    Изложены авторские подходы к рассмотрению различных проявлений рисков инновационной деятельности, которые согласно авторской концепции следует рассматривать как сложную систему, включающую: этапы инновационного процесса; субъектов инновационного процесса, задействованных на каждом из этапов; элементарные риски отдельных субъектов, вызванные факторами макросреды, микросреды, а также внутренней среды; возможности и угрозы, являющиеся следствием риска. Предложен укрупненный алгоритм анализа инновационных рисков в русле системного подхода

    TellEat: sharing experiences on the move

    In a context where, due to the proliferation of mobile devices, virtual social environments on the Web are taking up a very concrete role in the way people experience their surroundings, the Future Internet seems to be headed toward a mixture of Social Web, Semantic Web and Augmented Reality. As a part of a larger project that aims at building a social network of both people and things, we designed and developed TellEat, an iPhone-based application that allows users in mobility to share facts concerning people or objects that participate in the social network, and to discover pertinent events that have been told by others. In this paper we discuss both the client application, with the interaction model and interface metaphors that have been designed to make the experience as playful as possible for users, and the server-side services that provide the necessary knowledge and reasoning mechanisms. We also present the results of preliminary tests with users

    Multicenter prevalence study comparing molecular and toxin assays for clostridioides difficile surveillance, Switzerland

    Public health authorities in the United States and Europe recommend surveillance for Clostridioides difficile infections among hospitalized patients, but differing diagnostic algorithms can hamper comparisons between institutions and countries. We compared surveillance based on detection of C. difficile by PCR or enzyme immunoassay (EIA) in a nationwide C. difficile prevalence study in Switzerland. We included all routinely collected stool samples from hospitalized patients with diarrhea in 76 hospitals in Switzerland on 2 days, 1 in winter and 1 in summer, in 2015. EIA C. difficile detection rates were 6.4 cases/10,000 patient bed-days in winter and 5.7 cases/10,000 patient bed-days in summer. PCR detection rates were 11.4 cases/10,000 patient bed-days in winter and 7.1 cases/10,000 patient bed-days in summer. We found PCR used alone increased reported C. difficile prevalence rates by <= 80% compared with a 2-stage EIA-based algorithm.Molecular basis of bacterial pathogenesis, virulence factors and antibiotic resistanc

    Spin-2 fields and helicity

    By considering the irreducible representations of the Lorentz group, an analysis of the different spin-2 waves is presented. In particular, the question of the helicity is discussed. It is concluded that, although from the point of view of representation theory there are no compelling reasons to choose between spin-2 waves with helicity = + - 1 or helicity = + - 2, consistency arguments of the ensuing field theories favor waves with helicity = + - 1.Comment: 10 pages.
