In a clinical perspective better methods to identify subjects at increased cardiovascular risk are needed. Atherosclerotic plaques of the carotid arteries with low echogenicity have been related to future clinical events. However, better methods to assess plaque characteristics are needed as well as more information on the variability and change over time of echogenicity in relation to occurren...

1 Abstract—This paper addresses the problem of fine-grained data replication on a set of Internet sites using the N+1 price auction. Specifically, we present an adaptive auction mechanism for replication of objects in a distributed system. The mechanism is adaptive in the sense that it changes the replica schema of the objects by continuously moving the schema towards an optimal one, while ensu...

short story is one of the newborn literary genres that has drawn special attention of  literary men and researchers to itself in recent years because of its general effect on literature and its special influence on reader of a literary work. this article investigates short story comparatively in arabic and persian literature. the aim of this paper is to discover latent aspects of short story in...

Li X.Y., Li Z.-X., Lin H., Samee H. (2011): Effect of power ultrasound on the immunoactivity and texture changes of shrimp (Penaeus vannamei). Czech J. Food Sci., 29: 508–514. The aim of this study was to examine the effect of power ultrasound on the allergenicity and texture properties of shrimp (Penaeus vannamei). For this purpose, raw and boiled shrimps were treated with power ultrasound (30...

Ensuring the energy efficiency, thermal safety, and security-awareness in today’s large-scale distributed computing systems is one of the key research issues that leads to the improvement of the system scalability and requires researchers to harness an understanding of the interactions between the system external users and the internal service and resource providers. Modeling these interactions...

Data sharing in large-scale Peer Data Management Systems (PDMS) is challenging due to the excessive number of data sites, their autonomous nature, and the heterogeneity of their schema. Existing PDMS query applications have difficulty to simultaneously achieve high recall rate and scalability. In this chapter, we propose an ontology-based sharing framework to improve the quality of data sharing...

In a smart home environment appliances and objects have sensing, actuating and wireless communication capabilities. Recent embedded middleware initiatives aim at providing an easy to use programming framework for developing applications that require the cooperation of sensing and actuating nodes. To achieve this, the mobile agent paradigm is adopted under which an application consists of a set ...

An upward drawing of a rooted tree T is a planar straight-line drawing of T where the vertices of T are placed on a set of horizontal lines, called layers, such that for each vertex u of T , no child of u is placed on a layer vertically above the layer on which u has been placed. In this paper we give a linear-time algorithm to obtain an upward drawing of a given rooted tree T on the minimum nu...

T Inn the last few years many patients have been reported with a defect in peroxisomal fatty acid P-oxidationn of unknown origin. Using a combined approach based on direct activity measurementss of straight chain acyl-CoA oxidase and complementation analysis after somatic cell fusionn of fibroblasts, we have now classified 13 patients into 4 distinct groups representing differentt gene defects....

Packing and Covering problems together capture many important problems in combinatorial optimization. We will consider covering problems in these notes. Two canonical covering problems are Vertex Cover and its generalization Set Cover. They play an important role in the study of approximation algorithms. A vertex cover of a graph G = (V,E) is a set S ⊆ V such that for each edge e ∈ E, at least ...
