  • The Sonogashira cross-coupling reactions were used to synthesize 5 new monoalkynyl derivatives (10a-e) and 2 dialkynyl derivatives (12a-b) containing thieno[3,2-b]thiophene from monoaryl thieno[3,2-b]thiophen in moderate yield. The procedure was optimized and triphenylphosphine (0.2 eq.), palladium diacetate (0.1 eq), copper (I) iodide (0.2 eq.), THF, iPr2NH were found to be the best in these cases. The structures of the (10a-e) and (12a-b) compounds were elucidated by 1H and 13C NMR and mass spectral analysis.

  • The overall performance of the systems is often limited by the accuracy of the underlying speech parameterization and reconstruction method. The method proposed in this paper allows accurate MFCC, F0 and tone extraction and high-quality reconstruction of speech signals assuming Mel Log Spectral Approximation filter. Its suitability for high-quality HMM-based speech synthesis is shown through evaluations subjectively.

  • Hydrogenophilus thermoluteoluscytochromec¢ (PHCP) has typical spectral properties previously observed for other cytochromesc¢, which comprise Ambler’s class II cytochromesc. The PHCP protein sequence (135 amino acids) deduced from the cloned gene is the most homologous (55% iden-tity) to that of cytochrome c¢ from Allochromatium vinosum(AVCP).
