INTRODUCTION: Real-time MRI is indispensable for visualizing fast-evolving processes such as cardiac function. Successful real-time operation also imposes stiff requirements on software and hardware, including the need for efficient pulse sequences, optimized reconstruction routines, tight synchronization between software and scanner, high-speed low-latency data transfer, and an interactive use...

Vol. 35, No. 6 (2003) BioTechniques 1141 the ABI PRISM® 7000 and the TaqMan Universal PCR Master Mix protocols (Applied Biosystems). After discovering that the RNA from the thecal cells had vascular endothelial growth factor (VEGF) amplification and that RNA from granulosa cells had no VEGF amplification, the 18S rRNA amplification (TaqMan Pre-Developed Assay Reagents; Applied Biosystems), whic...

Recent years have seen significant demand for supporting real-time systems in virtualized environments as system integration become an increasingly important challenge for complex real-time systems. This paper presents RT-Xen, the first hierarchical real-time scheduling framework for Xen, the most widely used open-source virtual machine monitor (VMM). RT-Xen bridges the gap between hierarchical...

In this paper we present STAR-RT the first working prototype of Selective Tuning Attention Reference (STAR) model and Cognitive Programs (CPs). The Selective Tuning (ST) model received substantial support through psychological and neurophysiological experiments. The STAR framework expands ST and applies it to practical visual tasks. In order to do so, similarly to many cognitive architectures, ...

The real-time polymerase chain reaction (RT-PCR), also called quantitative real-time polymerase chain reaction (QRT-PCR) or kinetic polymerase chain reaction (kPCR), is a technique used to simultaneously quantify and amplify a DNA molecule. It is used to determine whether a specific DNA sequence is present in the sample; and if it is present, the number of copies in the sample. It is the real-t...

Koblitz curves have been a nice subject of consideration for both theoretical and practical interests. The window τ -adic algorithm of Solinas (window τNAF) is the most powerful method for computing point multiplication for Koblitz curves. Precomputation plays an important role in improving the performance of point multiplication. In this paper, the concept of optimal pre-computation for window...

Development of distributed real-time embedded systems is often a challenging task and validation of the timing behaviour of such systems is typically as important as its functional correctness. VDM-RT is a modelling language with an executable subset that can be used to describe distributed realtime embedded systems. In previous work [5], post-analysis of important timing constraints was achiev...

A real-time implementation of self-calibrating Generalized Autocalibrating Partially Parallel Acquisitions (GRAPPA) operator gridding for radial acquisitions is presented. Self-calibrating GRAPPA operator gridding is a parallel-imaging-based, parameter-free gridding algorithm, where coil sensitivity profiles are used to calculate gridding weights. Self-calibrating GRAPPA operator gridding's wei...
