PURPOSE To compare the added value of dynamic contrast material-enhanced ( CE contrast enhanced ) ( DCE dynamic CE ) magnetic resonance (MR) imaging with that of dynamic susceptibility CE contrast enhanced ( DSC dynamic susceptibility CE ) MR imaging with the combination of CE contrast enhanced T1-weighted imaging and diffusion-weighted ( DW diffusion weighted ) imaging for predicting recurrent...

Code deficiencies and bugs constitute an unavoidable part of software systems. In safety-critical systems, like aircrafts or medical equipment, even a single bug can lead to catastrophic impacts such as injuries or death. Formal verification can be used to statically track code deficiencies by proving or disproving correctness properties of a system. However, at its current state formal verific...

The research described in this work can significantly simplify and facilitate the creation and configuration of secure access control rule sets. Access control is used to provide confidential data or information only to authorized entities and deny access otherwise. Access control mechanisms can be configured with access control rule sets that need to be created and maintained by the users or a...

Today, the PC is only one of many ways to access information resources. Traditional computing technology has become more mobile and ubiquitous and more and more computing tasks are possible to do using new types of mobile devices. According to Siau, Lim, and Shen (2001), the essence of m-commerce (also termed “mobile information systems”) is to reach customers, suppliers, and employees regardle...

Background The diagnostic accuracy of diffusion-weighted imaging (DWI) to detect prostate cancer is well-established. DWI provides visual as well as quantitative means of detecting tumor, the apparent diffusion coefficient (ADC). Recently higher b-values have been used to improve DWI's diagnostic performance. Purpose To determine the diagnostic performance of high b-value DWI at detecting prost...

Recursive queries are required for many tasks of database applications. Among them we can mention Bill-Of-Material (BOM), various kinds of networks (transportation, telecommunication, etc.), processing semistructured data (XML, RDF), and so on. The support for recursive queries in current query languages is limited. In particular, this concerns corresponding extensions of SQL in Oracle and DB2 ...

Configuration is perhaps the most important aspect of a firewall. It is often hard to fully understand the implications of a given configuration, giving rise to two problems: it is hard to write rules to enforce the expected security policy correctly, and it is hard to understand a set of rules to make necessary changes. In this paper, we briefly introduced the IP packet filtering firewall foll...
