摘要： 数字对象唯一标识符（digital object identifier,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,作为出版物的唯一标识。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,是一个永久和唯一的标识号。

摘要： Increasingly, ORCID, DOIs and other identifier systems that are open and community-governed are embedded in scholarly works and information systems, such as papers and citation indices. They could benefit research in many more ways than their current use in unambiguously tracking authors and published output. Take, for example, the manuscript-submission process. Authors must create a journal account, review submission requirements and upload their manuscript, which probably contains links to other important information. Journals need to find unconflicted reviewers. Payment contacts for open access might be required. By using persistent identifiers, most of the manual processes in this workflow can be semi-automated (see ***/2lnqibu). Expertise should not be wasted on mundane administrative tasks. Identifiers can also act as signposts and coordinates, guiding us to information sources and showing connections between research and researchers. They can increase the visibility of a study, its origins and its impact, and indicate where it is hosted and who to ask for access. Contributors, peer reviewers and supporting materials can all be linked to the published article. An important feature of identifiers is that they afford a wider understanding of the research landscape that does not compromise privacy or ‘ownership’ of the research itself — pertinent, for example, when the work is ongoing, personal or competitive.

摘要： Cell type classification and handling is a key issue for understanding biological systems. The advent of high multiplexing technologies increased the complexity of the classification process and new tools are needed to support the organization of this knowledge. Ipropose a classification based on both prime numbers and the fundamental theorem of arithmetic. As a not limiting example, I show the application of this method to unambiguously define any existing cell type using the CD nomenclature established by the Human Leukocyte Differentiation Antigens Workshops. This system allows for the unique identification of any possible combination of markers hence any cell population without previous knowledge and without the need to increment the system. This method can be the future basis of any database and ontology system dealing with cell types and beyond the biological field applies to the description of any entity characterized by a list of discrete qualities.

关键词： Routing   distributed denial-of-service attacks   path identifiers  

摘要： In recent years, there are increasing interests in using path identifiers (PIDs) as inter-domain routing objects in the future Internet. While PIDs are advertised throughout the Internet in some future Internet architectures, they are kept secret in others. In this paper, we investigate the benefits, from the perspective of preventing distributed denial-of-service (DDoS) attacks, of keeping PIDs secret in future Internet when compared with advertising them throughout the Internet. Our results from extensive simulations show that keeping PIDs secret significantly helps prevent DDoS attacks.

摘要： The most convenient solution to link faraway significant renewable energy sources (RESs) is the voltage-source converter multi-terminal high-voltage DC systems (MT-HVDC). However, to maintain system stability and continuity of supply, a rigid and fast fault locating technique is required. This study proposes a novel inherent travelling waves based short-circuit DC fault identifier, which accurately identifies both of the fault location and faulty pole in multiple numbers of cables in MT-HVDC system using a single current sensor. Both of a discrete wavelet examiner and a fuzzy-neural pattern recogniser precisely spot the faulty line and fault location based on the mutual effects of short-circuit initiated travelling waves between lines belonging to the same loop. A software toolbox is structured to illustrate the adequacy of the proposed artificial intelligence technique. This method is valuable to MT-HVDC administration centres, particularly those concerned with long-distance RES.

摘要： The Reaction InChI (RInChI) extends the idea of the InChI, which provides a unique descriptor of molecular structures, towards reactions. Prototype versions of the RInChI have been available since 2011. The first official release (RInChI-V1.00), funded by the InChI Trust, is now available for download (http://***/downloads/). This release defines the format and generates hashed representations (RInChIKeys) suitable for database and web operations. The RInChI provides a concise description of the key data in chemical processes, and facilitates the manipulation and analysis of reaction data.
