Comparison of fast-track diagnostics respiratory pathogens multiplex real-time RT-PCR assay with in-house singleplex assays for comprehensive detection of human respiratory viruses

Fast-track Diagnostics respiratory pathogens (FTDRP) multiplex real-time RT-PCR assay was compared with in-house singleplex real-time RT-PCR assays for detection of 16 common respiratory viruses. The FTDRP assay correctly identified 26 diverse respiratory virus strains, 35 of 41 (85%) external quality assessment samples spiked with cultured virus and 232 of 263 (88%) archived respiratory specimens that tested positive for respiratory viruses by in-house assays. Of 308 prospectively tested respiratory specimens selected from children hospitalized with acute respiratory illness, 270 (87.7%) and 265 (86%) were positive by FTDRP and in-house assays for one or more viruses, respectively, with combined test results showing good concordance (K=0.812, 95% CI = 0.786-0.838). Individual FTDRP assays for adenovirus, respiratory syncytial virus and rhinovirus showed the lowest comparative sensitivities with in-house assays, with most discrepancies occurring with specimens containing low virus loads and failed to detect some rhinovirus strains, even when abundant. The FTDRP enterovirus and human bocavirus assays appeared to be more sensitive than the in-house assays with some specimens. With the exceptions noted above, most FTDRP assays performed comparably with in-house assays for most viruses while offering enhanced throughput and easy integration by laboratories using conventional real-time PCR instrumentation.

Dynamic symmetry loss of high-frequency hysteresis loops in single-domain particles with uniaxial anisotropy

Understanding how magnetic materials respond to rapidly varying magnetic fields, as in dynamic hysteresis loops, constitutes a complex and physically interesting problem. But in order to accomplish a thorough investigation, one must necessarily consider the effects of thermal fluctuations. Albeit being present in all real systems, these are seldom included in numerical studies. The notable exceptions are the Ising systems, which have been extensively studied in the past, but describe only one of the many mechanisms of magnetization reversal known to occur. In this paper we employ the Stochastic Landau-Lifshitz formalism to study high-frequency hysteresis loops of single-domain particles with uniaxial anisotropy at an arbitrary temperature. We show that in certain conditions the magnetic response may become predominantly out-of-phase and the loops may undergo a dynamic symmetry loss. This is found to be a direct consequence of the competing responses due to the thermal fluctuations and the gyroscopic motion of the magnetization. We have also found the magnetic behavior to be exceedingly sensitive to temperature variations, not only within the superparamagnetic-ferromagnetic transition range usually considered, but specially at even lower temperatures, where the bulk of interesting phenomena is seen to take place.

Gestione del copyright nel tool autore AContent.

Con l’avvento di Internet, potentissimo strumento tecnologico di diffusione di informazioni e di comunicazione a distanza, anche le modalità di apprendimento sono cambiate: persino nelle scuole si tende a non utilizzare più i classici libri di testo, ma ad utilizzare dispositivi dai quali scaricare in formato elettronico, libri, dispense, test, video ed ogni altro genere di materiale di apprendimento, dando vita a un vero e proprio nuovo modo di apprendere chiamato E-learning, più veloce, comodo e ricco di alternative rispetto al vecchio modello offline che si presentava sottoforma di floppy inizialmente e poi di CD-ROM. E-learning significa, electronic based learning, ed è appunto una vera e propria metodologia di didattica che sfrutta e viene facilitata da risorse e servizi disponibili e accessibili virtualmente in rete. Al momento vi sono numerose piattaforme di E-learning, una delle quali è il nucleo di questa tesi, ovvero il tool autore AContent. Questo documento di tesi, infatti, raccoglie la descrizione della progettazione e della fase implementativa della gestione delle politiche di copyright per il tool AContent. L’obbiettivo è quello di rendere possibile l’assegnazione di un copyright a qualsiasi tipo di materiale didattico venga creato, caricato e/o condiviso sulla piattaforma in questione. Pertanto l’idea è stata quella di dare la possibilità di scegliere fra più copyright preimpostati, utilizzando degli standard di licenze riguardanti i diritti d’autore, lasciando anche l’opportunità di inserire la propria politica.

The International Three-Step Test. A Model Provision for EC Fair Use Legislation

The three-step test is central to the regulation of copyright limitations at the international level. Delineating the room for exemptions with abstract criteria, the three-step test is by far the most important and comprehensive basis for the introduction of national use privileges. It is an essential, flexible element in the international limitation infrastructure that allows national law makers to satisfy domestic social, cultural, and economic needs. Given the universal field of application that follows from the test’s open-ended wording, the provision creates much more breathing space than the more specific exceptions recognized in international copyright law. EC copyright legislation, however, fails to take advantage of the flexibility inherent in the three-step test. Instead of using the international provision as a means to open up the closed EC catalogue of permissible exceptions, offer sufficient breathing space for social, cultural, and economic needs, and enable EC copyright law to keep pace with the rapid development of the Internet, the Copyright Directive 2001/29/EC encourages the application of the three-step test to further restrict statutory exceptions that are often defined narrowly in national legislation anyway. In the current online environment, however, enhanced flexibility in the field of copyright limitations is indispensable. From a social and cultural perspective, the web 2.0 promotes and enhances freedom of expression and information with its advanced search engine services, interactive platforms, and various forms of user-generated content. From an economic perspective, it creates a parallel universe of traditional content providers relying on copyright protection, and emerging Internet industries whose further development depends on robust copyright limita- tions. In particular, the newcomers in the online market – social networking sites, video forums, and virtual worlds – promise a remarkable potential for economic growth that has already attracted the attention of the OECD. Against this background, the time is ripe to debate the introduction of an EC fair use doctrine on the basis of the three-step test. Otherwise, EC copyright law is likely to frustrate important opportunities for cultural, social, and economic development. To lay groundwork for the debate, the differences between the continental European and the Anglo-American approach to copyright limitations (section 1), and the specific merits of these two distinct approaches (section 2), will be discussed first. An analysis of current problems that have arisen under the present dysfunctional EC system (section 3) will then serve as a starting point for proposing an EC fair use doctrine based on the three-step test (section 4). Drawing conclusions, the international dimension of this fair use proposal will be considered (section 5).

