  1. The Application of the Titanium-Catalyzed Hydroamination of Alkynes toward the Synthesis of Benzylisoquinoline Derivatives

    … of the aminoalkyne 123. Employing Noyori´s reduction protocol, the absolute configuration at C-1 of the benzylisoquinoline was introduced with 93% ee. Finally, methylation of norlaudanosine (146) by a reductive amination protocol afforded (+)-(S)-laudanosine (101). Alternatively, formation …

  2. Use of nitrous oxide as the terminal electron acceptor during growth and respiration of Bradyrhizobium Japonicum USDA 143

    … conditions. Cell growth and dissimilatory N₂O reduction were significantly inhibited by acetylene when either N₂O or N₂O plus nitrate served as terminal electron acceptor(s). Reduction of nitrous oxide accounted for 20% of the energy for cell growth in cultures supplied with nitrate as the …

  3. Social and Linguistic Factors Conditioning the Glottal Stop in Nicaraguan Spanish

    <p>This dissertation investigates the word-final, intervocalic glottal stop [ʔ] in Nicaraguan Spanish, a highly understudied variant in an equally understudied dialect of Spanish. The glottal stop occurs most frequently in western Nicaragua as an allophone of word-final, intervocalic /s/ (the …

  4. The Use of Language Models in End-to-End Spoken Language Processing

    … yields a 15.1% relative word error rate (WER) reduction on the cross-domain TED-LIUM 2 dataset compared with the best baseline, while substantially improving intra-domain performance on LibriSpeech. When applied to the online neural transducer, it achieves a 12.2% relative WER reduction over …
