Tone plays an important lexical role in spoken tonal languages like Mandarin Chinese. In this paper we propose a two-pass search strategy for improving tonal syllable recognition performance. In the first pass, instantaneous F0 information is employed along with corresponding cepstral information in a 2-stream HMM based decoding. The stream which(More)
BACKGROUND Propofol and sevoflurane are widely used in clinical anesthesia, and both have been reported to exert a protective effect in organ ischemia/reperfusion (IR). This study aims to investigate and compare the effects of propofol and sevoflurane on liver ischemia/reperfusion and the precise molecular mechanism. METHODS AND MATERIALS Rats were(More)
LSP has many advantages for speech representation, especially correlates well to spectrum formants as long as the LSP parameters are strictly ordered and bounded. This ordering property cannot be guaranteed during HMM-based speech synthesis when LSP is adopted as the spectrum feature, because diagonal covariance is utilized and correlation between LSP(More)
Tone plays an important role in recognizing spoken tonal languages like Chinese. However, the F0 contour discontinuity between voiced and unvoiced segments has traditionally been a bottleneck in modeling tone contour for automatic speech recognition and synthesis and various heuristic approaches were proposed to get around the problem. The Multi-Space(More)
Dopamine (DA), a neurotransmitter, was previously shown to have anti-inflammatory effects. However, its role in ventilator-induced lung injury (VILI) has not been explicitly demonstrated. This study aimed to investigate the therapeutic efficacy and molecular mechanisms of dopamine in VILI. Rats were treated with dopamine during mechanical ventilation.(More)
Cartographic drawing from manual work to computer-aided design has made a great achievement. We can interactively draw, edit, manipulate, render geographical map by means of computer drawing applications. These drawing functionalities, up to now, are mainly accomplished by Windows applications, not Web applications. With the developing of Rich Internet(More)
AIMS Ischemic heart disease is a leading cause of death and disability worldwide. Despite recent advances, there is no effective therapy for preventing myocardial ischemia-reperfusion (I/R) injury. In this study, we aimed to examine the therapeutic effect of scutellarin, a flavone isolated from the traditional Chinese medicine Scutellaria barbata and(More)
