摘要： 数字对象标识符（digitalobjeetidentifier，DOI）是对包括互联网信息在内的数字信息进行标识的一种工具。在传统的出版物中，书刊、磁带、光盘都有国际标准编号（ISBN、ISSN、ISCN）及其条形码，作为出版物的惟一标识。这些标识使出版物得到有效的管理，便于读者查找和利用。而网上的文档一旦变更了网址（URL）便无从追索。数字信息标注DOI如同出版物的条形码，是一个永久和惟一的标识号，随着时间推移，数字对象的某些有关信息可能会有变化（包括存储的物理位置），而DOI可让使用者直接由此链接到出版商的数据库、文献、摘要甚至是全文，识别码可以直接指引到出版物的本身，使国内外各种来源、不同物理地址的各种类型的学术信息实现互链互通。DOI是一个可供全球期刊快速链接的管理系统，整个系统由国际DOI基金会（IDF）进行全球分布式管理。

关键词： Potts model  

摘要： A method of estimation of the quality of data identification by a parametric perceptron is presented. The method allows one to combine the parametric perceptrons into a committee. It is shown by the example of the Potts perceptrons that the storage capacity of the committee grows linearly with the increase of the number of perceptrons forming the committee. The combination of perceptrons into a committee is useful when given task parameters (image dimension and chromaticity, the number of patterns, distortion level, identification reliability) one perceptron is unable to solve the identification task. The method can be applied in q-nary or binary pattern identification task. © Allerton Press, Inc., 2009.

摘要： Background. Adhesive capsulitis often is difficult to diagnose in its early stage and to differentiate from other commonly seen shoulder disorders with the potential to cause pain and limited range of movement. Objectives. The purpose of this study was to establish consensus among a group of experts regarding the clinical identifiers for the first or early stage of primary (idiopathic) adhesive capsulitis. Design. A correspondence-based Delphi technique was used in this study. Methods. Three sequential questionnaires, each building on the results of the previous round, were used to establish consensus. Results. A total of 70 experts from Australia and New Zealand involved in the diagnosis and treatment of adhesive capsulitis completed the 3 rounds of questionnaires. Following round 3, descriptive statistics were used to screen the data into a meaningful Subset. Cronbach alpha and factor analysis then were used to determine agreement among the experts. Consensus was achieved on 8 clinical identifiers. These identifiers clustered into 2 discrete domains of pain and movement. For pain, the clinical identifiers were a strong component of night pain, pain with rapid or,unguarded movement, discomfort lying on the affected shoulder, and pain easily aggravated by movement. For movement, the clinical identifiers included a global loss of active and passive range of movement, with pain at the end-range in all directions. Onset of the disorder was at greater than 35 years of age. Conclusions. This is the first study to use the Delphi technique to establish clinical identifiers indicative of the early stage of primary (idiopathic) adhesive capsulitis. Although limited in differential diagnostic ability, these identifiers may assist the clinician in recognizing early-stage adhesive capsulitis and may inform management, as well as facilitate future research.

摘要： This paper proposes a robust adaptive fuzzy PID control scheme augmented with a supervisory controller for unknown systems. In this scheme. a generalized fuzzy model is used to describe a class of unknown systems. The control strategy allows each part of the control law. i.e., a supervisory controller, a compensator, and an adaptive fuzzy PID controller, to be designed incrementally according to different guidelines. The supervisory controller in the outer loop aims at enhancing system robustness in the face of extra disturbances, variation in system parameters, and parameter drift in the adaptation law. Furthermore, an H-infinity control design method using the fuzzy Lyapunov function is presented for the design of the initial control gains that guarantees transient performance at the start of closed-loop control, which is generally overlooked in many adaptive control systems. This design of the initial control gains is a compound search strategy called conditional linear matrix inequality (CLMI) approach with IROA (Improved random optimal algorithm), it leads to less complex designs than a standard LMI method by fuzzy Lyapunov function. Numerical studies of the tracking control of an uncertain inverted pendulum system demonstrate the effectiveness of the control strategy. From results of this simulation, the generalized fuzzy model reduces the rule number of T-S fuzzy model indeed.

摘要： The problem of enumerating the types of Boolean functions under the group of variable permutations and complementations was first stated by Jevons in the 1870s. but not solved in a satisfactory way until the work of Polya in 1940. This paper explains the details of Polya's solution. and also the history of the problem from the 1870s to the 1970s.

摘要： Background: Visualization software can expose previously undiscovered patterns in genomic data and advance biological science. Results: The Genoviz Software Development Kit (SDK) is an open source, Java-based framework designed for rapid assembly of visualization software applications for genomics. The Genoviz SDK framework provides a mechanism for incorporating adaptive, dynamic zooming into applications, a desirable feature of genome viewers. Visualization capabilities of the Genoviz SDK include automated layout of features along genetic or genomic axes;support for user interactions with graphical elements (Glyphs) in a map;a variety of Glyph sub-classes that promote experimentation with new ways of representing data in graphical formats;and support for adaptive, semantic zooming, whereby objects change their appearance depending on zoom level and zooming rate adapts to the current scale. Freely available demonstration and production quality applications, including the Integrated Genome Browser, illustrate Genoviz SDK capabilities. Conclusion: Separation between graphics components and genomic data models makes it easy for developers to add visualization capability to pre-existing applications or build new applications using third-party data models.
