The origin of platelet fibrinogen is controversial. It may arise from two sources: (a) exogenously by endocytosis of plasma fibrinogen, or (b) endogenously by synthesis. We explored the second possibility because we previously demonstrated that the first mechanism does occur. Fibrinogen synthesis by human megakaryocytes (MK) was investigated by in situ hybridization and the polymerase chain rea...

We present an approach for formal veriication of the DC and low frequency behavior of synthesized analog designs containing linear components and components whose behavior can be represented by piecewise linear models. A formal model of the structural description of a synthesized design is extracted from the sized component netlist produced by the synthesis tool, in terms of characteristic beha...

Mass spectra of methyl esters of ,three common drinking water chlorination by-products, bromodichloroacetic acid, dibromochloroacetic acid and tribromoacetic acid, are presented. The spectra are obtained in electron impact and chemical ionization modes, using a quadrupole mass spectrometer. Proposed fragment ion assignments are presented in detail. Fragment clusters were identified from their r...

Acknowledgments, e.g., “yeah” and “uh-huh,” are ubiquitous in human conversation but are rarer in human-computer interaction. What interface factors might contribute to this difference? Using a simple spoken-language interface that responded to acknowledgments, we compared subjects’ use of acknowledgments when the interface used recorded speech with that seen when the interface used synthesized...

A series of polymer chemosensors containing naphthalimide signal moiety and imide recognition moiety for the selective detection of fluoride ions (F(-) ) were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The polymer chemosensors display obvious absorption and fluorescence variations upon the addition of F(-) , which can be observed by both naked eyes an...

In this paper, we propose a general approach to audio segment retrieval using synthesized HMMs. The approach allows a user to query audio data of any length by one or more example audio segments and find similar segments. The basic idea of our approach is to first train a theme HMM using the given examples and a general background HMM using all the audio data, and then combine these individual ...

XML repositories are a common means for storing documents that are available through Web technologies. As the use of XML increases, there is a need to integrate XML repositories with other data sources to supply XML-oriented applications. In this paper, we examine documents that express business rules in XML format, and where the triggering and instantiation of rules requires execution of datab...

1203 of the standard FFT (for N < 16, the Dirichlet kernel interpolation is always more efficient). It is also worth noting that for these values, and small N , the CP is more attractive than the Yaroslavsky; otherwise, there is little computational difference between the two FFT-based methods. In addition, as N decreases, the computational saving introduced by using the Dirichlet kernel, inste...

This paper considers the reliability of usual assessment methods when evaluating virtual synthesized views in the multiview video context. Virtual views are generated from Depth Image Based Rendering (DIBR) algorithms. Because DIBR algorithms involve geometric transformations, new types of artifacts come up. The question regards the ability of commonly used methods to deal with such artifacts. ...
