Various methods for the recovery and detection of HAV have been suggested, and molecular tests have recently provided an effective replacement for the traditional methods. Real-time RT-PCR technology offers many advantages over conventional RT-PCR in terms of rapidity and specificity. Most procedures are based on the TaqMan chemistry, but some researchers have used the SYBR Green I approach, wh...

In this paper we describe the use of QE, a framework that aims to obtain predictions on the quality of translations, to improve the performance of machine translation (MT) systems without changing their internal functioning. We apply QE to experiments with: i. multiple system translation ranking, where translations produced by different MT systems are ranked according to their estimated q...

This work addresses the problem of cheating prevention in secret sharing. The scheme is said to be k-cheating immune if any group of k cheaters has no advantage over honest participants. In this paper we study the constraints of cheating immune secret sharing schemes. We give a necessary and sufficient condition for SSSs to be cheating immune. Then, we improve the upper bound of D’Arco et. al o...

Fluorescent monitoring of DNA amplification is the basis of real-time PCR, from which target DNA concentration can be determined from the fractional cycle at which a threshold amount of amplicon DNA is produced. Absolute quantification can be achieved using a standard curve constructed by amplifying known amounts of target DNA. In this study, the mathematics of quantitative PCR are examined in ...

The "testing effect" refers to the finding that after an initial study opportunity, testing is more effective for long-term retention than restudying. The testing effect seems robust and is a finding from the field of cognitive science that has important implications for education. However, it is unclear whether this effect also applies to the acquisition of problem-solving skills, which is imp...
