摘要： This part of ISO/IEC 15459 specifies a unique, non-significant string of characters for the unique identifier ofproduct groupings. The character string is intended to be represented in linear bar code and two-dimensionalsymbols, radio frequency identification (RFID) transponder or other automatic identification and data capture(AIDC) media attached to the product and/or material to meet the management needs in a batch or lot unit. Toaddress management needs, different classes of item are recognised in the various parts of ISO/IEC *** allows different requirements to be met by the unique identifiers of each *** unique identifier for product grouping enables a product grouping defined by a batch or lot number to beuniquely identified from all other lots and batches compliant with this part of ISO/IEC 15459. Encoding thisunique identifier in a data carrier enables information about the quality of product and end-of-life processing tobe clearly *** rules for the unique identifier for product grouping, to identify the unique occurrence of that quality, aredefined and supported by an example.

摘要： This part of ISO/IEC 15459 specifies a unique, non-significant string of characters for the unique identificationof returnable transport items (RTIs). The character string is intended to be represented in a radio frequencyidentification (RFID) transponder, bar code label or other automatic identification and data capture (AIDC)media attached to the item to meet supply chain management needs. To address management needsdifferent classes of RTI are recognised in the various parts of ISO/IEC 15459, which allows differentrequirements to be met by the unique identifiers associated with each class. The rules for the unique identifierfor RTIs, to identify the unique occurrence of an item, with the identity being relevant for the complete lifecycle of the item, are defined and supported by an example.

摘要： XML数据库模式规范化设计是产生一组相关联的、能表示数据间依赖关系、而且消除了冗余的XML模式或DTD,其目的是为了互联网上的信息检索能够避免异常. XML数据库模式中某些数据依赖的存在是冗余存在的原因,因此在XML数据库模式中数据依赖与冗余的关联是其规范化设计研究的关键问题. XML数据库模式的数据依赖包括属性间数据依赖和元素间的数据依赖,与之关联的结构冗余和不规则是指在XML模式的结构上存在冗余和不规则的情况.给出综合了属性间和元素间数据依赖的XML数据库模式数据依赖的定义,分析与之关联的结构冗余以及不规则的情况,基于此定义消除结构冗余和不规则的规范的XML模式森林作为范式,给出并验证其规范化设计算法.

关键词： Authentication  

摘要： In this work, we describe a method for establishing authenticated channels in a wireless ad-hoc network. The presented protocol is fully self-organized, and it also pro- vides an identification framework. The two main contributions are (1) a fully self-organized protocol that establishes an authenticated communication channel between nodes of a wireless ad-hoc network and (2) a secure identifier framework that is resilient to impersonation. The authenticated channel provided by the protocol can then be used to establish a secret communication channel between nodes. The authentic identifiers established can be used to associate network (and upper) layer identifiers to prevent spoofing. They can also serve as a reliable basis for reputation management protocols. The paper analyzes the proposed approach in terms of security and complexity (both communication and storage).

关键词： essential tremor   health outcomes research   ICD-9  

摘要： Background/Aims: Health outcomes research often uses administrative databases. Patients with the diseases of interest are identified using International Classification of Diseases ( ICD- 9 CM) codes. The utility of the code for essential tremor ( ET), 333.1, remains untested. We determined the positive predictive value ( PPV) of the code 333.1. Methods: Patients with the ICD- 9 CM code 333.1 were identified from billing records at the Neurological Institute of New York. Their medical records were reviewed to determine whether they met Consensus Criteria for ET. Results: Of 964 patients who carried the code 333.1, only 472 met diagnostic criteria for ET (i.e. PPV = 49.0%). The additional use of ICD 9- CM codes for parkinsonism and dystonia ( as exclusionary criteria) only marginally improved this value ( 57.8%). Common diagnoses among the false positives were Parkinson's disease, dystonia, enhanced physiological tremor, drug-induced tremor, orthostatic tremor, and psychogenic tremor. Patients seen by general neurologists ( vs. movement disorder specialists) were half as likely to meet diagnostic criteria for ET ( 34.6 vs. 51.9%, OR 0.50, 95% CI 0.23 - 0.70, p < 0.001). Conclusion: The code 333.1 performed poorly when attempting to identify ET cases. Given the very high prevalence of ET, a unique diagnostic code would seem to be in order. Copyright (C) 2007 S.

关键词： Digital signal processing  

摘要： Automatic digital-signal-type identification plays an important role for various applications. This paper presents a highly efficient identifier ( technique) that identifies a variety of digital signal types. In this technique, a selected number of the higher-order moments and the higher-order cumulants up to eighth are utilized as the effective features. A hierarchical support-vector-achine(SVMs) based structure is proposed for multiclass classification. A genetic algorithm is proposed in order to improve the performance of the identifier. Genetic algorithm selects the suitable parameters of SVMs that are used in the structure of the classifier. Simulation results show that the proposed identifier has high performance for identification of the considered digital signal types even at very low SNRs.

摘要： Protein tyrosine phosphatase (PTP gamma) is a receptor-like molecule with a known role in murine hematopoiesis. We analyzed the regulation of PTP gamma expression in the human hematopoietic system, where it was detected in human peripheral blood monocytes and dendritic cells (DCs) of myeloid and plasmacytoid phenotypes. Its expression was maintained during in vitro monocyte differentiation to dendritic cells (moDC) and was further increased after maturation with bacterial lipopolysaccharide (LPS), CID40L, and TNF alpha. But PTP gamma was absent when monocytes from the same donor were induced to differentiate in macrophages. B and T lymphocytes did not express PTP gamma. Rather, PTP gamma mRNA was expressed in primary and secondary lymphold tissues, and the highest expression was in the spleen. PTP gamma was detected by immunohistochemistry in subsets of myeloid-derived DCs and specialized macrophages (tingible bodies, sinus and alveolar macrophages). Classic macrophages in infective or reactive granulomatous reactions did not express PTP gamma. Increased PTP gamma expression was associated with a decreased ability to induce proliferation and interferon-gamma secretion in T cells by moDCs from patients with advanced pancreatic cancer. Taken together, these results Indicate that PTP gamma is a finely regulated protein in DC and macrophage subsets In vitro and in vivo.
