    • The present invention refers to a method and process for the encapsulation of highly water soluble materials in the further termed "Reverse Phase Layer-by-Layer (RP-LbL) Encapsulation". State of the art polyelectrolyte self assembly Layer-by-Layer coating or encapsulation methods are only applicable to non water soluble materials. The current invention provide a novel method to extend the material spectrum to highly water soluble materials by using non-ionized polyelectrolytes in an organic phase (Reverse Phase) instead of polyelectrolyte salts in an aqueous environment of the common art. Reverse Phase LbL is applicable to encapsulate highly water soluble substances, such as proteins, sugars, ascorbic acid, fragrants, inorganic salts, amino acids and vitamins, which could not be encapsulated by the current LbL technology.
    • 本发明涉及一种用于将高水溶性材料封装在进一步称为“反相层析(RP-LbL)封装”中的方法和方法。 现有技术的聚电解质自组装层叠涂层或包封方法仅适用于非水溶性材料。 本发明提供了一种通过在有机相(反相)中使用非电离聚电解质而不是普通技术的水性环境中的聚电解质盐将材料谱扩展到高度水溶性材料的新方法。 反相LbL适用于包封高度水溶性物质,如蛋白质,糖类,抗坏血酸,香料,无机盐,氨基酸和维生素,不能被目前的LbL技术所包封。

    • A method and apparatus for implementation in a database management system transforms high-dimensional data points to a single-dimensional space so that single-dimensional values can be used as representative index keys for high-dimensional data points and a single-dimensional index structure can be employed to index the transformed values. Upon achieving transformed values, known single-dimensional indexing structures can be employed. To achieve transformation from high-dimensions to a single-dimension, attribute values of a data item, each representing a different dimension, are mapped into a range and an integer value is assigned to each dimension. Either the minimum or maximum dimension value for the multi-dimensional data item is selected, and the minimum or maximum dimensional value is added to the integer value. As a result of this transformation, data points are mapped over a range in a single dimension and associated single-dimension values are used as a representative index key for subsequent search queries.
    • 用于在数据库管理系统中实现的方法和装置将高维数据点转换为单维空间,使得可以将单维值用作高维数据点的代表性索引关键字,并且一维索引结构可以 被用来索引变换后的值。 在实现变换值时,可以采用已知的单维索引结构。 为了实现从大维到单维的转换,将表示不同维度的数据项的属性值映射到一个范围内,并将整数值分配给每个维度。 选择多维数据项的最小或最大尺寸值,并将最小或最大尺寸值添加到整数值。 作为该变换的结果,数据点在单个维度的范围内映射,并且相关联的单维值被用作后续搜索查询的代表索引关键字。
