The 29-residue ribonucleotide primer formed by primase at the origin of phage G4 DNA replication (Bouché, J.-P, Rowen, L., and Kornberg, A. (1978) J. Biol. Chem. 253, 765-769) was shorter in the presence of deoxynucleoside triphosphates (dNTPs). At 50 micrometer dNTPs and 20 micrometer rNTPs, RNA trancripts no longer than 6 residues were synthesized and these were still effective in priming rep...

This paper presents a perceptual experiment on the friendliness of the synthesized Standard Chinese. Based on the acoustic investigation of friendly speech, tonal pitch, phone duration and spectral energy distribution were adjusted in synthesis and the synthesized stimuli were subjected to perception test. It was found that: (1) Friendliness of synthesized speech could be achieved via adjusting...

We have earlier reported the enzymatic synthesis of RNA from the four riboside triphosphates by a DNA-containing nucleoprotein of pea embryos.I Since the nucleoprotein contains the bulk of the tissue DNA and since it resembles in composition and properties the chromatin obtained directly from the nuclei of pea embryos,2 we refer to the synthetically active material as chromatin. The RNA newly f...

It was previously observed [1] that the order of presentation of paired stimuli influenced the number of different responses in same-different tasks in speech synthesis evaluation. This paper investigates this phenomenon within the context of cognitive psychology and demonstrates that, as the cognitive psychology literature suggests, there is an effect relating to the prototypicality of the sti...

Since the early 70’s there has been a proliferation of literature about telework. A significant portion of these books and articles focus on, promote, or at least list the benefits of this alternative work style. At the same time there are a number of studies indicating that the rate of adoption of telework is well below levels predicted by proponents. Noticeably lacking in the literature are e...

Virtual worlds provide 3D-immersive experiences to users and some of them already have already launched commercial service to users. As computing environment becomes more heterogeneous, more mobile users are anticipated to access the virtual world with their mobile devices. However, still there are challenges and problems to be addressed for mobile users. In this report, state-of-art virtual wo...

Concatenative synthesis concatenates segments of prerecorded natural human speech. It requires database of previously recorded human speech covering all the possible segments to be synthesised. Segment might be phoneme, syllable, word, phrase, or any combination. Concatenative speech synthesis is currently the most practical method for the generation of realistic speech. There mainly two types ...

In this paper, we present the results of a study designed to investigate the visual factors which contribute to the perceived quality of synthesized textures. A psychophysical experiment was performed in which subjects rated the quality of textures synthesized from a variety of modern texture-synthesis algorithms. The ratings were given in terms of how well each synthesized texture represented ...

Very small amounts of adrenocorticosteroids are synthesized by brain tissue in vitro. While there is evidence suggesting that the synthesis of aldosterone in the brain may have a role in the hypertension of the Dahl salt-sensitive rat, the de novo synthesis of aldosterone or corticosterone within the brain of a living animal has not been demonstrated. We have used sensitive ELISAs to measure al...
