The parameters of mixed speeches are estimated by searching in the neighbor area of given pitches to minimize the error between the original and the synthetic spectrums. The effectiveness of the proposed algorithm to separate close frequencies is demonstrated.展开更多

The probes under study have been excited with two types of sources: a laser diode (LD) and light-emitting diodes (LEDs) emitting in the UV and in the visible range. Total luminescence spectra were recorded by measuring the emission spectra in the range 350-720 nm at excitation wavelengths from 375 to 450 nm. The excitation-emission matrices have been obtained and two basic fluorescence regions in the visible have been outlined. On this basis the fluorescence spectra of the oils have been subdivided into three categories depending on the prevalence of the fluorescence maxima. The samples show differences in their fluorescence spectra. The latter fact shows that fluorescence spectroscopy can be used for the quick identification of edible oils. The fatty acid, the tocopherol, the beta-carotene and chlorophyll contents in the analyzed oils have been studied. It is shown that some of the types of oils differ significantly from each other by the first derivatives of their fluorescence spectra. There also exist color differences between the groups of vegetable oils under study.展开更多

Methods:Ninety-one eligible patients with Broca's aphasia after cerebral stroke were randomized into an observation group and a control group. Forty-six cases in the observation group were intervened by scalp acupuncture plus speech rehabilitation, while 45 cases in the control group were treated by speech rehabilitation alone. The aphasia battery of Chinese (ABC) and Boston diagnostic aphasia examination (BDAE) were adopted to evaluate the clinical efficacy. Results:After the treatment, the scores of oral expression, reading and writing and global score in the observation group were significantly higher than those in the control group (allP〈0.05). There was a significant difference in comparing the BDAE grading between the two groups after the treatment (P〈0.05). After intervention, the basically-recovered plus markedly-effective rate was 45.7% in the observation group versus 24.4% in the control group, and the between-group difference was statistically significant (P〈0.05). Conclusion:Scalp acupuncture plus speech rehabilitation is effective in treating Broca's aphasia after cerebral stroke, and worth promoting.展开更多
