River. His Uprooted series made in 2007 foreshadowed the inundation of his hometown due to the construction of Three Gorges Project and the loss and preservation of memories. For Yang Yi, the Three Gorges Project not only inundated the physical space, but affected all of life and disrupted a long history and tradition of his hometown. Yang Yi has participated in many solo and group exhibitions in China and abroad. In 2010, he was selected to be one of that year’s PDN 30 New and Emerging Photographers to Watch

    The immune-modulatory effects of a mixed herbal formula on dendritic cells and CD4(+) T lymphocytes in the treatment of dust mite allergy asthma and perennial allergic rhinitis

    Objective: Asthma and allergic rhinitis are chronic inflammatory diseases of the conducting nasal airway. Traditional Chinese medicine has long been used for supplemental therapy of allergic diseases, especially asthma and allergic rhinitis. We previously reported the effects of a mixed herbal formula in patients with allergic rhinitis. However, the immune-modulatory mechanism underlying the effects of herbal medicine for the treatment of allergic diseases remains unclear. Methods: We investigated the physiologic changes in dendritic cell (DC) and CD4(+) T cell activity in patients with asthma and allergic rhinitis who were treated with a mixed herbal formula composed of Xin-yi-san+Xiao-qing-long-tang+Xiang-sha-liu- jun-zi-tang. Specifically, we set up in vitro autologous or heterologous co-culture experiments between DCs and CD4(+) T cells, and used flow cytometry and ELISA to analyze the expression of surface molecules on DCs and the release of cytokines by CD4(+) T cells. Results: Expression of HLA-DR on DCs was suppressed following treatment with the mixed herbal formula. Surface expression of CD40, CD54 and CD86 on DCs was also attenuated after treatment. In autologous co-cultures, CD4(+) T cells increased their IL-10 production while decreasing TNF- production. In heterologous co-cultures, IL-10 secretion by T cells was enhanced, while IL-12, IL-4, IL-5 and TNF- secretion were reduced. Conclusion: Our mixed herbal formula attenuated the allergic reaction by modifying the physiologic function of the DC-CD4(+) T cell interaction. Further investigations are necessary to understand the mechanism of immune modification mediated by the mixed herbal formula