Richtungsweisend oder eine nur begrenzt wahrgenommene Chance? Der Copyright-Code des Wittem-Projekts

Der „European copyright code“ des Wittem-Projekts von 4/2010 ist pragmatisch, konstruktiv-konservativ ausgefallen. Traditionell das Werk- und Autorenverständnis. Schrankenregelungen werden über einen hybriden Ansatz offen gehalten. Bildung und Wissenschaft werden nicht gerade verwöhnt. Die Wittem-Gruppe hat sich nicht in den „Treibsand visionärer Modelle“ begeben wollen. Ein guter Text, aber dann doch nicht wirklich wegweisend für den Umgang mit Wissen und Information in elektronischen Räumen, am ehesten noch durch den Vorschlag einer Schrankenbestimmung zur Begünstigung des wirtschaftlichen Wettbewerbs.

The Law Applicable to Online Copyright Infringements int ALI and CLIP Proposals: A Rebalance of Interest Needed?

The article discusses the problems of applicable law to copyright infringements online. It firstly identifies the main problems related to the well established territoriality principle and the lex loci protectionis rules. Then; the discussion focuses on the "ubiquitous infringement" rule recently proposed by the American Law Institute (ALI) and the European Max Planck Group for Conflicts of Law and Intellectual Propoperty (CLIP). The author strongly welcomes a compromise between the territoriality and universality approaches suggested in respect of ubiquitous infringement cases. At the same time; the paper draws the attention that the interests of "good faith" online service providers (such as legal certainty and foreseeability) have been until now underestimated and invites to take these interests into account when merging the projects into a common international proposal.

Liability for Copyright Infringements on the Internet: Host Providers (Content Providers) - The Geman Approach

Copyright infringements on the Internet affect all types of media which can be used online: films, computer games, audio books, music, software, etc. For example, according to German studies, 90% of all copyright violations affecting film works take place on the Internet. This storage space is made available to such infringers, as well as to others whose intentions are legal, by hosting providers. To what extent do hosting providers have a duty of care for their contribution to the copyright infringements of third parties, i.e. their users? What duties of care can be reasonably expected of hosting providers to prevent such infringements? These questions have been heavily debated in Germany, and German courts have developed extensive case law. This article seeks to examine these questions by assessing German jurisprudence against its EU law background.

Proposed WIPO Treaty for Improved Access for Blind, Visually Impaired, and Other Reading Disabled Persons

Although the world’s attention has on several occasions been turned to the plight of the vision impaired, there has been no international copyright instrument that specifically provides for limitations or exceptions to copyright for their benefit. Such an instrument becomes imperative amidst the grow- ing number of persons in this category and the need to facilitate their access to information that will give them the opportunity to participate in public affairs. Brazil, Ecuador, Paraguay, and Mexico (Brazilian group) seek to fill this gap by submitting to the WIPO’s Standing Committee on Copyright and Related Rights a draft treaty for Improved Access for Blind, Visually Impaired and Other Reading Disabled Persons. How- ever, this proposal has generated a lot of reactions, resulting in three other such proposals being submit- ted to WIPO for deliberations. Copyright owners have also opposed the treaty. Amidst these reactions, this work seeks to analyze the compatibility of the Brazilian group’s proposal with the TRIPS three-step test, which has enjoyed a great deal of international recognition since its inclusion in the Berne Convention. It also seeks to find its compatibility with EU copyright law as harmonized in the Directive 2001/29/EC. In the end, we conclude that the proposed treaty is in harmony with the three-step test, and though it has some variations from the EU Copyright Directive, it nonetheless shares some underlying objectives with the Directive and does not radically depart from what prevails in several EU member states.

Diverse Readings of the Court of Justice Judgments on Copyright Work

EU law’s impact on the meaning of the copyright work for a long time seemed limited to software and databases. But recent judgments of the CJEU (Infopaq, BSA, FootballAssociation [Murphy], Painer) suggest we have entered an era of harmonization of copyright subject-matter, after decades of focus on the scope of exclusive rights and their duration. Unlike before however, it is the Court and not the legislator that takes centre stage in shaping pivotal concepts. This article reviews the different readings and criticisms the recent case law on copyright works evokes in legal doctrine across the EU. It puts them in the wider perspective of the on-goingdevelopment towards uniform law and the role of the preliminary reference procedure in that process.

Copyright, Interfaces, and a Possible Atlantic Divide

Recent copyright cases on both sides of the Atlantic focused on important interoperability issues. While the decision by the Court of Justice of the European Union in SAS Institute, Inc.v. World Programming Ltd. assessed data formats under the EU Software Directive, the ruling by the Northern District of California Court in Oracle America, Inc. v. Google Inc. dealt with application programming interfaces. The European decision is rightly celebrated as a further important step in the promotion of interoperability in the EU. This article argues that, despite appreciable signs of convergence across the Atlantic, the assessment of application programming interfaces under EU law could still turn out to be quite different, and arguably much less pro-interoperability, than under U.S. law.
