中日丝绸业的逆转与东海丝路的兴衰

中日丝绸交流长达两千余年,一直是东海丝路上的主角。日本通过持续不断地学习中国先进的蚕丝和丝织技术,为本国丝绸业的迅速发展乃至后来居上打下了坚实的基础。尤其从15世纪起,日本利用明朝海禁导致国内市场扩大而放手发展丝织业,又因进口生丝造成白银大量外流而努力发展蚕丝业,从而建立起"养蚕——缫丝——丝织"完整的丝绸生产体系,彻底摆脱了对中国丝织品和生丝原料的依赖,最终使东海丝路因丝绸贸易日渐萧条而不可避免地走向了衰落。保持科技优势以掌握国际贸易主导权、通过双向交流以确保国际贸易航路长盛不衰,应是我们在重建海上丝绸之路时予以汲取的宝贵历史经验。

An evaluation framework for cross-lingual link discovery

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9.     

Generalized matrix projective synchronization of general colored networks with different-dimensional node dynamics

This paper investigates the generalized matrix projective synchronization problem of general colored networks with different-dimensional node dynamics. A general colored network consists of colored nodes and edges, where the dimensions of colored node dynamics can be different in addition to the difference of the inner coupling matrices between any pair of nodes. For synchronizing a colored network onto a desired orbit with respect to the given matrices, open-plus-closed-loop controllers are designed. The closed-loop controllers are chosen as adaptive feedback and intermittent controllers, respectively. Based on the Lyapunov stability theory and mathematical induction, corresponding synchronization criteria are derived. Noticeably, many existing synchronization settings can be regarded as special cases of the present synchronization framework. Numerical simulations are provided to verify the theoretical results.
