PURPOSE To develop a fully quantitative 4D transcatheter intraarterial perfusion (TRIP) magnetic resonance imaging (MRI) technique and prospectively test the hypothesis that quantitative 4D TRIP-MRI can be used clinically to monitor intraprocedural liver tumor perfusion reductions during transcatheter arterial chemoembolization (TACE). MATERIALS AND METHODS TACE was performed within an x-ray ...

With the development of wireless technology, many handheld computers provide the learners with platform and resources to interact, collaborate, and share ubiquitously. The purpose of this research is to explore the potential application of mobile technologies in supporting elementary students' learning in the field trip. By recording the path of traversing, the GPS and GIS offer hyperlinked to ...

We are investigating printed symbols as a tangible representation of Web services, to allow mobile users to identify and interact with local services available in (foreign) pervasive environments. We have extended the TRIP symbol recognition algorithm to allow larger address spaces for this purpose, and have implemented a prototype on a desktop computer. We present the results of testing recogn...

This paper describes the setup of the Dutch Mobile Mobility Panel project, in which GPSenabled mobile phones (smartphones) are used as a passive multiple-week and multipleyear travel behaviour data collection tool. The data collection methodology used in the Dutch Mobile Mobility Panel comprised firstly the development of a smartphone application for iPhone and Android smartphones that automati...

This paper presents FLOWTEST a concept on testing interorganizational workflows on model-level. FLOWTEST focuses on building up test-models, deriving test-cases and executing tests on predefined workflows consisting of atomic web-services. The main goal of FLOWTEST is the realization of a test-suite to drive round-trip testing from code to model back to code level.

BACKGROUND A key public health objective is increasing health-enhancing physical activity (PA) for older adults (OAs). Daily trip frequency is independently associated with objectively assessed PA volumes (OAs). Little is known about correlates and these trips' transport mode, and how these elements relate to PA. PURPOSE to describe the frequency, purpose, and travel mode of daily trips in OA...

TRIP-Br3 and TRIP-Br1 have shown to have important biological functions. However, the function of TRIP-Br3 in tumorigenesis is not well characterized compared to oncogenic TRIP-Br1. Here, we investigated the function of TRIP-Br3 in tumorigenesis by comparing with that of TRIP-Br1. Under nutrient/serum starvation, TRIP-Br3 expression was down-regulated slightly in cancer cells and significantly ...

This paper addresses the problem of characterizing analytically the autocorrelation structure of TCP traffic. We show that, under simple models, a single TCP connection generates traffic with an exponentially decreasing autocorrelation function. However, several TCP connections sharing a given link can generate traffic with long term dependencies, under the condition that the distribution of th...
