This paper introduces the speech synthesis systems developed by USTC and iFlytek for Blizzard Challenge 2007. These two systems are both HMM-based ones and employ similar training algorithms, where contextual dependent HMMs for spectrum, F0 and duration are estimated according to the acoustic features and contextual information of training database.(More)
Dehydroepiandrosterone sulfate (DHEAS) is one of the most important neuroactive steroids. The present study examined the effect of DHEAS on spontaneous and evoked glutamate release in the pyramidal cells of layers V and VI of the rat prelimbic cortex by using whole-cell patch-clamp recordings in slices and further investigated its mechanism. The results(More)
Increasing evidence demonstrates that different opioids, while acting μ opioid receptors, can activate distinct downstream responses, a phenomenon termed functional selectivity or biased agonism. The present study designed experiments to test whether the μ receptor agonist morphine and D-Ala(2), N-Me-Phe(4), Gly(5)-ol-enkephalin (DAMGO) had a different(More)
Adrenomedullin (ADM) has the vasodilatory properties and involves in the pathogenesis of vascular calcification. ADM could be degraded into more than six fragments in the body, including ADM(27-52), and we suppose the degrading fragments from ADM do the same bioactivities as derived peptides from pro-adrenomedullin. The present study carries forward by(More)
In this paper, a corpus-based speech synthesis system KB2006 was developed using the speech database provided by Blizzard Challenge 2006. We proposed a novel unit selection method called multi-tier non-uniform unit selection in our corpus-base speech synthesis system. Non-uniform unit (NUU) in our system was defined as a unit sequences that contains one or(More)
A clonal selection based memetic algorithm is proposed for solving job shop scheduling problems in this paper. In the proposed algorithm, the clonal selection and the local search mechanism are designed to enhance exploration and exploitation. In the clonal selection mechanism, clonal selection, hypermutation and receptor edit theories are presented to(More)
The role of TiO 2 thin films deposited by atomic layer deposition on p-InP photocathodes used for solar hydrogen generation was examined. It was found that, in addition to its previously reported corrosion protection role, the large valence band offset between TiO 2 and InP creates an energy barrier for holes reaching the surface. Also, the conduction band(More)
Plasma-enhanced atomic layer deposition of cobalt oxide onto nanotextured p(+)n-Si devices enables efficient photoelectrochemical water oxidation and effective protection of Si from corrosion at high pH (pH 13.6). A photocurrent density of 17 mA/cm(2) at 1.23 V vs RHE, saturation current density of 30 mA/cm(2), and photovoltage greater than 600 mV were(More)
