13. Automatic speech recognition, with large vocabulary, robustness, independence of speaker and multilingual processing
Este trabalho visa prover assistência cognitiva automática via interface de fala, à idosos que moram sozinhos, em situação de risco. Expressões de angústia e comandos vocais fazem parte do vocabulário alvo de reconhecimento de fala. Durante todo o trabalho, o sistema de reconhecimento de fala contínua de grande vocabulário Julius é utilizado em co

14. Ensaio clínico randomizado da preservação de enxertos hepáticos com solução de perfusão de UW e HTK no transplante ortotópico de fígado
Introdução: A solução de UW (University of Wisconsin) tem sido utilizada como padrão para preservação de enxertos hepáticos para transplante ortotópico de fígado (TOF) desde 1990. Seu custo é alto, e não existem, em nosso meio, estudos clínicos que comparem a sua efetividade com a de outras soluções. A solução de HTK (histidina-triptofano-ce

15. Conversion grapheme-phone for a system of recognition of voice with support the great vocabularies for the Brazilian Portuguese / Conversão grafema-fone para um sistema de reconhecimento de voz com suporte a grandes vocabulários para o português brasileiro
Speech processing has become a data-driven technology. Hence, the success of research in this area is linked to the existence of public corpora and associated resources, as a phonetic dictionary. In contrast to other languages such as English, one cannot find, in public domain, a Large Vocabulary Continuos Speech Recognition (LVCSR) System for Brazilian Port

16. Study and implementation of a connected digit recognition system using continuous HMMs / Estudo e implementação de um sistema de reconhecimento de digitos conectados usando HMMs continuos
Neste trabalho, Modelos Ocultos de Markov Contínuos (HMMC) baseados em palavras e independentes de locutor são incorporados a um sistema de reconhecimento de dígitos conectados baseado em HMMs discretos do Laboratório de Processamento Digital de Sinais de Multimídia em Tempo Real da Faculdade de Engenharia Elétrica da UNICAMP, visando aperfeiçoar a pl

17. Molecular cloning of a ligand for the EPH-related receptor protein-tyrosine kinase Htk.
Htk is a receptor protein-tyrosine kinase that is related to the EPH subfamily of tyrosine kinases. The receptor has a wide tissue distribution including expression in several myeloid hematopoietic cell lines. Using an Htk-Fc fusion protein, a protein ligand for this receptor was expression cloned from the murine kidney mesangial cell line SV40MES 13. The Ht

18. G1 cyclin degradation: the PEST motif of yeast Cln2 is necessary, but not sufficient, for rapid protein turnover.
The 545-residue Cln2 protein, like the other G1 cyclins of Saccharomyces cerevisiae, is a very unstable protein. This instability is thought to play a critical role in regulating cell cycle progression. The carboxyl-terminal domains of Cln2 and the other G1 cyclins contain sequences rich in Pro, Glu (and Asp), Ser, and Thr (so-called PEST motifs) that have b

19. Mitotic Degradation of Human Thymidine Kinase 1 Is Dependent on the Anaphase-Promoting Complex/Cyclosome-Cdh1-Mediated Pathway
The expression of human thymidine kinase 1 (hTK1) is highly dependent on the growth states and cell cycle stages in mammalian cells. The amount of hTK1 is significantly increased in the cells during progression to the S and M phases, and becomes barely detectable in the early G1 phase by a proteolytic control during mitotic exit. This tight regulation is imp

20. The effect of selected antioxidants on the kinetics of changes in the stability of an HTK solution: A technical note
The effect of selected antioxidants (vitamin C, cysteine, fumaric acid) on the stability of a 0.3-mM solution of HTK has been determined. The stability of the HTK solution was determined using the changes in histidine content at elevated temperatures. The rate of the amino acid decomposition in this solution was 42.3% lower than in a solution without an anti

21. Temporal regulation of cyclin A-p107 and p33cdk2 complexes binding to a human thymidine kinase promoter element important for G1-S phase transcriptional regulation.
The cyclins are an extensive family of proteins whose cell cycle-dependent synthesis is postulated to control multiple events during the cell cycle. The synthesis of A-type cyclins begins at the start of S phase. In mammalian cells, association with the cdc-type kinases suggests that cyclin A complexes are important for DNA replication and regulating other D

22. Carcinogens can induce homologous recombination between duplicated chromosomal sequences in mouse L cells.
The ability of a series of DNA-damaging agents to induce homologous intrachromosomal recombination between duplicated genes in the chromosome of mouse cells was investigated. The target cells were the thymidine kinase-deficient mouse L-cell strain 333M, which contains a single integrated copy of a plasmid with two herpes simplex virus thymidine kinase (Htk)

23. Immunoglobulin heavy chain switch region recombination within a retroviral vector in murine pre-B cells.
We have employed a retroviral vector, ZN(Smu/S gamma 2b)tk1, as a substrate for detecting the presence of immunoglobulin heavy chain constant region (CH) gene switch (S) recombination activity in murine pre-B cells. ZN(Smu/S gamma 2b)tk1 contains a neomycin (neo) resistance gene in addition to the herpes simplex virus thymidine kinase (Htk) gene which is pos

24. Effect of nucleotide excision repair in human cells on intrachromosomal homologous recombination induced by UV and 1-nitrosopyrene.
To study the role of nucleotide excision repair in the induction of intrachromosomal homologous recombination in mammalian cells, we introduced a plasmid containing a substrate for recombination into three human cell lines that differ in their repair capacity and compared the frequency of recombination induced by UV radiation and by 1-nitrosopyrene.
