    Stochastic Calculus with a Special Generalized Fractional Brownian Motion

    Get PDF
    This work is a first step toward developing a stochastic calculus theory with respect to the generalized fractional Brownian motion, which a recently introduced Gaussian process is extending both fractional and sub-fractional Brownian motions. A Malliavin divergence operator and a stochastic symmetric integral with respect to this process are defined, and sufficient integrability conditions are provided. Moreover, corresponding Ito formulas are established, then applied to introduce a generalized version of the fractional Black–Scholes option pricing model.

    Digital Object Identifier: Privatising Knowledge Governance through Infrastructuring

    Get PDF
    This chapter uses what has become arguably the most ubiquitous piece of thinking infrastructure, the Digital Object Identifier (DOI), as a point of entry to explore the infrastructuring of hegemonic power in knowledge circulation. The chapter opens with a technical explanation of the DOI, followed by a brief history of the formation of the organizations that undergird the DOI. Along with the other metric devices, emerging “norms'' and narratives about the DOI further reinforce its centrality and we spend time debunking these myths. We close by exploring and making visible the relational work that the DOI performs to enable and shape the development of surveillance publishing, a dominant mode of profit and cognitive extraction in the higher education and research market

    Moderate Deviations Principle and Central Limit Theorem for Stochastic Cahn-Hilliard Equation in Holder Norm

    Get PDF
    We consider a stochastic Cahn-Hilliard partial differential equation driven by a space-time white noise. In this paper, we prove a Central Limit Theorem (CLT) and a Moderate Deviation Principle (MDP) for a perturbed stochastic Cahn-Hilliard equation in Holder norm. The techniques are based on Freidlin-Wentzell’s Large Deviations Principle. The exponential estimates in the space of Holder continuous functions and the Garsia-Rodemich-Rumsey’s lemma plays an important role, an another approach than the Li.R. ¨and Wang.X. Finally, we estabish the CLT and MDP for stochastic Cahn-Hilliard equation with uniformly Lipschitzian coefficients.

    NASA's Earth Science Data and Information System (ESDIS) Project has been processing information for the registration of Digital Object Identifiers (DOI) for the last five years of which an automated system has been in operation for the last two years. The ESDIS DOI registration system has registered over 2000 DOIs with over 1000 DOIs held in reserve until all required information has been collected. By working towards the goal of assigning DOIs to the 8000+ data collections under its management, ESDIS has taken the first step towards facilitating the use of data citations with those products.

    Object unified identifier method in logistics resource integration

    Get PDF
    Purpose: The status which many programs for the object identifier are not incompatible with each other has become a bottleneck for integrating logistics resources. Scholars have done some relevant studies in terms of coding and conversion mechanisms, but the problem still has not got a better solution. The purpose of this study is to research how to make the object identifier programs compatible. Design/methodology/approach: Author proposed an object unified identifier (OUID) method based on OID and introduced the standard identification code in it, according to the problems of the object identifier in logistics resource integration. And the paper further designed the acquisition process of the resource basic information and location information, and analyzed the application environment of object unified identifier based on OID. Findings: OUID made up for the lack of location information in conversion mechanism, and avoided to promote new unified identifier standards at the same time. The supplement of the application environment provided an important support to solve the problems of poor communication caused by non-unified object identifier in the process of logistics resource integration. Originality/value: Using this method, each identification system not only can keep its own territory, but also can compatible with other object identifiers.Peer Reviewe

    Relationship between Sublinear Operators and their Subdifferentials for Certain Classes of Lipschitz Summability

    Get PDF
    Let SB(X, Y ) be the set of all bounded sublinear operators from a Banach space X into a complete Banach lattice Y ; which is a pointed convex cone not salient in Lip0(X, Y ). In this paper, we are interested in studying the relationship between T and its subdifferential ∇T (the set of all bounded linear operators u : X -→ Y such that u(x) ≤ T (x) for all x in X); concerning certain notions of Lipschitz summability. We also answer negatively a question posed previously concerning this type of relation in the linear case. For this, we introduce and study a new concept of summability in the category of Lipschitz operators, which we call ”super Lipschitz p-summing operators”. We prove some characterizations in terms of a domination theorem and some properties of this notion.
