The mediation is based on an essential component called mediator. The main role of the mediator is to reformulate a user query, written in terms of global schema, in queries written in terms of sources schemas. This paper describes an algorithm for reformulation of XQuery queries. The algorithm is based on the principle of logical equivalence, simple and complex unification, to obtain a better ...

Mediation analysis has been a popular framework for elucidating the mediating mechanism of exposure effect on outcome in many disciplines including genetic studies. Previous literature causal mediation primarily focused classical settings with univariate and mediator, recent growing interests high-dimensional mediator. In this paper, we study model exposure, continuous outcome. We introduce two...

So as to explore the mediator effect of green technologic innovation on impact digital economic circulation industry, based panel data 30 provinces in China from 2011 2019, this paper constructs a fixed model and for empirical analysis. The results show that significantly boosts advance industry; through test, it is found can boost industry innovation, 57.28 %. Finally, aspects strengthening ta...

This paper presents a novel architectural solution for improving dependability of Web Services. This approach is based on the concepts from the emerging resilienceexplicit computing combined with the traditional fault-tolerance techniques such as recovery blocks and N-version programming applied in the context of the serviceoriented architecture. We propose a distributed solution called WS-Medi...

Recent advances in the causal inference literature on mediation have extended traditional approaches to direct and indirect effects to settings that allow for interactions and non-linearities. In this article, these approaches from causal inference are further extended to settings in which multiple mediators may be of interest. Two analytic approaches, one based on regression and one based on w...

The monoolein-based liquid crystalline cubic phase was used as the matrix to incorporate redox enzymes--glucose (GOx), pyranose (PyOx) oxidases and laccase. Thin layer of the cubic phase embedding GOx or PyOx activated glucose oxidation in the presence and absence of appropriate mediators. The electrodes exhibited unchanged voltammetric response to glucose for not less than six days. The potent...
