基于JAVA建立树形结构的算法优化

树形结构在程序设计过程具有非常重要的作用,但树形结构的构建相对比较复杂。通过研究设计并实现一种从普通Java对象中建立树形结构的优化算法。     

A Method for Time-Series Location Data Publication Based on Differential Privacy

In the age of information sharing, logistics information sharing also faces the risk of privacy leakage. In regard to the privacy leakage of time-series location information in the field of logistics, this paper proposes a method based on differential privacy for time-series location data publication. Firstly, it constructs public region of interest(PROI) related to time by using clustering optimal algorithm. And it adopts the method of the centroid point to ensure the public interest point(PIP) representing the location of the public interest zone. Secondly, according to the PIP, we can construct location search tree(LST) that is a commonly used index structure of spatial data, in order to ensure the inherent relation among location data. Thirdly, we add Laplace noise to the node of LST, which means fewer times to add Laplace noise on the original data set and ensures the data availability. Finally, experiments show that this method not only ensures the security of sequential location data publishing, but also has better data availability than the general differential privacy method, which achieves a good balance between the security and availability of data.

Science Letters： A synthetic Toll-like receptor 2 ligand decreases allergic immune responses in a mouse rhinitis model sensitized to mite allergen

It has been proposed that activation of Toll-like receptors （TLRs） plays crucial roles in the polarization of adaptive immune responses. A synthetic Toll-like receptor 2 （TLR2） ligand, Pam3CSK4, has been reported to modulate the balance of Th1/Th2 responses. We evaluated the modulation effect of Pam3CSK4 on allergic immune response in a mouse rhinitis model sensitized to house dust mite allergen （HDM）. Mice were sensitized and challenged with Dermatophagoidesfarinae allergen （Der f）, and then the allergic mice were treated by Pam3CSK4. Nasal allergic symptoms and eosinophils were scored. Der f-specific cytokine responses were examined in the splenocytes and bronchoalveolar lavage fluid （BALF）. Serum level of total IgE was also detected. After establishing a mouse allergic rhinitis model with HDM, we have showed that Pam3CSK4 treatment not only ameliorated the nasal allergic symptoms remarkably but also decreased the eosinophils and total inflammation cells in BALF significantly. Analysis of cytokine profile found that IFN-7 released from either BALF or stimulated splenocytes increased markedly in Pam3CSK4-treated mice, while IL-13 decreased significantly. Moreover, serum level of total IgE was significantly lower in Pam3CSK4-treated mice than in the untreated. Thus, in an allergic rhinitis mouse model developed with HDM, Pam3CSK4 was shown to exhibit an antiallergic effect, indicating its potential application in allergic diseases.     

创新思维在成功决策中的地位和作用

创新思维在成功决策中的地位和作用在于:它倡导相兼相容的系统观,主张打破基本假设的惯性,追求战胜自我的最高境界,强调领导者或管理者的素质,要求领导者或管理者永远保持一种创造精神.要成为成功决策的高手,一方面要防止决策中常犯的错误,另一方面要不断提高决策的水平和能力.     

试论贾岛古体诗对孟郊诗歌的继承

孟郊和贾岛是唐代两位著名的苦吟诗人，两人分别在五古和五律方面有着独特的建树，但贾岛的古体诗明显受到了孟郊诗歌的影响。具体来说，贾岛的古体诗只用五言的形式，呈现出奇而硬的风格，有着乐府化的倾向，这三方面都可以看出与孟郊诗歌的渊源关系。     

The Geometric Construction of WZW Effective Action in Noncommutative Manifold

By constructing close-one-cochain density Ω^12n in the gauge group space we get the Wess-Zumino-Witten (WZW) effective Lagrangian on high-dimensional noncommutative space.Especially consistent anomalies derived from this WZW effective action in noncommutative four-dimensional space coincide with those obtained by L.Bonora etc.(het-th/0002210).     

论东莞城市化过程中农民的就业出路

农村城市过程中必须出现农民的失业问题，东莞也不例外，本文从东莞农民面临的失业问题出发，认为产生这一问题的直接原因是耕地迅速减少，外地来工的竞争，本地农民文化低下，以及耕地集中使用等，为了解决农民的就业问题，本文认为应鼓励农民从专业化，商品化的农业生产，大力发展农村非的农产业，大力发展农村文化教育事业，建立多层次，多功能，多形式的劳动力市场。     

形与神——中国医学的“魂”论

分析中国古代特别是中国传统医学中关于“神”即人“魂”的学说．作者论证，中国人所认为的人“魂”与欧洲的传统有很大的不同，是以物质性作为其特征的，或者说“魂”并不是一个非物质的东西．     

ICP-AES测定饮用水源中的Cu、Mn、Pb、Cd、Zn

用ICP－AES法同时测定饮用水源中的Cu、Mn、Pb、Cd、Zn等重金属元素，具有基体效应小、测量范围宽等优点。检出限为0．2－4．0μg/L，回收率为91．5％－103．9％，相对标准偏差为0．29％－1．5％，测定密码样与实际样品，结果令人满意。
