In this paper, we propose an HMM trajectory-guided, real image sample concatenation approach to photo-real talking head synthesis. It renders a smooth and natural video of articulators in sync with given speech signals. An audio-visual database is used to train a statistical Hidden Markov Model (HMM) of lips movement first and the trained model is then used to generate a visual parameter trajec...

A scalable real-time asynchronous sample rate converter software kernel is presented that offers a flexible alternative to the usual hardware implementations. The kernel is dynamically configurable at run-time and supports almost arbitrary up-sampling or down-sampling ratios and any number of channels. Due to its scalability this sample rate converter kernel may be used both for low complexity,...

We demonstrate a real-time transient waveform digitizer with a record 1 TSa/s (TeraSample/sec) sampling rate. This is accomplished by using a photonic time stretch preprocessor which slows down the electrical waveform before it is captured by an electronic digitizer. * Present address: College of Optics and Photonics: CREOL & FPCE, University of Central Florida, 4000 Central Florida Blvd., Orla...

background: dna isolation procedure can significantly influence the quantification of dna by real time pcr specially when cell free dna (cfdna) is the subject. to assess the extraction efficiency, linearity of the extraction yield, presence of co-purified inhibitors and to avoid problems with fragment size relevant to cfdna, development of appropriate external dna control (edc) is challenging. ...

Population stratification is an important task in genetic analyses. It provides information about the ancestry of individuals and can be an important confounder in genome-wide association studies. Public genotyping projects have made a large number of datasets available for study. However, practical constraints dictate that of a geographical/ethnic population, only a small number of individuals...

using a sample fiom burr type xu distribution, bayes prediction intervals are derived for the maximum and minimum of a future sample fromthe same distribution, but in the presence of a single outlier of the type 8,8. the prior of q is assumed to be the gamma conjugate. a real example is given to illustrate the procedure. also, the comparison between the values of the prediction bounds for diffe...

Copy number variations (CNVs) can be used as significant bio-markers and next generation sequencing (NGS) provides a high resolution detection of these CNVs. But how to extract features from CNVs and further apply them to genomic studies such as population clustering have become a big challenge. In this paper, we propose a novel method for population clustering based on CNVs from NGS. First, CN...
