BACKGROUND The current method of analyzing myocardial cell transplantation relies on postmortem histology. We sought to demonstrate the feasibility of monitoring transplanted cell survival in living animals using molecular imaging techniques. METHODS AND RESULTS For optical bioluminescence charged-coupled device imaging, rats (n=20) underwent intramyocardial injection of embryonic rat H9c2 ca...

This paper presents the implementation of March Algorithm based Memory Built-In Self Test (MBIST) architecture for Static Random Access Memory (SRAM). A Finite State Machine (FSM) is designed to implement March – based Test algorithm. Also SRAM block and the interfacing modules are presented. There is a standard March Test Algorithm with 22N where N is the number of memory words, read/write ope...

Nuclear cardiology is an extremely important modality in the management of coronary artery disease. Information about myocardial perfusion , myocardial function, myocardial metabolism, myocardial innervation, myocardial infarction and apoptosis , atherosclerosis and gene therapy can be obtained with nuclear cardiology scans.Nuclear cardiology involves use of radiopharmaceuticals to study the fu...

High-order methods gain more and more attention in computational fluid dynamics. However, the potential advantage of these methods depends critically on the availability of efficient elliptic solvers. With spectralelement methods, static condensation is a common approach to reduce the number of degree of freedoms and to improve the condition of the algebraic equations. The resulting system is b...

Positron emitters such as 11C, 13N and 18F and their labelled compounds are widely used in clinical diagnosis and animal studies, but can also be used to study metabolic and physiological functions in plants dynamically and in vivo. A very particular tracer molecule is CO2 since it can be applied to a leaf as a gas. We have developed a Plant Tomographic Imaging System (PlanTIS), a high-resoluti...

In this paper, I explore sequential approaches to triangular matrix inversion (TMI). TMI is commonly performed when calculating the explicit inverse of a (dense) matrix from its LU factorization (cf. LAPACK xGETRI). Direct algorithms perform 13n 3 +O � n � flops, where the lower order terms depend on the specific implementation. Because of the structural relationship between a triangular matrix...

Background. Regional myocardial blood flow has been quantified using transaxial positron emission tomographic (PET) imaging and tracer kinetic modeling. However, the use of transaxial images limits the accuracy of regional partial volume corrections and the localization of the quantified regional flow values. The purpose of the present study was to overcome both problems by calculating regional...
