Conventional middleware architectures suffer from insufficient module-level reusability and the ability to adapt in face of func-tionality evolution and diversification. To overcome these deficiencies, we propose the Modelware methodology adopting the Model Driven Architecture (MDA) approach and aspect oriented programming (AOP). We advocate the use of(More)
The decoupling of producers and consumers in the pub-lish/subscribe paradigm lends itself well to the support of mobile users who roam about the environment with intermittent network connectivity. This paper presents the first quantitative evaluation of publisher mobility in a distributed publish/subscribe system. Our results indicate that publisher(More)
In this paper, some generalized mixed vector equilibrium problems in Banach spaces are introduced and the equivalence of two classes of -generalized mixed vector equilibrium problems is proved under suitable assumptions. By using the equivalence theorem, some results on the existence of solutions for -generalized mixed vector equilibrium problems are(More)
INTRODUCTION Accumulating evidence suggests that enhanced inflammatory responses contribute to the pathogenesis of postoperative cognitive dysfunction (POCD). Blood transfusion can trigger an enhancement of acute inflammatory responses. Therefore, we hypothesized that perioperative blood transfusion is associated with a higher risk of POCD in aged patients(More)
A 72-year-old male with a history of prostate cancer and high prostate specific antigen levels underwent 99m technetium-methylene diphosphonate (99m Tc-MDP) single-photon emission computed tomography/computed tomography (SPECT/CT), to identify bone metastasis. The patient possessed no previous history of serious illnesses or surgical procedures and no(More)

In this paper, we introduce the concepts of extended well-posedness for quasi-variational inequalities and establish some characterizations. We show that the extended well-posedness is equivalent to the existence and uniqueness of solutions under suitable conditions. In addition, the corresponding concepts of extended well-posedness in the generalized sense(More)
